Mazda celebrates 35 years of the MX-5 with anniversary model

Cars, Mazda MX-5 / DJ Henderson / January 27, 2025

The 35th Anniversary Edition is the latest in a long line of special edition Miatas, including anniversary cars for the 10th, 20th, 25th, and 30th editions. The focus here was on “classic elegance,” with Artisan Red paint that’s almost burgundy, plus a tan Nappa leather interior that will remind some of the tan leather interiors that Mazda used on some NAs.

The 35th Anniversary Edition is similar to the Grand Touring trim, which means features like heated seats, and Mazda says it has added a limited-slip differential, additional bracing, and some newly tuned Bilstein dampers. There’s also a beige convertible roof and some shiny 17-inch alloy wheels.

It’s also a bit more expensive than other Miatas, with an MSRP of $36,250. That’s $1,620 more expensive than the next-most-expensive six-speed Miata (the Grand Touring), but it does come with the aforementioned extra equipment. Getting a hold of one might be a bit tricky, though—Mazda will only import 300 into the US.

Jeep’s first battery EV is not what we expected: the 2024 Wagoneer S

car review, Cars, First drive, Jeep Wagoneer S / Mike M. / January 26, 2025

This year marks the return of the Jeep Wagoneer, which formerly served as a more luxurious version of the Cherokee, but now hits the market as Jeep’s first full EV. The challenge? How to merge the modern electric lifestyle with the outdoorsy, rugged ethos that defines Jeep as a brand, alongside the more recent addition of the internal-combustion Grand Wagoneer SUV’s enormous luxury.

First of all, the new Wagoneer S wound up much smaller in person than I expected. The overall profile falls more in line with the shape of mid-size electric crossovers including the Kia EV6, Hyundai Ioniq 5, Chevrolet Equinox, and of course, Tesla’s Model Y. But the interior volume belies that relatively compact exterior, with plenty of space for me at 6’1″ (185 cm) to sit comfortably in both the front and rear seats. Total cargo volumes of 30.6 cubic feet (866 L) with the second row up and 61 cubic feet (1,727 L) with the second row folded flat end up mattering less than the large floor footprint, because the height used to calculate those measurements drops with the low sloping roofline and rear window.

Much of the interior space can be attributed to packaging of the Wagoneer EV’s battery. Rather than going for all-out kilowatt-hours in a dedicated skateboard layout, Jeep instead used the Stellantis group’s STLA Large platform, in this case stuffed with a 100.5-kWh lithium ion pack built on 400 V architecture. That’s enough for an EPA-estimated 303 miles of range (487 km), a solid figure but not a seriously impressive efficiency stat. In comparison, the world-beating Lucid Air Pure RWD manages about 40 percent more range per kilowatt-hour and a Polestar 3 AWD does about 18 percent worse. Claimed DC fast charge times of 23 minutes for a 20-80 percent top up, or 100 miles (160 km) in 10 minutes similarly get the job done without standing out from the pack.

That modular STLA Large chassis can house either a full internal-combustion engine, a hybrid powertrain, or fully electric components. The Wagoneer S uses two matching 335 hp (250 kW) motors, front and rear, for a combined 600 hp (447 kW) and 618 lb-ft of torque (838 Nm). In typical EV fashion, the latter comes on quick and makes this undoubtedly the fastest accelerating Jeep ever, as I learned while battling horrendous headwinds in fire-ravaged Southern California (which served as something of a nonstop reminder of the importance of taking baby steps, a la Jeep’s first EV, toward a more sustainable transportation future).

Pushing deep into the “throttle” pedal, the Wagoneer S will happily chirp all four tires in Sport mode. And the jerk thrusting my torso and skull back into the plush seat suggests that Jeep’s claimed 0-60 mph time of 3.4 seconds might just be accurate, potentially thanks to being able to do a true launch by stepping on the brake and gas pedals simultaneously—possible because Jeep chose to retain more standard mechanical brakes rather than a brake-by-wire system as on the EV6/Ioniq siblings and Model Y.

The suspension tuning definitely trends toward the typical tautness of today’s crossover segment, where aspirational sporty dynamics can sometimes create harsh and uncomfortable ride quality. But I still might have ventured to call the Wagoneer S somewhat softer than most of the competition, until the roughest of roads revealed the 5,667 lb (2,570 kg) curb weight. For an EV, that figure falls roughly in the middle of the pack, but this crossover weighs about as much as a full-size internal-combustion three-row SUV.

Still, even at highway speeds (in gale-force winds) or on those roughest of roads, the Wagoneer S remains shockingly quiet. And not just to enhance the experience of the Wagoneer S Launch Edition’s 1,200 W Macintosh sound system. Instead, Jeep exterior designer Vince Galante walked me through the design process, which kicked off with a targeted 0.30 coefficient of drag despite the need to stick with a squared-off, upright SUV posture typical of Jeeps throughout history.

“On the exterior design portion, the aerodynamic drag is our biggest contributor,” Galante told me. “It kind of comes up off the hood, up the A pillar, and tapers down towards the back, and finishes in a square, yet tapered pillar reminiscent of the original Wagoneer. But through the middle of the car, it’s basically ideal for what the wind wants to do.”

From the front or side perspective, this Wagoneer looks almost as boxy as a 1980s Jeep. But a rear viewing angle reveals the massive rear wing creating that illusion, which sits well off the sloping line of the rear roof and glass.

“Anytime we do a floating element, we think ‘Yeah, there’s no way engineering’s gonna let us get away with this,'” Galante laughed. “We work really collaboratively with the engineers, and they were like, ‘Let’s test it. Let’s see what it does.’ And they came back and said, ‘You know, yeah, this has potential. But you guys gotta make it sit off the surface three times more dramatically.'”

Galante estimates the original wing design rose up two inches, while the final production version is more like nine inches off the rear window. He also pointed out a host of other less obvious details, from body panels that step in by fractions of millimeters to differently rounded radii of wheel arch edges, and especially the confluence where the A pillar connects to the body.

“The windshield, the A pillar, the side glass, the mirror, the post that holds the mirror, the fender, everything comes together there,” he said. “I think every vehicle I’ve ever worked on, that was the last thing to finalize in the wind tunnel… I mean, we’re talking tenths of millimeters for some of the iterations that we’re doing in those areas. Especially the front edge of the A pillar, I can recall trying twenty, thirty, forty different radii on there to get that just right.”

All the aero considerations attempt to coax air to stick to surfaces, then break off suddenly and evenly. The rear wing therefore pushes air down toward the rear window, while creating as little turbulence as possible. The final range figure critically—and barely—cracking 300 miles justified so much refinement in Jeep’s new rolling road wind tunnel, thanks to a final Cd of 0.294. Maybe juggling production cost savings of the STLA Large platform dictated such extensive aerodynamic efforts more than a dedicated skateboard battery layout might have, but the resulting quietude that combating those inefficiencies produced does truly border on a luxury experience, even if we’re not quite at Audi (nor Lucid) levels of silence.

On the interior, Jeep also tried to lean into the Wagoneer S’s sustainability, using quality materials with textural designs and as little piano-black plastic as possible. The fabrics, plastics, and aluminum trim come almost entirely from recycled sources—62 percent for suede and 100 percent for fabric and carpeting, in fact—and you’ll see zero chrome anywhere on the car, since chroming is apparently one of the most environmentally deleterious processes in all of automaking.

But the Wagoneer S similarly leans into a tech-heavy user experience, with almost 55 inches of screen visible from the front seats: the gauge cluster, center infotainment, climate controls, passenger dash screen, and digital rearview mirror all contribute to that total. Climate control, especially, seems critical—and an often overlooked element for many EV manufacturers. Rather than a full panoramic glass roof, as on the Lucids and Polestars of the world, this Jeep gets a long sunroof with a retracting insulated cover to keep out heat. The excellent ventilated front and rear seats (and massaging, for the fronts!) also more efficiently cool down passengers.

For my taste, the digitalization of driving went a little too far. I never enjoy a rotating shift knob but this one clicks into gear with a positive heft. I also noticed some pixelation and latency in the gauge cluster’s navigation maps, as if the refresh rate was too slow for the speed I was driving. Not that I started ripping up the road too much in this luxury crossover, or at least, not more often than scientific experimentation demanded (and a similar problem also affected the Dodge Charger EV we drove recently).

Sport mode brought out some of my inner grinning child, but I actually preferred the Wagoneer S in Eco mode. So much power split to the front and rear wheels can create some torque steer, and throttle response that borders on touchy. The electrically assisted steering also prioritizes a heavy on-center zone, then snaps to light inputs with the slightest turn of the wheel, which made holding a steady line slightly distracting.

Instead, Eco dulls down the throttle response and the steering becomes a bit less reactive. The Wagoneer S will then also more regularly disconnect the front wheels for improved efficiency—though at the hubs, rather than the axles, so some reciprocating mass still saps precious electrons.

It would be more efficient to disconnect the rears, but this decision also centers around maintaining some semblance of Jeep-ness. Even if the Wagoneer S aligns most nearly with recent Cherokee and Grand Cherokee models, rather than the off-roady Wrangler and Gladiator or the super-luxe Grand Wagoneer. The forthcoming Trailhawk version promises to double down on the 4×4 capability, with a locking rear differential, better tires, and hopefully better suspension than I experienced on a quick sojourn off the asphalt onto a slightly rutted gravel road east of San Diego.

More importantly, cheaper trims will arrive later in 2025, also, since the Launch Edition’s tall ask of $71,995 almost doubles the starting sticker of a Equinox EV, seriously eclipses either a Model Y, EV6, or Ioniq 5, and also somehow costs more than a Polestar 3 or even a Lucid Air. Jeep so far wants to keep pricing for those lower-spec Wagoneer EVs under wraps, though, even if the heart of the run will undoubtedly help the first electric Jeep more effectively escape from unfortunate comparisons to such stiff competition.

Millions of Subarus could be remotely unlocked, tracked due to security flaws

Cars, privacy, Subaru, syndication / Kelly Newman / January 25, 2025

Flaws also allowed access to one year of location history.

About a year ago, security researcher Sam Curry bought his mother a Subaru, on the condition that, at some point in the near future, she let him hack it.

It took Curry until last November, when he was home for Thanksgiving, to begin examining the 2023 Impreza’s Internet-connected features and start looking for ways to exploit them. Sure enough, he and a researcher working with him online, Shubham Shah, soon discovered vulnerabilities in a Subaru web portal that let them hijack the ability to unlock the car, honk its horn, and start its ignition, reassigning control of those features to any phone or computer they chose.

Most disturbing for Curry, though, was that they found they could also track the Subaru’s location—not merely where it was at the moment but also where it had been for the entire year that his mother had owned it. The map of the car’s whereabouts was so accurate and detailed, Curry says, that he was able to see her doctor visits, the homes of the friends she visited, even which exact parking space his mother parked in every time she went to church.

“You can retrieve at least a year’s worth of location history for the car, where it’s pinged precisely, sometimes multiple times a day,” Curry says. “Whether somebody’s cheating on their wife or getting an abortion or part of some political group, there are a million scenarios where you could weaponize this against someone.”

Curry and Shah today revealed in a blog post their method for hacking and tracking millions of Subarus, which they believe would have allowed hackers to target any of the company’s vehicles equipped with its digital features known as Starlink in the US, Canada, or Japan. Vulnerabilities they found in a Subaru website intended for the company’s staff allowed them to hijack an employee’s account to both reassign control of cars’ Starlink features and also access all the vehicle location data available to employees, including the car’s location every time its engine started, as shown in their video below.

Curry and Shah reported their findings to Subaru in late November, and Subaru quickly patched its Starlink security flaws. But the researchers warn that the Subaru web vulnerabilities are just the latest in a long series of similar web-based flaws they and other security researchers working with them have found that have affected well over a dozen carmakers, including Acura, Genesis, Honda, Hyundai, Infiniti, Kia, Toyota, and many others. There’s little doubt, they say, that similarly serious hackable bugs exist in other auto companies’ web tools that have yet to be discovered.

In Subaru’s case, in particular, they also point out that their discovery hints at how pervasively those with access to Subaru’s portal can track its customers’ movements, a privacy issue that will last far longer than the web vulnerabilities that exposed it. “The thing is, even though this is patched, this functionality is still going to exist for Subaru employees,” Curry says. “It’s just normal functionality that an employee can pull up a year’s worth of your location history.”

When WIRED reached out to Subaru for comment on Curry and Shah’s findings, a spokesperson responded in a statement that “after being notified by independent security researchers, [Subaru] discovered a vulnerability in its Starlink service that could potentially allow a third party to access Starlink accounts. The vulnerability was immediately closed and no customer information was ever accessed without authorization.”

The Subaru spokesperson also confirmed to WIRED that “there are employees at Subaru of America, based on their job relevancy, who can access location data.” The company offered as an example that employees have that access to share a vehicle’s location with first responders in the case when a collision is detected. “All these individuals receive proper training and are required to sign appropriate privacy, security, and NDA agreements as needed,” Subaru’s statement added. “These systems have security monitoring solutions in place which are continually evolving to meet modern cyber threats.”

Responding to Subaru’s example of notifying first responders about a collision, Curry notes that would hardly require a year’s worth of location history. The company didn’t respond to WIRED asking how far back it keeps customers’ location histories and makes them available to employees.

Shah and Curry’s research that led them to the discovery of Subaru’s vulnerabilities began when they found that Curry’s mother’s Starlink app connected to the domain SubaruCS.com, which they realized was an administrative domain for employees. Scouring that site for security flaws, they found that they could reset employees’ passwords simply by guessing their email address, which gave them the ability to take over any employee’s account whose email they could find. The password reset functionality did ask for answers to two security questions, but they found that those answers were checked with code that ran locally in a user’s browser, not on Subaru’s server, allowing the safeguard to be easily bypassed. “There were really multiple systemic failures that led to this,” Shah says.

The two researchers say they found the email address for a Subaru Starlink developer on LinkedIn, took over the employee’s account, and immediately found that they could use that staffer’s access to look up any Subaru owner by last name, zip code, email address, phone number, or license plate to access their Starlink configurations. In seconds, they could then reassign control of the Starlink features of that user’s vehicle, including the ability to remotely unlock the car, honk its horn, start its ignition, or locate it, as shown in the video below.

Those vulnerabilities alone, for drivers, present serious theft and safety risks. Curry and Shah point out that a hacker could have targeted a victim for stalking or theft, looked up someone’s vehicle’s location, then unlocked their car at any time—though a thief would have to somehow also use a separate technique to disable the car’s immobilizer, the component that prevents it from being driven away without a key.

Those car hacking and tracking techniques alone are far from unique. Last summer, Curry and another researcher, Neiko Rivera, demonstrated to WIRED that they could pull off a similar trick with any of millions of vehicles sold by Kia. Over the prior two years, a larger group of researchers, of which Curry and Shah are a part, discovered web-based security vulnerabilities that affected cars sold by Acura, BMW, Ferrari, Genesis, Honda, Hyundai, Infiniti, Mercedes-Benz, Nissan, Rolls Royce, and Toyota.

More unusual in Subaru’s case, Curry and Shah say, is that they were able to access fine-grained, historical location data for Subarus going back at least a year. Subaru may in fact collect multiple years of location data, but Curry and Shah tested their technique only on Curry’s mother, who had owned her Subaru for about a year.

Curry argues that Subaru’s extensive location tracking is a particularly disturbing demonstration of the car industry’s lack of privacy safeguards around its growing collection of personal data on drivers. “It’s kind of bonkers,” he says. “There’s an expectation that a Google employee isn’t going to be able to just go through your emails in Gmail, but there’s literally a button on Subaru’s admin panel that lets an employee view location history.”

The two researchers’ work contributes to a growing sense of concern over the enormous amount of location data that car companies collect. In December, information a whistleblower provided to the German hacker collective the Chaos Computer Computer and Der Spiegel revealed that Cariad, a software company that partners with Volkswagen, had left detailed location data for 800,000 electric vehicles publicly exposed online. Privacy researchers at the Mozilla Foundation in September warned in a report that “modern cars are a privacy nightmare,” noting that 92 percent give car owners little to no control over the data they collect, and 84 percent reserve the right to sell or share your information. (Subaru tells WIRED that it “does not sell location data.”)

“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 report reads.

Curry and Shah’s discovery of Subaru’s security vulnerabilities in its tracking demonstrate a particularly egregious exposure of that data—but also a privacy problem that’s hardly less disturbing now that the vulnerabilities are patched, says Robert Herrell, the executive director of the Consumer Federation of California, which has sought to create legislation for limiting a car’s data tracking.

“It seems like there are a bunch of employees at Subaru that have a scary amount of detailed information,” Herrell says. “People are being tracked in ways that they have no idea are happening.”

California’s air pollution waiver and the “EV mandate” are banned by Trump

Cars, EV adoption / 9u50fv / January 21, 2025

To do this, it eliminates “state emissions waivers that function to limit sales of gasoline-powered automobiles.” That spells bad news for California and the 17 other states that follow the California Air Resources Board’s Zero Emissions Vehicles regulations. California has been granted waivers under the Clean Air Act to set emissions controls within its state borders, but the first Trump administration spent much time and energy battling CARB’s waiver.

The previous moves to block CARB’s waiver were partially successful and only reversed by the US Environmental Protection Agency just over a month ago.

The revised clean vehicle tax credit, which provides up to $7,500 in credit toward the purchase of a new EV, or up to $4,000 for the purchase of a used EV, also looks to be in trouble. The executive order also calls out “unfair subsidies and other ill-conceived government-imposed market distortions that favor EVs over other technologies and effectively mandate their purchase by individuals, private businesses, and government entities alike by rendering other types of vehicles unaffordable.” However, as the clean vehicle tax credit is a part of the tax code, changes to it will require Congress to pass legislation to that effect.

As you might expect, environmental groups are not impressed. “The transition to electric vehicles is opening factories and putting people back to work across the country,” said Katherine García, Sierra Club director of the Clean Transportation for All campaign. “Instead of building upon progress we’ve made, Donald Trump remains intent on fear-mongering around electric vehicles and taking the US back in time while the rest of the world moves forward on auto innovation. Rolling back vehicle emission safeguards harms our health, our wallets, and our climate.”

GM faces ban on selling driver data that can be used to raise insurance rates

Cars, data brokers, General Motors, OnStar, Policy / DJ Henderson / January 17, 2025

The FTC said its complaint alleged that “GM used a misleading enrollment process to get consumers to sign up for its OnStar connected vehicle service and the OnStar Smart Driver feature.” Lina Khan, who is in her final week as FTC chair, said that “GM monitored and sold people’s precise geolocation data and driver behavior information, sometimes as often as every three seconds.”

Settlement not quite finalized

The proposed settlement was approved in a closed meeting by the FTC’s three Democrats, with the two Republicans recorded as absent. The pending agreement will be subject to public comment for 30 days after publication in the Federal Register, and a final FTC decision will be made under the Trump administration.

In addition to location data, the GM/FTC settlement covers “radio listening data regarding specific content, channel, or station; hard braking, hard acceleration, hard cornering, crossing of a designated high-speed threshold, seat belt usage, or late-night driving; and trip time and duration for such events.” GM and OnStar agreed to delete data collected before the settlement and ask third parties to delete data previously shared with them.

GM also “must allow consumers to disable the collection of Location Data from their Vehicles to the extent the Vehicle is equipped with the necessary technology.”

