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.

Recharge Wrap-up: BMW i8's Engine of the Year, biodiesel producer guilty

BMW has won International Engine of the Year for the hybrid system in the i8. The i8 PHEV uses a 1.5-liter, three-cylinder gasoline engine with a hybrid drive unit including a 96-kilowatt electric motor. BMW beat Ford's 1.0-liter EcoBoost engine by a small margin to win the award for best overall engine. It also took the award for the 1.4-liter to 1.8-liter category, as well as best new engine. Tesla beat BMW to win the green engine category for the electric powertrain of the Tesla Model S.

The head of Audi powertain development is quitting as the automaker steps up electrification. Stefan Knirsch has worked at Audi since late 2013, and previously worked at Porsche as the head of quality management and engine development. Germany's Auto Motor und Sport magazine had reported that Knirsch was leaving Audi, which Audi confirmed without giving a departure date or saying if he would be working elsewhere. Audi has been feeling pressure from its competitor Mercedes-Benz, and has been working on improving its EV offerings and autonomous vehicle technology. Read more from Reuters. The owner of a biodiesel company has pleaded guilty to fraud. Philip Joseph Rivkin, aka Felipe Poitan Arriaga, took part in a scheme to defraud the EPA, falsely claiming to be producing millions of gallons of biodiesel. This allowed his company, Green Diesel, to receive renewable fuel credits and sell them to oil companies and brokers. "These crimes are a serious threat to an important program that helps combat climate change," says Cynthia Giles of the EPA. "Companies and individual managers should get the message that there are serious consequences for breaking the rules and undermining the integrity of this program." Rivkin faces over 10 years in prison and $51 million in restitution. Read more in the press release below. Biodiesel Fuel Company Owner Pleads Guilty to Fraud and Clean Air Act Crimes Connected to Renewable Fuels Scheme Philip J. Rivkin faces more than 10 years imprisonment and $51 million in restitution WASHINGTON – Philip Joseph Rivkin, a.k.a. Felipe Poitan Arriaga, 50, today pleaded guilty to a Clean Air Act false statement and mail fraud as part of his role in a scheme to defraud EPA by falsely representing that he was producing millions of gallons of biodiesel fuel.

2015 Mercedes-Benz CLS400 [w/video]

Rocky IV debuted in 1985 but it was a few years later that I first watched it, on video. I loved every second of that terrible movie. I loved Drago's super-high-tech demonstration of punching power. I loved Rocky training in a Russian barn, with ropes, and yokes, and wagons. But mostly I loved Brigitte Nielsen. My 10-year-old brain sweated her impossible combination of curves and sharp edges, demure eyes, and sculpted bone structure. The perfect woman, but evolved by the power of the dark-hearted Soviet Union (or Denmark, whatever, I was ten). Red Sonja has a lot in common with the latest version of the Mercedes-Benz CLS, as I see it. Mercedes created a new market niche with its first four-door coupe, a sedan so well-proportioned, flowing, and femininely curved that it could pull off its inaccurate moniker. The third evolution of the CLS you see here has Nielsened up the shape into something altogether more angular and edgy, but like 1985's Brigitte, retains an undeniable sex appeal. It's a more opinionated piece of auto design than was the original CLS. And also a car that bifurcates the space between luxury coupe and luxury sedan. Ludmilla Drago would undoubtedly understand. Driving Notes For the base engine of a 4,200-pound car, the CLS400's two-turbo V6 does better than just get out of its own way. The full 354 pound-feet of torque is available way down at 1,600 revs, and plateaus until 4,000, giving you a fat band in which to call up power. Acceleration is available in the form of a quiet, gracious, but not aggressive push at just about every speed. From inside the cabin, the engine and exhaust noises are pleasantly rumbling, though muted. But do yourself a favor and try not to listen to the CLS tick over while standing around the driveway. When the car first pulled up in mine, warm from some 40 miles of highway, it still sounded an awful lot like a 2.0T on a mid-March morning. Not to belabor the Brigitte metaphor, but I found as much Neilsenian dichotomy in the ride and handling as I did the exterior styling. Especially with Mercedes' 4Matic system spreading out the grip, I found the CLS to be sharp when pushed, and rather excellent in terms of making quick corrections while under a cornering load. And yet, you've got to push through an initially soft suspension response to reach that hard edge. The CLS will initially resist being tossed around a winding backroad, but press on and she'll do as you ask.
