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.

VW readying two-row CUV concept for Detroit

We're likely getting yet another glimpse of Volkswagen's future crossover at the upcoming 2015 North American International Auto Show in Detroit, in January. According to Automotive News, two anonymous sources within the automaker indicate a CUV concept will be shown there. The concept is said to be a five-passenger preview of the brand's future seven-seat model. Previous versions of the crossover have carried the name CrossBlue (pictured above), but there was no indication whether or not that would continue. The original three-row concept debuted at the 2013 auto show in Detroit, and VW followed it up with the CrossBlue Coupe Concept in Shanghai later that year. In early 2014, the company announced the CUV would go into production sometime in 2016, along with plans to invest $7 billion in North America over the next five years. During the summer, the automaker made things even more official when it declared plans to invest $900 million to build a 538,000-square-foot expansion into its Chattanooga, TN, factory to assemble the new model. Production of the crossover was slated to begin by the end of 2016, at the time. According to Automotive News, even more changes in VW's CUV lineup are on the way. The Tiguan is reportedly getting an update next year that could be joined by coupe and long-wheelbase variants, as well.

VW outsells GM in China for first time in 8 years

In case you didn't know, Volkswagen is hell-bent on becoming the largest automaker in the world. The German carmaker has inched closer to that goal, having outsold General Motors in China last quarter for the first time in eight years.
Volkswagen's sales in China, its largest marker, increased by 21 percent last quarter to 704,991 units. Those numbers almost tripled GM's third-quarter growth, and were enough to beat out the American automaker's 664,765 sales. GM, however, still leads in year-to-date sales in China by a slim margin of around 77,000 units. The Asian nation also happens to be GM's largest market, and according to the report in Automotive News, China's car market may grow to be larger than the US, Japan and Germany combined in three years' time.
About the news his company was bested in China by VW last quarter, GM CEO Dan Akerson is quoted saying, "It's not whether you're the biggest car manufacturer. It's whether you want to be the most profitable." It should be noted of these figures that GM includes truck figures, yet excludes Hong Kong and Macau from its Chinese sales numbers, while VW does just the opposite. Through September of this year, Volkswagen had 5 of the 10 best selling vehicles in China. GM boasted three of the cars on that list.
