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.

11M VW diesels affected, Porsche and Audi under investigation

Volkswagen's diesel scandal is growing exponentially larger. In a new statement, the company admits that 11 million vehicles worldwide might be equipped with software capable of evading emissions testing. In addition, the Environmental Protection Agency is beginning an investigation into the 3.0-liter V6 in Audi models and the Porsche Cayenne in the US, according to The Detroit News. The automaker claims that from its investigation so far, the "relevant engine management software is also installed in other Volkswagen Group vehicles with diesel engines." However, the company finds that the "noticeable deviation" in test results and real-world numbers only relates to the Type EA 189 powerplant. That still leaves 11 million vehicles potentially skirting emissions rules, though. Governments around the world have started taking a closer look into the company, too. In the US, the EPA has begun testing VW's V6 diesel because "they were certified well before we knew what we know now," Christopher Grundler, director of the EPA's Office of Transportation and Air Quality, said to The Detroit News. The agency has started checking diesels from other automakers to make sure they're meeting the rules, as well. Germany, the European Union, and South Korea have instituted similar investigations. In response, VW is setting aside 6.5 billion euros ($7.25 billion at current rates) to cover servicing all of these diesels. The company admits that the figure might have to be adjusted depending on what happens next. The money is being deducted from its third-quarter earnings.

New vehicles from the Volkswagen Group with EU 6 diesel engines currently available in the European Union comply with legal requirements and environmental standards. The software in question does not affect handling, consumption or emissions. This gives clarity to customers and dealers. Further internal investigations conducted to date have established that the relevant engine management software is also installed in other Volkswagen Group vehicles with diesel engines. For the majority of these engines the software does not have any effect. Discrepancies relate to vehicles with Type EA 189 engines, involving some eleven million vehicles worldwide.

GM outsold VW globaly in first quarter, Toyota reports numbers next week

General Motors released its first quarter sales figures this week, reporting that it sold 2.36 million cars and trucks worldwide. That figure represents an increase of 3.6 percent when compared to the same period last year. GM's growth was attributed to many factors, including global Cadillac sales that were up 26 percent and Chevrolet posting a one percent increase over last year (this marked Chevy's tenth straight year of record global sales).
Volkswagen came in just behind GM, as the German automaker reported global sales from January through March at 2.27 million vehicles, an increase of five percent when compared to last year. While that number was strong, VW is cautioning that markets outside China and the US, such as those in Europe, are becoming a challenge as economies falter.
Yet to report sales is Toyota, current holder of the global world sales crown (the Japanese company sold 9.75 million cars last year, against 9.29 million sold by GM and 9.1 million vehicles sold by VW). Even though GM and Toyota both say they don't care who sells the most units, it is unquestionably a strong bragging point and sales equate to revenue. That said, Toyota will report its first quarter numbers next week.
