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.

Audi rumored to buy Alfa Romeo, officials deny it

For more than two years, Volkswagen has been making public statements about its willingness to buy Alfa Romeo and quadruple the Italian brand's sales, and for just as long, Fiat CEO Sergio Marchionne has replied with some version of "Mr. Piëch, drop it." According to a report in Ward's Auto, all that jousting might be over: it claims that sources close to both Marchionne and Audi CEO Rupert Stadler admit that the two are in talks for Audi to buy not just Alfa Romeo, but a production plant in Italy. In fact, a final deal could possibly include partsmaker Magnetti Marelli.
Against that backdrop, a report by German news weekly Stern quotes a Fiat spokesmen as saying it doesn't comment on rumors and an Audi rep has said flatly that "There is no substance in the news." If a sale is being arranged, the timing would seem to point to how eager Fiat is to raise cash to complete its major initiatives. Even though Alfa Romeo continues to delay its return to the US, it just showed off the production version of the 4C at the Geneva Motor Show (shown above) and said that preferred Fiat dealerships here would get them. Then there's Alfa's recently concluded deal with Mazda to develop a roadster based on the next generation MX-5 Miata - a deal that would seem to help both the Italian and Japanese brands.
The monetary issues are troublesome, though. Fiat is taking a beating in the European market and its weak-kneed balance sheet is delaying gotta-have-it products like the Jeep Cherokee. Fiat has been talking to banks about getting money to buy the rest of Chrysler and those financial institutions have also raised issues about debt and cash reserves, and the nasty game of chess Fiat is playing with the United Auto Workers (and now the court system about the portion of Chrysler it doesn't own) could end up blowing another hole in Marchionne's plans. It is possible that this could finally have convinced Fiat to at least see how serious Audi's parent company, Volkswagen, is about buying Alfa Romeo. Or it could be just another rumor.

Volkswagen E-Co-Motion Concept brings electric mobility to the commercial set

Volkswagen sees a future where the bulk of the world's freight is moved into city centers by train, then offloaded onto a fleet of smaller, light-duty commercial vehicles for final delivery. Those vehicles could wind up looking something like the company's E-Co-Motion Concept that debuted at the 2013 Geneva Motor Show. The EV features a modular underfloor drive unit comprised of a battery, motor and gearbox that can be paired with any number of cab and body configurations to suit a buyer's needs, from a refrigerated box to a standard flat bed.
The E-Co-Motion Concept features a rear-mounted electric motor with 113 horsepower and 199 pound-feet of torque. A standard 20 kWh battery pack provides a driving range of up to 62 miles, while 30 kWh and 40 kWh packs could deliver 93 and 124 miles of travel, respectively. Check out the press release below for more information.
