take away the grip to learn about grip — A frozen lake and several Lamborghinis provide lessons on traction control Electronic traction control is more important than ever as electric motors proliferate.

Ars does not accept paid editorial content.

From the passenger seat of my Lamborghini Huracn Sterrato, 24 Hours of Daytona winner Corey Lewis gives me a “slow down” hand gesture, urging me to avoid an Urus high-centered on a snow bank. I resist the childish impulse to blast by at full throttle and spray the recovery crew with a fresh layer of snow because I don’t want to be the next driver to cause a scene. Once we pass the group, I punch it again, countersteering into a wide drift as my studded Blizzak winter tires shred through snow and ice, exhaust wide open and barking at redline, cranking through a series of left-right-left transitions until we come back around to the stuck SUV.

Lewis and I both laugheverybody spins at least once while ice-drifting Lamborghinis on Lake Catchima north of Montreal, which played host in February to North America’s Esperienza Neve winter driving academy. This year, Lamborghini invited customers out to tear up the pristine Canadian winterscape in three Sterratos, four Uruses, and two rear-wheel-drive Huracn Tecnicasall told, about $3 million worth of cars.

Drifting in six-figure Lambos might make anyone a little nervous. In the controlled environment of a 30-inch (762 mm)-thick ice sheet, though, the consequences are minimal (there are bruised egos whenever anybody loses control and needs a tow, of course). So much power on the slip-and-slide immediately exposes driver skillor lack thereofdespite 400 studs per tire on the Huracns and 300 per tire on the Uruses providing grip and confidence. Even for a driver as experienced as Lewis, ice-drifting still has its value. For the mere mortals among us, all the more so.

“In the real world, normally, you don’t have the opportunity to kind of test the limits of what understeer and oversteer actually feel like,” Lewis explained as we took a break on the frozen lake. “It makes you just an all-around more controlled driver on the street, whether it’s mixed conditions, highway driving, backroads, or emergency avoidance. I truly believe that events like these are a huge help for people. Plus, it’s fun, too.” Advertisement

I traveled to Lake Catchima hoping to get in on the fun, but I also hoped to learn more about how modern driver’s aids make the current crop of unbelievably powerful supercars approachable for “average” owners. So, for my first round on a coned-off figure-eight, I fiddled with the various drive modes on an Urus Performante.

With TC and ESC fully activated, the super-SUV happily cruises around at tamer speeds. Start to turn the steering wheel, however, and the nannies rein in power to prevent tire spin and slidessafety first, presumably to help drivers avoid ditches and berms while shuttling the family up to Zermatt or Aspen.

Switching into Rally mode and toggling ESC off entirely allowed me to modulate steering and throttle inputs without the computers stepping in to prevent slides. And the 4,740-lb (2150 kg) SUV performed admirably, hooking up the front tires in opposite lock but also shifting weight around predictably when I lifted off the throttle. The sensations changed up entirely in the Sterrato, thanks to the unique power and balance made possible by the naturally aspirated, mid-mounted V10.

When I switched to a rear-wheel-drive Tecnica, I could only manage a few circles before spinning outthankfully, I never needed help to get back underway. It was another lesson learned, though, about progressive and steady inputs eventually leading to smoother donuts.

The biggest surprise? Even in the disadvantaged Tecnica, driving on snow with TC and ESC turned on remained entirely possible without too much tail-happy squirrelliness. Sure, the tire studs helped, but remember, this is a 640-hp (477 kW) supercar. To learn more about how exactly traction control and electronic stability control allowed the entire supercar industry to turn up the wick without regularly risking lives and limbs, I spoke with Lamborghini CTO Rouven Mohr about the evolution of the very nannies that so many automotive reviews regularly bemoan.

