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.

Watch this time-lapse build of the Chevy SS for NASCAR

There's only about a week left until we get our first look at the production version of the 2014 Chevrolet SS sedan, but Chevrolet NASCAR teams have been looking at the race version of the car all winter. Autoweek has posted a really neat time-lapse video showing just a portion of what it takes to build one of NASCAR's new Gen6 stock cars.
Though the video is quite brief, it does show almost the entire build process starting with just the car's nose, and it gives us a good look at how integral the template is to the final product. As a bonus, Hendrick Motorsports also provided some videos showing two of its teams performing pit stop tests over the winter. The second video shows some of the more detailed aspects of the racecar's rear end, including the stock-looking trunk cutout and a newly mandated rear bumper extension that will be used on super speedways like Daytona and Talladega.
To see what Team Chevy has been up to all off-season, check out all three videos posted after the jump.

GM workers in Oshawa walk out in protest of plant closure

TORONTO/MONTREAL – Canadian Prime Minister Justin Trudeau on Monday expressed his "deep disappointment" in General Motors' decision to close its Oshawa plant, a move Canadian officials only learned about on Sunday and which led workers to walk off the job on Monday. GM said the closure affects a total of 2,973 assembly line jobs. GM's total employment in Canada is 8,150 direct jobs. Workers in the Unifor trade union walked out of the Oshawa plant "in protest," ahead of a meeting with GM about the announcement, a union spokeswoman said. "I've moved my family twice for this company and they do this to me," a tearful worker told CBC TV as he left the plant. Currently, the Oshawa plant builds the Cadillac XTS and Chevy Impala sedans. Under Unifor's four-year contract signed in 2016, GM must give the union a year's notice before closing the plant. The automaker intends to close the plant in December, 2019. A 2015 study commissioned by Unifor, which represents GM employees, estimated that shutting the plant would eliminate 4,100 direct jobs and reduce Ontario's gross domestic product by C$1.1 billion. But Jerry Dias, president of Unifor, said the move amounts to a breach of the automaker's contract with its employees. "We have a collective agreement that says they're not closing any of our facilities ... so we will do anything by any means to make sure that they live up to their word," Dias said at a news conference. Dias said the contract between Unifor and the company forbids GM from closing any of its Canadian plants during the contract period, which ends in September 2020. "They are not closing our damn plant without one hell of a fight." Canadian officials promised to aid auto workers affected by the 2019 closure, part of a wider restructuring by the automaker that will cut production of slow-selling models and slash its North American workforce. "I spoke with GM (CEO) Mary Barra to express my deep disappointment in the closure," Trudeau tweeted on Monday. "We'll do everything we can to help the families affected by this news get back on their feet." GM workers have been part of the heart and soul of Oshawa for generations - and we'll do everything we can to help the families affected by this news get back on their feet. Yesterday, I spoke with @GM's Mary Barra to express my deep disappointment in the closure.