GM issued a press release on the settlement. “Last year, we discontinued Smart Driver across all GM vehicles, unenrolled all customers, and ended our third-party telematics relationships with LexisNexis and Verisk,” GM said. “In September, we consolidated many of our US privacy statements into a single, simpler statement as part of our broader work to keep raising the bar on privacy… As part of the agreement, GM will obtain affirmative customer consent to collect, use, or disclose certain types of connected vehicle data (with exceptions for certain purposes).”

Affirmative consent is not required for purposes such as providing driver data to emergency responders, responding to customer-initiated communications, complying with government requests and legal requirements, and investigating product quality or safety problems. While the ban on sharing driving data lasts only five years, the overall settlement would be in place for 20 years.

Trek FX+ 7S e-bike is a premium city commuter

Cars, Class 3 e-bike, e-bike review, trek / 9u50fv / January 17, 2025

Post-pandemic, my creed became “Bicycles deliver the freedom that auto ads promise.” That belief is why I’ve almost exclusively used a bike to move myself around Portland, Oregon since (yes, I have become a Portlandia stereotype).

However, that lifestyle is a lot more challenging without some pedal assistance. For a few summers, I showed up sweaty to appointments after pedaling on a $200 single-speed. So in 2024, I purchased the FX+ 2, based primarily on my managing editor’s review. It’s since been a workhorse for my daily transportation needs for the past year; I’ve put more than 1,000 miles on it in eight months.

So given my experience with that bike, I was the natural choice to review Trek’s upgraded version, the FX+ 7S.

A premium pedaler

First off, my time with the FX+ 2 has been great—no regrets about that purchase. But my one quibble is with the battery. Due to the frequency and length of my rides, I need to charge the bike more often than not, and I sometimes experience range anxiety riding to the opposite side of town. Even though both e-bikes are considered lightweight at 40 pounds, they’re still not the easiest things to pedal sans assist, and I’m reliant on their built-in lighting systems after dark.

But I didn’t have to worry about my remaining charge with the FX+ 7 and its 360 Wh battery. Its extra capacity gives me much less range anxiety, as I can ride without fear of losing juice on the route home. And the LCD on the frame gives you a clear indicator of how much distance and time you have left in your ride, which is always handy. I would caution, however, about relying too much on your estimated distance remaining.

During a 15-mile, hour-long ride while fluctuating between the first two assist levels I had modified, I drained 61 percent of the battery. While the estimated time remaining on my ride was consistent and accurate, the predicted mileage dropped occasionally, although that’s probably because I was changing the assist level frequently.

GM patents a dual-port charging system for EVs with vehicle-to-load

Cars, EV charging, patent / DJ Henderson / January 16, 2025

The battery system on an electric car can either charge—from regenerative braking or an external power supply—or discharge—powering the EV’s motor(s) or supplying that power via so-called vehicle-to-load. As a rule, it can’t do both at once, but General Motors has some thoughts about that. The patent analysis site CarMoses spotted a recent GM patent application for a system that is capable of charging and discharging simultaneously.

The patent describes a “charging system” with a pair of charging ports. One is for drawing power from an external source, just like every other EV. The second charge port is connected to a bi-directional charger, and the battery management system is able to charge the battery pack from the first port while also supplying power from the second port.

That second port could be used to charge another battery, including the battery of another EV, and the patent includes an illustration of three EVs daisy-chained to each other.

The idea of two charge ports on an EV is not unheard of; Porsche’s Taycan (and the related Audi e-tron GT) have one on each side, and it’s an option on the newer PPE-based EVs from those brands, if I’m not mistaken. I have no idea whether GM’s patent will show up on a production EV—car companies patent many more ideas than they ever get around to building, after all.

And I must admit, I’m not entirely sure what the use case is beyond seeing how long of an EV-centipede you could make by plugging one into another into another, and so on. But I am intrigued.

Tire simulation is so good it’s replacing real-world testing

Cars, goodyear, tire / 9u50fv / January 15, 2025

“If it’s a one-second maneuver, you want it to take one second, right? Those millions of degrees of freedom model do not necessarily execute in real time like that. So there’s a translation that has to happen to be able to drive the simulator,” Rohweder said.

Goodyear now has a pair of dynamic simulator centers, one in Akron, Ohio, which opened in 2021, and a second in Luxembourg, which opened in 2024.

