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.

2016 Mercedes-Benz GLC300 4Matic Quick Spin [w/video]

Mercedes-Benz product guru Bart Herring strode to the middle of a crowded conference room in Atlanta and succinctly explained the 2016 GLC. "What's different from the outgoing car? Everything." That's getting right to the point, and it's accurate. The GLC is lighter, larger, and more comfortable than the long-running GLK that it replaces. It's wrapped in a simple yet elegant design that's a departure from the polarizing looks of its off-road-themed predecessor, and the "C" in the name now clearly aligns it as the SUV counterpart to the C-Class sedan. We'll always have a soft spot for the GLK, but the widespread appeal of the GLC is undeniable. Driving Notes The GLC300 runs Mercedes' widely used 2.0-liter turbocharged four-cylinder, rated at 241 horsepower and 273 pound-feet of torque. Maximum twist is served up at just 1,300 rpm, which makes passing smooth and easy. We pick off semis and slower moving traffic with confidence. During these bursts of acceleration, we notice the engine note, which has a deep timbre. The turbo four is a solid replacement for the GLK's naturally aspirated V6. Still, we like that engine. It serves up 302 hp in no-frills fashion. But Mercedes is moving away from six cylinders, inline with market trends, and this turbo delivers 20-percent better fuel economy. Though the I4 and V6 are both rated at 273 lb-ft, the turbo's max output is available much sooner. Coupled with the lighter weight, it almost makes up for the turbo four's 61 fewer hp. 0-60 times are expected to be comparable, Herring says. The GLC's nine-speed automatic transmission replaces the GLK's seven-speed auto gearbox. The new transmission shifts smoothly when we're cruising, though it will hold gears longer in Sport and Sport+ modes when we want to spice things up. We pull the paddles during acceleration, but found this sophisticated unit is best left to its own devices. We spend most of our test in a 4Matic all-wheel-drive version, which provides a little extra peace of mind on a chilly, wet morning as we navigate the busy highways and quiet rural routes of northern Georgia. Generally, it's hard to actually test all-wheel-drive capability on the street, but we definitely notice when we don't have it. During our brief test in a rear-drive model, the tires spin when we get on the throttle aggressively, and the vehicle feels a little more unbuttoned over the wet leaves strewn across the damp pavement.

Mercedes-Benz GLA Concept crossover leaked ahead of Shanghai debut

With just a few days left before the start of the Shanghai Motor Show, images of the Mercedes-Benz GLA Concept compact crossover have emerged online. The little 'ute is based on the small A-Class hatchback, and though it shares an identical wheelbase, is larger in every other dimension.
Looking like a rough-and-tumble five-door hatchback on the tippy toes of its 20-inch wheels, the GLA is most certainly destined for production in a toned down form that will borrow many bits and pieces from other cars based on this platform like the aforementioned A-Class and the CLA-Class sedan. Carscoop reports that the production version of the GLA will be revealed at the Frankfurt Motor Show in September of this year, with sales to the public starting in 2014.
Since it's based on the A-Class, we expect that the production GLA-Class will be powered by your choice of Mercedes' 2.0-liter turbocharged inline four-cylinder engine and a diesel or two, and will offer transmissions that include the company's seven-speed DCT and perhaps a six-speed manual (at least in Europe). If the GLA follows the same path as the two cars before it, expect a GLA45 AMG producing over 300 horsepower, as well. As for what powers the GLA Concept, that just might remain a mystery until the vehicle is officially revealed in China.
