Superyachts are notoriously dirty luxury toys, with a single billionaire’s boat emitting as much as 7,020 tons of CO2 per year. And while it’s unlikely uber-wealthy shoppers are going to forgo from their statement vessels anytime soon, at the very least there’s now a chance to make superyachts greener. That’s the idea behind the new Project 821, billed as the world’s first hydrogen fuel cell superyacht.

Announced over the weekend by Danish shipyard cooperative Feadship, Project 821 arrives following five years of design and construction. Measuring a massive 260-feet-long, the zero-diesel boat reportedly sails shorter distances than standard superyachts on the market, but still operates its hotel load and amenities using completely emissionless green hydrogen power.

Hydrogen cells generate power by turning extremely lightweight liquid hydrogen into electricity stored in lithium-ion batteries. But unlike fossil fuel engines’ noxious smoke and other pollutants, hydrogen cells only emit harmless water vapor. The technology remained cost-prohibitive and logistically challenging for years, but recent advancements have allowed designers to start integrating the green alternative into cars, planes, and boats.

There are still hurdles, however. Although lightweight, liquid hydrogen must be housed in massive, double-walled -423.4 degrees Fahrenheit cryogenic storage tanks within a dedicated section of the vessel. According to Feadship, liquid hydrogen requires 8-10 times more storage space for the same amount of energy created by diesel fuel. That—along with 16 fuel cells, a switchboard connection for the DC electrical grid, and water vapor emission vent stacks—necessitated adding an extra 13-feet to the vessel’s original specifications. But these size requirements ironically makes superyachts such as Project 821 arguably ideal for hydrogen fuel cell integration.

And it certainly sounds like Project 821 fulfills the “superyacht” prerequisites, with five decks above the waterline and two below it. The 14 balconies and seven fold-out platforms also house a pool, Jacuzzi, steam room, two bedrooms, two bathrooms, gym, pantry, fireplace-equipped offices, living room, library, and a full walkaround deck.

Such luxuries, however, will need to remain relatively close-to-harbor for the time being. Project 821 still isn’t capable of generating and storing enough power to embark on lengthy crossings, but it can handle an “entire week’s worth of silent operation at anchor or [briefly] navigating emission-free at 10 knots while leaving harbors or cruising in protected marine zones,” according to Feadship.

[Related: This liquid hydrogen-powered plane successfully completed its first test flights.]

“We have now shown that cryogenic storage of liquified hydrogen in the interior of a superyacht is a viable solution,” Feadship Director and Royal Van Lent Shipyard CEO Jan-Bart Verkuyl said in the recent announcement, adding that “additional fuel cell innovations… are on the near horizon.”

Of course, the greenest solution remains completely divesting from ostentatious, multimillion-dollar vanity flotillas before rising sea levels (and angry orcas) overwhelm even the wealthiest billionaires’ harbors. But it’s at least somewhat nice to see a new eco-friendly advancement on the market—even if it still looks like a Bond villain’s getaway vehicle.

Acura’s ZDX EV was developed jointly with GM. Kristin Shaw/PopSci

Acura’s new ZDX Type S is the most powerful SUV the brand has ever produced, generating nearly 500 horsepower and maxing out at 544 pound-feet of torque. In other words, it’s punchy in all the best ways. The automaker is quick to point out that ZDX has more torque than its hybrid NSX Type S supercar and more horsepower than other luxury EVs like the Mercedes-Benz EQE 500 and Audi’s SQ8 e-tron. And it’s all electric.

Like the Honda Prologue, the ZDX was built side-by-side with engineers from General Motors. Drawing power from a 102-kWh GM Ultium battery pack, Acura’s EV shares several components with Cadillac’s elegant Lyriq and Chevrolet’s Blazer EV. In fact, the exterior dimensions of the ZDX are the same as the Lyriq’s and the ZDX was designed at GM headquarters in Michigan.

The pairing of the American legacy automaker with a Japanese manufacturer is an unusual one. Does this partnership work for Acura? We drove the ZDX on a variety of roads in southern California to find out.

Two motors, big power boost

Somewhat ironically–and perhaps with a cheeky wink–the ZDX recycles the name of a previous gas-powered Acura model. With the zero-emissions movement ramping up in recent years, it made sense to revive the Z moniker.

Boasting an EPA-estimated 313-mile range with the single-motor, rear-wheel-drive setup, the ZDX can power up at a DC fast charging station and gain up to 81 miles of range in about 10 minutes. It takes a shade longer than 40 minutes to reach 80 percent, or 250 miles. Opting for the dual-motor, all-wheel drive version reduces the range slightly to 304 miles, and the top-performing Type S gets 278 miles before requiring a full charge.

Compared to some of its all-electric rivals from Kia, Hyundai, and Genesis, the ZDX takes significantly longer to charge, which may be a deterrent for those without charging stations at home. On the other hand, the Acura EV has more range and more power.

As a bonus, the ZDX is equipped with a high-end 18-speaker Bang & Olufsen audio setup, an Acura first. Danish company Bang & Olufsen makes sound systems for Lamborghini, Bentley, Audi, and others, so this new vehicle is in good company. In the EV theme, Eddie Grant’s “Electric Avenue” or Børns “Electric Love” are apt candidates for a ZDX soundtrack.  

Economies of scale through a GM partnership

As it’s so for the Prologue, GM provided the battery, frame, suspension, chassis, powertrain, and electrical architecture, while Acura built everything above the chassis. That doesn’t include some of the interior switchgear (knobs and buttons). 

As we noticed when we tested the Honda Prologue earlier this year, the drive mode button is located to the left of the steering wheel, making it difficult to locate and activate easily while driving. It’s worth finding, though, because it activates a useful 25 millimeter lift in snow mode or it hunkers down by 15 millimeters in sport mode for improved aerodynamics.    

The engineers chose to carry over GM’s one-pedal driving for both the Prologue and the ZDX as is without any alterations. 

“We didn’t change a thing,” ZDX Development Leader John Hwang told PopSci in February. “When we were benchmarking and setting targets, we liked how GM was executing this feature, so we said, ‘Don’t touch it. It’s not broken.’”

Hwang says the concept of the Prologue and ZDX are very different. Honda’s EV has a more mainstream feel and employs front-wheel drive or all-wheel drive, while the Acura has a much larger battery pack and the car is tuned for a more premium dynamic ride with rear-wheel drive or all-wheel drive.

What’s next?

Ultimately, Acura’s first EV appears to be a solid initial effort. That said, there’s room for the brand to dig deep into its own engineering expertise for its next EV without GM. We’d love to see Acura find a way to expand upon the genius of its hybrid NSX, which was powered by three electric motors working together with a 3.5-liter V6 engine.

However, Acura clearly stated several months ago that it was finished with hybrids. Instead, executives revealed a plan for a pilot production of solid-state batteries along with more research into hydrogen-powered vehicles. Hydrogen fuel cells are something that both Acura and GM are interested in pursuing, and while the automakers may have scrapped their plans for a smaller, more affordable EV collaboration, that doesn’t mean the partnership is completely kaput.

“The ZDX will have a complete lifecycle and there will be a refresh, so there is still a full team on the Honda/Acura side and a full team on the GM side,” Acura spokesman Jake Berg told PopSci. “This is definitely not the last time we’re collaborating with GM.”

The ZDX qualifies for the full federal $7,500 tax credit, putting the starting price at $57,500. It’s worth considering the extra $600 to get the ZDX in a luminous shade of Double Apex Blue Pearl, developed in-house by Acura’s color and materials team.

Say goodbye to dummy buttons and hello to the most standard power in the car's history.

The post The 2025 Toyota Camry is hybrid-only and it’s more powerful than ever appeared first on Popular Science.

Toyota upgraded the suspension and tuning for a better ride. Camry

Toyota’s trusty Camry sedan has been around for more than two decades. Once a compact, boxy car, the Camry has become a predictable mainstay in America, a beloved four-door fit for everything from transporting clients to hauling families all over town. The humble Camry isn’t ready to lie down and play dead any time soon, either. In fact, it has a few new tricks up its… exhaust pipe, if you will.

Now sold exclusively as a hybrid for its ninth generation, the 2025 Camry is equipped with a steady 2.5-liter, 4-cylinder engine. Paired with a permanent magnet synchronous motor for a combined 225 horsepower with front-wheel drive and 232 horsepower with on-demand all-wheel drive, this Camry starts off with the most standard power in its history. 

This isn’t Toyota’s first time selling the Camry as a hybrid, but this is the first time that it’s on the market without a non-hybrid option. In a world that seems to have gone gaga for EVs, this hybrid can achieve up to 51 miles per gallon, which is a respectfully efficient option. All starting at $28,400, which is more than $400 less than the outgoing Camry Hybrid base model.

Retuned suspension 

The Camry has been a best-selling car in the U.S. for many years already, so updating it for 2025 required some finesse. Toyota engineers thirsted for ride improvements but they didn’t want to alienate its current fan base, says chief engineer for the Camry Mark DeJongh.

“We weren’t hearing anything negative about the current Camry, but it was our passion to make it better,” explains DeJongh. “We wanted to push the handling a little more because I knew we could, but without affecting ride comfort.” 

Toyota once again opted for a MacPherson strut up front, which uses a coil spring wrapped around a tubular shock absorber. The strut tower is mounted to the frame, which provides an upper anchor point, negating the need for an upper control arm; that’s important because there’s not as much room as there is in the back half of the car due to the placement of the engine.

In the rear, the Camry is equipped with a multi-link suspension that allows for a lively ride while keeping the car steady. This suspension unit controls the front-to-back and side-to-side movements of the car, providing the sedan with a compliant ride that doesn’t veer into sterile territory. The entire suspension system got a makeover for 2025 with precise tuning by the engineering team.  

“The shocks and springs are what primarily allows the tires and wheels to move up and down to keep you comfortable on the road,” DeJongh says. “We tuned the spring rate, and then we tuned the absorber [shocks] for damping force.” 

Set a little lower and wider in the rear than in the previous generation, the 2025 Camry’s multi-link suspension includes a longer arm that allows for better dynamics, DeJongh explains. As a result, the car will feel natural and predictable. 

“The car should be doing what you want and expect it to,” he says. “It’s a Camry. You don’t want to be surprised.”

This Camry also includes a new electrical platform. Between that and software development, DeJongh estimates that about half of the engineering team’s time was spent on the software and electrical platform versus the mechanical elements. 

“Software in the future is going to completely take over,” he predicts.

Brakes and buttons

Toyota Vehicle Marketing and Communications Senior Analyst Chad Deschenes adds that one unsung enhancement to the 2025 Camry is the interior button layout. For many vehicles sold in the U.S. the interior integrates a button template that may leave “dummy plug buttons” where a feature might be included in a higher trim. For instance, if a customer chooses a base model there might be a blank space where an upgrade might feature a heated seat button. 

“The interior team spent a lot of time making sure that customers don’t have dummy buttons,” Deschenes says. “Your friends and family won’t ever see a dead button.”

When he was first assigned to the new Camry, DeJongh says, he knew the team could improve the steering response, wind noise, noise and vibration, and ride comfort. And he’s especially proud of the work they’ve done on the brakes and the steering. 

“Honestly, I think the brakes are one of the things we have done; you don’t even feel the regeneration,” he says. “In past hybrid generations, you could sometimes feel when the regen kicked in when braking. With this model, we have completely eliminated that.”

One of the improvements to the braking setup is a new booster system with an extra pump and software tuning. The brake booster plays a critical role in amplifying the force applied to the brake pedal by your foot. Toyota’s parts department explains that this system works by utilizing hydraulic pressure, stored in the accumulator, to assist the brake system when the pedal is engaged.

DeJongh says during development, he was eager to test the wind noise improvements and wanted to drive it. The first time he got behind the wheel, the team wasn’t finished tuning the suspension or the engine, but he could feel the difference, he says. And he expects it to continue getting better. 

“I’ve told the engineers that it’s better than it should be. It’s beyond where I thought we could take it,” he says.

Tire toxicity faces fresh scrutiny after salmon die-offs https://www.popsci.com/environment/tire-toxicity/ Sun, 28 Apr 2024 16:00:00 +0000 https://www.popsci.com/?p=612316

This article was originally published on KFF Health News.

For decades, concerns about automobile pollution have focused on what comes out of the tailpipe. Now, researchers and regulators say, we need to pay more attention to toxic emissions from tires as vehicles roll down the road.

At the top of the list of worries is a chemical called 6PPD, which is added to rubber tires to help them last longer. When tires wear on pavement, 6PPD is released. It reacts with ozone to become a different chemical, 6PPD-q, which can be extremely toxic—so much so that it has been linked to repeated fish kills in Washington state.

The trouble with tires doesn’t stop there. Tires are made primarily of natural rubber and synthetic rubber, but they contain hundreds of other ingredients, often including steel and heavy metals such as copper, lead, cadmium, and zinc.

As car tires wear, the rubber disappears in particles, both bits that can be seen with the naked eye and microparticles. Testing by a British company, Emissions Analytics, found that a car’s tires emit 1 trillion ultrafine particles per kilometer driven—from 5 to 9 pounds of rubber per internal combustion car per year.

And what’s in those particles is a mystery, because tire ingredients are proprietary.

“You’ve got a chemical cocktail in these tires that no one really understands and is kept highly confidential by the tire manufacturers,” said Nick Molden, CEO of Emissions Analytics. “We struggle to think of another consumer product that is so prevalent in the world and used by virtually everyone, where there is so little known of what is in them.”

Regulators have only begun to address the toxic tire problem, though there has been some action on 6PPD.

The chemical was identified by a team of researchers, led by scientists at Washington State University and the University of Washington, who were trying to determine why coho salmon returning to Seattle-area creeks to spawn were dying in large numbers.

Working for the Washington Stormwater Center, the scientists tested some 2,000 substances to determine which one was causing the die-offs, and in 2020 they announced they’d found the culprit: 6PPD.

The Yurok Tribe in Northern California, along with two other West Coast Native American tribes, have petitioned the Environmental Protection Agency to prohibit the chemical. The EPA said it is considering new rules governing the chemical. “We could not sit idle while 6PPD kills the fish that sustain us,” said Joseph L. James, chairman of the Yurok Tribe, in a statement. “This lethal toxin has no place in any salmon-bearing watershed.”

California has begun taking steps to regulate the chemical, last year classifying tires containing it as a “priority product,” which requires manufacturers to search for and test substitutes.

“6PPD plays a crucial role in the safety of tires on California’s roads and, currently, there are no widely available safer alternatives,” said Karl Palmer, a deputy director at the state’s Department of Toxic Substances Control. “For this reason, our framework is ideally suited for identifying alternatives to 6PPD that ensure the continued safety of tires on California’s roads while protecting California’s fish populations and the communities that rely on them.”

The U.S. Tire Manufacturers Association says it has mobilized a consortium of 16 tire manufacturers to carry out an analysis of alternatives. Anne Forristall Luke, USTMA president and CEO, said it “will yield the most effective and exhaustive review possible of whether a safer alternative to 6PPD in tires currently exists.”

Molden, however, said there is a catch. “If they don’t investigate, they aren’t allowed to sell in the state of California,” he said. “If they investigate and don’t find an alternative, they can go on selling. They don’t have to find a substitute. And today there is no alternative to 6PPD.”

California is also studying a request by the California Stormwater Quality Association to classify tires containing zinc, a heavy metal, as a priority product, requiring manufacturers to search for an alternative. Zinc is used in the vulcanization process to increase the strength of the rubber.

When it comes to tire particles, though, there hasn’t been any action, even as the problem worsens with the proliferation of electric cars. Because of their quicker acceleration and greater torque, electric vehicles wear out tires faster and emit an estimated 20% more tire particles than the average gas-powered car.

recent study in Southern California found tire and brake emissions in Anaheim accounted for 30% of PM2.5, a small-particulate air pollutant, while exhaust emissions accounted for 19%. Tests by Emissions Analytics have found that tires produce up to 2,000 times as much particle pollution by mass as tailpipes.

These particles end up in water and air and are often ingested. Ultrafine particles, even smaller than PM2.5, are also emitted by tires and can be inhaled and travel directly to the brain. New research suggests tire microparticles should be classified as a pollutant of “high concern.”

In a report issued last year, researchers at Imperial College London said the particles could affect the heart, lungs, and reproductive organs and cause cancer.

People who live or work along roadways, often low-income, are exposed to more of the toxic substances.

Tires are also a major source of microplastics. More than three-quarters of microplastics entering the ocean come from the synthetic rubber in tires, according to a report from the Pew Charitable Trusts and the British company Systemiq.

And there are still a great many unknowns in tire emissions, which can be especially complex to analyze because heat and pressure can transform tire ingredients into other compounds.

One outstanding research question is whether 6PPD-q affects people, and what health problems, if any, it could cause. A recent study published in Environmental Science & Technology Letters found high levels of the chemical in urine samples from a region of South China, with levels highest in pregnant women.

The discovery of 6PPD-q, Molden said, has sparked fresh interest in the health and environmental impacts of tires, and he expects an abundance of new research in the coming years. “The jigsaw pieces are coming together,” he said. “But it’s a thousand-piece jigsaw, not a 200-piece jigsaw.”

Can the Technology and Design Center help make the century-old company cool again?

The post Inside the new $2 billion campus that GM hopes will launch it into the future appeared first on Popular Science.

GM Technical Center and Design Center in Michigan. GM

On the floor of General Motors’ new Design West building, various concepts and work-in-progress next-generation vehicles dot the vast, open space. From a level above and behind glass, all is quiet. Everyone appears to be wearing soft-soled, comfortable shoes, as the place is huge and walking is required. It’s not until you step onto the cement floor that you hear a confluence of murmurs and sounds from hundreds of people all working toward the same goal: to propel the legacy automaker forward as quickly and efficiently as possible. 

How do car designers peer eight to 10 years into the future to create vehicles that not only look good but will sell? In this building, GM creatives have moved into a new house, and the ideas are flowing. Here at the intersection of art, design, engineering, and technology, GM is flexing the vehicles the public already knows are coming, plus many more that very few people have seen. Except for those working in this building, of course. 

It’s all part of a $2 billion upgrade to the Technical Center campus, a significant investment for this century-old automaking conglomerate. Already, the 2025 Buick Enclave three-row SUV was uncovered recently with a clear nod to the Buick Wildcat EV concept unveiled in 2022. Sleek and angular with aerodynamic lines that suggest speed, the Wildcat seems to be the audacious kind of model inspiring future ideas and encouraging a second look at what may have been a lackluster brand in the recent past.

Using every resource available

When the GM campus was first built in the Detroit area in 1956, arriving on site was like “driving into the future,” says a GM spokesperson during my recent tour. Today’s updates leap forward another generation while keeping tokens from the past. For example, in the new conference room that hangs over the portico, a Cadillac goddess sculpture sits on a piece of elm from a tree that had been cut to make way for this building. Sculpted wood wraps around the wall near the lobby, finely crafted by three generations of woodworkers employed by GM.

In the Design West facility, collaboration is easier than it was before, as design teams have better access to varied physical scenarios for quicker and more impactful design reviews, a GM spokesperson told me. The floor-to-ceiling windows enable more natural light, and vehicles can be more easily moved on to the courtyard for viewing outdoors.

The new Digital Design Visualization Center includes a full audio setup with capacity up to 120 decibels–basically, the noise level of a jet plane–and a nearly 56-foot-wide screen with more than 76 million pixels. Virtual tools are incorporated into each studio area to enable real-time, on-demand global design collaboration, and it seems the line between where the computers start and people stop (and vice versa) is fluid.

3D modeling still reigns

Forty-four high-tech mill sites dot the surface, standing ready to carve giant blocks of clay into the desired shapes before sculptors take over with specialized tools. These are five-axis mills, capable of cutting across three distinct linear axes. At the same time, it rotates on two vertical axes to process five sides in total. Sculptors learn the software to program the mills so the process is hand in glove.

GM hasn’t completely eschewed analog techniques for vehicle creation, however. Supremely talented artisans sculpt details into clay models after the mills have completed their part of the job.

“We’ve been predicting coming off clay models for a long time,” says GM Senior Vice President of Global Design Michael Simcoe. “But this is an art form. By using a physical model, you have a unique reaction in three dimensions; judging proportions and scale is difficult, virtually.”

Side by side with the all-clay models are those that are partly cloaked in Di-Noc, a stretchy film used for decades in the automotive industry for wraps and color representation. Massive company 3M acquired Di-Noc in the 1960s and still uses the name. Today, GM staff in the Design West building apply it to clay models to help designers see the reflection of light on the surface as it plays on the body of the car.

Tearing down the walls

There’s more space in the new building for show and tell, and you can bet each of the automakers–Cadillac, Chevrolet, Buick, and GM–are checking each other out. There’s a sense of peripheral inspiration over one-upmanship. Even those on the virtual modeling side are nearby under an overhang to manage the influx of light on their computer screens. If the old buildings were siloed and compartmentalized, this is the exact opposite. GM’s world is topsy turvy in the most logical, ambitious ways.

On top of the new building, refreshed technology, and updated machinery, there are about 40 art installations throughout Design West, all created by current and past GM designers, creatives, sculptors, and fabrication shop employees. There is a large collage stretching four yards or more made from fabric swatches of all colors from past and current models. A massive, heavy aluminum piece of wall art was painted with various finishes. Employees host art shows on a regular basis to showcase what the designers can do beyond industrial sketches.

I can’t tell you about everything I saw on that design floor. There’s quite a bit of which I’m sworn to secrecy; at least for now. But if Buick’s Wildcat EV concept is any indication of the daring direction GM is taking into the next decade, it looks like that billion-dollar investment will pay off in spades.

Update: The original version of this story stated GM spent $1 billion on the new facility, but a GM representative has said the investment is now $2 billion. The headline and story have been updated to reflect the correct number.

Cybertruck recalled
Cybertruck owners claim an issue with their accelerator pad pedal caused the vehicle is unintentionally keep speeding up. Tesla

Tesla is recalling nearly every one of its Cybertrucks due to a faulty accelerator pedal that could get stuck in place when pressed down. The mass recall, which will require a physical maintenance fix, comes less than five months after the company began shipping the vehicle.

In its recall notice issued this week, the National Highway Traffic Safety Administration (NHTSA) said the pad on the truck’s accelerator could become “dislodged” if enough force was applied to it. Once the pad was dislodged, the pedal could become “trapped in the interior rim above the pedal.” If that were to happen, the NHTSA notes, the truck could continue accelerating even if the driver were to apply the brakes which could ultimately increase the risk of a crash or collision. The recall blames the malfunction on an unapproved introduction of lubricant to the pad during the manufacturing process. That lubricant, the recall notes, was soap. 

“If the condition [faulty accelerator pad] is present and the driver attempts to apply the accelerator pedal, the driver will detect the condition through immediate compromised performance and operation of the pedal,” the NHTSA wrote. “In addition, if the condition is present when the driver applies the brake pedal, the driver will receive an audible and visual alert that both brake and accelerator pedals are being pressed.” 

Tesla voluntarily agreed to recall the trucks and says it will “replace or rework” the accelerator pedal free of charge. The recall affects 3,878 Cyber Trucks manufactured between November 13, 2023, to April 4, 2024, which likely accounts for nearly all of trucks shipped to customers to date. When reached for comment, the NHTSA pointed PopSci to its recall notice. Tesla did not immediately respond to PopSci’s request for comment. Elon Musk, who has previously boasted about the vehicle’s “bulletproof” durability, acknowledged the recall on X, formerly known as Twitter. 

“There were no injuries or accidents because of this,” Musk wrote. “We are just being very cautious.”

Some Cybertruck owners began sharing their experiences of the accelerator getting stuck on social media last week. One Californian Cybertuck owner named Jose Martinez posted a video on TikTok explaining how the pad on his accelerator dislodged and got stuck on the driver-side carpet. Another Cybertruck owner who claims they experienced the issue says his truck continued accelerating even when he pressed on the brake pedal. Eventually, the driver alleged, he hit a light pole. 

Unlike other Tesla recalls 

Tesla owners over the years have come to expect recall notices with relative frequency. In just three years between 2020 and 2023, Tesla had 24 recalls of this Model Y SUV. In the past, Tesla has recalled vehicles for brake safety concerns, issues with its assisted driving software, and illegible warning lights. The sheer volume of the recalls sets the company apart. A 2022 analysis conducted by the price tracking firm iSeeCars.com found Tesla experienced the most recalls of any car brand that year, and by a wide margin. Tesla is somewhat unique though since the vast majority of those recalls are addressable via internet enabled, over-the-air updates. The Cybertruck recall is a notable outlier. Customers will actually have to physically have the truck serviced to address the accelerator issue. 

This isn’t the first issue Cybertruck owners have experienced in the vehicle’s brief life-span. Earlier this year, multiple owners said they saw small orange dots appear on the surface of their vehicles which resembled rust. One owner claims the discoloration occurs almost immediately after driving through a rain just one day after purchasing the car. A Tesla repair technician allegedly told one of the affected drivers they had a “procedure” for dealing with the splotchy red specks. 

[ Related: Owners worry Cybertruck of the future rusts after rain ]

Both the rust like spots and the apparent soap-induced accelerator pad issue appear to contradict Tesla’s branding of the Cybertruck as rugged, durable, off-road behemoth. Musk has previously referred to the vehicle as “badass” and possibly “the best product ever.”

Now with a 149-mile range, the tiny car is ready for urban driving, if America will have it.

In 2013, Italian automaker Fiat launched its first EV, the 500e. The car was sold only in California and Oregon and discontinued in 2019. Going back to the drawing board for a European-spec 2000 model, Fiat built a new EV-only platform for its next generation. The small EV has reached American shores once again with a renewed commitment and a slightly larger package; the 2024 Fiat 500e is 2.2 inches wider and 2.4 inches longer than its predecessor.

While the 2024 model is bigger, Fiat managed to trim 50 pounds from the overall weight for a total of 2,952 pounds. EVs tend to be heavier, like the 4,861-pound Hyundai Ioniq 5 or 4,000-pound Volvo EX30, so the 500e is noticeably light on its feet. Maxing out at 149 miles of range, Fiat’s new EV is made for city driving, and it’s right at home in Europe. But can it fit into the American lifestyle? We drove it on the city streets of Miami’s Wynwood art district to find out.

Small package, big hopes

In 1957, American cars were getting bigger and bigger. Creased metal adorned the back end of sedans like the Chevrolet Bel Air in the form of stylish fins, and trunks were massive. That wasn’t the case in Italy, where Fiat launched its 500–a tiny, rounded car that seemed to barely encase its occupants.

When the first 500e launched in 2013, EVs weren’t on the fast track they are today. The experiment was carefully controlled, and retracted before the pandemic turned the world upside-down in 2020. When it launched in 2013, the range was considered good; not so much anymore. 

“The 500e boasts an EPA-estimated range of 87 miles, an above-average number for an EV,” Edmunds reported in 2013. “Further, Fiat says its EV hatchback can fully charge in less than four hours from a 240-volt outlet, also a good figure for this class.” 

Things have changed a lot in 10 years, and 87 miles is no longer impressive. Fiat relaunched its 500e in 2020 in Europe with a new platform and more than doubled its range to 199 miles on the European testing cycle. Seeing the diminutive 500e’s success across the pond, Fiat’s hopes were high for the car’s American rebirth.

“We realized we had magic in a very small package,” Fiat North America Aamir Ahmed says. “When we’re talking electrification, many [cars] lose their character. And now we take an electric battery and power this car that’s filled with charisma.”

This is a very different message than the one offered by Fiat maestro and chief executive Sergio Macchione a decade ago. Frustrated by federal and state mandates that encourage automakers to build EVs, Marchionne rebelled against the status quo.

“I hope you don’t buy it because every time I sell one it costs me $14,000,” he told the audience at the Brookings Institution in 2014. “I’m honest enough to tell you that.”

Today’s 500e is primed for the current EV appetites, and it’s designed to be a city car for those who drive the average (according to AAA) 30 miles a day. At that rate, one could go nearly a week between charges, and as charging infrastructure ramps up, it could be as easy as charging up at the coffee shop. With 85 kW of DC fast charging capability, the 500e can go from 10 percent to 80 percent in 35 minutes, Fiat says.

Fresh engineering and Andrea Bocelli-influenced acoustics

Chief engineer Paolo Gribaldi has been working on the 500e for the last two years, and he says the time frame was the most challenging piece of this project; it had to be finished in 22 months. The 500e (cinquecento, in Italian) was designed on a purpose-built platform, the first created for EVs. It’s fitted with the same power source as its older cousin in Europe, a 42 kilowatt-hour nickel manganese cobalt battery. 

Sporting 17-inch wheels and lower-profile tires, the previous model’s 15-inch wheels look way too small when compared side by side. Slide behind the wheel, and there is no need for a “start” button. It starts up when it detects the key fob, much like Volkswagen’s ID.4. The flush door handles are lifted from its sibling company Maserati, also owned by Stellantis, which helps with both aerodynamics and economies of scale. Other enhancements are under the surface.

“The suspension uses a wider track than the previous generation to fit the larger battery,” Garibaldi explains. “Then there were improvements to the brake system.” 

Also cribbed from the European version is the set of drive modes, which Fiat calls Normal, Range, and Sherpa. Normal mode offers low regenerative braking and a driving experience that feels “normal” to those used to combustion-engine vehicles. Range mode tweaks the regen for typical-EV one-pedal driving, slowing the car to a stop when lifting your foot from the accelerator. Lastly, Sherpa mode optimizes range by reducing power from 117 horsepower to 90 horsepower and turning off the heating and cooling system. Equivalent to what others call “Eco” mode, the maximum speed is set to about 50 miles per hour, which is fine for urban driving. 

I tried it in each mode, and I can say that driving in Miami (or anywhere it’s warm, really) in Sherpa mode is not pleasant with the air conditioning off. Opening the windows is an option, but then you’re altering the aerodynamics and thus, range. I can see how it could be helpful if you’re limping home or into a charging station and need to stretch the miles as far as possible. Most gas-powered car fans will appreciate the seamless transition to EV in Normal range, which feels familiar, and Range mode is handy in stop-and-go traffic. 

Fiat isn’t above having a little fun with its new EV, and it tapped one of the most famous Italian musicians–tenor Andrea Bocelli–to create concert hall-level sound inside its “Inspired by Music” limited edition model. Once the car reaches 20 miles per hour for the first time after starting up, the 500e’s pedestrian alert “sings” a tune called “The Sound of 500” composed by Flavio Ibba and Marco Gualdi. It’s just another way to communicate its unmistakable Italianness to passersby. 

This car is iconic and fun to drive, and it fits perfectly into a city environment. It’s not perfect, nor is any car, but it’s worth a look for those seeking a compact, adorable EV with the ability to park just about anywhere. And it doesn’t hurt that it includes Maserati parts, either: a city car with big aspirations.

NASA’s Science Mission Directorate Heliophysics Division studies the nature of the sun and everything it touches. That includes the Earth, the atmosphere, and the magnetosphere, which is basically the planet’s force field against solar wind and radiation. As the United States amps up to a fever pitch due to today’s total solar eclipse, NASA is ground zero for the most interesting studies and history about this natural phenomenon.

Today the sun is more of a rock star than usual, with “eclipse parties” in full swing, and roadside stands selling commemorative t-shirts and cardboard viewing glasses are popping up all along the path of totality. Dr. Kelly Korreck, a heliophysicist and NASA’s eclipse lead, gave us the background on this captivating astro-event and offered tips on the best viewing areas.

We asked Dr. Korreck if watching the eclipse from a convertible (specifically, a tech-focused Audi S5 Cabriolet) would be a good idea, and she said it would be very appropriate. After all, besides safety glasses and a clear view of the sky, the only other thing you need is a great place to sit and lean your head back. 

As we waited for the clouds to clear from the sky, our photography team was a bit nervous. We got glimpses of the eclipse as the moon cast its great shadow, but would it clear? We’d soon find out.

Spoiler: It was amazing. Video: Audi

An eclipse ushers in boatloads of scientific data points

If the moon’s shadow doesn’t excite you, consider this: Albert Einstein published his theory of general relativity in 1915, but it wasn’t proven until the total solar eclipse of 1919 when Sir Arthur Eddington and his team measured the influence of the sun’s gravity on starlight.

Dr. Korreck has been fascinated by the biggest star in our universe–the sun, of course–since long before she earned her doctorate on the subject. Scientists have long used solar eclipses to make scientific discoveries, she says. Eclipses led us to the first detection of helium, for instance, and this one will continue to give scientists the opportunity to study the sun’s effect on the ionosphere. Disturbances in the ionospheric layer can cause blips in our GPS navigation systems and communications, especially radio waves.  

To that end, we tested the Audi S5’s unique Bluetooth-connected seatbelt microphones, which enable clear conversations even with the top down. Three thumbtack-sized microphones are built into the outward-facing side of the seatbelt, which makes talking to someone like a brilliant NASA heliophysicist even more interesting. We also kept an eye on the S5’s GPS system, which didn’t flinch.

Eclipses happen about every 18 months somewhere in the world, but only in the same place every 400 to 1000 years, Dr. Korreck told us. In fact, the last total solar eclipse in Austin, Texas was more than 600 years ago, in 1397. Austin didn’t even exist back then. And the next one won’t be until 2343, long after we’re all gone. 

“Any specific town or city normally only gets an eclipse between every 400 and 1,000 years,” Dr. Korreck says. “So it’s very rare to [see one] in a specific location, but somewhere on Earth is getting this special dance, this special alignment of the planets.” 

The reason this particular total eclipse is so unusual is because it’s occurring during the period of “solar maximum,” when the sun is most active. There’s even a chance to see “streamers,” which NASA says will look like bright, pink curls or loops emanating from the sun. Heliophysicists (and the entire scientific community) are excited about this eclipse, because of the length and the intensity of the sun’s magnetic field in this period of time. 

“We’re at four and a half minutes for this eclipse,” Dr. Korreck says. “It was only two and a half minutes maximum in 2017, but it’ll be six-ish minutes in 2045. So we have more to look forward to in 20 years.” 

It’s more than just a visual event

When the moon stands between the sun and the Earth, the temperature outside can drop quickly – up to 10 degrees. I turned on the heated headrest, which blows warm air onto my neck; a welcome feature when you’re chilly. In Texas, it’s hot more often than it’s cold, so typically I’d use the cool setting to whisper cooling air instead. During an eclipse, the shroud of shadow blocking the sun erases heat quickly. So the sky goes dark, the temperature falls, and there’s even a measurable sound component.

“We mapped the bright light of the sun to a flute sound,” Harvard astronomer Allyson Bieryla told CNN on Friday. “Then it goes to a midrange, which is a clarinet, and then during totality, it kind of goes down to a low clicking sound, and that clicking even slows down during totality.”

That doesn’t even count the chirps, croaks, whines, and other sounds of the animal and insect kingdom as they process the odd turn of light during the event

“I think in general, an eclipse is such a full body experience,” Dr. Korreck says. “It gets colder, the light changes, the shadow gets a bit sharper. It’s a way to really experience a celestial event more than just a visual. Take some time to really enjoy it and take advantage of the special alignment that we have.” 

As the moment of totality approached, nearby horses brayed and dogs barked, as if it were truly twilight. And then it happened: The clouds parted and the sky grew dark, the animals quieted, and a stillness blanketed the landscape. We could see solar flares peeking from behind the corona, and Venus appeared below the sun. Outside of the S5 Cabriolet, the car’s headlights and taillights cast a signature pattern. For a couple of minutes, time stood still, and then daylight crept in again. It’s something I’ll never forget.

Even hands-free, phones and their apps cause dangerously distracted driving https://www.popsci.com/technology/hands-free-distracted-driving/ Sat, 06 Apr 2024 13:00:00 +0000 https://www.popsci.com/?p=609255

This article was originally featured on The Conversation.

Do you ever use your cellphone while driving? Don’t feel too guilty about saying yes–nearly 60% of drivers admit to using their phone in hands-free mode while driving.

But don’t become complacent either. Using your cellphone in hands-free mode while driving is not a perfectly safe activity, despite the impression you might be getting from laws, marketing messages and the behavior of people around you.

Fatal crashes caused by driver distraction have not gone down significantly over time: Distraction caused 14% of fatal crashes in 2017 and 13% of fatal crashes in 2021. Given that these numbers are calculated based on police-reported crashes, many experts believe the actual number of crashes caused by driver distraction is much higher. For example, real-world crash data from teens indicates that 58% of their crashes are due to driver distraction.

I am a human factors engineer who studies how drivers interact with technology. I see a gap between what people are told and what people should do when it comes to using your cellphone behind the wheel.

Hands-free calling

Most U.S. states ban hand-held cellphone use while driving but allow hands-free devices. However, hands-free devices are still distracting. Talking on a hands-free phone and driving is multitasking, and humans are not good at doing two cognitively demanding tasks at the same time.

For example, having a phone conversation in hands-free mode while driving causes you to stop looking out for hazards on the road and gets you into more close calls where you slam on the brakes than if you were not on the phone.

[ Related: Too many screens? Why car safety experts want to bring back buttons ]

These detrimental effects last even after you end your call. There is a hangover effect: You can remain mentally distracted nearly 27 seconds after you finish using your cellphone. At 65 miles per hour, you’ve traveled nearly half a mile in 27 seconds.

Third-party apps

Third-party apps that connect your smartphone to your car’s interface, such ass Apple CarPlay and Android Auto, encourage you to use your phone in hands-free mode while driving. You can control things like music, navigation, text messaging and phone calls using voice commands and the car’s interface. IPhone users can connect their phones to more than 800 car models and Android phone users more than 500 models.

But is using these third-party apps while driving safe? Fifty-three percent of people say that if carmakers put the technology in vehicles, they must be safe. Though these third-party apps make cellphone use hands-free, they unintentionally cause you to look away from the road for dangerous amounts of time and they slow your reaction time.

Law-enforcement officers would like to remind you that distracted driving is a threat to the people around you, not just yourself.

Driving automation and distraction

Recent advances in technology have made driving a safer activity. Systems such as Cadillac Super Cruise and Tesla Autopilot control your steering and acceleration in limited situations, but they don’t mean you can text at will. Though it’s often lost in the marketing and enthusiasm for the systems, you are still required to pay attention to the road when you’re using them.

Research has shown that drivers using Level 2 automation, which combines adaptive cruise control with lane centering, are more likely to take their eyes off the road. Research also shows that watching a video or doing anything distracting while using these systems is unsafe–you stop looking at the road, and when you need to respond, it takes more time.

Some systems work to keep you focused on driving by monitoring your eye or head position to make sure you’re looking straight ahead. If your eyes are off the road for more than a few seconds, the systems alert you to bring your attention back to driving. This makes it difficult to get distracted by your phone.

Distracted driving awareness

April is Distracted Driving Awareness Month. Distracted driving–in hands-free mode, using a third-party app or when using driving automation–still claims thousands of lives each year in the U.S. Despite continual advances in vehicle technology, cellphone use while driving is likely to remain a challenging problem for the foreseeable future.

To discourage distracted driving, it’s important to look back to see what’s worked in the past to keep roads safe. Modifying the culture around distracted driving as well as comprehensive education, training and media campaigns, similar to “Click It or Ticket” to encourage seat belt use, are good examples of what works. To that end, on April 1, 2024, the National Highway Traffic Safety Administration launched the “Put the Phone Away or Pay” campaign to discourage distracted driving.

And for all of those who drive with children in the car, be sure to model safe behavior–they are watching and learning from you.

NASA has announced three finalists to pitch them their best moon car ideas by this time next year to use on upcoming Artemis lunar missions. During a press conference yesterday afternoon, the agency confirmed Intuitive Machines, Lunar Outpost, and Venturi Astrolab will all spend the next 12 months developing their Lunar Terrain Vehicle (LTV) concepts as part of the “feasibility task order.”

According to Vanessa Wyche, director of NASA’s Johnson Space Center in Houston, the final LTV will “greatly increase our astronauts’ ability to explore and conduct science on the lunar surface while also serving as a science platform between crewed missions.”

While neither Lunar Outpost nor Venturi Astrolab have been on the moon yet, they are planning uncrewed rover missions within the next couple years. In February, Intuitive Machines became the first privately funded company to successfully land on the lunar surface with its NASA-backed Odysseus spacecraft. Although “Odie” officially returned the US to the moon after an over-50 year hiatus, touchdown complications resulted in the craft landing on its side, severely limiting the extent of its mission.

[Related: NASA’s quirky new lunar rover will be the first to cruise the moon’s south pole.]

The last time astronauts zipped around on a moon buggy was back in 1971 during NASA’s Apollo 15 mission. The new LTV, like its Apollo predecessor, will only accommodate two people in an unpressurized cockpit—i.e. exposed to the harsh moon environment.

Once deployed, however, the LTV will differ from the Lunar Roving Vehicle in a few key aspects—most notably, it won’t always need someone at the steering wheel. While astronauts will pilot the LTV during their expeditions, the vehicle will be specifically designed for remote control once the Artemis crew is back home on Earth. In its initial May 2023 proposal call, the agency explained its LRV capabilities will be “similar to NASA’s Curiosity and Perseverance Mars rovers.” When NASA isn’t renting the LTV, the winning company will also be free to contract it out to private ventures in the meantime.

But while a promising lunar rover design is great to see on paper, companies will need to demonstrate their vehicle’s capabilities before NASA makes its final selection—and not just on some desert driving course here on Earth.

After reviewing the three proposals, NASA will issue a second task order to at least one of the finalists, requesting to see their prototype in action on the moon. That means the company (or companies) will need to plan and execute an independent lunar mission, deliver a working vehicle to the moon, and “validate its performance and safety.” Only once that little hurdle is cleared does NASA plan to greenlight one of the company’s rovers.

If everything goes smoothly, NASA’s Artemis V astronauts will use the winning LTV when they arrive near the moon’s south pole in 2030.

The science of supercharged engines and their distinct whine https://www.popsci.com/technology/science-of-superchargers-engine/ Wed, 03 Apr 2024 14:04:00 +0000 https://www.popsci.com/?p=609261

Inside a supercharger is the only place where whining is a good thing.

Superchargers add power to gas-powered engines. Dodge

Cars, especially fast cars, represent an experience that touches all the senses except taste (because biting down on metal is ill-advised). Every vehicle has a sound–even EVs–that identifies the type of powertrain propelling it. Once you’ve heard a Toyota hybrid system, it’s hard to mistake that sonorous tone for anything else. Honda hybrids have a similar sound but with their own inflection, like a Georgia native’s accent versus someone else’s twang in Texas.   

A supercharger has its own specific whine, especially inside muscle cars like a Dodge Challenger Hellcat. Hearing a Hellcat go by may send chills up your spine (as it does mine) as your brain recognizes the 717 to 800-plus horsepower at the ready. The noise itself isn’t the main attraction, though. Power is the big reason automakers use superchargers from the factory, and it’s the same goal for wrenchers who want to boost their engines’ capacity for horsepower.

Superchargers, like turbochargers, are air compressors that feed oxygen to the engine. As part of the intake stroke, a supercharger pulls and squeezes air into the engine to create that beastly whine. Mobil oil explains the differences between turbocharging and supercharging as such: “Turbochargers use the vehicle’s exhaust gas; two fans–a turbine fan and a compressor fan–rotate from exhaust gas. Conversely, superchargers are powered directly by the engine; a belt pulley drives gears that cause a compressor fan to rotate.”

To really blow your mind, know that a car can be turbocharged and supercharged at the same time. These twin-charged vehicles are rare, but they’re out there.

Supercharger types

Superchargers were invented back in the late 1800s; prolific German inventor Gottlieb Daimler received a patent for supercharging an internal combustion engine in 1885. Today, there are basically three types of superchargers: roots, twin-screw, and centrifugal.

Superchargers have been around 150 years, and they keep improving. Image: Dodge

The roots version, which uses two rotors to push high-volume air into the motor then compressed into the manifold, is the kind you might see poking out of a hood at a hot rod show. Twin-screw is an evolution of the Roots brothers’ design, using specific rotor shapes to compress air as the rotors turn. And centrifugal superchargers look like their turbocharger cousins, employing a compact, round shape. A centrifugal supercharger uses natural centrifugal energy (which moves away from the center) to force additional oxygen into an engine, increasing airflow to burn more fuel. As a result, the engine can crank out more power.

“Centrifugal superchargers by design tend to be more efficient than more conventional roots style superchargers,” Specialty Equipment Market Association (SEMA) Chairman Kyle Fickler told PopSci. As a family of drag-racing champions, Fickler, his daughter Danika, and his wife Debra are bona-fide speed and power experts. 

Fickler also works with ProCharger, which manufactures superchargers. The company advertises a 215-horsepower gain for a 6.4-liter engine with one of its centrifugal superchargers, or a 160-horsepower boost when working with a 5.7-liter Hemi. In essence, what the company is selling is the option to transform a lower-trim Dodge Challenger into a Hellcat for a lower price. A Challenger SRT Hellcat sticker price might top $80,000, so it’s cheaper to add a supercharger to a lower-priced model for about $7,000. For those comfortable tinkering with their engine setup, it may sound like a no brainer.

Not just for muscle cars

Sure, superchargers can boost speed, but that’s not their only function. A supercharger is a cost-effective and smart way to add power to a truck to improve towing and hauling capability as well. 

Ford figured that out with its F-150 Raptor R, which boasts a 5.2-liter supercharged V8 engine delivering 700 horsepower and 640 lb.-ft. of torque. It’s quick from the start, and it can also catch air while bolstered by high-end Fox shocks. The brand says it recalibrated the Raptor R’s supercharger, installing a new pulley to increase torque delivery at the low-end and mid-range and increase off-road power. It also augments the truck’s towing power up to 8,200 pounds.

Boosting power isn’t out of the question for sedans, either, but they’re going electric. Genesis uses a 48-volt mild-hybrid paired with an electric supercharger in its sleek G90 sedan, as does Audi’s S7. In these cases, the supercharger allows the twin turbos to build turbo boost pressure, eliminating that pesky turbo lag that can delay acceleration. 

Whether you’re starting with a factory-installed supercharged engine or an aftermarket add-on, these compressors contribute a lot more than hot air. And the delicious sound of a whining supercharger is a bonus.

Solar cars exist. The best place to see them is the World Solar Challenge, a race that’s held every two years in Australia. Competitors have to drive about 1,870 miles (3,000 kilometers), from Darwin on the country’s north coast to Adelaide on its south coast, using only energy from the Sun.

Many cars that compete in this race look more like amusement park rides or science fiction vehicles than the cars you see on the road. That tells you something about why solar cars aren’t an option for everyday travel, at least not yet.

Collecting enough sunlight

While a lot of sunlight falls on Earth during the day, the light becomes scattered as it travels through the atmosphere, so the amount that hits any given surface is fairly low. Averaged out over a full year to remove the effects of different seasons, it’s about 342 watts per square meter, an area equivalent to about 10 square feet. That’s approximately enough power to run a standard refrigerator.

Car sizes vary a lot, but a full-size car in the U.S. is about 18 feet long and 6 feet wide, so it has about 100 to 110 square feet (9 to 10 square meters) of horizontal surface. That would collect roughly 3,420 watts–enough to run a refrigerator, a dishwasher and a microwave oven.

Large solar farms that send electricity to cities and towns compensate for the fact that sunlight is spread across such a large area by putting up millions of solar panels across thousands of acres. Some, mainly in desert areas, use fields of mirrors to concentrate the Sun’s energy. But a standard car doesn’t have enough surface area to collect a lot of solar energy.

Turning sunlight to energy

Another issue is that today’s solar panels aren’t very efficient at converting sunlight into electricity. Typically, their efficiency is around 20%, which means they convert about one-fifth of the solar energy that reaches them into electric current.

This means that 3,420 watts of solar power falling on an average car covered with solar panels would yield only about 684 watts that the car could use. In comparison, it takes about 20,000 watts for an electric vehicle to drive at 60 miles per hour (100 kilometers per hour).

Vehicles that compete in the World Solar Challenge tend to be large and have designs that maximize their horizontal surface area. This helps them collect as much sunlight as possible. As a concept vehicle, that’s fine, but most models don’t have many windows, or space for anything except a driver.

Highlights from the 2023 World Solar Challenge show that solar cars are designed very differently from conventional models.

When the Sun doesn’t shine

Yet another challenge is that geographic locations, daylight hours and weather conditions all affect how much solar energy can be generated.

The Earth is tilted on its axis, so not all areas receive equal amounts of sunlight at any given time. When the Northern Hemisphere tilts toward the Sun, the upper part of the globe gets more Sun exposure and observes spring and summer, while the Southern Hemisphere is colder and darker. When the southern half of the planet tilts toward the Sun, areas on Earth’s southern half get more Sun and the upper half gets less.

Areas near the equator get consistent sunlight year-round, so zones closer to it–such as Southern California or the Sahara desert–have more intense solar power than places closer to Earth’s poles, such as Alaska.

Solar cars would also struggle to collect enough sunlight on overcast or rainy days. Even big utilities with huge solar farms have to plan for times when the Sun doesn’t shine.

And drivers need their cars to operate at night. In order for a solar car to run after dark, it would need to use extra energy that it collected during the day and stored in a battery. Solar panels and batteries increase the weight of the car, and heavier cars need more power to run.

Researchers are working to design solar cars that are more suitable for everyday use. For this to happen, designers will need to make solar panels more efficient at converting sunlight to energy and design solar panels that are more suitable for cars. It also will be critical to make solar systems for cars cheaper, so average buyers can afford them.

For now, the closest option to a solar car is an electric vehicle that’s charged at home or at a charging station. Depending on how that electricity is generated, some of the energy that flows into these cars is likely from solar panels, wind turbines, hydropower dams or other renewable sources. And that share will rise as states work to switch to clean energy over the next several decades. If you’re driving or riding in an electric car, you might be traveling on solar power right now.

How BMW’s color-changing cars work https://www.popsci.com/technology/bmw-color-changing-cars/ Mon, 01 Apr 2024 17:04:00 +0000 https://www.popsci.com/?p=608830

Lessons from the i5 Flow Nostakana project could help the electronic ink go mainstream.

In 2022, BMW revealed an SUV with color-changing “paint” as a concept, and it created a lot of buzz. The German automaker took its knowledge of electronic ink and ramped it up a notch last month with the i5 Flow Nostokana, an art car wrapped in multicolored, electronically controlled panels.

Distinguished South African artist Esther Mahlangu inspired the i5 Flow Nostokana with her Ndbele designs, typically found in South African provinces Limpopo and Mpumalanga. More than three decades ago, Mahlangu painted her art directly on an all-white 525i, and BMW engineer Stella Clarke never forgot how it looked. It inspired Clarke to put together color-changing panels with Mahlangu’s art for one unforgettable vehicle.

Cars that change color

Electronic ink offers more than just the whiz-bang of rippling color changes on a car. Sure, the possibility exists for drivers to choose the color of the car’s exterior. However, it can also be used to display information on the exterior of the car (think tire pressure or battery levels, for example) or even as a location aid. Imagine, for instance, you can’t find your car in a crowded parking lot. With an app, you could signal the car to flash so you can find it, a better option than flashing the headlamps alone, especially if you’re not within range.

BMW’s Stella Clarke played a critical role in bringing e-ink technology to the automaker, leading the application of e-ink panels to an all-electric iX crossover. About a year ago, Clarke attached some e-ink panels to the outside of a car to showcase the technology internally, and BMW executives were “seriously excited,” she says. There were challenges to overcome, including making the inflexible e-ink-carrying polyethylene terephthalate (PET, as in plastic bottles) sheets wrap around complex curves.

The result was a special project called iX Flow, which was unveiled at the massive Consumer Electronics Show in 2022. Shimmering in white and black, the iX Flow showed how the exterior could change with the touch of a button. It’s easy to imagine the iX Flow in a sci-fi action movie, evading the bad guys by flipping the color.

1,349 e-ink panels, all with color-changing capabilities

Clarke studied mechatronics at the University of New South Wales, then went to Pennsylvania State University on a scholarship. She followed with a research doctorate (Telecontrol of Robots with Haptic Input Devices) at the Technical University of Munich. As reported by Australian Financial Review magazine, Clarke pulled apart her Kindle e-reader one day, and started to wonder if the same technology–e-ink–could be used in a car’s interior.

She received a grant from BMW to find out.

The first thing she noticed was that e-readers (like a Kindle) are rectangular, as are the e-ink panels. Adhering and shaping 1,349 sections of film to the curved surface of a car was challenging, Clarke says, requiring “origami” and laser cutting for a form fit. They don’t stretch, and they’re not malleable.

“It took us a long time to figure out how to get them flexible and [fastened] on the car,” she remembers.

Taiwan-based company E Ink, which provides the technology for its ePaper film, brings together the chemistry, physics, and electronics together using a process called electrophoresis. Each piece of electrophoretic film contains several million microcapsules that are the diameter of a human hair. Each capsule contains differently charged white, black, or colored particles that become visible when an electric field is applied. It’s like color-changing paper, Clarke says.

Each panel needs an electrical signal from a controller, which sends out the voltages that will lead to a certain color. The nice thing about the film panels is that they are bistable, Clarke explains; they require only about 20 watts, and don’t need additional energy to hold a color once the voltage is applied. 

BMW in-house makers 

Currently, all of the controllers that send the signals to the e-ink panels are built in-house by BMW, all custom work.

“We are a group of makers,” Clarke says. “It’s a dream. It’s such a cool project.”

The engineer can see color-changing cars going mainstream; the benefit of bistability is enough to warrant it going further, she says. And the team has learned a lot since the first e-ink project, which Clarke describes as “very much prototype-y.” Previously, they spent their time creating with less planning. For this 2024 project, Clarke estimates they allocated three full-time engineers who planned and discussed how to make it for about four months, and then spent two months putting it all together. 

It has been a revelation for Clarke, who is an engineer at heart and saw the intersection of engineering and art to create something unique and beautiful. Getting a major automaker to buy into a project that would eat up the time of its engineers could have been a tough sell, but Clarke saw the potential. 

“Getting innovation through is not always easy, and it’s often met with skepticism,” Clarke emphasized. “Don’t give up on your ideas.”

The 2024 Bentley Continental GT’s thermal imaging camera is fascinatingly fun https://www.popsci.com/technology/bentley-thermal-imaging-camera/ Sun, 31 Mar 2024 12:03:00 +0000 https://www.popsci.com/?p=608393

The camera can highlight objects you might not see with the naked eye.

A quick way to sum up the $350,000 Bentley Continental GT coupe is that it’s perception-warping. Sticker shock aside, it’s strange rolling around in something so big, luxurious, and supple, yet also has the ability to rip through a twisty road as capably as a sports car half its size. The Conti’s level of athleticism is not something you’d expect in something that weighs more than 5,000 lbs.

And yet, the warping doesn’t stop there. The new car market has made advanced driver assistance—like lane-keep assist and blind-spot monitoring—a commonplace for a few years. But recently, I experienced a whole other form of driver assistance offered in the Bentley Continental GT that I never had before: thermal imaging. And I found it truly fascinating. 

This technology paints what we see in an entirely different light, and was fun to test while cruising around the streets of Los Angeles in peak opulence. Here’s how the British automaker’s thermal imaging system works, what it’s like to use, and how it could affect our concept of safety (for better or for worse).

Night Vision: A fitting proper noun

Bentley calls its thermal imaging system Night Vision, which is fitting since thermal imaging is common in some forms of conventional night vision systems. Fun coincidence: Bentley calls my test car’s silver color Moonbeam.

Thermal imaging is, simply put, a camera with sensors that pick up infrared light, or heat, from the electromagnetic spectrum and turn it into an image. On the flipside, conventional cameras and the human eye create images from visible light. It’s not entirely new, and has been in high-end luxury cars, but this was my first thorough interaction with the technology.

The image broadcasted on Bentley’s 12.3-inch instrument cluster is monochromatic—sorry, no room for Predator references here. The brighter the white light, the hotter it is. The camera is mounted behind the front grille and presents a 24-degree view of what’s ahead, all the way to 300 meters (984 feet), which is over a city block. The Conti isn’t the only Volkswagen Auto Group product with thermal imaging–it’s also offered on other Bentleys, high-end Audis, and the Lamborghini Urus SUV. 

Since it’s thermal imaging, it doesn’t have to be nighttime to see what the camera’s picking up, and also goes a step further by highlighting pedestrians and cyclists that pass through its field of view. Though, the system didn’t pick up someone who wheeled past on a hoverboard scooter—which is either due to lacking a software update, or sharing its own opinion of such contraptions.

Wow, that’s a hot wall over there

As far as how it changed my perception, Night Vision did a number on the way I took in the world around me. It was cool to be behind a car with lots of bright light beneath it—indicating a hot exhaust system—but then change lanes and sit behind a Tesla that had barely any heat signature underneath it at all. Then, no matter the vehicle, it was cool to see traction at work in the form of brightly painted tires. It brought a new form of entertainment to sitting in excruciating traffic on California’s 110 freeway.

Another night, while on some local streets, I became fascinated with the most random things’ heat signatures. Different types of cars, houses, walls: It was a whole new world. While sitting at a stoplight in the neighborhood of Silver Lake, I said out loud, by myself, “Wow, that’s a hot wall over there.” The wall’s heat signature was significantly more pronounced than any other around it, possibly due to its color and the fact that it was facing west. Never thought I’d ever utter such a peculiar statement.

Then, while on a dark, desolate street in Beverly Hills where street lights were few and far between, the Bentley’s system highlighted a jogger far down the way who was nearly invisible to the naked eye, even with headlights illuminating the path ahead. Cool stuff for sure.

Truly helpful?

Despite my wonderment, I can’t help but wonder whether thermal imaging is truly helpful. There’s already a lot of tech in new cars that steals our gaze away from what lies ahead, like tapping screens to navigate through increasingly expansive infotainment systems. And because thermal imaging is so fascinating to use, you can’t help but look at it a bit longer than a quick glimpse to check your speed.

Still, it did come in handy: The fact that it highlights pedestrians and cyclists—which could be a quick glance down as opposed to a long stare—definitely makes up for its ability to be a gaze-stealer. And for anyone who parks one in their garage, the neatness would probably wear off after a while anyway. Even if they too happen to have a new-found curiosity for figuring out the reason behind random walls’ heat signatures.

NYC takes first step towards unleashing robotaxis on city roads https://www.popsci.com/technology/nyc-robotaxis-driverless/ Thu, 28 Mar 2024 18:05:50 +0000 https://www.popsci.com/?p=608514

The United States’ most populous city could soon have scores of autonomous vehicles (AVs) jockeying their way through bustling streets but they will have to do so with a human sitting behind the wheel. After years of relatively subdued AV testing, New York City this week announced new safety requirements and permitting guidelines for companies looking to test their self-driving cars on public roads. NYC’s new guidelines signal a push toward more AV testing and, eventually, deployment while simultaneously putting in place various guardrails to try and avoid replicating recent missteps in other cities

How will AV testing work in the Big Apple?

AV companies approved for testing in New York will need to have a safety driver behind the wheel ready to take over at all times. This approach notably differs from cities like Phoenix, which have already let Alphabet-owned Waymo to test “rider only” trips on city streets. The NYC permit documentation does not mention any specific autonomous vehicle makers by name, but says only companies with past testing in other cities would be considered. Safety drivers will be required to have a driver’s license, complete background checks, prove they have adequate training in the vehicles they are testing, and take frequent breaks to avoid distraction or fatigue. 

Companies looking to test in the city will have to comply with all local traffic laws and pay any traffic or parking tickets the vehicle may incur. Permits will last for one year with the option for renewal at the end of the test period. Any company applying for a permit will also need to provide proof of at least $5 million in car insurance for any autonomous vehicles testing on NYC highways, as well as a $3 million in personal liability insurance. New York’s Department of Transportation, in a statement, says it will work with AV applicants to ensure testing “does not unduly impede traffic flow, pedestrian and cyclist movement, transit service, or emergency response.”

“We are doing our due diligence to get ahead of the AV revolution, and ensure that if AVs are coming, they do so within a framework that benefits New Yorkers, and creates training and good, upwardly mobile jobs in the autonomous industry,” NYC Deputy Mayor for Operation Meera Joshi said in a statement. “It’s been the story for too long that government can’t keep up with private enterprise. No longer.”

NYC Mayor Eric Adams, who made adoption of AI technology a priority during his administration, echoed that sense of inevitability. 

“This technology is coming whether we like it or not, so we’re going to make sure that we get it right,” Adams said in a statement. “If we do, our streets can be safer, and our air could be cleaner.” 

The new permitting process marks a pivot point for NYC. Up until now, AV testing hadn’t gained traction to the same degree as other large US cities like San Francisco and Phoenix. General Motors backed Cruise planned to test its vehicles in the city’s back in 2017 but eventually backtracked. Waymo, on the other hand, begun some testing in the city but has reportedly focused primarily on areas of upstate New York. 

Driverless vehicles will still have to overcome numerous roadblock for adoption in NYC 

Companies looking to commercialize AVs in NYC still face an uphill battle even with the city’s renewed interest in testing. New York’s mix of pedestrian-filled streets, unpredictable vehicle traffic, and sensor disrupting bright lights make it one of the most challenging environments for AVs to navigate successfully. Driverless vehicles have made notable improvements on highways but their effectiveness degrades as they enter more complex, densely populated urban areas. NYC’s DOT itself called the city the “country’s most challenging urban environment.”

Aside from technical challenges, AVs may also face pushback from labor groups and local drivers. The Teamsters previously spoke out against Waymo’s efforts to expand AV testing in the state, calling the technology a “direct threat to public safety.” Two organizations representing New York taxi-cab drivers previously called for legislation banning driverless cars outright in the city. Two third of drivers, recently surveyed by AAA Western and Central New York, meanwhile, said they were afraid of driverless vehicles. 

“There has been an increase in consumer fear over the past few years,” AAA Director of Automotive Engineering Research Greg Brannon said in a statement. “Given the numerous and well-publicized incidents involving current vehicle technologies–it’s not surprising that people are apprehensive about their safety.”

Still, supporters of the push for more autonomous vehicles like mayor Adams believe the technology could one day improve safety by cutting back on human error-induced accidents. Supporters hope large scale autonomous vehicle rollout, when paired with improved mass transit, could also potentially cut down on traffic. Electric powered AV robotaxis could also theoretically lead to less emissions than internal combustion alternatives, especially if they are used to transport more than one person at a time.

New York’s new AV approach comes amidst a thawing interest in driverless vehicles nationally. Multiple crashes and missteps by Cruise in California last year resulted in the company losing its ability to operate in the state. Local officials in Austin, once an early adopter in AV’s testing, are now questioning the safety of driverless cars. High profile accidents involving AVs are appearing to impact public perceptions of the vehicles. A study of US drivers conducted in 2023 by J.D. Power found driver trust in self-driving vehicles declined for the second year in a row.

Maserati Grecale Folgore first drive: A luxury electric SUV that was worth the wait https://www.popsci.com/technology/maserati-grecale-folgore-first-drive/ Tue, 26 Mar 2024 17:03:00 +0000 https://www.popsci.com/?p=607972

The first full-electric Maserati SUV: Grecale Folgore. Maserati

The 2024 Maserati Grecale Folgore is the fulfillment of a pledge. When the luxury vehicle manufacturer introduced the Grecale crossover SUV two years ago, it promised a battery-electric version in the future.

The Grecale Folgore was worth the wait. No gas-powered model can match the silence and smoothness of the Grecale Folgore. The effortless power is delivered by its front and rear, which each contribute 279 horsepower for a total of 558 horsepower. 

This vaults the Folgore (Maserati applies this label to the EV versions of its cars) to 62 mph (100 kph) in 4.1 seconds, despite the car’s 5,456-lb. curb weight. Top speed is rated at 138 mph, which is obviously plenty, even if it doesn’t live up to Maserati’s legendary speed capability. Blame ‘70s rocker Joe Walsh for his “My Maserati does 185, I lost my license, now I don’t drive” lyric for the inflated expectations.

A need for (charging) speed

But the Grecale is speedy in a specification that is more relevant in the age of electric cars: charging. Its DC fast-charging speed is a conventional 150 kilowatts, which is supported by many public charging stations. This will bring the car’s 105-kW 400-volt battery pack from a 20 percent state of charge to 80 percent in less than 30 minutes.

The unexpected part is that the Grecale Folgore’s on-board charger–the one that handles AC current from your home wall box or from Level 2 AC public charging stations–can handle 22 kW, which is double the current level that most EVs top out at.

My own ChargePoint home charging station tops out at 9.6 kW. But Maserati will provide Grecale owners with a 22-kW box for their homes to support the vehicle. Users will need the box to deliver that much power from their home’s electrical system, which may require extra work by electricians. It will be worth the extra effort, as it should top off the battery in less than five hours–instead of the more typical nine hours. When you charge overnight, the difference won’t matter. But for mid-day top-offs between errands or carpool runs, it can ensure the Grecale preserves its driving range.

Maserati says that the SUV will go 310 miles on a charge. During a test drive in southern Italy, my test car’s computer predicted a driving range of 290 miles with a 96 percent charge, which is slightly less than the company’s rating. But the cool morning air can reduce range estimates as the car heats the cabin.

Testing different drive modes

That drive also revealed the Grecale to be comfortable and nimble, with lively, accurate steering and handling. This is a contrast to the Rivian R1S with its relentlessly harsh ride, even though the Maserati rolled on 21-inch wheels, nearly as large as the Rivian’s 22s. Large wheels contribute to a harsh ride because their low-profile tires have less rubber sidewall between the wheel and the road surface to absorb bumps.

Computer-controlled air suspension, which is optional on combustion-powered Grecales, is standard on the Folgore to help provide expected levels of ride and handling despite the mass of the battery pack weighing the car down. The suspension is controlled by Maserati’s Chassis Domain Control Module (CDCM), just like the one in Maserati’s MC20 super sports car. Maserati says that the system operates predictively, rather than reactively, to control movement in the vertical, longitudinal, and lateral axes.

That suspension bolts to a frame that is made of three large-scale aluminum castings rather than stamped sheets of steel. Tesla has pioneered this manufacturing approach, which eliminates hundreds of parts that must be connected together and replaces them with a handful of castings. The technique simplifies assembly and provides a rigid platform for the suspension (but we have yet to learn the implications for crash repairs in case of an accident).

The Grecale Folgore offers multiple selectable driving modes: Max Range, GT, Sport, and Off-Road. The Off-Road mode raises the vehicle on its suspension for added ground clearance. Maserati wisely skipped providing an off-road course for testing, which makes sense given that the car’s buyers can’t really be considering taking it off-roading with any regularity.

Instead, I focused on the on-road driving dynamics. I found that the Max Range, GT, and Sport modes each have different feelings, as they increasingly speed up the power delivery. That means the accelerator pedal gets touchier as you work up the range. Correspondingly, while holding the pedal still, you can see the Grecale’s energy consumption increase significantly when switching from Max Range to GT and then to Sport.

Unlike some vehicle accelerator pedals that seem to go limp and become unresponsive in the maximum range mode, the Grecale still drives like a Maserati, even in that least-sporty setting. 

Inside the recycled interior

The Grecale Folgore retains the steering wheel-mounted shift paddles of the combustion-powered models, but repurposes those paddles to let the driver adjust the levels of brake regeneration. Maserati’s engineers have done a good job calibrating the regeneration so that it feels natural and the switch-over to the friction brakes as the vehicle comes to a stop is not discernible.

The 12.3-inch center-mounted infotainment display supports wireless Apple CarPlay and Android Auto, and there’s a wireless charging pad at the base of the dashboard. The virtual analog clock in the circular display at the top of the dashboard switches briefly to show a lightning bolt to confirm that your phone is charging.

In keeping with its green perspective, the Grecale Folgore uses recycled nylon for its upholstery. This fabric is Aquafil’s ECONYL, which is made using nylon recovered from recycled carpeting and fishing nets. Compared to other recycled plastics, nylon has the advantage of being able to be chemically recycled instead of mechanically recycled. 

This means that the recycled material is indistinguishable from nylon made from petroleum, according to Aquafil sustainability communications practitioner Martina Santoni. Because of this trait, nylon can be recycled repeatedly, in true circular economy fashion, she says. “Circularity is the only solution possible in every sector,” Santoni insists.

While the Folgore’s aims are green, the electric model’s signature color is a coppery matte hue called Rame Folgore, which is meant to evoke the copper used in the EV’s wiring. It has the appeal of being unique and interesting.

The same could be said for the Grecale Folgore itself. Driving a Maserati might not be every EV buyer’s preference, but those who do choose it will appreciate its classically Italian style combined with a modern focus on efficiency.

Just last year, Italian supercar builder Lamborghini launched its first plug-in hybrid. The Reveulto’s system combines a new V12 gas-powered engine and three electric motors for an impressive 1,001 horsepower and more than 800 pound-feet of torque, claiming the title of “most powerful plug-in hybrid on the market.”

Now the brand is taking its hybrid experience to the motorsport circuit with the SC63 hypercar, an electrified race car that harnesses the power of a 3.8-liter twin-turbo V8 and pairs it with a 50-kilowatt Bosch electric motor. Lamborghini is no stranger to the motorsport circuit, enjoying 15 years of success with its Huracan GT3 race car, but 2024 is the first time it is entering the FIA World Endurance Championship and International Motor Sports Association prototype categories.

Historically, founder Ferruccio Lamborghini thought racing was a waste of time and money; he believed he didn’t need motorsports to prove his cars’ worth. It’s a different game today, Lamborghini CEO Stephan Winkelmann told Car and Driver.

“The trends are changing, and there is a technical reason too,” Winklemann said. “We’re in the midst of transition from ICE to plug-in hybrid. Endurance racing gives us a chance to test materials.”

Plus, he said, seeing electrified systems in motorsports helps customers accustomed to V8 and V12 engines to accept electrified production cars.

A “cold V” and eight radiators

With the completion of the 12 Hours of Sebring Race earlier this month, the Raging Bull has added a big checkmark to its inaugural year of prototype racing. Aerodynamically focused and swoopy, the SC63 hints at its Lamborghini lineage but it doesn’t look like its road-going cars. Per racing rules, the car had to meet size requirements, but chief designer Mitja Borkert incorporated the brand’s unique Y-shaped taillights and an inlet inspired by the air intake of the legendary Countach model.

The V8 was developed specifically for racing by the Raging Bull with a “cold V” configuration, which means the turbos are mounted outside of the V shape of the block as opposed to the inside of the V, a hallmark of a “hot V” setup. This arrangement makes it easier for mechanics to access the turbos to service them, and it offers the additional benefit of facilitated cooling. By placing the turbos on the outside of the engine, the car has a lower mass and makes the most out of its center of gravity. Ultimately, that translates to optimal balance and consistent speed on the track both short and long term.

Managing thermal elements is key during the race, and the prototype features eight different radiators. That includes two intercoolers, which cool compressed air from the turbocharger before it enters the engine, along with radiators for the gearbox, the energy recovery system, energy storage system, and others. All in, the car was built for the worst-case heat scenarios (especially in hot, humid Florida) to be as thermally efficient as possible.

The drivers had a say, too. Lamborghini prototype driver Romain Grosjean has hybrid race experience in Formula 1 and consulted with the engineers to tune the LMDh system and the design of the steering wheel controls.   

The result: More work is needed, but it’s looking good

The SC63 didn’t win the race, but that wasn’t the goal for the supercar brand. Ultimately placing seventh, the Lamborghini race car finished intact, sharing data points and experience the brand will use for future races and even production cars.

“The [race car] is still very specific because it’s really super sophisticated,” Chief Technology Officer Rouven Mohr told Car and Driver. “But the newer damper technology, what we find today in a high-performance car, you have seen some years ago in the race cars: multi-way adjustability, friction optimization. This, by the way, is something that we learned also on the [race cars], to minimize every friction in your suspension. This is something that you can use for the street car, even if you are not carrying over the suspension itself.”

Grosjean says he is happy with the result, especially knowing that the Sebring 12 Hours is one of the toughest races out there due to the bumpy, uneven surface of the track. “It is a really positive step that we managed to finish the race and on the lead lap in P7,” Grosjean says. “There is still a lot that we need to work on, and I am excited for the future.”

Mohr shares his enthusiasm and agrees the brand can take its learnings from Sebring and apply them for improvements.

“I am delighted with the result of the #63; finishing seventh and on the same lap as the winner of the race is an incredible achievement,” Mohr says. “Of course, there are always things to do better, and we are aware that we need to close the gap to the front of the field, which is still quite far away at the moment.”

EPA says over half of all new cars must be EVs or hybrids by 2032 https://www.popsci.com/environment/epa-car-pollution-standards/ Wed, 20 Mar 2024 17:30:00 +0000 https://www.popsci.com/?p=607265

The Biden Administration’s new policies are the strictest auto pollution regulations yet.

The Biden administration has announced some of the biggest pollution regulations in US history. On Wednesday, the Environmental Protection Agency revealeded the finalization of new, enforceable standards meant to ensure electric and hybrid vehicles make up at least 56 percent of all passenger car and light truck sales by 2032.

To meet this goal, automotive manufacturers will face increasing tailpipe pollution limits over the next few years. This gradual shift essentially means over half of all car companies’ sales will need to be zero-emission models to meet the new federal benchmarks.

According to the EPA, this unprecedented industry transition could cut an estimated 7 billion tons of emissions over the next three decades. Regulators believe this will also offer a nearly $100 billion in annual net benefits for the nation, including $13 billion of annual public health benefits from improved air quality alongside $62 billion in reduced annual fuel, maintenance, and repair costs for everyday drivers.

[Related: EPA rule finally bans the most common form of asbestos.]

Transportation annually generates 29 percent of all US carbon emissions, making it the country’s largest single climate change contributor. Aggressively pursuing a nationwide shift towards EV adoption was a cornerstone of Biden’s 2020 presidential campaign platform. While in office, Donald Trump rolled back the Obama administration’s previous automotive pollution standards applicable to vehicles manufactured through 2025. He has promised to enact similar orders if re-elected during this year’s presidential election.

The EPA’s new standards is actually a slightly relaxed version of a previous proposal put forth last year. To address concerns of both manufacturers and the industry’s largest union, United Auto Workers, the Biden administration agreed to slow the rise of tailpipe standards over the next few years. By 2030, however, limits will increase substantially to make up for the lost time. The EPA claims today’s finalized policy will still reduce emissions by the same amount over the next three decades.

The new rules are by no means an “EPA car ban” on gas-powered vehicles, as lobbyists with the American Fuel & Petrochemical Manufacturers continue to falsely claim. The guidelines go into effect in 2027, and only pertain to new cars and light trucks over the coming years. The stipulations also cover companies’ entire product lines, so it’s up to manufacturers to determine how their fleets as a whole meet the EPA benchmarks.

Still, fossil fuel companies and Republican authorities are extremely likely to file legal challenges over today’s announcement—challenges that could easily arrive in front of the Supreme Court in the coming years. Earlier today, the vice president of federal policy for the League of Conservation Voters said during a press call that they already discussed such possibilities with the Biden administration, and “they are crystal clear about the importance of getting rules out to make sure that they withstand both legal challenges from the fossil fuel industry and any congressional attacks should Republicans take over the Senate and the White House.”

The company's latest EV launch brought a few surprises.

Rivian is having a big moment. Last week, the company launched its new R2 SUV with a starting price of around $45,000 and about 300 miles of range with the larger battery pack. That’s roughly 40 percent cheaper than the brand’s larger three-row R1S, which debuted for model year 2022.

In a surprise move, Rivian unveiled its even-smaller R3 compact hatchback SUV and performance-oriented R3X. Chief design officer Jeff Hammoud told The Drive that the R3’s sloped backside was inspired by Group B rally cars, and its shape is a noticeable departure from the chopped rear of the R1S. Here’s the backstory of what Rivian is up to. 

The new R2… and surprise! An R3

The newest vehicles in the Rivian lineup share a fresh midsize EV platform, which the automaker says reduces the number of parts through consolidation and intelligent design. Both the R2 and R3 will be available with three motor configuration options: single-motor, rear-wheel drive; dual-motor, all-wheel drive; and a three-motor setup with two motors in the rear and one in front.

Less than 24 hours after the launch, more than 68,000 reservations poured in for the R2. It doesn’t hurt that Rivian unveiled a slew of custom accessories for the new EV line, including rooftop tents and other outdoorsy options. The announcement that Rivian models will be able to be charged up at Tesla Superchargers helps as well. Following Ford’s lead, Rivian models can connect to Superchargers with an available adapter that’s about the size of a 1.5-pound bag of coffee beans. And finally, the price tag of less than $45,000 will put the R2 in a competitive bracket with other EVs and will be more affordable for families.  

While it might have seemed like a head-scratcher to some that Rivian upstaged its own R2 reveal to pull the curtain off the R3 and R3X, it’s a move that brings major buzz to a scrappy EV brand looking for a win. With investing analysts giving Rivian middling marks recently as EV demand appears to wane, the EV builder is looking for all the interest it can generate.

During the reveal, Rivian also announced some key changes to its production plans. Its $5 billion Georgia plant is on pause as the automaker shifts manufacturing back to its Normal, Illinois facility. Rivian purchased the former Mitsubishi plant in 2017 and has been building its vehicles there while it runs most of its corporate operations in California. It also develops software in the Stanford Research Park in Palo Alto and builds motors in Los Angeles, and has other facilities in Plymouth, Michigan; Wittman, Arizona; Woking in the UK; Vancouver in Canada; and Belgrade, Serbia.

All-electric delivery vans shore up Rivian’s revenue

Electric vans are also part of Rivian’s overall plan for success. E-commerce giant Amazon invested $700 million in the brand and ordered 100,000 electric vans developed by Rivian, and while that’s an exclusive relationship currently, expect Rivian to branch out and broaden its portfolio. 

“While investors may have been focused on the over 68,000 R2 reservations in less than 24 hours after the unveiling, one of the company’s most critical stories will revolve around its electric van,” reported The Motley Fool. “That’s simply because not only is Rivian still set to deliver 100,000 vans to Amazon by 2030, the ending of their exclusive partnership opens the door for similar customers.” 

Rivian has produced solid vehicles over the last few years, providing an EV with better build quality than rival Tesla. During the grueling eight-day off-road Rebelle Rally competition, a pair of Rivian engineers took home the win in the middle of the desert in a Rivian R1T. Powered by a solar- and hydrogen-powered mobile truck, the R1T didn’t have any range challenges and proved its mettle.

Now we’ll see if the brand can scrabble its way toward profitability with two new models and more on the way.

‘Safe’ driver assist tools could be doing more harm than good https://www.popsci.com/technology/driver-assist-features-safety-concerns/ Wed, 13 Mar 2024 19:00:00 +0000 https://www.popsci.com/?p=606448

A first-of-its-kind safety report testing advanced driver assistance systems suggests carmakers aren’t doing enough to prevent driver abuse and misuse.

The post ‘Safe’ driver assist tools could be doing more harm than good appeared first on Popular Science.

Drivers in the US and around the world are increasingly interested in getting behind the wheel of new vehicles capable of automatically changing lanes and maintaining speeds on highways. Carmakers argue vehicles equipped with these partially autonomous tools, collectively referred to as advanced driver assistance systems (ADAS) are a win-win, offering drivers both convenience and added safety, especially during long trips where fatigue sets in. ADAS, in other words, can cut back on human error. 

But a first-of-its report on ADAS systems from The Insurance Institute for Highway Safety (IIHS), one of the nation’s leading independent safety groups, questions whether or not these tools are actually improving safety at all. The IIHS tested ADAS systems from 14 separate carmakers and not a single one of them earned its highest “good rating,” while 11 of the systems received a “poor” rating. The striking IIHS results highlight the importance of rigorous testing to ensure highly-marketed ADAS are actually being used the ways they are advertised and not unintentionally causing more harm than good.  

“Some drivers may feel that partial automation makes long drives easier, but there is little evidence it makes driving safer,” IIHS President David Harkey said in a statement. “As many high-profile crashes have illustrated, it can introduce new risks when systems lack the appropriate safeguards.”

What are ADAS systems?  

Vehicles equipped with ADAS systems use onboard cameras and sensors to analyze roadways and help keep drivers, maintain proper speeds, and automatically apply brakes when appropriate. Some of these systems, like Tesla’s popular Autopilot and Full-Self-Driving, can also automatically switch between lanes. Systems like these are growing in popularity. Counterpoint Research estimates ADAS enabled vehicles made up 46% of new cars sold in the US in the first half of 2022. 

Despite confusing branding from some automakers and others that may suggest otherwise, ADAS systems crucially are not the same as fully-autonomous, self-driving vehicles. Cars with automated driver systems are rated on an six-point autonomy scale ranging from 0-5. Autopilot, for example, is considered Level 2 whereas more advanced driverless systems that do not require a driver, like the one being pursued by Waymo, are considered Level 4. Drivers using partial automated driving systems are still legally required to monitor their vehicle and be prepared to take over control at a moment’s notice.

[Related: Researchers propose fourth traffic signal light for hypothetical self-driving car future]

The IIHS report, which tested systems from BMW, Ford, General Motors, Genesis, Lexus, Mercedes-Benz, Nissan, Tesla, and Volvo, pushes back on whether these ADAS systems are actually making roads safer. Most of the systems analyzed by the IIHS failed to properly determine whether or not a driver was looking at the road or lacked attention reminders to prevent drivers from being distracted. In some cases, the IIHS says drivers can activate some of the systems without ever strapping on a seat belt. 

In order for ADAS systems to be considered safe, IIHS says they must be able to consistently detect whether or not a driver’s eyes are facing the road and if their hands are on the steering wheel. This is often accomplished through front facing in-cabin cameras and steering wheel sensors. None of the 14 systems adequately met these requirements. In some cases, in-car cameras failed to react when they were partially obscured. The Mercedes-Benz system, meanwhile, lacked an in-car camera altogether. 

When drivers aren’t keeping their eyes on the road, the IIHS says ADAS systems should send out visible and audible alerts within 10 seconds, and initiate an emergency slowdown system within 20 seconds. Seven of the tested systems failed to provide these “dual-mode” alerts within 15 seconds. Two of the systems reviewed, one from Tesla and another from BMW, reportedly continued to switch between lanes without a new input form the driver, even after a driver has stopped for more than two minutes. IIHS argues that lack of human input over prolonged periods of time can dangerously “discourage drivers from being physically involved in the driving.” 

The IIHS similarly looked at how these systems responded when a driver failed to respond to a warning for more than 35 seconds, a key sign the driver is either incapacitated or willfully abusing the system. In this scenario, the IIHS says the vehicles should automatically begin an emergency slowdown and alert local emergency services. General Motors’ Super Cruise system was the only ADAS product tested that met those specifications. 

“Most of them don’t include adequate measures to prevent misuse and keep drivers from losing focus on what’s happening on the road,” Harkey added. 

Preventing “intentional misuse”  

Leading carmakers have, for years, used IIHS safety ratings in other areas as selling points for their vehicles in advertisements and other promotional materials. Founded in 1959 by three leading insurance associations, the IIHS describes itself as a “nonprofit scientific and educational organization” focused on reducing car injuries and damage. The IIHS reportedly decided to make this ADAS rating system in part because the National Highway Traffic Safety Administration, the nation’s leading auto regulator, currently lacks any comparable standards. 

IIHS hopes these new ratings will pressure carmakers to take more steps to prevent “intentional misuse” of these ADAS systems by drivers. Similarly the IIHS wants to discourage carmakers from letting users activate these systems when automatic braking and seat belts aren’t on. Many of the  safety issues described by the IIHS are potentially addressable via over-the-air updates, which carmakers can ship without ever requiring a driver to bring their vehicle into a dealership. 

“No single system did well across the board, but in each category at least one system performed well,” Harkey added. “That means the fixes are readily available and, in some cases, may be accomplished with nothing more than a simple software update.”

Rigorous testing of ADAS systems’ reliability are crucial as they become more widely used and, inevitably, become involved in more crashes. As of 2022, the NHTSA estimates ADAS systems were active during at least 392 crashes in the US, which resulted in around half a dozen deaths. 367 of those incidents were reported in just the 10 months between July 2021-May 2022. Tesla, due in part to the popularity of its ADAS systems, accounted for the vast majority of the overall reported crashes. 

Those challenges notwithstanding, drivers still repeatedly show more interest in ADAS systems than their more advanced, driverless older sibling. A spat of accidents and missteps from autonomous vehicles maker Cruise in California resulted in them having to halt operations in the state indefinitely. Elsewhere, public officials in cities like Austin, once warm welcomes of self-driving vehicles, have pushed back against the idea of these vehicles operating without safety drivers. And drivers are still on the fence about whether or not fully driverless vehicles are even desirable. Almost half of  US adults surveyed by Pew in 2022 said they thought widespread driverless cars would be bad for society. 

ADAS, by contrast, has grown in popularity. And while some studies have suggested these automated features could meaningfully cut back on accidents and serious injuries, those proposed benefits only make a real difference if the systems aren’t being abused or misused. Independent testing of ADAS systems can pressure carmakers to quickly fix blind spots in their driver monitoring and attention safeguards, which could cut back on inappropriate uses of the technology. At the same time, carmakers will have to carefully consider the steps they take to enforce those safety standards to avoid alienating drivers who may feel uncomfortable with their cars collecting ever-greater amounts of potentially sensitive data about them.

Fully self-driving cars, despite the claims of some companies, aren’t exactly ready to hit the roads anytime soon. There’s even a solid case to be made that completely autonomous vehicles (AVs) will never take over everyday travel. Regardless, some urban planners are already looking into ensuring how such a future could be as safe and efficient. According to a team at North Carolina State University, one solution may be upending the more-than-century-old design of traffic signals.

The ubiquity of stop lights’ Red-Yellow-Green phases aren’t just coincidence—they’re actually codified in an international accord dating back to 1931. This has served drivers pretty well since then, but the NC State team argues AVs could eventually create the opportunity for better road conditions. Or, at the very least, could benefit from some infrastructure adjustments.

Last year, researchers led by civil, construction, and environmental engineering associate professor Ali Hajbabaie created a computer model for city commuting patterns which indicated everyday driving could one day actually improve from a sizable influx of AVs. By sharing their copious amounts of real-time sensor information with one another, Hajbabaie and colleagues believe these vehicles could hypothetically coordinate far beyond simple intersection changes to adjust variables like speed and break times.

To further harness these benefits, they proposed the introduction of a fourth, “white” light to traffic signals. In this scenario, the “white” phase activates whenever enough interconnected AVs approach an intersection. Once lit, the phase indicates nearby drivers should simply follow the car (AV or human) in front of them, instead of trying to anticipate something like a yellow light’s transition time to red. Additionally, such interconnectivity could communicate with traffic signal systems to determine when it is best for “Walk” and “Do-Not-Walk” pedestrian signals. Based on their modeling, it appeared such a change could reduce intersection congestion by at least 40-percent compared to current traffic system optimization software. In doing so, this could improve overall travel times, fuel efficiency, and safety.

[Related: What can ‘smart intersections’ do for a city? Chattanooga aims to find out.]

But for those concerned about the stressful idea of confusing, colorless lights atop existing signals, don’t worry—the “white” is just a theoretical stand-in until regulators decide on something clearer.

“Research needs to be done to find the best color/indication,” Hajbabaie writes in an email to PopSci. “Any indication/color could be used as long as it does not associate with any existing message and does not create confusion.”

This initial model had a pretty glaring limitation, however—it did not really take pedestrians into much consideration. In the year since, Hajbabaie’s team has updated their four-phase traffic light computer model to account for this crucial factor in urban traffic. According to their new results published in Computer-Aided Civil Infrastructure and Engineering, the NC State researchers determined that even with humans commuting by foot, an additional fourth light could reduce delays at intersections by as much as 25-percent from current levels.

Granted, this massive reduction is dependent on an “almost universal adoption of AVs,” Hajbabaie said in a separate announcement this week. Given the current state of the industry, such a future seems much further down the road than many have hoped. But while not a distinct possibility at the moment, the team still believes even a modest increase in AVs on roads—coupled with something like this fourth “white” phase—could improve conditions in an extremely meaningful way. What’s more, Hajbabaie says that waiting for fully autonomous cars may not be necessary.

“We think that this concept would [also] work with vehicles that have adaptive cruise control and some sort of lateral movement controller such as lane keeping feature,” he tells PopSci. “Having said that, we think we would require more sensors in the intersection vicinity to be able to observe the location of vehicles if they are not equipped with all the sensors that smart cars will be equipped with.”

But regardless of whether cities ever reach a driverless car future, it’s probably best to just keep investing in green urban planning projects like cycling lanes, protected walkways, and even e-bikes. They’re simpler, and more eco-friendly.

The park's rules protect wildlife–and keep things quiet.

Replete with stunning hydrothermal and geologic features and thriving wildlife across 2.2 million acres, Yellowstone National Park is a national treasure. It’s also America’s first national park; former president Ulysses S. Grant made it official on March 1, 1872.

The national park maintains its beauty with a stringent set of environmental regulations that places the welfare of the park front and center. For example, during the winter months only certain kinds of vehicles and snowmobiles are allowed on the groomed trails, and they must meet the park’s Best Available Technology (BAT) standard for emissions. Only one snowmobile brand currently meets the criteria: Ski-Doo. 

Snowmobile restrictions and regulations in Yellowstone

In 2023, Yellowstone National Park attracted 4.5 million visitors. Summer is the busiest time for Yellowstone, when kids are out of school and families are taking road trips across the country. Winter, however, is more tranquil and quieter. The bears are hibernating, the skies alternate between gray and a surreally saturated blue, and snow blankets the park with perfect crystalline snowflakes.

To navigate the trails once the snow falls, a limited number of snowmobiles and snowcoaches (vans or other vehicles fitted with giant snow tires) are allowed to operate inside the park. Snowmobiles were first permitted inside the gates in 1963 to boost winter attendance, as visitors could see more of the park than they could on foot or cross-country skis; the machines also enabled those with physical limitations. That went on until 1997, when animal rights organization Fund for Animals filed a lawsuit to ban snow grooming on paved roads in the park. Since snowmobiles were only permitted on groomed roads, the ban would have effectively eliminated snowmobile use as well.

Ultimately, snowmobiles remained, but with new safeguards in place for the Yellowstone ecosystem. Through that process, the national park service learned about new emissions technology offered in four-stroke snowmobile engines that decreased carbon emissions by more than 70 percent and decreased sound levels by about half.

As a result, updated regulations today state that snowmobiles entering the park must operate at or below 67 dBA (the measurement of sound levels) and must be certified for certain emissions levels. According to the National Park Service, a snowmobile “will be certified for six consecutive winter seasons following its manufacture or until the snowmobile travels 6,000 miles, whichever occurs later, and model year 2015-2017 snowmobiles must have less than 6,000 miles on the odometer to be approved.”

Ski-Doo’s approved-for-Yellowstone snowmobiles employ a four-stroke engine, which is more efficient and emits fewer toxic fumes than the two-stroke engines offered in other snow machines. The company’s ACE (advanced combustion efficiency) engines are designed with a square bore and stroke in a spherical combustion chamber and tuned to use less fuel to create power. Thus, fewer emissions. YouTube channel driving 4 answers does a great job explaining the difference between two- and four-stroke engines and how they work. 

Of the two Ski-Doo engine configurations allowed at Yellowstone, the 600 ACE is the most fuel efficient with a rating of 28 miles per gallon at 60 horsepower, while the 900 ACE is good for 90 horsepower and gets 21.8 miles per gallon. These are off-the-shelf Ski-Doo engines that anyone can purchase, not just those traveling through Yellowstone National Park. 

“From the get-go, [the ACE engines] were designed to be efficient,” says Steve Cowing from Bombardier Recreational Products (BRP), the company that owns Ski-Doo. “That includes the sizing of the valve, the stroke, the oil pump, and all the tiny little details.”

The future of electric snowmobiles

Ski-Doo’s parent company is aiming for all of its facilities to be carbon neutral by 2030 and for 50 percent of its products to be electric by 2035. Ski-Doo introduced two all-electric sleds last year, but it’s careful to note that they include limited range and are designed for short distances. Range anxiety is the same issue auto manufacturers face as infrastructure ramps up, Cowing says. 

Currently, the electric snowmobile can’t get from West Yellowstone to Old Faithful and back on one charge, so it’s a different experience. And for someone looking to explore as much of Yellowstone’s natural splendor as possible, it’s much less satisfying.

So far, customers who have tested out the new electric sleds are impressed with the performance and power. It’s only the range that’s holding them back, and the brand isn’t anywhere near giving up on electric power. 

“We need to be cleaner and quieter,” says BRP product development manager Frederic Desjardins. “The social perception of our industry is very important to us.”

Snowmobiling through the park allows visitors to see bison, coyotes, fowl, and maybe even wolves from a safe distance, and guides explain the rules of engagement explicitly before starting any tour. Wildlife is to be left alone and never approached for the well-being of both animals and humans. 

Viewing the park from the seat of a snowmobile with heated seats and handlebars is a fun way to see it all within the parameters of safety and ecology, and manufacturers and tour guides are keen to stay within the lines. The area around Yellowstone, including scores of snowmobile guides, hotels, restaurants, and other hospitality depend on the industry to keep up with the standards and keep the park snowmobile-friendly. At the same time, it’s critical that manufacturers keep improving. Desjardin says each snowmobiler he knows loves nature; it’s one thing they have in common with the people who like to walk in the park. 

“Snowmobilers see more nature in one day than most people see in one season or even three seasons,” says Cowing, a snowmobiling enthusiast and 22-year veteran of the industry. “People who live in West Yellowstone and in these parks understand it really well. They really are stewards of the land.”

Green Bank Observatory

The United States National Radio Quiet Zone (NRQZ) is a 13,000 square-mile rectangle covering the southernmost tip of Maryland’s western panhandle, the Allegheny Mountains in Eastern West Virginia, and the Blue Ridge Mountains in Central Virginia. The area exists to protect key government installations deep in the heart of the NRQZ from radio interference, including the Green Bank Observatory in Green Bank, West Virginia. The most severe restrictions exist within a 20-mile radius of the observatory and involve limitations on Wi-Fi and cellular service, and the prohibition of all but diesel-powered vehicles when approaching the observatory itself.

The world’s largest fully steerable radio telescope, the Robert C. Byrd Green Bank Telescope, operates at Green Bank and requires radio silence for its work. The telescope has found everything from a trio of millisecond pulsars from Messier 62 to the most massive neutron star yet discovered, PSR J0740+6620. Such findings are only possible due to the extreme sensitivity this and the other three radio telescopes at the observatory possess. But the drawbacks of these highly sensitive instruments are their ability to detect any radio transmission–from digital cameras, smartphones, or even the spark plugs of gasoline-powered vehicles. Thus, the restrictions imposed.

EVs in the NRQZ

Enter electric vehicles and the infrastructure needed to keep them going. For most parts of the NRQZ–which U.S. Interstates 81, 79 and 64 pass through–EV owners might not even realize they’re within this special part of the U.S. Would such vehicles face similar issues as gas-powered cars deep in the heart of this unique zone due to their electric motors emitting radio frequencies that would interfere with the work performed at the Green Bank Observatory?

“Electric vehicles are on campus,” said Jill Malusky, the news and information manager for the observatory. “Some of our staff have them. We have two charging stations on campus that the public can access. There are also some charging stations in the area. We have a bigger ski resort up here called the Snowshoe Ski Resort about a 45-minute drive [from Green Bank], and they have electric vehicle charging stations up there.”

Malusky adds that Green Bank isn’t as isolated as some reports would suggest; some 50,000 visitors visit the observatory each year to learn more about radio astronomy and the NRQZ. She says all vehicles are welcome onto the public areas of Green Bank Observatory, including EVs. But just like fully gas-powered vehicles, EVs, plug-in hybrids, and regular hybrids cannot approach the 1.5-mile radius surrounding the radio telescopes. The reason is that diesels do not emit as much radio interference as spark plugs and electric motors. Instead, visitors can hike or cycle one of the trails leading into the quietest part of the NRQZ, or board a diesel-powered bus.

However, there is one potential concern still on the ground: the day diesels are potentially phased out of production. As more and more manufacturers push to go fully electric, it may not be too long afterwards until the parts needed to keep the diesels at Green Bank going are harder to track down. What happens then?

“When we are doing maintenance, we tend to turn our biggest telescope off,” said Mulasky. “We already most of the time turn everything off, anyways; we can’t observe while maintenance is happening. So, we would just do it like that. We would just shift the way that we do maintenance, turn everything off, plan accordingly, and then get those electric vehicles out of the way when they’re done, turn everything back on.”

Who lives in the Quiet Zone?

Then, there’s Green Bank itself, a small census-designated community of 200–including many employees with the Green Bank Observatory–with a public library, a fire department and an elementary school. Mulasky says that many of the stories about the community and its relationship with modern technology is a complex tale.

“Hundreds of thousands of people live in the Quiet Zone and don’t realize it,” said Malusky, “because of the way the Quiet Zone works in those parts only really impacts industry. There’s cell phone service. There’s Wi-Fi. There’s every modern amenity you can think of. The only way we monitor the Quiet Zone is when a new cell phone tower or some sort of technology that’s being put up that’s really ‘loud’ or really powerful, we have engineers that work with them to make sure that it points away from our telescopes.

“There are still some local misunderstandings about what causes us to be so quiet or so cut-off,” said Mulasky. “It’s a mix of both, ‘We have this scientific facility that uses the National Radio Quiet Zone,’ and also that [Green Bank is] a very small, remote, rural, Appalachian town; we don’t have a lot of access to resources. We don’t have a lot of business or industry that would’ve come into the area to give us more.”

Mulasky says that most things on the ground don’t affect the observatory. Instead, it’s objects in the sky, like radio communications from satellites and airplanes, currently delivering the most impact upon the Green Bank Observatory. Thus, with help from the National Science Foundation, the observatory created the National Radio Dynamic Zone around two years ago to work with engineers of such skyborne communications to mitigate any complications that could come up between the telescopes and the overhead radio wavelengths, mainly by having the satellites and aircraft passing over briefly turn off their radios.

Mulasky adds that living in a world where everything is transmitting radio signals all of the time means innovating wherever possible, including software. The observatory’s software engineers are working on filters and programs that can see the interference caused by things like smartphones and smartwatches to filter it out.

“Radio astronomy not only involves what you think of as traditional scientists or even traditional technicians to do the physical work,” said Mulasky. “There’s also tons of software and programming that goes into it. For the past few years, our software teams have been trying to think of different sorts of ‘filters,’ or software programs they can use that can see the interference that’s caused by anything we’re talking about, and just filter it out. We don’t have that technology yet, but we know that it’s important. We’re working on it now, and I would say in 20 years, we’ll surely have that by then. A problem like [filtering radio interference] can’t take 20 years to solve.”

Perhaps by then, the NRQZ will be a quieter place with EVs traversing the roadways, the sound of wind and, now and again, the clatter of diesel engines breaking the silence.

Ask Merriam-Webster to explain the word “truck” and you’ll find this: “a wheeled vehicle for moving heavy articles, such as a strong horse-drawn or automotive vehicle (such as a pickup) for hauling.” Trucks are, by definition, made for work. However, that doesn’t mean they can’t be luxurious inside or improve their fuel efficiency, or even go with an all-electric powertrain.

Truck builder Ram is checking all those boxes with its newest iteration of its Ram 1500 pickup as a 2025 model. The 2025 Ram 1500 is offered in a choice of seven different trim levels: starting with the basic Tradesman featuring the brand’s tried-and-true V6 Pentastar engine to the top-of-the-line Tungsten with a new inline-six engine bolstered by two turbochargers, a 23-speaker Klipsch audio system, and more. Across the lineup, the new Ram 1500 includes an updated electrical architecture that communicates and responds faster, improving everything from the infotainment setup to the safety system. 

And plug-in hybrid and all-electric versions of this truck are just around the corner.

Replacing the legacy V8

This generation of the Ram 1500 launched in 2019 with a brand new body style, and the brand kept the exterior mostly the same for 2025. It has a new grille and the word “Ram” is higher up on the grille, giving it a slightly taller impression. The real difference is under the hood, though. Ram dropped its traditional V8 powerplant, which is a big deal for this brand. Ford and Chevrolet still offer a V8 in their half-ton pickups, while Toyota ditched its V8 for a turbocharged V6 in 2022.

In place of the stalwart eight-cylinder engine, Ram launched its much-anticipated Hurricane. The Hurricane is an inline-six with two turbochargers in two flavors, standard and high-output, with a difference of 120 horsepower (420 hp versus 540 hp) and 52 pound-feet of torque (469 lb-ft versus 521 lb-ft) between them.

Ram isn’t rushing to replace its internal combustion options with all-electric trucks. The automaker’s emission goals are tied to its parent company Stellantis, which is aiming to cut its carbon footprint by 50 percent by 2030, reaching net zero by 2038. Meanwhile, Ram is focused on making its available powertrains as efficient as possible.

Doug Killian, the chief engineer for the Ram 1500, says that even as Ram was launching this generation for 2019, the team was already planning out and thinking about what the next evolution of the vehicle would look like. The straight-six has been in the works for several years.

“We had the straight-six turbo in development and worked on making it more refined, giving it more power, better emissions, and better fuel economy,” Killian explains. “We don’t just launch a truck and then stop; we’re constantly thinking about what’s next.”

Two engines, three flavors

The naturally aspirated V6 is part of a mild hybrid system Ram calls eTorque, which was previously present on the V8. In contrast, the Hurricane is not a hybrid but uses turbochargers; two sets of three cylinders are each fed by a turbo. With the inline layout, each turbo can be a little smaller with less rotational inertia, Killian says. As a result, the turbos spool up faster with less rotational inertia, reducing turbo lag to the point it’s nearly unnoticeable.

“We planned these powertrains and propulsion systems with an inline arrangement, which makes room for the twin turbos on the side of the engine,” Killian says. “The inline-six arrangement gives us more packaging opportunities than the V arrangement would.” 

In competing trucks, like the Toyota Tundra and Ford F-150, the torque numbers are higher than the horsepower; not so for the Ram 1500. 

“In this case, the turbos develop torque at a little higher rpm,” explains Killian. “And we’ve designed the engine so that the bore-to-stroke ratio uses a longer stroke, which gives more power.”

Why keep the Pentastar now that the Hurricane is finally here? Killian says the V6 has a lower power output than the Hurricanes and it will have slightly better fuel economy. The Pentastar offers a lower-cost option with a lower power level, while the twin-turbo Hurricane represents what Killian calls an “extremely advanced” engine. It’s akin to selecting a Dodge Charger; the value option is the basic four-door Charger with adequate power or choosing the one with a screaming 700-hp-plus Hellcat under the hood. 

“Even though the displacement is lower on the Hurricane engine, it has these twin turbos which add a lot more power,” Killian says. “That intake effectively increases the displacement when you need the power.” 

On- and off-road testing confirms Ram’s claims. The new Ram 1500 feels even more capable than before, and the smooth torque of the high-output Hurricane provides a thrilling burst of power on the dirt. Ram did away with its high-performance 1500 TRX and will be replacing it with the new off-road-oriented RHO later this year. We can’t wait to try it.

Too many screens? Why car safety experts want to bring back buttons https://www.popsci.com/technology/too-many-screens-in-cars/ Tue, 05 Mar 2024 19:43:16 +0000 https://www.popsci.com/?p=605505

Automakers must find a balance of high-tech screens and old school controls.

Over the past two decades, iPad-like touch screens in cars have evolved from a niche luxury to a pervasive industry standard. These often sleek, minimalist, in-car control panels offer drivers a plethora of features and customization. However, previous studies suggest these every-day conveniences may come at cost: more distracted drivers. Though regulators have spoken critically of in-car screens in the past, a prominent European safety monitor is going a step further and requiring physical buttons and knobs for certain commonly used driving features if car makers want to receive a top safety score.

Starting in 2026, according to The Sunday Times, the European New Car Assessment Program (NCAP) will only award its top safety rating to new vehicles that use old-fashioned buttons and levers to activate indicators, hazard lights, and other critical driving features. The new requirements could force automakers who use the safety rating as a selling point to reassess the amount of driving features they make accessible only through touch screens. Though these voluntary standards are limited to Europe, a battle over buttons is gaining momentum among drivers in the US as well

Euro NCAP Director of Strategic Development Matthew Avery described the influx of potentially distracting in-car screens an “industry-wide problem” during  an interview with The Sunday Times.

“New Euro NCAP tests due in 2026 will encourage manufacturers to use separate, physical controls for basic functions in an intuitive manner, limiting eyes-off-road time and therefore promoting safer driving,” he said.

What happened to all of the buttons and knobs?

Touch screens are ubiquitous in new cars. A recent S&P Global Mobility survey of  global car owners cited by Bloomberg estimates nearly all (97%) of new cars released after 2023 have at least one touch screen nestled in the cabin. Nearly 25% of US cars and trucks currently on the road reportedly have a screen at least 11 inches long according to that same survey. These “infotainment systems,” once largely reserved for leisure activity like switching between Spotify songs or making phone calls, are increasingly being used for a variety of tasks essential to driving, like flashing lights or signaling for a turn. Consumer Reports, which regularly asks drivers about their driving experience,  claims only around half of drivers it surveyed in 2022 reported being “very satisfied” with the infotainment system in their vehicles. 

[ Related: The 2024 Lincoln Nautilus has a 48-inch panoramic ‘infotainment’ screen ]

“Common tasks that drivers used to accomplish with the simple press of a button or turn of a knob now require navigating through multiple screens, which means more steps, more time, and more attention,” Consumer Reports Auto Test Center Manager for Vehicle Technology Kelly Funkhouser said in a recent blog post.  

There’s various reasons contributing to carmakers’ embrace of touch screens. For starters, the digitized design frees up space in the cabin that would otherwise be cluttered by an assortment of buttons. The tablet-like interface many new models use means drivers can access more intricate features than before, some of which carmakers could use as selling points to distinguish themselves from competitors. Maybe more importantly, the seemingly higher-tech touch screens actually reportedly cost less for carmakers to manufacture at scale than analogue alternatives. 

Digitizing more elements of the vehicle experience also means some carmakers can fix bugs or ship new features through over-the-air, internet updates, which can save drivers a visit to a repair shop. Looking to the future, marketers have also expressed interest in using in-car screens to serve revenue-generating advertising, especially as driver-assistances and autonomous driving features mature. 

Safety concerns tied in-car touch screens 

Touch screen critics warn increasingly complex infotainment systems pose potential safety concerns. A 2017 report from the AAA Foundation claims drivers using infotainment systems to complete tasks like typing in navigation destinations or sending a text were visually and mentally distracted for around 40 seconds. That’s potentially a cause for concern, particularly in light of previous research from Virginia Tech which estimates drivers who look away from the road for more than two consecutive seconds are more than two times as likely to  get into a near-crash. The National Highway Traffic Safety Administration said distracted driving, which can include looking at screens, accounted for 8% of all US traffic fatalities in 2021

NCAP’s new European safety requirements announced this week attempt to address these issues by making physical controls a requirement for any vehicle vying to obtain its highest five star safety rating. The guidelines, which take effect in 2026, will require physical controls for indicators, windshield wipers, hazard lights, the horn, or for activating an emergency SOS feature. These requirements aren’t legally required since the NCAP isn’t a government body but they can still serve as a motivator for prominent automakers like BMW and Volvo who use the NCAP safety rating to tout their safety priorities to potential buyers. 

“We’re working with manufacturers to encourage the safest cars to Bring Back Buttons,” Avery of the NCAP wrote on LinkedIn this week. “Distraction crashes are in the increase [sic] and big touch screens encouraged [sic] distracted driving.”

‘Screen fatigue’ leaves carmakers at a crossroad 

The NCAP requirements come at an inflection point for carmakers, with some investing in larger, more complex screens and others appearing to take a step back. On the screen-maximalist side, Ford and Mercedes-Benz have shipped vehicles with immense “hyperscreen” digital displays stretching 48’ and 56’ respectively. Mercedes and Tesla have both been forced to end over the air updates following rare cases where drivers were reportedly able to watch TV and even play video games on the screens while the vehicles were in motion. 

At the same time, other carmakers like Hyundai and Nissan have responded to possible “screen fatigue” among some consumers by reiterating their commitment to analogue style buttons and knobs. Hyundai Head of Design Sang Yup Lee, for example, recently said the company chose to focus on physical controls to adjust air conditioning and the radio in recent modes. Nissan has recently opted for a mix of smaller screens, physical controls, and haptic feedback. 

Those could be welcome decisions for a significant portion of consumers who are unsatisfied with the drift towards more and more screens. J.D. Power, which recently surveyed drivers about their infotainment systems called the increasingly complex touch screen systems deployed by some carmakers a “prime example of a technology not resonating with today’s buyers.”

It turns out that last month’s report on Apple kicking its tortured, multibillion dollar electric vehicle project down the road another few years was a bit conservative. During an internal meeting on Tuesday, company representatives informed employees that all EV plans are officially scrapped. After at least a decade of rumors, research, and arguably unrealistic goals, it would seem that CarPlay is about as much as you’re gonna get from Apple while on the roads. RIP, “iCar.”

The major strategic decision, first reported by Bloomberg, also appears to reaffirm Apple’s continuing shift towards artificial intelligence. Close to 2,000 Special Projects Group employees worked on car initiatives, many of whom will now be folded into various generative AI divisions. The hundreds of vehicle designers and hardware engineers formerly focused on the Apple car can apply to other positions, although yesterday’s report makes clear that layoffs are imminent.

[Related: Don’t worry, that Tesla driver only wore the Apple Vision Pro for ’30-40 seconds’]

Previously referred to as Project Titan or T172, Apple’s intentions to break into the automotive market date as far back as at least 2014. It was clear from the start that Apple executives such as CEO Tim Cook wanted an industry-changing product akin to the iPod or iPhone—an electric vehicle with fully autonomous driving capabilities, voice-guided navigation software, no steering wheel or even pedals, and a “limousine-like interior.”

As time progressed, however, it became clear—both internally and vicariously through competitors like Tesla—that such goals were lofty, to say the least. Throughout multiple leadership shakeups, reorganizations, and reality checks, an Apple car began to sound much more like existing EVs already on the road. Basic driver components returned to the design, and AI navigation plans downgraded from fully autonomous to current technology such as acceleration assist, brake controls, and adaptive steering. Even then, recent rumors pointed towards the finalized car still costing as much as $100,000, which reportedly concerned company leaders for the hyper-luxury price point.

This isn’t the first time Apple pulled the plug on a major project—in 2014, for example, saw the abandonment of a 4K Apple smart TV. But the company has rarely, if ever, spent as much time and money on a product that never even officially debuted, much less made it to market.

Fare thee well, Apple Car. You sounded pretty cool, but it’s clear Tim Cook believes its future profits reside in $3,500 “spatial computing” headsets and attempting to integrate generative AI into everything. For now, the closest anyone will get to an iCar is wearing Apple Vision Pro while seated in a Tesla… something literally no one recommends.

Built on GM's Ultium architecture, Honda developed the SUV faster than it could have alone.

Honda started developing its Prologue EV in 2020, which became an even more challenging project during the spread of COVID-19. The Japanese brand had agreed on a partnership with the American legacy automakers at General Motors, and face-to-face meetings were off the table. For the entire first year, the two companies met virtually, using video, virtual reality, and computer graphics to develop the vehicle together while halfway around the world from each other.

The fruit of this collaboration led to the Honda Prologue, the automaker’s first all-electric SUV, which arrives in dealerships next month. It’s built on GM’s Ultium battery-electric platform, also used for the GMC Hummer EV (pickup and SUV), Cadillac Lyriq, Chevrolet Blazer EV, Chevrolet Silverado EV, and BrightDrop Zevo 600 (GM’s electric delivery van).

In January, Honda announced its all-EV “0 Series,” launching in 2026. The brand showcased two concept models, Saloon and Space-Hub, at CES 2024. In 2026, Honda will introduce a model of the Honda 0 Series based on the Saloon concept in North America. In the meantime, Honda recognized that teaming up with GM and its battery base could ramp up the progress on its first EV, getting it to market that much faster.

“We delivered exactly what we wanted: speedy development, a proven platform, and that way we got something we could quickly execute,” says the Honda Prologue chief engineer John Hwang.

Blending two different company cultures

GM provided the frame, suspension, chassis, powertrain, and electrical architecture, coupled with 10 battery modules. Honda’s responsibility was what the industry calls “top hat” development–everything you see above the chassis both outside and inside. The Prologue was designed in Honda’s California studio and required the integration of GM components that attach to their floor.

[Related: All the upcoming non-Tesla EVs we’re excited about]

While testing the Prologue in Northern California, it was clear that its one-pedal driving was well-planned. The new EV features three levels of one-pedal drive modes, allowing the user to avoid moving their foot from the accelerator to the brake. Lifting up from the accelerator pedal slows the car down quickly depending on the level, and it has a nice coasting feel when the one-pedal is off. That’s ideal for highways, while a heavier one-pedal setting is better for stop-and-go traffic. This feature is carried over directly from GM, Hwang says.

“We didn’t change a thing,” Hwang told PopSci. “When we were benchmarking and setting targets, we liked how GM was executing this feature, so we said, ‘Don’t touch it. It’s not broken.'”

The Prologue’s Sport button, located somewhat inconveniently to the left of the steering wheel, may be a GM button but the outcome is programmed by Honda. Interestingly, the car uses a passive damping system and there is actually no physical transformation that makes the car feel more grounded and quicker when Sport mode is activated.

“When you press the sport button, it changes the power steering to feel sportier and heavier,” Hwang says. “The throttle mapping is also different, and the EV sound–the whoosh sound–changes. But the sound and the tip in the throttle feeling alters how you perceive the acceleration or motion. Basically, it changes how you perceive it but there is no mechanical change.”

It’s similar to using a touchscreen, Hwang explains; a sound makes you feel like you actually pushed something, but it’s really just the sound coming from the center speaker.

Plugging in the buttons and switches

Honda couldn’t just plug in its own buttons and switches because each must communicate electronically with the platform itself. Engineers from the Japanese company expressed to GM which kinds of buttons it wanted, and based on those requests, GM looked at its catalog and offered Honda options that would work. For example, GM uses toggle switches on the back of its steering wheels to control the audio system, which is not a typical Honda feature. It makes sense in the Prologue as the two put the pieces together.

Keeping some physical switches was important to Honda. The automaker says it is difficult to instantly determine whether a touch panel has been properly operated, unlike physical switches, presenting a potential risk while driving.

Hwang has been with the company for nearly three decades. While he understood the challenges that would come with working on another automaker’s platform, he relished the opportunity to learn. Engineers from Japan eventually met with counterparts in Ohio and Los Angeles in the U.S., creating a global experience.

“It was cool to collaborate in that way,” Hwang told PopSci. “It’s really interesting, because GM uses different terminology and acronyms to describe parts and the process. We would use their English when talking to them and they’d use ours when talking to us.”

Even the symbols were different: Honda uses Xs and circles on its charts, while GM uses checkmarks.

“For me personally, I enjoyed the chance to do something different and new,” Hwang told PopSci. “You get to see how another company works, so that’s always interesting and you learn from that. Every company does things very differently and you discover different perspectives. The ingredients might be the same, but the recipe or cooking method might be different.”

The Prologue boasts a range of 296 miles when fully charged and starts at $48,795.

It’s exceedingly rare to find an SUV that is equally at home on the track as it is climbing rocky hills and splashing through water crossings. Several automakers make capable SUVs that can tackle rough roads and are adequately equipped for passing and merging on a highway, like the Kia Telluride, Ford Bronco, Jeep Grand Cherokee, and Lexus GX. But none of those can also feel like a supercar on the track.

Land Rover has achieved that with its 2024 Range Rover Sport SV, a 626-horsepower beast. We tested the new SUV off-road, tackling steep inclines and stairsteps on its Michelin Pilot Sport All Season 4 tires wrapped around 23-inch carbon fiber wheels. Minutes later, we were pushing it to speeds up to 140 mph on a track atop Michelin Pilot Sport S5 summer shoes. To our surprise, the Rover felt as agile as a supercar.

The enhancements in the freshest Range Rover iteration include a new “6D” suspension, carbon fiber wheels, new custom eight-piston Brembo brakes, and other enhancements that help this SUV press past its previous limits both on- and off-road.

Enhanced “6D” suspension smooths out the ride

Land Rover established itself as an off-road specialist when its first vehicle was unveiled at the Amsterdam Motor Show in 1948. By 1980, it launched its first Range Rover, which elevated the brand as a symbol of luxury and a favorite of the British royal family. In fact, before his death in 2021, Prince Philip designed a custom Land Rover to carry his hearse in the official funeral procession.

The automaker explored its speedier side in the 2022 Range Rover Sport SVR, powering it with a 575-horsepower 5.0-liter supercharged V8 engine under its expansive hood. Now for 2024, the Range Rover Sport SV (dropping the “R”) has a 4.4-liter twin-turbo V8 mild hybrid engine and 51 more hp for a better balance of competence on the asphalt or the dirt. The closest competitor to an SUV this size is the all-wheel-drive Dodge Durango SRT Hellcat, equipped with a supercharged 710-hp 6.4-liter V8 engine that can achieve a 0-to-60 mph time of 3.5 seconds. Its top speed is 180 mph and it tows up to 8,700 pounds quite capably. But it’s not as comfortable going off road, and owners seem to buy it for straight speed and power, not venturing beyond city streets and highways. 

With the 2024 Range Rover Sport SV, Land Rover explored the question: How do you take an extremely off-road capable vehicle and make it perform like a race car? A big piece of that is the software-run crosslink hydraulic suspension system, which keeps side-to-side body roll and forward-and-back pitch under control. It’s a system typically found only in race cars or supercars, the brand says.

“We developed a way to laterally link the crosslink so we can operate axles separately from each other, which gives you more pitch control,” vehicle program leader Jamal Hameedi explained to PopSci. “In some vehicles, when you go to full throttle the hood really lifts up and when braking, the car’s nose dives. This system is pushing the vehicle beyond the [typical] range, staying flat during acceleration and braking.”  

Less mass, more agility

Vehicle Engineering Director Matt Becker had 20-plus years of experience with luxury brand Aston Martin and led the engineering development of its DBX SUV before joining Land Rover. That input gave him a fine-tuned sense of what feels suitably comfortable and performs properly and he can describe that in minute detail. The engineer says that during the development process, one of his software engineers would sit next to him and make adjustments in the code as Becker explained how it should feel.

He was also responsible for reducing unsprung mass to improve agility, which includes using carbon fiber wheels and a lighter brake system. When it comes to handling, it’s not just the mass itself but where it sits that matters, especially as it relates to unsprung mass. In a vehicle, sprung mass refers to everything supported by the suspension system like the body, engine, transmission, computer, cabin, and seats; it even comprises passengers, and cargo. Unsprung mass includes things like the wheels and tires, springs, shocks, and brakes. That’s where Range Rover zoomed in.   

“We wanted to minimize the mass as much as possible,” Becker says. “This vehicle dropped 76 kilos in total, offering more immediacy and connection as well as a better ride quality and stiffness.”

High-tech seats that pulse energy

This Range Rover is furnished with a feature called Body and Soul Seats, or BASS for short. The seats are built as “tactile audio systems” with a set of transducers that transpose energy from one form into another, emerging as pulses in time with the music. Beyond simple subwoofers that throb inside the cabin with raw vibrations, this setup is intended to reduce driver fatigue by stimulating the human body.

Adjustable from levels 1 through 5, the BASS isn’t dependent on volume but preference. Level 1 emits a light pulse that’s almost imperceptible especially when playing easygoing music like smooth jazz or adult contemporary.  Level 5 may rattle your teeth. And it seems choosing a level is a highly personal endeavor, as people have disparate tolerances for vibration as well as the kind of music that resonates most.

Land Rover says this setup improves front-seat occupants’ mental and physiological well being by influencing heart rate variability (HRV), which is the variation in time between each heartbeat. High HRV is indicative of lower stress levels and relaxation. It’s a nice side benefit to the immersive musical experience, too. The back seats are quite comfortable as well, even without the transducers. They recline, making for a lovely undisturbed one-hour nap even on dirt roads.

Every single example of this vehicle is sold out for 2024. However, when asked if this would be the only year of the model, a brand representative said no. With an upcoming all-electric Range Rover in the works, we’ll be watching for more innovations going forward.

Unlike more controversial fully-autonomous self-driving cars, GM’s Super Cruise systems require drivers to keep their eyes on the road and take over control during emergencies.

Adventurous backpackers and small town residents could soon spend part of their car commute without their hands clutching a steering wheel. By 2025, US carmaker General Motors says it intends to expand its Super Cruise Driver Assistance network to include 750,000 miles of roads in the US and Canada. The latest expansion, which places an emphasis on connecting rural towns and cities, means GM drivers can drive on roads with their hands by their side if they are in a GM vehicle equipped with Advanced Driver Assist System (ADAS) features. Hands free or not, the drivers will still have to keep their eye on the road.  

The auto industry’s continued investment in advanced driver assistance systems (ADAS) such as hands free deriving highlights the continued consumer interest in partial autonomous features even as more eye-catching fully autonomous driving systems face renewed consumer backlash

What is Super Cruise and how is it changing?

Super Cruise launched in 2017 as the first commercially available hands-free driving system. Compatible GM vehicles use a combination of on-board cameras and radar sensors as well as GPS data and lidar mapping information to scan roads to help the vehicles stay in their lanes and adjust speed. Infrared cameras in the vehicles are simultaneously used to monitor drivers and ensure they are keeping their eye on the roads. In cases of emergencies, the car will require a driver to regain control of the vehicle. GM refers to this as a “hands-off, eyes-on” system. 

The actual scanning of the thousands of miles of roads is performed by a company called Dynamic Map Platform which uses vehicles equipped with lidar laser sensors to scan the roads. Those scanned maps, which are sent back into a system maintained by GM, show lane level data and topography which helps inform vehicles on when to adjust speeds. The company claims its system can help vehicles stay in their lanes even on rural roadways where lane lines may have faded or are difficult to see clearly with the human eye.

Prior to this expansion, the Super Cruise network had mapped around 400,000 miles of roads in the US and Canada. Support for ADAS systems, both by GM and its competitors, has ramped up in recent years but has primarily focused on urban and suburban areas. Rural areas can often feature narrow lanes lined with tree branches or other environmental debris that can make mapping roads more challenging. Backwoods roads can also have missing signage or other markers which can similarly make mapping roads more time consuming. These factors and others have slowed ADAS and autonomous rollout in rural areas even though residents in those areas may be some of the be suited to benefit from the tech given their lack of access to mass transit. 

GM says it’s planning to add around 40,000 news miles of operational roads to its network every quarter over the next two years. These additions will occur via over the air softwares updates with no additional charge to GM drivers. Dave Craig, GM’s technical mapping specialist, told Axios the expanded areas place an emphasis on getting drivers to “adventurous places and smaller towns.” Super Cruise’s last major expansion occurred in 2022, when it doubled its operational area from 200,000 to 400,000 miles.

“Adding minor highways to the network gives Super Cruise customers more variety and better coverage of hands-free driving, regardless of where they live, work or vacation,” GM said in a press release Thursday.

Driver assistance isn’t the same as full self driving 

Contrary to how the name may sound, advanced driver-assistance systems (ADAS) which includes hands free driving, aren’t the same as more commonly known terms like “autonomous vehicles” or “driverless cars.” Vehicles are measured on six levels of autonomy with zero representing cars with no autonomous features whatsoever and five marking futuristic self-driving vehicles of the future with no need for steering wheels or braking pedals. Super Cruise and Tesla’s well known “Autopilot” systems are considered Level 2. In GM’s case, vehicles using Super Cruise still reportedly can’t handle traffic stops or four way stops. All currently available ADAS vehicles also still require drivers to keep their eyes on the road, which means no highway movies or video zoom calls. 

That admittedly cumbersome autonomy scale isn’t always followed to the tee by carmakers. Tesla, in particular, has drawn regulator and lawmaker scorn in recent years over its use of the terms “Autopilot” and “Full-Self-Driving” (FSD) to describe its ADAS tools that don’t meet the qualifications of fully autonomous. That confusion, critics argue, can lull drivers into a false sense of security in the system which can potentially lead to crashes resulting in serious injury or death. GM specifically contrasts its self-described safety first approach to driver assist rollout to Tesla, which currently lets users trial use its FSD on public roads despite it technically still being in “beta.” 

“Our customers have driven Super Cruise completely hands-free 160 million miles and there has not been one accident attributed to Super Cruise.” Super Cruise  Product Manager Jeff Millers said in a recent interview with The Verge.

“We’re not going to beta test on our customers like some other competitors do,” he added. 

ADAS tools are still more compelling than fully autonomous vehicles, for now

GM’s decision to continue investing in ADAS coverage may allow it to bring more advanced driving technology to consumers without the backlash associated with more fully autonomous vehicles. Last year GM backed Cruise, which offered Level 4 autonomous taxi rides in San Francisco was forced to halt operations in the state indefinitely following a string of safety concerns, including one incident where one of the autonomous vehicles reportedly ran over a woman and dragged her after a hit and run driver collided with the pedestrian. Incidents like those have begun to sour the public’s perception of totally driverless vehicles. Nearly half (44%) of US adults surveyed by Pew said they thought widespread driverless cars would be bad for society. 

ADAS tools and services, by contrast, have attracted more interest among consumers who value them for convenience and perceived safety. In some cases, compelling ADAS features can pull drivers towards certain brands and models. A recent survey of drivers across 15 markets by McKinsey & Company found that 47% of internal combustion engine drivers said they would consider switching car brands for better ADAS features. 74% of electric vehicle drivers said they would similarly switch brands over ADAS. That consumer demand is pushing GM and its competitors to both offer new services and expand the areas where these services can safely operate.  

“Alongside separate work on fully autonomous vehicles with Cruise, safely deploying and expanding access to advanced driver assistance systems, like Super Cruise, is an important step in gaining consumer trust and excitement around the future of transportation,” a GM spokesperson told PopSci. “Super Cruise customers have driven more than 160 million miles accident-free –and we hope that trend continues.” 

In other words, legacy carmakers like GM aren’t giving up on their full self-driving dreams just yet. In the meantime, less publicly-decisive ADAS systems offer a technological bridge to introduce drivers to an increasing array of more autonomous systems.

Since introducing Tesla’s futuristic, angular designed Cybertruck back in 2019, CEO Elon Musk has at times described the 6,603 pound stainless steel behemoth as “badass” “literally bulletproof” and possibly “the best product ever.” But growing complaints from actual Cybertruck owners online say the rugged, all-electric, end-times enduring vehicle may have an unexpected problem: water. 

Cybertruck owners writing in online forums since the truck’s official launch in December have reported noticing small orange dots popping up on the surface of their trucks which they say appear to resemble rust. These customers cited a Cybertruck user manual which advises owners to meticulously maintain the vehicles in order to avoid corrosion and other surface damage. That expectation of scrupulous care seems to contradict Tesla’s own marketing characterizing the Cybertruck as a tough, off-roading hulk meant to rival heavy-story truck models offered by veteran carmakers like Ford and Toyota. 

Cybertruck owners are reporting odd, orange splotches that look like rust 

Heated discussion over the alleged rusting broke out in an online forum called the Cybertruck Owners Club. One commenter going by the name Raxar claims he drove his vehicle through heavy rain in Dublin, Ireland after picking it up and quickly noticed several small orange specks and water spots on the exterior of the vehicle. Raxar says a Tesla representative told him the Cybertruck can “develop orange rust marks” following exposure to rain. The commenter posted several photos purporting to show the odd orange splotches

Another driver writing on the forum claims he also noticed similar orange specs appearing on the exterior of his car after driving it through heavy Los Angeles rain. When he took it into a Tesla facility for inspection he claims he was told a representative “documented the corrosion” and told him they would call next month to perform a service. The Cybertruck owner, who went by the username vertigo3pc, claims the Tesla worker told him they have a “procedure” for addressing the issue but said they did not have the tools on hand to make the necessary repair. He claims he noticed the orange spots after driving his truck just 381 miles. 

Can stainless steel rust? 

Tesla did not immediately respond to PopSci’s requests for comment asking if the Cybertruck’s stainless steel exterior is susceptible to rust. But can stainless steel even rust in the first place? The short answer, according to metal metal supplier Mead Metals, is yes, however it’s less prone to corrosion than other alternative metals. Chromium, one of the elements found in stainless steel, is responsible for its notably higher rust and corrosion resistance. 

“Despite being known for its extremely corrosion-resistant features, stainless steel is prone to rust in certain circumstances,” Mead Metals writes in a blog post. “Although rusty metals are often a result of water exposure, stainless steel will also rust from exposure to damaging chemicals, saline, grease, or prolonged exposure to heat.”

Some Tesla owners commenting in the online forum pushed back against the rust claims and instead said the orange spots may have been caused by carbon dust or other debris from the road. Others, meanwhile, posted screenshots of vehiclce’s owners manual which advises owners to immediately remove any potentially corrosive materials sticking to the car’s body, which could include grease, oil, bird droppings, or dead insects.

 “To prevent damage to the exterior, immediately remove corrosive substances (such as grease, oil, bird droppings, tree resin, dead insects, tar spots, road salt, industrial fallout, etc.),” the manual reportedly reads. “Do not wait until Cybertruck is due for a complete wash.”

That Cybertruck owner’s manual, which isn’t available to the general public yet, appears to note that the base Cybertruck does not have a “clear coat” which means that scratches or other abnormalities that appear only on the surface of the vehicle are in fact in the steel panels themselves. The manual advises Cybertruck owners to use denatured alcohol to remove any tar spots or grease stains from the vehicle’s exterior and then “immediately” wash the affected area with water and a miled, non-detergent soap. Cybertruck owners can opt to purchase an option, clear paint film to their vehicle for an additional $5,000 according to the company’s website. A black or white film is also available for $6,000

Cybertruck owners commenting on the forum offered their own solutions. One owner claimed cleaning the affected areas with Bar Keepers Friend and Windex appeared to solve the issue. It should be noted though that the Tesla owner’s manual appears to advise owners against trying certain DIY efforts. The company, according to the manual, notes it won’t be held liable for damages sustained to the vehicle if user’s failed to abide by those guides. Another Cybertruck owner commenting on the forum offered a blunter solution: just don’t get the truck wet.

“I think as long as you don’t drive it in the rain,” the commenter wrote, “It will be fine…” Others advised owners of the luxury off-road vehicle to “cover that sucker during transport.” 

CEO Elon Musk’s parchment for stainless steel extends beyond Cybertruck or even Tesla. SpaceX, Musk’s aerospace venture, has long-used stainless steel as the main build material for its Starship rocket due to the material’s high melting point and, maybe more importantly, it’s more affordable cost relative to more widely used carbon fiber. Responding to customer concerns over scratches resulting from off-roading, Musk previously said Tesla could offer an option “basically-scratch proof” tungsten carbide coating for an additional fee. It’s unclear if Tesla intends to actually follow through with that idea.

Cybertruck owners report series of odd design choices 

The alleged rust issue, if true, marks one of several growing quality complaints lodged against the Cybertruck which cuts against its tough and rugged premium image presented in marketing materials. Reporting from The Verge last year showed how the Cybertruck’s unconventional design led the company to attach multiple standard windshield wipers together in order to reach across the car’s wide front windshield. Reviewers on YouTube meanwhile have shown how the truck’s sharp angular front trunk can slice through carrots, apples, and hot dogs, when closed too quickly. Other Cybertruck owners have complained the vehicle’s stainless steel exterior annoyingly makes its a fingerprint magnet.

Inconsistencies in quality and unmatched expectations have fueled criticism of Tesla vehicles broadly. In recent years, US regulators have opened investigations into the company after customers reported some models shockingly breaking unexpectedly. More recently, a Reuters investigation claims Tesla appeared to blame drivers for faulty suspensions and other parts failure the company knew were defective. Tesla may have jump-started the industry-wide pivot to electric vehicles, but actual owners don’t seem to be getting exactly what they asked for in every case.

“And don’t forget to breathe.”

These are the last words I hear before the doors shut, and I forget to breathe. I’m choking on air pressure, disoriented by displacement, and all I do remember is that someone said there’s a panic button a few inches to my right—a big red button I desperately want to punch through the wall.

But I force myself to inhale, will myself to exhale, keep my clenched fist tight to my chest, and 45 seconds of suffocating cycles later, the doors reopen. Shaking my head, my thoughts begin to settle, and I start to remember where I am, why I’m here, what I’m hearing. 

I’m in Tempe, Arizona, in the garage at the headquarters of audio solutions designer and distributor Rockford Fosgate. I’ve just staggered out of the mobile SoundLab “Pressure Chamber”—a purpose-built enclosure in the back of a van that produces a low-end onslaught to demonstrate the brute force of four 19-inch T3 super-woofers, eight 6.5-inch Punch Pro midrange woofers, four Punch Pro bullet tweeters, and 11,000 watts of power. This exercise in excursion punctuates a day where I’ve toured every decade and company department to see how speakers and amplifiers are engineered for elevated performance and adrenaline spikes.

A lot goes into output

If you’ve been into car audio, you’ve probably been in a car with some Rockford audio. The company was launched in 1980 by Jim Fosgate, who invented the Punch EQ in 1973 to make music more impactful before introducing the first car amplifiers to form the brand’s foundation. In the mid-1980s came Punch woofers, followed by computers, decoders, source units, signal processors. From four amps to over 40 years goes the story—hundreds and hundreds of components for mobile, marine, and motorsports. All recognizing that you can’t just take a car speaker, paint it white, and install it in a boat if you want it to last and make a lasting impression.

When I was young, I had friends into 12V (standard voltage for car audio systems and an enthusiast nickname), so I was familiar with the brand even if I never got to turn the family Dodge Caravan into an amateur SoundLab. While they were putting up posters of cars they coveted, Rockford was adding to its very real, very extensive patents wall. But that was just a consumer’s experience; I’m here to explore how concepts move forward in-house and on the road. And the first thing I learn is that you can’t separate the end-users and the end product, even when it’s beginning. 

So many people I’m introduced to throughout the day live up to the company’s tagline, “Built By Fanatics, For Fanatics.” If they haven’t worked for the company for 10, 15, 20 years, they at least worked for a Rockford dealer before they did. Almost everyone has a story about a custom job they did or a prototype they field-tested in their car, Side-by-Side, motorcycle, pontoon. Some of their personal low riders and bikes are in the company’s lookbook; their faces affectionately mean-mugging in promotional videos. But even if you can’t see them, the whole Rockford family’s proverbial fingerprints are all over everything. 

The tour begins, as many things do, at the beginning. In this case, that’s with Wayne Connolly, director of new product development, in the NPD corner—home to the company’s five-year roadmap and a repository for original equipment manufacturer (OEM) and aftermarket product ideas. Connolly walks me through how, with the front of the building as a steering committee, a living list tracks commitments to growth in each category—whether that’s custom Harley-Davidson kits, plug-and-play Stage-5 Jeep systems, or the Power, Punch, and Prime factory upgrade lines, to name a few. This list is fed by suggestions for product research and revisions from people who live the lifestyle. Whether talking to dealers at trade shows and fans at the Sturgis Motorcycle Rally or just spending weekends taking out the UTV or spending time on the lake, project managers are in the feedback loop. 

As the market has shifted, there’s more and more of an emphasis on plug-and-play, easing consumer pain points, providing installation kits that give the confidence to tackle them on their own. And it’s up to the team to recognize when a vehicle’s suspension switching introduces a harmonic and how digital processing can compensate, how to make small systems sound larger while keeping them lighter. It’s about identifying how to control the experience, how to reduce variables without diminishing options.

Once the business case is made, project management takes over. Supervisor JD Massad explains how the teams align to start the phase gate development process and ensure that, no matter how regimented things are, there’s a smile on everyone’s face at the start and the finish. The original vision needs to be addressed, but there are always lessons to be learned for other categories once dollars are attached; people are accountable; basic prototyping begins. On this side of the building, it’s a background in hand-built samples, a love of MDF, Bondo, sandpaper. On another, scanners and CAD, fabricators, and 3D printers. Together, it’s a great fit (and refit and refit and refit … depending on the product iterations).

Next door is RTTI, or Rockford Technical Training Institute. It started as a “Top Gun” program, bringing in nationwide installers to teach them how to work tighter, cleaner to give Rockford dealers an advantage. RTTI also handles building demo vehicles (like the SoundLab) to showcase the brand at events. And, on top of all that, RTTI works with the mechanical engineering team to develop enclosures and wiring harnesses and all the other parts to a Goldilocks box that answers the problem statements. Or, as Rick Jones, vehicle applications manager, puts it, laughing, “We chase shiny objects back here.” 

For example, a few years ago, a group of RTTI guys set out to address how to get more low energy on a motorcycle; where to fit a subwoofer on a Harley. A saddlebag was the logical solution, but one of the biggest challenges was not forcing a rider to give up storage space permanently. So, making the enclosure removable became the primary objective, requiring custom parts to manage wires.

Rockford Fosgate

What makes RTTI, and Rockford in general, perfectly suited for this challenge is the wealth of machines (including SawStop, CNC, and router tables, FDM and resin 3D printers and laser cutters) plus the interplay between departments. When it comes to sound for speed, speed to market is key to success. So once they decided on the slim-fit woofer and a sealed versus ported enclosure, the team could quickly pull a mold of the bag, do some fiberglass models, foam them out. Pretty close? Grab the Creaform 3D scanner, capture the rough mock-up and more exact vehicle dimensions, then kick the concept to mechanical engineering to clean it up in CAD to get the exact geometry and ensure the driver’s full excursion clears obstacles—all to make sure it fits the mechanical envelope. Do some thermal modeling. 

Soon, the time comes for a rough 3D print to outfit with an actual driver and make sure everything is hitting the acoustic target. Then it’s on to fit, fastenings, finish … a textured pre-production part. A physical object that lets you know if the render translates into something inspiring to handle. Straightforward, eh? It almost sounds simple (it isn’t) … maybe if the goalposts didn’t change constantly (luckily, project management’s got their back as things move forward).

You’ve gotta be flexible to get the right stiffness

From the install bay, we wander to the engineering bullpens—tight pods of cubicles set up for quick collaboration, a FaroArm scanner set in the center as another tool to get prototypes into SolidWorks CAD and make sure drawings match parts. Detection, inspection, perfection. Here, they help realize the vision of how parts should integrate with vehicles, assuring every bracket allows an easy install and every material choice and position allows for airflow and thermal efficiency, all while working with an industrial design team to marry Rockford’s visual flavor with the mechanical intent.

On the other side of the aisle is loudspeaker engineering, tasked with ensuring everything put in those painstakingly designed enclosures sounds good and holds up no matter the sustained volume or extenuating circumstances. Unlike two-channel home audio manufacturers, who have the luxury of designing for controlled environments, Rockford has to look beyond magnetics, electrical, thermal, acoustic motion to motor structures, spiders, suspensions—all parts that can perform in and stand up to open-air elements.

Rockford Fosgate

Frank Barone, director of acoustic engineering, and Ada Puyot, acoustic design engineer, walk me through modeling software for motor geometry. Simulations allow the team to see the typical things, like efficiency, how low it’s going to play, motor force, how much it can move without getting distorted, etc. Any changes—for example, to the length of the voice coil, the fine wire that reacts to the motor’s magnetic field and moves the speakers—are reflected in real-time, showing how decisions will affect the sound signature. The press of a button can change the shape and surround of a speaker, pull up any legacy assemblies to see what can be adapted. 

And after broad simulations comes far more granular finite element magnetic modeling, which allows for fine-tuning, seeing how any tweaks to material will impact response well before actual money is on the line. Seeing how to avoid saturation can improve design while addressing costs. Being able to change spider geometry or corrugation heights helps design for the roof of a UTV versus a standard car mount. Programs inform what individual parts are worth ordering to test to see where prediction meets actual measurements on the way to a finished product. A wall of code-named concept speakers shows how many precursors go before production. Purpose-built, indeed.

All the modeling in the world doesn’t matter if the math doesn’t check out, of course, and that’s where the testing and validation department comes in. Once it’s decided that it’s worth calling in hard parts for prototyping, it’s handed over to Tom Dubeck, loudspeaker technician, and the Klippel diagnostics system. Measured in a test baffle with a combination of a laser displacement sensor to calculate efficiency and a microphone for acoustic data, material parameters like how much force it takes to move a cone five or 10 millimeters can be analyzed, helping determine what stiffness and damping are needed. Collecting these parameters informs the modeling of how the speakers perform in different boxes and situations.

Getting farfield measurements and capturing curves is invaluable. But people who don’t measure output response don’t listen to sweep tones quickly running through low to high frequencies. So, on the other side of the room are two shrouded arrays of speakers in development. Versions with slight changes—to motor structure, tweeter material, crossovers, what have you—are set in parallel behind acoustically transparent fabric, flanked by in-production Rockford drivers as well as competitor transducers. Folks from around the building come in to do some partitive listening and take notes. 

Speakers photo
Rockford Fosgate

One place they don’t go to listen, however, is our next destination. It’s called the Boom Room, a trailer separate from the main building where Dubeck puts devices under test through a gauntlet, leaving them to play at full volume for days—first to see if they can maintain at a certain voltage and then pushed to the point of failure. A Klippel system in the Boom Room control room monitors a test of up to eight speakers at a time, generating a signal sent to 1600W amplifiers that is sent back to the Klippel and out to the drivers. Subwoofers, ported and sealed, can be seated in permanent enclosures, while full-range speakers hang from the ceiling. It smells of torn surrounds, burnt voice coils, and victory. There’s also an apparatus to simulate high ambient temperature if components need to be evaluated in a thermal chamber. Eventually, the speakers return to the control room, where autopsies are performed and points of failure confirmed.

Eventually, prototypes graduate to production runs, which is when the Klippel system comes into play one last time. Assembly lines are equipped with special QC enclosures, and every speaker that rolls off undergoes a short tolerance test of nonlinear parameters to ensure there’s consistently no distortion and impedance falls where it should.

So, a new speaker is born. But it still needs help finding its voice. And that takes place in the tuning room—a room big enough for a car, UTV, or a couple of Harleys, which is what’s in there when I meet Joe Merritt, acoustic systems engineer, to hear about how the amplifier’s DSP is used to put the finishing touches on the sonic signature. 

In the case of the H-D CVO platform, which is fitted with a model-specific speaker and amp package, Rockford has a custom six-microphone rig built into a seat, so it’s perfectly positioned. The microphones are at various heights to simulate the range of average rider heights and reflect what they’re hearing. The room also allows the engine to run and the bike to be tricked into thinking it’s moving at speed, so the dynamic EQ reacts accordingly. Plus, there’s a PA for playing wind/road noise. The microphones feed their readings to a computer sound card, and a real-time analyzer puts an average curve up against the target—a rising response with naturalistic mids surrounded by energized bass and treble to compensate for outdoor applications. The DSP chip is then tweaked to achieve the desired outcome—one of the benefits of one company producing all the kit components.

Staying power

It’s now time for the last tour stop, which is also the company’s starting point: amplifiers. Rockford started out producing big power, big watts per dollar, Class A/B all the way. But vehicles have gotten smaller and—especially in the case of motorcycles and marine—the company adapted, moving into the more compact, higher efficiency Class D. Similarly, in 1993, the company introduced something called Symmetry, which was a modular, card-based rack computer for the car—DSP before it was convenient. Since then, there have been infotainment systems and other integration pieces. Rockford has always evolved while maintaining an approach that controls the signal path from start to finish for maximum reliability.

Erik Gundersen, director of advanced engineering, walks me through the solder and sine waves. As in all divisions, there’s a real whiteboard-to-blacktop approach, with simulations allowing the team to tweak circuits on a screen well before anything gets to PCB layout and physical samples. And there are a host of internal and external challenges, from designing an amplifier that can maintain more uniform power across varying impedance loads to dealing with radio frequency challenges and electromagnetic compatibility in the age of Bluetooth, WiFi, USB, DSP. Especially with the finite form factor in something like a Harley, where it’s harder to ensure tightly oriented circuitry won’t produce interference and excess energy will have somewhere to dissipate. Marine products have to perform in completely different harsh conditions. Plus, everything needs to play nicely with RF Connect, the proprietary smartphone app that pairs via Bluetooth and allows users to set up, control, tune, and update products. At the same time, electric vehicles open up new possibilities, if current from their batteries is opened up.

One of the ways Rockford guarantees its amplifiers perform (often over-perform) as promised is through another homegrown creation: RATS, or Rockford Automated Test System. Jason Gerlitz, senior production validation manager, explains that all overseas production facilities have this custom hardware-software combo and—as units undergo tests for Signal-to-Noise Ratio, burn-in, and more—results are sent to the cloud so that headquarters can analyze it and identify any issues. And only devices that pass every test get a “birth certificate,” as well as a serial number, allowing them to ship.  

And once they’ve shipped? Well, Rockford even films its own installation videos—providing a visual reference, the estimated time it takes, and the expected difficulty. They have a podcast studio, as well, to produce collateral for dealerships and OEM partners that maintains the brand’s voice. The same marketing team responsible for all this output to promote current products is always gathering input from shows and social media to feed back into the steering committee and product development. Know what they didn’t capture, thankfully? My time in and after the SoundLab. That doesn’t mean I’m done with Rockford’s demo vehicles, however.

To wind down the day, we drive northeast of Tempe out to Saguaro Lake. First, we take a Polaris Ranger onto the Butcher Lake off-highway vehicles trail. The SxS is equipped with a Rockford “Element Ready” all-in-one concept, including an audio roof with eight 8-inch speakers, two 10-inch subwoofers, a 1500-watt amplifier, and a 2.7-inch source unit, as well as a rear audio cap with four more 8-inch speakers and 800 watts and 10-inch subwoofers under the back seat. I’m told that despite all that, the system can be easily installed in under an hour, ready for the trails, dunes, mud, bonfires. The rocky loop we take does a great job of rattling my bones, but even if we were stationary, the $10,000 in closed-loop audio concepts would have left me thunderstruck.

Finally, we head down to the lake itself and board a supercharged pontoon equipped with the company’s Marine Audio components, naturally. It’s a different environment but the same built-to-endure experience. Requests are taken, and while I might not love Steely Dan or Dave Matthews Band, I can appreciate the open-air clarity delivered by these shiny objects. As I reflect on Rockford Fosgate’s commitment to engineering from the ground up, even when the ground is this big blue watery road, I don’t forget to relax and breathe.

Vandals thoroughly obliterated a Waymo autonomous taxi in San Francisco’s Chinatown on Saturday evening to the cheers of onlookers. In an emailed statement provided to PopSci, a Waymo spokesperson confirmed the vehicle was empty when the February 10 incident began just before 9PM, and no injuries were reported. Waymo says they are also “working closely with local safety officials to respond to the situation.”

A San Francisco Fire Department (SFFD) representative also told PopSci responders arrived on the scene at 9:03PM to a “reported electric autonomous vehicle on fire” in the 700 block of Jackson St., which includes a family owned musical instrument store and a pastry shop.

“SFFD responded to this like any other vehicle fire with 1 engine, 1 truck, and for this particular incident the battalion chief was on scene as well,” the representative added in their email.

Multiple social media posts over the weekend depict roughly a dozen people smashing the Waymo Jaguar I-Pace’s windows, covering it in spray paint, and eventually tossing a firework inside that set it ablaze—all to the enthusiastic encouragement of bystanders. After posting their own video recordings to X, one onlooker told Reuters that someone wearing a white hoodie “jumped on the hood of the car and literally WWE style K/O’ed the windshield & broke it.” Additional footage uploaded by street reporter “Franky Frisco” to their YouTube channel also shows emergency responders dousing the flaming EV, which reportedly caught fire after someone tossed a firecracker inside the car. Chinatown’s streets were already crowded by visitors attending Lunar New Year celebrations.

Speaking to The Autopian, Frisco says that they have covered similar autonomous vehicle situations in the past, but this weekend’s drama left the Waymo vehicle looking “completely ‘decapitated.’” Upon arrival, emergency responders reportedly even had difficulty discerning whether it was a Waymo or Zoox car. Although both companies (owned by Google and Amazon, respectively) offer driverless taxi services, neither fleet resembles one another—when they are in better condition.

Motive for Saturday night’s incident remains unclear. The event took place as locals continue to push back against autonomous taxi operations in the area. Since receiving a regulatory greenlight for 24/7 services in August 2023, numerous reports detail cars from companies like Waymo, Zoox, and Cruise creating traffic jams, running stop signs, and blocking emergency responders. In October 2023, a Cruise driverless taxi allegedly hit a pedestrian and dragged her 20-feet down the road. Cruise’s CEO stepped down the following month, and the General Motors-owned company subsequently issued first San Francisco, then nationwide, operational moratoriums.

Not only is this weekend’s autonomous taxi butchering aggressive, dangerous, and illegal—it’s also apparently a bit of overkill. According to previous reports, driverless car protestors around San Francisco have found that simply stacking orange traffic cones atop a taxi’s hood renders its camera navigation system useless until the obstruction is removed.

The science behind winter tires https://www.popsci.com/technology/the-science-behind-winter-tires/ Mon, 12 Feb 2024 16:00:00 +0000 https://www.popsci.com/?p=602269

Bridgestone uses microscopic bubbles and tiny slits to help its tires grip ice and snow.

The American Automobile Association (AAA) says winter storms and bad weather that result in snow or ice-covered roads cause nearly 500,000 vehicle crashes and more than 2,000 road deaths every year. Driving too fast, braking too hard, and swerving quickly has the potential to cause a loss of control. Tires play a big part in that equation, and factoring in the wrong tires for inclement weather or driving on tires with too much wear can equal disaster.

Tire companies are constantly working to improve winter tires to enhance driving safety, and tread, materials, shape, and design all play a role in the overall driving experience. We tested a variety of winter tires on slippery, snowy roads on a closed track at Bridgestone’s Winter Driving School in Colorado. In the process, we learned about what works (and doesn’t work) when the rubber hits the snow and ice.

Tread patterns and sipes

When it snows, choosing the right footwear is an important decision. Low-profile slip-on flats or low-tread loafers wouldn’t be a smart choice because they leave too much skin exposed to cold and wet. Plus, the probability of slipping on the ice increases exponentially. Rubber soles with large-pattern tread on winter boots makes more sense. Tires work in similar ways but incorporate specific technology and materials designed to keep thousands of pounds of metal (and its passengers) from skidding off the road.

If you’ve ever slid on the surface of slippery asphalt in your car, you know the alarming feeling of losing that control. During heavy rain, the tires on your car push the water forward, creating a wedge of liquid that can cause the tires to lose contact with the road; that’s called hydroplaning. The risk of hydroplaning increases in deeper water, and riding on tires with tread made to withstand those conditions is critical, as is ensuring the tires are not worn down, decreasing the tread.

The tread pattern is different on winter tires than what is on all-season and summer tires. Summer tires are more suited for curvy cruises on dry roads, with wide tread patterns. Winter tires include deeper treads and more sipes, which are tiny slits in the tire that dig into the snow, acting as biting edges on ice. Sipes gap open as tires roll across the driving surface to push snow or water away from the tires’ contact area, improving the grip. Together with the edges of the sections (called blocks) in the tread, winter tires offer better handling in winter weather.

On top of that, Bridgestone uses a proprietary technology that incorporates microscopic bubbles in the tires that disperses the thin layer of surface water. By moving that out of the way, the sipes and tread can do its work to bite into the ice and snow to keep control.

What may surprise some people is that snow on snow is what creates traction, which is why the depth of the tread is so important. 

“When you make a snowball, it packs together because snow wants to stick to itself,” explains Will Robbins, a 20-year veteran tire specialist from Bridgestone. “The snow-on-snow is what gives you that grip when you brake or accelerate.”

Imagine the act of sticking and then unsticking two corresponding pieces of Velcro together, and then apart. The sticky edges of the snowflakes push together and pull apart with grip, not slip. 

Tire structure 

There are basic similarities between winter and summer tires, Robbins says, starting with the carcass. The carcass (also called the casing) supports the load, and that part stays constant; the tread is what makes the difference. 

Inside a tire, a steel loop made from fine steel wire comprises what’s called the bead. That’s what grips the tire to the wheel. The body ply attaches to the bead, and it’s made from strong fabrics like polyester and rayon. Stiff steel cords make up the belt, which gives the tire structure. And rubber compounds are used for the sidewall and the tread. 

Incorporated into the tread and sidewall are several other materials. Carbon black is a fine black powder, essentially composed of elemental carbon, which increases the strength of the rubber. Sulfur adds greater elasticity. Oil softens the rubber. And silica, the white powder of silicon dioxide, delivers better fuel efficiency, durability, and grip. However, silica is tricky because it soaks up water while rubber repels it; Bridgestone uses a technology that helps the rubber bind to the silica. 

Treads wear out eventually, but Bridgestone and other tire companies are exploring more retreading options to improve the overall sustainability of the process. The future holds promise for increased tire recycling options and increasing the use of renewable materials. Meanwhile, Robbins says, tire casings can be used over and over again by replacing the tread. It’s like replacing the sole on a favorite pair of shoes, allowing the structure of the shoe to remain while it’s resoled, giving the shoe (or the tire) new life. Ensuring the soles of the shoes on your car are maintaining a solid tread isn’t just for looks; tires can protect the lives of those in the car and anyone else in their path.

PSA: Don't. X

Videos of what looks like Tesla drivers using the new Apple Vision Pro “spatial computing” headset while in Autopilot mode are going viral, but at least one is staged. After getting over 24 million views on X, 21-year-old Dante Lentini may still face legal repercussions for his stunt.

In an email to PopSci on Monday, Lentini confirmed a video appearing to show him being stopped by police for using Apple’s $3,499 headset behind the wheel of his Tesla was filmed in a “skit-style fashion.” The 25-second clip shows Lentini sitting in the Tesla driver’s seat while traveling on a highway using Autopilot. Instead of keeping his hands on the steering wheel, as Tesla directs all users to do while in Autopilot, Lentini gestures to imply he is using Vision Pro’s interface. (The Apple headset relies on interpreting specific hand movements to navigate and utilize its apps.) The video then cuts to Lentini in a parking lot as a police vehicle flashes its lights behind him.

“So the police were not even in the parking lot for me to begin with,” Lentini alleges in the email. “I wasn’t pulled over never mind [sic] not being arrested nor ticketed.”

Lentini uploaded his clip to X on February 2, the same day Apple’s Vision Pro headset hit stores, but it wasn’t until this weekend that the post began gaining momentum. Numerous outlets have since covered Lentini’s video, as well as similar content. A different video posted to X on February 3 appears to show another Apple Vision Pro user in the driver’s seat of a Tesla Cybertruck. Like Lentini, the driver makes gestures known to control the headset, implying the $60,990 base price EV is engaged in Autopilot or Full Self-Driving Beta mode. The Cybertruck video has racked up over 17 million views by Monday morning.

In a follow-up email to PopSci, Lentini confirmed he used Tesla’s Autopilot program during his video after he “got over to the right most lane [sic].” He also claimed he only wore Apple’s headset for “10-15 second increments” totalling “less than 30-40 seconds combined.” 

“I believe the Vision Pro doesn’t even work while traveling since the technology fails to be able to track your reference surroundings and place the graphics accordingly,” he continued. “So all it showed was a pass through video feed,” referring to the headset’s ability to visualize external surroundings with a reportedly 12 millisecond latency, “as if I was just wearing sunglasses.”

[Related: Here’s a look at Apple’s first augmented reality headset.]

Most US state traffic laws prohibit wearing anything that could potentially obscure a driver’s ability to see their surroundings. In Palo Alto, where Lentini claims to reside, “it is unlawful for a person to drive a vehicle if a television receiver, a video monitor, or a television or video screen, is operating and is visible to the driver.” Violations could include a fine of $238, as well as a point added to the driver’s DMV record.

A previous review of the parameters within Vision Pro’s visionOS coding indicates it disables certain features if it detects users traveling over a “safe speed,” although it’s unclear if this applies to driving. A separate “Travel Mode” can reportedly be enabled while “stationary” in an airplane, but Apple does not offer an explanation of how Vision Pro assesses the speed, travel, and passenger status. 

According to Apple’s official product page, the Vision Pro includes built-in safety features meant to help prevent collisions and falls. “[I]t’s also important to use the device in a safe manner. For example, don’t run while wearing Apple Vision Pro, use it while operating a moving vehicle, or use it while intoxicated or otherwise impaired,” the company states.

Lentini suspects similar viral content videos are also “skits.” Although he understands “some people’s initial frustration” after seeing his clip, “there’s nothing obstructing my vision. I personally feel like it’s more dangerous to text and drive or even eat and drive, even though I still recommend not wearing these while driving.” Illegal “distracted driving” is defined on a state-by-state basis, but usually includes texting. In some places, eating can also fall within the bounds of distracted driving. 

Whether or not flashy, bank-draining luxury items like Apple Vision Pro and Tesla Cybertruck will prove successful remains to be seen. For now, at least, the combination is leaving bystanders dizzied by the whirlwind mix of legality, wealth, virality, and veracity—all exacerbated by such posts’ ability to spread across platforms like X.

The EV industry faces a core challenge: software bugs https://www.popsci.com/technology/ev-software-bugs/ Mon, 05 Feb 2024 18:19:33 +0000 https://www.popsci.com/?p=601456

Automakers like Ford, GM, and Volvo are rethinking their pace.

Cars running on all-electric battery power include high-tech operational systems that are dramatically different from gas-powered setups. EVs are highly dependent on software–not just the infotainment system or within the touchscreen, but from bumper to bumper. These are “software-defined vehicles,” which is an industry term that illustrates the difference between a car enhanced by technology and one that is run by technology. 

The problem with software, especially in its first iteration, is that it can be buggy; just ask Apple, whose software troubles reportedly caused iPhone 15 models to heat up excessively. As a result, software bugs can cause both evident and phantom issues that are difficult to pinpoint within a mountain of code. 

Although the push for all-electric vehicles is increasing due to both competitive one-upmanship and government encouragement, some manufacturers (including GM, Volkswagen, and Volvo) are taking a beat to evaluate their software development process. GM, for example, delayed production of its electric trucks, including the Chevy Silverado RST and GMC Sierra Denali EVs, at its Ohio plant until late 2025. Volvo postponed deliveries of its new EX30 due to software challenges. As the adage goes: measure twice, cut once.

Growing pains

It’s a common belief among consumers that it’s a bad idea to buy the first model year of a car. In the past, more people believed manufacturers needed a year “to get the bugs out” before the car was ready for mass distribution. However, today’s automakers are more efficient than they’ve ever been, and they’re more likely to build on shared platforms and parts that are tried and true from specialty manufacturers. Software, on the other hand, is a wide-open universe, and code varies from vehicle to vehicle.

EV specialist Tesla has issued a string of over-the-air updates to correct software problems. Some are small, such as the most recent recall regarding the size of the brake warning; others are significantly more impactful, like those affecting the cars’ driving-assist feature. In most cases, the over-the-air updates fix the problem without customers having to bring their vehicle to a physical location

Ford (and its luxury arm Lincoln) has shifted to growing its in-house software development team for the brand’s new infotainment system. In the past, the company relied on suppliers for hardware and software, but Ford technical specialists say bringing the development in-house is faster, cheaper, and results in higher quality.

Smaller automakers may not have the resources and personnel to make such a big investment in technology infrastructure, so their future is hitched to outside providers. Either way, whipping up lines of code is a major shift in the automotive industry, and growing pains seem to be inevitable.

Ed Kim, president and chief analyst of automotive research and consulting firm AutoPacific, points out that legacy automakers are challenged with a daunting task. They must learn very quickly how to create all-encompassing software for automobiles when their expertise has long been the physical nuts, bolts, and components that cars are made of.

“In the emerging software-defined era, software is absolutely integral and critical to all aspects of a vehicle’s operation, but software is out of the realm of expertise for most automakers,” Kim says. “They are currently learning at a frantic pace, recruiting expertise from the tech industries to help them not only understand and integrate software into their vehicles, but also grasp how they can innovate for the consumer’s benefit and take automotive to places it has never been.”

Exterminating the software bugs

Even EV companies born in the battery-electric world aren’t immune to the same software challenges. Rivian, one of the newest manufacturers in America, accidentally torched the infotainment system and main instrument display of some customers’ vehicles in November with a “fat fingers” error during the rollout.

Rivian’s VP of software engineering Wassym Bensaid posted an explanation on Rivian’s subreddit page:

“We made an error with the 2023.42 OTA update – a fat finger where the wrong build with the wrong security certificates was sent out,” Bensaid said. “We cancelled the campaign and we will restart it with the proper software that went through the different campaigns of beta testing. Service will be contacting impacted customers and will go through the resolution options. That may require physical repair in some cases.”

Chevrolet started delivering its much-anticipated 2024 Blazer EV in the middle of last year and then pulled the vehicle with a stop-sale notice in December after a major software problem. Car site Edmunds bought a Blazer EV as a long-term test vehicle, and the SUV threw 23 fault codes within the first two months, confounding the team.

“The consequences of getting software wrong–even if it can be fixed quickly over the air–can be much more dire [than it might be on a smaller appliance],” says Kim. “A software flaw that may be an inconvenience on a malfunctioning smartphone app can be catastrophic and life-threatening in an automobile.”

During a GM fourth-quarter earnings call last week, CEO Mary Barra told investors that GM’s software and services team is working “with a huge sense of urgency” to fix the challenges plaguing its new EV. The good news for GM and other automakers is that while software bugs are inevitable, they’re not beyond extermination. With upcoming launches of the Chevy Equinox EV, Silverado EV RST, GMC Sierra EV Denali, and Cadillac Escalade IQ on the docket, the legacy manufacturing group is adding in some extra time for vetting and testing. It’s a smart strategy for GM and its customers, and will pay off in time.

These simulators popped in the 1950s, but there's a reason you won't see them in accredited driving schools today.