“For our product range, we can for sure say the Urus is the most used of our cars to go on a winter holiday or to go skiing,” Mohr said. “But from the development perspective, every car in our product range is running the full set of winter test sessions. This means at least two winters, so we start one winter with the basic calibration and then we have the confirmation with the second winter.” Page: 1 2 Next → reader comments 0 Advertisement Channel Ars Technica ← Previous story Related Stories Today on Ars

Meta says China retailers are reducing digital ad spend

Chinese online retailers have cut back their spending on Facebook and Instagram ads in reaction to President Donald Trump’s tough trade policy with the country.

Meta’s finance chief Susan Li said Wednesday that “Asia-based e-commerce exporters” have reduced their spending with the social media company. It’s likely those firms did so as they prepare for the de minimis trade loophole ending this Friday, Li said during a first-quarter earnings call.

“A portion of that spend has been redirected to other markets, but overall spend for those advertisers is below the levels prior to April,” Li said.

Trump in early April signed an executive order to end the de minimis trade exemptions for Chinese imports, which benefited online retailers like Temu and Shein. Analysts have said they believe that Temu and Shein make up the bulk of Meta’s 2024 China-related sales of $18.35 billion.

Meta’s advertising sales in the Asia-Pacific region were $8.22 billion for the first quarter, the company said. That was below Wall Street projections of $8.42 billion.

Li said that Meta’s second-quarter revenue would come in the range of $42.5 billion to $45.5 billion, which was in line with analysts expectations of $44.03 billion.

“It’s very early, hard to know how things will play out over the quarter, and certainly, harder to know that for the rest of the year,” Li said.

This echoes what Google said last week during its earnings call, warning that it expects headwinds to its advertising business, particularly from the Asia-Pacific region. Similarly, Snap on Tuesday said it had “experienced headwinds to start the current quarter.”

Trump’s China tariffs of 145% also appear to be impacting Meta’s Reality Labs unit, which creates virtual reality and augmented reality devices.

Reality Labs had an operating loss of $4.2 billion while bringing in $412 million in sales during the first quarter.

Meta said its 2025 capital expenditures will come in the range of $64 billion to $72 billion, which is higher than its prior outlook of $60 billion to $65 billion.

“This updated outlook reflects additional data center investments to support our artificial intelligence efforts as well as an increase in the expected cost of infrastructure hardware,” the company said in the earnings release.

Regarding the higher costs of infrastructure hardware, Li told analysts that it’s the result of “suppliers who source from countries around the world.” The higher cost of infrastructure hardware and “higher expected Reality Labs cost of goods sold” has “partially offset” Meta’s lowered projected range for its 2025 total expense, she said.

“There’s just a lot of uncertainty around this, given the ongoing trade discussions,” said Li, adding that Meta is modifying its supply chain as a result.

Microsoft passes its first test on U.S. tariffs with limited portfolio exposure

Microsoft CEO Satya Nadella speaks during an event commemorating the 50th anniversary of the company at Microsoft headquarters in Redmond, Washington, on April 4, 2025. Microsoft Corp., determined to hold its ground in artificial intelligence, will soon let consumers tailor the Copilot digital assistant to their own needs.

President Trump’s tariffs have dominated global news headlines for weeks. During Microsoft‘s earnings call with investors on Wednesday, though, tariffs came up only once, during prepared remarks.

The reference from Amy Hood, Microsoft’s finance chief, had to do with sales of personal computers and Windows operating system licenses to other PC makers.

“Windows OEM and devices revenue increased 3% year over year, ahead of expectations, as tariff uncertainty through the quarter resulted in inventory levels that remained elevated,” Hood said.

While Microsoft does sell Surface PCs and Xbox video game consoles, impact will likely be less direct than it will be on companies that sell physical products.

Still, Microsoft does stand to see second-order effects, like other software vendors. Its clients might feel the effects of higher prices on goods imported into the U.S. and choose to soften their spending, and Microsoft does purchase equipment from other countries.

The Redmond, Washington-based company is investing heavily to buy and install the necessary Nvidia graphics processing units across the world to power OpenAI’s ChatGPT and other artificial intelligence products.

