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.

VW agrees to halt next-gen rally car development to help others stay in WRC

Volkswagen has petitioned the FIA to hold on to the current specifications for cars in the World Rally Championship, according to Autosport.com. The move is evidently an effort to keep as many competitors in the sport as possible, despite the fact that using the current spec racers may actually hurt Volkswagen's chances at winning. The three factory teams currently competing in the WRC are at the end of a three-year homologation cycle at the end of 2013, and new cars are expected to bow next year. But developing new racers could cost as much as $4.7 million.
That price tag would put M-Sport (which fields Ford racers) out of the WRC game for 2014 and would put Citroën participation in question as well. VW has already begun work on the next iteration of its Polo R WRC, and the hatch has nabbed four wins in six rounds this season. Now it appears that car won't bow until at least 2015. The FIA has officially agreed to freeze homologation of new WRC cars until the end of next season.

Autoblog Minute: VW Q3 financial woes, 2015 Tokyo Motor Show

Consumer Reports pulls its Tesla recommendation, the U.S. Copyright Office offers a ruling affecting car owners, VW gets hit hard with third-quarter losses, and lots of exciting news from Tokyo. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Consumer Reports pulls its Tesla recommendation, the U.S. copyright office offers a ruling that affects car owners and gear heads, VW gets hit hard with third-quarter losses, and lots of exciting news from Tokyo. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. After a week away testing vehicles for Autoblog's Tech of the Year award, we're back in the office to recap the week in automotive news. [00:00:30] One of the things you might have missed was Consumer Reports pulling its recommendation of Tesla's Model S sedan. The blemish for Tesla comes after a tally of reviews from customer surveys. The most common problem areas for the Model S as cited by survey takers included: the drivetrain, power equipment, charging equipment, body and sunroof squeaks, rattles, and leaks. So lots of stuff. Though they could not ignore a score of "worse-than-average", Consumer Reports still [00:01:00] highlighted the fact that the Model S was "the best performing car" they've ever tested. Telsa CEO Elon Musk took to social media to defend his sedans saying: "Consumer Reports reliability survey includes a lot of early production cars. Already addressed in new cars." And, "Tesla gets top rating of any company in service. Most important, CR says 97% of owners expect their next car to be a Tesla (the acid test)." In Financial news, Volkswagen took a hit and reported an operating loss of [00:01:30] $3.84 billion. This is the first such loss for VW in 15 years. Toyota reclaimed the crown as the world's largest automaker as well. It's important that it's not all doom and gloom for VW though in Q3. Sales revenues were up and the company's automotive division boasts $30 billion dollars in liquid assets. It's a sizable war chest that will no doubt come in handy, as the company has yet to feel the full brunt of the diesel emissions scandal. Good news for gear heads. The US copyright office [00:02:00] ruled in favor of mechanics and car owners by granting an exception to existing copyright law. The law was originally meant to prevent software pirating and bootlegging of Hollywood movies.
