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 has received several tentative bids for Ducati

Italy's Benetton family is vying with motorbike firms and buyout funds for control of Italian motorcycle brand Ducati, which is being sold by Germany's Volkswagen, sources involved in the process told Reuters. Volkswagen, whose Audi division controls Ducati, has received several tentative bids with the Benetton family's investment vehicle Edizione Holding valuing the Monster motorbike maker at $1.2 billion, one of the sources said. As well as Edizione Holding, U.S. buyout fund Bain Capital, which owns a stake in Ski-Doo snowmobiles maker BRB, and two Indian motorbike firms, Eicher Motors and Bajaj Auto, have also bid for Ducati, the sources said. Indian carmaker Eicher controls Royal Enfield, a motorcycle brand established in 1893 which ranks as one of the oldest. Strategic bidders also include U.S. automotive firm Polaris Industries, which earlier this year said it would wind down its struggling Victory Motorcycle brand. A shortlist of bidders for a second stage of the auction could be selected as soon as Saturday, two of the sources said. Volkswagen adviser Evercore has a long list of bidders including private equity funds such as Ducati's previous owner Investindustrial, CVC Capital Partners, Advent and PAI, all hoping to outbid industry players, the sources said. If it gets to the second round, Edizione Holding could seek to form a consortium with a financial investor, two of the sources said, in a bid to secure control of Ducati, whose racers have won the Superbike world championship 14 times, with Carl Fogarty and Troy Bayliss its most successful riders. Audi, Edizione Holding, Investindustrial, Advent and PAI declined to comment, while the other interested groups were not immediately available for comment. PRICING CHALLENGES For some buyout funds, Ducati's valuation of up to $1.4 billion – which sources said is based on a multiple of more than 10 times its core earnings of roughly 100 million euros – is a tall order as they lack the synergies that some motorbike makers could achieve. But Investindustrial founder Andrea Bonomi, who sold Ducati to Audi for about 860 million euros in 2012, is serious about a comeback, one of the sources said. China's Loncin Motor was among a group of industry players that initially showed interest in Ducati, alongside Harley-Davidson. The latter has, however, decided against making a bid due to Ducati's price tag, while it could not be established if Loncin Motor had carried on bidding.

Jalopnik and Consumer Reports see who can pull off the best snow drift

The weather throughout much of the United States is pretty awful at the moment with some combination of extremely low temperatures, inches of snow and maybe some ice underneath it all. The folks at Jalopnik and Consumer Reports are making the absolute best out of a difficult situation by heading to CR's snow-covered test track and attempting to make the longest drift in a quartet of very different performance vehicles. Jalopnik brought along a Mercedes-Benz E63 AMG S Wagon, a Subaru WRX STI, a BMW 228i and a 1973 Volkswagen Baja Bug (heck yeah!) for the challenge. Also, the track was perfect for this group, with a mix of packed snow in places and still a few inches of unsullied powder in spots too. Ostensibly the goal was to get the tail to step out through a particular corner, but in reality this was more about having hilarious fun in the snow with fast cars. The result just looks like the best time humanly possible in this weather.
