VW decides against active-cooling system for e-Golf lithium battery

When the 2015 VW e-Golf was introduced at the LA Auto Show last year, VW said it would come with a water-cooled battery. During the Detroit Auto Show, when the car was trotted out again, VW released a new press release that stripped out the "water-cooled" language, but this change went unnoticed. During a recent VW event in Germany, a friend from Green Car Reports realized that the battery on display did not seem to have any water-cooling mechanisms. That set us off on a bit of a sleuthing and we have now learned that VW is not going to include any active cooling in the upcoming e-Golf. In fact, the company is entirely confident that this car - because of what it's designed to do - doesn't need it. "The need for a cooling system wasn't there" - VW's Darryll Harrison VW has been working on an electrified Golf for ages now, and so changes to the plan are to be expected. But battery cooling is vitally important not just to keep the car operating properly but because when things get too hot, there can be serious public relations problems. Nissan began testing a new battery chemistry for the Leaf in 2013 after an uproar from warm-weather EV drivers in Arizona who were experiencing worse-than-expected battery performance. The Leaf has always used an air-cooled battery, which is another way to say that there is no active cooling system (more details here). Tesla CEO Elon Musk once said this approach is "primitive." So, why is VW following the same path? We asked Darryll Harrison, VW US's manager of brand public relations west, for more information, and he told AutoblogGreen that VW engineers discovered through a lot of testing of the Golf Mk6 EV prototypes, that battery performance was not impacted by temperatures when using the right battery chemistry. That chemistry, it turns out, is lithium nickel manganese cobalt oxide (NMC) in cells from Panasonic. These cells had "the lowest self-warming tendency and the lowest memory effect of all cells tested," Harrison said. He added that VW engineers tested the NMC cells in places like Death Valley and Arizona and found they didn't warm very quickly either through operation, charging (including during fast charging) or through high ambient temps. "The need for a cooling system wasn't there," Harrison said.

BMW names new CEO, chairman and head of development

Big changes are afoot in the top ranks at BMW, as the Bavarian automaker has announced not just one, but several appointments in the top floors of its towering headquarters in Munich in what the company itself is referring as "a generational change" in its leadership. The biggest change relates to the chairman of BMW's management board – German-speak for the company's chief executive officer. Effective at the end of the company's Annual General Meeting on May 13, 2015, the company will be run by Harald Kruger. The 49-year-old mechanical engineer has been with BMW since 1992 and has sat on its board since 2008, and has until now been responsible for production for the entire BMW Group. The chairmanship of the board of management currently belongs to Dr. Norbert Reithofer, whom the management is endorsing to chair the supervisory board (which Americans might call the board of directors). That role in turn is currently held by Professor Joachim Milberg, who will step down from his position in order to make way for Reithofer to take his place. Milberg is earmarked to remain with the company to oversee its corporate social responsibility and charitable activities. BMW has also announced the appointment of Klaus Frohlich to serve as its head of development with immediate effect. In his new capacity, Frohlich replaces Dr. Herbert Diess, who in turn has left Munich to take over the Volkswagen passenger car division. Below you'll find statements from both BMW and VW on their new appointments.

Top Gear names BMW i8 Car of the Year, Corvette, Ferrari, Mercedes also win big

The lads at Top Gear have released their listing of the finest cars of the past year, handing the ultimate honor to BMW's revolutionary i8 plug-in-hybrid supercar. "The i8 is a milestone in the annals of automotive history and a glorious statement for an exciting and positive future. The i8 delivers - and then some," the British mag wrote. The i8, though, was far from the only hybridized car to take victories. James May and Richard Hammond both highlighted hybrids as their personal cars of the year, with May saluting the Ferrari LaFerrari and the Hamster, unsurprisingly, heaping praise on the Porsche 918 Spyder. Jeremy Clarkson, meanwhile, opted to shock many by selecting not only an American car as his best of 2014, but giving the honor to of all things, a Corvette. Clarkson wasn't the only person to honor the USA's iconic sports car, with the new, 650-horsepower Z06 variant being named TG's Muscle Car of the Year. Other big winners include Mercedes-Benz, which TG honored for S-Class Coupe (Luxury Car of the Year), the new AMG GT (Sports Car of the Year) and the not-for-US C-Class Estate (Family Car of the Year). The 458 Italia Speciale A snagged a second win for Ferrari. The best of the rest include the Citroen C4 Cactus, Renault Twingo, Volkswagen Golf R, Lamborghini Huracan and Audi TT. Take a look below for the celebratory press blast from BMW. The BMW i8 wins Top Gear Car of the Year The BMW i8 has been named as Top Gear magazine's global Car of the Year 2014. The plug-in hybrid performance vehicle beat off some stiff competition from a host of other premium and luxury manufacturers to win the overall award. The editorial team of Top Gear commended the BMW i8 for its breadth of abilities. Its 1.5-litre three-cylinder turbocharged petrol engine combined with an electric motor gives searing acceleration and driver enjoyment but all wrapped in a package that takes BMW's EfficientDynamics philosophy to the extreme courtesy of CO2 emissions less than 49g/km and a 135mpg combined cycle figure. Charlie Turner, Editor in Chief at Top Gear magazine, said: "The BMW is a milestone in the annals of automotive history and a glorious statement for an exciting and positive future. The i8 delivers – and then some. It's the kind of car we should celebrate, a beautiful vision of the future, delivered now.
