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.

German automakers' stocks fall as EU investigates collusion

BERLIN/FRANKFURT - Volkswagen will hold a special supervisory board meeting on Wednesday to discuss allegations that German carmakers operated a wide-ranging cartel, a source familiar with the matter said on Monday. The European Commission said on Saturday antitrust regulators were investigating a possible German auto industry cartel following a tipoff. At stake is whether carmakers VW, Audi, Porsche, Mercedes and BMW used German auto industry committees to discuss pricing of components and technologies, and whether such talks constituted anti-competitive behavior. A VW spokesman confirmed an extraordinary supervisory board meeting would be held on Wednesday but declined to give details. German auto stocks took a hit in early trading on Monday, weighed down by uncertainty over possible antitrust fines after European regulators said they were probing cartel allegations. VW shares were down 2.8 percent, with Daimler and BMW down 3.4 percent and 2.5 percent respectively, lagging the blue-chip DAX index, which was 0.7 percent lower. Exane BNP Paribas automotive analyst Stuart Pearson said little was known about the allegations, but no signs had emerged about fixing prices charged to consumers. "More ugly details could yet emerge, leaving German manufacturers - and the EU auto sector - still firmly in the sin bin for now," he added. The car industry has been hit with billion-euro fines on both sides of the Atlantic in recent years for cartels related to various parts such as lighting systems, engine coolers and bearings. The industry's record on exhaust emissions is also under close scrutiny after VW admitted in September 2015 to cheating U.S. diesel emissions tests and investigations have shown many vehicles exceeding pollution limits outside of testing labs. On Friday, German magazine Der Spiegel said VW, its Audi and Porsche brands, Mercedes-owner Daimler and BMW may have colluded to fix prices on components, including of diesel emissions treatment systems, using industry committees. Spiegel said the talks also led to the use of smaller tanks containing AdBlue, a urea-based liquid needed to help filter nitrogen oxides (NOx) from diesel emissions. Larger tanks would have been more expensive, the magazine said. Auto industry experts, however, have said the effectiveness of exhaust filtering systems does not depend on the size of an AdBlue Tank. BMW, for example, has equipped its cars with urea injection as well as a NOx-storage catalytic converter.

Mercedes-Maybach Ultimate Luxury fully revealed, tea set and all

Mercedes has officially unveiled its Mercedes-Maybach Ultimate Luxury concept following a leak of most of the details last week. As we learned last week, the unusual looking sedan-SUV crossbreed is fully electric with four motors producing a whopping 750 horsepower. Combined with an 80 kWh battery, Mercedes estimates it should have a range of over 200 miles on the European test cycle. It also can handle extremely fast charging from DC chargers outputting 350 kW. Mercedes claims this allows it to gain 60 miles of range in 5 minutes. But there are a number of interesting details that weren't leaked. Many of them have to do with the car's Chinese inspiration, which is perhaps not that surprising for a car that makes its debut in China. The body style is the first influence, which Mercedes says combines the sedan and SUV, the best-selling car classes in the country. On the inside, there are a pair of cues inspired by China. The first is the ebony wood trim that Mercedes calls "Magic Wood." The company says it's very similar to that used in Chinese furniture. In the back, between the two highly adjustable white leather seats with rose-gold stitching, is a complete tea set. And not only does it contain all the containers for tea, but it actually has a variety of teas on offer. They're there to be used in conjunction with the car's relaxation modes that combine lighting, music and scents to set the mood. It's hard to say whether this concept will spawn a production model, since the body style is unlike any currently offered by Mercedes-Benz. But with the crossover SUV market staying hot, and competitors such as Audi and BMW bringing out extra-large SUVs, we wouldn't be surprised if Mercedes eventually offers at least a Maybach-level version of its GLS-Class, if not its own model.
