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 plotting E-Class Maybach, next A-Class for the US?

Mercedes-Benz has opened 2015 by hinting at a host of new products. Dieter Zetsche nudged the idea that there'll be a Maybach-branded SUV. AMG chief Tobias Moers told Motor Trend that "We want to be seen by the public on the same level as the other sports car maker in Germany" when asked if his crew was working on a car to rival the Porsche 918 Spyder. That and a few other tidbits have people thinking that we'll eventually see some sort of celestial AMG supercar. The latest handful of hints came from Mercedes USA CEO Steve Cannon during an interview on the marque's move to Atlanta. Cannon told Automotive News that we'd "see more from the Maybach brand," leaving the impression that there "could" be an E-Class draped in the superluxury trim. If such came to pass, there's plenty of pricing room between the E and the S-Class to slot a higher trim in. The top non-AMG E-Class starts at $62,350, the S-Class opens the bidding at $94,400. Even if you slapped the E-Class with the $23,000 premium it takes to make an S600 a Maybach S600, you've still got plenty of breathing room between the midsized and full-sized sedans. At the antipodal end, Cannon told AN that we could get a front-wheel-drive Mercedes smaller than anything here right now. That leaves the A-Class, since we've already got the B-Class. Getting the next-gen A-Class here would help with CAFE numbers, and since it will be built in the new factory in Aguascalientes, Mexico it won't have far to travel to get here. We're told it won't be like the current car, however; Cannon said, "The A-Class will change from what you have seen and from what you are used to." We hope that's a good thing, because we really like the current car. Related Video:
