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.

VW spending $10 million on EV infrastructure, calls on Congress for help

It must be the season of big EV infrastructure announcements. In the last few days, we've heard from Bollore in France, PG&E in California and now VW. The German automaker says it will spend a total of $10 million on electric vehicle charging infrastructure by 2016. That includes the previously announced ChargePoint investment VW made with BMW and work the automaker is doing to get chargers for cars like the e-Golf installed as its dealerships. But Jorg Sommer, Volkswagen of America'sl VP of product marketing and strategy, said today in Washington, DC that automakers need help from the federal, state and local governments to turn electric mobility into a thing. Speaking at the 2015 Electric Drive Congress, Sommer said VW would like the Feds to support fast charging networks in urban areas as well as interstate corridors and that governments should "commit to cleaner fleets by purchasing EVs and PHEVs. This should be a US Government priority," he said. He also suggested that the plug-in vehicle multiplier credits under the EPA's greenhouse gas regulations should be extended beyond the 2021 model year. VOLKSWAGEN OF AMERICA TO INVEST $10 MILLION IN ELECTRIC VEHICLE CHARGING INFRASTRUCTURE BY 2016 Feb 10, 2015 Washington, D.C., February 10, 2015 – Jorg Sommer, vice president, product marketing and strategy, Volkswagen of America, today presented Volkswagen's holistic approach to e-mobility surrounding the launch of the zero-tailpipe emissions 2015 e-Golf, including a $10 million commitment to support electric vehicle infrastructure by 2016. During a presentation delivered at the 2015 Electric Drive Congress in Washington D.C., Sommer stated that Volkswagen believes continued legislative support is needed to reach the next level of electric vehicle adoption. "Automakers have effectively delivered electric vehicles that can satisfy the needs of most American drivers," said Sommer. "In addition to the investment we and other companies and industries are making, we would like to see Federal financing support for establishing fast charging networks in urban areas and interstate corridors. We'd like to see more state and federal organizations commit to cleaner fleets by purchasing EVs and PHEVs. This should be a U.S. Government priority, and federal purchasing guidelines should reflect that by giving fleet purchasers the flexibility they need," Sommer said.

To solve diesel problem, VW might need two fixes

Volkswagen says that a fix is on the way for its 11 million vehicles around the globe that are equipped with diesel engine software that can evade emissions tests. The problem might be far more complicated than simply creating a single solution for all of them, though. According to Automotive News citing Reuters, two remedies to cover different NOx-reducing systems could be necessary, and both potentially affect performance. Earlier examples of the EA 189 diesel engine used a lean NOx trap to reduce the harmful material coming from the tailpipe. According to experts in the Automotive News report, a software update might allow the engines to achieve compliance, but that could affect fuel economy. VW already tried this route once before the scandal came to light, but tests by the California Air Resources Board still showed the figures were too high. Later, some of the 2.0 TDI engines began using Selective Catalytic Reduction that reduced NOx by injecting a urea solution into the exhaust stream. According to Automotive News, a software update for this equipment might increase the amount of the substance used. Not only would that mean topping up the fluid more often, but there still could be some reduction in fuel economy. But, since the 2-liter, 4-cylinder TDI engine that sits inside the diesel vehicles first mentioned as being affected by the issue in the US don't have a urea treatment system, VW would need to install them into these cars. VW still hasn't officially outlined its solution (or solutions) to the emissions issue but is expected to soon. The automaker's long-term evasion of regulations with these diesel engines pumped vast quantities of additional NOx into the air. The substance is known to be linked with smog and acid rain. The US Department of Justice is already beginning an investigation into the company, and politicians are pushing for harsh punishments.
