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.

Leaked Audi product roadmap may confirm R8 with V6 engine

About a year ago, we reported that Audi was considering downsized engines for the new R8, which launched in V10 form. This is partially due to the Chinese market's desire for smaller displacement engines, and partially due to R8 technical lead Roland Schala's statement that a "V6 is a perfect engine for this car." This leaked upcoming product schedule, passed on by our friends at Autobahn.eu, seems to confirm these rumors. Based on the information in the image above, the R8 V6 is due in 2018. The rest of the product map seems to square with vehicles we know are in the pipeline. We spied the SQ7, A5, and R8 Spyder about a year ago, and the TT RS a few months ago. We told you in December a new Q5 is on the way, too. We just heard a credible rumor that the RS3 is on the way in 2017 as a 2018 model, and may even come to America, which squares with what we're seeing here. And we drove the Q7 E-Tron in 2015 – it's going on sale in Europe soon. This graphic puts the on-sale date as October 2017; that could be for the US market. Puzzlingly, this graphic doesn't discuss the Q2, which Audi just teased today. We're not sure what to make of that. Now onto the fun stuff. 2018 should be when Audi reveals a new A8 (featuring, most likely, a version of the futuristic Virtual Dashboard seen at CES) and A7, an RS 5 Coupe launching a few months after the A5/S5, a new A6, and the already-confirmed Q8 SUV. All expected or already confirmed. What about the cryptically-named "C-BEV?" If we extrapolate that to mean C-segment EV, if could be the Audi version of the stand-alone EV that VW is reportedly developing, and no, it's not the next E-Golf. We expected this MEB-based vehicle to debut in 2018, before the next-generation Golf, so again our rumors square nicely with what this roadmap tells us. Let's leave it at this: if you're an Audi fan, the next few years are going to be quite exciting. Expect some of these rumors to be confirmed in Geneva, so keep your eyes here for more Audi and VW info. Related Video:

VW redoes A-ha's 'Take On Me' music video

Volkswagen has been responsible for its fair share of witty, clever commercials. "Tiny Vader" might be the most popular, but somehow, we think this newest spot will find a big audience. VW delivers not so much a cover, but a reimagining, of 1980s Norwegian pop band A-ha's famous music video for "Take On Me."
The original opens with an animated motorcycle race, which is revealed to be part of a comic book. VW's version replaces the motorcycle with a Passat, which strikes us as an oddly sober choice when there are cars like the GTI and Beetle in VW's portfolio. But never mind that - take a look down below for the entire 46-second spot. For reference, we've also included the original music video. And if you aren't a fan of the musical stylings of A-ha, just think, VW's choice of 1980s music could have been much worse.
