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 picks Gensler to design new Atlanta HQ

Mercedes is planning to move of its US headquarters from Montvale, NJ, to Atlanta, GA – and with over a thousand employees to house, the project will surely be massive. In order to pull it off, the automaker is going to need the right architects. And Mercedes seems convinced that Gensler is the way to go. Never heard of Gensler? The San Francisco-based architectural giant (incorporated as M. Arthur Gensler Jr. & Associates, Inc.) has done the headquarters for Facebook, Coca-Cola and General Electric. It designed the Shanghai Tower, the tallest building in China, and crafted the master plan for the Olympic Games set to take place in Rio de Janeiro next year. It's done hotels, sports arenas, military facilities, airport terminals... the works. It also redesigned Cadillac's showrooms and Hyundai's new US headquarters, and among the many offices it operates in 46 cities and 16 countries around the world, it has a branch in Atlanta. So of the dozen firms Mercedes considered for the task, Gensler got the nod. The 250,000-square-foot facility is earmarked for completion in 2018, occupying a 12-acre plot at the corner of Abernathy and Barfield roads in Sandy Springs, Georgia. In the meantime, MBUSA is preparing to move temporarily from its current offices (pictured here) in Jersey down to another facility in the Atlanta area, also being set up by Gensler, in nearby Dunwoody – just a couple of miles down the road from where the permanent site will be. Mercedes-Benz USA Selects Gensler As Architect For New Atlanta Headquarters Facility Award-winning global firm to design 250,000-sq-ft office building in Sandy Springs, GA April 30, 2015 - MONTVALE, N.J. Mercedes-Benz USA (MBUSA) today announced it has selected Gensler as the architecture firm for its new headquarters facility in metro Atlanta. Gensler will design an approximately 250,000-square-foot office building that will house around 1,000 MBUSA employees upon its completion in 2018. "We talked to many, many firms and saw some amazing designs, but Gensler was the one that stood out for us," said MBUSA President and CEO Stephen Cannon. "They understood our brand and our culture, along with the ambitious goals we have for the next chapter of Mercedes-Benz in this market, and they were able bring that to life in their designs." MBUSA selected Gensler from a dozen global design firms for its creative building concept, which seamlessly integrates functionality and the beautiful surrounding landscape.

Race recap: 2016 Australian F1 Grand Prix a rowdy start to season

The three brief Formula 1 tests ahead of the current season belied how much had gone on since the last race in November: Infiniti subbed out for Tag Heuer, Renault is back, the all new Haas F1 team, a revamped Manor, three brand new drivers and two returning drivers, a raft of regulation changes among the newly tilled soil. The four engine manufacturers spent a combined 67 tokens among the 138 in the kitty, Renault using just seven of their 32. The only conclusive proof to come from the annual intermission was the otherworldly capability of Mercedes-AMG Petronas. The Silver Arrows didn't even try the super- and ultra-soft tires, focusing on reliability instead of speed. The result? They ran more than 19 race distances, obliterating the lap totals of every other team. There are certainly a few people who enjoyed the complicated new rolling-elimination qualifying format fast-tracked to approval just a few weeks ago. They were wildly outnumbered by those who thought it was awful, including the same team heads who voted for it. We'd probably have to go back to the debacle at the 2005 Indianapolis Grand Prix for an equivalent fiasco when Michelin pulled its teams over safety fears, leaving six cars out of 20 to qualify. In Australia, within 24 hours of the conclusion of qualifying, the new format had itself been eliminated. Nevertheless, qualifying also taught us what didn't happen over the winter: any other team progressing enough to outduel Mercedes. After admitting that he dropped off after winning the championship last year, then getting questioned in the press for some dubious off-season activities, Lewis Hamilton proved he can still turn it on when he wants to. The Brit smoked the Albert Park track in 1:23.837, more than three-tenths of a second ahead of teammate Nico Rosberg in second place. Ferrari did make strides during the off-season, but only enough to keep the same gap it had to Mercedes last year: Sebastian Vettel lined up third, a half-second behind Rosberg, teammate Kimi Raikkonen another four-tenths back in fourth place. Max Verstappen said Toro Rosso is the best of the rest, the Dutchman taking fifth place in front of Felipe Massa for Williams in sixth and Toro Rosso teammate Carlos Sainz in sixth. Daniel Ricciardo – who wasn't smiling after qualifying – kept Red Bull and its new "Tag Heuer" engines in the conversation with eighth on the grid.
