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.

New safety and connected features help distinguish VW's lineup

Volkswagen may have wrested the title of world's largest carmaker away from Toyota this week, but the company still has some work to do in the United States. Despite its worldwide dominance, Volkswagen's American sales have languished. Unlike its red-hot Audi brand, mainstream Volkswagen sales have been afflicted by an assortment of maladies. An aging lineup, a reputation for mechanical gremlins and a lack of a competitive crossover vehicle have all hurt. In the US, the brand's cars claim only two percent of the overall market. As we reported earlier today, Volkswagen took steps this week to upgrade some broader aspects of its weaknesses here. At its Electronics Research Laboratory in Silicon Valley, the company announced it would make several advanced safety features and connectivity options available throughout the bulk of its lineup. Features that have long been available on its premium Audi cars will spread to its more economical offerings. In one big way, they will overstep their premium siblings. Volkswagen said Apple CarPlay, Android Auto (pictured below) and MirrorLink will all be available on a revamped infotainment system. Cars equipped with the new Car-Net-branded systems are arriving in showrooms now. Only last month, Hyundai became the first to offer CarPlay, debuting the smartphone-projection system in its 2015 Sonata. Chevy, Honda, and now Volkswagen, have quickly followed suit. On the safety-minded side, features like adaptive cruise control, forward collision warning, autonomous emergency braking, park steering assist and automatic post-collision braking will be optional equipment on most of the brand's 2016 model-year cars. Previously, the features had only been available on the Touareg SUV. They're now available on most Golf variants, the CC, Jetta, Sportwagen and some Beetles. Though the Passat sedan is one of the company's most competitive cars, it was curiously absent from the announcements, though an update could come later this year. While the advanced safety equipment is a boon for motorists increasingly interested in the technology, Volkswagen also added some basic safety tech that's long been available in mainstream competitors' cars, adding features like blind-spot monitoring and lane-departure warning. One of the big differences consumers might note is the cost of the driver-assistance systems.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.