From cities in the sky to robot butlers, futuristic visions fill the history of PopSci. In the Are we there yet? column we check in on progress towards our most ambitious promises. Read more from the series here.

In 1953, dozens of teens at Brooklyn High School for Automotive Trades took one of the first-ever realistic driving simulators out for a spin. The Drivotrainer was no Gran Turismo, but it offered road video and a bumper car-style driver’s seat with a steering wheel, clutch, brake, mirrors, speedometer, and even a hood ornament. 

When Popular Science covered the Drivotrainer’s Brooklyn, NY debut in May 1953, teen driving accident rates in the US were skyrocketing, blamed largely on an increase in automobile access and lack of adequate training. For the 15–24 age group, motor vehicle death rates had surged over the prior decade, more than doubling by 1956 to nearly 43 per 100,000. But it was too costly for schools to provide enough dual-control training cars and instructors to meet the increased driver-education demand. Since flight simulators, which were first introduced as early as 1910, helped prepare pilots for real-world flying, traffic safety experts hoped that driving simulators would yield similar results for young drivers and reverse the troubling car-crash trend.

For the unlikely developer of Drivotrainer, Connecticut-based Aetna Casualty and Surety Company (now owned by CVS), driver education and accident prevention was good not only for its bottom line but also for its reputation. Aetna had been investing in driving-simulation technology as far back as 1935, when it introduced its Reactometer to measure driver response time. The Reactometer was followed by the Steerometer and then the Driverometer, an arcade-style machine that offered motion pictures to simulate driving conditions.

In May 1951, Popular Science featured Aetna’s next generation simulator, the Roadometer, a driving test that employed video and a booth-like car seat. The Drivotrainer, designed for classroom training, improved upon the Roadometer’s design by automating scoring and separating the video from the booth, enabling it to be projected on a large screen for a room full of students seated behind the wheels of Aetnacars. Success, however, could only be measured by how well simulator-trained drivers performed on the road relative to their untrained and road-trained peers. Aetna needed proof of simulation training’s positive impact.

Positive transfer of training is a concept based on developmental psychologist Jean Piaget’s theories of cognitive development, published in numerous works between the 1920s and 1940s. Specifically, the law of assimilation proposes that we tend to respond to new situations in ways that are similar to familiar situations. The idea of a driving simulator is to familiarize students with driving fundamentals and challenging traffic scenarios before they take to the road. 

“We can put people in scenarios that they may never experience and make them aware of the risks and dangers [of driving],” Eric Jackson, Executive Director of the Connecticut Transportation Institute (CTI), a research center at the University of Connecticut, tells PopSci. In addition to compiling car crash data to track trends, Jackson’s team operates a variety of driving simulators to study driver behavior under different conditions such as when a driver is impaired or distracted. CTI’s simulator collection includes a car mounted on actuators with a surround screen, and several motorcycle simulators. They also use desktop and virtual reality simulators. 

According to researchers from Sweden, who used a driving simulator test in 2023 to complement on-road testing, simulators are an effective way to test drivers in unusual hazardous situations, as Jackson suggests. Their simulator tests put drivers in scenarios too risky for road tests and successfully flagged deficient driver reactions. 

The six-week Drivotrainer course at the High School for Automotive Trades—a vocational school that still stands on Bedford Avenue in Brooklyn, NY’s Greenpoint neighborhood—was one of several Aetna-sponsored driving simulator trials conducted around the US in the 1950s. Others included students from William Cullen Bryant High School in Queens, NY; Iowa State Teachers College (now the University of Northern Iowa); and Hollywood High School in Los Angeles, CA. At the time, the American Automobile Association (AAA) had developed its own driving simulator, the Auto Trainer, which was trialed at Anacostia High School in Washington, DC, and in Springfield, PA. 

A 1960 report by the National Commission on Safety Education analyzed the Drivotrainer and Auto Trainer trials and concluded that “some transfer of learning occurs when [driving simulators] are used.” But the report also noted significant gaps in the available performance data and called for additional testing. Looking to the future, however, the authors added, “recent developments in psychological theory view the operator as an integral part of a man-machine system, and may well point the way toward increasing significantly the transfer effects of simulator teaching.” 

Jackson believes that simulation does help rewire the brain to think about what could happen on the road. He noted that simulation technology today, including graphics, sound, and tactile sensors can make the experience ultra-realistic. “As part of our scenarios,” he explained, “we’ll have a kid chase a ball in front of the car. Even in the simulator you get that same feeling of, ‘Oh my God, I just about hit a kid.’ You never want to experience that in real life.”

After a simulation-training surge in the 1950s and ‘60s, which included Drivotrainer exports to other countries like Great Britain and Sweden, driving simulator tech did not advance much and its use faded, although Aetnacars could still be found in some driver ed classrooms into the 1990s. Even as the US steered away from driving simulator classes for teens, they remained commonplace in parts of Europe, and companies that employ commercial drivers or certify them have continued to rely on driving simulators, even in the US.

But driving simulators for young drivers appear to be on the rise again in the US and across the globe, thanks to technological advances that have improved capabilities and reduced costs. Companies like Virtual Driver Interactive, Greenlight Simulation, and Drive Square offer immersive driving experiences that include combinations of surround monitors, virtual reality headsets, sound, and even full or partial vehicles mounted on motion platforms.  Video game developers have been getting in on the action, too, offering families a home-based experience. Valve Corporation offers Virtual Driving School for its popular Steam platform. And Driving XE offers Driving Essentials for Playstation and Xbox. 

Still, not all driving simulators are created equal. In a systemic review of driving simulator trials, researchers from Australia and New Zealand examined simulator fidelity—how accurately a simulator represents real-world driving. They concluded that most trials don’t include enough evidence to validate how well simulators compare to real-world driving, but they noted that significant advancements in simulator technology have led to a “wide variability in simulator design.”

According to Jackson, full-scale driving simulators like the one his team operates at CTI, offer the most immersive experience. “You’re in a real car,” he explains, “with real buttons. You can have the tactile sense. We even have a subwoofer under the seat so you get the vibrations of an engine.” Virtual reality, he notes, doesn’t offer such a realistic experience, but he thinks VR will have an important role to play in teen driver education because of its price point. Full-scale driving simulators can cost $500,000, but VR might be a few hundred dollars (even less for screen-based video game simulators), which could make driver education affordable again for high schools. Jackson notes that simulators can also help close income equity gaps. “For people who can’t afford a car,” he says, “simulators offer the ability to still have their teen learn how to drive and go through a driver education program.”

If you’re the parent of a teen who is about to take to the road, it might be worth looking at driving simulator training in your area, although your teen won’t receive any official accreditation toward earning a driver’s license. Still, while decades of data show that simulators are no substitute for real-world experience, they do have a positive impact on driving behavior. Plus, simulators today may be realistic enough to have an even greater impact than in the past. But if your teen tries to argue that all their hours logged on Gran Turismo or Super Mario Kart should count, don’t fall for it.

The Rivian R1S is an impressive technical tour de force, but it needs many improvements to warrant the $106,000 price tag.

That buzzy new restaurant that opened to rave reviews that you loved last year? What if you went back this year for a different dish, only to find that they’d raised their already-premium prices into the four-dollar-sign range? Worse, this time the food left you disappointed and thinking of another hot venue where the prices are lower. That’s where we are with the Rivian R1S battery-electric SUV. 

After driving the company’s debut model, the R1T pickup truck in 2021, and getting a preview drive last year of the latest example of the R1S SUV, PopSci got a chance to spend some real time with the that SUV, and unexpectedly, it left me hoping that Rivian’s chefs are open to some suggested improvements.

Rivian launched its business with the R1T pickup, guided by the observation that Americans buy more trucks than any other vehicle type. The R1S is the three-row family-hauling SUV follow-up that sensibly goes after another high-volume, high-margin market segment.

Rivian R1S design

The R1S’s panoramic skylight and third-row sunroof keep the large cabin awash in ambient light, preventing the cave-like effect that long, cavernous vehicles can suffer. The second-row seats are comfortable and their occupants will enjoy the climate control features like seat heaters that keep them happy.

The R1S's second row provides the expected amenities in a vehicle with a six-figure price tag, such as rear seat heating and cooling.

Things in the far-flung third row aren’t as good. Access is challenging, as it takes effort to scramble behind the second-row seats when they are flipped forward into the access position. The journey into the back row isn’t rewarded, as the seat bottoms are practically on the floor and there’s virtually no legroom. These seats are really only suitable only for children, but ones old enough to latch themselves into their booster seats so adults don’t have to clamber back there to do the job.

Rivian R1S motors and range

Apologies for getting down into the weeds now, but we need to establish some technical background for the R1S and R1T’s shared underpinnings. The original versions of the Rivian R1S SUV and the R1T pickup truck that we tested in 2021 are propelled by a quartet of costly electric motors sourced from Bosch. These motors each drive one wheel, providing exquisite computer-metered control of acceleration and regenerative deceleration.

They deliver a combined 835 horsepower and 908 lb.-ft. of torque, which boosts the Rivian to 60 mph in just 3.0 seconds. The 135-kilowatt-hour long-range battery pack is good for 321 miles of driving range.

Alas, the starting price for that version of Rivian’s EVs has risen from $67,500 at launch to $92,000 today for base models with the smallest-available battery pack. Rivian has developed its own in-house electric motors, dubbed “Enduro”, which cost less and make more power than the Bosch motors.

The company installs just two of these stronger motors in place of the four Bosch motors in its new Enduro R1S with a starting base price of $78,000 for the vehicle with the regular 260-mile battery pack and the normal-output dual Enduro motors. In this base configuration, the Enduro motors produce 533 hp and 610 lb.-ft. to push the R1S to 60 mph in 4.5 seconds.

The Dual-Motor Enduro powertrain drives the R1S’s four wheels using one motor in the front and one in the rear, each motor sending power to the right and left sides through a differential just like a combustion-powered vehicle would be. Like many gas-powered 4x4s, the Dual-Motor Rivians control wheelspin using a brake-based traction control system.

In a preview drive last year at Rivian’s Normal, Illinois factory, I got to try the company’s traction-testing mini-mountain. Just as when I drove it in Colorado in 2021, the Quad-Motor Rivian climbed the hill with supernatural capability. In comparison, the Dual-Motor version put some effort into the job of climbing the hill, with the brake traction control system audibly working to clamp down on wheels when they lose grip. The sensation is much like that of a capable combustion-powered off-roader.

Our Rivian R1S setup

This year’s R1S test unit was outfitted with the $16,000 400-mile Max Pack battery and the Performance version of the Enduro motors. This is only a software change from the base Dual-Motor Enduro R1S, unleashing the real capability of the drivetrain, which is 665 hp and 829 lb.-ft. Rivian charges $5,000 to remove the virtual shackles restricting the base model’s performance to accelerate the R1S to 60 mph in 3.5 seconds.

These add-on charges quickly add up, and in the case of our $78,000 base price test vehicle, the price snowballed to an eye-opening $106,000. For the so-called “lower-cost” version! The striking Canyon Red paint contributed $2,500 to that bottom line and the refined-looking Ocean Coast interior theme chipped in another two grand on the bill.

The optional 22-inch wheels added $2,500. The standard wheels are 21 inches, while the available off-road tire uses 20-inch wheels. This was the configuration of the R1T tested previously, and the difference is important.

The Rivian SUV’s cargo area is spacious and opens with a Range Rover-like split door, with an upper hatch covering most of the opening and a small lower tailgate providing convenient seating when open.

A bumpy test ride

That’s because the 22s on this vehicle don’t just boost the price to its astonishing total, but they also destroy the ride comfort of the R1S. This isn’t surprising, because larger wheels leave less tire sidewall rubber to cushion impacts. But it is surprising in the case of Rivian vehicles, because they employ the technologically amazing Tenneco cross-linked hydraulic suspension. It has the ability to precisely control the movement of each corner’s suspension.

McLaren Automotive uses the same system on its high-performance sports car to excellent effect. Those cars provide a comfortable ride despite their low-profile high-performance tires thanks to the hydraulic suspension. It seems like Rivian has not successfully exploited this capability.

This fact eluded me in the original test because that vehicle was fitted with the 20-inch off-road tires. But the problem with the 22-inch tires is best described by Rivian itself. The company issued an over-the-air software update in September that it says aimed to provide “reduced abruptness when driving over sharp road impacts in all drive modes, and reduced harshness when driving over bumps and dips at parking lot speeds.”

Those were admirable goals, but those exact problems remain. The Rivian’s ride is harsh, especially on sharp impacts, even small ones. Weather cracks in my street’s asphalt are overlooked while driving anything else. In the R1S, these nearly invisible cracks produce tooth-rattling jolts to occupants.

Neighborhood speed bumps are both harsh on impact and then poorly damped on rebound, when the compressed rear suspension springs back like a pogo stick after landing on the other side of the bump. A Ford Mustang Mach-E tested at the same time provided a positively cushy ride in comparison, with an as-tested bottom line price $10,000 lower than the Rivian’s elusive base price.

Rebound damping is also poor at highway speeds, as I noticed on the extended off-ramp of a nearby highway that has an unfortunate dip in the pavement that puts the spotlight on test cars’ rear suspension control. It revealed the Rivian to be the most deficient yet over this dip in the road.

Blame it on the computers

The hydraulic suspension is computer controlled, and there is the ability to switch between a stiff setting and a soft setting. In theory, this adjustability should mitigate the problems I encountered. In reality, differences were difficult to discern.

This was a theme noticed in other aspects of the Rivian’s computer controlled systems. Another that comes to mind is the following distance setting for the adaptive cruise control. Long or short, the distance is always too far and the difference between the two settings is slight.

Rivian’s automatic lane keeping system is a hands-on-the-wheel system, so don’t expect Ford F-150 Lightning BlueCruise-style hands-free driving on highways. It is a good example of a hands-on system, delivering the steering that the driver expects, unlike early systems that seemed to wrestle with the driver over the vehicle’s direction.

All such driver assistance systems rely on the vehicles’ perception systems, and the Rivian’s cameras watching the road ahead were confused by the white lines of liquid de-icer that had been applied to the road. Rivian’s instrument display shows what the vehicle thinks it sees, and the multitude of white lines in the lane left the R1S disoriented and yanking on the wheel at times when it thought it was crossing out of the lane.

Rivian R1S infotainment

Like so many EV startups, Rivian’s design aesthetic is minimalist, with few physical buttons or knobs. The R1S’s vertically oriented 16-inch central display provides access to most functions. Disappointingly, the convenient frunk open button we asked for in 2021 remains buried in on-screen menus rather than persistently situated in the tray of quick-access icons across the bottom of the R1S’s center display screen where drivers could instantly locate and use it. 

The minimalist interior design is clean and attractive, but the absence of physical buttons for some commonly used functions can be frustrating to reluctant early adopters.

Worse, as an SUV, unlike the R1T pickup we drove then, the R1S has a rear hatch that drivers will also want to be able to open quickly and easily. Again, no luck. The on-screen virtual button for the rear hatch resides alongside the frunk button within an on-screen menu.

Rivian does not support either Apple CarPlay or Android Auto, so phone integration is sub-par. Yes, you can pair your phone, but there’s no ability to operate apps on it while driving. Rivian also has no SiriusXM satellite radio receiver. The company has announced plans for an over-the-air update that will add a SiriusXM app to the infotainment system, at least.

This system will let drivers listen to SiriusXM by streaming it over the R1S’s cellular data connection and control the music on screen. The problem with that is that the music depends on a strong cellular signal. While streaming SiriusXM on my paired phone, I lost the signal while driving on an interstate highway 30 miles outside the nation’s capital. 

When the phone recovered the signal, the Rivian infotainment system did not resume playing music, so I was left to switch to an FM station until the next stop when I could restart the stream on the phone’s app.

Rivian’s onboard maps app does provide good turn-by-turn directions to often hard-to-find charging stations, which can seem to hide in a maze of strip mall parking lots and gas stations.

Charging challenges

Rivian anticipates that owners will head to the boondocks periodically, which is why the company is building the Rivian Adventure Network of company-operated EV charging stations on the way to outdoor destinations where DC fast charging options may be sparse. 

This is smart, but EV charging stations and cellular networks tend to have substantial geographic overlap. Acknowledging the shortage of EV chargers in outdoor areas is a reminder that drivers can reasonably expect there to be spotty cellular coverage, so a SiriusXM app will not work reliably when heading to the outback, while a satellite radio receiver would continue providing music.

When you need to use a DC fast charging station on a public charging network rather than charging at home, Rivian says the R1S will charge at a speedy 220-kilowatt rate, though the Rivian Adventure Network chargers top out at 200 kW.

I went to an Electrify America 350-kW charger and saw a peak charging rate of 50 kW. The battery’s state of charge was 63 percent and the battery temperature was 64 degrees F. This is relevant because EVs taper charging to slower speeds once the state of charge reaches 80 percent because it gets harder to stuff more electrons into a nearly full battery. That wasn’t the case here, and the slow charging also wasn’t because the battery was cold.

Charging at that rate, it would take hours to recharge an empty battery, which would blow up any thoughts of a tolerably quick road-trip top-off. Further, a visit to a brand-new EVgo charging station was a bust, because I couldn’t get the charger and the Rivian to cooperate. That’s when I diverted to the EA charger. A return visit to the EVgo charger later was successful, but when you need a charge, the fact that it might work next time is no help if it doesn’t work now.

Rivian claims an estimated driving range of 400 miles, and due to the wintry driving conditions, the R1S adjusted that estimate to a still-impressive 380 miles. Driving with 21-inch wheels would buy a few more miles because they are lighter than the tested 22s. The 20-inch wheels are a little worse because they only come with the off-road tires that have more rolling resistance.

My highway driving with the cruise control set on 70 mph produced a maximum range of 320 miles, which is still good, and far better than the Ford F-150 Lightning produced in similar conditions. Cruise control is beneficial during highway drives because it helps ensure smooth application of the accelerator. The R1S has adjustable levels of regeneration when the driver lifts off the throttle, but even the lower-level setting is very sensitive and can make it challenging to maintain a consistently steady speed for hours on end.

The high-regeneration mode can be too aggressive, even for a driver like me who appreciates the ability to slow the vehicle to a complete stop without using the brake pedal. It is helpful in stop-and-go traffic and for one-pedal off-road rock crawling, but the lower regeneration mode is better in everyday driving.

However, while it is easy to acclimate to the generally high level of deceleration when lifting off the accelerator, being used to it makes it more unexpected when that deceleration is absent. That’s what happens when you plug in at home for an overnight charge and the battery is fully charged.

With a full battery, there’s nowhere for the electrons coming from the electric motor/generators to go, so there’s no deceleration. It took an emergency stab at the brake pedal to stop the R1S from rolling past the stop sign at the end of my street the first time this happened.

However, when you’re going to do around-town driving and do not need an absolutely full battery, it is better to set the charging settings so that it stops when the battery is at 80 percent. This prolongs the life of the battery pack and also avoids those no-regen surprises.

Enter the R1S app

The R1S’s state of charge is one of the parameters that drivers can view and control using Rivian’s mobile phone app. The Rivian app is notably more responsive than others, especially Ford’s app, when it comes to simple functions like locking and unlocking doors, pre-heating the cabin, and checking or setting the battery charge level.

The app also lets you use the phone as a key, which proves to be surprisingly convenient. Rivian has a stylish key fob that resembles a climbing-gear carabiner that would be fine to use. Alternatively, the company also has a credit card-like card that provides access to the R1S and lets the driver start it. 

The phone app is so responsive that there’s really no downside to using it instead of the key fob for routine things. The only potential problem occurs when the driver drops his phone off for a new battery installation and then realizes that the plan to swing by the recycling dropoff location during the service is not possible because he doesn’t have the key fob and the phone has been disassembled. Oh well.

Who should buy the Rivian R1S?

The bottom line is that the Rivian R1S is an impressive technical tour de force that delivers genuine long-range driving on a single charge and the ability to carry the whole family. But the details of the suspension calibration, the on-screen functions, the absence of CarPlay, Android Auto, and a satellite radio receiver, and the slow battery charging make the purchase decision less obvious. 

The current pricing settles the question. The six-figure price tag for a vehicle that needs so many improvements makes an easy “no.” The Kia EV9 has appeared on the scene as an alternative three-row electric family SUV boasting a starting price of $54,900 and a “North American Utility of the Year Award.” That is the new benchmark in this vehicle segment.

Corrections 01/01/24 3:31pm: The navigation system is not Google Maps; it is Rivian’s own system. The starting price for the quad motor R1S is $92,000, not $95,000. This review has been updated to reflect this.

Lexus has given its GX SUV a major makeover, and not a moment too soon. The GX has a new engine, new suspension, and new technology, all on Toyota’s latest SUV and truck platform. With a new design that looks like its edges are carved from a hunk of shiny metal, the 2024 GX 550 looks sharper and more squared-off than the previous generation.

As the adage goes, however, looks are only skin deep. Lexus GX chief engineer Koji Tsukasaki would agree; when asked which came first, design or engineering, he emphatically says engineering.

“The platform was first, above everything,” he told PopSci.

The engineering team started with Toyota’s global GA-F platform and leaped off, building a capable and highly anticipated SUV on the way.

Stronger and lighter

In the lineup, the GX slots between the largest Lexus vehicles in the lineup, the LX and TX, and the smaller RX crossover. Less displacement plus turbo equals more power in 2024, and the numbers tell the story. The new GX is equipped with a 3.4 twin-turbo V6 engine generating 349 horsepower and 479 pound-feet of torque. That’s a big jump compared to the previous generation, which was powered by a 4.6-liter V8 engine capable of 301 horsepower and 329 pound-feet of torque.

It’s clear that Lexus is playing into the upward trend of overlanding/off-roading with this SUV. That goes double for the pair of new trim levels–Overtrail and Overtrail-Plus–which ride on fat 33-inch all-purpose tires and are equipped with settings made for dirt, sand, mud, and snow.

One of the ways they achieved that was by using non-linear tailor welded blanks, which are steel sheets of differing thickness and material, joined by laser welding and then press-formed. By pinpointing the weld points precisely where they’re needed most, the vehicle realizes substantial weight reduction while maintaining its rigidity. Trimming weight makes a difference: the new Lexus GX is about 750 pounds lighter than its target competitor, the Land Rover Defender 130. A Land Rover Defender 130 tips the scales at 6,415 pounds, while the new GX maxes out at 5,666. Lexus engineers intend for that to play out in better handling and maneuverability for on- and off-road use.

The biggest difference between the outgoing and new GX models is increased rigidity even with less weight, GX chief engineer Koji Tsukasaki told PopSci. Typically, he says, increasing rigidity adds weight, but the lighter frame and welding process balanced the scales. 

Electronic controls improve suspension

In many ways, the 2023 Lexus GX was old school, retaining its naturally-aspirated (non-turbo) V8 engine and outdated infotainment interface. The second generation of the SUV kicked off with the 2010 model and it has remained largely unchanged before the 2024 model, which will be available within the next couple of months.

Four-wheel drive remains a standard feature on the GX. While the previous generation of the GX included a kinetic dynamic suspension system (KDSS, for short), a mechanical system that adjusts front and rear stabilizers with interconnected hydraulic cylinders. For 2024, Lexus kicked up the suspension with an electronically controlled version the brand calls E-KDSS, available on the Overtrail and Overtrail-Plus trims. It uses sensors within the anti-roll bars in the front and rear to adjust the stabilizers, improving wheel articulation (which is what keeps all four tires in contact with the ground on uneven terrain).

The 2024 Lexus GX features Toyota's updated infotainment technology with a mix of physical buttons and touchscreen controls.

Stabilizer bars, also called sway bars, are a key part in a suspension setup, reducing the vehicle body’s roll and sway. Sway bars twist to keep the body flatter, putting more pressure on the outside tire to increase traction. And with this electronic adaptation, the system can activate the front and rear sway bars independently, which improves overall control.

“[The E-KDSS] detaches the stabilizer sway bar, allowing you even longer contact [on the ground],” Tsukasaki says.

The chief engineer says his team set out to give the GX what Lexus calls its “driving signature” so that the SUV feels like other vehicles in the lineup. Lexus is known for quiet, plush cabins and attractive exteriors, so the GX had to fit in even while adding more driving proficiency on more varied terrain. That’s not a simple matter for a body-on-frame vehicle like the GX. Body-on-frame refers to the construction of the vehicle, which brings the chassis and body together separately; a unibody (like the Land Rover Defender) is characterized by the chassis and body as a single unit.

Two or three times a year, Lexus hosts an event for all its vehicles’ chief engineers to come together and drive each other’s cars. From that, the engineers tweak things like reinforcements, wheel housings, and braces to ensure that every Lexus measures up.

“You could jump in any Lexus vehicle, and they should have that common driving signature, but to have that on a body-on-frame car was challenging,” Tsukasaki says. “We had to go back and adjust the chassis so [the GX] could accommodate that extra added feel that connects all of the vehicles together. That’s something we’re proud of.”

Apple’s long-delayed autonomous electric vehicle endeavor just got pushed back even further. According to a new report from Bloomberg, any chance of finally seeing a glimpse of the tech company’s top secret Project Titan car won’t happen until at least 2028, around two years later than Apple’s last estimated release window.

On top of kicking the car down the road (again), Apple’s ambitions to offer a fully driverless luxury vehicle have reportedly lowered significantly: company executives are now apparently willing to settle for a “Level 2+” system, an automation rating used by the global professional standards organization, SAE International. An Apple car classified at Level 2+ would hypothetically put its capabilities on par with Tesla’s currently available, much maligned Autopilot technology. When properly operating, a Level 2 or higher vehicle should be capable of assisting acceleration and brake controls, such as adaptive steering to stay within lanes, or a real-time responsive cruise control.

It’s a steep lowering of expectations from Apple’s early hopes of releasing a Level 5 car capable of driving “in all conditions… everywhere,” per SAE’s tier descriptions. Achieving the highest rating would ostensibly reduce drivers to passengers, with a car’s AI controlling all aspects of travel, without a human needing to take over responsibilities.

[Related: The first Tesla Cybertrucks have arrived.]

Apple’s vehicular aims date all the way back to at least 2014, when rumors of a project codenamed Titan or T172 first began circulating. Early designs reportedly nixed the inclusion of a steering wheel and pedals entirely, before eventually settling for somewhat more realistic goals. Even then, however, expectations for an industry redefining moment on par with the iPhone’s introduction have allegedly continued to temper over the subsequent years—despite being “one of the company’s most expensive research and development projects for the better part of a decade,” reported Bloomberg.

Since Titan’s inception, Apple has annually poured hundreds of millions of dollars into the project for engineering, closed road testing, cloud-based AI systems, and salaries. In 2021, Titan’s former project lead left the company, reportedly because he thought the car ultimately would never see the light of day. Apple then revised its release window the following year, at the time hoping to have a car ready for public reveal by 2026.

To this day, even the slightest hints of a prototype remain MIA, but Apple apparently could start making real headway now that it is eyeing much more achievable tech goals. Alongside its newest timeline, the company is reportedly considering additional management changes, as well as hardware and software engineering alterations.

By now, however, many at Apple allegedly view an EV rollout as ultimately being a “me-too product,” i.e. a vehicle that doesn’t set a new standard, as much as join a growing roster of sleek EVs. Currently, Apple’s biggest foray into automotives is CarPlay, onboard software that integrates iPhone features like Siri, maps, and music.

[Related: Apple may owe you some cash after settling a false advertising lawsuit.]

Say what you will about Tesla’s Cybertruck (seriously, say all that you will), but at least it is finally out in the real world. Even with revised hopes, it certainly seems like the prospect of seeing an actual Apple EV is further down the road than ever.

BMW is exploring ways to use Figure’s 5’6, 130-pound humanoid robot in its South Carolina manufacturing facility. Figure

Shiny, silver human-shaped robots the size of lightweight boxers are getting ready to start shuffling their way through BMW’s US factory floors. The carmaker recently reached a commercial agreement with the robotics startup Figure to bring its eponymously named “general purpose” humanoid robot to BMW’s manufacturing facilities, starting with its Spartanburg, South Carolina location. The agreement puts BMW in a race with Tesla and other automakers who’ve embraced a vision of humanoid robots in an effort to further automate their already tech-filled facilities. It’s clear the robots are coming, but nobody really seems to know exactly what to do with them just yet. 

How does the robot work?

The Figure robot is a 5’6, 130-pound bipedal hunk of metal capable of lifting around 45 pounds and walking up to 2.7 miles per hour. Figure, which aspires to make “the world’s first commercially viable general purpose humanoid robot” says its Figure 01 model can operate for around five hours before needing to recharge. Though it’s unclear exactly how the robot will work in an automobile factory setting, Figure believes its device generally will “enable the automation of difficult, unsafe, or tedious tasks.”

As to what the humanoid robots will be doing at the factory exactly, Figure spokesperson told PopSci that “tasks have yet to be announced publicly.” A BMW spokesperson said that the automakers are “investigating concepts.”

The agreement between BMW and Figure features multiple phases. At first, the companies will look to “identify initial use cases” for the robots. Once those are established, the robots will make their debut at BMW’s Spartanburg, South Carolina manufacturing facility. A BMW spokesperson from the company’s South Carolina facility told PopSci it’s investigating ways to use the humanoid robot in the facility and said it could prove useful in situations where two hands are needed to grip certain objects. The BMW spokesperson did not provide more specific use cases and said there isn’t currently a timetable for when the robot could arrive on site.

“BMW is always exploring the latest technology to make our processes more efficient. Companies that invest in innovation such as this are more sustainable, become more productive, and have a competitive advantage,” the spokesperson told PopSci. “We need the right tools for the future, and this is just one tool in our toolbox that can be used.”

A spokesperson for Figure, meanwhile, told PopSci their goal is to have robots perform in the BMW manufacturing facility sometime in 2024. 

Robots in car factories aren’t anything new, but up until now they’ve mostly resembled single-purposed machines only capable of performing specific preset tasks. Robotics manufacturers like Figure believe their new Humanoid robots, made in the image of humans, could act as a type of generalist able to walk a factory floor and perform various tasks. The inclusion of hands, for example, could help the Figure bot open doors and use tools. Arms and legs, meanwhile, could help the robot climb up stairs, traverse terrain, and lift heavy boxes.

“Single-purpose robotics have saturated the commercial market for decades, but the potential of general purpose robotics is completely untapped,” Figure Founder and CEO Brett Adcock said in a statement. “Figure’s robots will enable companies to increase productivity, reduce costs, and create a safer and more consistent environment.”

“Figure 01 brings together the dexterity of the human form and cutting edge AI to go beyond single-function robots and lend support across manufacturing, logistics, warehousing, and retail,” Figure notes on its website. 

Figure vaguely says it’s using AI to build “intelligent embodied agents” capable of interacting with real world environments in unique and unstructured real world scenarios. Recently the company released this video claiming to show the Figure robot using AI to learn how to make a cup of Keurig coffee after ingesting 10 hours of footage.

Carmakers are racing to bring humanoid robots to factory floors 

BMW’s new agreement with Figure comes around three years after Tesla announced its own plans to introduce artificial intelligence-enabled humanoid robots to its factory floors. At the time, Tesla’s robot was actually a dancing man wearing tight spandex. Since then Tesla has shown several prototypes of its “Optimus” robot which features a similar body design to the Figure model. The latest iteration of Optimus can reportedly squat and fondle eggs, but it’s still unclear exactly how that will translate to building cars. Tesla CEO Elon Musk previously told investors Optimus’ importance would “become apparent in several years” and even suggested the staggering machine could one day be worth more than Tesla’s automobiles. Tesla did not immediately respond to PopSci’s request for comment. 

Regardless of whether or not Musk’s predictions come true, other larger scale industrialists are taking note. In 2021, automating giant Hyundai completed an estimated $1.1 billion acquisition of Boston Dynamics, which is best known for creating odd videos of hulking humanoid robots performing backflips and various forms of calisthenics. Outside of the auto industry, Amazon recently revealed it was testing a bi-pedal humanoid robot from a firm called Digit which it said could one day work alongside employees in warehouses. 

So, why all the interest in robots now? Recent reporting from The Wall Street Journal suggests automakers like BMW see expanded automation through robotics as a way to offset rising labor costs and cut product prices. US autoworkers part of the United Auto Workers Union recently agreed to a new contract with Ford, Stellantis, and General Motors that includes a 25% wage increase over the course of four years. Other automakers like Toyota and Hyundai responded with their own wage increases. Humanoid robots, while costly to produce and untested in terms of reliability, could prove theoretically attractive investments for carmakers looking to offset rising labor–if they learn to outperform trained humans at making cars.  

Still, the sci-fi promise of a relentless, hyper efficient, never-sleeping robot workforce, for the time being at least, remains mostly speculative. Even Figure’s robot will reportedly have to walk itself to a charging station every few hours for a brief break.

Lincoln, Ford’s luxury arm, redesigned its Nautilus luxury midsize SUV for model year 2024. Updates include a distinctive flat-top two-spoke steering wheel and a new hybrid powertrain option, among other niceties. But the biggest news for the Nautilus is its giant, future-forward immersive panoramic infotainment screen.

Paired with a smaller touchscreen in the center stack, the panoramic display is set up to show an array of information the driver can customize. Important information like the speedometer and fuel gauge are in roughly the traditional spot behind the steering wheel. Important, but not critical information like tire pressure, weather, clock, and media are all pushed to the right side of the screen.

When the car is in Park, the driver also has access to gaming, video streaming apps, and soon, Ford says, video conferencing. The brand set out to build a customizable platform that can be inserted into a variety of vehicles, including future EVs. Knowing that EVs take longer to charge up than it takes to fuel a gas-powered car, the video apps seem to be a way to keep EV drivers distracted and productive while sitting at a charger. 

The panoramic setup, which sits atop the dashboard, is the highest-resolution display Ford–and by extension, Lincoln–has ever offered. Beyond the sheer size of the 48-inch-wide screen, the company went way beyond its comfort zone to create a digital experience unlike anything it has accomplished in the past. We’ve seen it, and it’s impressive.

Gaming tie-in

The squircle-shaped steering wheel is one way to access the SUV’s digital information, equipped with matching “d-pads” (directional pads) to navigate the controls. A d-pad is typically thumb operated and oriented like a plus sign, like a gaming console.

Upping the cool factor (but serving no readily apparent functional purpose), a real-time avatar spins in 3D on the touchscreen, matching the vehicle’s color and wheels. For this application, Ford tapped Unreal Engine to render it on the fly. Unreal Engine is a software framework and creation tool developed by Epic Games, the mastermind behind the wildly popular game Fortnite.

Ford’s gaming theme doesn’t stop there; it launched an exclusive version of the Asphalt Nitro 2 game, complete with a Shelby GT350R muscle car avatar. Gaming is limited to times when the vehicle is parked and can be played on the touchscreen or with any Bluetooth-capable controller. Bluetooth enables a keyboard connection to the screen as well, allowing vehicle occupants to use the Vivaldi freeware browser. Ford says it will transition to Google Chrome at some point in the future, and video conferencing apps are also on the table. These extend the work-from-anywhere option, allowing people to use their car as an office. The vehicle must be parked, not idling, to access any of these video-focused applications. 

Video streaming is now available with the new system on apps like YouTube, PBS Kids, and Amazon Prime; again, while parked. This could be a pleasant way to spend a few minutes in the parking lot while waiting for the kids to get out of school or in the cell phone lot at the airport, for example. At this juncture, riders in the passenger seat can’t watch videos while the car is moving. But Ford says it’s “definitely looking at it.”  

Software update

The panoramic screen is a showpiece for the software, which is now developed in-house at Ford. Director of Future Product, EV Digital Experiences and Services Zafar Razzacki says the development cycle began about two years ago, a long time in tech but a relatively short period compared to typical vehicle development.

“Bringing software in-house is a newer capability,” Razzacki told PopSci. “In the past, we typically relied on suppliers for hardware and software development. Bringing that in-house brings increased speed and quality and lower cost that we can pass on to the customer.”

General Motors caused a commotion last year by announcing its decision to go with a Google-based system, effectively eliminating access to Android and Apple CarPlay. Not so for Ford, which embraces the phone-mirroring applications for its customers’ Android and iOS devices. 

“We are very committed to offering a choice,” Christian Dodd, Senior Design Director on Ford’s digital teamsaid. “We have great relationships with Apple and Google.”  

For all platforms, Ford is encouraging the use of voice-assist controls, which helps to keep the driver’s hands on the wheel. Voice controls are typically laggy, however, discouraging widespread use. The company says it’s working to improve that latency, but that it sees a real benefit by using it more regularly. 

Organizations like AAA, however, have warned of the dangers of distracted driving from touchscreens and voice commands. We haven’t seen any laws on the books regulating in-vehicle screens or voice commands, but the data is startling. 

“Drivers using in-vehicle technologies such as voice-based and touch screen features were visually and mentally distracted for more than 40 seconds when completing tasks like programming navigation or sending a text message,” says the AAA Foundation for Traffic Safety

Even so, automakers are finding themselves in a race for the biggest and best screen. If they don’t, they risk losing sales to companies leaping ahead on the digital side. Ford says it’s cognizant of the dangers technology can post, and it’s actively working toward finding ways to make its infotainment as safe as it can. 

Balance between physical knobs and touchscreen controls is important on the safety side. Ford seems to be working toward finding that balance by implementing the d-pads and a large volume knob on the console that eliminates the multiple taps often required to make adjustments without physical controls. Figuring out what works best requires eye-movement tracking tests, both virtual and in the car, Dodd says. 

“There are going to be some features that require two to three clicks into the interface and the voice control will be more convenient,” Razzacki told us. “I think it depends on the application you’re using. You’ll see there are still some physical controls, like a big volume knob and d-pad controllers.”

New Lincoln owners will have to tackle a learning curve, and Ford is shoring up a video library along with dealership instruction at the point of sale. The brand says it’s exploring and learning, and will adapt to customers needs as they develop.

What is teledriving? Vay in Las Vegas
German startup Vay uses remote human ‘teledrivers’ to drop off rentable vehicles in Las Vegas, Nevada. Vay

Tourists and locals trekking near the Las Vegas strip this year will now see a new a fleet of SUVs mysteriously zooming across town without anyone in the driver’s seat. These vehicles, operated by German startup Vay, may not have humans grasping at the steering wheel but they also aren’t exactly the fully autonomous driverless cars of science fiction fame. In reality, the Vay cars are part of the emerging “teledriving” model where human operators use video-game-like remote controls to steer cars towards customers from the company’s headquarters. 

What is teledriving? 

Teledriving companies like Vay claim they can alter metropolitan mobility and one day reduce the number of cars filling city streets through the use of remote control drivers. Customers interested in using one of the vehicles request a ride on a mobile app. A team of human operators at Vay then use a combination of cameras, sensors and augmented reality tech to remotely drive a vehicle to the customer. Once the car arrives, the customers take over control and drive it to their destination with a fee based on time spent driving. When the trip is complete, the remote driver regains control over the vehicle and drives it to a new customer. PopSci has reached out to Vay to clarify what happens to the vehicles between trips and overnight.

Vay launched the first commercial teledriving product in the US last week in parts of Las Vegas, previously allowing for early access test drives. The company is operating its remote controlled car service near the city’s Arts District and the University of Nevada, which is nestled around a mile away from the famous strip. Users who take over the cars from the remote drivers are charged $.30 per minute while driving and $.03 per minute if they decide to momentarily park the car to go shopping or pick up groceries. 

The remote drivers at Vay operate the vehicles using a simulated driving station that looks like an advanced version of an arcade car game equipped with a physical steering wheel and pedals. A large screen reproduces the vehicle’s real-world surroundings using a combination of sensors and cameras. This is all made possible by modern 5G wireless networks, which let the vehicles quickly transmit real-time data to the remote operators. 

Vay isn’t the only startup trying to carve out a lane in the teledriving space but it’s the first to operate commercially in the US. Elmo, another major player in the space, recently received approval to operate in Lithuania. Together, these companies are hoping to attract commuters who want to save time parking vehicles and avoid the maintenance costs and responsibilities of owning a vehicle. Supporters of these shared, all-electric ride services say they could also help cut back on commuters’ carbon footprints by reducing the overall number of vehicles on the road. In 2021, the Environmental Protection Agency estimated around 29% of US greenhouse gas emissions were attributed to transportation, which includes light and medium duty cars and trucks. 

The jury is still out whether or no teledriving and more autonomous robots is services actually live up those climate-friendly claims. More traditional ride-hailing services like Uber and Lyft made similar promises, but data reportedly shows an increase in traffic congestion in most of the cities where they were introduced. Encouraging frequent, individual rides from teledriving services could also disincentive commuters to carpool, which studies show can reduce carbon emissions

Teledriving offers more peace of mind, but may have limited appeal 

Teledriving is the lesser-known, less flashy step-sibling to the fully autonomous taxis services offered by companies like Cruise and Waymo. Fully autonomous taxi services have inched closer to reality but collectively faced a setback last year after a series of high-profile missteps. Cruise, in particular, was forced to indefinitely cease its driverless taxi operations in California after one of its autonomous vehicles ran over a pedestrian. Another Cruise vehicle drove into wet cement

Those incidents likely won’t help autonomous vehicle companies gain favor among drivers, who still largely aren’t comfortably sharing the road with entirely driverless cars. A majority (63%) of US adults surveyed by Pew Research in 2022 said they would not want to ride in a driverless vehicle. Only 21% of respondents in that same poll said they would feel very comfortable sharing the road with an autonomous vehicle. 

Teledriving, by contrast, could provide riders some more piece of mind knowing a human is still guiding the seemingly driverless vehicle. Vay, in particular, calls its remote controlled experience an “alternative approach to autonomous driving.” 

“With teledriving, a human is in charge,” Vay CEO and cofounder Thomas von der Ohe said during a recent interview with CNBC. “This allows us to handle complex maneuvers such as unprotected left turns, emergency situations, and road works based on human perception and decision-making ability.” 

At the same time, teledriving firms’ decision not to fully embrace autonomous driving could limit its overall appeal. Commuters who summon these vehicles will still ultimately have to engage in the active and time-consuming act of driving. Commuters, in other words, won’t be able to take remote zoom video meetings or catch up on Netflix episodes in these cars. Teledriving also disincentivizes the ownership of personal vehicles, which many commuters value for its reliability and as a potential source of income down the line if they decide to sell. 
For now, at least, teledriving looks like an intriguing, if ultimately niche solution to a larger issue of accessible transportation in the US. Critics may argue this automobile focused approach could also distract from larger-scale efforts to invest in mass transit or cut back on overall time spent driving. Heightened safety concerns stemming from recent autonomous vehicle errors could offer teledriving companies slightly more runway, but it’s still unclear whether they will catch on in sprawling US cities anytime soon.

How some automakers are still pushing ahead for a hydrogen-powered future https://www.popsci.com/technology/hydrogen-powered-evs/ Wed, 17 Jan 2024 13:30:00 +0000 https://www.popsci.com/?p=598994

Last week at the massive Consumer Electronics Show in Las Vegas, some companies presented hydrogen as an alternative fuel star of the future. That may be a bit surprising, considering some headlines proclaimed that hydrogen is dead as late as last fall. Right now, the industry seems to be focusing its time and money on battery-electric power; hydrogen feels, at best, light years away from mainstream.

Several automakers have dabbled in hydrogen already, including Toyota with its smooth-riding Mirai and Hyundai’s Nexo. Audi, Honda, BMW, and others have explored it as well. Despite its challenges, several companies have dropped hints or outright pledged commitment to the development of this fuel option. 

The current administration’s commitment to clean energy has accelerated the process; in October, the U.S. Department of Energy announced a $7 billion investment to launch seven regional clean hydrogen hubs focused on producing low-cost, clean hydrogen. These hubs are strategically centered around the country, touching high priority areas in the Pacific Northwest central US, Midwest, East Coast, Appalachia, southern California, and the Gulf Coast of Texas. 

[ Related: A beginner’s guide to the ‘hydrogen rainbow’ ]

Honda is all in

Last fall, executive vice president of Honda Motor Company Shinji Aoyama told PopSci that a delicate balance exists between hydrogen supply and demand, and right now affordability presents a challenge for consumers. On average, hydrogen costs $13 to $16 per kilogram, which is roughly equivalent to two gallons of fuel. Currently, the national average for 87 octane gas (according to AAA) is about $3 per gallon, which means that hydrogen still costs more than double at the pump. 

That isn’t deterring the Japanese automaker, which says that solar and wind power are unstable on their own, as they are more susceptible to seasonality and weather conditions. By using renewable energy to generate hydrogen, it becomes a greener cycle.

“To ensure stable use of renewable energy, we need a means to store electricity that absorbs the impact of fluctuations in power generation,” said Honda executive (and 30-year Honda veteran) Arata Ichinose. “This is where hydrogen shows high potential as an energy carrier.”

Honda vouched for hydrogen energy back in the mid-90s, pledging time and money to research the possibilities. The company launched the world’s first fuel cell EV (FCEV) in 2002, refining it through subsequent iterations like the five-seat Clarity sedan. Even after the Clarity was discontinued, Honda built a fuel cell power station from fuel cells used in previously leased Clarity sedans, providing emergency backup power to the company’s data center in California. And they’re not finished yet: in 2024, the brand will launch an all-new FCEV based on the CR-V crossover.

Ramping up hydrogen infrastructure

While EVs continue to be the primary focus of the future for the automotive industry, American drivers continue to be concerned about the public charging infrastructure. That goes double (or tenfold, or even a hundredfold) for hydrogen vehicles, as hydrogen charging stations don’t exist outside of California. (Aside from one lonely station in Hawaii, that is.)

The federal government made some headway toward mitigating that issue last week, announcing $623 million in funding earmarked for battery-electric and hydrogen fuel-cell charging stations. About 11 percent, or $70 million, was set aside for the North Central Texas Council of Governments to build five hydrogen fueling stations. These facilities are intended to shore up the heavy trucking corridor between Texas and southern California and promote the exchange of business.

Truck and energy company Nikola showed off one of its first hydrogen cell electric trucks at CES last week as well. (The company’s previous all-electric efforts landed in hot water after a since-resigned CEO’s exaggerated claims.) Now, the company says its truck can achieve a range of up to 500 miles and fuel up in 20 minutes. Last year, Nikola moved its manufacturing headquarters 350 miles away from Cypress, California to a town south of Phoenix, Arizona. The mileage doesn’t add up, in either case, begging the question: How does a truck get from here to there without charging infrastructure?

In Nikola’s case, the trucks are packing their fuel to go. Portable fueling units have been mobilized to carry the energy needed with the plan to support up to 30 trucks per day. In the meantime, Nikola is partnering with Voltera (a company that builds EV infrastructure) to open six heavy-duty hydrogen stations in California thanks to a $42 million award from the California Transportation Commission.

German company Bosch believes that hydrogen power is necessary for a climate-neutral future, and it’s putting up $2.6 billion to develop and manufacture hydrogen. And it’s putting down big stakes, as Bosch’s stated plan is to generate sales of roughly $5.3 billion with hydrogen technology by 2030.

Hydrogen fuel cell challenges

The U.S. Office of Energy Efficiency and Renewable Energy describes hydrogen as a zero-emission clean fuel producing only water as a byproduct. Although that sounds ideal on the surface, hydrogen presents its own set of challenges especially as it relates to production and storage.

Hydrogen fuel can be produced through a handful of processes, including thermal, electrolytic, solar-driven, wind-powered, and biological reaction. Most hydrogen fuel cell centers are historically powered by natural gas, which doesn’t equate to green energy. Using methane to separate the molecules is widely used, but it poses a serious leak risk that can cause more harm than good. Renewables (wind- and solar-powered) methods are the greenest but one of the costliest options. 

Emre Gençer is a principal research scientist at the Massachusetts Institute of Technology (MIT) Energy Initiative, and he says of those four, only two can be used widely at a reasonable cost. One of those is using water electrolysis powered by electricity from renewable energy or nuclear power, and Bosch has a plan to advance that avenue.

Today, Bosch is feverishly developing components for electrolyzers, which use electrolysis (using direct electric current to drive a chemical reaction) to split water into hydrogen and oxygen. When used in combination with wind or solar power, the cycle creates a greener-yet cycle overall. The company says it “firmly believes in hydrogen as a future fuel” and it’s working on developing both stationary and mobile fuel cells.

Next, science will have to tackle the hydrogen storage conundrum. Hydrogen is low density and must be stored at high pressures to compress it to a usable volume, and it also requires super-low temperatures. While this aspect is still very much in development, automakers aren’t waiting idly by–especially with government funding backing the infrastructure. Solid state batteries are still on the table, and Toyota confirmed recently that it’s moving ahead with its plans to launch vehicles with this type of energy source soon. By this time next year, these technologies could be significantly more advanced.

Biden’s $623 million charging initiative faces struggles to get EVs over the finish line https://www.popsci.com/technology/biden-ev-charging-funding/ Thu, 11 Jan 2024 19:00:00 +0000 https://www.popsci.com/?p=598322

Stubbornly high EV prices, cheaper gas, and production setbacks complicate the U.S.’ embrace of electric vehicles.

A cross country US road trip in an electric vehicle might start to sound more appealing thanks to a fresh $623 million round of investment in EV charging networks from the Biden Administration. The new funds will inch the US towards Biden’s ultimate goal of 500,000 EV chargers nationwide by 2030 and help put to rest some riders’ fears of running out of juice mid journey. But infrastructure alone may not be enough to counteract slumping EV sales in recent months. Persistently high prices and drops in gas prices have left most Americans sitting on the fence when it comes to considering a new EV.  

The Biden Administration’s Department of Transportation announced the new funding on Thursday, which will come by way of grants sent to support 47 EV charging and alternative-fueling projects spread across 22 states and Puerto Rico. Those projects should lead to the construction of an estimated 7,500 EV charging ports, with many located in lower income and rural areas where charging infrastructure is still spotty. The latest round of EV funding stems from the 2021 Bipartisan Infrastructure law, which carved out $7.5 billion in total funds for charging infrastructure

“The public placed great trust in DOT, and we are honoring that trust by making improvements to transportation that get people and goods to where they need to be more safely, affordably, and sustainably while creating good-paying jobs,” DOT Secretary Pete Buttigieg said in a statement

Continuous investments in charging infrastructure are crucial to addressing range anxiety, one of the top barriers keeping drivers from switching over to electric vehicles. To that end, the administration claims publicly available EV charging ports have increased nearly 70% nationwide since Biden took office in 2021. That adds up to 161,562 total ports as of late last year, which works out to around a third of the administration’s goal of half a million chargers by the end of the decade

Additional government-funded charging ports can have less obvious psychological effects as well. Less than half (47%)  of US adults surveyed by Pew Research last year said they were confident the US government could build out the infrastructure needed to properly power electric vehicles nationwide. But those who did think the government was up to the task were also far more likely to say they would consider an electric vehicle next time they buy a car. Proper infrastructure support from the government, in other words, can make EVs seem more attractive to potential buyers. 

High up-front costs and cheaper gas present roadblocks 

But easy access to charging ports isn’t the only issue keeping EVs from flooding US highways. Despite years of technological innovation and government subsidies, most electric vehicles are simply too expensive for average buyers. Tesla, by far the largest seller of EVs in the US, made a dent in the average EV cost when it slashed its own prices, but consumers still lack much variety in terms of new electric vehicles under $50,000. A recent survey of global respondents by S&P Mobility listed affordability as the top concern slowing EV demand. Nearly half (48%) of those respondents said EV prices were simply too high. 

“Pricing is still very much the biggest barrier to electric vehicles,” S&P Mobility Senior Technical Research Analyst Yanina Mills said in the report. 

Slowing EV sales could, ironically, partly be explained by cheaper gas prices. EVs experienced a blockbuster year of adoption in 2022 when gas prices were soaring to upwards of $5 per gallon in certain parts of the US. Those inflated gas prices made switching over to an electric vehicle, even one slightly more expensive than an internal combustion alternative, more attractive. But prices fell back down to around $3 per gallon nationally last year, which some experts argue may have turned off some would-be EV buyers who were previously on the fence. 

Making matters worse, certain carmakers like Ford and Audi have also either scaled back production targets or delayed rollout of certain EV products citing the recent market trends. AutoPacific President and Chief Analyst Ed Kim recently told ABC News these factors and consumers’ recent attitudes towards EV’s means electric vehicles sales could top out around 1.5 million units by the end of 2024, a more reserved estimate than earlier, more optimistic predictions. 

“We’re not seeing the level of frenzied activity we saw earlier,” Kim told ABC. “There’s a slight tapering of demand and partially a market correction.” 

None of that necessarily means EVs are down for the count. Asking prices for less luxury focused EVs models are likely to continue dropping as carmakers ramp up manufacturing. Ford, the leading automaker by volume in the US, says it plans to produce 600,000 EV units annually by sometime next year. Other automakers have similar EV production ambitions. Cheaper upfront costs could similarly make slight variations in gas affordability less of a make or break consideration for drivers thinking about making a switch to EVs. 

 “The rate of adoption has tailed off a little bit but it’s still growing,” Kim added. “This is not a catastrophe for EVs.” 

EV charging availability alone won’t suddenly shift the vast majority of US drivers away from internal combustion engines, but a lack of that available will undoubtedly make that shift much harder. Instead, rapid EV adoption may likely rely on a careful combination of an expanded charging network, lowered upfront cost, and continuing shifts in overall demand.

Alphabet-owned Waymo says it’s ready to begin offering autonomous, “rider-only” trips on freeways in Phoenix, Arizona nearly 15 years after its founding. Waymo will take a multi-phased approach to freeway testing by initially restricting rides to employees as passengers before eventually opening the service up to customers using its Waymo One ride hailing app. That relatively methodical rollout follows months of trouble for the leading autonomous vehicle (AV) competitor Cruise, who was forced to freeze all operations in California last year following a string of safety concerns. 

