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.

Chevy gets cracking on Cruze EV fleet testing

The Chevrolet Volt hasn't yet gone on sale, but General Motors is looking at ways of expanding its electric vehicle lineup. Chevy, along with partner LG, is employing a group of all-electric cars in the form of the Cruze. The sedans are part of a demonstration fleet which is located in Seoul, South Korea and is being used to provide data in an electric vehicle research project. The goal is to gather information on driving patterns and charging behavior in addition to consumer acceptance.
The Cruze EVs, along with some Daewoo Lacetti Premieres EVs, are the first fleet of full-size electric vehicles and should provide invaluable information for The General. Staying full-size means not sacrificing cargo space, so the battery pack is mounted to the underbody, leaving the trunk area open for plenty recyclable, canvas grocery bags.

January no slump for Chevy Volt this year

The mild winter didn't tank January sales for the Chevy Volt this year. While last month's sales were a lot lower than December's – because January new vehicle sales are almost always lower than December's - the second-gen Volt had a good month. GM sold 996 Chevy Volts last month, an increase of 83.8 percent over the 542 sold last January. In December, 2,114 Volts were sold. The trend wasn't as good over at Nissan, which sold 755 Leafs in January. That's a drop of 29.4 percent compared to the 1,070 sold in January 2015. Given the lower overall sales for the Leaf these days, the drop from December wasn't as bad, with 1,347 Leafs sold in the last month of 2015. What's absolutely amazing is that after over five complete years of sales, the cumulative totals of the Leaf and Volt sales in the US remain almost exactly the same. The current difference is only 600 units, with the Leaf on top. If the Volt continues to outsell the Leaf for the next few months – and all indications are that that is likely, since Nissan is offering the first-gen model while Chevy has put out it much-improved second-gen - then we will soon get back to an equilibrium like we were at the end of February 2015, when the difference was just two units. As always, our more complete wrap up of all the green car sales in the US will be coming soon. Stay tuned. Related Video: News Source: Nissan, GM Green Chevrolet Nissan Electric ev sales
