Pirelli’s sensor-embedded Cyber Tire is starting to find a whole new niche helping traffic agencies. When we first learned of the smart tire, it was making its debut fitted to McLaren’s then-new plug-in hybrid supercar. As an alternative to a tire pressure monitoring system fitted to the car’s wheels, the Cyber Tire wirelessly reports its temperature and pressure to its car via Bluetooth Low Energy, along with some specific information about the tire itself.

Since then, Pirelli has continued to develop the technology. When it created Cyber Tires for the Pagani Utopia, it allowed a car to tailor its antilock braking and electronic stability control to the specific rubber fitted to the wheels. Right now, a car’s ABS or ESC will be tuned regardless of the tires it’s fitted to.

But a high-performance summer tire acts quite differently from a winter tire, not just because of the composition of the rubber but also due to the tread pattern, depth, and stiffness, not to mention factors like sidewall stiffness. And the Utopia can take advantage of that fact.

After a weekend off, perhaps spent trick or treating, Formula 1’s drivers, engineers, and mechanics made their yearly trip to the Interlagos track for the Brazilian Grand Prix. More formally called the Autodromo Jose Carlos Pace, it’s definitely one of the more old-school circuits that F1 visits—and invariably one of the more dramatic.

For one thing, it’s anything but billiard-smooth. Better yet, there’s elevation—lots of it—and cambers, too. Unlike most F1 tracks, it runs counterclockwise, and it combines some very fast sections with several rather technical corners that can catch out even the best drivers in the world. Nestled between a couple of lakes in São Paulo, weather is also a regular factor in races here. And indeed, a severe weather warning was issued in the lead-up to this weekend’s race.

This was another sprint weekend, which means that instead of two practice sessions on Friday and another on Saturday morning, the teams get one on Friday, then go into qualifying for the Saturday sprint race. The shortened testing time tends to shake things up a bit, and we definitely saw that this weekend.

When Ford electrified its best-selling pickup truck, it pulled out the stops. The F-150 Lightning may look virtually identical to other versions of the pickup, but it’s smoother, faster, and obviously far, far more efficient than the ones that run on gas, diesel, or hybrid power. But the future of the country’s best-selling electric truck may be in doubt.

That’s according to a report in The Wall Street Journal, which claims that Ford’s management is “in active discussions about scrapping” the Lightning. Production had already been suspended a few weeks ago as a result of an aluminum shortage following a destructive fire at a supplier’s factory in New York, which Ford estimates may result in as much as $2 billion of losses to the company.

While Ford told Ars it doesn’t comment on speculation on its future product plans, the automaker said that “F-150 Lightning is the best-selling electric pickup truck in the US—despite new competition from CyberTruck, Chevy, GMC, Hummer and Rivian—and delivered record sales in Q3.”

Tesla’s shareholders are ready to vote tomorrow on whether to give Elon Musk an even more vast slice of the company in an effort to keep him focused on selling electric vehicles. Currently, the trolling tycoon appears a little obsessed with the UK, a place he appears to conflate with Middle Earth, which investors may or may not take into account when making their decision. What they ought to take into account is how many cars Tesla sold last month.

Although Tesla only publishes quarterly sales figures and does not divide those up by region, slightly more granular data is available from some countries via monthly new car registrations. And the numbers for October, when compared year on year to the same month in 2024, should be alarming.

Sales fell by double-digit margins in Sweden (89 percent), Denmark (86 percent), Belgium (69 percent), Finland (68 percent), Austria (65 percent), Switzerland (60 percent), Portugal (59 percent), Germany (54 percent), Norway (50 percent), the Netherlands (48 percent), the UK (47 percent), Italy (47 percent), and Spain (31 percent).

Formula E officially revealed its next electric racing car today. At first glance, the Gen4 machine looks similar to machinery of seasons past, but looks are deceiving—it’s “so much more menacing,” according to Formula E CEO Jeff Dodds. The new car is not only longer and wider, it’s far more powerful. The wings and bodywork now generate meaningful aerodynamic downforce. There will be a new tire supplier as Bridgestone returns to single-seat racing. The car is even completely recyclable.

I’m not sure that everyone who attended a Formula E race in its first season would have bet on the sport’s continued existence more than a decade down the line. When the cars took their green flag for the first time in Beijing in 2014, as many people derided it for being too slow or for the mid-race car swaps as praised it for trying something new in the world of motorsport.

Despite that, the racing was mostly entertaining, and it got better with the introduction of the Gen2 car, which made car swapping a thing of the past. Gen3 added more power, then temporary all-wheel drive with the advent of the Gen3 Evo days. That car will continue to race in season 12, which kicks off in Brazil on December 6 and ends in mid-August in London. When season 13 picks up in late 2026, we might see a pretty different kind of Formula E racing.