Waymo, which already offers publicly available rides in parts of Phoenix, San Francisco, and Los Angeles, explained its plans for new freeway testing in a recent blog post. The company will use what it calls a “phased approach” where it will first offer “rider only” freeway commutes to Waymo employees in Phoenix. Employees will provide feedback on both the service and rider experience which Waymo says it will analyze before expanding rides to the wider public. Waymo did not provide any hard dates on when that expansion would occur, opting instead to say it would operate in a “step-by-step manner.” A Waymo spokesperson told PopSci that employees would begin taking these trips on freeways in Phoenix “in the coming weeks.”

“Before expanding, we ensure we have a comprehensive understanding of the environment we plan to operate and our system’s capabilities,” Waymo wrote in its blog post. “Waymo’s years of experience driving cars and trucks on freeways taught us to navigate everyday scenarios autonomously and inform our approach to responding to rare events safely.” 

The company says its gradual expansion to freeway rides could drastically cut down on some commute times where AVs would previously look for alternative, non-highway routes. Those brisker ride times could help address complaints from some critics who say AV rides can be frustratingly time consuming.

Waymo’s acceleration onto freeways comes just months after GM-backed Cruise, one of the top players in the AV space, was forced to freeze operations in California. In October, multiple vehicles from Cruise’s fleet of driverless Chevrolet Bolt’s were reportedly responsible for causing lengthy, frustrating traffic jams. Around that same time, another Cruise vehicle reportedly ran over a woman and dragged her after a hit and run driver collided with the pedestrian and flung her into the AV’s path. Another Cruise vehicle operating in San Francisco drove into wet cement. Those incidents and growing pushback ultimately ended with the California Department of Motor Vehicles suspending Cruise’s testing permits. Cruise froze all US driverless operations and CEO Kyle Vogt resigned. Regulators forced Cruise off the road before it could begin offering rides on freeways.

Over its years of development, Waymo has tried to distinguish itself from other competitors in the AV space by emphasizing its claimed commitment to safety over the Silicon Valley mantra of moving fast and breaking things. Last year, Waymo released a report laying out the “credible case for safety” where it explains the steps it takes to determine whether or not an AV system is safe enough to be deployed on a public road without a human driver. 

But freeway driving enters Waymo into new, potentially riskier territory. Unlike local city street driving, mistakes on freeways are more likely to run the risk of serious injury or death. And despite Waymo’s assurances that driverless cars are safer overall than humans, many everyday US drivers still aren’t convinced. 38% of US adults polled by YouGov last year said they feared widespread use of driverless cars on roads would increase the number of people killed in traffic accidents. That’s more than double (17%) the amount who believed driverless cars would reduce crashes.

General public queasiness around AVs makes commitments to safety and transparency all the more crucial. 63% of US adults surveyed by Pew Research in 2022 said they would not want to ride in a driverless vehicle, with another 45% saying they wouldn’t feel comfortable sharing a road with one. Almost everyone in that survey (87%) agreed driverless vehicles should have higher testing standards than regular vehicles.

How Nissan created brighter headlights that won’t blind oncoming traffic https://www.popsci.com/technology/nissan-anti-glare-brighter-headlights/ Mon, 08 Jan 2024 21:15:20 +0000 https://www.popsci.com/?p=597836

The brand’s engineering and design teams are working on new headlight patterns to make the roads safer.

It’s a staggering statistic: while only one-fourth of all driving is done at night, more than half of driver fatalities occur after dark. On top of that, says the American Automobile Association (AAA), more than three-quarters of pedestrian deaths happen at night.

Nissan says it is boosting headlight performance on its vehicles while simultaneously reducing glare for oncoming traffic. That’s certainly important all year, but especially during the darkest part of the winter months when rush hour typically happens after sunset. Once a luxury upgrade, Nissan now offers brighter, more efficient LED headlights standard on the Altima, Ariya, Armada, GT-R, Maxima, Murano, Pathfinder, Rogue and Z models.

This is how Nissan’s headlight engineering works.

Headlight technology continues to improve

To understand the current state of automotive headlights, look at both the evolution of headlight technology as well as regulations for the U.S. and abroad.

Halogen headlamps used to be the standard, giving way to LED (light emitting diode) lights starting in the mid-2000s. Audi was the first to debut all-LED headlights, on the 2009 Audi R8, and others followed closely behind.

The differences between halogen, high-intensity discharge (HID, or xenon) and LED are significant. Halogen lamps are much cheaper to make, and they emit a warm, yellow light. LEDs emit a cool, bluish-white light, plus they’re about 80 percent more energy efficient and last much longer. Nissan says this creates an unintended consequence as LED lights illuminate the road more clearly and further ahead, but they increase glare for drivers in the oncoming lane.

The Insurance Institute for Highway Safety (IIHS) started rating headlights in 2016. Out of more than 80 headlight systems available for the 31 models of 2016 midsize cars evaluated, only one system (the Toyota Prius v) received a top rating of “good.” For model year 2023, forty-three percent of headlight systems tested earned a top rating.

On a straight road, low-beam headlights qualify for a good rating when they illuminate the right side of the road at least 325 feet. At the other end of the scale, the Institute gives a poor rating (the lowest available) to those lighting 220 feet or less.

While LEDs are objectively brighter than halogen and HID varieties, the IIHS rates headlights using a set of performance metrics that are agnostic to the underlying technology, IIHS says. There are also examples of poor ratings for every type of headlight.

Nissan’s “anti-glare notch” 

Drivers employ low beams much more often than they do eye-scorching high beams. However, even low beams can cause a problematic glare for vehicles that are lower to the ground when a taller vehicle’s headlights are shining straight on.

Nissan’s newest focus is on creating a low-beam headlight that carves out an “anti-glare notch.” The brightest section of the beam aims toward the lane of travel, illuminating the way forward while the oncoming traffic sees a dimmer edge. Engineers create physical barriers within the headlight housing to direct the light in specific directions, and using LED instead of halogen lights offers better, crisper definition.  

Instead of a full “V” shape straight ahead typically cast by headlights, the silhouette of Nissan’s anti-glare headlight beam looks more like an amoeba. The resulting light makes it easier to see straight ahead and onto the shoulder of the road while still providing enough light to see into the oncoming traffic without blinding other drivers.

“We use computer-aided ray tracing to focus light with pinpoint precision, eliminating the need for bulky reflectors and projectors,” Brad Chisholm, an engineer on the exterior Lights, Mirrors and Wipers team at Nissan told PopSci. “The result is headlights that are thinner, sleeker, and more aerodynamic, all while bathing the road in bright, targeted illumination.”

Nissan says it’s excited about the future of adaptive beam headlights, which have been used in Europe for the last decade and were only recently approved for use in the U.S. This technology goes beyond automatic high-beam dimming by using cameras, sensors, and central processing units to adjust headlight brightness and beam shape. The brand says that moving to adaptive beam headlights will increase the benefits of the anti-glare notch by fine-tuning it in real time. 

Ultimately,  properly aligned headlights that intelligently illuminate the road will reduce the number of crashes and can save lives. Nissan’s work toward reducing the glare for oncoming traffic improves our odds even more.

The next frontier in EV battery recycling: Graphite https://www.popsci.com/technology/graphite-recycling-ev-batteries/ Fri, 05 Jan 2024 14:00:00 +0000 https://www.popsci.com/?p=597529

As more and more Americans embrace electric vehicles, automakers and the federal government are racing to secure the materials needed to build EV batteries, including by pouring billions of dollars into battery recycling. Today, recyclers are focused on recovering valuable metals like nickel and cobalt from spent lithium-ion batteries. But with the trade war between the U.S. and China escalating, some are now taking a closer look at another battery mineral that today’s recycling processes treat as little more than waste.

On December 1, China implemented new export controls on graphite, the carbon-based mineral that’s best known for being used in pencils but that’s also used in a more refined form in commercial EV battery anodes. The new policies, which the Chinese government announced in October shortly after the Biden administration increased restrictions on exports of advanced semiconductors to China, have alarmed U.S. lawmakers and raised concerns that battery makers outside of China will face new challenges securing the materials needed for anodes. Today, China dominates every step of the battery anode supply chain, from graphite mining and synthetic graphite production to anode manufacturing.

Along with a new federal tax credit that rewards automakers that use minerals produced in America, China’s export controls are boosting the U.S. auto industry’s interest in domestically sourced graphite. But while it could take many years to set up new graphite mines and production facilities, there is another, potentially faster option: Harvesting graphite from dead batteries. As U.S. battery recyclers build big new facilities to recover costly battery metals, some are also trying to figure out how to recycle battery-grade graphite—something that isn’t done at scale anywhere in the world today due to technical and economic barriers. These companies are being aided by the U.S. Department of Energy, which is now pouring tens of millions of dollars into graphite recycling initiatives aimed at answering basic research questions and launching demonstration plants.

If the challenges holding back commercial graphite recycling can be overcome, “the used graphite stream could be huge,” Matt Keyser, who manages the electrochemical energy storage group at the the Department of Energy’s National Renewable Energy Laboratory, told Grist. In addition to boosting domestic supplies, recycling graphite would prevent critical battery resources from being wasted and could reduce the carbon emissions tied to battery production.

To understand why graphite is hard to recycle, a bit of material science is necessary. Graphite is a mineral form of carbon that has both metallic and non-metallic properties, including high electrical and thermal conductivity and chemical inertness. These qualities make it useful for a variety of energy and industrial applications, including storing energy inside lithium-ion batteries. While a lithium-ion battery is charging, lithium ions flow from the metallic cathode into the graphite anode, embedding themselves between crystalline layers of the carbon atoms. Those ions are released while the battery is in use, generating an electrical current.

Graphite can be found in nature as crystalline flakes or masses, which are mined and then processed to produce the small, spherical particles needed for anode manufacturing. Graphite is also produced synthetically by heating byproducts of coal or petroleum production to temperatures greater than 2,500 degrees Celsius (about 4,500 degrees Fahrenheit)—an energy-intensive (and often emissions-intensive) process that triggers “graphitization” of the carbon atoms. 

Relatively cheap to mine or manufacture, graphite is lower in value than many of the metals inside battery cathodes, which can include lithium, nickel, cobalt, and manganese. Because of this, battery recyclers traditionally haven’t taken much interest in it. Instead, with many battery recyclers hailing from the metals refining business, they’ve focused on what they already knew how to do: extracting and purifying those cathode metals, often in their elemental form. Graphite, which can comprise up to 30 percent of an EV battery by weight, is treated as a byproduct, with recyclers either burning it for energy or separating it out to be landfilled.

“Up until recently, people talking about recycling for batteries really went after those token [metal] elements because they were high value … and because that recycling process can overlap quite a bit with conventional metal processing,” Ryan Melsert, the CEO of U.S. battery materials startup American Battery Technology Company, told Grist.

For graphite recycling to be worthwhile, recyclers need to obtain a high-performance, battery-grade product. To do so, they need methods that separate the graphite from everything else, remove any contaminants like metals and glues, and restore the material’s original geometric structure, something that’s often done by applying intense heat.

Crude recycling approaches like pyrometallurgy, a traditional process in which batteries are smelted in a furnace, won’t work for graphite. “More than likely you’re going to burn off the graphite” using pyrometallurgy, Keyser said.

Today, the battery recycling industry is moving away from pyrometallurgy and embracing hydrometallurgical approaches, in which dead batteries are shredded and dissolved in chemical solutions to extract and purify various metals. Chemical extraction approaches could be adapted for graphite purification, although there are still “logistical issues,” according to Keyser. Most hydrometallurgical recycling processes use strong acids to extract cathode metals, but those acids can damage the crystalline structure of graphite. A longer or more intensive heat treatment step may be needed to restore graphite’s shape after extraction, driving up energy usage and costs.

A third approach is direct recycling, in which battery materials are separated and repaired for reuse without any smelting or acid treatment. This gentler process aims to keep the structure of the materials intact. Direct recycling is a newer idea that’s further from commercialization than the other two methods, and there are some challenges scaling it up because it relies on separating materials very cleanly and efficiently. But recent research suggests that for cathode metals, it can have significant environmental and cost benefits. Direct recycling of graphite, Keyser said, has the potential to use “far less energy” than synthetic graphite production.

Today, companies are exploring a range of graphite recycling processes. 

American Battery Technology Company has developed an approach that starts with physically separating graphite from other battery materials like cathode metals, followed by a chemical purification step. Additional mechanical and thermal treatments are then used to restore graphite’s original structure. The company is currently recycling graphite at a “very small scale” at its laboratory facilities in Reno, Nevada, Melsert said. But in the future, it plans to scale up to recycling several tons of graphite-rich material a day with the help of a three-year, nearly $10 million Department of Energy grant funded through the 2021 bipartisan infrastructure law.

Massachusetts-based battery recycling startup Ascend Elements has also developed a chemical process for graphite purification. Dubbed “hydro-to-anode,” Ascend Elements’ process “comes from some of the work we’ve done on hydro-to-cathode,” the company’s patented hydrometallurgical process for recycling cathode materials, said Roger Lin, the vice president of global marketing and government relations at the firm. Lin said that Ascend Elements is able to take graphite that’s been contaminated during an initial shredding step back to 99.9 percent purity, exceeding EV industry requirements, while also retaining the material properties needed for high performance anodes. In October, Ascend Elements and Koura Global announced plans to build the first “advanced graphite recycling facility” in the U.S.

The Department of Energy-backed startup Princeton NuEnergy, meanwhile, is exploring direct recycling of graphite. Last year, Princeton NuEnergy opened the first pilot-scale direct recycling plant in the U.S. in McKinney, Texas. There, batteries are shredded and a series of physical separation processes are used to sort out different materials, including cathode and anode materials. Cathode materials are then placed in low-temperature reactors to strip away contaminants, followed by additional steps to reconstitute their original structure. The same general approach can be used to treat anode materials, according to founder and CEO Chao Yan. 

“From day one, we are thinking to get cathode and anode material both recycled,” Yan said. But until now, the company has focused on commercializing direct recycling for cathodes. The reason, Yan said, is simple: “No customer cared about anode materials in the past.”

That, however, is beginning to change. Yan said that over the past year—and especially in the last few months since China announced its new export controls—automakers and battery manufacturers have taken a greater interest in graphite recycling. Melsert also said that he’s starting to see “very significant interest” in recycled graphite.

Still, customers will have to wait a little longer before they can purchase recycled graphite for their batteries. The methods for purifying and repairing graphite still need refinement to reduce the cost of recycling, according to Brian Cunningham, the batteries R&D program manager at the Department of Energy’s Vehicle Technologies Office. Another limiting step is what Cunningham calls the “materials qualification step.” 

“We need to get recycled graphite to a level where companies can provide material samples to battery companies to evaluate the material,” Cunningham said. The process of moving from very small-scale production to levels that allow EV makers to test a product, “could take several years to complete,” he added. “Once the recycled graphite enters the evaluation process, we should start to see an uptick in companies setting up pilot- and commercial-scale equipment.“

Supply chain concerns could accelerate graphite recycling’s journey to commercialization. Over the summer, the Department of Energy added natural graphite to its list of critical materials for energy. Graphite is also on the U.S. Geological Survey’s list of critical minerals — minerals that are necessary for advanced technologies but at risk of supply disruptions. 

This classification means that domestically sourced graphite can help EVs qualify for the “clean vehicle credit,” a tax credit that includes strict requirements around critical mineral sourcing following the 2022 Inflation Reduction Act. To qualify for the full credit, EV makers must obtain a large fraction of their battery minerals from the U.S. or a free-trade partner. By 2025, their vehicles may not contain any critical minerals extracted or processed by a “foreign entity of concern” — an entity connected to a shortlist of foreign countries that includes China. This requirement could “drive a premium” for domestically recycled graphite, Lin said.

Tax incentives could be key to helping recycled graphite compete with virgin graphite, according to Yuan Gu, a graphite analyst at the consulting firm Benchmark Mineral Intelligence. Despite China’s new export controls, Gu expects graphite to remain relatively cheap in the near future due to an “oversupply” of graphite on the market right now. While Gu said that graphite recycling is “definitely on radar for Western countries” interested in securing future supplies, its viability will depend on “how costly or cheap the recycled material will be.”

If graphite recycling does catch on, industry insiders are hopeful it will be able to meet a significant fraction of the country’s future graphite needs—which are growing rapidly as the clean energy transition accelerates—while making the entire EV battery supply chain more sustainable.

“You can help regional supply chains, you can help with efficiency, with carbon footprints,” Lin said.  “I think it’s a no-brainer this will happen.”

Before Tesla’s CEO took the stage, pre-taped footage shown during the launch event included the Cybertruck traversing a variety of off-road vistas including a snowscape and sepia-filtered desert, idling in front of a cinematic sunset (or sunrise), towing SpaceX rocket parts, dramatically driving in circles, and being riddled with machine gun bullets. Later, per Newsweek, Musk told the audience, “In movies you sometimes see the hero or heroine hiding behind the car door while being shot with bullets. That doesn’t actually work unless you’re driving a Cybertruck. So, if Al Capone showed up with a Tommy gun and emptied the entire magazine into the car door, you would still be alive.”

The CEO delivered brief remarks before escorting the first 30 owners into their new electric vehicles, occasionally seeming to struggle with the handleless passenger side doors as smiling owners entered their new sharp-edged EVs. “It’s not just some grandstanding showpiece like me. It’s actually very useful,” Musk promised as the camera appeared to struggle to remain focused on the afternoon’s emcee. “How tough is your truck?” Musk rhetorically asked unnamed, rival carmakers, speaking into the direction of the audience. The challenge drew an enthusiastic response from dozens of attendees. Later, Musk repeatedly stressed the new, angular truck’s utility and durability.

During the Cybertruck’s official unveiling four years’ ago, Tesla vehicle designer Franz von Holzhausen hurled metal balls at a prototype to illustrate the EV’s “Armor Glass” enhancement, causing the driver side windows to shatter. Von Holzhausen demonstrated a similar exercise on Thursday afternoon, tossing a baseball at the Cybertruck twice. The windows did not appear to break this time.

[Related: Elon Musk says ‘we dug our own grave with Cybertruck’ ahead of its November release.]

“Here at Tesla we have the finest in apocalypse technology,” Musk declared to his excited fans at one point. Additional sizzle reel clips also highlighted the Cybertruck’s acceleration and towing capabilities. It apparently can outrace a 2023 Porsche 911 while towing an identical luxury vehicle for at least a quarter-mile.

“Experts said it was impossible,” Musk recounted of the Cybertruck’s design phase. Previously, critics have repeatedly voiced concerns about the Cybertruck’s potential safety issues and reports of numerous production woes allegedly costing Tesla billions of dollars. During an October 2023 earnings call, Musk cautioned shareholders and customers to “temper expectations” about Cybertruck’s initial profitability, adding that, “we dug our own grave with Cybertruck.” But here it finally was. 

Several tweets following the one containing yesterday’s livestream declared, “CAN’T WAIT! It’s basically the most badass car [that] ever existed! ❤️‍🔥🫶” and “LFG!!! Hope I can afford one.🤞🏻

When first announced in 2019, Tesla’s website briefly listed the Cybertruck’s estimated starting price as $39,990 before removing the amount. Now, its base model officially costs $60,990.

“It’s going to be amazing to see all these cars driving around,” Musk said near his presentation’s end as the 30 vehicles departed the showroom. “This is really going to change the look of the roads.”

A hybrid engine-motor combination boosts the torque on the latest-generation pickup truck.

Toyota finally gave the Tacoma pickup truck a glow-up in its fourth generation after eight years, including an important powertrain update: the Tacoma is available as a hybrid for the first time. 

First introduced for model year 1995, the Tacoma was equipped with a five-speed manual or four-speed automatic transmission matched with three gas engine options (four or six cylinders).  The Tacoma was 199 inches long and could tow between 3,500 and 5,000 pounds.

The 2024 Tacoma is 14 inches longer from stem to stern than the 1995 truck. It’s built on the same global truck platform as the Tundra (all new for 2022), Sequoia (which launched its third generation for model year 2023) and the redesigned Land Cruiser, unveiled earlier this year. 

And Toyota says the Tacoma’s new i-Force Max hybrid powertrain, offered as an option on the TRD Sport, TRD Off-Road, and Limited trims and standard on TRD Pro and Trailhunter variants, is the most powerful powertrain ever offered on a Tacoma. 

Take a look at the no-longer-secret recipe behind the 2024 Tacoma, including the new engine/motor combination. 

More torque, better off-road capability

The new Tacoma’s hybrid setup starts with the same 2.4-liter engine found in the gas-only trims. In the i-Force Max versions, a 48-horsepower electric motor sits between the engine and eight-speed transmission. If that configuration sounds familiar, it’s because Toyota equipped its Grand Highlander (launched earlier this year) with a 2.4-liter hybrid powertrain, too. The Grand Highlander Hybrid Max is the fastest and quickest in the lineup, providing 362 horsepower and 400 pound-feet of torque in the SUV.

In the new Tacoma, the hybrid setup produces 326 horsepower and 465 pound-feet of torque. That’s more than double what the original V6 could provide in the 1995 Tacoma; even more impressively, it’s significantly more than the 265 pound-feet in the outgoing 2023 model with a V6. Great torque numbers are essential for effortless off-roading, as the rotation helps the vehicle power up and over hills and boulders.

Some trims of the 2024 Tacoma are available with a multi-link rear coil suspension, replacing the leaf springs from the previous generation. Leaf springs are sturdy and preferred for more heavy-duty hauling, but the coil springs offer more flexibility and cushion for the ride. They’re a bit more expensive, which is why they’re an option on the higher grades. The three least expensive trims (SR, SR5 XtraCab and TRD PreRunner) will still come standard with leaf springs.

Tacoma fans know that the compact truck was already quite capable off-road, climbing rocks and hills like a mountain goat. However, after driving a 2021 model back to back with the new 2024 hybrid version, I can attest that the additional torque makes a noticeable difference. On an off-road course near Malibu, California, I scaled steep ascents and crawled over rock piles, and it’s clear that chief engineer Sheldon Brown and his team have smoothed out the edges. 

And it’s quieter, too

Toyota

A smoothed-out ride is even more clear on the asphalt. Tackling the twisty curves of Mulholland Drive, the interior of the Tacoma Limited was hushed, and Brown says technologies like active noise cancellation ensure a quiet cabin. This technology reduces the overall noise, vibration, and harshness, commonly referred to as an acronym: NVH. The study and adjustment of noise and vibration characteristics has become an art form, and Toyota put extra time and money into improving the in-cabin experience in the upper trims of the Tacoma. 

“We’re also using electronic sound enhancement, or ESE, to supplement what we’re hearing through the exhaust system,” Brown says. “We use specialized software that is paired with the exhaust type: the standard OE exhaust or you might choose our performance exhaust, which is an option. So it not only sounds good, but it cancels out any of those noises and vibrations that otherwise might make their way in.”

Some industry analysts have accused Toyota of taking too much time to get into the electrification stream, but the fact is that the Japanese company has been pumping out successful hybrid powertrains for decades. Now that the Tundra, Sequoia, and Tacoma are all available with an engine/motor combination, the 4Runner and Land Cruiser can’t be far behind.

Entry-level motorcycles too often feel like beginner bikes. Even if they don’t have training wheels, they have the vibe of first bicycles that are quickly outgrown and forgotten.

BMW has escaped this trap with the G 310 R, which is an ideal starter bike because of its affordable $4,995 price tag, its rider-friendly low seat that makes it easier to plant both feet on the ground, and its 349-lb. curb weight. The company even trimmed its regular $495 destination fee to $245 to help keep the price within reach for buyers on a budget.

BMW tells me that the G 310 R is a favorite at Motorcycle Safety Foundation’s Basic RiderCourse. It is easy to see why, considering the bike’s combination of racy styling and ease of use.

But anyone who decides to start out on a G 310 R shouldn’t feel like it is a temporary ride, waiting to be replaced by a “real” bike once the owner gains some experience. That’s because the G 310 R provides “real” big technology like standard anti-lock brakes (ABS) and a sophisticated suspension that includes an inverted fork for the front wheel and a long-wheelbase cast aluminum swingarm for the rear.

Inverting the fork (also called “upside down” forks”) bolts the heavy forks sliders into the triple clamps that secure them to the bike’s steering head, leaving the lightweight tubes to stretch down to the axle. That leaves the lighter tubes as the unsprung mass that has to travel up and down with the road surface while the heavier part is fixed in place. This contributes to more responsive front suspension.

Meanwhile, the lengthy swingarm to the rear axle lends the bike greater stability compared to a short swingarm.

The value of anti-lock brakes should be self-evident, but to recap, the BMW’s computer prevents riders from locking a wheel under heavy braking. In a car, this produces a slide and prolongs stopping distances. On a bike, if the front wheel locks, it tends to immediately slip to one side or the other and pitch the rider to the ground. 

If the rear wheel locks, the bike will start to slide sideways. Riders’ typical response to this is to release pressure to the rear brake. Doing so while the bike is not pointed in the direction of travel when the rear tire regains traction causes the bike to catapult the rider off in a spectacular and painful “high side” crash.

ABS is worth its weight in cryptocurrency because it prevents both kinds of crashes by ensuring that the wheels keep turning until the bike comes to a complete stop. It is also important because most riders, when faced with a potential crash, fail to apply the brakes hard enough. Ideally, knowing that they can’t lock the brakes will encourage more riders to brake harder so that maybe more of them will stop short of hitting the obstacle ahead.

Regardless, riding the Cosmic Black G 310 R test bike was enough fun to put such sober considerations in the background. I had the opportunity to test it alongside BMW’s sexy S 1000 R and I can confirm that the smaller bike held its own while slicing through mountain switchbacks, courtesy of its advanced suspension and light weight.

It also highlighted the G 310 R’s user-friendliness. While the S 1000 R has a very abrupt clutch friction point and brakes that grab aggressively with the slightest application of pressure (very much like Ferrari’s brakes), the G 310 R has a wide, easy-to-engage clutch friction point and brakes that grip progressively, making it very easy for even beginning riders to pull away from a stop and then arrive at the curb like pros instead of the amateurs they are.

Like most of today’s generation of starter bikes, the G 310 R has only one cylinder in its 313-cc engine, when earlier small bikes would have had smoother-running twin-cylinder engines. But the BMW’s 34-horsepower single incorporates a counterbalancer, so it revs to its surprisingly high 9,500-rpm redline with unexpected smoothness. This makes it easier to keep the engine spinning out as much power as possible while clicking through the six-speed transmission, letting the G 310 R feel adequately powerful.

The bike’s engine has an unorthodox configuration, with the cylinder tilting rearward like the back half of a Harley-Davidson V-twin. As with the Harley’s rear cylinder, that puts the BMW’s intake system in front, with the exhaust pipe trailing off the rear, which is the opposite of most single-cylinder bikes.

The rear-leaning cylinder lets the bottom of the engine and the heavy transmission shafts that live there slide forward, shifting the bike’s balance onto the front wheel for greater stability. It also clears space behind the transmission for the aforementioned long rear swingarm.

All of this speaks to the benefit of rethinking the engineering challenge from the beginning of a project and dismissing convention to deliver a superior result. The G 310 R is fun to ride for riders of all levels, not just beginners. But it treats them especially well, just as the Motorcycle Safety Foundation’s rider’s school. The BMW engineer team should be proud of their clever solutions to creating an affordable bike that is a true BMW.

After three years of construction and limited operations, the next-generation Hyundai Motor Group Innovation Center production facility in Singapore is officially online and fully functioning. Announced on November 20, the 935,380-square-foot, seven-floor facility relies on 200 robots to handle over 60 percent of all “repetitive and laborious” responsibilities, allowing human employees to focus on “more creative and productive duties,” according to the company.

In a key departure from traditional conveyor-belt factories, HMGIC centers on what the South Korean vehicle manufacturer calls a “cell-based production system” alongside a “digital twin Meta-Factory.” Instead of siloed responsibilities for automated machinery and human workers, the two often cooperate using technology such as virtual and augmented reality. As Hyundai explains, while employees simulate production tasks in a digital space using VR/AR, for example, robots will physically move, inspect, and assemble various vehicle components.

[Related: Everything we love about Hyundai’s newest EV.]

By combining robotics, AI, and the Internet of Things, Hyundai believes the HMGIC can offer a “human-centric manufacturing innovation system,” Alpesh Patel, VP and Head of the factory’s Technology Innovation Group, said in Monday’s announcement

Atop the HMGIC building is an over 2000-feet-long vehicle test track, as well as a robotically assisted “Smart Farm” capable of growing up to nine different crops. While a car factory vegetable garden may sound somewhat odd, it actually compliments the Singapore government’s ongoing “30 by 30” initiative.

Due to the region’s rocky geology, Singapore can only utilize about one percent of its land for agriculture—an estimated 90 percent of all food in the area must be imported. Announced in 2022, Singapore’s 30 by 30 program aims to boost local self-sufficiency by increasing domestic yields to 30 percent of all consumables by the decade’s end using a combination of sustainable urban growth methods. According to Hyundai’s announcement, the HMGICS Smart Farm is meant to showcase farm productivity within compact settings—while also offering visitors some of its harvested crops. The rest of the produce will be donated to local communities, as well as featured on the menu at a new Smart Farm-to-table restaurant scheduled to open at the HMGICS in spring 2024.

HMGICS is expected to produce up to 30,000 electric vehicles annually, and currently focuses on the IONIQ 5, as well as its autonomous robotaxi variant. Beginning in 2024, the facility will also produce Hyundai’s IONIQ 6. If all goes according to plan, the HMGICS will be just one of multiple cell-based production system centers.

The SUV market is big business, especially in the United States. Even supercar manufacturers like Lamborghini are making five-seat SUVs and thriving. Aston Martin’s DBX crossover represents roughly half of its overall sales. And that’s only on the gas-powered side. All-electric SUVs are just starting to find their groove, and vehicles like the three-row Kia EV9 SUV and Volkswagen ID.Buzz “microbus” are on their way to the U.S. market in 2024. Now, emerging luxury EV builder Lucid just announced the Gravity, a seven-seat SUV with an astonishing claim of 440 miles of all-electric range.

The SUV boasts other niceties like acceleration from zero to 60 miles per hour in less than 3.5 seconds, 1,500 pounds of payload (what it can carry inside) and the ability to tow 6,000 pounds. To compare, Tesla’s Model X can tow 5,000 pounds, haul 1,065 pounds inside the vehicle, and can go for 348 miles with the long-range package.

Here’s how Lucid is pushing other EV automakers to increase range and capability.

Gunning for Tesla

Lucid started producing its first model, the Air, in 2021 after more than a dozen years developing battery technology. Launched with 520 miles of EPA-estimated all-electric range and up to 1,111 horsepower, the Air earned rave reviews from users and journalists alike. Luxurious and uncommonly aerodynamic (more about that below), the Air’s starting price is roughly the same as a Tesla Model S. However, the Lucid model gets 115 more miles of range and  91 more horsepower than the Tesla.

If it sounds like an intrastate basketball rivalry, it may be partially attributed to the cross-pollination across the executive level. Before joining Lucid in 2013, CEO Peter Rawlinson spent three years at Tesla as a top engineer. Rawlinson led the engineering team for the Model S; when he left Tesla, he emerged swinging with the Lucid Air sedan. 

The company’s latest accomplishment is the Gravity SUV, and Lucid says “it can achieve 440 miles of range with a battery pack a little more than half the size of some of our battery-hungry competitors.” For context, a GMC Hummer EV’s battery pack alone weighs in at a hefty 2,818 pounds on the GM’s Ultium platform. 

The entire Lucid Air weighs 5,203 pounds and the Gravity is expected to tip the scales north of 6,000 pounds. Sure, it’s relatively heavier than some three-row SUVs such as the Kia Telluride and Lexus GX, but it’s on par with others like the Grand Wagoneer.

Advanced battery technology 

Carrying two electric motors, the Gravity is touted as more efficient than its competitors. Rawlinson says the Gravity’s smaller and lighter technology battery pack means consuming fewer precious metals and minerals and results in less energy to charge and less pressure upon the grid. 

The Lucid Air is available with two battery packs–92 kilowatt hours or 112 kilowatt hours–and while Lucid is being vague about its exact specs for now, we expect the Gravity to utilize the larger 112 kWh version. For scale, the GMC Hummer EV and Cadillac Escalade IQ use packs over 200 kWh. 

Justin Berkowitz, Lucid’s senior manager for technology PR, says the company offers “the most efficient electric motors on the market and ultra-high voltage power electronics (over 900 volts compared to many EVs at 400-500).” All of these are designed, patented, engineered, and manufactured in-house by Lucid, and the company also develops the software powering it all. 

The stellar range is also a result of Lucid’s proprietary winding technique that produces a denser magnetic field along with several other innovations that create a super-compact package. The company holds eight patents related to the motor’s windings and cooling, and continues to find ways to squeeze as much copper into the motor stator as possible to generate big energy in a small package.

Aerodynamics are also a key, and Lucid says the Gravity has a drag coefficient of under 0.24. The lower the number, the more efficient the result. Hyundai’s three-row gas-powered Palisade has a 0.33 coefficient of drag, and the upcoming Kia EV9 hits 0.28. Tesla says its Model X sits at 0.24, so Lucid is sliding just below that with the Gravity. It’s still not as aerodynamic as the five-passenger Hyundai Ioniq 6, which has an impressive 0.21 drag coefficient. Give them time, though. Lucid is poised for major growth.

Cruise CEO Kyle Vogt announced his resignation from the controversial robotaxi startup on Sunday evening. The co-founder’s sudden departure arrives after months of public and political backlash relating to the autonomous vehicle fleet’s safety, and hints at future issues for the company purchased by General Motors in 2016 for over $1 billion.

Vogt’s resignation follows months of documented hazardous driving behaviors from Cruise’s autonomous vehicle fleet, including injuring pedestrians, delaying emergency responders, and failing to detect children. Cruise’s Golden State tenure itself lasted barely two months following a California Public Utilities Commission greenlight on 24/7 robotaxi services in August. Almost immediately, residents and city officials began documenting instances of apparent traffic pileups, blocked roadways, and seemingly reckless driving involving Cruise and Google-owned Waymo robotaxis. Meanwhile, Cruise representatives including Vogt aggressively campaigned against claims of an unsafe vehicle fleet.

[Related: San Francisco is pushing back against the rise of robotaxis.]

“Anything that we do differently than humans is being sensationalized,” Vogt told The Washington Post in September.

On October 2, a Cruise robotaxi failed to avoid hitting a woman pedestrian first struck by another car, subsequently dragging her 20 feet down the road. GM issued a San Francisco moratorium on Cruise operations three weeks later, followed by a nationwide expansion of the suspension on November 6.

But even with Cruise on an indefinite hiatus, competitors like Waymo and Zoox continue testing autonomous taxis across San Francisco, Los Angeles, Phoenix, Austin, and elsewhere to varying degrees of success. As The New York Times reports, Waymo’s integration into Phoenix continues to progress smoothly. Meanwhile, Austin accidents became so concerning that city officials felt the need to establish an internal task force over the summer to help log and process autonomous vehicle incidents.

[Related: Self-driving taxis allegedly blocked an ambulance and the patient died.]

In a thread posted to X over the weekend, Vogt called his experience helming Cruise “amazing,” and expressed gratitude to the company and its employees while telling them to “remember why this work matters.”

“The status quo on our roads sucks, but together we’ve proven there is something far better around the corner,” wrote Vogt before announcing his plans to spend time with his family and explore new ideas.

“Thanks for the great ride!” Vogt concluded.

The first practice run lasted less than 10 minutes after Carlos Sainz’s Ferrari encountered a literal bump in the road, with the race halted for several hours.

A litany of issues has plagued Formula One’s highly anticipated (and derided) Las Vegas Grand Prix race for months, but the event’s most recent issues are perhaps its most ridiculous yet—the cars on-average 212 mph speeds are too fast for the Vegas Strip.

F1 racers can’t bolt down any standard roadway—they require specialized, carefully laid pavement. America’s other two F1 venues in Austin, Texas, and Miami, Florida, were both built specifically for the high-speed races, but the Las Vegas Grand Prix circuit presents a wholly different challenge, as it is located within the city itself. To prepare for this weekend’s competition, workers first removed the route’s top 5-to-10 inches of asphalt before replacing it with 60,000 tons of a base layer followed by another 43,000 tons of intermediate and top layer pavement.

Speaking to The Washington Post on Thursday, Las Vegas Convention and Visitors Authority chief executive Steve Hill estimated the new circuit pavement would last 6-10 years, and only need piecemeal maintenance without requiring extensive road closures.

But according to event organizers on November 16, F1 drivers’ first, late evening practice run barely lasted eight minutes before abruptly being forced to end. Near the track’s final corner, racer Carlos Sainz suddenly stopped, reporting apparent damage to his Ferrari’s flooring. A quick investigation of the track revealed that the race car’s speed and accompanying force put too much stress on a drain cover’s concrete framing, causing it to protrude and significantly damage the Ferrari’s chassis—the main frame to which its engine and suspension are attached. If that weren’t enough, racer Esteban Ocon’s car received a similar blow from the dislodged debris shortly after Sainz.

[Related: How the Formula races plan to power their cars with more sustainable fuel.]

This isn’t the first time grates proved to be an F1 car’s Achilles heel—another vehicle suffered a similar fate at a practice during the 2019 Azerbaijan Grand Prix. In that instance, however, F1 organizers welded shut the track’s coverings—a solution unavailable to last night’s crew members since it’s illegal to do so under Nevada law. Instead, repairers raced (so to speak) down the Las Vegas track, applying quick-setting concrete to the remaining 20-to-30 coverings.

It was 2:30am local time before racers could return for a second practice run. By this point, they raced past attendee stands devoid of any fans. Labor laws prevented security workers from continuing to staff the event. Those who attempted to stick it out to see the racers return were forced to leave for the night around 1:3gett0am. The competitors completed their trial runs without further incident.

Both drivers and their team members haven’t minced words since the evening’s debacle. Belgian and Dutch racer Max Verstappen described the Vegas Grand Prix as “99 percent show and 1 percent sport,” while Ferrari boss Fred Vasseur called the incident “unacceptable.”

“The situation is we damaged completely the monocoque, the engine, the batteries. I’m not sure this is the topic for me today,” Vasseur told reporters at the time. “We had a very tough [first practice], it cost us a fortune, we fucked up the session for Carlos.”

Mercedes chief Toto Wolff, however, defended the race and described the issue as a “black eye,” but nothing else. “This is nothing… they’re going to seal the drain covers and nobody’s going to talk about that tomorrow morning anymore,” Wolff continued.

Car seats, like the vehicles themselves, are available in a variety of materials with a wide range of manual and electronic controls. My old 1977 Dodge Aspen, for instance, had a front row bench seat that moved as one, like a faux-brocade couch on rails. It had no ventilation, no heat, and definitely no massaging functions. Automobile seating has come a long way since then. 

The first production car with optional heated seats was the 1966 Cadillac DeVille, and massaging seats came along decades later in 2000 Mercedes-Benz and Cadillac models. Bentley, however, has taken the spa-like cabin to the next level with its available “airline seat specification” setup; the British brand says its super-deluxe airline seat specification is a world first.

This $11,000 option in the extended wheelbase version (EWB) of the Bentayga includes not just heat, but cooling, massage, recline, and small trays that fold out like those on a commercial airline. This SUV’s seats even have sensors that predict that you’re about to start sweating even before you know it yourself and preemptively adjusts the temperature. 

Here’s how they work.

First class seats

When travelers on an airplane upgrade to business or first class, they gain a significant amount of legroom and space around their seat. Bentley chose to call this Bentayga EWB setup “airline seat specification” to drive home the message that this is a roomy, first-class experience. As soon as you sit down, the sheer number of positioning options is dizzying: The rear seats can be adjusted 22 ways, not including the rear footrest behind the front passenger seat. 

Steve James, the head of interior design for Bentley, has been developing seating for the luxury brand since 2006. His first task when he joined Bentley was to come up with the initial concept for the seats in Bentley’s then-new flagship model, the Mulsanne. While the uber-luxurious Mulsanne model included heated, cooled, and massaging seats, the Bentayga EWB says “hold my Dom Perignon” and ratchets it up even more to prevent fatigue, not just treat it.   

“High-end cars focus quite a lot on fatigue recovery; if you’re getting tired in the car, the massage function is designed to help after the fact,” James says. “But we thought the real luxury experience is to do something to stop the fatigue in the first place. We saw an opportunity with the Bentayga EWB because we have more room to work with.” 

Science, research, and “perfect posture” 

James explains that Bentley focused on two key metrics during the development of the first-class seats: posture and thermal response. Bentley collaborated with an American chiropractor and Comfort Motion Global (CMG), a company that partners with research universities to test its proprietary technologies. Through its research, it discovered that making small adjustments in the leg and back angles of a vehicle seat–as little as one to two degrees–results in a positive increase of blood flow, increasing alertness and reducing fatigue. 

Bentley’s seats are fitted with 12 electric motors and three pneumatic valve engine control units. Unique algorithms developed in conjunction with CMG apply 177 individual pressure changes, shifting stress points from one area to another to stop the onset of fatigue. And the leg rest feature in the Bentayga is situated at a particular angle to create what James calls “perfect posture” that bends the legs slightly for maximum comfort and blood flow. 

“As you may have experienced if you’re in a plane or sitting statically for a long period of time, fatigue sets in,” James says. “The postural system is a system of pneumatic bladders inside the seat and they make small micro-adjustments that fine-tune the angles of your pelvis, your thighs, they are helping motion constantly happen. Small motions that give the customer the option to regulate them. They really make a difference.”

Temperature

Another important element of Bentley’s high-end seats is what it calls “thermal comfort.” (There is a default calibration, but it can be adjusted depending on the average temperature preference of the passenger.)

Bentley embedded two sensors in the seats, each constantly measuring humidity and temperature levels of the bottoms and backs of the seats. With that data, the car can automatically activate its seat climate system for heating or ventilation to maintain the passenger’s individual comfort level. James says that the system detects temperature variations of 0.1 degrees and registers upward and downward trends and the human brain doesn’t notice before the delta is 0.5. So the seats’ constant monitoring heads off perspiration before it even happens.

While the concept started to take shape in 2015, the brand didn’t create a working prototype until 2019 after years of data collection and validation. The team had to do quite a bit of calibration on the thermal comfort side, as different passengers feel comfort at vastly different temperatures depending on a number of factors. And as it turned out, one of the engineers became a real-time case study; he became ill during the development and started feeling hot and sweaty. As designed, the system measured that and calculated the delta in his calibration preferences. 

“The real clever bit of the system is it can sense even to one-tenth of a degree Celsius at all times,” James says. “It can measure how you’re feeling and how your temperature is trending. So if you start feeling a little bit warm or perspire a bit–we can actually see it before you feel it.”

In a mainstream car with heated seats, you might find that activating them to full power feels wonderful in cold temperatures until you start overheating. At that point, the seats hold residual warmth that feels uncomfortable until it cools off. Bentley’s seats are designed for an ideal balance of hot and cool so that you feel consistently content.

How do electric cars work? By harnessing the magic of magnetism. https://www.popsci.com/technology/how-do-electric-cars-work/ Sat, 11 Nov 2023 12:00:00 +0000 https://www.popsci.com/?p=588757

From the battery system to regenerative braking, these are the basic technologies that power EVs.

The post How do electric cars work? By harnessing the magic of magnetism. appeared first on Popular Science.

To understand how electric cars work, it helps to keep in mind the ways in which they’re similar to regular gas-burning vehicles. They’re cousins from different generations, not machines from different universes. If you drive, you know the drill: Press down on the pedal with your right foot to get moving, point the vehicle where you want to go, maybe put on some music, and try not to crash. 

“An EV has four wheels,” says Chad Kirchner, the founder of evpulse.com, a news and information site about electric vehicles. “There’s a start button, there’s an accelerator pedal, there’s a brake. In a lot of ways, an EV—and the EV driving experience—is identical to a gas-powered experience.” 

That said, there are key differences in engineering, design, maintenance, and performance between electric cars and internal combustion engine (ICE) vehicles.   

Electric car battery system 101

To begin with, an ICE vehicle relies on a tank of gasoline or diesel to get the energy it needs. An EV, on the other hand, requires a battery system, which consists of a multitude of individual cells. And just like a gas tank, the battery cells store energy. 

“But [a battery cell] also produces power—and the power is a result of the voltage of that particular cell, and the current it’s able to output,” says Charles Poon, the global director of Electrified Systems Engineering at Ford, which makes the Mach-E, the F-150 Lightning, and the E-Transit electric vehicles. He describes the battery as the car’s heart.

Battery design in EVs will differ between automakers, and one of the main ways is the shape of their cells. To make things a bit more tangible, consider the Mach-E, an electric car that descends from a famous line of gas-burning vehicles that gave birth to the term “pony car.” The cells in the Mach-E are in pouch form, whereas other batteries in the market have cylindrical cells (Tesla uses those) or prismatic cells. A Mach-E battery system has hundreds of cells.

The lithium-ion-based electric car batteries can also have slightly different chemistries. For example, a Mach-E can come with nickel, cobalt, and manganese (NCM) batteries or lithium iron phosphate (LFP) batteries. The former are known for being able to hold power for longer and performing well in cold temperatures, while LFP batteries are less expensive and can charge up faster.

How do electric motors work? 

The term AC/DC is not only the name of an Australian rock band, but also describes two forms of electricity: alternating current (AC) and direct current (DC). Both types of power are important for electric cars to work.

The electricity coming out of your wall outlet at home is in AC form, but batteries store their energy in DC form. Because of this, electric cars have a component known as a charger that takes the AC power flowing into the vehicle and switches it to the more battery-friendly DC. A quicker way to charge up one of these cars is by using a DC fast charger, which provides the car with juice in DC form, so the car doesn’t have to convert it. 

“It bypasses the AC charger [in the car], and goes directly into the battery,” Poon explains. 

[Related: What an electric vehicle’s MPGe rating really means]

So the batteries store power in DC form, but there’s a twist: electric motors work with AC power. This means the vehicle has to transform electricity yet again, which it does using a traction inverter that converts the DC back into AC. “And then that is what actually ends up spinning the electric motor, producing power,” Poon adds.  

There are two key components in an electric motor: a stator and a rotor. The rotor sits inside the stator and rotates using the wonders of magnetism that kick in when AC power hits the motor. 

“We send what we call three phases of alternating current through a stator that has wires that are wound radially, sequentially, around the stator,” he explains. “And we are able to create a rotating magnetic field—so the magnetic field rotates, and it pulls the rotor along with it.” 

And voilá! After passing through some gearing, that rotation turns the wheels on your electric vehicle. 

While an ICE car has one engine, Kirchner, from evpulse.com, notes that electric vehicles in the market can have as many as four motors. For example, the rear-wheel drive version of a Mach-E uses one motor, while the all-wheel drive version uses two—one for the front and one for the back. At the other end of the spectrum, a Rivian R1T can have as many as one motor per wheel.

The pros and cons of driving an electric vehicle

Could you imagine if taking your foot off the gas pedal in an ICE vehicle magically made more gasoline appear in the tank? Something like that happens in an EV.

This cool trick is called regenerative braking, and allows drivers to start slowing down not by pushing the brake pedal as in regular cars, but by taking their foot off the accelerator. Don’t worry—that brake pedal is still there when you need it. In one-pedal or regen mode, things happen in reverse: the wheels turn the motors so they act like generators and send power back to the batteries. 

“You are actually taking the vehicle momentum and putting it back in as chemical energy into the battery,” Poon says.

Mach-E Chief Engineer Donna Dickson says one-pedal driving still remains an unfamiliar technique for drivers, but notes that it helps prevent wear on the brakes while also adding battery charge.

The power source is not the only difference between electric cars and ICE vehicles. There are other details that set the two apart. For example, Kirchner says that while combustion engines have to rev a little to make torque, EV motors make all of their torque from a complete standstill. This results in great acceleration. “Around town, even electric cars that you would not consider sporty by looking at them feel very quick, which makes them excellent city cars,” he continues. 

Another benefit of driving an electric vehicle is that they need less maintenance. There’s no need for an oil change, although their heavier weight means their tires experience more wear and tear. 

On the downside, you can’t charge up the batteries as rapidly or as easily as gasoline goes into a tank, but if you can charge at home, you have a unique perk: “You start every morning with a full tank,” says Kirchner. But that doesn’t always come as easy as it sounds.

“If you are an EV owner, it’s pretty much imperative at this point to have someplace to plug in and charge overnight,” says Paul Waatti, manager of industry analysis for AutoPacific. However, “there’s a good portion of America that doesn’t live in a single-family home.” People residing in condos, apartments, and other residential setups will have a more challenging time finding a charger to plug in their cars overnight. As for public chargers, Waatti says those networks are “very far off from being seamless at this point,” meaning there are too few and many don’t work properly.

To put it very simply: the Rimac Nevera electric hypercar is very, very fast. With 1,194-horsepower, a top speed of 256 MPH, and the ability to accelerate faster than an F1 racer, it’s not just one of the most powerful EVs in the world—it’s one of the most powerful cars, period. The $2.1 million Nevera has dashed past so many world records at this point that its makers are now forced to get creative in setting new ones. And they certainly have, judging from a new video released on November 7.

In addition to all its other feats, the Rimac Nevera is apparently now also the Guinness World Record holder for the “fastest speed in reverse.” How fast did it take to earn yet another laurel? 171.34 MPH—certainly an intense speed in any direction.

[Related: Behind the wheel of the bruisingly quick Rimac Nevera hypercar.]

On Tuesday, Nevera chief program engineer Matija Renić revealed that the new stunt actually began as a joke during the hypercar’s development stage.

“We kind of laughed it off,” Renić said via the company’s announcement. Renić noted its cooling and stability systems, not to mention aerodynamics, simply weren’t engineered for putting the pedal to the floor while in reverse. “But then, we started to talk about how fun it would be to give it a shot.”

Simulations indicated a Nevera likely would top 150 MPH while driven backwards, but there was no way to be sure just how stable it would remain while blazing down the road. “We were entering uncharted territory,” Renić added—an understatement if there ever was one.

But as these multiple videos attest, the Nevera is certainly up to the task should it ever improbably become necessary. According to the company’s record-setting test driver, pulling off the stunt “definitely took some getting used to.”

“You’re facing straight out backwards watching the scenery flash away from you faster and faster, feeling your neck pulled forwards in almost the same sensation you would normally get under heavy braking,” Goran Drndak said via Rimac’s November 7 announcement. “You’re moving the steering wheel so gently, careful not to upset the balance, watching for your course and your braking point out the rear-view mirror, all the while keeping an eye on the speed.” Although being “almost completely unnatural” to the car’s design, Drndak said the Nevera “breezed” through the stress test.

It’s hard to imagine what’s left for the Nevera to achieve, but if the latest record is any indication, chances are Rimac designers will think of something.

In Sweden, the word lagom represents the Goldilocks-esque concept of “not too much, not too little, but just right.” Swedish automaker Volvo had this concept in mind when it created the brand’s newest model, the EX30. At the same time, the electric car had to meet a major objective: have the lowest carbon footprint of any Volvo model to date.

Volvo says that the EX30’s “total carbon footprint” is 25 percent less CO2 than the electrified versions of its C40 and XC40 models, in line with the automaker’s stated goal to cut CO2 emissions per car by 40 percent by 2025. To achieve this, they took into account the manufacturing processes, worked to simplify its design, and reduced the materials it needs. Even the exterior colors like Moss Yellow and Cloud Blue superficially reflect Volvo’s Earth-friendly goals. 

What’s more, the vehicle will cost less than $40,000, which in a world of extra-pricey EVs (the average price for an EV was $53,469 in July of this year, according to Cox Automotive), is impressive. Starting at $36,245 (including destination fees), the EX30 is an attractive package.

Here’s how Volvo achieved its sustainability goals while aiming for that “just right” feel.

Sustainable interior ‘rooms’ 

The company integrated recycled PVC collected from house window frames, PET plastic from single-use water bottles, plant materials like flax fibers, and even discarded denim threads from the blue jeans recycling process into the EX30’s interior. 

Buyers of the new EX30 can choose between four interior expressions for the vehicle. Volvo calls the interior themes “rooms” because people spend so much time in their car, Volvo color and materials designer Camille Audra explained to PopSci

Two interior rooms employ recycling themes: they are called indigo, which is made from denim like the blue jeans you may be wearing right now, and breeze, a patterned knit. And two feature natural materials: they are called mist (flax fiber) and pine (tree resin).

“This is inspired from fashion,” Audra says. “People wear blue jeans everywhere in the world.”

Old denim is often recycled into things like pet bed inserts, building insulation, and thermal packaging insulation.  During the process, Audra says, the short fibers that are left over could become waste, but in this case, are instead collected and woven into a new material.

Combined with cellulose (also a plant-based material) to give strength to the material, the fibers become a durable surface for the dashboard and door panels. Bonus: there are no zippers or button flies to get in the way. 

Along with blue jeans material, flax fiber is lightweight and natural. Also known as linseed, flax is exceedingly strong when woven into fibers. (The flowering plant yields seeds that are pressed to extract oil, or dried and sold as a product in grocery stores around the country. Flaxseed meal—the byproduct of the flaxseed oil-pressing process—has a second life as livestock feed.) Volvo is on track with other automakers, like Kia and Hyundai, that are also using flax fibers inside their cars for sustainability and weight benefits.

“We decided to use flax because it’s used to regenerate soil [between crops] and uses less water than other crops, and still has a nice touch and feel,” Audra says.

In the summer of 2021, Volvo revealed its Concept Recharge, which used flax fibers from a Swiss company called Bcomp. By investing in Bcomp, a company that has also provided products to the racing arm of McLaren or Porsche, Volvo now has a mainline to sustainable materials. 

“Bcomp’s calculations show that compared to regular plastic parts, the natural fiber-based composites are up to 50 percent lighter, use up to 70 percent less plastic and generate up to 62 per cent lower CO2 emissions,” Volvo says

Volvo is also featuring a “room” in a pine theme. The manufacturer uses a material called Nordico, which is made from recycled materials such as PET bottles, corks recycled from the wine industry, and pine resin from sustainable forests in Sweden and Finland.

New colors, natural themes

For one interior trim option, Audra revealed that the design team scanned a piece of granite and then imprinted the granite’s natural patterns onto the recycled plastic. Using a stone grain offers more recycling options later as well, because the texture doesn’t require paint as a finish. 

