Weekly Recap: The divergent paths of Tesla and Fisker

There's no doubt that Tesla is downshifting while Fisker has been grinding its gears. But it wasn't always that way.
In the wake of Tesla's recent success, it's easy to forget that there were once two California electric carmakers with bright futures.

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.

Watch the next BMW M5 slide its way around the Nurburgring

By now, you've probably seen the spy photos of the next BMW M5 – we posted three sets of camouflaged cars last year. Now comes recently captured video showing three camouflaged examples – including the car shown in our June 2015 photos – lapping Germany's famed Nurburgring. The (obvious) advantage of video when looking at prototypes like this is that we can actually see the vehicle in motion. That allows us to make a couple of educated guesses, particularly when it comes to the rumors about the next M5 moving to an all-wheel-drive setup. In the video, we can clearly see the next super-sedan throw its tail out around a bend. Judging by the way the driver takes the turn and the change in engine note, it looks and sounds like the driver was actively trying to throw the tail out. That could point to a rear-drive layout, or at the very least an AWD setup with a heavy rear-wheel bias. Beyond seeing the M5 sliding about, we also get to hear its thumping, twin-turbo heart at work. It's widely expected BMW's popular 4.4-liter, twin-turbo V8 will carry on under the hood, and this video gives us absolutely zero reason to think otherwise. It sounds a lot like the current car, down to the abrupt upshifts of the seven-speed, dual-clutch transmission. According to the video's caption, that upgraded V8 should get around a 60-horsepower bump, which would put it around 620 hp. That's 20 ponies more than the 30th Anniversary car and would contradict a June 2015 report claiming that M was capping its cars at 600 hp. Related Video:
