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.

Volkswagen reveals Beetle GSR, R-Line convertible and two special GTIs

Volkswagen has chosen to really expand its performance-tuned portfolio at this year's Chicago Auto Show, bringing along a couple of new Beetles destined for model year 2014, as well as a pair of freshened GTI packages that you'll be able to buy almost right away.
The first, and splashiest of the Chicago goodies on the VW stand has got to be the 2014 Volkswagen Beetle GSR. Don't lose your temper, Acura Integra geeks; in this case, GSR stands for "Gelb Schwarzer Renner" or "Yellow Black Racer," and harkens back to a sport-tuned classic Beetle from the 1970s. For the 2014 iteration, the GSR gets a 210-horsepower version of VW's 2.0-liter turbo four-cylinder. That engine is enough to push the Beetle to 60 miles per hour in 6.6 seconds, and up to a top speed of 130 mph.
Of course, you'll have long-since noticed the shockingly yellow-and-black livery before you stumble across the Turbo badge on the rear deck. The GSR gets 19-inch alloy wheels, 235-section tires and a tea-tray rear spoiler, but it's the paint and graphics package that will decide if this is your (lemony) cup of tea. Things don't get any subtler inside the car, either, as VW has carried the colorway through to the interior, as well. Only 3,500 Beetle GSRs will be produced, with just more than half of those going to the US - call your dealer today, Wiz Khalifa.
