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.

The VW Sport Coupe GTE Concept promises exciting things for brand's future [w/video]

In recent years, it seems as though the Audi allotment of design talent from the Volkswagen Group has gotten braver, while the VW designers have become more conservative. One look at the current Volkswagen range reveals a lot of tidy sheet metal, but hardly any that rank as evocative or emotionally compelling. If the rhetoric around this Sport Coupe GTE Concept turns to action, however, VW's mass-marketed cars could become a lot more interesting to look at. Sharp creases and bold graphics can be found on just about every inch of the concept, and the large wheels at either extreme corner help to sell this as a "four-door coupe" more than most executions of that now hackneyed styling term. And, if you like what you see, then you might want to hold out for quickly approaching versions of this look on production models. Design head Walter de Silva says this language will be "shaping the immediate future" for VW product. Mechanically, the Coupe also previews more hybridization for the VW line. The concept has a plug-in hybrid powertrain, with a turbo 3.0-liter V6 driving the front wheels, and an electric motor sending yet more power to the rear. You can read up on the details in our official post from a few days ago, or just click through the pretty pictures in the gallery above. SPORT COUPE CONCEPT GTE MAKES WORLD DEBUT AT THE GENEVA AUTO SHOW Four-door coupe marks beginning of a new design era at Volkswagen Wolfsburg/Geneva, March 2015 -Volkswagen will debut the Sport Coupe Concept GTE at the 2015 Geneva International Motor Show, heralding a new and progressive Volkswagen design language. "Evolution and revolution come together in the Sport Coupe Concept GTE. This concept is based on Volkswagen design DNA, which has been visibly sharpened even more. It shows how the highest-volume brand of our Group is shaping the immediate future," says Walter de Silva, Head of Design of Volkswagen AG. Dr Heinz-Jakob Neusser, Volkswagen Brand Board Member for Development, elaborates: "This breathtakingly dynamic coupe is unlike any other to appear in this class. The design of the Sport Coupe Concept GTE is an impressive alternative to the classic sedans of the B and C segments-it has the style of a sport coupe that is enriched by the functionality of a large hatchback and the interior space of a sedan." Klaus Bischoff, Head of Design of the Volkswagen Brand, adds: "The Sport Coupe Concept GTE is another milestone of expressive design.

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.
