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.

Mercedes-AMG teases C63 Coupe again, this time on video

The present Mercedes-Benz C-Class has gone mature in the best way. The C63 AMG, however, is a gentleman villain, and it appears that the C63 AMG Coupe could go full rogue. Earlier this month Mercedes teased the two-door and a dash of its aural violence, but only gave us pictures to look at. The second teaser puts bits of the car on camera, accompanied by more of its tamer sound effects. The C63 AMG Coupe will almost certainly be seen in glossy photos beforehand, but we expect to meet the noble barbarian at the Frankfurt Motor Show with a 4.0-liter, twin-turbo V8 underhood. In the C63 S sedan that engine works up 503 horsepower and 516 pound-feet of torque, numbers that should be the same here. It will be joined by its other, less fire-breathing coupe siblings on the show stand. And since this second teaser is so brief, we've included a longer vid captured at the 'Ring in which the coming AMG tries to keep its tail under control. You'll find that below.

Mercedes-Benz pickup could come to US

Mercedes-Benz USA CEO Steve Cannon says the brand has until the end of the year to decide whether to bring its upcoming midsize pickup truck to the United States. "We said to Stuttgart, 'We are open, and let us assess the market.' If that leads to us saying 'green light,' then we will bring it," Cannon said to Automotive News. Mercedes-Benz Vans is leading the pickup's development, and the company's official announcement said the truck's intended markets are Latin America, South Africa, Australia and Europe. The vehicle is expected to launch by 2020. The company might take advantage of some of Nissan's truck expertise on the project, but that's not decided yet, according to Renault-Nissan CEO Carlos Ghosn. However, if the Mercedes pickup makes it to the US, it wouldn't be the same utility-oriented model as for the rest of the world. Instead, Cannon indicates that the truck would be adapted to fill a more luxurious role in the lineup and wouldn't be limited to dealers that sell vans. "For a Mercedes-Benz household that has a lot of stuff or a lot of kids or they want to tow the boat - we could offer something to customers who are already luxury-predisposed," he said to Automotive News. Keep in mind none of this is set in stone, and Mercedes doesn't have to offer the model here because "officially it was approved without US volume," Cannon said to Automotive News. He thinks the truck would be a niche vehicle and sales might only be around 10,000 units a year. With pickups among the leading segments in transactions over $50,000 in the US, the market could still be the right fit for the traditionally high-end German brand. Related Video:
