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.

2016 VW GTI Clubsport is a new breed of forbidden fruit

And this, friends, is the closest we'll ever get to the Volkswagen GTI Clubsport. As we were sad to report, this middle child between the standard GTI and the high-performance Golf R will not be coming to our shores, no matter how much we beg and plead. For those that need a refresher, the Clubsport was inspired by a concept originally shown at Worhtersee earlier this year. Its positioning means it's up on power – there are 261 (probably underrated) horsepower in this compact – although mum's the word on any upgrades to the suspension. As we previously noted, the extra 51 hp over stock will get the mid-level hot hatch to 60 in just 5.9 seconds, if you opt for the dual-clutch automatic, or an even six seconds with the manual trans. Loathe as we are to admit it, aside from the extra horsepower, most of the stuff about the Clubsport appears to be aesthetic. The body kit is all new and significantly more aggressive than the what's found on the GTI, while new 18-inch wheels are standard, although 19s can be optioned. Also larger, the twin chrome exhaust tips. In the cabin, there are far more aggressive sport seats, which are quite simply too cool to be sold in the US (just kidding, it's probably some silly federal regulation). We just had to mosey on down to the Volkswagen stand and check out the new GTI Clubsport. You can view all of our shots of the new hatch up top. Related Video:

Volkswagen Group Chairman Ferdinand Piech resigns

Ferdinand Piech, Volkswagen Group's chairman of the supervisory board, has resigned from the company. His wife, Ursula, has also left her position on the board. A statement put out by VW in German said the move was due to the fact that "mutual trust is no longer present," and the board's deputy chairman, Berthold Huber, will be interim chairman. It's been just two weeks since Ferdinand Piech told Germany's Der Spiegel magazine that he didn't want Group CEO Martin Winterkorn to become the next chairman and that he was keeping the CEO at a distance. That public comment surprised just about everyone, and led to a meeting in Piech's office in Austria. The leadership committee supported Winterkorn, and that was backed up by official, pro-Winterkorn messages from VW labor leaders and the German state of Lower Saxony. After that meeting, Piech agreed to support Winterkorn in public, but it was widely suspected that the fight wasn't over. Now it might be. This is not a changing, but rather an explosion of the guard. Piech lived for VW, and he and his Porsche kin still have a 51-percent stake in the Volkswagen Group. Frankly, we have a feeling that this still isn't over. The official statement from VW in English is below. Statement of the Executive Committee of the Supervisory Board of Volkswagen AG Wolfsburg, 25 April 2015 -- The Executive Committee of the Supervisory Board of Volkswagen AG discussed again today in detail the situation of the Volkswagen Group. 1.: The members of the Executive Committee have unanimously determined that in view of the background of the last weeks the mutual trust necessary for successful cooperation no longer exists. 2.: For this reason Professor Dr. Ferdinand K. Piech has resigned with immediate effect from his position as Chairman of the Supervisory Board and from all his mandates as a Supervisory Board member within the Volkswagen Group. In addition, Ms. Ursula Piech has resigned with immediate effect from all her Supervisory Board mandates within the Volkswagen Group. 3.: The position of Chairman of the Supervisory Board will be temporarily assumed by the Deputy Chairman Berthold Huber. Mr. Berthold Huber will chair both the Supervisory Board meeting on May 4 as well as the Annual General Meeting on May 5, 2015. 4.: Under the chair of Mr. Berthold Huber the representatives of shareholders and employees will in close cooperation determine the candidate for the new Chairman of the Supervisory Board.