If anything, software might help companies respond in the event that their costs go up because of tariffs, CEO Satya Nadella said on the conference call

“I think if you sort of buy into the argument that software is the most malleable resource we have to fight any type of inflationary pressure or any type of growth pressure where you need to do more with less, I think we can be super helpful in that,” he said. “And so if anything, we would probably have more of that mindset is, how do we make sure we are helping our customers, and then, of course, we’ll look to
share gains.”

The company sells a slew of AI products, including the GitHub Copilot that spits out source code suggestions for developers and the Microsoft 365 Copilot assistant that answers questions in Excel, Teams and other productivity apps.

Microsoft shares traded up about 8% in extended trading after the call. The company reported higher revenue and earnings than analysts had predicted and issued an upbeat forecast.

Court finds Apple, executive lied under oath in Epic Games trial

Court finds Apple, executive lied under oath in Epic Games trial

Apple willfully violated a 2021 injunction that came out of the Epic Games case, Judge Yvonne Gonzalez Rogers said in a court filing on Wednesday.

She wrote that Apple Vice President of Finance Alex Roman “outright lied” to the court about when Apple had decided to levy a 27% fee on some purchases linked to its App Store.

“Neither Apple, nor its counsel, corrected the, now obvious, lies,” Rogers wrote, saying that she considers Apple to “to have adopted the lies and misrepresentations to this Court.”

Rogers added that she referred the matter to U.S. attorneys to investigate whether to pursue criminal contempt proceedings on both Roman and Apple.

The decision is a striking repudiation of Apple’s conduct in the Epic Games trial, which was decided in 2021 and appealed in 2023.

While Apple won the vast majority of counts in the original trial, Epic Games did win some concessions tucked inside a 180-page order. Rogers originally ordered the company to make changes to its app store, allowing software developers to link to their websites inside of iPhone apps for customers to make purchases outside of Apple’s ecosystem.

On Wednesday, Rogers accused Apple of willfully trying to violate her ruling, and she held the company in contempt.

Rogers wrote that it was expected under her ruling that those kind of off-app purchases would not have an Apple commission. But Apple introduced new policies in 2024 that collected a 27% commission from some of those purchases, only a slight discount from the 30% Apple usually collects from in-app purchases. Rogers said nearly every Apple decision on its app-linking policies was anticompetitive.

Rogers wrote that Apple presented evidence to the court of internal deliberations about its rule that were “tailor-made for litigation,” instead of the company’s actual internal discussions.

“In stark contrast to Apple’s initial in-court testimony, contemporaneous business documents reveal that Apple knew exactly what it was doing and at every turn chose the most anticompetitive option,” Rogers wrote. “To hide the truth, Vice-President of Finance, Alex Roman, outright lied under oath.”

Rogers also accuses Apple of withholding documentation of a June 2023 meeting including CEO Tim Cook about how they would comply with the 2021 court order. Rogers said that Apple hid the existence of the meeting from the court until 2025. She also said that Apple abused privilege in order not to share documents that it was supposed to.

Apple had a “a desire to conceal Apple’s real decision-making process, particularly where those decisions involved senior Apple executives,” Rogers wrote.

Former Apple senior vice president and current fellow Phil Schiller did not want Apple to take a commission on web links, but Cook ignored him, Rogers said.

“Cook chose poorly,” Rogers wrote.

The judge ordered, effective immediately, for Apple to stop imposing its commissions on purchases made for iPhone apps through web links inside an app. She also ordered Apple to pay Epic Games’ attorney fees over this specific issue.

“This is an injunction, not a negotiation. There are no do-overs once a party willfully disregards a court order,” Rogers wrote.

An Apple representative did not respond to a request for comment. Roman didn’t immediately respond to a message.

“It’s a huge victory for developers, and it means all developers can offer their own payment service side-by-side with Apple’s payment service,” said Epic Games CEO Tim Sweeney on a call with reporters on Wednesday. “This forces Apple to compete. This is what we wanted all along.”
