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.

European car sales up 8% in February

Three weeks ago an analyst increased projections for European car sales this year, expecting them to climb three percent compared to last year instead of 2.7 percent. That number is a postive sign after years of hard times but it turns out February was especially good, overall European sales climbing eight percent on a wave of southern European recovery and discounts - and this comes after five months of gains including January's 7.2-percent jump over the year before.
The only country of Europe's five largest markets to post a decline was France, just as it did in January, Germany, the UK and Italy posting solid double-digit numbers, Spain rocking the charts with an 18-percent increase because of a government program to encourage trade-ins.
The only brand to miss the wave was Volkswagen, dropping 0.8 percent as it watched the double-digit growth at sister brands Audi, Seat and Skoda lift the Volkswagen Group sales up by seven-percent. Peugeot overcame flat sales at Citroën to improve the group by 3.5 percent, BMW and the Mercedes-Benz/Smart combo rose by four percent, the Fiat group jumped 5.8 percent, Ford was up 11 percent, the Renault Group 11.5 percent, General Motors 12 percent and the Toyota clan by 14 percent.

Editors' Choice: Top Five 2013 Geneva Motor Show Debuts

We've returned from a very busy week in Switzerland, and in going back over all of our 75 stories from the Geneva Motor Show, our editors have gathered up their personal favorite debuts from the European expo.
The wonderful thing about the Geneva show is just how wide of an array of vehicles are on display - everything from funny little one-off EVs to the most exotic of supercars to, well, truly ridiculous displays of coachbuilding. And because of that, this list of our editors' favorites might not be as predictable as you think.
But we don't want to give anything away just yet. Scroll down to have a look at our team's favorites from Geneva.
