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 says goodbye to Eos, Routan in 2015 updates

Usually automakers announce changes to their lineup individually on a vehicle-by-vehicle basis, but sometimes it all comes at once – especially when the changes are ones we either expected or might not otherwise notice. That's the path Volkswagen has gone with changes to its US lineup for 2015. The biggest change is what we already knew: that the new Golf arrives for the 2015 model year, bringing with it the new GTI, Golf R, e-Golf and Golf SportWagen (to replace the previous Jetta wagon). But there are some new details as well. For starters, Volkswagen has finally confirmed that both the Eos and the Routan – both long rumored to be on their way out – will be exiting this year. The Eos hardtop convertible, pictured above, will linger for one last year, its Sport trim replaced by a new Final Edition with 18-inch wheels, two-tone leather interior and enhanced equipment. Meanwhile the Routan, which hasn't actually been built in over a year, is finally dead, as VW confirms it has dropped the Chrysler-built minivan from its lineup for 2015 altogether. The German automaker has also confirmed that the Touareg is getting a facelift early in the new year, which we expect will closely follow the revisions revealed a few months ago ahead of the Beijing Motor Show. Finally VW has announced an upgrade to its 2.0-liter TDI. Fitted to the Golf, Jetta, Passat and Beetle, the updated diesel gets 10 more horsepower with output now up to 150 hp and 236 pound-feet of torque. Scope out the full list of announcements in the press release below. MODEL YEAR 2015: NEW GOLF FAMILY, REDESIGNED JETTA, AND NEW TDI® CLEAN DIESEL ENGINE HEAD THE CHANGES Jul 22, 2014 In a busy year, Volkswagen will also add a new Golf SportWagen, an all-new Golf R, a redesigned Touareg SUV, and the company's first U.S.-market EV, the e-Golf - All-new Golf is bigger, lighter, and more fuel-efficient than the previous model, seats five, and has a larger trunk than any midsize sedan - New Golf GTI has 210-horsepower engine, with improved fuel efficiency and performance - e-Golf is Volkswagen's first full Battery Electric Vehicle for sale in the U.S.

Volkswagen Cross Coupe GTE is a sleek take on brand's future CUV

Volkswagen continues its long tease leading up to an eventual US-built, seven-passenger, three-row crossover with the Cross Coupe GTE at the 2015 Detroit Auto Show. While it's still affixed with the tinsel of a concept car, there are a lot of details that will arrive on VW's eventual production crossover. The wheelbase of the GTE is said to be identical to the production model, although this five-passenger CUV is actually about a foot shorter overall, Volkswagen's chief of design, Klaus Bischoff, told Autoblog. The overall shape of the GTE's greenhouse, meanwhile, will also be very similar to the car that'll come to market, although more progressive from the C-pillar forward (that's right kids, that sexy sloping rear end isn't for production). Despite the aggressive rake, a peek in the GTE's trunk revealed room for the CUV's third row. Beyond hinting at a new addition to the company's lineup, the GTE also gives us a look at future Volkswagen design, including the use of four-element LED running lamps. Body lines will be as sharp as is feasible. Look for the production version of Volkswagen's seven-passenger SUV at the end of next year. Until then, check out the two-row concept, courtesy of our live images from the 2015 Detroit Auto Show.
