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 bringing production GTI Clubsport to Frankfurt

"No plans for the car to be sold here." It's probably good I read that part of the email from Volkswagen before I looked at the photos and read the release for the car you see above. It's the production-spec GTI Clubsport. It's coming to the Frankfurt Motor Show. It's awesome. And I want one. I know, I'm kind of a GTI fanboy, but really, there's a lot to like here. The special-edition hot hatch is essentially a road-going version of the concept Volkswagen brought to Worthersee this year, complete with a more powerful engine. It produces 261 horsepower – a healthy increase over the 210 hp of the base GTI (or 220 if the car is fitted with the performance pack) – and can even crank out 286 hp for short bursts, thanks to an overboost function. Hitting 62 miles per hour takes six seconds flat with the six-speed manual gearbox, and that time is reduced to 5.9 seconds should you opt for the six-speed dual-clutch automatic. Even with these upgrades, VW says the GTI Clubsport will still return nearly 34 miles per gallon with the manual transmission. Volkswagen doesn't specifically mention any chassis upgrades, however. In its press release, VW simply says that the GTI Clubsport "has groundbreaking handling properties at high speeds and breathtaking cornering speeds." Cool. I'm sure it'll be a riot. A lot of the exterior is new: the front bumper, side sills, rear diffuser, roof spoiler, and aluminum wheels are all unique to the Clubsport. Buyers can choose between 18- or 19-inch rollers, the tailpipes are larger than those on a standard GTI, and the LED lights out back have a black/red, dark finish. Inside, the Clubsport comes with racing buckets covered in tartan fabric (of course) and there's Alcantara everywhere. Fellow GTI fans, get excited about this one – even if it's just another delicious piece of forbidden fruit. Still, I can't wait to see it live in Frankfurt next week.
