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.

Volkswagen Golf R 400 Concept still makes us swoon

We know, we know – this hot little guy isn't really new or anything. Volkswagen first rolled out the Golf R 400 concept in Beijing earlier this year, and since its debut, we've heard rumors that the German automaker might-perhaps-maybe-hopefully build the thing. Its showing here in Los Angeles simply marks the first time it's debuting in America, and honestly, we can't get enough. So here it is, again. Hello, Golf R 400 – we love you. And what's not to love? What starts as a normal Golf R gets better with a more aggressive appearance, big wheels, some tasteful neon yellow accents, and a whole mess of power. The original concept packed 395 horsepower from an overblown 2.0-liter turbo-four, though the most recent reports suggest a production version could produce over 400 hp. To keep it all in line, the concept has all-wheel drive. And inside, it's the same functional, comfortable Golf we've always loved. There's nothing left to say, really. We love this car, and you should, too. Check it out in the gallery above.

Winterkorn receives support of VW board, leadership battle continues

Strange things have been happening - in public, that is - at Volkswagen over the past few weeks, kicked off when VW Group chairman Ferdinand Piech reportedly said he didn't want Group CEO Martin Winterkorn to be the next company chairman, and that he was keeping Winterkorn "at a distance." Winterkorn's ascension was widely believed to be a fait accompli. We were really just waiting for office furniture and desk plaques to be moved around. That led to a meeting of the six-member supervisory board's leadership committee in Piech's office in Salzburg, Austria, not at Group HQ in Wolfsburg, Germany, where the five other members of the committee came out in support of Winterkorn. They also suggested they might extend his contract when it ends in 2016, and then gave Piech an ultimatum to agree to public support of the CEO or they would demand Piech's resignation. At the same time, the company's labor reps and the German state of Lower Saxony issued statements supporting Winterkorn. It's said that the chairman has a number of gripes with the CEO, prime among them being the state of the company's US business for the core Volkswagen brand. Market share has dropped to two percent in the United States and Winterkorn admitted that his team hasn't been properly engaged with our market. Years of effort put into a budget car haven't resulted in much except the company saying it finally knew how to do one, and that was a year ago. It's losing share in Brazil, overall profit margins are down, BMW is taking possession of the green-car credentials among German brands, and it's said that Piech doesn't believe Winterkorn has the vision to do what's necessary. Having agreed to play along and now in "diplomacy phase," some say a little light has gone out of Piech's star inside the company, while others wonder if this battle is truly over.
