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 of America boss Horn was aware of diesel cheat 18 months ago

We're just going to make a prediction: Volkswagen of America boss Michael Horn's congressional testimony, slated to begin today, is not going to go well. Based on a written testimony submitted by Horn, the exec is expected to tell Congress he knew his company was violating emissions regulations at least 18 months before it actually came clean. "In the spring of 2014... I was told that there was a possible emissions non-compliance that could be remedied," Horn wrote, in testimony published on the US House of Representatives' website (PDF warning). "I was informed that EPA regulations included various penalties for non-compliance with the emissions standards and that the agencies can conduct engineering tests which could include 'defeat device' testing or analysis. I was also informed that the company engineers would work with the agencies to resolve the issue." Horn's written testimony went on to outline how the company will "develop a remedy for our customers." It includes five points, ranging from the "world-wide investigation" being conducted by the company to reassurances that VW's engineers are "working tirelessly" on fixes to the four-cylinder diesel problems. Horn went on to confirm that each generation of the affected diesel – there are three – will require its own distinct fix. Finally, Horn went on to say that the company will "examine our compliance, processes, and standards" to prevent a repeat of the diesel catastrophe, while promising "open communication with our customers, dealers, employees, and the public as we move forward." We've included Horn's complete, three-page written testimony below. Have a look. Testimony of Michael Horn, President and CEO of Volkswagen Group of America, Inc. Before the House Committee on Energy and Commerce Subcommittee on Oversight and Investigations October 8, 2015 Chairman Upton, Chairman Murphy, Ranking Member Pallone, Ranking Member DeGette, other Members of the Committee, thank you for inviting me to testify before the Committee today. My name is Michael Horn, and I am the President and CEO of Volkswagen Group of America, a subsidiary of Volkswagen AG, headquartered in Wolfsburg, Germany. I have volunteered to come before this Committee at the very outset of these inquiries in an effort to show our commitment to cooperation. We have not had the opportunity to review all aspects of this matter, indeed the investigation is just beginning.

VW Scirocco is the car nerd's classic car

Petrolicious undoubtedly makes some fantastic videos, but it often focuses on expensive, rare vehicles that many people might not be able to afford for their garage. This week the spotlight shifts to a modern coupe that's fairly accessible: the Volkswagen Scirocco. Owner Jason Cammisa is a senior editor at Road & Track, and his job puts him behind the wheel of some of the world's fastest supercars. Despite that, he has kept driving this 16-valve Scirocco that he has owned since college. The Scirocco is an easy car to love, though. Its simple, angular lines still look beautiful on the road today. While the four-cylinder engine doesn't make huge power, the coupe is nimble and ideal for a drive over twisty roads. Cammisa also makes an interesting point about owning affordable classics like this. Without a wealthy owner base like those that support vintage Corvettes or Porsches, there's little desire in the aftermarket to produce spare parts for his Scirocco. He worries about keeping the VW on the road decades into the future. For now, enjoy this '80s coupe thanks to this great clip from Petrolicious.
