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.

Lamborghini has been developing an IPO strategy 'for a long time'

Porsche AG isn’t the only Volkswagen AG brand that has been quietly preparing for a potential initial public offering. Italian luxury-car maker Lamborghini has been developing a strategy how to present itself to stock-market investors since well before Volkswagen asked each of its brands to come up with virtual equity stories, according to the unitÂ’s Chief Executive Officer Stephan Winkelmann. “WeÂ’ve been working on this with other agencies in order to create clarity,” Winkelmann said. “As a brand, weÂ’ve done so for a long time, to show what worth, what value we have. Up until a little while ago, it wasnÂ’t so well known.” Porsche became EuropeÂ’s most valuable automaker last month, when its market capitalization overtook that of VW a week after its IPO in Frankfurt. The debut of the 911 maker was a bold move into public markets, which have been largely shut for most of the year. VW CEO Oliver Blume has said he sees the listing as a blueprint to unlock more value from the groupÂ’s brands that also include Audi and Bentley. “An IPO drill is exactly what you do to show the public how solid you are and what is in progress for the future,” Winkelmann said. “We have a clear story and strategy for that.” Audi, which oversees VWÂ’s premium brands, said last month there are no concrete plans for an IPO of Lamborghini. A previous push to potentially spin off the carmaker and motorcycle brand Ducati ran into opposition from labor leaders. Still, LamborghiniÂ’s recent profit gains -- including a 31.9% operating margin in the first half of this year -- make a solid case for a stock-market listing, said Michael Dean, an analyst at Bloomberg Intelligence. “An IPO is something that could potentially happen in the next 18 months, depending on market conditions,” Dean said. “A ˆ15 billion valuation is entirely justifiable and could be even higher, given the margin metrics.” LamborghiniÂ’s deliveries rose 8% to 7,430 vehicles in the first nine months of the year. Operating profit climbed 69% to ˆ570 million ($567 million). Related video: This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings.

Car and Driver 10Best list cracked by Tesla Model S, BMW 3 Series left off

Car and Driver is keeping new blood pumping into its annual 10Best cars list with three new entries making it on for 2015 and a perennial favorite falling off. Among the biggest shocks this year is that the BMW 3 Series and 4 Series are no longer named, despite years of some portion of that lineup earning a mention. In another surprise, the Tesla Model S (specifically in S 60 trim to fit under the $80,000 cost cap) makes it to the 2015 roster and is the only electrically motivated member of the group. Despite the loss of the 3 Series, BMW isn't entirely shut out this year, because the M235i gets its name on the list. Car and Driver argues that the little coupe feels like a welcome throwback to the E46 chassis M3 of the early 2000s. In addition to the Model S, the final newbie to the annual group is the 2015 Ford Mustang GT. The inclusion of these new members knocks the Audi A6/A7 family and Ford Fiesta ST out from the 2014 rundown. The other seven models carry over from last year, including the Cadillac CTS, Chevrolet Corvette Stingray, Honda Accord, Mazda3, Mazda6, Porsche Boxster/Cayman and Volkswagen Golf/GTI. The 2015 10Best cars list certainly seems to have something for everyone from the hot hatch fan to the family man and even the green car driver, thanks to the addition of the Tesla. Head over to Car and Driver to read its detailed explanations for each vehicle's inclusion, but if you've got a difference of opinion or just really like the list, let us know in Comments.