On the outside, Volvo offers a vibrant hue—probably the brightest color ever seen on a Volvo model—called Moss Yellow, inspired by the lichens that grow on the rocks of the west coast of Sweden. And Cloud Blue looks white in the sunlight but transforms into a soft blue when it’s overcast. 

Even the technology reflects Volvo’s all-in commitment to a low carbon footprint. By keeping parts to a minimum, Volvo creates fewer carbon emissions when manufacturing the EX30. So far, its strategy is working: the brand expects 80 percent of EX30 buyers to be new to Volvo, and overall sales are skyrocketing. 

Correction on Nov. 8, 2023: This post has been updated to clarify that the denim material is used on the dashboard and door panels, not the seats.

How smart trailers could give trucking a clean, electrified boost https://www.popsci.com/technology/range-energy-electric-trailer/ Sat, 04 Nov 2023 11:00:00 +0000 https://www.popsci.com/?p=585958

A special trailer from Range Energy aims to follow the truck tractor "like an obedient dog." Here's how it all works.

The post How smart trailers could give trucking a clean, electrified boost appeared first on Popular Science.

One of the most ubiquitous sights on the road is an 18-wheel truck. These large, loud vehicles are a prolific presence on America’s interstates, and are made up of two big components: the tractor, which does the pulling and is where the driver is, and the trailer, where the stuff goes. 

In an effort to clean up the relatively large emissions that come from this part of the transportation sector, some companies are working on electric tractors that can pull trailers: Freightliner has a model called the eCascadia, Tesla has its Semi, Volvo its VNR, and others are working on it, too. But a relatively new company called Range Energy is focusing on the trailer itself, equipping it with batteries, a motor, and other intelligence. The trailer can be paired with a tractor burning diesel, or an electric one, like one of those eCascadias. 

Currently, there are about 3.5 million trailers in the United States, according to a company called ACT Research.

Range Energy is led by Ali Javidan, an early Tesla employee and veteran of Google and Zoox, the autonomous car company now owned by Amazon. Javidan also brings something else to the table: experience towing things. “I’ve always been around equipment, cars, trucks, stuff like that,” he says. “A few of my uncles had car dealerships, mechanic shops, lots of land in Sacramento. And so growing up, one of my first experiences driving was towing cars from the dealership to the service center, or moving boats around the farm, or things like that.” 

So while he points out that he has “very, very limited time in a class-8 tractor trailer,” which is a big 18-wheeler, he adds that he has “lots of towing empathy.” 

[Related: Futuristic aircraft and robotic loaders dazzled at a Dallas tech summit]

Range’s RA-01 product looks like a regular trailer—typically a big, boxy, and boring presence on the road—but has some key changes. There’s a motor that turns one of the axles at the back of the trailer. That motor gets the power it needs from an onboard battery pack, which isn’t inside the trailer (where it would interfere with cargo space) but is below it. There’s also what Javidan refers to as “smart kingpin.” A kingpin on a big 18-wheel truck is the point where the trailer connects to the tractor. What makes the Range Energy kingpin different from a regular kingpin is that it senses what the tractor is doing. “It’s a real-time measurement of how hard the tractor is pulling,” Javidan says.

Because it gathers this information, the trailer can be “kind of like an obedient dog on a leash,” he says, with the goal of making the trailer feel “essentially weightless” for the tractor. The trailer wouldn’t ever push the tractor, though. 

The result, according to Range, is that if this trailer is paired with a diesel-burning tractor, that tractor could get around 35 to 40 percent better fuel efficiency. And if it were paired with an electric tractor, it could add about 100 miles of range or more. 

Another benefit potentially arises from what happens when a truck towing a Range trailer goes downhill. That’s because of regenerative braking, which uses the motion from the wheels to charge the battery back up and simultaneously slow the whole rig down. That means that the truck’s brakes get less wear and tear, too. “The second-biggest maintenance item on a trailer is brakes,” he says. (Tires take the top slot.) Plus, Javidan says that the system has a stability boost going downhill, “because we’re dragging from the trailer.” 

The most obvious negative tradeoff that comes with electrifying the trailer is weight. “It adds about 4,000 pounds to the total system,” Javidan says. (A tractor-trailer rig has to stay below 80,000 pounds in total, although an electric tractor gets an additional 2,000 pound allowance.) For trucks hauling something heavy, like soda, this could affect the amount of goods they can transport in one load. But many trucks carrying stuff have “cubed out,” Javidan says—meaning that the truck’s interior space fills up before hitting the maximum weight limit. (Just think about an Amazon box filled packaging around something small, like toothpaste, and you get the idea.) 

Javidan says that they’ll start beta testing next year, with deliveries to customers planned for 2025. “You will start seeing these trailers on the roads in real volumes starting in 2026,” he predicts. 

There’s good reason for regulators and companies to work on cleaning up this transportation sector, both from a climate-change perspective and a public-health one. If you consider buses and medium- and heavy-duty trucks, those big rigs make up just 6 percent of vehicles on the roads in the US, but account for sizable portions of greenhouse gas emissions and nitrogen oxides (NOx). In other words, they are “disproportionately emitting emissions,” says Stephanie Ly, the senior manager of eMobility Strategy and Manufacturing Engagement at the World Resources Institute. 

The NOx emissions have “major public health impacts,” she says. Exposure to this diesel-heavy industry has serious ramifications for people, with repercussions like “years of life lost” as well as “asthma, cancer, infertility, and so many other negative effects, particularly for those that live nearest to high-traffic truck centers,” she says. And these groups, Ly adds, “are primarily communities of color, and communities that are lower income, or have less access to different types of employment, so they’re especially vulnerable.”

With Range Energy’s plan to electrify the trailer, Ly notes that “it’s absolutely fascinating what they are proposing.” That said, just as there are multiple companies working on creating electric tractors that do the pulling, other firms also are working on electrifying the trailer, too. ConMet eMobility, ZF, and Einride all represent potential competitors for Range. 

“I will say in the trucking sector, there’s quite a bit of brand loyalty within the supply chain,” Ly adds. In other words, any new player might have something of a long haul ahead of them as they try to pull onto the highway, get into the right gear, and travel down that open road.

A new blue paint color for cars uses nano-pigments to boost its intensity https://www.popsci.com/technology/car-color-science/ Mon, 30 Oct 2023 19:00:00 +0000 https://www.popsci.com/?p=584375

Way more goes into picking a vehicle's paint color than you might imagine.

The most popular car paint color in America is white. The hue has names like Blizzard White, Snow Quartz, and Wind Chill Pearl. Black, gray, and silver aren’t far behind on the popularity scale, rounding out the vast majority of cars on the road. 

These stats don’t mean that automakers are staying monochrome, though. On the contrary, Italian automaker Fiat thumbed its nose at bland colors and declared earlier this year it wouldn’t make cars in any shade of gray. Jeep likes to debut names for its vehicle finishes that are as colorful as the paint itself: Snazzberry, Hellayella, and Punk’N, for example. And Mazda has established itself as a colorful brand with its ubiquitous Soul Red Crystal Metallic and new Artisan Red, which morphs from a black cherry look in the sunlight to a dark, almost-black tint on a cloudy day or at dawn and dusk. 

Automakers use electrostatic spray guns to apply even layers of paint on the vehicles they produce, and car paint has evolved into a high-tech science that delivers more colors than designers imagined even 10 years ago. 

For example, Honda’s luxury arm, Acura, debuted its new Precision EV concept last year; it sports an arresting blue finish that seems to radiate from the inside out. Gypsy Modina, who leads the brand’s color and materials group, created the Double Apex Blue Pearl tint, which will grace the 2024 ZDX Type S. 

This is how Modina whips up pigments that set Acura apart and how she sees the future of paint and color technology.

Color inspiration 

Modina got her degree in fine arts at the College for Creative Studies in Detroit, the alma mater of notable automotive designers like Ralph Gilles, chief design officer for Stellantis, and John Krsteski, senior chief designer for Genesis. She started working for Acura 18 years ago, and now mixes colors like a mad scientist for the brand to come up with bespoke paint finishes. 

Her job seems more science than art. She has to understand how light bounces from the vehicle to the eye and how the color accentuates the form and fits the personality and demographic of that car. 

“I don’t think I knew I’d be doing so much science and math [in this field],” Modina says wryly. “It’s funny, because I find it hard to follow a recipe when cooking.” 

She doesn’t sit at her desk dreaming up color combinations. Instead, the process is more exciting: Modina travels the world seeking inspiration and finds it in fashion-forward places like Milan, Italy but also in nature, hiking in locations as far-flung as Kruger National Park in South Africa.

What Modina sees coming down the pipeline is colors and materials that are designed with the goal of minimizing waste and pollution by recycling, and using more natural versus chemical materials. Interestingly, that doesn’t align with what some manufacturers are showing off on the technology side, like the BMW SUV that features a specially developed body wrap stimulated by electrical signals to change color.

“Now you’re seeing concepts that change colors and car bodies that are more like screens,” Modina says. “There are things you can create that can be more solutions to a circular economy. The goal is for circularity, and I do think optimistically that there are material technologies and sciences that can [contribute to that].” 

The topic has a colorful history: Back when cars used to be spray-painted by hand with layers upon layers of pigment, the overspray would build up in the paint bays. Over time, chunks of buildup needed to be removed, and someone along the way discovered the beauty of baked-on layers of color that could be polished into gemlike stones. You’ll find “Fordite” stones (also called “motor agate” or “Detroit agate”) as pieces of jewelry on Etsy and other sites. But the process that created these multicolored polished stones no longer exists.

Car paint that glows even when it’s cloudy

On a cloudy and gray day during Monterey Car Week in August 2022, Acura unveiled its Precision EV in Double Apex Blue. That kind of weather could be an unfortunate backdrop for the high-profile presentation of a new car, but the blue finish looked like it was glowing even through the gloom. Modina and the design team breathed a sigh of relief. 

“We were giving each other high fives,” Modina says. “There aren’t that many colors that do that.”

The glow is a physical manifestation of what Acura’s first all-electric vehicle, scheduled for delivery next summer, represents. 

Modina leads the brand’s color and materials group.

“We knew electrification was coming into play and we wanted the blue to go more liquid and more sheer,” Modina says. “There’s something about electrification that has a smoothness to it and we wanted [the paint to appear] more liquid. We also wanted it to be unique; we saw in the US market that people are more open to bold colors.”

The form language (the term refers to design styles unique to each manufacturer) and shape are closely related to the brand, Modina says. She and her team design many different types of hues, but the brand’s Double Apex Blue and Performance Red stand out because they must lay on the body in a way that matches the brand’s personality. Blue, in particular, is a heritage color for Acura, and has been refreshed over the years. This particular blue includes nano-pigments, which are finer particles that load the color with higher saturation, making the tint appear more intense. 

Light, color, and form work together with our emotions to stimulate a response; in Acura’s case, the brand wants us to see its cars as fast and performance-oriented. Even if they’re popular, cars in bland colors just can’t measure up.

Hundreds of years before Google Maps and other apps like it made navigation as easy as looking at your smartphone, explorers found their way around the planet by the light of the moon and stars, or by shadows cast by the sun. Today, humans rely on electronic devices, not their instincts or the study of celestial bodies. And of course before the smartphone came along, people also used maps printed on dead trees. But kids born recently aren’t using paper maps at all; instead they just punch in an address to receive a route to get where they’re going.

Off-roading champion Emily Miller wanted to teach others what she learned from years of navigating with a ruler, pencil, compass, and topographical map. With that in mind, she created the Rebelle Rally, the longest off-road time-distance navigational rally in the United States. The idea of a navigational rally might not be novel, but this one is: All competitors are required to disable any digital navigational aids on their vehicle and seal up their electronic devices (mobile phones, AirTags, tablets, laptops, and more) for the duration. It’s a test of driving precision and navigation skills, not a speed race pell-mell across the desert. 

Over eight days, Rebelle Rally competitors are shut off from the world, sleeping in tents near ghost towns and rock faces instead of hotels and cities. This year, the rally’s course started in Mammoth Lakes, California, crossed into Nevada, and finished in the southeast corner of California at the majestic Glamis Dunes. The only news participants hear is their daily standings in the competition—there’s no endless scrolling of social media feeds. Plotting latitude and longitude points requires one’s full attention, and by the end of a 10-hour day spent hunting checkpoints, there’s no need for entertainment. The competitors are wiped out physically and mentally, heading for their tents to sleep.

I just completed my second year of the rally; I was sponsored by Hyundai and we operated a Santa Cruz with a 1.5-inch lift in the front and a 1-inch lift in the back. We had off-road accessories (traction boards, shovels, and a spare tire) mounted to a custom Rally Innovations rack to help us along. This is what it’s like to compete at this crossroads of analog and high-tech.

Analog navigation

Now entering its ninth year, the Rebelle Rally just wrapped up its most recent competition with 65 teams of two women each; the all-female event concluded on October 20. Each morning, the teams were alerted that it’s time to get going by the gentle clanging sound of a cowbell at 5 a.m. Many teams are already up by that point, the sounds of tent zippers tearing the fabric of the silence even before that.

Each day, a race official distributes a list of 20 or more checkpoints to the teams long before dawn. Then teams plot latitude and longitude points along with distances and headings on their paper maps. On-the-ground checkpoints are marked with flags (mandatory green checkpoints, the easiest), or poles (blue checkpoints, which are more difficult to find) or invisible geofenced areas (black checkpoints, requiring precision within 200-300 meters to avoid a penalty). 

Once a team drives to the checkpoint and sees the flag, or sees what they believe to be the spot, one of the competitors clicks on a satellite tracker that displays the exact latitude and longitude point where the signal is traced. A company called YB Tracking and the Iridium satellite network track the competitors to keep them safe; the staff knows exactly where each car is, even if the teams themselves are lost. 

Teams also participate in enduro segments, which are a series of checkpoints that include time checks along the route and require intense focus and concentration to stay at the average dictated speed, which may change frequently. To prepare for these on-time sections, competitors use mathematical formulas to calculate the seconds and minutes of each segment in the precise roadbook based on the distance and speed. 

Using a solar-powered calculator and a basic stopwatch, we found our way.

Green power takes the gold

After seven days of full-time driving plus the half-day prologue, it was a team called the Limestone Legends that took first place in a Rivian R1T all-electric pickup truck. Not only was it the first time an all-electric vehicle earned the gold medal in the Rebelle Rally, the second place vehicle was a hybrid: a Jeep Wrangler 4xe. Rivian has been a strong supporter of the Rebelle Rally starting in October 2020 with a pre-production model of an R1T, which became the first fully electric truck to ever compete in the event. 

Charging up an EV in the middle of the desert is a challenge. While gas-powered cars are fueled up by a tanker that travels from base camp to base camp with the rally, it’s not as easy to provide a boost for batteries that way. So, the Rebelle Rally partnered with Renewable Innovations to provide hydrogen-powered EV charging to the Rivian and Jeep 4xe models each day. 

Each base camp embraced green energy too, mobilizing a 53-foot mobile Renewable Innovations semi with high-density solar panels combined with “follow-the-sun” smart flowers on each side to collectively deliver 50 kilowatts of peak power for base camp. 

While our phones and navigation systems were unavailable by design, my team did have a Nextbase dash cam in the car so we could capture the beauty of the off-road trails in California and Nevada. It came in handy when we witnessed a crash—a Mitsubishi crossover tried to pass us and the full-size SUV in front of us on the left. We handed over our camera’s memory card to the police, providing an airtight record of what happened. And luckily, no one was seriously hurt.

“I always build things,” says Dan Hryhorcoff. 

Case in point: Hryhorcoff has constructed an absolutely delightful giant bumper car, a project that he says began during the pandemic. The rest of us may have baked bread as COVID came down the pike, but Hryhorcoff, who lives in northeastern Pennsylvania and has also built a submarine, constructed an enormous blue bumper car. It gets its propulsion from a repurposed Chevrolet engine and is street-legal. 

Before he constructed the big bumper car, Hryhorcoff had made a different vehicle, starting on it around 2013 or so. “When I retired, I decided I kind of wanted to build a car,” he recalls. For that project, he chose to focus on a 1950s pedal car for children called a Murray “sad face.” “I decided to copy that and make a large one.” (Those Murray models have a front that does indeed look like a sad face, but anyone who sees Hryhorcoff’s work will probably smile.) 

Creating that big red vehicle provided him with further experience working with fiberglass, a material he had also worked with when building the submarine. “I had a lot of fun with that [Murray car] at car shows and things, and it got a lot of attention from a broad audience,” he says.

“Then COVID hit,” he adds. He wanted a new project. His thinking? “Another car project would be good.” 

Building the big bumper car

He settled on a bumper car. To get the source material he needed for the project, he turned to an amusement park in Elysburg, Pennsylvania called Knoebels, and the bumper cars they have there. Specifically, he focused on the 1953-model bumper car that was made by a company called Lusse. He liked that it had a “Chevrolet pickup truck sorta look” from the 1950s. 

“I decided to copy one of those,” he says. Spending some eight hours at Knoebels gave him the chance to get the information he needed. “I measured, and took photos, and made templates, and whatever I needed to, to copy the car as well as I can.” He chose to make his version of the car double the size of the base model. As the Scranton Times-Tribune noted in a story about Hryhorcoff in July, the bumper car ride at Knoebels dates back to the immediate post-World-War-II era.

Inside, the big bumper car’s power plant comes from a Chevrolet Aveo. “I took the front of the Aveo, and chopped it off, and put that in the back of the bumper car,” he explains. “And the front of the bumper car is a motorcycle wheel.” That single wheel up front means it can turn very sharply. The exterior is made out of fiberglass. All told, it measures 13 feet long, 7 feet wide, and 5.5 feet tall, making it twice the size of a regular bumper car. A pole in the back mimics the way actual bumper cars get their electricity, except this one connects to nothing. 

A project like this would likely be a bumpy ride for anyone without the experience that Hryhorcoff, 72, brings to the table. “I learned to run a lathe when I was 13 years old, with my dad, and he was kind of a jack-of-all-trades,” he recalls. (A lathe is a tool for forming metal into a round shape, and a wood lathe is the kind of equipment you could use to make a baseball bat.) He built a go-cart, tinkered with lawn mowers, and learned about auto repair in a garage. His interest, as he describes it, was “all around mechanical.” 

He spent four years after high school in the Navy in the early 1970s, where he worked stateside and repaired radios for F-4 jets, and then studied mechanical engineering at Penn State. After working for a drilling company, he started his own machine shop called Justus Machine.

Always diving into something new

The submarine he built came from plans for a K350 model purchased from George Kittredge, and is called Persistence. “I knew I was building something that wasn’t gonna kill me, if I build it correctly,” he says. (Watch a video of the sub in action here.) That sub has gone as deep as 540 feet with no one on board, Hryhorcoff says, and he’s taken it down himself to about 150 feet deep.

Hryhorcoff describes himself as an engineer, not an artist, and prefers to follow plans and undertake projects in which he knows any challenges he might face are surmountable. “Any project I’ve ever chose was a project that I knew I can get through it, but I had something new to learn in the process,” he says. “There were always some unknowns.” But those unknowns, he adds, were within the realm of doable for him and his equipment, even if he had to learn new stuff along the way.

“I’d rather big projects, rather than a dozen little ones,” he adds.

The Cybertruck is set to finally arrive after a nearly two-year delay. Tesla

First officially unveiled back in 2019, Tesla’s electric Cybertruck impressed and amused the public with its angular, “Blade Runner-inspired” design and purported features including reinforced glass, stainless steel body, and a lack of door handles. Although originally slated to arrive in reservation holders’ driveways in 2021, the EV release faced numerous delays exacerbated by COVID-19 pandemic supply chain issues. This week, however, Elon Musk said Tesla’s long-delayed Cybertruck will finally roll off the company’s Giga Texas lot on November 30, when Tesla is now scheduled to begin delivery. However, the company’s CEO cautioned investors against early celebrations.

During the company’s Q3 earnings call on October 18, Musk stressed that both customers and shareholders should “temper expectations,” particularly for the Cybertruck’s initial profitability. Tesla faced various challenges with scaling and ramping up production. Musk went as far as to say, “we dug our own grave with Cybertruck” during the vehicle’s multi-year hype campaign.

[Related: Tesla’s Cybertruck is the latest lofty promise in the world of electric pickups.]

“Cybertruck is one of those special products that comes along only once in a long while. And special products that come along once in a long while are just incredibly difficult to bring to market to reach volume, to be prosperous,” Musk opined, as reported by The Verge on Wednesday.

The Cybertruck base model was initially estimated at $39,900 in 2019, but Tesla is expected to announce updated pricings during its November 30 release event. No price ranges are currently available on Tesla’s website, but customers can still put down a refundable $100 deposit for a Cybertruck with the promise to “complete your configuration as production nears.”

In the meantime, multiple companies have released their own electric truck options, including the Ford F-150 Lightning and Rivian’s R1T. During this week’s Tesla earnings call, the company stated that it had the capacity to produce more than 125,000 Cybertrucks annually. Musk said he saw a potential for Tesla to produce 250,000 Cybertrucks in 2025. Musk said that more than one million people have reserved the Cybertruck so far.

[Related: Here is what a Tesla Cybertruck cop car could look like.]

The product may not be ready, but the concept keeps iterating itself. In September, Oracle co-founder Larry Ellison teased concept art for a Cybertruck cop car including EV’s recognizable design beneath red and blue emergency lights, a bull bar, and multiple Oracle logos. “Our next generation police car is coming out very soon,” Ellison, a “close friend” of Musk, said during his presentation at the data service giant’s CloudWork conference to audible murmurs in the crowd. “It’s my favorite police car. It’s my favorite car, actually. It’s Elon’s favorite car.”

Musk’s desire to release an electric pickup truck dates as far back as 2012, when he tweeted he “would love make a Tesla supertruck with crazy torque, dynamic air suspension and corners [sic] like its on rails.”

“That’d be sweet…,” he added at the time.

These large chains offer maximum durability to support the weight of heavy-duty pickup trucks.

When driving on snowy and icy roads, often the one thing that can keep you from getting stuck is a good set of tire chains. These vehicle accessories consist of metal chains that install around the wheels of your vehicle to maximize traction in snowy and icy conditions, making them a necessity for those who live in regions that see extreme winter weather each year. In fact, some states even require snow chains if traveling in certain mountainous areas during extreme winter weather. Finding the right set can be challenging, as not all tire chains are identical. They come in different sizes, materials, and tread patterns to suit different types of vehicles and varying severities of winter weather. Many models are designed to be easy to install, reducing the time one has to spend out in the cold. Learn what features are vital to consider when shopping for these winter weather vehicle accessories and find out why the models below are some of the best tire chains on the market.

How we chose the best tire chains

In reviewing more than 25 sets of tire chains for this article, we considered what sets best suit vehicles ranging from smaller cars to large SUVs and heavy pickup trucks, keeping the following considerations in mind:

Traction: Although traction isn’t the only thing, it’s clearly the most important factor in tire chains. We chose only models that provided ample traction.

Durability: I only included chains made from steel alloys that could hold up to supporting the weight of a vehicle in difficult weather conditions. This included traditional tire chains and those that use steel rollers or coils.

Installation: Tire chains are typically installed in extreme winter weather on the side of a road or in a snow-covered driveway. With this in mind, we only chose tire chains that one could capably install in these conditions. Tire chains with self-tightening features outranked those that required manual tightening.

The best tire chains: Reviews & Recommendations

Whatever kind of vehicle you drive, you don’t want to go out in the winter without the best tire chains, because even the best heated gloves, socks, and vests (even a battery-powered electric blanket) don’t keep you as comfortable as getting home and out of the storm safely. We’ve rounded up the best options on the market. from heavy-duty to budget-friendly picks.

Best overall: Peerless Auto-Trac Light Truck/SUV Tire Traction Chain

Peerless Auto Trac

SEE IT

Why they made the cut: This pick eliminates the major headache with tire chains—putting them on—with an innovative design that essentially automates the installation process, making them one of the most user-friendly options on the market.

Specs

  • Material: Manganese alloy chain
  • Shape: Diamond
  • Size options: 14 to 20 inches

Pros

  • Easy to install
  • Excellent traction with a diamond-shaped pattern
  • Durable steel alloy construction

Cons

  • A little on the heavy side

Tire chains generally aren’t user-friendly. Most require you to jack the car up to properly tighten them to the wheel, which often involves paying someone else to do the work. That’s not the case with Auto-Trac’s Peerless tire chains, which use a tensioning system that automatically tightens the chains to the wheel. To install, simply attach the internal cable to the tighteners that run around the outside sidewall of the tire and begin driving to activate the ratcheting system that tightens the chains.

The diamond pattern of this set of chains not only facilitates the automatic ratcheting system, creating a tight grip around the tires, but it also makes for better performance by creating more surface area and improving traction.

In addition to being easy to install, this set is durable, thanks to its manganese steel alloy construction and heavier gauge chain links. Of course, that gauge also makes these chains on the heavy side at 15 pounds for the set. With sizes ranging from 14 to 20 inches, this set of chains is one of the more versatile options on the market, capable of fitting light trucks, SUVs, and cars.

Best heavy-duty: AutoChoice 6 Packs Car Snow Chains

AutoChoice

SEE IT

Why they made the cut: The thickness and coverage of these chains take the traction one can get from a set of tire chains to another level. And while the installation may take longer, it’s less complicated.

Specs

  • Material: Steel
  • Shape: Squares
  • Size options: 14 to 20 inches

Pros

  • Heavy-gauge chains provide optimal traction
  • Separate pieces make them easier to install
  • Fits a wide variety of tire sizes

Cons

  • Installation is more time-consuming
  • Expensive

One look at this set of tire chains from AutoChoice, and one can see that they are much beefier than other models, thanks to sets of six thick chains for each tire. With their thicker gauge and square design, these chains dig into snow and ice to provide ample traction. The chains are divided into six separate pieces per wheel—a six-pack—which attach independently. The chains have thick straps that consist of tendon material that thread through the rims and tighten to the wheel in a similar fashion to ratcheting tie-down straps.

This design has both positives and negatives. By having separate pieces, they’re easier to install, as there is no need to untangle and line up a single stretch of chain or jack up the wheel. Simply apply one set, then move on to the rest. On the flip side, attaching six separate sets of chains to each wheel is time-consuming.

While this set of tire chains is on the pricier side—you’ll need to buy a set of six per wheel—it does include some useful extras, including two pairs of gloves, a long hook to help with mounting, and a fiber-absorbent towel.

Best low-profile: Glacier Passenger Cable Tire Chain

Glacier

SEE IT


Why they made the cut: Although there is a trade-off in traction, we love the low-profile design of this set of chains, which makes them suitable for most cars.

Specs

  • Material: Steel rollers
  • Shape: Square
  • Size options: 14 to 20 inches

Pros

  • Fits type S low-profile vehicles
  • Lighter weight makes them easier to install
  • Affordably priced

Cons

  • Traction isn’t as good as standard tire chains

Tire chains can be tricky with passenger vehicles with S clearance, which means there is limited space between the wheel well and the tire. Adding the additional thickness of snow chains can damage the car as the chains scrape against the wheel well when the suspension flexes. In fact, some car manufacturers will even void warranties if they find that a car has used chains that are too bulky for the wheel well.

Glacier solves that problem by creating tire chains that aren’t really chains at all. Glacier’s tire chains actually consist of a set of hardened steel rollers that run perpendicular to the tire treads and secure to a thick gauge wire cable that runs the circumference of the tire’s outer sidewall.

The result is a tire chain with a low enough profile that it can fit S-clearance passenger vehicles. And, at 6 pounds, these chains are also easier to install than heavier sets. Keep in mind that there is a trade-off. While these roller-style chains will improve vehicle traction for snowy weather, they don’t provide the same traction as a set of traditional tire chains.

Best for trucks: Security Chain Company Quik Grip

Security Chain

SEE IT


Why they made the cut: Though they may be tougher to install, you can’t argue with the fact that these chains offer the superior traction and durability that heavy-duty trucks driving on snow-covered roads require.

Specs

  • Material: Alloy steel chain
  • Shape: Square
  • Size options: 15-20 inch

Pros

  • Durable all-chain construction
  • CAM tightening system makes installation easier
  • Thicker gauge chains provide superior traction

Cons

  • Harder to install than other types
  • Won’t work with low-clearance vehicles

Larger trucks and SUVs require heavy chains that won’t break under intense weight or extreme conditions. Thanks to their durability, these thicker steel alloy manganese chains are one of the best options for full-size trucks. They’re even rated to work with farm equipment and dual-wheeled trucks.

Security Chains’ tire chains have a square configuration design, which provides maximum start-up traction. We like this set in particular because of the integrated CAM tightening system that eliminates the need to use tensioners to tighten the chains. The Quik Grip chains that don’t have this feature are less expensive, but we think it’s worth the additional cost to save the hassle of purchasing tensioners separately.

Even with the CAM tightening system, these chains are more difficult to install than other options, but the superior durability and traction they offer make them a must-have for heavy-duty trucks that face severe winter weather. Remember that these chains won’t fit trucks with S-class clearance requirements.

Best budget: Security Chain Company Super Z6 Cable Tire Chain

Security Chain

SEE IT

Why they made the cut: These tire chains are inexpensive and versatile, capable of fitting most cars, trucks, and SUVs. We also like the design, which makes them easier to install than other tire chains by eliminating the need for manual tightening.

Specs

  • Material: Alloy steel coils
  • Shape: Diagonal
  • Size options: 14 to 20 inches

Pros

  • No need to manually tighten
  • Low profile makes them compatible with most vehicles
  • Affordably priced

Cons

  • Steel coils do not provide as much traction

This versatile set of tire chains from Security Chain is easy to install, affordably priced, and will fit vehicles with restricted clearance around the wheels. They consist of alloy steel traction coils thinner than standard chains, making them compatible with most cars. They only require a quarter-inch of sidewall clearance, so they’re suitable for most cars and SUVs as well as trucks.

These tire chains are also easier to install than other models thanks to rubber connectors that hold the coils taught, eliminating the need to tighten the chains manually.

This set of chains also preserves handling better than bulkier chains while preserving such important safety features as anti-lock brakes, traction control, and all-wheel drive. Keep in mind there is a trade-off. The low profile and limited coverage of the coils do provide less traction than larger sets of tire chains.

Things to consider before buying tire chains

Traction

Perhaps the most important trait to consider is how well the chains will keep you from getting stuck. The rule of thumb is rather straightforward when it comes to traction. The thicker the chain and the more coverage on the tire tread, the better the traction. Chains with heavier gauge steel links will dig into snow better than coils or rollers, providing better traction. Keep shape in mind as well: Square-shaped chains may provide better traction for getting started but diamond-shaped chains provide better directional traction, which means better handling.

Material

Please pay attention to what the chains are made from, which will determine their durability. Generally speaking, a steel alloy with manganese is considered “high strength” steel, which can better withstand the pressures exerted on it when functioning as a tire chain. While chains may have superior strength, steel alloy rollers and coils are also quite strong. In addition to the chains, pay attention to other materials they use to hold them in place. While rubber and thick nylon straps may be durable enough for cars and light trucks, heavy-duty trucks require all-chain construction.

Size

Size is important because the tires must be compatible with the size of the tires on your vehicle. Tire chains are not one size fits all. Most models of tire chains come in a broad range of sizes to suit different tire sizes. Tire chain manufacturers include size charts that correspond to the model numbers of their products. Check the size of your tires (printed on the sidewall of each tire) and match that size to the right model tire chain.

Installation

Most likely, you’ll be installing tire chains in inclement weather, so it’s important to purchase chains that you can install as quickly as possible. If you have a car or small truck, consider purchasing a set of tire chains that are self-tensioning. Self-tensioning chains take a little more work to install initially, but they don’t require you to tighten (and retighten) the chains manually.

FAQs

Q: Do you need tire chains for all four tires?

Legally, you only need to have one set of tire chains to travel in mountainous areas during the wintertime. However, if you have a 4×4 vehicle, it’s a good idea to have two sets. Even with a two-wheel-drive vehicle, two sets of chains can improve traction.

Q: Do chains damage tires?

When there is ice and snow, tire chains dig into them and don’t put pressure on your tires. However, driving on bare roads for long stretches can cause the chains to dig into your tires and damage them (as well as the road itself). Chains can also damage tires if they are not properly installed.

Q: Is it hard to drive with snow chains?

Although snow chains will improve traction and help prevent your car or truck from getting stuck, it is still hazardous to drive in snowy conditions. When driving with snow chains, you should never exceed 30 miles per hour.

Final thoughts on the best tire chains

Choosing the right tire chains requires finding a product balancing good traction and easy installation. The Peerless Auto-Trac Light Truck/SUV Tire Traction Chain excels on both fronts, making it one of the best all-around tire chains you can put on your car or truck. If you’re looking for a set of chains to outfit your heavy-duty pick-up truck, then consider going with Security Chain Company Quik Grip, which offers superior traction and durability.

Your ride is definitely not the private sanctuary you think it is.

You are more than a data point. The Opt Out is here to help you take your privacy back.

AMERICANS SPEND A LOT of time in cars. Whether you have a long commute, enjoy riding with friends as they drive around, or just like sitting in the parking lot for a bit of solo time, a car might feel like an extension of your home—an intimate space for you to sing out of tune or seek silence in the middle of your day.

Unfortunately, if you’re in a car that was manufactured within the past few years, that environment isn’t as private as you think it is. Carmakers have been adding sensors, cameras, and microphones to their vehicles to improve safety and usability, but these bits of tech are also collecting a hefty amount of data that the automotive industry and other companies are selling and sharing. And don’t think this applies only to car owners: Your privacy is also at risk if you rent a car or are simply sitting in a passenger seat.  

These newer cars know what you say, where you go, and possibly even whom you’re sleeping with and how often. It’s scary, but what’s scarier is that consumers currently have little choice but to consent. 

More than computers on wheels

Cars have been equipped with onboard computers and sensors for a while now. The tools’ applications have always been rather practical—letting you know when your fuel tank is close to empty or when your machine is due for an oil change, even allowing you to get full system diagnostics via Bluetooth. But as technology advanced, so did the role of electronics within every vehicle. Now cars can help you master parallel parking, respond to your voice commands, and even alert you to the presence of other drivers as you change lanes.

“A lot of this can be used as safety features, but [car companies] are not going to let the opportunity to collect data and make money off of that slip away. They’re not just doing it for safety,” says Jen Caltrider, program director for Privacy Not Included, a series of privacy-focused consumer product reviews, at the Mozilla Foundation. 

The same navigational tool that guides you to your destination, for example, is collecting your location data, and the sensors that show which passenger hasn’t buckled up can tell if you’re alone or not, where people are sitting, and if there’s any movement. Those capabilities alone provide hundreds, if not thousands of data points every day that go straight to the car manufacturer’s servers. It’s hard to tell if any of that information is encrypted or not, Caltrider says.

Other than what your car’s sensors and cameras track, manufacturers also learn about you from other sources. If you’re buying a car, the data harvesting starts with every visit to the dealership or the brand’s website, and it continues when you enlist the help of a bank or some other type of financial institution to pay for your car. Then, when you drive home in your new ride, manufacturers keep gathering data through the car’s app. You can choose not to use the app, but it’s likely you’ll lose access to any vehicle features that require it, such as remote ignition. And then there’s what Caltrider and her team call “connected services,” including insurance companies and navigation and entertainment apps like Here and Sirius XM, which have basically become data brokers in the vehicle data industry. The bad news is that it’s unclear exactly how the information flows, how it’s shared, and where and how it’s stored. 

Your car might know too much about you

In September, Caltrider and her research team at the Mozilla Foundation launched an in-depth analysis of the privacy policies of 25 car companies doing business in the US, including the most popular ones: Toyota, Ford, Chevrolet, and Honda. The results? The Mozilla team labeled cars the worst product category it has ever reviewed for privacy.

When you read the privacy policy for any app or device, it’s common to feel confused. Tech companies have been writing privacy policies for decades, and they generally include broad or vague terms that make you feel as if they care about your data—or at least don’t make it obvious that they don’t. Car privacy policies are different: way more explicit and entirely absurd.

“Car companies are moving into the tech company world,” Caltrider says. “But they’re so inexperienced at it and it really shows.”

One of the wildest privacy policies in the Mozilla Foundation’s report is Nissan’s, which requires users to consent to the collection of sensitive information including sexual orientation, sexual activity, health diagnosis data, and genetic information. The document also says this data can be sold or disclosed to third parties for targeted advertising. It’s not clear how exactly Nissan is collecting this data or if it’s currently capable of doing so, but the fact that you’re agreeing to all of this by simply buying a Nissan is problematic enough. 

And these requirements don’t affect only drivers and car owners, as consent is murky territory in the land of vehicle privacy policies. For one thing, cars don’t grant the same control over data collection that your phone does. Most of the time, car owners will see a request for permissions on a single screen that pops up when they first set up their new car, and they may not be able to go back to it and revoke those permissions later on. 

That also means there’s assumed consent from anybody who steps inside the vehicle. Privacy policies like that of Subaru make it clear that terms and conditions affect everyone on board, regardless of whether they’re the vehicle’s registered owner or not. This means that the company burdens Subaru owners with the responsibility of informing all their passengers about the privacy policy and assumes that people are agreeing to it just by stepping into the car. It’s a safe bet that no ride-share driver or courteous coworker has ever read you a long list of types of data collection you needed to consent to before they’d give you a ride home. 

Car manufacturers, vehicle data hubs, and other actors in the industry, like insurance companies, calm concerned drivers and passengers by promising that the data they collect and save is anonymized, meaning it cannot be traced back to specific people. While anonymizing data is a common practice that’s meant to protect individuals’ privacy, research has shown that it’s not always effective and that the owner of any anonymized data can be easily re-identified when the information is combined with other datasets. This is especially true when location data is involved, Caltrider says. 

As we’ve mentioned, targeted advertising is one of the main uses car companies and third parties have for collecting data with vehicles, but it’s not the only one. More than half of the manufacturers analyzed in the Mozilla Foundation’s report say they can “share your information with the government or law enforcement in response to a ‘request.’” This leaves a lot of room for abuse, as there are no details about whether this request can be as informal as a call or an email to the right person, or if it must be a powerful document, like a court order. 

Unlike with home security cameras, it’s hard to tell exactly how many times these companies have responded to requests from police and other law enforcement agencies. But a 2021 Forbes investigation revealed that both Customs and Border Protection (CBP) and Immigrations and Customs Enforcement (ICE) had been requesting information from three companies in the vehicle data industry, including General Motors, which is the parent company of Buick, Chevrolet, Cadillac, and GMC. 

Regulation is the answer

The automotive industry in the US is huge—it brought more than $156 billion to the US economy in 2022, and more than 75 percent of Americans own a car. You’d imagine that such a rich market would include several car brands privacy-savvy users can choose from, but the Mozilla Foundation report is categorical: When it comes to data protection, they’re all bad

This leaves people who need to buy a new car with little choice but to consent to data collection. And it leaves their passengers with even less choice. Because it’s not only luxury vehicles that come equipped with sophisticated sensors and cameras—classic sedans like the Toyota Corolla and family SUVs like the Ford Escape also have them. As much as we’d like to say there’s an individualistic DIY way to snatch back your privacy, there’s not. You’ll have to appeal to the powers that be.

“Get mad and contact your elected officials,” says Caltrider. “It’s past time the US had a strong federal privacy law.”

She also recommends not using your car’s app, but acknowledges that this is a bandage solution and might not be an option for some people. Some of the features people need, like being able to warm the car in cold weather by turning it on remotely, require the use of the software. 

Using our power as constituents and asking our elected officials for laws that protect our data is the best chance we have of taking back the intimacy we once found inside our vehicles. Car companies simply aren’t going to change on their own—just like tech companies, they have no incentives to do so.

The car's smart software knows exactly how to employ the Vette's new electric motor. Here's how it all works.

There used to be a joke that if Microsoft made cars, your car would crash twice a day for no reason at all. But the reality of software-defined cars (that is, vehicles in which clever coding has as much say as masterful machining in determining a car’s characteristics) is demonstrated by the 2024 Chevrolet Corvette E-Ray, whose smart software lets the car’s new electric motor deliver supplemental power to the front wheels so imperceptibly that the driver would have trouble guessing that the latest version of America’s sports car has all-wheel drive.

That’s because the Corvette’s signature 6.2-liter, overhead-valve, LT2 small block V8 is still roaring, powering the rear wheels with its 495 horsepower, just like in the base Stingray model. But now there’s that 160-hp electric motor up front, running off a 1.9 kilowatt-hour array of LG lithium-ion batteries deftly tucked into the car’s central tunnel.

This $104,295 vehicle is a regular hybrid-electric, with no external power plug, so the battery is small and gets its juice entirely from the gas engine and from regenerative braking that turns the electric motor into a generator when the car slows. Having that extra 160 hp and 125 lb.-ft. torque on tap is “like having a nitrous oxide tank that fills itself,” remarked chief engineer Josh Holder, referring to the “NOS” gas made famous by The Fast and the Furious movie franchise for giving combustion engines a burst of extra power.

The quickest Corvette ever

But rather than the explosive power delivery from NOS, the E-Ray’s omnipresent electric motor “torque fill” just makes the car constantly more muscular. This power, combined with the traction of all-wheel-drive, makes the E-Ray the quickest Corvette ever, with a 0-60 mph acceleration of 2.5 seconds and a 10.5-second quarter mile time.

Those times are achieved using the E-Ray’s Performance Launch mode, which uses the car’s various software-controlled systems to optimize power delivery from the gas and electric motors to deliver the fastest possible acceleration.

The driver can keep the E-Ray’s battery topped off so that it is ready to deliver that boost by pressing the Charge+ button. If you ever watch Formula 1 races, you’ll see a car’s rear light flashing when the driver is building the state of charge in its battery in preparation for a passing attempt on a car ahead. The E-Ray’s Charge+ button on the center console, down by the driver’s right thigh, ensures that the battery’s virtual NOS tank is fully topped off with electrons.

The Corvette Z06 we tested last year is nearly as quick, but that car produces its power with more noise and drama. The E-Ray appeals to the enthusiast who wants a comfy ride that also happens to be ludicrously fast. And if you need to sneak out of your neighborhood in the morning without annoying the neighbors, let the small block V8 sleep late and cruise out on electric power alone using Stealth mode to reach speeds as high as 45 mph.

Other driving modes with pre-set performance parameters include Tour, Sport, Track, and Weather. Each of those optimizes the car’s sound, power delivery, stability control, traction control, and dynamically adjustable magnetic suspension damping to match those conditions. Additionally, drivers can select their own preferences in My Mode and Z Mode.

Driving the Corvette E-Ray on and off the track

The E-Ray rolls on the same wide wheels wrapped in meaty Michelin rubber and enclosed by the same 3.6-inch wider fenders as the Z06, but the rubber on those wheels is Michelin’s Pilot Sport all-season tire to make the E-Ray compatible with rain and snow. I didn’t encounter those conditions on the roads around Denver or during my track drive at Pikes Peak International Raceway, but I could feel the E-Ray’s stability and surefootedness.

In addition to the all-weather tires, the E-Ray is also available with the same Michelin Pilot Sport 4S summer tires as are used on the base Stingray version. And as on that car, these excellent tires provide the consistent grip, comfort, and durability drivers want in everyday driving. And as I found track testing the Stingray, these tires are really not at home on the track, where they quickly turn hot and greasy compared to true track tires, losing their grip after thrashing through just a few hard corners.

No matter, that’s not the E-Ray’s purpose. Yes, it is fast, but the similarly priced Z06 ($111,295) is the weapon of choice for track rats. The E-Ray is for drivers who want that kind of speed in a car they can enjoy every day in comfort.

Even with its all-wheel-drive traction, the E-Ray is not penalized by sluggish steering response on corner turn-in, as is typically the case with cars that route power through the front wheels. That’s because the computer is smart enough to know when and how much power to send from the electric motor to the front wheels.

It can even let the driver induce a drift in corners, spinning the rear wheels without the front-drive power interfering with the sideways-sliding fun. That car-straightening front power is welcome when driving home from work in bad weather, but it can spoil the fun on the track, so the E-Ray knows when to have the electric drive step back and let the V8 do the work.

A weighty issue 

Just as the E-Ray rolls on the same wide wheels as the Z06, it also packs the same Brembo carbon ceramic brakes inside them to help slow the car. This is in addition to the E-Ray hybrid-electric regenerative braking, which does much of the car’s stopping. 

But the big brakes are important, because while the hybrid system adds braking power, it also adds mass. Chevrolet says the E-Ray weighs 3,774 pounds as a coupe and 3,856 pounds as a convertible, which means that it is about 350 pounds heavier than the Z06 and 400 pounds heavier than the Stingray.

This is in spite of a huge effort by the car’s engineering team to minimize the weight penalty of the electric motor and battery pack. “We put the highest bounty on weight of any car we’ve ever done,” recalled Holder. Even with that effort, electric motors and batteries are still heavy. “It is the heaviest Corvette we’ve ever done,” Holder acknowledged, adding, “but it is the lightest hybrid we’ve ever done.” 

The E-Ray matches the slower Stingray’s EPA fuel economy rating of 19 mpg in combined driving, with a score of 16 mpg city and 24 mpg highway. The Z06’s rating depends on the exact equipment, but it is either 14 mpg or 15 mpg in combined driving. City driving in either case is a dismal 12 mpg.

The added mass is low in the chassis, with the electric motor between the front wheels and the battery pack in the central spine running between the seats in the cockpit, so the center of gravity is low. Engineers mask that weight with savvy chassis control with the magnetically controlled adaptive dampers and the aforementioned massive brakes, so the E-Ray never feels heavy on the road.

As with the seamless power delivery, credit the brainy calibration by the Corvette team’s programmers in creating the reality of their choice rather than the one suggested by physics. It turns out that software-defined vehicles are far better than the old Microsoft joke predicted.

How seriously can we take Tesla and Rivian’s right-to-repair pact? https://www.popsci.com/technology/tesla-rivian-right-to-repair/ Tue, 17 Oct 2023 10:00:00 +0000 https://www.popsci.com/?p=580020

Despite a “landmark” agreement, automakers and the repair industry are still fighting over who controls car data.

Leading American electric vehicle makers Tesla and Rivian are supporting a controversial pact between carmakers and automotive repair organizations that critics say is an attempt to undermine legislation that would make it easier for Americans to fix their cars.

For several years, the American car industry has been feuding with automotive service groups and right-to-repair advocates over who should control access to telematic data, information about speed, location, and performance that cars transmit wirelessly back to their manufacturers. Many in the automotive repair industry say this data is essential for fixing today’s computerized cars, and that it should be freely available to vehicle owners and independent shops. Increased access to telematic data, repair advocates argue, will drive down the cost of repair and keep vehicles on the roads for longer. This is particularly important for EVs, which must be used as long as possible to maximize their climate benefits and offset the environmental toll of manufacturing their metal-rich batteries.

These arguments have led members of Congress from both parties to introduce a bill called the REPAIR Act that would grant car owners, and the mechanics of their choosing, access to their telematic data. But the auto industry, which stands to make billions of dollars selling telematics to insurers, streaming radio services, and other third parties, contends that carmakers should be the gatekeepers of this data to avoid compromising vehicle safety. 

In July, ahead of a congressional hearing on right-to-repair issues, an automotive industry trade group called the Alliance for Automotive Innovation announced it had struck a “landmark agreement” with repair groups regarding telematic data sharing — an agreement that ostensibly preempted the need for legislation. A few weeks later, Tesla and Rivian, neither of which is a member of the Alliance for Automotive Innovation, announced their support for the agreement. The only problem? Major national organizations representing the automotive aftermarket and repair industries weren’t consulted about the agreement, don’t support it, and claim it won’t make cars easier to fix.

The new agreement “was an attempt by the automakers to distort the facts of the issue and create noise and confusion in Congress,” Bill Hanvey, president of the Auto Care Association, a national trade association representing the aftermarket parts and services industry, told Grist. The Auto Care Association is among the groups that was not consulted about the agreement.

This isn’t the first time the auto industry and repair professionals have reached a voluntary agreement over right-to-repair. 

In 2002, the Automotive Service Association, one of the signatories on the new agreement, struck a pact with vehicle manufacturers to provide independent repair shops access to diagnostic tools and service information. Then, shortly after Massachusetts passed the nation’s first right-to-repair law focused on vehicles in 2013, manufacturers and organizations representing the aftermarket, including the Auto Care Association, signed a memorandum of understanding, or MOU, nationalizing the requirements of the law. That law granted independent mechanics explicit access to vehicle diagnostic and repair information through an in-car port. 

Gay Gordon-Byrne, executive director of the right-to-repair advocacy organization Repair.org, believes automakers signed the 2014 MOU “in order to prevent more legislation—and particularly more legislation that they would not like.” Automakers objected to including telematics in the 2014 MOU, according to Hanvey. “Because, at the time, the technology was so future-looking, the aftermarket agreed to get a deal in place,” he said.

Telematics is no longer technology of the future, however. Today, manufacturers use telematic systems to collect reams of real-time data related to a vehicle’s activity and state of health, potentially allowing manufacturers to evaluate cars continuously and encourage drivers to get service from their dealers when needed. Independent mechanics, meanwhile, need drivers to bring their vehicles into the shop in order to read data off the car itself—if the data is accessible at all.

In 2020, Massachusetts voters passed a ballot measure called the Data Access Law requiring carmakers to make telematic repair data available to owners and mechanics of their choosing via a standard, open-access platform. Shortly after voters approved it, Alliance for Automotive Innovation sued Massachusetts to stop the law from going into effect, arguing that it conflicted with federal safety standards. The federal judge overseeing the lawsuit has delayed ruling multiple times, keeping the requirements in legal limbo for nearly three years. In June, Massachusetts Attorney General Andrea Campbell decided to begin enforcing the law, lawsuit notwithstanding. 

While fighting Massachusetts’ Data Access Law in court, automakers were also negotiating their own rules on data sharing. The agreement that the Alliance for Automotive Innovation announced in July included the imprimatur of two repair groups: the Automotive Service Association, a not-for-profit advocacy organization that lobbies states and the federal government on issues impacting automotive repair, and the Society of Collision Repair Specialists, a trade association representing collision repair businesses. 

Dubbed the “Automotive Repair Data Sharing Commitment,” the new agreement reaffirms the 2014 MOU by requiring carmakers to give independent repair facilities access to the same diagnostic and repair information they make available to their authorized dealers. In a step beyond the 2014 MOU, the new agreement includes telematic data required to fix cars. But carmakers are only required to share telematic repair data that “is not otherwise available through a tool,” like the in-car port used today, “or third party-service information provider.”

Because of those caveats, critics say, the agreement effectively changes nothing about telematic data access: Carmakers are still able to decide what data to release, and in what format. Independent shops may still be forced to read data off cars that manufacturers and their dealers have immediate, over-the-air access to, or they may have to subscribe to third-party services to purchase data that dealers receive at no charge. 

What’s more, the qualification about dealerships suggests Tesla and Rivian wouldn’t have to provide any telematic data whatsoever, since neither company works with dealers. That’s especially problematic, Hanvey said, considering both companies make cars that rely heavily on telematic systems. In a pair of class action lawsuits filed earlier this year, Tesla customers alleged that the company restricts independent repair by, among other things, designing its vehicles so that maintenance and repair work rely on telematic information Tesla exclusively controls. 

“The EVs are much more technological, much more reliant on code, and the repairs are much more complicated,” Hanvey said. “It’s difficult enough getting them repaired today, and if you take out the aftermarket, it’s going to be even more challenging for consumers.” 

Neither Tesla nor Rivian responded to a request for comment.

The voluntary nature of the agreement weakens it further, critics say. The Massachusetts Data Access Law and the REPAIR Act under consideration in Congress—which would also require manufacturers to give vehicle owners direct, over-the-air access to telematic repair data via a standard platform—would carry the force of law. By contrast, “there’s no distinction about what happens if this MOU is violated,” Hanvey said. 

Gordon-Byrne told Grist in an email that carmakers haven’t universally complied with the 2014 MOU. “And outside of Massachusetts there isn’t any statute to force compliance,” she said. 

“The problem,” Gordon-Byrne continued, “is lack of enforcement. If the parties don’t like the arrangement—they can talk about it once a year.” Indeed, the new agreement includes a yearly review of the terms by the signatories, as well as the establishment of a panel that will meet biannually to discuss any issues parties have raised regarding repair information access and to “collaborate on potential solutions where feasible.”

The Automotive Service Association and the Society of Collision Repair Specialists don’t represent all of the stakeholders who care about telematic data, which in addition to carmakers, dealers, and mechanics, includes companies that sell and distribute aftermarket parts. In fact, these two signatories appear to represent a small slice of the auto repair industry, which included more than 280,000 U.S. businesses this year, according to market research firm IBIS World. The Automotive Service Association did not provide membership numbers when Grist asked, but there were 1,243 U.S.-based businesses listed in its online directory as of this week. (Several major carmakers are also affiliated with the group, including Nissan, Ford, and Audi.) The Society of Collision Repair Specialists, which didn’t respond to Grist’s request for comment, includes approximately 6,000 collision repair businesses, according to its website

The Auto Care Association, meanwhile, represents over half a million companies that manufacture and sell third-party vehicle parts, and service and repair cars. And it’s not the only group that feels the new agreement doesn’t go far enough: So does the Tire Industry Association, which represents roughly 14,000 U.S. member locations that make, repair, and service tires, MEMA Aftermarket Suppliers, representing several hundred aftermarket parts manufacturers, and the Auto Care Alliance, a group of state and regional auto service provider networks with 1,200 members across the country. None of these groups was consulted in advance about the new agreement.

The data sharing agreement “is history repeating itself once again,” Ron Turner, director of the Mid-Atlantic Auto Care Alliance, said in a statement, referring to the voluntary industry agreements of 2002 and 2014, which the organization claims stymied national legislation and have not been adequately enforced. The groups promoting it, Turner said, “are slowing down much-needed legislation and enforcement the automotive industry has needed for decades.”

