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 scores dominant 1-2-3 finish at Monte Carlo Rally

Racing calendars change from year to year, but most series have that one race they just couldn't do without: the Monaco Grand Prix for F1, Le Mans for endurance racing, Dakar for rally raid, the Indianapolis 500 for Indy, the Daytona 500 for NASCAR... and for the World Rally Championship, it's the Monte Carlo Rally. Winning the Monte brings with it its own measure of bragging rights, but locking out the podium is another story altogether. And that's just what Volkswagen did this weekend on the Cote d'Azur. The hard-fought season-opener saw nine-time world champion (and seven-time Monte Carlo Rally winner) Sebastien Loeb return with Citroen, but ultimately it was the VW team that won – and won big, taking a commanding 1-2-3 finish. Sebastien Ogier (with Julien Ingrassia) finished first, followed by Jari-Matti Latvala (with Miika Anttila) in second and Andreas Mikkelsen (with Ola Floene) in third, all of them in the Volkswagen Polo R WRC that was just updated in time for the start of the season. The rally passed right through the Forest Saint Julien where Ogier was born, and at the end of it all, Mikkelsen walked little more than 50 steps from the Volkswagen garage to his condo at Quai Antoine 1er in Monte Carlo. It was only the second time VW has locked out the podium since hitting the scene two years ago, following the German team's 1-2-3 finish in Australia last season en route to its second consecutive world championship. This also marked the second year in a row that Ogier and VW have won the Monte, after narrowly losing out to Loeb in '03. The achievement in Monaco this weekend made VW only the fifth manufacturer to take the top three spots in the Monegasque capital: Renault-Alpine became the first in 1973, followed by Lancia (with the Stratos) in '76 and then again (with the Delta Integrale) in '89, Audi sandwiched between in '84 and Citroen with the "dream team" of Loeb, Colin McRae and Carlos Sainz in 2003. (Peugeot achieved the same in 2009, but that was when the Monte Carlo Rally had left the WRC and was run as part of the less prominent and lower-spec Intercontinental Rally Challenge.) Not even Subaru, Mitsubishi, Toyota or Ford - all dominant forces in their time - can claim that feat. The victory secures the Polo R WRC's place as the most dominant car in the championship, winning over 85 percent of the rallies in which it has been entered since its debut in 2003.

VW could look outside its own ranks for next CEO

Companies have two options when coming up with succession plans – hire within, or go outside its ranks. Either choice comes with advantages and disadvantages, to be sure. Hiring within means generally getting someone familiar with the company and its culture and traditions, while going outside is ideal if you're looking to shake things up and bring in fresh ideas. It's unclear which avenue the Volkswagen Group will go down when it comes time to replace its head man, Herr Professor Doctor Doctor Herr Martin Winterkorn, but he isn't ruling out a trip outside of Wolfsburg. Winterkorn has already given the reins of the VW brand to former BMW board member Herbert Diess, while Andreas Renschler, a former Daimler board member, is heading up VW's truck group. Now, Winterkorn has made some statements to a German weekly that indicate the most important thing about his successor isn't necessarily his (or her, though no women appear to be on the short-list) previous employer, Motoring.com.au is reporting, so much as his qualities as a leader and an engineering background. "A Volkswagen boss has to have a big affinity to our products. He needs to be close to customers and he needs to have a relationship with dealers," Winterkorn told Stern. "Like always, it depends on the personality and it also helps if the candidate is an engineer." Motoring throws out a couple of potential candidates from within, including Porsche boss Mathias Muller, Audi Chairman Rupert Stadler and engineering guru Ulrich Hackenberg, in addition to both Diess and Renschler. And while each candidate has a lot of potential, the only thing that's guaranteed right now is what Winterkorn has already said: "The decision about who will succeed me is not an easy one for the supervisory board."
