Here’s how 20 popular EVs fared in cold-weather testing in Norway

Electric vehicles are known to suffer diminished performance in cold weather, but some do a better job than others hanging onto their range capacity while cabin heaters and frigid outdoor temperatures sap power from their batteries. Recently, the Norwegian Automobile Federation put the 20 of the best-selling battery-electric vehicles in the country to the test, to see not only how winter weather affected their range but also their charging times. The major findings: On average, electric vehicles lost 18.5% of their official driving range as determined by the European WLTP cycle. Electric vehicles also charge more slowly in cold temperatures. And interestingly, the researchers learned that EVs don’t simply shut down when they lose power but instead deliver a series of warnings to the driver, with driving comfort and speed levels maintained until the very last few miles. Because itÂ’s Norway, the worldÂ’s top market for electric and plug-in hybrid vehicles by market share, the test included many EVs that arenÂ’t available here in the U.S. But there are many familiar faces, among them the Nissan Leaf, Tesla Models S, 3 and X, Hyundai Kona (known here as the Kona Electric) and Ioniq, and Audi E-Tron. In terms of range, the top-performing EV was the Hyundai Kona, which lost only 9% of its official range, which the WTLP rated at 449 kilometers, or 279 miles, compared to its EPA-rated range of 258 miles on a full charge. It delivered 405 km, just enough to nudge it ahead of the Tesla Model 3, which returned 404 km. Other top performers included the Audi E-Tron, in both its 50 Quattro (13% lower range) and higher-powered 55 Quattro (14% lower) guises; the Hyundai Ioniq (10% lower); and Volkswagen e-Golf (11% lower). At 610 km (379 miles) the Tesla Model S has the longest WLTP range of all models tested and went the furthest, but still lost 23% of its range, though it also encountered energy-sapping heavy snow at the end of its test, when many cars had dropped out. The Model 3 lost 28% of its range. The worst performer? That goes to the Opel Ampera-e, better known stateside as the Chevrolet Bolt. It traveled 297 km (about 184 miles) in the test, which was nearly 30% lower than its stated WLTP range. We should also note that Opel, now owned by Groupe PSA, is phasing the car out in Europe and that Chevy recently upgraded the Bolt here in the U.S.

The real reason Audi races

The world has watched Audi have its way with endurance racing since 1998. What started as an intriguing race winner in 2000 that could be rebuilt so quickly that the ACO oversight organization changed the rules to slow Audi mechanics down, slowly morphed into a unique assassin, employing novel engineering methods to achieve series domination with its R18 E-Tron Quattro. Until recently. It's strange, then, that for all these years we didn't fully comprehend Audi's stated approach to motorsport. And so we sat down with Dr. Wolfgang Ulrich, head of Audi Motorsport, and Chris Reinke, head of Le Mans Prototype development while in Austin, TX, for the Lone Star Le Mans and World Endurance Championship race for answers. BMW, Corvette, Porsche, and Ferrari have healthy reputations, lucrative option sheets, and supported a robust trade in special editions by winning races. They have standalone racing divisions and they transfer the entire sheen of their racing endeavors to their road cars, a healthy part of what their customers buy into. Even though we know they improve their road cars with lessons learned racing, the belief is that they race because that's just what they do; those brand names mean racing. "Not one single euro is spent on a separate motorsports program." Yet Reinke said that for Audi, "Not one single euro is spent on a separate motorsports program. We [Audi Motorsport] are part of the Technical Department [of the road car company]. We are a pre-development lab for road-relevant technology." As in, Audi isn't racing out of core philosophy, it's racing only to improve its road cars. That helps explain why Audi's entire road car lineup doesn't bask in the same racing aura as those other brands even though Audi has been racing since it was called Horch. It's not a racing brand, it's a technology brand. Said Ulrich, "Instead of components, look at technologies – not lights, but lighting technologies, not engines, but engine technologies, like injection pressure technology is the same from the race car to the road car." That's nowhere near as exciting as, "Win on Sunday, sell on Monday," but it is arguably much more practical. Quattro is the most obvious example of racing tech for the street. For a less obvious one, Reinke said, "Audi Motorsport developed codes for computational fluid dynamics, and then we'd run the calculations on the Technical Department computers at night.

Audi replaces Mercedes as official vehicle supplier to the IOC

The automotive sponsor of the International Olympic Committee for the past 22 years has been Daimler-Benz. No more, as Audi has just signed a four-year deal to be the official auto supplier to the folks who keep the torch alight and on the move. Audi will supply vehicles for the IOC's headquarters in Lausanne, Switzerland and the organization's international events.
In case you're remembering all the stories about BMW and the London Olympics last summer and wondering where Mercedes-Benz was in all of that, the answer lies in the numerous mouths at the Olympic trough. The IOC is the organization and oversight body of the Olympics - much like the way the FIA oversees world motorsport. BMW, though, sponsored the London Organizing Committee for the Olympic Games, so during the games IOC reps rode in Benzes, LOCOG and its guest dignitaries rode in BMWs.
The Volkswagen Group has other ties with the Olympics as well: The Group will be the official vehicle partner for the winter Olympics in Sochi, Russia in 2014, and Audi currently partners the national Olympic federations of Germany, Finland, Russia and Switzerland. The press release below announcing the partnership has all the official details.
