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 recalls another 6,700 vehicles over fuel leak [UPDATE]

UPDATE: An earlier version of this post suggested that the expanded recall involved an additional 44,658 units, when VW tells us that is in fact the total number - adding a further 6,679 to the original recall of 37,979. The text below has been updated accordingly, with our apologies for the confusion. It was a little over a month ago that Volkswagen issued a recall for some 38,000 vehicles over a potential fuel leak. Now the German automaker and the National Highway Traffic Safety Administration have expanded that recall, affecting even more vehicles for the same issue. The problem revolves around a sealing cap at the fuel rail, which could fail and cause fuel to leak into the engine compartment, thereby increasing the risk of a fire. This time around, VW is calling in a selection of Jettas, Passats, Golfs, GTIs, Beetles and Beetle Convertibles, all of them from the 2014 and 2015 model years (except the Golf and GTI, of which only 2015 models are being recalled). The recall now affects an estimated additional 6,679 units, which (in addition to the 37,979 recalled previously) brings the total up to 44,658 vehicles across the United States. RECALL Subject : Fuel Leaking Into Engine Compartment Report Receipt Date: JAN 23, 2015 NHTSA Campaign Number: 15V028000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 44,658 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2014-2015 Jetta vehicles manufactured March 28, 2014, to November 24, 2014, 2014-2015 Passat vehicles manufactured April 7, 2014, to November 18, 2014, 2015 Golf and GTI vehicles manufactured July 1, 2014, to November 20, 2014, and 2014-2015 Beetle and Beetle Convertible vehicles manufactured March 31, 2014, to November 27, 2014. A sealing cap at the fuel rail may fail, allowing fuel to leak into the engine compartment. CONSEQUENCE: A fuel leak, in the presence of an ignition source, can result in a vehicle fire. REMEDY: Volkswagen will notify owners, and dealers will replace the fuel rails with new parts, free of charge. The recall is expected to begin in early February 2015. Owners may contact Volkswagen customer service at 1-800-822-8987. Volkswagen's number for this recall is 24BL. Note: This recall expands and supersedes recall 14V-809 (Volkswagen recall number 24Bi) and only affects vehicles not previously repaired under that campaign.

VW Group recalls 27k Touaregs, Audis and Porsches for fuel leak

The Volkswagen Group is one of the most expansive in the entire industry, and shares parts across more product lines than we could wrap our heads around. So when the German megalith finds a fault in one of its components, it has the capacity to spread like wildfire. The latest set of recall notices from the National Highway Traffic Safety Administration covers vehicles from the Volkswagen, Audi and Porsche divisions. The problem revolves around the fuel injection system, which could potentially leak and cause a fire. The recall affects – deep breath now – the 2012 VW Touareg Hybrid, the 2011-12 Porsche Cayenne S Hybrid and Panamera S Hybrid, 2011-12 Audi S4, S5 and Q7 and the 2012-13 Audi A7. All told, that amounts to 27,376 units, the owners of which can expect to hear from the manufacturer to have the fuel rails replaced, along with their corresponding seals (having nothing to do with marine mammals writing letters). RECALL Subject : Fuel Injection System Fuel Leak Report Receipt Date: JAN 20, 2015 NHTSA Campaign Number: 15V019000 Component(s): FUEL SYSTEM, GASOLINE Potential Number of Units Affected: 26,008 Manufacturer: Volkswagen Group of America, Inc. SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2011-2012 Audi S4, S5, Q7, 2012 Audi A6, Volkswagen Touareg Hybrid, and 2012-2013 Audi A7 vehicles. In the affected vehicles the fuel injection system may experience a fuel leak. CONSEQUENCE: A fuel leak in the injection system in the presence of an ignition source, increases the risk of a fire. REMEDY: Volkswagen will notify owners, and dealers will replace the fuel rails and corresponding seals, free of charge. The recall is expected to begin March 10, 2015. Owners may contact Audi customer service at 1-800-822-2834 or Volkswagen customer service at 1-800-893-5298. Volkswagen's numbers for this recall are 24AP for Audi customers and 24BK for Volkswagen customers.
