Are more diesel scandals about to erupt?

More automakers may soon be embroiled, like Volkswagen, in diesel emissions scandals. According to the Daily Kanban, either the International Council on Clean Transportation (ICCT) or the Deutsche Umwelthilfe (DUH) will soon announce from 10 to 15 more cases of automakers cheating national diesel emissions rules. The outlet says three of the incidents are attributed to Opel. Studies conducted by the DUH, the University of Applied Sciences in Bern, Switzerland, and the UK's Leeds University found that Opel's diesel Zafira, Corsa, and Vectra models emit more NOx than European regulations allow when tested in ways that go beyond the European testing protocol, such as when done on a four-wheel rolling road instead of a two-wheel rolling road. Opel said the accusations had no merit. Specifically on the Zafira, the DUH asked Opel about the emissions findings, and Opel said that no General Motors software contains any measures to enable cheating. Opel then tested a Zafira of its own "both on a two- and a four-wheel roller dynamometer," finding that "The emission behavior determined in each case does not differ from one another." That makes this a case of he-said-she-said for the moment. The Daily Kanban's sources say the cheating methods "range from the crude to the highly sophisticated," with those at the latter end complex enough to render Volkswagen's methods "pedestrian." As for any automakers who might be named, the matter of real-world emissions exceeding a legal limit doesn't mean a carmaker has designed systems that cheat, it might mean the company designed the car to pass a test.

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 continues hunt for new chairman

Volkswagen is going to need a new chairman. And the question is not only who that will be, but when he or she will be selected. The German automaker held its Annual General Meeting in Hannover yesterday, the first in a baker's dozen years without Ferdinand Piech presiding as chairman. The gavel was wielded instead by Berthold Huber, a labor representative on the board who was named as interim chair. Piech was ousted along with his wife Ursula (who also sat on the board) after a failed attempt to push out Martin Winterkorn as CEO. According to Winterkorn, in speaking with Reuters in an article published by Automotive News, the industrial giant is working hard at finding a new chairman in short order. "The executive committee and the supervisory board are working hard to swiftly resolve the remaining issues with regard to the composition of the supervisory bodies in the best possible manner," Winterkorn said. The publication's German counterpart, however, paints a different picture. Speaking with Stephan Weil, the president of Lower Saxony who sits on the board as a shareholder representative, Automobilwoche says Volkswagen is in no rush to name a new chairman. The truth is probably somewhere in the middle. What is clear, however, is that the new chairman will need broad support from the company's labor representatives as well as its shareholders – including the Porsche and Piech families and government representatives from Lower Saxony and Qatar. Porsche Automobil Holding SE holds 50.7 percent of the company's shares, the State of Lower Saxony another 20 percent, Qatar 17 percent and the remaining 12.3 percent by other shareholders. Some have speculated that Winterkorn could be promoted to the chairmanship of the Supervisory Board, but could end up having his term as chief executive (and chairman of the managing board) extended instead, with the chairmanship going to another candidate.