The payoff is that it’s now much faster to iterate during development. “Back in the late ’90s, you could count on a half a dozen—maybe up to 10—physical iterations where you’re actually ordering a mold, making tires, and putting them on test. [If] you didn’t get the result, [you would] work your way back through,” Helsel said.

Over time, simulating the tire’s footprint allowed Goodyear to cut that in half, “and then since we’ve really been pushing this higher fidelity tire modeling and now into the simulator, we’ve cut that in half again,” Helsel said. Now, when working with a car manufacturer on tires for a specific model, “we only need basically a build and test confirmation physical [tire], so [we’re] down to one,” Helsel said.

That’s quite a savings—perhaps as many as 13,000 tires and 60,000 miles of test track driving that would otherwise be needed before everything was signed off.

“We’ve done variation in studies with [tire] sizes when we’re setting targets working with the manufacturer before they start the vehicle development,” said Rohweder. “Tire dimension is easy to adjust. Compound, major design changes—when you have the data and you prepare it, you can go into the simulator environment and quickly move around in the design space to find out what the driver feels is most effective and best for shooting on that target. So that’s why we say that the maturity of that first physical iteration is really the benefit,” Rohweder said.

Ban on Chinese connected-car software is almost ready

Cars, connected cars / Beth Washington / January 14, 2025

However, the ban, as written, is not absolute. Companies can seek authorization to import software or hardware that would otherwise be outlawed, but the request would need to satisfy the US government and possibly be subject to conditions.

There are also exemptions for software for vehicles older than model year 2027 and hardware for vehicles older than model year 2030, including parts imported for warranty or repair work. (The government points out that retroactively applying the new rule would be a little pointless as any harm would already be done by vehicles that had compromised systems that predate it going into effect.)

And the final rule would only apply to light-duty vehicles. Anything with a gross vehicle weight rating of more than 10,000 lbs is exempt but will be dealt with in “a separate regulation tailored to the commercial sector in the coming months.”

Auto industry suppliers probably face the most disruption as a result of the new rule—just the presence of a Chinese-made module in a larger system is enough to trigger the import ban. But there should be little disruption to the US car market, at least for now.

Since the rules only go into effect from model year 2027, the few Chinese-made vehicles on sale in the US—models from Polestar, Volvo, Lincoln, and Buick—may remain on sale. However, Polestar’s Chinese ownership may prove somewhat of a sticking point compared to Ford and GM. Ars notes that lawyers representing Polestar met with the Commerce Department last week—we reached out to the automaker for a comment and will update this piece should we hear back.

How GM’s Super Cruise went from limo driving to lane changes and towing

Cars, Super Cruise / Mike M. / January 13, 2025

The Unified Lateral Controller

The algorithm that handles all of that is called the Unified Lateral Controller. “So it’s a single software stack, but it is also modular to adapt with different vehicle configurations, with different driving scenarios, different maneuvers,” Zarringhalam said.

“Let’s imagine that you’re driving a Super Cruise vehicle, and you indicate to the left, or the system automatically decides to make a lane change to the left, and then, for whatever reason, the driver decides that they want to go back, mid-maneuver; they want to go back to the original lane. So you can just indicate to the opposite side, in this case, the right-hand side. Under the hood, in this scenario, everything is jumping. Our target trajectory is jumping from a left-lane maneuver to a right turn. The turn can be very sharp. There could be other objects that narrow the envelope of operation that you’re allowed to function in,” Zarringhalam said.

Again, that behavior has to be consistent and predictable, whether it’s below freezing or in the middle of a heatwave, and things like tire wear must also be taken into account. Or, say, the presence of a trailer, which could be anything from a bike rack with wheels to a three-axle trailer.

“As soon as we detect that the trailer is attached, we run several real-time algorithms—trailer inertial parameters, trailer math, trailer configuration, even how many axles we have, and the control adapts itself to execute lane turning and keep both the vehicle and the trailer at the center of the road,” Zarringhalam said.