The Alliance for Automotive Innovation feels differently about voluntary agreements. Brian Weiss, vice president of communications at the trade organization, told Grist in an email that the 2014 MOU “has been working well for almost a decade” and the new data-sharing agreement builds off it. Weiss declined to respond to specific criticisms of the agreement, offer examples of telematic data that carmakers would have to release as a result of it, or explain why the Auto Care Association, a signatory on the 2014 agreement, wasn’t included in the new one.

Robert Redding, a lobbyist for the Automotive Service Association, told Grist that voluntary agreements have worked for its members, too, citing the service information agreement the group negotiated with carmakers in 2002. (The Automotive Service Association was not a party to the subsequent 2014 MOU.) The new agreement, Redding said, was the result of a yearlong negotiation process, and he believes parties came to the table “in good faith.”

“We feel very good about the agreement,” Redding said. “This worked for service information, and we believe it’ll work for vehicle data access.” 

The groups backing the new agreement are already using it to argue that further regulation is unnecessary. In a September 22 court filing in the lawsuit concerning the Massachusetts Data Access Law, the Alliance for Automotive Innovation touted the agreement as evidence of the car industry’s “ongoing effort to ensure that consumers enjoy choice with respect to the maintenance and repair of their vehicles.” 

Several days later, at a September 27 hearing of the House Energy Subcommittee on Innovation, Data, and Commerce, Automotive Service Association board of directors chairman Scott Benavidez testified that the new data sharing agreement “nullifies the need for the REPAIR Act.” It was similar to an argument the group made nearly 20 years earlier when it opposed a national right-to-repair act for vehicles, arguing that the voluntary agreement it negotiated with carmakers in 2002 rendered legislation unnecessary.

Dwayne Myers, CEO of Dynamic Automotive, an independent auto repair business with six locations in Maryland, was disappointed to see the Automotive Service Association publicly oppose the REPAIR Act. Myers has been a member of the organization for about a decade, but he says he wasn’t consulted about the new agreement in advance of its release and he doesn’t believe it should be used to undermine laws guaranteeing access to repair data.

“They could have just remained quiet and let their MOU sit there—they didn’t have to oppose the right to repair,” Myers said. “To me it just felt bad. Why as an industry aren’t we working together, unless you’re not on our side?”

Military transport vehicles have to withstand a range of tests to show they can protect their occupants. Take a look at how that happens.

The post Watch this new Canada-made troop transport pass its explosive tests appeared first on Popular Science.

On May 30, Canadian defense company Roshel Defence Solutions officially launched its new armored troop transport, the Senator model Mine Resistant Ambush Protected (MRAP) vehicle. Part of the launch was surviving a series of tests to prove that the vehicle can protect its occupants. 

The testing was conducted by Oregon Ballistic Laboratories and done to a standard called NATO “STANAG 4569” level 2. (STANAG means “standard agreement,” and 4569 is the numbering of that agreement.) What that means in practice is that the Senator MRAP is designed to withstand a range of the kinds of attacks that NATO can expect to see in the field. These include bullet fire from calibers up to 7.62×39mm at roughly 100 feet (30 meters). Why 7.62×39mm caliber bullets? That’s the standard Soviet bullet, which has outlasted the USSR itself and is common in weapons used across the globe.

In addition, STANAG 4569 dictates that the vehicle must survive a 13 pound (6 kg) anti-tank mine activated under any of the vehicle’s wheels, as well as survive a mine activated under the vehicle’s center. Beyond the bullets and mines, the vehicle also has to withstand a shot from a 155mm high explosive artillery shell burst landing 262 feet (80 meters) away. 

All of this testing is vital, because a troop transport has to advance through bullet fire, keep occupants safe from mines, and travel through an artillery barrage. That NATO standards are designed to withstand Soviet weapons is a convenience for any equipment exports aimed at Ukraine, but also means the vehicles are broadly useful in conflicts across the globe, as an abundance of Soviet-patterned weaponry continues to exist in the world. 

To showcase the Senator MRAP in simulated attack, Roshel released two videos of the testing. The first, published online on May 29, features a bright green checkmark in the corner, “all tests passed” clearly emblazoned on the video as clouds of destruction and detonations appear behind it.

Army photo

A second video, released June 16, shows the Senator MRAP in slow motion enduring a large TNT explosive hitting it on the side. The 55 lbs (25kg) explosive is a stand-in for an IED, or Improvised Explosive Device. IEDs were commonly used by insurgent forces in Iraq against the United States, and in Afghanistan against the NATO coalition that occupied the country for almost 20 years. While anti-tank mines tend to be mass-produced industrial tools of war, IEDs are built on more of a small scale, with groups working in workshops generally assembling the explosives and then placing them on patrol routes.

It was the existence of IEDs, and their widespread use, that prompted the United States to push for, develop, and field MRAPs in 2006. Mine Resistant Ambush Protected vehicles were not a new concept. South Africa was one of the first countries to develop and field MRAPs in the 1970s, putting essentially a V-shaped armored transport container on top of an existing truck pattern. The resulting “Hippo” vehicle was slow and cumbersome, but could protect its occupants from explosives thanks to the V-shaped hull deflecting blasts away. 

MRAPS did not guarantee safety for troops on patrol, but they did drastically increase the amount of explosives, or the intensity of attack, needed to ambush armored vehicles.

“The presence of the MRAP also challenged the enemy, since the insurgents had to increase the size of their explosive devices to have any effect on these more survivable vehicles. The larger devices, and longer time it took to implant them, increased the likelihood that our troops would detect an IED before it detonated,” Michael Brogan, head of the MRAP vehicle program from 2007 to 2011, told the Navy’s CHIPS magazine in 2016.

The Senator MRAP features, like its predecessors, a V-shaped hull. It also benefits from further innovations in MRAP design, like mine-protected seats, which further reduce the impact of blast on their occupant. Inside, the Senator can transport up to 10 people, and Roshel boasts of its other features, from sensor systems to weapon turrets. For as long as IEDs and mines remain a part of modern warfare, it is likely we can expect to see MRAPs transporting soldiers safely despite them.

The Lamborghini Revuelto is a hybrid with a V12 engine, three motors, and six miles of all-electric range.
The Lamborghini Revuelto is a hybrid with a V12 engine, three motors, and six miles of all-electric range. Lamborghini

Lamborghini, the brand that started making supercars to compete with Ferrari 60 years ago, is starting a new era. Steeped in a history of loud and powerful V8, V10, and V12 engines, the Raging Bull has launched its first “high performance electrified vehicle,” a hybrid called Revuelto

While watered-down performance may be a possibility for some mass-produced cars, that’s not going to fly for Lamborghini. Instead of backing down to a smaller engine and tacking on an electric motor, the brand opted to attach two motors to the front and one to the back and matched them to a new V12, the lightest one the automaker has ever built. Then Lamborghini whipped up a recipe for a battery that regenerates so quickly that it never gets all the way down to zero, and added a plug-in port for good measure.

All in, the system adds up to an astonishing total of 1,001 horsepower and more than 800 pound-feet of torque. That officially makes it the most powerful plug-in hybrid on the market. Lamborghini started from the ground up for this car, fashioning a new carbon fiber structure (picture a Lego base plate upon which brick houses are built) made to be as light as possible. And then it went to work making sure the Revuelto was as technologically advanced as it could be with its electronics.

To top it off, the Revuelto is also registering a significant emissions reduction, which Lamborghini says tops 30 percent over its predecessor, the Aventador. For a supercar, this is a big deal. The Revuelto is capable of about 6 miles in all-electric range, which loud-engine-averse neighbors will appreciate as the car pulls away in silence. 

Can the Revuelto still carry the brand’s name with pride, even as a hybrid? Here’s what we think after driving it on the Autodromo Vallelunga track in Rome, Italy.  

Melding design and engineering

Hybrids are hot right now, as are EVs. But Lamborghini has not gone soft and bent to the market, says the brand’s chief technical officer, Rouven Mohr. The small-batch automaker has created a hybrid that harnesses electric power without diluting the car’s core power, and that’s no small feat.

“To us, hybrid doesn’t mean sacrificing performance,” Mohr says.

Mohr, along with his team and the stylings of head of design Mitja Borkert, started with the V12 engine as a centerpiece. Lamborghini fans equate the sound of its iconic powerplant with the full experience, and erasing that part of the brand’s DNA wasn’t an option, Mohr emphasizes. 

Borkert also went to work creating a body shape that evokes ghosts of models past. After commissioning 17 exploratory models that filled up his studio, Borkert took inspiration from Lamborghini’s Countach and Diablo, along with elements from fighter jets and Ducati superbikes. He raised the roof and added more legroom than the Avendator, the Revuelto’s predecessor, making it easier to get in and out.

[Related: The new Lamborghini Revuelto is a powerful hybrid beast]

Along with a riot of Y-shaped designs repeated throughout the car on the headlamps and on the dash, Borkert suggested an opening that leaves the engine bay exposed. Not only does it look cool, he says, it serves an important purpose: natural engine cooling. Lamborghini also opted to implement a long, skinny battery that is easily cooled from the outside to the center; heat management is a key factor for performance.

Tire-maker Bridgestone contributed to the Revuelto by creating bespoke performance Potenza Sport tires with wide footprints and grippy tread, especially the top-level option that is equally capable on the road as they are on the track.

“It’s not an easy car to fit tires,” Mohr says. “It weighs more [than the Aventador] and the power profile is huge.”

Lamborghini zooms in on technology

Lamborghini may have been seen more for its muscle and brawn than its brains in the past, but that’s changing, as well. The new Revuelto features intelligent torque distribution that balances the weight precisely from side to side and front to back so that cornering feels planted.

Aventador enthusiasts may say the Revuelto loses the raw edge of its older sibling, but after a day on the track, I say the new setup polishes the diamond. Even hurling the car toward the corner after a breathtaking straightaway, I never felt as though I could lose control. The massive carbon ceramic brakes gave the hybrid the stopping power it needed and gave me the confidence to push it. 

Plus, the infotainment system upgrade is the best I’ve seen in a Lamborghini, equipped with Alexa connectivity and a set of widgets on the modest screen that can be rearranged and shared with the passenger on their own screen.

The real test is on the road and the track. While Lamborghini says it isn’t pursuing the crown for the fastest car on the planet (Mohr wryly says the race for best lap times in the supercar world is a “little bit crowdy” at the moment), it’s still lightning quick. But the best part is the feel of the drivetrain, which is completely seamless between the V12 and its electric helpers. Pressing the accelerator down in Corsa (track) mode and getting to 150 miles per hour on a straightaway is ridiculously smooth and quick. Top speed in the new supercar is 350 kilometers per hour (about 218 miles per hour).

Lamborghini is looking toward the future with the Revuelto, and it’s looking very good. The brand has been logging record sales, and with an all-electric concept—the Lanzador—on the table and a plug-in Urus SUV confirmed, it’s not looking back.

It has been more than two years since former Audi CEO Markus Duesmann announced that after 2026, the automaker will develop only battery-powered models. Audi’s plan is to have more than 20 fully electric models in its portfolio by 2025. The carmaker has already started down this road by investing about 18 billion euros ($19 billion and change) in electrification and hybridization.

In the process, Audi is pursuing battery technology that optimizes energy efficiency. Its primary focus for innovation is solid state batteries, which use solid electrolytes instead of liquid. The brand designs, develops, and checks battery cells and battery components on its own at its battery testing center in Gaimersheim, Germany. It recently transitioned its battery packs from winding to a stacking configuration, where the cells are stacked neatly, like a layer cake, to increase the overall capacity. 

More capacity means greater range. And better range makes these vehicles more marketable in a competitive, burgeoning market. Any advantage between today and the sometime-in-the-future implementation of solid state batteries is a coveted position. 

Here’s how it works.

Stacking adds density, thus energy

The German brand is known for agile, sleek vehicles that consistently earn high marks for performance and handling. As part of the Volkswagen group along with Porsche and even Lamborghini, Audi is in good company. Audi (along with the other brands in the group) has ratcheted up its EV goals, seeking the best ways to leap ahead of its competitors, and battery stacking is the latest mark of progress.

[Related: Why solid state batteries are the next frontier for EV makers]

In new EVs like the Q8 e-tron, electrodes in lithium-ion cells are thin foils which are traditionally wound into a structure called a jelly roll, Audi explained to PopSci. These jelly rolls can be either round for cylindrical cells or flat for prismatic cells. In prismatic cells, the utilization of the inner volume is limited due to the rounded edges.

By stacking single electrode sheets into larger stacks, more of the cell’s inner volume can be used, increasing the cell’s capacity. This allows Audi’s EVs to make better use of the physical space per cell, as was previously the case with winding technology.

Imagine it this way: in winding, the cell material is wrapped around a roll and squeezed together into a rectangular shell. During stacking, the electrode layers are superimposed to completely fill the rectangular space so that the cell has about 20 percent more active material, which increases the capacity. Cramming more electrons into the space equals overall improved range. A total of 12 battery cells form a module and 36 modules make up a battery system, protected by cube-shaped aluminum housing.

For the Q8 e-tron SUV and Sportback, Audi engineers created a battery pack that delivers about 20 kilowatt hours more gross capacity over 2023 models. Now, the battery offers 114 kWh instead of the 95 kWh on the previous battery tech. And incredibly, it doesn’t take up any more space than the old battery pack. As a result, 2024 Q8 e-tron owners can get 30 percent more range. The Q8 Sportback S-Line e-tron with the ultra package gets 300-plus miles. Even the standard Q8 e-tron SUV is good for 285 miles (296 for the Sportback) so it’s pretty close. 

The 2023 model served up a 222-mile EPA-estimated range for the standard SUV and 218 miles in Sportback form. For the 2024 Q8 e-tron, the EPA estimates it’s good for 285 miles for the SUV and 296 miles for the Sportback model. An optional Ultra package, available only with the Sportback, features a smaller wheel and tire package with low-rolling-resistance rubber and retuned suspension that gives it a lower ride height for added efficiency, and this setup delivers the magical 300-mile EPA estimate.

Pros and cons to stacking 

Like most new technologies, there are advantages and disadvantages to consider, Audi says. The advantage of this new stacking method allows for more active material to be implemented into lithium-ion cells, resulting in greater capacity, energy, and power. The disadvantage is a slower production process, resulting in higher cost.

Ultimately, Audi opted to prioritize the advantages over the disadvantages, a brand representative shared with PopSci.

Audi cell technicians had a dual goal of packing as much energy as possible into the stack while still having the ability to recharge it as quickly as possible. However, more density requires more time to charge compared to previous, less-dense batteries. This latest achievement also comes with a side of improved battery chemistry that Audi says has a better charge curve, which allows it to hold higher charging rates for longer.

At its battery testing site in Gaimersheim, Audi also runs a construction facility for prototype batteries. Here, employees build the high-voltage batteries from the ground up all the way to pre-series production. The goal for the next iteration will involve greater integration of the cells into the battery pack, reducing overhead, optimizing the battery’s design, and increasing the overall vehicle’s efficiency with the newest cell technologies.

As I’m riding through the wilds of southwest Colorado, up through Cinnamon Pass at over 12,000 feet in altitude, I’m thinking about the suspension on the Polaris Xpedition UTV (utility task vehicle) I’m piloting.

Yes, of course I’m also intently focused on the dirt road as we navigate across narrow cliffside paths and splash through mud puddles. But the premium Fox shocks in this off-road vehicle keep my tires planted as they flex with the ground beneath me, absorbing the dips, bumps, and rocks at an impressive rate. The all-new Xpedition, launched this May, seems to eat rocks for breakfast, lunch, and dinner. Here’s how it does that. 

Machined shocks 

Outdoorsy people—those who like camping, fishing, hunting, hiking, biking, and more—occupy Polaris’ sweet spot. The company says the 2024 Polaris Xpedition is best described as an “adventure side-by-side” as opposed to the utility vehicles used on ranches and farms or the recreational vehicles you might see tearing across sand dunes in California. Side-by-side in this case means it has at least two seats, which you don’t see in some all-terrain vehicles like quad bikes or snowmobiles.

This vehicle has a flat roof made for carrying kayaks, fishing poles, traction boards, and rooftop tents, all available as accessories. After driving the Xpedition all day and then testing out the rooftop tent to camp out next to a waterfall, I concur that it checks all the boxes. When carrying just two people, the vehicle’s second row can be folded down to hold even more stuff, or the Xpeditioncan accommodate five people and less cargo. It’s also now available as a completely-enclosed UTV with both warm and cool climate control, the only side-by-side on the market to do so.

“We started from the ground up with a one-piece frame, which is going to make it a lot stronger,” Polaris sales manager Eric Borgen says. “Our older products had frames that would bolt together in the middle; having that one piece frame is obviously going to make it a lot more rigid, which is also going to help make sure that our roll cage doesn’t flex.”

Layered into the new frame, the FOX Podium QS3 shocks are one of the key factors for a smooth ride. The shocks use “position sensitive spiral technology,” and that means two things. One, the equipment uses damping force, which controls vibration; and two, spiral grooves inside the shock body allow fluid to flow around the piston assembly, refining the movement.

“If you look inside of the actual shock body and you take it apart and you look down the barrel, it’s very similar to what people do to rifles,” Borgen explains. “They’ve machined a groove—a corkscrew—in the body. So when the piston is going up and down inside the shock body, it allows the fluid to bypass the valving.”

What that means is when driving 20 miles an hour through rocky trails, or over a washboard road, a typical passenger vehicle would toss your head around inside the cabin uncomfortably. With these shocks, the ride in the Xpedition is smoothed out in a noticeable way. Instead of a handful of zones that get progressively stiffer, the UTV’s shocks are machined for a consistently composed ride for the passenger at various speeds and road conditions. Indeed, the only time I felt a significant impact across 100 miles in the San Juan mountains was when a rock got loose under me and hit the underside. The Xpedition crunched along and left it in the dust.  

GPS off the grid

One thing that can strike fear into the heart of a new off-roader is getting lost. As more and more people explore the great outdoors (the trend has ticked noticeably upward in the last several years) they’re looking for ways to do it safely, and Polaris’ contribution to that is its Ride Command technology. 

Ride Command provides a built-in GPS navigation and wayfinding system that works even if you’re out of cell coverage zones. It includes a million-plus miles of verified trails and allows riders to plan a route before heading out. Even more importantly, it can be set up as a group ride so the vehicles can band together and see each other on the map as a color-coded dot. 

As Borgen, a desert-racing champion himself, led our group on a pre-established route, I could see at a glance on the map display in front of me how far ahead he was and what speed he was going. As a result, if I saw that he was slowing way down to let vehicles pass from the other direction (riders going uphill have the right-of-way on the trails) I could adjust even before I could see him through my windshield.  

There is one thing Borgen tells our group before we set out, and it’s the most important thing we need to know above and beyond all of the technology and engineering: how to be a considerate off-road driver. Some drivers have sparked animosity by going too fast on the trails and creating an uncomfortable environment for others, squarely placing a spotlight on the industry. 

The Polaris representative stresses the magnitude of being a considerate consumer, watching out for those who don’t like the noise and the dust off-highway vehicles carry with them. In that vein, the company is working toward more electric vehicles, like its new 2024 Ranger XP Kinetic. 

“Hikers are trying to enjoy the public land too,” he says. “So slow down; don’t dust ’em out, please. We don’t want to ruin our places to ride, because even though Jeeps and dirt bikes and side-by-sides are all different, we’re all doing the same thing and we all need to work together to maintain our lands.”

EVs have a tire particle problem https://www.popsci.com/environment/problem-evs-tires/ Tue, 26 Sep 2023 01:00:00 +0000 https://www.popsci.com/?p=574186

As gas-guzzling cars are replaced by their electric counterparts, tailpipe emissions are on the decline. But cars have other negative impacts on environmental health, beyond what comes out of their exhaust pipes.

One of the bigger, and lesser known, problems is tire pollution—or “tire and road wear particles,” in industry terminology.

Tires shed tiny particles with every rotation. Tire wear happens most dramatically during rapid acceleration, braking, and sharp turns, but even with the most conservative driving, particulate pollution is an unavoidable consequence of car use. And it’s a problem that’s poised to get worse as drivers transition to EVs.

“We’re pushing for decarbonization by going to battery electric vehicles, and in doing so we’re pushing up tire wear emissions … which is going to prove difficult to solve,” said Nick Molden, founder and CEO of Emissions Analytics, a London-based company that performs independent tests on cars’ real-world tailpipe and tire emissions. Molden pointed out that tailpipe exhaust is dramatically reduced by filters and catalytic converters, which use chemical reactions to reduce pollution. Meanwhile, tires are a fundamentally open system, so there is no viable way to capture the polluting particles that fly off of them.

Emissions Analytics found that a single car sheds almost nine pounds of tire weight per year, on average. Globally, that amounts to six million metric tons of tire pollution annually, with most of it coming from wealthier countries where personal car use is more prevalent.

The amount of tire pollution emitted per vehicle is increasing as more electric cars hit the road around the world—some 14 million of them this year, according to the International Energy Agency. EVs tend to be significantly heavier than gas-powered or hybrid cars due to their larger, heftier batteries. The average battery for an EV on the market today is roughly 1,000 pounds, with some outliers approaching 3,000 pounds—as much as an entire gasoline-powered compact car. Emissions Analytics has found that adding 1,000 pounds to a midsize vehicle increased tire wear by about 20 percent, and also that Tesla’s Model Y generated 26 percent more tire pollution than a similar Kia hybrid. EVs’ more aggressive torque, which translates into faster acceleration, is another factor that creates more tire particulate mile for mile, compared to similar internal combustion engine cars.

Tire particulate is a toxic slurry of microplastics, volatile organic compounds, and other chemical additives that enter the air, soil, and water around trafficked areas. The rubber, metals, and other compounds coming off tires settle along roads where rain washes them into waterways. Smaller bits of tire particulate linger in the air, where they can be inhaled, and the smallest of this particulate matter—known as PM 2.5, because each particle is 2.5 micrometers or less — can directly enter the bloodstream. A 2017 study estimated that tire wear is responsible for 5 to 10 percent of oceanic microplastic pollution, and 3 to 7 percent of airborne PM 2.5 pollution. 

One particularly concerning chemical in tires is 6PPD, which is added to virtually all tires to prevent rubber from cracking. But in the environment, 6PPD reacts with ozone to become 6PPD-quinone, a substance that has been linked to salmon die-offs in the Pacific Northwest. A 2022 study confirmed the compound is also lethal to rainbow trout and brook trout.

Further research has shown that the chemical is absorbed by edible plants like lettuce and has the potential to accumulate in them. A study in South China found both 6PPD and 6PPD-quinone in human urine samples. The human health effects of the chemical are not yet understood, but other chemicals found in tires have been linked to problems ranging from skin irritation to respiratory problems to brain damage.

Given the intensifying realities of climate change, phasing out gas-powered vehicles rapidly is a must. But experts say the U.S. and other wealthy countries can accomplish this while also mitigating the environmental and health problems caused by EVs’ increased tire wear—namely by curbing car use overall.

Foremost, local policymakers can take steps to make U.S. cities less cripplingly car-dependent. Although that might sound like a daunting task, there’s historical precedent: The Netherlands used to be dominated by cars and experienced a higher rate of traffic fatalities than the U.S., until activist groups like Stop de Kindermoord (“Stop Child Murder”) mobilized in the 1970s to let policymakers know that they wanted less traffic on their streets. According to Chris Bruntlett, the co-author of Building the Cycling City, policymakers created the low-traffic, bike-friendly Dutch cities we know today by instituting traffic-calming measures. “Officials started with speed-limit reductions, parking restrictions, through-traffic limitations, and lane narrowings and removals,” Bruntlett told Grist.

David Zipper, a mobility expert and a visiting fellow at the Harvard Kennedy School, says that city leaders can also remove subsidies for car ownership, such as free residential parking on public streets. “Once car subsidies are removed, fewer people in cities will choose to buy and own them,” Zipper said.

Of course, measures to reduce car use only work in tandem with investments in alternative transportation. The Infrastructure Investment and Jobs Act of 2021 provided some federal funding for transit and pedestrian and bike infrastructure, but making the most of these funds will require political will from state and local lawmakers. Zipper said that policymakers in some U.S. cities have begun to take positive actions—like Boston Mayor Michelle Wu, who has committed to expanding her city’s bike lane network until 50 percent of the population lives within a three-minute walk of a bike lane.

Another way to reduce tire pollution is to trade big, heavy cars for smaller and lighter ones. Especially in the U.S., cars have grown significantly in size and weight in recent decades. Automakers began promoting SUVs in the 1980s, because a legal loophole allowed vehicles designated as “light trucks” to skirt fuel-efficiency regulations. Nine out of the 10 best-selling cars in the U.S. last year were trucks or SUVs, and the International Energy Agency has found that SUVs were the second largest cause of the global rise in CO2 emissions between 2010 and 2018.

One legislative solution to car bloat is introducing weight-based vehicle taxes, which encourage consumer interest in lighter cars and can be used to offset the cost of increased wear on roads caused by heavier vehicles. France implemented a weight-based car tax in 2021, charging consumers a penalty of 10 euros (about $10) for every kilogram above 1,800 (about 4,000 pounds) that their car weighs. This year, Norway also extended its weight-based vehicle tax to include EVs at a rate of a little more than a euro per kilogram above the first 500 kilograms (about 1,100 pounds) for EVs. Norway also taxes vehicles on their carbon dioxide and nitrogen oxides emissions. Taken together, these three taxes have the combined effect of dramatically incentivizing small electric vehicles

In the U.S., some states already prorate vehicle registration fees based on weight, and Washington, D.C. recently overhauled its registration system to more heavily penalize larger cars. In D.C., owners of cars heavier than 6,000 pounds now have to pay $500 in annual fees. New York state lawmakers also recently introduced legislation that would similarly incentivize smaller cars.  

Regulators can also take steps to minimize the harm caused by tire pollution — and in California, the process has already begun. In October, a new regulation implemented by the state’s Department of Toxic Substances Control, or DTSC, will require manufacturers of tires on the California market to research safer alternatives to 6PPD. Manufacturers that sell tires in the state are obligated to notify DTSC about products containing 6PPD by the end of November. 

Karl Palmer, deputy director of safer consumer products at DTSC, believes that making tire makers conduct an “alternatives analysis” will ultimately result in products that are safer for the environment.

“We’re using California’s market strength to say, ‘If you want to park here, you’ve got to comply with our rules,’” Palmer told Grist.

The McLaren Artura is a 671-horsepower supercar. Operating it at top speeds is not something you do without a helmet and a closed course.

Mclaren artura
The hybrid McLaren Artura is a $289,000 mid-engine supercar. McLaren

Here’s a fast fact you may not know: the Brits have dubbed driving 100 mph “doing the ton.” So it is perhaps appropriate that the British supercar-maker McLaren provided me with the opportunity to go two tons—yes, that’s 200 mph—in the company’s Artura hybrid-electric V6 model.

You remember the Artura from my test drive; it’s a $289,000 mid-engine supercar with 671 horsepower and 531 lb.-ft. torque. McLaren says it’ll accelerate to 60 mph in 3.0 seconds and through the quarter-mile in 10.7 seconds. For reference, if a car can do that run in less than 10.0, drag strips require a protective roll cage.

But when people look at a supercar and ask, What’ll it do? they mean top speed. Could the Artura reach the two tons of 200 mph?

It is hard to achieve top speed because, well, it is illegal on public roads outside portions of the German autobahn, and most race tracks don’t have straights long enough to achieve terminal velocity.

Enter the Sun Valley Tour de Force. This is an annual fund-raising charity event in Idaho’s Sun Valley ski region. With a hiatus for Covid, this year’s event was the sixth running of the Tour de Force, which, in exchange for a $2,950 entry fee, lets drivers take a blast along about a mile and a half of state route 75 just north of Ketchum to see how fast they can go. GPS transponders provide official results. The organization raised $1,000,000 this year for the benefit of The Hunger Coalition in Idaho.

I don’t know about you, but when I envision top speed runs, I think of the vast, desolate salt flats in Nevada and Utah. That’s not this. Route 75 is a rural two-lane highway, the sort that adventurous travelers seek out when avoiding the monotony of interstate driving.

[Related: An inside look at the data powering McLaren’s F1 team]

The road is relatively narrow and has little in the way of a shoulder on either side. The surface is old and uneven. The route isn’t even straight. Or flat!

Instead, the cars launch from a start line and drive about half a mile up a slight hill into a fast, gentle left turn that ends with a quick blind crest and then a drive onto the slightly downhill mile straight that is called Phantom Hill to the finish line. The checkered flags marking the finish are in a place called Frostbite Flats, which sounds like where your game piece goes for punishment in Candyland.

The prospect of driving faster than I’ve ever gone before in this setting is daunting. However, the event’s speed record is 253 mph, set by a driver in a Bugatti Chiron, so it is possible to go very fast on this road.

It is the sort of drive I’ve long since decided I wouldn’t do. Cars tend to become like aircraft with no control surfaces at speeds higher than about 150 mph. A generation ago, Car & Driver magazine senior technical editor Don Schroeder was killed during a 200-mph run on a test track, maybe due to a blown tire or seized wheel bearing.

I’ve briefly touched 180 mph at the end of the front straight at Estoril, former site of the Portuguese Grand Prix, in a McLaren Senna and a Lamborghini Aventador SVJ. Both of those cars have thoroughly sorted aerodynamics that kept them stable and on the ground at those speeds. The McLaren engineers were similarly thorough with the design of the Artura, which gave me confidence that the car wouldn’t take flight. This, and the chance to hit 200 mph, sealed the deal. I’d do it!

There is no practice run, though I did have the chance to drive on the highway the day before to scout the lay of the land and the condition of the asphalt. Talking it over with retired Formula 1 driver Stefan Johansson, who McLaren has brought in to drive another one of their cars, I set the powertrain mode to “Track” and put the suspension model on “Comfort” for compliance on the bumpy two-lane highway.

Event organizers station spotters along the route to watch for wildlife or spectators getting too close to the route and provide me a radio for reports of any trouble ahead. The police close off the road at both ends of the course long enough for each run. Mine will take 52 seconds.

Sliding into the Artura’s driver’s seat, I realize the benefit of gull-wing doors, which open the space above the seat when the door is open so it is easier to get in and out while wearing a helmet. I struggle to get my helmet-clad noggin under the roofline, but I’m comfortable once inside.

I’ve made sure to drive the car in the battery regeneration mode on the way to the event, so the hybrid-electric drive system’s battery pack stands at an 80 percent state of charge for the run. As a plug-in hybrid-electric, the Artura’s battery pack could have been fully charged ahead of time, but I couldn’t get a place to plug it in in the hotel’s garage. The ambient temperature is 50 degrees, perfect for making maximum power from the combustion engine.

Sitting behind the wheel, I can see spectators watching from the boundary 100 yards back from the road. In the tall grass, they look like wildlife photographers on the African savanna. By tradition, the first car away is the fellow with the vintage Volkswagen Rabbit pickup truck. He gets close to 90 mph every year and keeps coming back for more.

Next away is a woman in a modified McLaren 720S, whose 218-mph top speed proves to be the fastest time of the day, as warmer temperatures later prevent her father, the car’s owner, from topping her speed.

Then is Johansson, in the brand-new McLaren 750S. He hits 200 mph on the official scoreboard. Two tons!

Then it is my turn. Officials wave me off from the start line, and the Artura squirms, fighting for traction on the launch. It is at triple-digit speeds almost immediately and I ease off the gas as I bend into the left turn, looking for a clear view when I top the peak of the blind crest.

As I clear the hilltop and mat the accelerator pedal, I can’t even make out the finish line flags in the distance, out there on Frostbite Flats. But I do steal a glance at the speedometer: 172.

That seems like a solid foundation for building speed over the next mile. In the cockpit, the Artura sounds great. A hundred yards away from the road, McLaren Houston general manger Pablo Del-Gado is watching. After my run he excitedly reports that from the sidelines, the Artura’s 120-degree V6 was the best-sounding car of the day.

Now at serious speed, I place the Artura in the center of the road. Fortunately, as an arid area, Idaho builds very little water-draining crown into their roads, so there is no concern about getting too far from the centerline and having the car tug its way toward the ditch.

The Artura’s suspension absorbs the bumps and the steering tracks true, with the car going exactly where I want, but things have gotten busy. The drive plays out like a scene from the original Mad Max, when budget-limited director George Miller sped up the film for dramatic effect.

Modern sports cars are programmed to deliver maximum performance for the situation, so I’ve left the transmission in fully automatic mode. Most cars do not achieve their top speed in top gear because that takes the engine rpm out of the peak of the power band. I didn’t realize the Artura would shift to top gear when my foot was on the floor, seeking more speed, so in retrospect, I wish I’d shifted manually and left it in sixth gear rather than letting it upshift to seventh.

Hammering down the straight, the Artura pulled quickly from 172 mph to 199 mph on the speedometer. And stayed there. Thanks to what felt like time dilation in my situation, the digital display seemed to sit maddeningly near 200 mph for minutes. Finally, “199” flickered to “200.”

The speedometer stayed at 200 mph all the way through the finish line. That seemed sufficient to ensure the official results captured that outcome.

Coasting down from 200 mph, previously ludicrous speeds now seem pedestrian. Organizers have warned us to make extra effort to shed speed so that when we approach the parking lot at the end of the run, we are at a speed that is actually safe rather than one that seems safe to a driver who is pumped up on adrenaline and whose perception is distorted by having recently hit two tons.

I get to the parking lot, where attendants point me to my parking slot. Heading over to the official timing and scoring display, I get crushing results from the GPS: 194.98 mph. Not two tons. Dammit. Apparently, the Artura’s speedometer is slightly optimistic. By 2.5 percent, it looks like.

But the in-car GoPro captured the dashboard display, which shows “200.” I have photographic proof of having achieved that speed, even if it comes with a really big asterisk.

Weeks later, organizers whimsically sent me an official-looking speeding ticket from the Blaine County Sheriff’s Office, citing me for my official top speed of 194.98 mph. It is the first time I’ve ever wished for a bigger number on a speeding ticket.

Tesla’s Cybertruck isn’t even available to the public yet, but concept art for a Cybertruck cop-car made its appearance in Las Vegas on Wednesday. During a presentation by Oracle co-founder Larry Ellison at the data service giant’s CloudWork conference, a massive screen showed off the EV’s recognizable, angular design beneath red and blue emergency lights, as well as a bull bar and multiple Oracle logos.

But as Inside EVs noted on September 21, the rendering features misplaced bumper lights and rear wheels, while also missing the vehicle’s single, massive windshield wiper. Although this could indicate the project is early on in its development, Ellison promised its imminent debut.

“Our next generation police car is coming out very soon,” Ellison said to audible audience murmurs. “It’s my favorite police car. It’s my favorite car, actually. It’s Elon’s favorite car.” 

[Related: What TikTok’s deal with Oracle could mean for user security.]

“Among other things, it’s very safe, very fast, it’s got a stainless steel body, and we don’t have to add a screen or cameras to it because we can actually use their existing cameras and existing screen to put our application on it,” Ellison continued.

Both Oracle and Tesla already work alongside law enforcement, providing cloud support software and electric vehicles, respectively, for forces in Wisconsin, California, and elsewhere. Ellison has also called Musk a “close friend” in the past, and previously sat on Tesla’s board of directors. According to Ellison’s presentation, the first Oracle-integrated police cars already include voice-activated, retrofitted third-party “Tesla-like” screens, but the company plans to leverage the Cybertruck’s existing camera systems and monitors. 

First unveiled in 2019 and promised to arrive in 2021, Tesla has since delayed the Cybertruck multiple times while also increasing its estimated price tag. At last check, production and delivery were slated to begin by the end of 2023, although that deadline now appears dubious. During the EV’s debut event, Tesla vehicle designer Franz von Holzhausen threw metal balls at a prototype Cybertruck to demonstrate its “Armor Glass” windows, causing the driver side windows to shatter.

“The ball didn’t make it through,” Musk joked at the time.

Other automakers are interested in this kind of mega-casting technique, in which a single large part is manufactured in a big press.

From the start, Tesla has eschewed traditional manufacturing, design, and sales models, and the company’s latest move could involve revolutionizing the production of its snub-nosed EVs, as a recent Reuters story reports. Previously, the EV giant proved it could reduce costs and parts by casting the front end and back end of its Model Y as whole sections instead of assembled parts, which Tesla calls “gigacasting,” on brand with its 10-million-square-foot Gigafactory in Austin, Texas.  

Tesla’s next step could be die-casting nearly the entire underbody as a singular piece versus the 400 parts it generally takes to assemble the same section of a conventional car, according to Reuters. As that news organization puts it, if Tesla manages to die cast the whole piece successfully, it would “further disrupt the way cars are designed and manufactured.” 

How does a house-sized die-casting machine work, and can it make that much difference in the industry? Read on to learn more.

How the casting process works

Tesla already uses what it calls a gigapress, an aluminum die-casting machine at its factories in the US, Germany, and China. In very basic terms, molten metal is injected into a mold (the “die”), then cooled, ejected, and trimmed. The die-casting process was originally conceived in the mid-1800s, and automotive companies have used this manufacturing method for decades.

In June, Reuters stated that Tesla also developed an aluminum alloy that allows it to “skip the heat treating traditionally used to increase the strength of the cast part.” That detail might trigger alarm bells, considering the tendency for Tesla vehicles to show signs of lackluster quality control when it comes to fit and finish. However, Ed Kim, president and chief analyst for research firm AutoPacific, believes Tesla approaches its body assembly differently.  

“The areas where Tesla has had issues in terms of quality are typically related to squeaks and rattles and panel fit,” Kim says. “But it has done a great job on innovative manufacturing techniques.”

The entire industry has taken notice, with Toyota, Hyundai, Volvo, and others pledging to explore a similar manufacturing avenue (and calling it “hypercasting” and “megacasting” instead). Large-scale die casting is a tricky process, and some critics point to the fact that a single flaw can compromise the whole piece. On the other hand, using a gigapress (or “megapress” as other automakers may call it) can help preserve profit margins by streamlining the process. 

The cost conundrum

Price is certainly a large factor, and Tesla says it cut related costs by 40 percent, according to Reuters, by using a gigapress on its most popular vehicle, the Model Y. That appeals to other automakers, like Toyota. 

“It doesn’t surprise me that Toyota has taken an interest in [gigacasting], because I’ve always thought of Toyota as a manufacturing company above all else,” Kim says. “Historically, Toyota really set the bar on smart, efficient manufacturing and figuring out ways to take cost out of the process without sacrificing quality.” 

Toyota executives may be kicking themselves for not adopting more large-scale die-casting first, he continues. The process is still very new, however, with much to prove, although automakers will certainly be watching. American companies are especially vulnerable to cost and revenue challenges, and the United Auto Workers’ current strike is creating a new flux in future plans; they may look at what Tesla’s doing and decide to go that route, but the relationship with the factories and those who work there adds a layer of complexity.  

Tesla has promised that a new $25,000 entry-level model is on the horizon, and that will require creative cost-cutting measures across the board, including perhaps the gigapress. 

“It’s so different from the assembly line model,” Kim says. “Given the rumored failures on the Cybertruck, the brand is particularly sensitive to manufacturing costs for its upcoming entry-level car and it needs to keep costs down.” 

The EV company’s ability to pull off using the gigapress on its Model Y contributed to its ability to slash prices, putting the competition on the defensive. Die-casting in this manner is technically difficult to execute and changes are very costly, which is why not everyone is jumping in right away, Kim says. Reducing manufacturing costs in a repeatable manner is the holy grail, he says, and automakers are all keeping an eye on this development. 

“Based on the success of the Model Y, Tesla can potentially pull it off,” he admitted.

Honda’s newest electric scooter, called the Motocompacto, looks like a roving suitcase. Announced this week, the Motocampacto is designed to be foldable and lightweight, meaning that the handlebars and seat can be tucked into the suitcase-shaped main body of the vehicle. The idea is that this should make it easy to transport and easy to store. According to Honda, it should be able to reach “a maximum speed of 15 mph and [has a] zero-emissions range of up to 12 miles.” 

Additionally, Motocompacto “can be fully charged in just 3.5 hours in both the folded and ready-to-ride configuration using a common 110 v outlet.” At a price tag of $995, it will be available for purchase later this year. 

The Motocompacto is an updated, electric take on an early ’80s Honda design called the Motocompo. Similarly, the Motocompo was also a collapsible scooter, but it looked more like a handyman’s duffle bag in its condensed form. The intent was that it could fit into the cargo space of the Honda City kei car, presumably so it could serve as a final mile solution, where it carried people to their destination beyond where they were allowed to park a car. 

[Related: Electric cars are better for the environment, no matter the power source]

While Motocompacto should be able to carry out the same jobs as the original model, it comes with more modern conveniences. “Motocompacto is perfect for getting around cityscapes and college campuses. It was designed with rider comfort and convenience in mind with a cushy seat, secure grip foot pegs, on-board storage, a digital speedometer, a charge gauge and a comfortable carry handle,” Honda said in the press release. “A clever phone app enables riders to adjust their personal settings, including lighting and ride modes, via Bluetooth.”

Its wheels and frames are made with heat-treated aluminum, and it has bright LED headlight and taillight, side reflectors, and “a welded steel lock loop on the kickstand that is compatible with most bike locks.” It weighs around 41 lbs, comparable with how heavy a carry-on suitcase typically is. 

[Related: BMW’s electric scooter will hit 75 mph and has motorcycle vibes]

The vehicle is part of Honda’s larger goal to release more electric models of its fleet by 2030, and to sell only electric or fuel cell models by 2040. It joins other major carmakers around the world, like GM, Ford, Hyundai, Volvo, and more, which are all committing to lowering global carbon emissions by offering more new EVs as options for consumers. The Motocompacto is set to be sold in conjunction with the company’s newest lineup of all-electric SUVs, Jane Nakagawa, vice president of the R&D Business Unit at American Honda Motor Co., said in a statement. “Motocompacto supports our goal of carbon neutrality by helping customers with end-to-end zero-emissions transport.”

A tiny racing car completely designed and driven by university students has set a new Guinness World Record for fastest acceleration in an electric vehicle. Earlier this month, the miniscule speedster rocketed from 0 to 100 km/h (roughly 62 mph) in just 0.956 seconds, traveling a total distance of 12.3 meters (40.35 feet). The new benchmark time is over a third faster than the previous record set almost exactly a year ago in September 2022 by a team of student designers at Germany’s University of Stuttgart.

Months of design work and testing took place thanks to the members of Academic Motorsports Club Zurich (AMZ), a student organization that has built a new race car every year since its founding in 2006. After three vehicles running on internal-combustion engines, AMZ switched over to completely electric designs in 2010. They’ve adhered to the eco-friendly alternative ever since.

“Working on the project in addition to my studies was very intense. But even so, it was a lot of fun working with other students to continually produce new solutions and put into practice what we learned in class,” Yann Bernard, AMZ’s head of motor, said in the team’s announcement on September 12. “And, of course, it is an absolutely unique experience to be involved in a world record.”

[Related: How Formula E race cars are guiding Jaguar’s EV future.]

The AMZ team’s newest iteration, dubbed mythen [sic], were entirely designed and optimized by the university students. Among its many impressive attributes, mythen boasts a carbon and aluminum frame that keeps the vehicle’s entire weight at just under 309 pounds. Specialized four-wheel hub motors alongside a novel powertrain combined to boost the race car via around 326 hp.

From an aerodynamic standpoint, mythen is so fast and lightweight that it even needed some backup additions to keep it on the race track. Two wings—one in both the front and rear—helped push the car towards the ground. Students meanwhile also designed and installed a “kind of vacuum cleaner” to help hold the vehicle on the road via suction, according to the team’s announcement.

“[P]ower isn’t the only thing that matters when it comes to setting an acceleration record,” said Dario Messerli, AMZ’s head of aerodynamics in a statement, “Effectively transferring that power to the ground is also key.”

Before this month, AMZ set the world acceleration record for electric cars twice already—once in 2014, and two years’ later in 2016. Given how quickly these cars seem to run, as well as how frequently they are redesigned and tested, it stands to reason that the team will probably be fending off competitors in the very near future.

Great installation options and above-average weather resistance make you feel like speeding less didn’t mean compromising.

With backup cameras being mandated in newly made U.S. vehicles starting in 2018, it is inevitable that you’ll find yourself in a car with one, if you haven’t already. Whether you’ve been an Uber passenger or used a backup camera in your latest rental car, your immediate reaction may have been to wonder if there is an easy way to retrofit your car with this newly ubiquitous feature. We were curious, too, and spent some time researching what the market has to offer. The good news is that there are a wide number of types, brands, and price levels for the best aftermarket car accessories, and from these, we’ve selected our top picks for the best backup cameras.

How we chose the best backup cameras

Backup cameras are a strange breed, in that what makes a good backup camera is completely different from what makes a good digital camera (or even a good dash cam). While the latter will be all about PPI and the other hallmarks of high-quality imagery, including lenses and the like, the best backup cameras focus on functionality. Don’t get us wrong, we care about high-quality imagery from our backup cameras, too, but in selecting the best backup cameras we reoriented from the basics and sought out the special qualities that make backup cameras function so well. We combined this research with critical reviews, peer suggestions, and user impressions to narrow down our choices to five use cases.

The best backup cameras: Reviews & Recommendations

The following recommendations and write-ups come after some careful review of the aftermarket backup camera market and combine the top picks of today with specific customer needs. As a result, you’re going to see a mixture of great general-use backup cameras and products that only support a particular car model. In this way, we’ve covered at least one product that will work for just about anyone.

Best overall: AUTO-VOX T2

AUTO-VOX

SEE IT

Why it made the cut: The AUTO-VOX T2 has the best features a backup camera can provide, all wrapped up in a simpler design.

Specs

  • Connection: Wired
  • Power source: Reverse brake light
  • Angle of view: 170 degrees

Pros

  • Full-color instruction manual
  • Easiest wired install
  • Complete kit works with most cars
  • Dust- and water-resistant camera

Cons

  • Only works when in reverse

The incredible specs of AUTO-VOX’s T2 make it the go-to for a simple backup camera experience. The camera, which sits atop your license plate, has a wide view of 170 degrees, automatically adjusts for brightness, is rated IP68 to protect from dust and water damage, and provides vivid night vision colors. These top-of-the-line qualities carry the T2 heavily, but there’s a bit more going on here.

The T2’s internal display also makes it the best rear-view mirror backup camera. Instead of using a separate view panel, the T2 gives you a new rear-view mirror with a special electronic surface. When you engage in the reverse gear, a portion of your mirror turns into a camera display so you can check the digital view and the real mirror view side-by-side. When you shift out of reverse, the panel disappears and you have a full rear-view mirror again.

While the wired connection might put you off as there is a bit of installation work (if that’s you, check out the BOSCAM SunGo Pro, our best wireless backup camera and a solid “green” pick) you should also understand that the wiring on the T2 is in a league of its own. For one, the wires are limited by relying heavily on your reverse brake light’s power. You won’t even need a wire down to your cigarette lighter up front with you. This one-wire design keeps a lot of the trouble away from you and into the rear of your car.

Additionally, the provided kit comes with a lot of gear, including all of the wire casing and clamps you’ll need, plus different bracket adapters to make the T2 compatible with over a dozen of the leading car manufacturers. From Toyota and Nissan to Acura and Cadillac, the T2 will likely work with your car. Between the detailed instruction manual that includes full-color images and the plentiful YouTube videos showing the installation, you’ll be able to handle it.

Best for Garmin products: Garmin BC40

Garmin

SEE IT

Why it made the cut: The Garmin BC40 wirelessly delivers a clear backup view with easy installation.

Specs

  • Connection: Wireless
  • Power source: Two AA batteries
  • Angle of view: 160 degrees

Pros

  • Wireless connection makes for easy installation
  • IPx7 waterproof rating
  • Offers simple voice command control

Cons

  • Requires a separately-sold Garmin Navigator unit to function

The Garmin BC40 is one of the best wireless backup cameras designed for use with Garmin navigator systems, delivering a 160-degree rear view of your vehicle with very little installation effort. The camera unit clips into an included license plate mount and powers on using two separately-sold AA batteries, after which it pairs easily with any compatible Garmin navigation device that’s brought within a 5-foot radius of the camera. After this easy setup process, the camera stays paired at ranges of up to 25 feet, powering on anytime the GPS device is activated and turning off automatically when forward motion is detected. The BC40 also allows users to program custom voice commands for hands-free activation and deactivation, giving it an edge in safety over touch-only backup camera devices.

Best for RV: Furrion Vision S FOS07TAPM

Furrion

SEE IT

Why it made the cut: The Furrion Vision S is pre-made to attach to over a dozen popular brands of RV and trailer, provides four cameras for complete coverage, and assembles completely wirelessly.

Specs

  • Connection: Wireless
  • Power source: Wired to marker lights
  • Angle of view: 120 degrees x 4

Pros

  • Four-camera, complete vision design
  • Ready-to-attach mounting
  • IP65 dust- and water-resistant
  • Motion sensor tech with microphones

Cons

  • Expensive

For those of you into mobile homes, RVs, campers, and trailers of immense length, even the thought of stopping for gas can send you into a rage of panic. One spouse at the wheel and the other outside the vehicle aggressively signing to come back, stop, or turn—the whole event is quite stressful.

That’s why you need something more intense for RVs than a standard backup cam … you need four of them! With the Furrion Vision S FOS07TAPM, you’re getting exactly that: four high-quality cameras with night vision and excellent weather resistance that beam images directly to a 7-inch anti-glare monitor. Now you can know your vehicle’s rear-view, as well as make sure your left flank, doesn’t clip that branch as you reverse out of trouble.

The thing that sets Furrion products above the rest is how many more big brands come Furrion-ready compared to others in the market. This includes Keystone, Starcraft, East To West, and Heartland. In other words, many of these models already have mounting brackets installed, at least for the rear camera. Plus, the entire thing is wireless, meaning no drilling through your vehicle to install your RV backup camera.

With all that you’re getting, it should come as no surprise that this is the most expensive product on our list at over a grand, but remember that you’re getting four times the cameras and equipment, so the price largely balances out in the end.

Best green: BOSCAM SunGo Pro

BOSCAM

SEE IT

Why it made the cut: Finally, we have a solar-powered camera option that really works.

Specs

  • Connection: Wireless
  • Power source: Solar exterior, cigarette lighter interior
  • Angle of view: 170 degrees

Pros

  • Speedy install
  • Low-light night display
  • IP68 dust- and water-resistant
  • Customer service winner

Cons

  • License plate bracket tight

If you’re looking for the most sustainable backup cam, check out the BOSCAM SunGo Pro, which features a solar-powered camera and a low-light night display. It’s all wrapped up in a nature-resistant IP68 shell, as well, so you freely explore nature while putting a little less stress on the environment.

The BOSCAM SunGo Pro is able to be charged from your car’s exterior using a single-crystal silicon solar panel. Also known as monocrystalline solar cells, single-crystal solar panels are the most commonly used and convert sunlight more efficiently than polycrystalline designs. In a worst-case scenario, such as having your car parked under a tree for a week, an alternative USB charge port is available.

One of the things to note about the BOSCAM SunGo Pro is that the bracket mount for the camera, the part that goes around your license plate, is rather tight. Basically, there is a sense that it almost won’t fit, but it does. Don’t let this turn you off of a great product, though, and know that BOSCAM is there for you to help.

Speaking of help, when researching products online, the write-ups often bring up a lot of customer problems. What is much rarer is an honest discussion of solutions that amounts to more than “I fixed it myself.” One of the very promising things about BOSCAM as a company is how often you hear that a customer complaint led to real dialogue and reasonable help from the company.

Best for Jeep Wrangler: EWAY Backup Rear-View Spare Tire Mount

EWAY

SEE IT

Why it made the cut: The EWAY modifies the traditional rectangular license plate mount and circle-fies it for the iconic Jeep Wrangler rear spare tire.

Specs

  • Connection: Wired (RCA)
  • Power source: Reverse brake light
  • Angle of view: 150 degrees

Pros

  • Made for Jeep Wrangler specifically
  • Anti-fog lens
  • Low impact installation
  • Rearview-mirror display

Cons

  • Included instructions lacking

The Jeep Wrangler’s iconic hatchback look, with the large spare tire affixed to the back, creates a sense of style and adventure for the driver but also an immediate problem: Where should I put a backup camera on my Jeep Wrangler? The truth is, the options are somewhat more limited for Wrangler drivers, but the EWAY camera is here to fix that problem by mounting directly behind that spare tire and peering beyond it.

Of course, it takes more than just proper, simple mounting to make something worthy of the title of best backup camera for a Jeep Wrangler. What gives? For one, the camera is in crisp HD, provides a full 150-degree angle of view, and sends the view to a 4.3-inch display on a modified rear-view mirror. It’s also using an anti-fog lens and pulling in an official IP68 rating, making it dust- and water-resistant. Essentially, the EWAY gets carried by stats, numbers, and overall value for the cost.

As far as wired backup camera installations go, the EWAY is relatively low impact. For example, the guideline view can be toggled without cutting, and you are provided with ample cable length. What is difficult is dealing with the instruction manual, which can be a real head-scratcher. Definitely supplement the instructions with a very visual YouTube tutorial.

Best budget: LeeKooLuu LK3

LeeKooLuu

SEE IT

Why it made the cut: With the LeeKooLuu LK3 you get a 1080p, 149-degree, IP69 camera quality for under $50.

Specs

  • Connectivity: Wired
  • Power source: Reverse brake light OR cigarette lighter
  • Angle of view: 149 degrees

Pros

  • Great installation options
  • Above-average weather resistance
  • Strangely superior camera

Cons

  • Unusual angle of view

The LeeKooLuu LK3 is your super-affordable go-to if you’ve gotten used to backup cameras and want quality, but don’t want to spend extra for advanced features when upgrading your old car. Instead, what you’re getting with the LK3 is one of the best backup cameras with a relatively simple system.

Two qualities to immediately look at when assessing the LK3’s camera are picture quality and angle of view. At 1080p, you’re getting a really high-quality backup camera in a sub-$50 shell, which is nothing to sneer at. However, this is where we need to remind you of the more important factor: angle of view. And, wow, the LK3 sports an unusual 149-degree angle of view. If you’ve used a newer car’s built-in 150-degree angle of view and gotten really used to it, this will probably feel just slightly off.

