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 1.1M Jetta, Beetle models in US, China over suspension fears

Volkswagen is recalling about 1.1 million vehicles in China and North America in a newly announced campaign affecting the rear suspensions on some models. For the US, the action covers about 442,265 vehicles, including 400,602 examples of its 2011-2013 Jetta and 41,663 units of the 2012-2013 Beetle and Beetle Convertible. According to Reuters, the recall affects a further 126,000 vehicles in Canada and about 581,090 in China, including related market-specific models like the Sagitar.
The problem can occur if the affected models have a collision to the rear or the side-rear of the vehicle. It's then possible for the trailing arms on the torsion-beam rear suspension to be damaged. If the harm isn't noticed, then the part could fracture while driving. Obviously, a broken rear suspension is going to have an adverse effect on handling.
To fix things, VW dealers will inspect the trailing arms on the models, and they will all receive a sheetmetal part that will make a distinctive sound if broken in the future. If already damaged, the entire torsion beam will be replaced. Obviously, this work will be done at no charge to owners.

Volkswagen Golf, Ford F-150 named 2015 North American Car and Truck/Utility of the Year

Congratulations, Volkswagen Golf/GTI and Ford F-150. You've just been named the 2015 North American Car and Truck/Utility of the Year, kicking off the first press day of the Detroit Auto Show. The Golf faced some seriously stiff competition from its runners-up, the Ford Mustang and Hyundai Genesis. But the Golf has been a highly awarded vehicle since its launch, including recently being named Motor Trend's Car of the Year. As for the Truck/Utility award, it wasn't immediately clear that the aluminum-bodied Ford F-150 would win the North American honor, topping the Chevrolet Colorado and Lincoln MKC. The Chevy, after all, has been widely praised since arriving this fall, including taking home MT's Truck of the Year award. In 2014, Chevrolet had a sweep of the NACTOY awards, with the Corvette Stingray and Silverado taking top honors. Here's a look at the 2015 North American Car and Truck/Utility of the Year voting breakdown. As you can see, it wasn't exactly neck and neck. Car of the Year Volkswagen Golf/GTI – 256 points Ford Mustang – 204 points Hyundai Genesis – 110 points Truck/Utility of the Year Ford F-150 – 297 points Chevrolet Colorado – 205 points Lincoln MKC – 68 points The winners were determined by the votes of 57 North American jurors who work in all forms of media – magazine, newspaper, television, online and radio, and their ballots were tabulated in secret by accounting firm Deloitte & Touche. Autoblog editors Sharon Carty and Chris Paukert are members of the North American Car and Truck/Utility of the Year jury.
