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.

Mercedes mulling Renault-based entry-level X-Class?

Somewhere in between the Smart brand and the all-new A-Class (pictured above), Daimler is said to be readying a smaller entry-level product for the Mercedes-Benz brand to compete with models like the Audi A1. According to AutoBild, Mercedes-Benz will get a new hatchback based on a platform from its recent partnership with Renault-Nissan, and it could be called the X-Class.
Expected to debut by 2018, the Mercedes-Benz X-Class could be offered in sedan, hatchback and crossover variants, and it would likely have a starting price below the $20,000-euro mark. Power would come from either a 1.0-liter inline three-cylinder engine or a 1.5-liter inline-four, and the car would likely be built in a low-cost nation in order to make the financials work. Wearing the Mercedes-Benz name, the X-Class would have to exhibit more distinguishable luxury and styling to set itself apart from the models that helped provide its underpinnings.

Lewis Hamilton owns 15 cars, uses tow trucks to keep the mileage low

No matter how you feel about Lewis Hamilton off the track, it's impossible not to respect his talent behind the wheel. Currently, Hamilton is the second most successful Formula One driver of all time. His 67 wins and four championships place him only behind Michael Schumacher's 91 wins and seven championships. With all those winnings, Hamilton has racked up a decent personal fortune, much of which he uses to buy cars. Except he doesn't drive them quite as much as you might think. According to The Sunday Times, Hamilton's net worth of just over $207 million makes him one of the richest sports figures in the UK, just behind David Beckham. In a recent interview with the British newspaper, Hamilton gave some details on his personal car collection. His first car was a used Mini Cooper, soon followed by a Mercedes-Benz C200. Both have long since been replaced by a pair of original Shelby Cobras, a 1967 Shelby GT500, a Ferrari 599 SA Aperta, two LaFerraris (a red coupe and a white Aperta), a McLaren P1 and a Pagani Zonda 760 equipped with a manual transmission. All in, Hamilton has about 15 cars split between homes in Monaco and Los Angeles. Unsurprisingly, he has a Mercedes-AMG Project One ( a car that shares more than a little with his F1 W09 EQ Power+ race car) on the way. Hamilton has some hot takes on his personal collection. "The Zonda is terrible to drive," he said. "It's the best-sounding car I own, but handling-wise it's the worst. I got it in manual because I didn't like the tiptronic version. The tiptronic Pagani offered was worse than the Smart Roadster I had." He also says his Shelby Mustang is a "beautiful car, but a heap of junk." In order to keep the miles down (and valuations up), Hamilton apparently has a tow truck on retainer in Los Angeles. When he's finished driving one of his Ferraris, he'll have the car towed back to his place. Classic cars are becoming a solid and serious investment, and Hamilton doesn't want to squander his wealth like some other athletes. That said, there are a couple more cars Hamilton would love to own, including a Mercedes-Benz 300 SL (the one with the gullwing doors) and a Ferrari 250GT California Spyder (the one from "Ferris Bueller's Day Off").