Another unusual feature of the LK3, though this time in a positive way, is the IP rating. IP69 is unusually high for a backup camera, with most peaking at IP68. So, what does an extra numeral mean? Well, for the typical backup camera user, not much. This basically just means that the LK3 can spend extra time underwater, a situation that would be so catastrophic for you that the livelihood of your LK3 would be the least of your worries. At the very least, you can rest assured that the LK3 will survive your next torrential downpour.

Things to consider before buying the best backup cameras

Since a backup camera is going to be installed on your car in some place, oftentimes just behind the license plate, there are a lot of different logistical issues to consider than whether it feels comfortable in your hand like a traditional camera. You’ll also be viewing the typical fish-eye lens in a completely different light when you realize how important angle of view becomes to a backup camera’s functionality. Here’s our in-depth guide for each quality:

Power source

Expect quite a few different power sources for backup cameras. These range from connecting to your rear brake lights to being solar-powered. And that’s just for the camera part! Remember that the internal viewing unit will also need a power source. Again, there’s quite a bit of variation here, from cigarette lighter plug-ins to wires that sneak under your dash. We’ll detail our top picks here, but if you venture out to make your own choice, do the extra time to research this thoroughly so you know what you’re getting into.

Wired vs. wireless

The debate over whether to get a wired or wireless backup camera is another subjective matter. While wireless backup cameras remove the hassle of wires and are just about the only way to go for trailers and exceptionally long vehicles, they do have the potential to introduce more lag into your system. If we lived in a world where people solely relied on backup cameras for backing up, that would be quite dangerous. The reality is, though, that backup cameras are a single tool in a multi-step process of backing up.

If you prefer an essentially lagless wired backup camera, be mindful that the wire will need to connect the camera (on the outside of your vehicle) to the camera inside your vehicle. This might seem like a hassle, but it can be worth it for a quality backup camera, such as our top pick, the AUTO-VOX T2, which also happens to have a streamlined wire system. If you do get a wired model, be sure to check out the instructions thoroughly before attempting to install it to avoid damaging your vehicle.

Angle of view

In this list, you’ll see HD, 1080p, and all other kinds of assorted camera qualities. Remember, though, that these will only help you so much. You aren’t shopping for beginner travel cameras to come with you on vacation; you’re looking for the best backup camera. Instead, the main measure of quality here will be the angle of view.

A high angle of view will allow you to see more in one picture than you could by looking through a single mirror and will greatly reduce the overall chances of danger to your vehicle while backing up. Expect to see values between 150 to 170 degrees for angle of view in high-quality backup cameras.

FAQs

Q: How much does a backup camera cost?

A backup camera costs between $50 for a simple design for the standard sedan to over $1,000 for a multi-camera unit design for a lengthy truck/RV. Standard designs with all of the best backup camera features will typically cost between $120 and $200. Remember that the manufacturer is delivering not only a camera but also the wiring (or wireless connection tools), mount, internal display, and other components to help with installation. Backup cameras are multi-part devices and are priced accordingly.

Q: What is a good resolution for a backup camera?

A good resolution for a backup camera is whatever you can see clearly. That answer is a bit cheeky, but there’s something to it. Typically, you’ll only be viewing what your backup camera captures through a small monitor; some made small enough to fit in a portion of a rearview mirror, so resolution isn’t as important as when selecting a TV. The result is that resolution isn’t as important for backup cameras as it is for other cameras. In other words, you don’t need an ultra-high-definition camera just to look at the image through a 4-inch screen. Instead, prioritize a quality angle of view so you can obtain the most information possible.

Q: How to install a backup camera?

To install a backup camera, you must first determine what type of camera you are buying—wireless and wired backup cameras install differently. Wireless backup cameras are typically simpler and follow specified mounting instructions given by the manufacturer. For wired backup cameras, however, you’ll need to run a wire from the outside of your vehicle (where the camera is located) to the inside of your vehicle for the monitor. This can take some mechanical know-how, a good instruction manual, or a video tutorial. Where the instructions are noted as being unclear, I’ve included links to quality YouTube tutorials in the writeups above.

Final thoughts on the best backup cameras

Getting the best backup cameras on your slightly older car does not need to be challenging or take an overly thorough amount of analysis. It is understandable to have some fear in regards to installing a product like this, especially with wired models, but offered with quality instruction manuals, online video tutorials, and even wireless models, backup cameras are indeed for everyone. Lastly, our picks for the top backup cameras, including the fantastic budget option from LeeKooLuu, will suit your needs perfectly well, except in some special fringe cases.

Today, Tesla is the industry leader—the automaker with the most EV sales. An updated Model 3 is finally on the horizon, and we’re hoping the company will address some of its quality and finish issues. What we’re hearing is that they will use more luxurious materials in the cabin, an updated dash, and more sound-deadening features like acoustic glass, to start.

But Tesla isn’t the only game in town. There’s also the Aston Martin Lagonda EV, Cadillac’s fully-customizable Celestiq, the Rolls-Royce Spectre, and the upcoming all-electric Chevrolet Corvette. And Automobili Pininfarina’s PURA Vision design concept is breathtakingly good, with a glass dome and French door-like openings that create a cavernous and comfortable way for passengers to enter. These cars are generally for the few and elite, however, and while they’ll move the industry in their own ways, it’s the mass-market EVs that are important for the rest of us.

Let’s take a look at what’s on the horizon for next year.

Volvo EX30

Expected to make its debut later this year, Volvo’s smallest-ever SUV, the EX30, is all-electric. The EX30 will start at $36,145, which is significantly less than its EV predecessors, the C40 Recharge and XC40 Recharge. It’s also smaller than the other two but can match their towing capacity—up to 2,000 pounds. 

Equipped with a 268-horsepower motor, the base model EX30 comes with rear-wheel-drive and will be good for an estimated range of 275 miles. For a higher (to be determined) price, the EX30 will also be available as an 422-horsepower all-wheel-drive model. In either case, Volvo says it will charge up from 10 percent to 80 percent in about 26 minutes on a DC fast charger.

Available in a decidedly non-Volvo color called “moss yellow” along with a handful of other hues, the EX30 will feature renewable and recyclable materials inside. Taking its place in the front of the cabin, a 12.3-inch tablet serves as the infotainment, climate, and vehicle control center, and Calm View reduces the amount of information on display. 

Jeep Recon

We’ve seen Jeep’s future and even took a spin in the 650-horsepower Magneto, Jeep’s Wrangler EV concept. It’s not quite ready for production, yet; after all, the Wrangler is a beloved nameplate and a switch this big requires extra attention to all of the details. Jeep has seen massive success with its hybrid Wrangler 4xe and will keep the momentum going on that model. 

Meanwhile, the brand will start production of the all-electric Recon next year. Jeep has revealed only scant information so far; what we can see is that there will be seating for five and it’ll sport fun Wrangler-like features like removable doors and a power-folding rooftop. This upcoming midsize SUV will be trail-rated, and we expect it to include some of the same goodies as in the Wrangler, like the new trail maps app that debuted this year. No final word on pricing yet, but it’s fair to guess that it will probably start at about $50,000. 

Hyundai Kona Electric

The outgoing Kona is adorable, like a pet Corgi. For 2024, Hyundai sharpened the small SUV’s edges, giving it a leaner, more modern look, and the vehicle is longer and wider than before. Estimated to have a range of between 197 and 260 miles (depending on the battery pack) and powered by a single motor making 133-horsepower, the base model is destined to thrive in city environments. Those wishing for more oomph will want to take a look at the 201-horsepower option. Starting at an estimated $35,000, the Kona EV is in the sweet spot of pricing. 

We’re truly excited about the entire Hyundai EV lineup, which also includes the Ioniq 5 and Ioniq 6. All three models share a pixel theme and a futuristic feel, and it will be interesting to see which of these (or all) advance to the next model year and beyond. 

Mercedes-Benz CLA EV concept

Typically, the words “Mercedes-Benz” and “affordable” pair together as well as fine red wine and Tostitos. The German powerhouse is (kind of) changing that with the upcoming CLA EV concept car. Launching an entry-level EV class will benefit Mercedes-Benz by proving its EV mettle and bringing more fans to the brand, giving them the opportunity to upgrade over time; that’s a smart strategy to attract younger buyers. 

Mercedes-Benz says its new four-door coupe will have a range of 466 miles. It’s worth noting that number is higher than the Tesla Model S, which offers 405 miles, and the only other car on the market right now with more than that is the Lucid Air, at over 500 miles. However, the Air sits solidly in the six-figure price zone, while the CLA EV is predicted to start at about $60,000. That may not sound cheap, but on the Mercedes-Benz scale, it’s extraordinary. It’s unclear how soon the CLA EV will be available, but it looks like it’s going to be next year. 

Honda Prologue, the Chevrolet Blazer EV, and more

Strange stablemates as they may seem, there is a symbiotic relationship between Honda and Chevrolet that will bring us a pair of EVs next year. Honda teamed up with Chevy to use Ultium battery packs (used on vehicles like the GMC Hummer EV and Cadillac Lyriq) on the Prologue, which is a midsize SUV expected to launch in 2024 with a price tag starting in the mid-$40,000s. The Prologue will be offered with a single or dual-motor configuration. We expect Honda to match the range of the ZDX built by its luxury branch, Acura; the ZDX is also powered by the Ultum platform and can go for at least 315 miles. 

On the other side, the Chevrolet Blazer EV will look different from the Prologue and seems to come with a higher price tag, starting in the mid-$50,000s. We can’t wait to get our hands on the SS trim, with an impressive setup that generates 557 horsepower. 

And wait, there’s more to come. We’re looking forward to hearing more about Fisker’s sub-$40,000 Ocean model and Kia’s new upcoming EV9; the EV6 is one of our favorite EVs on the market currently for smooth driving and a terrific cabin configuration. 

Last, but certainly not least, Ford recently announced the 2024 Mustang Mach-E Rally model designed for off-roading, and we can’t wait to get our hands on it. Expected to start at $65,000, the Mach-E Rally boasts two electric motors making 480 horsepower and 650 pound-feet of torque.

Mozilla Foundation's review of 25 major automakers' privacy policies is a disconcerting look into vehicle tech security.

A comprehensive data privacy assessment of 25 major automakers’ vehicle tech deems cars “the official worst category of products for privacy” that the Mozilla Foundation has ever reviewed. For a bit of context here, every car company analyzed by Mozilla’s security experts failed crucial benchmark safeguards, compared to 63 percent of mental health apps they reviewed this year (which often come with their own serious security risks).

“While we worried that our doorbells and watches that connect to the internet might be spying on us, car brands quietly entered the data business by turning their vehicles into powerful data-gobbling machines,” Mozilla’s researchers explained in their findings announcement earlier this week. Because of this, they warn, vehicles’ “brag-worthy bells and whistles” now possess “an unmatched power to watch, listen, and collect information about what you do and where you go in your car.”

The companies boasting abysmal ratings include pretty much any automaker you can imagine—including Ford, Subaru, Jeep, BMW, Honda, Acura, Chevy, and Nissan, among others—with Tesla ranked dead last on the list. According to the experts, nearly 85 percent of surveyed automakers “share” car owners’ data to data brokers and other businesses. In total,19 of the 25 companies actually sell your personal data to third-parties, while over 55 percent of the carmakers’ Privacy Policies allow them to share your information to government and law enforcement authorities. Such data deliveries can be facilitated via a simple “request” instead of a legal warrant or court order.

[Related: Mental wellness apps are basically the Wild West of therapy.]

If all that weren’t enough, an additional creepy layer further worsens matters. According to Mozilla, at least two companies—Nissan and Kia—include Privacy Policy data categories explicitly labeled “sexual activity” and “sex life.” Exactly what kind of data this entails isn’t clear, but new cars often come equipped with microphones and cameras. Even if this data is somehow anonymized and aggregated, chances are those in the market for a new vehicle might want to take a closer look.

In an email provided to PopSci, a Kia spokesperson explains, “The privacy of consumers is important to Kia… Whether certain information is collected by us depends on the context in which a consumer interacts with us,” before clarifying that, “Kia does not and has never collected ‘sex life or sexual orientation’ information from vehicles or consumers in the context of providing the Kia Connect Services.”

Per Kia’s privacy policy page, “sex and gender information,” as well as “health, sex life or sexual orientation information” may be collected.

A spokesperson for Nissan tells PopSci the company complies “with all applicable laws and provide[s] the utmost transparency,” while stating “Nissan does not knowingly collect or disclose consumer information on sexual activity or sexual orientation.”

“Our privacy policy is written as broadly as possible to comply with federal and state laws, as well as to provide consumers and employees a full picture of data privacy at Nissan,” the spokesperson continues. “Some state laws require us to account for inadvertent data collection or information that could be inferred from other data, such as geolocation. For employees, some voluntarily disclose information such as sexual orientation, but it is not required and we do not disclose it without consent.”

What’s particularly infuriating these findings is that, as Mozilla explains, there simply isn’t much everyday car owners can do about it. Each individualized review of the 25 carmakers includes a section entitled “Tips to protect yourself,” which includes suggestions such as to avoid using a car’s app and limiting its permissions on your phone.

“But compared to all the data collection you can’t control, these steps feel like tiny drops in a massive bucket,” concedes Mozilla researchers. In response, the Mozilla Foundation has launched a petition asking companies to overhaul their massive, apparently unparalleled data collection programs.

Update 9/07/23 1:26 PM: This article now includes statements from both Kia and Nissan.

From clay cars to VR: How GM is designing an electric fleet at top speed https://www.popsci.com/technology/gm-brightdrop-electric-delivery-vehicle-vr/ Tue, 05 Sep 2023 19:10:50 +0000 https://www.popsci.com/?p=568123

While creating its electric delivery vehicles, BrightDrop turned to virtual reality and even a large wooden model.

Historically, the process of designing vehicles could take years. Starting with initial sketches and ending with the final product, the timeline has included making life-size clay exterior models, doing interior modeling, conducting tests, and more.

During the lockdowns of the global pandemic beginning in 2020, General Motors teams found themselves in a new quandary: moving forward on projects while working remotely, and without physical representation of the vehicles in progress to touch and see. GM had dipped a big toe into using virtual reality to accelerate the development process for the GMC Hummer EV pickup, which launched in October 2020. That gave the team a head start on the Zevo 600, an all-electric delivery van.

Developed by BrightDrop, GM’s breakout business dedicated to electrifying and improving the delivery process, the Zevo 600 went from sketch to launch in January 2021 in a lightning-quick 20 months. A large part of that impressive timeline is due to the immersive technology tools that the team used. The modular Ultium battery platform and virtual development process used for the Hummer EV greased the wheels. 

Here are the details on the virtual tools that helped build the electric delivery van.

What does it mean to design a vehicle this way?

BrightDrop says it considers itself a software company first and a vehicle company second, and there’s no question it’s pushing the envelope for GM. Bryan Styles, the head of GM’s immersive technology unit, sees the impetus behind this focus as coming from the industry’s increasing speed to market.

“The market continues to move very quickly, and we’re trying to increase the speed while still maintaining a high level of quality and safety at this pace,” Styles tells PopSci. “Immersive technology applies to design space up front, but also to engineering, manufacturing, and even the marketing space to advertise and interface with our customers.”

Working remotely through technology and virtual reality beats holding multiple in-person meetings and waiting for decisions, which can be very challenging as it relates to time constraints. 

“GM’s Advanced Design team brought an enormous amount of insight and technical knowledge to the project, including our insights-driven approach and how we leveraged GM’s immersive tech capabilities,” says Stuart Norris, GM Design Vice President, GM China and GM International, via email. “This enabled us to continue to collaboratively design the vehicle during the COVID-19 pandemic from our offices, dining rooms and bedrooms.”

The project that led to BrightDrop started with a study of urban mobility; the GM team found “a lot of pain points and pinch points,” says GM’s Wade Bryant. While the typical definition of mobility is related to moving people, Bryant and his team found that moving goods and products was an even bigger concern.

“Last-mile delivery,” as it’s often called, is the final stage of the delivery process, when the product moves from a transportation hub to the customer’s door. The potential for improving last-mile delivery is huge; Americans have become accustomed to ordering whatever strikes their fancy and expecting delivery the next day, and that trend doesn’t appear to be slowing down any time soon. In jam-packed cities, delivery is especially important.

“We traveled to cities like Shanghai, London, and Mumbai for research, and it became very apparent that deliveries were a big concern,” Bryant tells PopSci. “We thought there was probably a better design for delivery.”

Leave room for the sports drinks

Leveraging known elements helped GM build and launch the Zevo 600 quickly. As Motortrend reported, the steering wheel is shared with GM trucks like the Chevrolet Silverado, the shifter is from the GMC Hummer EV Pickup, the instrument cluster was lifted from Chevrolet Bolt, and the infotainment system is the same in the GMC Yukon. 

Designing a delivery van isn’t like building a passenger car, though. Bryant says they talked to delivery drivers, completed deliveries with the drivers, and learned how they work. One thing they discovered is that the Zevo 600 needed larger cup holders to accommodate the sports drink bottles that drivers seemed to favor. Understanding the habits and needs of the drivers as they get in and out of the truck 100 or 200 times a day helped GM through the virtual process. 

The team even built a simple wooden model to represent real-life scale. While immersed in virtual technology, the creators could step in and out of the wooden creation to get a real feel for vehicle entry and exit comfort, steering wheel placement, and other physical aspects. Since most of the team was working remotely for a few months early in the pandemic, they began using the VR tech early on and from home. As staff started trickling into the office in small groups, they used the technology both at home and in the office to collaborate during the design development process even though not everyone could be in the office together at once.

The Zevo 400 and 600 (each referring to the van’s cargo capacity in cubic feet) is the first delivery vehicle that BrightDrop developed and started delivering. So far, 500 Zevo 600s are in operation with FedEx across California and Canada. The first half of this year, the company has built more than 1,000 Zevo 600s and are delivering those to more customers, and production of the Zevo 400 is expected to begin later this year.

Roads? Where we're going, we don't need roads.

Maserati did something similar  

GM isn’t alone in its pursuit of fast, streamlined design; Maserati designed its all-new track-focused MCXtrema sports car on a computer in a mere eight weeks as part of the go-to-market process. As automakers get more comfortable building with these more modern tools, we’re likely to see models rolled out just as quickly in the near future. 

It may seem that recent college graduates with degrees in immersive technology would be the best hope for the future of virtual design and engineering. Styles sees a generational bridge, not a divide. 

“As folks are graduating from school, they’re more and more fluent in technology,” Styles says. “They’re already well versed in software. It’s interesting to see how that energy infuses the workforce, and amazing how the generations change the construct.” 

Where is vehicle design going next? Styles says it’s a matter not necessarily of if automakers are going to use artificial intelligence, but how they’re going to use it.

“Technology is something that we have to use in an intelligent way, and we’re having a lot of those discussions of how technology becomes a tool in the hand of the creator versus replacing the creator themselves.”

Two self-driving taxis blocked an ambulance on its way to a hospital, potentially contributing to the patient’s death, according to a San Francisco Fire Department report obtained by Forbes. The incident involving two Cruise vehicles occurred on August 14, just four days after state regulators approved 24/7 public availability of autonomous cab services in the city.

[Related: “Cruise’s self-driving taxis are causing chaos in San Francisco.”]

Emergency responders arrived around 10:45 PM at the scene of an accident involving a critically-wounded pedestrian, the report states. While there, however, the Cruise autonomous taxis occupied two lanes of a four-lane, one-way street, forcing a police vehicle in a separate lane to move to make space for the ambulance to leave. 

“The [patient] was packaged for transport with life threatening injuries, but we were unable to leave the scene initially due to the Cruise vehicles not moving,” reads a portion of the official report. “This delay, no matter how minimal, contributed to a poor [patient] outcome… The fact that Cruise autonomous vehicles continue to block ingress and egress to critical 911 is unacceptable.”

Cruise representatives dispute the SFFD report, instead claiming the fleet vehicles did not hamper medical treatment in any way. “The ambulance behind the [autonomous vehicle] had a clear path to pass the AV as other vehicles, including another ambulance, proceeded to do,” a Cruise spokesperson told PopSci. “As soon as the victim was loaded into the ambulance, the ambulance left the scene immediately and was never impeded from doing so by the AV.” In footage provided to The NY Times, EMS maneuvered around a Cruise vehicle roughly 90 seconds after loading the victim into the ambulance.

Public documents obtained by Forbes detail over 70 instances since April 2022 of autonomous vehicles allegedly obstructing a variety of emergency responses—including fires, and restoring electrical services. Despite months of pushback from many residents and city officials, California regulators approved the public usage of autonomous taxi services like Cruise and Waymo in San Francisco last month. Within days of the greenlight, however, the autonomous vehicles reportedly ran stop signs, produced lengthy traffic jams, and recklessly swerved to avoid pedestrians.

BMW’s electric scooter will hit 75 mph and has motorcycle vibes https://www.popsci.com/technology/bmw-ce-04-electric-scooter-review/ Mon, 04 Sep 2023 14:00:00 +0000 https://www.popsci.com/?p=566993

The CE 04's price tag starts at $11,795. BMW

The divide between the motorcycle and scooter communities has long been deep, as illustrated in the classic 1979 rock flick Quadrophenia, which depicted the strife between the scooter-riding mods and the motorcycling rockers.

Today, there probably aren’t any actual brawls, but you don’t see a lot of crossover between people who ride scooters and those who ride motorcycles. I’m evidence of that because after decades of motorcycling, BMW’s innovative CE 04 electric scooter is my first scooter ride. It was worth the wait to ride the 2023 model, after the bike debuted for the 2022 model year.

The transition is eased by the fact that the CE 04 looks more like a spaceship than a scooter. Think of it as your dainty beach rental scooter augmented by Star Trek tech. Its size and bodywork fooled a good many motorcyclists into giving me the wave as they passed, an acknowledgement not generally extended to pilots of mere scooters.

There are other aspects of the CE 04 that make it much more than a Bermudan rental ride. There is the price tag, which starts at $11,795, as much as two or three times the cost of conventional scooters. And there is the curb weight, which at 509 lbs. is hefty as two or three beach scooter playthings.

To aid with that bulk the CE 04 has a reverse setting, making it easy to back out of the garage or parking space. The CE 04’s low-speed power metering means that twisting the grip only a little in such circumstances makes it easy to move the scooter microscopically. Seriously, it is possible to move the CE 04 a millimeter at a time.

The curb weight is 509 pounds, but a reverse setting helps with backing it up.

The CE 04’s top speed and range

Fortunately, on the road, it covers ground a bit faster. BMW says the CE 04 is not intended for highway travel, but curiosity got me onto the interstate with it to see what it would do, and when riding in sport mode the CE 04 easily zooms up to 70 mph and holds that speed effortlessly. BMW says the top speed is 75 mph, but I have reason to believe it can actually go a bit faster than that.

Of course, the faster and further you go, the more you’re going to burn through the battery’s storage. Much distance at that speed will have the rider testing the CE 04’s Level 2 240-volt charging speed to refill the depleted 8.5 kWh battery pack. The battery is mounted at the very bottom of the frame for a lower center of gravity. It uses air cooling through the attached finned heat sink on the pack’s underside, benefiting from airflow beneath the scooter.

BMW says it will take about an hour to reach an 80-percent state of charge from a completely dead battery pack using 240-volt charging, and more like 3.5 hours for regular 120-volt household current. The bike’s charging display said that charging from 40 percent state of charge to 100 percent using my ChargePoint Level 2 charger took two hours. The SAE charging port is just below the handlebars, on the right side.

The scooter's electronic guts.

Normal riding range is 80 miles, but low-speed cruising around town will do better than that and of course, those 70 mph highway blasts will leave you looking for a charging station much sooner. This distance is not so different from that of an internal combustion engine Harley-Davidson Sportster motorcycle with the tiny “peanut” gas tank. Riders have tolerated that for many years, though a Sportster did leave me walking to a gas station one time.

[Related: At $1,807, the Honda Navi is the perfect starter motorcycle for a beginner]

Another difference between the CE 04 and typical scooters is the absence of the noisy, smoking, two-stroke motor providing the accompanying soundtrack of a leaf blower everywhere you ride. While those scooters deliver more sound than fury, the CE 04’s 42-horsepower permanent magnet EMP 156 electric motor blasts the BMW to 60 mph in 9 seconds.

Riding in ECO mode extends the riding range while making the CE 04 feel sluggish. It also increases the regenerative braking when the rider releases the twist throttle. Rain mode has the opposite effect, providing less braking so the bike coasts more freely to avoid inadvertently breaking traction. I rode mainly in Road mode on dry pavement.

It does not cruise as silently as expected—there’s a pretty constant electric whine at all speeds. More surprisingly, there’s a pretty loud gear whine during steady-state neighborhood-speed riding.

BMW’s motorcycles have historically employed a driveshaft rather than the usual chain, but the CE 04 follows Harley’s example with the kind of belt drive as seen on those American cruising machines. The belt’s benefit is that, unlike a chain, it never needs to be lubricated or adjusted.

That belt spins a rear wheel that, as a solid black-painted 15-inch disc, looks like nothing so much as a stamped steel temporary spare wheel for a car even though it is actually lightweight cast aluminum.

Starting the CE04—it’s wireless

Riders start the CE 04 with a press of a button thanks to the wireless key fob that can remain safely zipped inside the rider’s protective jacket. Twist the grip and the machine scoots effortlessly away, leading me to squirt up to speed and slow down a few times to get a feel for the electric power delivery. Pretty cool.

Regeneration slows the CE 04, making it easy to start and stop using the throttle, but there are regular brakes there too, in case a squirrel darts out directly ahead. BMW has developed a two-wheeled equivalent to its iDrive infotainment input device, with a scrolling wheel on the left handlebar that riders can also press inward to click a menu selection. BMW has named this the Multicontroller.

[Related: Behind the wheel of Volkswagen’s reinvented classic: the electric ID.BUZZ]

The Multicontroller for the CE 04’s 10.25-inch color display screen is a clever solution to the challenge of operating a computer with gloved hands while riding. However, it takes practice to master the menu system, and I didn’t have enough saddle time to get comfortable trying to use it while in motion.

The compact electric motor and underslung battery pack leave space beneath the seat to securely stow your helmet on arrival, relieving riders of the hassle of carrying their helmet with them or worrying it will get stolen while away from the bike.

For urban riders who are the CE 04’s target market, this setup seems ideal. They probably won’t even consider whether the CE 04 is technically a scooter or a motorcycle as long as it provides another piece to their urban mobility puzzle—along with ride-hailing services, taxis, and mass transit that all allow them to eschew car ownership.

Sweden is testing a semi-truck trailer covered in 100 square meters of solar panels https://www.popsci.com/technology/scania-solar-truck/ Fri, 01 Sep 2023 19:00:00 +0000 https://www.popsci.com/?p=567581

Europe’s seven largest commercial truck manufacturers agreed in 2020 to cease producing diesel vehicles within two decades’ time, and have been aggressively working towards meeting that goal ever since. On August 31, one of those companies announced its latest potential tool in the emissions-heavy industry’s transition towards a more sustainable future. Instead of revolutionizing what’s underneath a semi-truck’s hood, however, Sweden’s Scania aims to take advantage of all the free real estate surrounding the tons of cargo in transit on roadways.

Per a release from Scania, the company recently partnered with Uppsala University and the energy company Midsummer to develop a 560-horsepower plug-in hybrid semi-truck prototype whose 60-foot-long trailer is wrapped in 100 square meters of solar panels. According to CleanTechnica, the additional solar powered boost could supply the truck with an additional annual driving range of up to 5,000 kilometers in Sweden—a promising figure, given the prototype’s location.

The Scandinavian nation isn’t exactly known for its endless days of sunshine. July in Stockholm, for example, only experiences clear skies a little over half the month on average—and that’s the highest rate for the entire year. November, by contrast, is cloudy nearly 75 percent of the month. But in this case, the overcast skies’ regularity works to the project’s advantage.

[Related: Does Hyundai’s rooftop solar panel change the fuel-economy equation?]

“We specifically wanted to see if it made sense in Sweden, because if you go to places such as Southern Europe, Australia or North Africa, there’s obviously a lot more sunshine,” explained Eric Falkgrim, a Technology Leader at Scania’s Research and Innovation department and the solar-powered truck’s project manager, in the August 31 announcement. “If it can work here in the less sunny and somewhat darker conditions then that would confirm the widespread validity of the project.”

Falkgrim noted that although the concept of slapping solar panels atop a semi-truck trailer may initially seem relatively simple, the logistics were anything but easy. “It’s a little bit of a wild and crazy idea because it comes with a lot of new hardware and software systemization and development, to make it safe to handle the transfer of power, and to handle [design] faults,” he continued.

Generally speaking, solar panels aren’t optimized for near-constant traveling. As such, it’s “fairly involved from a technical point of view,” said Falkgrim. Despite only recently starting prototype testing on Sweden’s public roads, he explained the project is “about seeing if the solution makes sense, and so far we believe it does.” Although such a design isn’t expected to become widespread on roadways for a few years, Scania’s initial testing shows the tech is not only feasible, but promising.

What’s the most sustainable way to mine the largest known lithium deposit in the world? https://www.popsci.com/environment/lithium-mining-mcdermitt-caldera/ Wed, 30 Aug 2023 20:30:00 +0000 https://www.popsci.com/?p=567117

The McDermitt Caldera in Nevada and Oregon could hold up to 100 megatons of lithium. Now companies are proposing a new method for mining it.

At first glance, the McDermitt Caldera might feel like the edge of the Earth. This oblong maze of rocky vales straddles the arid Nevada-Oregon borderlands, in one of the least densely populated parts of North America. 

But the future of the modern world depends on the future of places like the McDermitt Caldera, which has the potential to be the largest known source of lithium on the planet. Where today’s world runs on hydrocarbons, tomorrow’s may very well rely on the element for an expanding offering of lithium-ion batteries. The flaky silver metal is a necessity for these batteries that we already use, and which we’ll likely use in far greater numbers to support mobile phones, electric cars, and large electric grids.

Which is why it matters a ton where we get our lithium from. A new study, published in the journal Science Advances today, suggests that McDermitt Caldera contains even more lithium than previously thought and outlines how the yet-to-be-discovered stores could be extracted. But these results are unlikely to ease the criticisms about the environmental costs of mining the substance.

[Related: Why solid state batteries are the next frontier for EV makers]

By 2030, the world may require more than a megaton of lithium every year. If previous geological surveys are correct, then the McDermitt Caldera—the remnants of a 16-million-old volcanic supereruption—could contain as many as 100 megatons of the metal

“It’s a huge, massive feature that has a lot of lithium in it,” Tom Benson, one of the authors of the new paper and a volcanologist at Columbia University and the Lithium Americas Corporation.

One high-profile project, partly run by Lithium Americas Corporation, proposes a 17,933-acre mine in the Thacker Pass, on the Nevada side of the border at the caldera’s southern edge. The project is contentious: Thacker Pass (or Peehee Mu’huh in Northern Paiute) sits on land that many local Indigenous groups consider sacred. Native American activists are continuing to fight a plan to expand the mine-exploration area in court. 

But not all of the lithium under McDermitt’s rocky sands ranks the same. Most of the desired metal there comes in the form of a mineral called smectite; under certain conditions, smectite can transform into a different mineral called illite that can sometimes also be processed for lithium. Benson and his colleagues studied samples of both smectite and illite drilled from the ground throughout the caldera. “There’s lithium everywhere you drill,” he says. 

Previously, geologists assumed that you could find both smectite and illite in a wide distribution across the caldera, but the authors only found the latter in high concentrations in the caldera’s south, around Thacker Pass. “It’s constrained to this area,” explains Benson.

Benson et al. (2023)

That’s important. Benson and colleagues think that the caldera’s illite formed when lithium-rich fluid, heated by the underlying volcano, washed over smectite. In the process, the mineral absorbed much of the lithium. Consequently, they project the illite in Thacker Pass holds more than twice as much lithium than the neighboring smectite.

“That’s really helpful to change exploration strategy,” Benson says. “Now we know we have to stick in the Thacker Pass area if we want to find and mine that illite.”

Some of Thacker Pass’s proponents believe that would result in fewer costs and less damage from mining. Anyone who deals with lithium is, on some level, aware of the environmental costs. The recovery process produces pollutants like heavy metals, sucks up water, and emits tons of greenhouse gases. By one estimate, fitting a new electric vehicle with its lithium battery can result in upwards of 70 percent more carbon emissions than building an equivalent petrol-powered car (although the average electric car will more than make up the difference with day-to-day use).

That said, not all extraction is the same. There are two main types of lithium sources: brine recovery and hard-rock mining. Some of the lithium we use comes from super salty pools. Over millions of years, rainwater percolates through lithium-containing rocks, dissolves the metal, and carries it to underground aquifers. Today, humans pump brine to the surface, evaporate the water, add a slurry of hydrated lime to keep out unwanted metals, and extract the lithium that’s left behind. Much of the world’s brine lithium today comes from the “lithium triangle” of Argentina, Bolivia, and Chile—one of the world’s driest regions.

Alternatively, we can directly mine lithium ores from the earth and process them as we would with most other metals. Separating lithium from ore typically involves crushing the rock and heating it up to temperatures of more than 1,000 degrees Fahrenheit. Getting to those high temperatures often requires fossil fuels in the first place. This method is less laborious and costly than brine extraction, but also far more carbon-intensive.

[Related: Inside the high-powered process that could recycle rare earth metals]

McDermitt Caldera’s smectite and illite belong to what some lithium watchers see as a new third category of extraction: volcanic sedimentary lithium. When volcanic minerals containing lithium flow into nearby valleys  and react with the loose dirt, they leave behind lithium-rich sediments that require little energy and processing to separate.

With the new alternative, mining proponents claim they can drastically reduce the environmental impact of their current and future activities at Thacker Pass. And the research by Benson’s team seems to suggest that, if lithium companies probe in the right places, they might get rewarded more for their efforts.

But this is likely little comfort to lithium-mining opponents in Oregon and Nevada, whose criticisms will be considered as the Bureau of Land Management maps out drilling in the deposit. Their case parallels those of Indigenous Chileans who oppose lithium extraction near their homes in the Atacama and locals fighting a lithium mining project near Portugal’s northern border. Together, they’re fighting a world that’s growing hungrier for lithium, along with new ways and places to exploit it.

Piloting a new Bugatti Chiron Super Sport down the Pacific Coast Highway on a random Saturday afternoon is a bucket-list item for anyone who loves cars as much as I do. Bystanders crane their necks as the Bugatti roars by; it’s not often these beasts are seen in the wild. 

This French-made Bugatti is very, very expensive and very, very powerful. These $4 million(ish) cars can accelerate from zero to 62 miles per hour in 2.4 seconds, and the top speed for the Chiron Super Sport is 273 miles per hour. That’s speedier than Japan’s Shinkansen bullet train, by the way. 

However, what makes this machine interesting is not just its beating heart, which is the car’s 1,600-horsepower engine. The car sports a sleek, prowling silhouette with wide aerodynamic scoops carved from the flanks, and cathedral-like buttresses anchoring the rear. It’s also unique in its engineering; built on a hand-constructed carbon fiber monocoque (the car’s structural frame), the Chiron Super Sport is powered by 16 cylinders and four turbos, which breathe more air into the combustion chamber to fan the flames. 

This vehicle, even at its base configuration, sets itself apart with features like diamond membranes in the Accuton audio system and titanium in the exhaust system. 

Let’s take a closer look at the unique touches that will take your breath away, even when the Chiron Super Sport is sitting perfectly still.

A car celebrating a ‘Golden Era’

Bugatti customers can request a customized vehicle through the brand’s Sur Mesure program (“custom made” in French). Anything goes in the design studio, and one customer chose a Chiron Super Sport to be the canvas for a celebratory mural honoring the company’s history. Bugatti designer Jascha Straub rose to the challenge and led a team that invested 400 painstaking hours drawing 45 sketches by hand on the sides of the car. 

For this specific vehicle (dubbed “Golden Era”), Straub tells PopSci that it was important to the design team to use pencil sketches directly on the car. The pencils they chose incorporate a bit of wax, giving the drawings an oil pastel effect. “There are easier ways to do it, like using a pen or marker, but a pen drawing doesn’t look like a pencil sketch,” he says. “We wanted to keep the grain and shading and highlights intact, which was why it was clear we had to use pencil.” 

During the first set of tests, the designers used body prototype panels and sketched directly on the paint, then covered it with a transparent protective layer called clear coat. The problem, they discovered, was that the clear coat cracked atop the pencil markings. As a result, the designers defined a process to achieve the desired effect: First, a light layer of clear coat was laid on top of the gold paint, and then the images were sketched on top with professional-quality Prismacolor and Polychromos pencils. Then they added another thin layer of clear coat, and the artists sketched right on top of that. Every image was drawn at least three to four times, Straub says. 

And there’s more: just above the gear shifter, the dashboard on all of these vehicles is fitted with embedded tweeters each using a one-karat diamond membrane for extremely low-distortion, high-quality sound. The membrane looks like a contact lens, but made from the hardest naturally-occurring substance on Earth. Because diamonds are so strong, the sound waves pass through them quickly and without warping. Paired with titanium parts, the Accuton audio system is about as good as it gets.

So what’s a W16 engine?

The Chiron Super Sport’s W16 engine—which is currently the only 16-cylinder powertrain in a car—does the work of moving this automotive cathedral on wheels from place to place. First seen in the brand’s 2005 Veyron, the W16 is made up of 3,500 individual parts, each piece assembled by hand. 

Some quick engine background: A V8 engine has the “V” in it because of its shape; two banks of four cylinders each are arranged in a V configuration. In this case, the W16 has the “W” in the name because the cylinders are arranged in a ‘W’ configuration for efficiency of space. Essentially, the engineers at Bugatti created a 16-cylinder engine that is the size of a 12-cylinder engine. 

But this W16 is more than just the sum total of two V8s. Bugatti’s W16 is enhanced by four turbos (two on each cylinder bank). Typically, turbos are added to boost power to a smaller engine, but that’s not the case here, clearly: The engine is massive and the turbos are the icing on top. An intricate water-cooling setup keeps it running smoothly without overheating. For that matter, the brand turned to titanium for the exhaust system, as the W16 kicks off a lot of heat. This iconic engine setup is as distinctive for its artistry as its sheer power.

What comes next for Bugatti?

Right now, the French company’s future is uncertain. 

A century after he founded the company, Ettore Bugatti himself might be surprised to see his company still building cars in his name. (Bugatti died in 1947.) Even more so, he might be shocked to learn that Croatian EV-maker Rimac owns a majority stake in Bugatti, with plans to electrify the brand. He’d surely find kinship with Rimac’s founder and CEO, the young Mate Rimac himself, who kick-started his career converting the powertrain of his 1984 BMW 3 Series from internal combustion to electricity.

While former Bugatti CEO Stephan Winkelmann has already said that the W16 engine is “the last of its kind,” that doesn’t necessarily mean the supercar builder is finished with massive powertrains. If the automaker takes a tip from Lamborghini, it may opt for a high-powered hybrid going forward. The partnership with Rimac is surely going to charge things up.

This article was originally featured on Hakai Magazine, an online publication about science and society in coastal ecosystems. Read more stories like this at hakaimagazine.com.

Satyam Tripathi, a 27-year-old seafarer from Uttar Pradesh, India, leans against the railing of the MT Pablo, the oil tanker that has been his home for the past several months. Though the days at sea often blur together, today stands out as vividly as the South China Sea below. Today is his birthday.

Moments later, his mother calls on WhatsApp. How are you? she asks, forgetting her birthday wishes for her usual motherly enquires: are you as happy at sea as I know you to be on land? Tripathi had acclimatized quickly to life in the merchant navy. The oil tanker is a surprisingly social place, and his head is filled with romantic ideas of a life on the ocean. He reassures her: yes, mother, I’m still happy.

That afternoon, on May 1, 2023, the Pablo exploded off the Malaysian coast.

The crew were thrown by the blast. Adrift in the ocean, clinging to charred metal, most of the ship’s 28 crew waited anxiously for nearby ships to scramble to their rescue.

Twenty-five seafarers were saved in the immediate aftermath of the explosion. The Malaysian Maritime Enforcement Agency spent days searching for the rest. But three remain unaccounted for, Tripathi among them.

Footage of the incident spread quickly across the messaging service Telegram, where fellow seafarers prayed for the missing crew. But within hours, rumors began to swirl of what kind of ship the Pablo really was.

As staff at the ship-tracking service Tanker Trackers noted, the Pablo had spent years smuggling Iranian oil. The vessel also featured on a list of ships under investigation for sanctions-busting by the organization United Against Nuclear Iran. It quickly became clear that for as long as Tripathi had been working on the ship, the vessel he’d called home had been smuggling oil for the Iranian regime.

The ship was a member of the so-called shadow fleet, which emerged in 2018 shortly after the United States reimposed a flood of sanctions against Iran. The sanctions had been waived in 2015 as part of an international effort to end Iran’s nuclear program. But in May 2018, then-president Donald Trump reversed course. In response, Iran enlisted a fleet of vintage tankers to secretly transport its oil without US oversight.

These ships are in poor shape. Many, says Samir Madani, cofounder of Tanker Trackers, were on their way to the scrapyard. “But buyers would show up with a slightly better offer, and then keep them operating for a few more years,” he says.

So, too, with the Pablo. Before it was rechristened, the vessel was variously known as the Olympic Spirit II, the Mockingbird, the Helios, the Adisa, and a handful of other names. Already past its prime, the ship was sold to an undisclosed buyer for demolition. But a few days later, the deal quietly fell through, and the vessel began operating in the shadows.

Tripathi’s family only learned he was missing a few days after the explosion. By then, the search for survivors had been called off.

Shubham Tripathi, one of Satyam’s two brothers, received a single phone call from Satyam’s employer: “We were told there had been a disaster, that he was missing, but that no one was looking for him.”

Desperate, Shubham took to Google. “That is when I saw everyone talking about the smuggling.” It was his first time hearing about the shadow fleet, and he was shocked by what he read. But of one thing he was certain: “Satyam did not know.”

His assumption is not simply brotherly protectiveness. Michelle Bockmann, a senior analyst at Lloyd’s List Intelligence, a shipping industry intelligence and analytics firm, says that “to suggest that any of the crew on board a ship like Pablo are somehow aware of the smuggling is a really unfair assumption to make.”

As far as Satyam was aware, he was undertaking a nine-month contract as a deck fitter on board a legal vessel. He’d found the job through SeaSpeed Marine, a certified crew management agency in Mumbai, India. It appeared to be an entirely legitimate and respectable job, and he was praised by his friends back home.

Yet the same clandestine operations that keep the illegal oil flowing also make it all but impossible for the Tripathi family to find closure. The ship’s registered owner, Pablo Union Shipping, is a shell company that cannot be traced. The vessel’s insurance is listed as “withdrawn” on most shipping websites. “We have complained, but what else can we do?” Shubham says. “They do not care for us.”

With no one to claim responsibility for the wreckage, the Pablo now sits abandoned—a hazard to ships off the Malaysian coast.


Working on a decrepit ship is dangerous. But those who did know the Pablo’s true purpose routinely put the crew’s lives in jeopardy.

Before the explosion, Satyam’s Facebook activity showed multiple check-ins in Malaysia, where the shadow fleet conducts risky ship-to-ship transfer operations—passing oil from one tanker to another to disguise its origin. These outlaw tankers conduct their transfers far out at sea, often with their mandatory automatic identification system location trackers disabled. They also overlook standard safety procedures. “These operations happen without tugboats and a boom line to assist,” says Madani.

Against that backdrop, the Pablo’s fate is likely a preview of what’s to come says Sam Chambers, a shipping expert and editor at Splash, a shipping industry trade magazine.

In late 2022, in response to Russia’s invasion of Ukraine, the European Union and G7 countries slapped sanctions on seaborne Russian oil. Like Iran, Russia is turning to the shadow fleet, often recruiting the very same tankers—staffed with crews sourced through the same crew management companies—that have experience smuggling Iranian oil.

Chambers says that with Russia joining Iran in seeking out the shadow fleet, there is a growing risk of substandard vessels running into trouble.

Right now, many more people like Satyam are unknowingly engaging in oil smuggling, having their lives put at risk to circumvent international sanctions. It’s likely that many more will suffer for it.

The electric version of Ford’s F-150 pickup, the Lightning, came out in 2022. Now, the automaker is revealing a limited-edition matte-black version of the electric truck. Cloaked in as much black as possible, it’s gorgeous. 

To get the vehicle to be this matte black color, Ford has had it outfitted in a 3M vinyl wrap. Parts of the truck, like the side-view mirrors or details on the charge-port door, retain a normal glossy black paint color, which Ford calls “agate” black. 

Ford has continued the black theme with other parts of the truck. For example, the 22-inch wheel rims are black, and the lugnuts are—you guessed it—black. The Ford logo in the front, a famously blue oval, is now black. You may also be able to imagine what’s going on in the interior—black leather seats and a black center console.

The vehicle has a Platinum-level trim, the fanciest Lightning version available. The matte-black edition will cost buyers $97,995, and Ford will only make 2,000 of them when it starts delivering them next year. A regular Platinum-level Lightning costs $91,495.

Black is a hot color choice

The arrival of such a chic vehicle certainly makes a bold appearance, but it also can invite a conversation around how a design like this would fare in our increasingly warm summers. After sitting in the sun, an all-black car will probably get toastier than a light-colored car.

In fact, a study published in 2011 in the journal Applied Energy studied just this topic, focusing on a black Honda Civic and a silver Honda Civic parked in the sun on a day in July 2010, in Sacramento, California. The cars soaked in the sun for about an hour, and then had their air conditioning run for about half an hour, and they went through that cycle five times. 

The researchers measured the temperature of different parts of the cars as time went on. The roof of the black car reached temperatures of around 176 degrees Fahrenheit or more. The roof of the silver car stayed relatively cooler, never getting hotter than 140 degrees. As for the back seat, it hit over 165 F in the black car and around 156 F in the silver car. The cabin air temp reached higher maximum temps in the black car than the silver car, as did ceiling temperatures. In other words, parts of the black car got hotter than the same parts of the silver car. (The difference between the windshield and dashboard temperatures of each vehicle wasn’t too dramatic, though.) 

Ronnen Levinson, the first author on the study and as a staff scientist at the Lawrence Berkeley National Laboratory in California, explains that there are several reasons that cars get hot when they’re in the sun. The first is actually the windows. “If you’re trying to manage the temperature inside the car, the most important thing to do is worry about the glass,” he says. “During the day, you have a lot of sunlight coming in through those windows, and that, more than anything else, is going to heat the car cabin.” This same phenomenon is why homes and buildings sometimes make use of solar-control windows, to keep a house cooler. 

The next factor to think about is the obvious one: the paint color. A black car will get hotter than a white or silver one. “When the painted metal is in the sun, if it is an ordinary black, it is going to get much hotter than an ordinary white,” he says. That’s because white can reflect more light than black. 

The third variable is the cabin interior: he says that ideally the seats as well as parts like the inside of the doors should be lighter in color, too. The way the interior comes into play is that it can keep radiating heat after the air conditioner has been cranked up. “It actually takes quite a while to lower the cabin temperature,” he says. “And the reason is that all of the solid objects in the cabin, they’ve been cooking in the sun—they keep releasing heat.” 

Bottom line: A car with a white or silver paint job and a light-colored cabin is going to stay cooler in the sun than a very dark car, and don’t forget that the windows are actually a big culprit in terms of the vehicle getting toasty, regardless of its color. To deal with the dashboard temperature issue, consider a sunshade for the windshield.

Preconditioning

But don’t let this factor deter you from pursuing the Darth Vader look for your pickup, as there are steps to make the issue better. To mitigate the heat, Vince Mahe, the Lightning’s chief engineer, advises opening the windows and making use of the seat-cooling function, which he says draws less energy than the air conditioner. In an electric car, running air conditioning or heating (as well as other factors) can influence its range. Mahe says that the heater “hurts the range most.” 

There’s a step that customers can take at home before they unplug their EV, too, whether they want it to be cooled down in the summer or warmed up in the winter before they depart. “We tell customers in wintertime to do pre-conditioning, so that they can get the battery warmed up, to run at optimal temperature,” he says. That involves having the truck warm up while it’s still plugged into its charger. Here’s more from Ford on preconditioning a Lightning.

Acura's first EV is the ZDX. It comes out next year with a starting price of $60,000. Kristin Shaw

Acura’s first EV, the ZDX, debuted as a concept car almost exactly a year ago. As of last week, the ZDX is a reality, with deliveries expected for early next year. Acura plans to boost adoption as quickly as possible to support the ZDX and the rest of its EV dreams, and it has some ambitious plans to make it happen, with billions of dollars invested in the future. 

Starting at $60,000, the 2024 Acura ZDX includes an estimated 325 miles of range for the single-motor rear-wheel-drive version. ZDXs with all-wheel drive are expected to have a range of 315 miles, and the Type S should have 288 miles of all-electric range and 500 horsepower to boot. Acura says the new SUV can tow up to 3,500 pounds with rear-wheel or all-wheel drive. 

As Honda’s luxury arm, Acura will likely produce a vehicle with high-quality materials and an elegant layout inside the cabin, including a space below the console for storage since the ZDX doesn’t require a transmission tunnel. Beyond just the ZDX, take a look at the automaker’s multi-faceted plan for the battery development, charging infrastructure, and more. 

Betting on batteries—and more

Acura’s new ZDX is built on GM’s Ultium battery platform, a flexible and modular system used for GMC’s Hummer EV and Cadillac Lyriq SUV (in fact, the exterior dimensions of the ZDX mirror the Lyriq’s). As such, Acura’s near future is tied closely to GM’s for charging protocols. 

When GM switches to Tesla’s North American Charging Standard (NACS), the ZDX will as well, between 2025 and 2026, executive vice president of Honda Motor Company Shinji Aoyama said during an interview along with Jay Joseph, American Honda’s vice president of sustainability and business development, and American Honda Motor Company president and CEO, Noriya Kaihara.

Honda is investing heavily in battery infrastructure, development, and manufacturing with its new EV battery facility, a joint venture with LG Energy Solutions. This $3.5 million collaboration in Jeffersonville, Ohio is expected to be completed by the end of 2025.

In the meantime, Aoyama says Acura will start a pilot production of solid-state batteries. Touted as safer, denser, and less susceptible to temperature changes, these types of batteries can pack more power into a smaller footprint. In turn, that will affect the size and shape of future vehicles as well as overall range. However, battery size alone doesn’t help the overall adoption rate, Joseph asserted during the sit-down with PopSci.

“The antidote to range anxiety isn’t bigger batteries. It’s improving the charging infrastructure,” Joseph says.

Acura recognizes that the typically-heavy nature of EVs is a crucial area to research. Currently, EVs weigh a minimum of 4,000 pounds, Aoyama says, but he sees change going forward. That could be addressed through the use of different materials, disparate structures, denser batteries, or all of the above. 

Improving the charging infrastructure

In July, Acura announced it would join Honda, BMW Group, General Motors, Hyundai, Kia, Mercedes-Benz, and Stellantis (the automaker behind Dodge, Ram, Alfa Romeo, Jeep, and others) to create a new charging network joint venture. Together, the consortium plans to build 30,000 EV fast-charging stations across the United States and Canada, using both Tesla’s North American Charging Standard (NACS) and Combined Charging System (CCS).

“A whole bunch of [battery-electric vehicles] have come to the market in a very short time,” says Joseph. “The trend is quite clear: people are moving to BEVs in the same way that people have moved to SUVs over passenger cars.”

This is on the heels of Ford’s surprise proclamation in May that it had entered an agreement with Tesla to allow current Ford EV owners to use Tesla Superchargers across the US and Canada starting in 2024. Also, Ford CEO Jim Farley promised the automaker’s next generation of EVs will include Tesla’s charging plug. GM, Rivian, and Volvo quickly followed suit.

Acura says it’s going much further. It’s not enough to just build charging stations; they must be the high-speed type to allay range anxiety, brand representatives say. Plus, EV drivers need to know that if their map (or app) points them toward a charge point, it will be secure, reliable, and accessible. One of the current challenges for EV drivers is that CCS charging stations are often located behind buildings in poorly-lit areas, and broken chargers stay down for extended periods of time. As a result, drivers don’t feel comfortable, which contributes to poor adoption rates. Joseph says he recognizes that Tesla does a good job monitoring its equipment and the company fixes issues fast. It makes a big difference. 

The US needs to have about 200,000 DC fast charging charge points to meet EV customer demands, and Acura plans to be part of the solution to pain points in today’s market.

“We think we can make an impact,” Joseph says. “If you drive around Europe, charging is ample. Certain corridors are very well supported; it’s effortless. People need for charging to be easy, and that paves the path to adoption.”

No more hybrids

Meanwhile, Acura is finished with hybrids. The NSX, the last of Acura’s hybrid supercars, rolled off the line in November. Acura’s NSX is equipped with a potent combination of three electric motors with a 3.5-liter V6 engine, good for 600 horsepower and 492 pound-feet of torque. It’s an absolute thrill ride.

For all the Acura NSX fans lamenting the end of this vehicle, there’s hope on the horizon. The brand offered a surprise sneak peek of what it’s calling the Performance Electric Vision Design Study last week at Monterey Car Week, and the sketches point to the emergence of a new supercar. You could bet good money there’s an all-electric version of the NSX just around the corner.

Hydrogen

If hybrids are out of the equation, hydrogen isn’t. There’s a delicate balance between supply and demand, and right now affordability of hydrogen is a challenge, Aoyama says. 

“Retail [hydrogen] in California costs $30 per kilogram, and it needs to be about half that,” he says. 

Overall, Acura recognizes much room for innovation, and Joseph sees this as a “once-in-100-years” transformation.

“We are so used to putting liquid molecules [in our cars] and electrons work totally differently,” he says. “The nature of our relationship with energy is changing. There is an adoption curve, but [driving EVs] is truly better and easier over time.”
