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.

Jaguar takes evolutionary approach for 2016 XF [w/videos]

One week ahead of its debut at the 2015 New York Auto Show, Jaguar has let loose a slew of images and details on the second-generation 2016 XF Sedan. The release comes alongside a high-profile stunt over London's Canary Wharf. A total of 75 percent of the XF's body is made from aluminum, which trims the big cat's curb weight by 132 pounds on the rear-drive model and 265 pounds on the all-wheel-drive variant. Aside from aiding acceleration, braking and fuel economy, the advanced structure promises an increase in torsional stiffness as well as a 50-50 weight distribution. Beyond that, the new car's dimensions differ only slightly compared to last year's XF. The wheelbase has been stretched by two inches, although the new model is 0.3-inches shorter and 0.1 inches lower. Double wishbones are used in front while an integral-link suspension sits in back with standard traditional dampers and optional adaptive dampers. Jaguar is also promising the Configurable Dynamics system that was pioneered on the F-Type. No surprise here, but an electric power-assisted tiller will be in use, although Jag says it benefits from lessons learned with the XE. Jaguar is mum on its full powertrain lineup, although it does mention that both 340-horsepower and 380-hp versions of Jaguar Land Rover's familiar 3.0-liter, supercharged V6 will be offered, paired with standard eight-speed automatic transmissions (likely the highly regarded ZF autobox). Jaguar's designers, led by design director Ian Callum, didn't rock the boat too much for the new sedan. Clearly inspired by the upcoming XE, the new XF gets a wider, but thinner grille. The headlights are slimmer, but retain a similar shape compared to last year's car, and as is the trend, they're now lined with LED accenting. The S trim, shown above, gets wide, menacing grilles in the front bumper as well as a total lack of chrome trim. The XE influence is most evident on the XF's tail, where the Aston Martin-aping taillights of the first-gen have been ditched, with broader, angled units, complete with an F-Type-inspired LED pattern. As with the current car, a thin chrome strip ties the lights together, while the lower bumper on this sportier model features a gloss black surround for the dual exhausts. Not surprisingly, the XF's profile is pretty classic, with a very long hood and a short deck that terminates in a handsome duckbill spoiler.

Ex-Jaguar design boss Ian Callum starts his own design firm

A month ago, Ian Callum stepped down from his position as Jaguar's director of design. In a 20-year career with the English sports car maker, Callum's pen has traced the lines of everything from the original XK, the XJ, the F-Type, I-Pace, and more. Before that, he made use of employ at Aston Martin by contributing to the original DB7, the DB9, the previous Vantage, and the first Vanquish. After a career in service to OEMs that's been brilliant enough to earn him a CBE, for Commander of the Most Excellent Order of the British Empire, Callum has stepped up to take the reins at his eponymous design firm, called "Callum." Established with four fellow ex-Jaguar executives, Callum will design and engineer bespoke and limited-edition creations in the worlds of art, audio, automotive, fashion, lifestyle, and motorsports. The other trio of founding members are program director David Fairborn, engineering director Adam Donfrancesco, and commercial director Tom Bird. Fairbarn was the head of bespoke and special commissions at Jaguar Land Rover, where he helped bring the Lightweight E-Type to life. Donfrancesco left his role as engineering manager for JLR 's bespoke and special commissions; before that, he developed road and race cars like the Aston Martin GT8 and GT12. Bird, after stints at PWC and Barclays, had been commercial manager at JLR, where he shepherded the C-X75 concept into the James Bond movie Spectre. Callum said of the venture, "I wanted to get back to the essence of creativity; the challenge of producing something wonderful and personal. To design the alternative has always been my mantra, but always the beautiful alternative and something to enjoy." The man's still contracted to Jaguar as a brand ambassador, but at 64 years old, he feels "I've got maybe 15 years of design aptitude left, and I want to make the most of it." With 18 employees and based in a 20,000-square-foot facility in Warwick, the firm is ready right now with the engineering and manufacturing machinery to create products in-house. Even with the company's wide remit, we expect to see Callum take a stand in the automotive space. He admitted that he'd "like to take some of the cars I've designed and maybe redo them a little bit," but the team will always consider the entire vehicle, looking to upgrade dynamics and handling, too. We're told the first project will be announced soon.
