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.

Recharge Wrap-up: Tesla details factory expansion; Ford and SunPower raise money for Sierra Club

Tesla has revealed the details of the upgrade of its Fremont, CA factory. One major change is the addition of a dedicated production space for the dual-motor P85D version of the Model S. Robots will be doing the battery installation on the Model S to save some time, and new export docks allow Tesla to get the cars out the door and on the way to their new owners more quickly. The new robots that move the cars around the factory have been named after X-Men characters, which makes our inner geeks smile. Check out the factory upgrade in the time-lapse video below and read more at Teslarati or at the Tesla Motors Blog. A program in Beijing for privileged registrations for EVs hasn't had much success. Of the 1,424 lottery winners, only about 30 percent went on to register an electric car despite a two-month extension of the deadline to do so. Buyers are likely discouraged by the lack of charging infrastructure, which the city hopes to ameliorate with the addition of 1,000 new charging stations by the end of the year, and by requiring new and renovated developments to set aside parking specifically for EV charging.

Laws like the ones certain states have in place that block or otherwise restrict Tesla's direct-to-consumer business model are not helpful for companies that want to introduce new products to the market. They prevent companies from passing on savings to customers for whom they would likely make the difference in a purchasing decision. One possible solution would be to allow exemptions to certain selling restrictions for a certain number of vehicles sold. "This could give automakers the degree of control needed to work out kinks with early customers, develop scalable processes for supporting PEVs, and ensure that effective dealer performance standards are in place before handing the reins over to wholly independent retailers," according to UC Davis ITS.

The main purpose of the program is to move toward eco-friendlier carmaking at each of its plants worldwide.
