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.

Race Recap: 2015 Canadian F1 Grand Prix is better behind the front

As of Saturday afternoon in Montreal, Canada, it was all about the number four. Lewis Hamilton put his Mercedes-AMG Petronas on pole position for the fourth time at the Circuit Gilles Villeneuve, and now his tally of pole positions matches his race number: 44. Nico Rosberg lines up beside him, which is the fourth time that particular one-two combo has occurred this season. Ferrari spent three engine development tokens to try and close the gap to Mercedes, Kimi Raikkonen making the most of it with third position on the gird. His teammate Sebastian Vettel got the worst of it, however, when the MGU-K unit failed during Q1, leaving him 160 horsepower down and out at the first hurdle. Valtteri Bottas put a revitalized Williams on the grid at fourth, ahead of a Lotus lockout of the third row with Romain Grosjean leading the way in fifth, Pastor Maldonado just beside. Nico Hulkenberg got the first Sahara Force India into seventh – the team is still waiting on the upgraded B car that should be available for Austria – ahead of Daniil Kvyat in the first Infiniti Red Bull Racing and a "pissed off" Daniel Ricciardo in the second Red Bull. Sergio Perez made it two Force Indias in the top ten, a welcome result from a team performing below expectations of late. When the lights went out, at the very front it was much ado about not that much at all. Hamilton got away clean and stabbed across the track to close the door for Rosberg, giving Raikkonen a chance to take the inside line into Turn 1 in an attempt to clear Rosberg for second place. That didn't happen, leaving the two Mercedes' to run in grid position for the entire race. It wasn't boring – Rosberg stayed close, rubber-banding the time gap to the leader from a little more than one second to just under four seconds, and Montreal is famous for race-rearranging safety cars and on-track incidents. But none of those occurred, so Hamilton crossed the line 2.285 seconds ahead of Rosberg after 70 laps to earn his fourth victory in Canada and the first-ever victory for the Brackley, UK-based Mercedes team. Valtteri Bottas drove his Williams to third position, the first podium place for the team this year and a welcome salve to heal the team's wounds from a poor showing in Monaco. That placing came courtesy of being in the right place at the right time, which was not far behind Raikkonen when the Ferrari driver spun at the hairpin on Lap 28 after his first pit stop.

Mercedes calling in CLS, E-Class over rubber seal fire risk

Mercedes-Benz has discovered a problem with certain E-Class and CLS-Class models and has notified the National Highway Traffic Safety Administration of a recall it's undertaking to resolve the issue. The problem is with the rubber seal at the back of the engine bay, which according to the statement below "may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed." If it then comes into contact with the exhaust system, it could start a fire. And fires in the engine bay are never a good thing, unless they're contained entirely within the combustion chamber. The issue affects an estimated total of 147,224 E-Class and CLS-Class vehicles, all told, across America – including four-doors, wagons, hybrids and AMG performance models (but no E-Class coupes or convertibles) from the 2013-15 model years. To fix the problem, Benz dealers will simply need to attach four additional clips to keep the seal in place, and will start doing so midway through next month. RECALL Subject : Rubber Seal may Dislodge and Contact Exhaust Report Receipt Date: FEB 13, 2015 NHTSA Campaign Number: 15V088000 Component(s): STRUCTURE Potential Number of Units Affected: 147,224 Manufacturer: Mercedes-Benz USA, LLC. SUMMARY: Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2013-2015 E350 Sedan, E350 4Matic Sedan, E350 4Matic Station Wagon, E400 Hybrid Sedan, CLS 550 CGI, and CLS550 4Matic, 2013-2014 E550 4Matic Sedan, 2013 E63 Sedan, E63 Station Wagon and CLS63, 2014-2015 CLS63 4Matic, E63 4Matic Sedan, E63 4Matic Sedan "S", and E63 4Matic Station Wagon, 2015 CLS400, 2015 E400 Sedan, E400 4Matic Sedan and CLS400 4Matic and 2014 CLS63 "S". The affected vehicles have a rubber seal at the back of the engine bay that may temporarily stick to the hood when it is opened and then may fall into the engine bay when the hood is closed. CONSEQUENCE: If the rubber seal falls into the engine compartment, it may contact parts of the exhaust system, increasing the risk of a fire. REMEDY: MBUSA will notify owners, and dealers will attach four additional retaining clips to the rubber seal, free of charge. The recall is expected to begin by mid-March 2015. Owners may contact MBUSA customer service at 1-201-573-5339. MBUSA's number for this recall is 2015020001. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
