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 Group names Paefgen head of classics program

You may remember the name Franz-Josef Paefgen. Until recently, the German engineer and executive was head of both Bentley and Bugatti. Before that he was chief executive of Audi, after working for several years at Ford. He technically "retired" earlier this year, but like the cars he helped create, an executive like Paefgen could never really retire. So it should come as little surprise that the Volkswagen Group has named Dr. Paefgen head of its Classic program.
In his new capacity, Paefgen will oversee the historic automobile activities of the entire VW Group, including those of Volkswagen, Seat, Skoda, Audi, Lamborghini, and of course Bentley and Bugatti. It strikes us as a suitable semi-retirement for the man responsible in no small part for the Bugatti Veyron and Bentley Mulsanne, to name just two, and who was decorated in 2006 by the ACO as the "Spirit of Le Mans" for his contribution to endurance racing.

Matthias Muller officially named VW Group CEO

While the vast number of rumors made it seem like a foregone conclusion, Porsche boss Matthias Muller has officially been named Volkswagen Group CEO to replace the recently resigned Martin Winterkorn. His contract runs through the end of February 2020, and until a replacement is found, Muller also gets to hang onto his old job as chairman of Porsche. At the same time, the VW Group Supervisory Board is announcing a massive structural reorganization across the entire company, with the new management model in place by the beginning of 2016. Contrary to previous rumors, Michael Horn remains as President and CEO of VW Group of America. The board wants a greater emphasis on brands and regions going forward, and the scale of this shift can be seen in the US. On November 1, VW Group business in the US, Mexico, and Canada is being combined under the leadership of current Skoda chairman Winfried Vahland. However contrary to previous rumors, Michael Horn remains as President and CEO of VW Group of America. Other brands are also seeing some significant changes mechanically. Porsche, Bentley, and Bugatti now fall under the Group's "sportscar and mid-engine toolkit." This means that the brands will start sharing standardized technical parts. A Chief Technical Officer across all of the company's brands will also start working toward future innovations. The new brand-centric view means the end of a group-wide production department. "Going forward, the brands and regions will also have greater independence with regard to production. So it follows that they should also hold the responsibility for these activities," Berthold Huber, interim Chairman of the Supervisory Board, said in the announcement. In a statement with the press release about his promotion, Muller promised to turn the company around after such an international crisis. He said: "My most urgent task is to win back trust for the Volkswagen Group – by leaving no stone unturned and with maximum transparency, as well as drawing the right conclusions from the current situation. Under my leadership, Volkswagen will do everything it can to develop and implement the most stringent compliance and governance standards in our industry." Matthias Muller appointed CEO of the Volkswagen Group Muller remains Chairman of Porsche AG until a successor has been found Matthias Muller (62) has been appointed CEO of Volkswagen AG with immediate effect.
