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.

Next Volkswagen Golf R to get 286 horsepower?

The seventh-generation Volkswagen Golf hasn't launched in the United States just yet, but we're already setting our sights on the range-topping R model. According to Autocar, the next Golf R will be more powerful than the current version, producing 268 horsepower and 280 pound-feet of torque, making it the most powerful production Golf ever.
Powering the new Golf R will be a further evolution of Volkswagen's well-liked 2.0-liter turbocharged inline-four, and when mated to a six-speed dual-clutch transmission, the hotter hatch will reportedly be able to sprint to 62 miles per hour in five seconds flat. That's over half a second quicker than the current US-spec model.
Other updates for the new Golf R include the addition of VW's Haldex 5 all-wheel-drive system found in the latest iteration of 4Motion. Furthermore, thanks to the use of lightweight materials, the new R is expected to weigh in around 2,650 pounds - that's a massive 675 pounds less than the current US-spec car. The exhaust has reportedly been reworked to provide more aural delight, as well.

VW readying CC Shooting Brake?

This was bound to happen. Volkswagen's relentless drive for big volume has the brand mining seemingly every niche it can find for additional sales worldwide. And with its CLS Shooting Brake, fellow countryman Mercedes-Benz has already shown that a wagon based off of a "four-door coupe" can look dead sexy and command extra dollars. So it follows that the Volkswagen CC (whose existence is all but directly attributable to the success of the original CLS sedan) will also get a load-lugging variant. That's according to the UK's Autocar, which notes that the five-door will come in the CC's next generation.
According to the report, the next CC will be available in front and all-wheel drive variants with the usual assortment of gas and diesel four-cylinders found in the Wolfsburg empire, with the possibility of a gas plug-in hybrid model, too. The rakish estate will ride atop VW's MQB architecture, a shorter variant of which is also found underneath the new Golf. The scalable chassis is set to spread like kudzu throughout the company's lineup, but the CC probably won't happen until after the launch of the next European-market Passat in 2015.
Will we get it in North America? Hard to say. Volkswagen sells the standard CC saloon here, but not in particularly large numbers, and when the company moved to a North American-specific Passat, it dumped the wagon variant. The traditional VW estate apparently continues to pick up sales momentum abroad, however, making the CC Shooting Brake a seemingly natural fit for buyers who still want the utility of a two-box form but can afford to sacrifice a bit of cargo room in the name of style.
