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.

Car and Driver shows off awesome 1960s ads

Someone must have recently rediscovered the keys to the archives at Car and Driver, and the access has been put to good use. Following last month's fantastic look at automotive ads from the '50s, there's now a new gallery running from March 1960 through December 1969. This collection provides a great overview of a decade full of iconic cars. If you're a fan of Carroll Shelby, particularly his Mustangs, then there's a lot to love among this group. One ad from July 1965 aimed to sell the GT350, but with an ocean of text and a tiny picture, it probably could've used a once-over by Don Draper's team. By December '65, the copywriters ironed out the problems with a spot proclaiming boldly "Shelby GT350 is 'Son of Cobra.'" The company offered some great accessories, too. For those into European motoring, there's a humorous attempt to sell the Alfa Romeo Giulia as both a racecar and family hauler. Toyota also boasts about the winning record for the 2000GT. Among the best text comes from BMW for lines like: "What's BMW got? The most advanced high-performance engine in any production car, for a cruising speed of 100 mph." Of course, Volkswagen's famous "Lemon" ad for the Beetle also gets its due here. Separately, each of these ads is fascinating, but taken together they tell the story of a great decade of motoring. Go give them all a read at Car and Driver.

VW will delay projects to cope with diesel scandal

Volkswagen's diesel emissions scandal will require the sacrifice of far more than just executives and money. It's also going to result in the cancellation of various projects, a process that new CEO Matthias Mueller said "won't be painless." "We will review all planned investments, and what isn't absolutely vital will be canceled or delayed," Mueller said while addressing the embattled company's employees. The former Porsche boss also said the money set aside by the German giant – about $7.29 billion – won't be enough to cover recall expenses, fines from governments in affected countries, and the expected deluge of lawsuits from disgruntled TDI owners. According to Bloomberg, that figure probably won't even be enough to match the fines Uncle Sam is likely charge, pegged to be around $7.4 billion, according to one analyst. It's expected that VW could delay a further push for share in the North American market, which would include a $1-billion investment in its Puebla, Mexico, factory. But it will take more than cancellations and delays, analysts claim. "It's going to be tough to find projects they could chop that will actually move the needle," JPMorgan Chase's Jose Asumendi told Bloomberg. "What they really need to do is get costs under control." That, according to Bloomberg, is already setting up a showdown between management and labor. The latter wants a reduction in VW's $17.4-billion research-and-development budget – the world's largest and more than what Ford and General Motors spend combined – while the former wants to slash personnel costs. Bloomberg also spoke to analysts who claimed the company should look into reductions in purchasing costs as well as trimming sponsorships. It's impossible to know just how extreme Volkswagen will need to get with cancellations, delays, and cost-cutting, but it's becoming increasingly clear that the effects of this scandal will likely be felt far longer than the controversies that surrounded other automakers like General Motors and Toyota.