LAS VEGAS—About 100 miles from Las Vegas, at the northern end of the Mojave Desert, you’ll find a pretty large pile of sand. The Dumont Dunes formed thousands of years ago as sand from recently dried-up lakes blew in on the wind through gaps in the mountains. We’re talking real Lawrence of Arabia stuff—some dunes hundreds of feet high, and a large amount of it is run as a recreational area by the Bureau of Land Management for activities that include a bit of off-roading.

Which is why we found a trailer full of Mercedes-Benz engineers and some preproduction prototype electric GLCs at work out there. When we last saw the next GLC, it was earlier this year at a German test track, wearing one of those black-and-white digital camouflage wraps that obscure the finer details of a new design. The automaker is dealing with the finishing touches ahead of the model going into production next year. The hardware is signed off on, but there’s plenty of code to tweak and calibrations to perform, including making sure that even when the terrain gets loose, the handling won’t.

While I’m sure that the vast majority of GLC customers’ experience with rough surfaces won’t extend past the odd, particularly bad pothole, the car is being engineered to cope with much more. When fitted with the optional air suspension, the ground clearance can increase to up to 8.1 inches (206 mm) at low speed and 7.2 inches (183 mm) even up to highway speed, as long as the car is in the more extreme of the two Terrain modes. That allows for approach and departure angles as much as 21.4 degrees (approach) and 22.6 degrees (departure).

2017 feels like another era these days, but if you cast your mind back that far, you might remember Tesla CEO Elon Musk’s vaporware Roadster 2.0. Full of nonsensical-sounding features that impressed people who know a little bit about rockets but nothing about cars, the $200,000 electric car promised to have a suction fan and “cold gas thrusters,” plus 620 miles (1,000 km) of range and a whole load of other stuff that’s never happening.

Plenty of other electric automakers have introduced electric hypercars in the eight years since Musk declared the second Roadster a thing, with no sign of it being any closer to reality, if the latest job postings are accurate. And it seems that over time, a lot of the people who gave the company a hefty deposit—some say interest-free loan—have become tired of waiting and want their money back.

And that’s not quite so easy, it turns out. Musk’s current Silicon Valley rival is the latest to discover this. According to Sam Altman’s social media account, he placed an order for a Roadster on July 11, 2018, with a deposit of $45,000 ($58,206 in today’s money). But after emailing Tesla for a refund, he discovered the email address associated with preorders had been deleted.

When Hyundai’s E-GMP platform for electric vehicles arrived on the market, it cemented the Korean automaker’s place as one of the leaders of its industry. And in the absence of an influx of Chinese EVs, the Ioniq range of cars, crossovers, and SUVs is about as leading-edge as you’ll find in showrooms right now, particularly mainstream brands.

The first of the E-GMP cars was the Ioniq 5, which looks like a 1980’s hatch scaled up to the midsize crossover segment. Now made in the US, it has been a firm hit—and at the beginning of the month just got a hefty price cut, to boot. A midsized sedan followed, but these are a less common sight here given American car-buying tastes. Those tastes shaped the Ioniq 9, though.

The underlying technology might hail from Hyundai’s Namyang R&D center in South Korea, but the Ioniq 9 is the result of that technology expressed through the tastes of suburban America. Not so much the exterior styling, though. The hood is too low, the corners are more rounded, and it’s generally a less-threatening shape than the average domestic three-row SUV.

Just a few weeks ago, automakers were celebrating a healthy third quarter for electric vehicle sales. General Motors was looking particularly flush, with EV sales up 104 percent for the year to date compared to the first nine months of 2024. But the strong EV sales in Q3 were seemingly due to the imminent end of the federal tax credit that expired at the end of September, with many consumers buying a car sooner than planned to take advantage of the $7,500 incentive.

The Trump administration has been altering the regulatory environment in other ways to discourage clean technologies, canceling infrastructure initiatives and turning a blind eye to pollution. On top of that, the impact of the president’s chaotic trade war has driven up prices and is cooling demand. Two weeks ago, GM told investors that things are looking so bad that it will take a $1.6 billion hit to its bank accounts as it realigns manufacturing capacity going forward.

Now we can see some of the impact of that realignment. According to The Detroit News, 1,200 workers are being laid off at GM’s EV-building Hamtramck Assembly Center near Detroit, which will move from two shifts a day to just one in early January.

The Japan Mobility Show kicks off in Tokyo this week, and Mazda is using the occasion to show off a couple of concepts it says embody a theme called “the joy of driving fuels a sustainable tomorrow.” One of these is the Vision X-Coupe, which Mazda says shows off the evolution of its KODO design language—something we first saw at the Tokyo show a decade ago.

You can see a clear visual link between the renderings of the Vision X-Coupe and some of Mazda’s current models like the 3 hatchback or the CX-30 crossover, but translated through the long, low form factor of a four-door coupe. The design language is perhaps less interesting than some of the sustainability ideas that Mazda is exploring here, though.

The powertrain is a 503 hp (375 kW) plug-in hybrid that uses a two-rotor turbocharged rotary engine as the internal combustion part of the equation. Mazda says it should have a total range of 500 miles (800 km), with a range of 100 miles (160 km) on battery power alone.