That’s done automatically without the driver having to input the information (obviating the problem of someone entering the wrong details), “and if you change the loading or the trailer configuration, even mid-drive—if you pull over, load more weight and continue driving on the same road with Super Cruise active—these learnings happen in a matter of seconds,” Zarringhalam said.

Tesla’s Model Y crossover finally gets a facelift—just in China for now

Cars, Tesla Model Y / DJ Henderson / January 11, 2025

Yesterday, Tesla revealed a facelift for its bestselling Model Y crossover. Or at least it did if you live in China—customers in the US and Europe will need to continue to wait for the revamped electric vehicle.

Better efficiency was a goal—in the past, Tesla simply ignored complaints over its exaggerated range claims, but now it says the Model Y, codenamed “Juniper,” has updated suspension, wheels, and tires that “make the driving experience smoother and quieter.”

Tesla says that range has increased from 427 miles (688 km) to 446 miles (719 km), albeit under the Chinese efficiency testing regime, which produces very different numbers from the more realistic tests used by the US Environmental Protection Agency.

More obvious are the new treatments for the front and rear, with a full-width daylight running light at the front and a full-width rear light. On the inside, Tesla has added ventilated front seats and an infotainment screen for the rear passengers, and there are now blindspot monitors, all additions that will help Tesla stay close to feature parity with its many rivals in that market.

Chinese customers will be expected to pay a price premium for the facelifted model, however. Tesla has increased the price by more than 5 percent, although at $35,939 (263,500 yuan) before incentives, it remains far cheaper than the $44,990 starting price for the Model Y in the US.

Speaking of the US, consumers here wishing to buy a facelifted Model Y probably have a few more months before that becomes possible. The even more outdated Model 3 received its “Highland” update in China in September 2023, with European sales starting a month later, but in the US, the revamped Model 3 only appeared in early 2024. A similar wait for the “Juniper” Model Y should be expected, as the company will need to refit its Model Y production lines at its factories in Germany, California, and Texas before that can happen.

Only 5 percent of US car buyers want an EV, according to survey

Cars, EV adoption / 9u50fv / January 11, 2025

Only 5 percent of US consumers want their next vehicle to be a battery electric vehicle, according to a new survey by Deloitte. The consulting company gathered data from more than 31,000 people across 30 countries as part of its 2025 Global Automotive Consumer Study, and some of the results are rather interesting, as they pertain to technologies like new powertrains, connectivity, and artificial intelligence.

Among US consumers, internal combustion engines (ICE) remain number one, with 62 percent indicating that their next car will not be electrified. Another 1 in 5 would like a hybrid for their next vehicle, with a further 6 percent desiring a plug-in hybrid. (The remaining survey respondents either did not know or wanted some other powertrain option.)

By contrast, only 38 percent of Chinese consumers want to stick with ICE; meanwhile, 27 percent of them want a BEV next. That’s a far higher percentage than in other large nations—in Germany, only 14 percent want a BEV; in the UK and Canada, only 8 percent are BEV-bound; and in Japan, the number is a mere 3 percent.

Meanwhile, hybrids are far more attractive to consumers in most countries. While only 16 percent of Chinese and 12 percent of German consumers indicated this preference, 23 percent of Canadians, 24 percent of UK consumers, and 35 percent of Japanese consumers replied that they were looking for a hybrid for their next car.

Deloitte suspects that some of this reticence toward BEVs “could be due, in part, to lingering affordability concerns.” The hoped-for parity in the cost of a BEV powertrain and an ICE powertrain has still not arrived, and fully 45 percent of US consumers said they did not want to pay more than $34,999 for their next car (11 percent said less than $15,000, 9 percent said $15,000–$19,999, and the remaining 25 percent said $20,000–$34,999.)

Why the reticence?

Despite popular sentiment, there are actually quite a few electric vehicles available for much less than the average new vehicle price of $47,000. But other than the Nissan Leaf, all of them have prices starting with a “3.” (Meanwhile, 75 percent of car buyers in the US buy used cars, and the transition to electrification will not change that underlying reality.)
