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.

Carmakers ask Trump to revisit fuel efficiency rules

Car companies operating in the US are required to meet stringent fuel efficiency standards (a fleet average of 54.5MPG) through 2025, but they're hoping to loosen things now that President Trump is in town. Leaders from Fiat Chrysler, Ford, GM, Honda, Hyundai, Nissan, Toyota and VW have sent a letter to Trump asking him to rethink the Obama administration's choice to lock in efficiency guidelines for the next several years. The car makers want to revisit the midterm review for the 2025 commitment in hopes of loosening the demands. They claim that the tougher requirements raise costs, don't match public buying habits and will supposedly put "as many a million" jobs up in the air. The Trump administration hasn't specifically responded to the letter, although Environmental Protection Agency nominee Scott Pruitt had said he would return to the Obama-era decision. The automakers' argument doesn't entirely hold up. While the EPA did estimate that the US would fall short of efficiency goals due to a shift toward SUVs and trucks, the job claims are questionable. Why would making more fuel efficient vehicles necessarily cost jobs instead of pushing companies to do better? As it is, even a successful attempt to loosen guidelines may only have a limited effect. All of the brands mentioned here are pushing for greater mainstream adoption of electric vehicles within the next few years -- they may meet the Obama administration's expectations just by shifting more drivers away from gas power.

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.
