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.

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

Donald Trump sending ‘top of the line’ weapons to support NATO in Ukraine war

Donald Trump sending 'top of the line' weapons to support NATO in Ukraine war

Donald Trump has agreed to send “top of the line weapons” to NATO to support Ukraine – and threatened Russia with “severe” tariffs if it doesn’t agree to end the war.

Speaking with NATO secretary-general Mark Rutte during a meeting at the White House, the US president said: “We’ve made a deal today where we are going to be sending them weapons, and they’re going to be paying for them.

“This is billions of dollars worth of military equipment which is going to be purchased from the United States, going to NATO, and that’s going to be quickly distributed to the battlefield.”

It comes as Ukrainian president Volodymyr Zelenskyy said he had a “very good conversation” with Mr Trump late on Monday. He thanked him for the “willingness to support Ukraine and to continue working together to stop the killings”.

Weapons being sent from to Ukraine include surface-to-air Patriot missile systems and batteries, which the country has asked for to defend itself from Russian air strikes.

Mr Trump also said he was “very unhappy” with Russia, and threatened “severe tariffs” of “about 100%” if there isn’t a deal to end the war in Ukraine within 50 days.

The White House added that the US would put “secondary sanctions” on countries that buy oil from Russia if an agreement was not reached.

Analysis: Will Trump’s shift in tone make a difference?

As ever, there is confusion and key questions are left unanswered, but Donald Trump’s announcement on Ukraine and Russia today remains hugely significant.

His shift in tone and policy on Ukraine is stark. And his shift in tone (and perhaps policy) on Russia is huge.

Read Mark’s analysis here.

Mr Zelenskyy previously criticised Vladimir Putin’s “desire to drag [the war] out”, and said Kyiv was “working on major defence agreements with America”.

It comes after weeks of frustration from Mr Trump over Mr Putin’s refusal to agree to an end to the conflict, with the Russian leader telling the US president he would “not back down” from Moscow’s goals in Ukraine at the start of the month.

Trump threatens Russia with ‘severe’ tariffs’

During the briefing on Monday, Mr Trump said he had held calls with Mr Putin where he would think “that was a nice phone call”, but then “missiles are launched into Kyiv or some other city, and that happens three or four times”.

“I don’t want to say he’s an assassin, but he’s a tough guy,” he added.

Earlier this year, Mr Trump told Mr Zelenskyy “you’re gambling with World War Three” in a fiery White House meeting, and suggested Ukraine started the war against Russia as he sought to negotiate an end to the conflict.

After Mr Trump’s briefing, Russian senator Konstantin Kosachev said on Telegram: “If this is all that Trump had in mind to say about Ukraine today, then all the steam has gone out.”

Meanwhile, Mr Zelenskyy met with US special envoy Keith Kellogg in Kyiv, where they “discussed the path to peace” by “strengthening Ukraine’s air defence, joint production, and procurement of defence weapons in collaboration with Europe”.

He thanked both the envoy for the visit and Mr Trump “for the important signals of support and the positive decisions for both our countries”.

How one man with a hacksaw and an e-bike became a Texas flood ‘hero’

How one man with a hacksaw and an e-bike became a Texas flood 'hero'

Locals call him the “Bicycle hero,” but Texas man Evan Wayne says he’s just doing what he can to help his community after it was cut off due to the recent devastating and deadly flooding tragedy.

When the local Sandy Creek flooded following torrential rains in Texas, it destroyed the only bridge into one community. Residents were cut off from access to supplies, including everything from necessities like food, water, and medicine to basic comforts.

Although the bridge was impassable to cars, volunteers who quickly organized to help the stranded residents found that the damaged bridge could still be traversed on foot. Or in the case of Evan Wayne, it could be covered by an electric bike.

Evan joined hundreds of volunteers who answered the call of grassroots organizers by working together without any official capacity. While many started by hand-pulling garden carts of supplies uphill to reach the stricken community, Evan jury-rigged a trailer to an e-bike and took on as much of the load as he could, helping shuttle much-needed food and gear into the community over hundreds of round-trip journeys.

“This was a dog trailer 48 hours ago. I had a hacksaw, hacked the top off, grabbed some bungee cords, and here we are,” explained Evan in an interview with CBS Austin, while waiting for the next load of gear to be stacked on his trailer.

In the first two days of the operation, he made around 100 round trips each day, shuttling food and water as well as critical rescue supplies. “Right now, I’m waiting on a couple of chainsaws that I’ll bring in for a crew that’s been going at it with handsaws so far.”

In addition to delivering needed supplies, Evan has often found himself moving something even more important: information. “I’ve flagged down medics. I’ve been the guy that goes between Austin EMT and STAR Flight because I’m quicker than cell phones sometimes, people don’t have signal a lot of the time.”

Evan quickly points out that he isn’t the only one helping. “I’ve got an e-bike, but other people are pulling carts. People are walking, people are carrying things. Everyone is doing what they can.” But there’s no doubt that his ability to carry more gear at higher speeds and make hundreds of round-trip journeys so far in and out of the stricken neighborhood has helped impact countless lives.

“This is all volunteers here. They’re just taking it upon themselves to get people where they need to go. I think there’s an umbrella company coming in, taking over tomorrow, but until they get here, people are just taking care of people, which is what you’ve got to do.”

E-bikes proving their worth in emergencies

While many people consider electric bicycles just another form of recreation, they’ve proven to be potent transportation alternatives after natural disasters worldwide.

Not only do their small and efficient batteries make performing hundreds of rescue trips like Evans’ possible, but recharging can be done simply and easily with a solar panel when electricity is out after a disaster. And when gas stations are out of fuel (or simply can’t pump it with the power grid down), e-bikes can keep running while gasoline-powered motorcycles or ATVs run dry.

Electric bicycle batteries have also proven to be a handy source of emergency power after hurricanes and other disasters, often helping owners keep their phones charged up for days to remain in contact with family or rescue services.

While most hope to never need theirs for emergency purposes, electric bicycles have proven their worth in countless disaster scenarios, adding benefits far beyond just alternative transportation, recreation, or fitness riding.

New electric car grants of up to £3,750 aims to drive sales

New electric car grants of up to £3,750 aims to drive sales

The taxpayer is to help drive the switch to non-polluting vehicles through a new grant of up to £3,750, but some of the cheapest electric cars are to be excluded.

The Department for Transport (DfT) said a £650m fund was being made available for the Electric Car Grant, which is due to get into gear from Wednesday.

Users of the scheme – the first of its kind since the last Conservative government scrapped grants for new electric vehicles three years ago – will be able to secure discounts based on the “sustainability” of the car.

It will apply only to vehicles with a list price of £37,000 or below – with only the greenest models eligible for the highest grant.

Buyers of so-called ‘Band two’ vehicles can receive up to £1,500.

The qualification criteria includes a recognition of a vehicle’s carbon footprint from manufacture to showroom so UK-produced EVs, costing less than £37,000, would be expected to qualify for the top grant.

It is understood that Chinese-produced EVs – often the cheapest in the market – would not.

DfT said 33 new electric car models were currently available for less than £30,000.

The government has been encouraged to act as sales of new electric vehicles are struggling to keep pace with what is needed to meet emissions targets.

Challenges include the high prices for electric cars when compared to conventionally powered models.

At the same time, consumer and business budgets have been squeezed since the 2022 cost of living crisis – and households and businesses are continuing to feel the pinch to this day.

Another key concern is the state of the public charging network.

Transport Secretary Heidi Alexander said: “This EV grant will not only allow people to keep more of their hard-earned money – it’ll help our automotive sector seize one of the biggest opportunities of the 21st century.

“And with over 82,000 public charge points now available across the UK, we’ve built the infrastructure families need to make the switch with confidence.”

The Government has pledged to ban the sale of new fully petrol or diesel cars and vans from 2030 but has allowed non-plug in hybrid sales to continue until 2025.

It is hoped the grants will enable the industry to meet and even exceed the current zero emission vehicle mandate.

Under the rules, at least 28% of new cars sold by each manufacturer in the UK this year must be zero emission.

The figure stood at 21.6% during the first half of the year.

The car industry has long complained that it has had to foot a multi-billion pound bill to woo buyers for electric cars through “unsustainable” discounting.

Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders, said the grants sent a “clear signal to consumers that now is the time to switch”.

He went on: “Rapid deployment and availability of this grant over the next few years will help provide the momentum that is essential to take the EV market from just one in four today, to four in five by the end of the decade.”

But the Conservatives questioned whether taxpayers should be footing the bill.

Shadow transport secretary Gareth Bacon said: “Last week, the Office for Budget Responsibility made clear the transition to EVs comes at a cost, and this scheme only adds to it.

“Make no mistake: more tax rises are coming in the autumn.”
