VW bringing fuel cell concept to LA Auto Show

Amid the flurry of hydrogen announcements from Toyota and Honda last night, Volkwagen has something to add: a new hydrogen fuel cell concept vehicle. This will be the first VW hydrogen fuel cell vehicle in many years – remember the Tiguan Hy-Motion back in 2008? – and it comes as a bit of a surprise. First written up by the German publication Wirtschaft Woche, VW is going to have the prototype car (not pictured) available at the ride and drive at the Los Angeles Auto Show later this week. We don't yet know what kind of vehicle will sport the hydrogen powertrain, but our money's on a Golf variant. We'll see soon enough when we get to Los Angeles. What's interesting is that there have been a number of not-so-mixed messages out of the VW executive ranks when it comes to hydrogen vehicles. VW's Japanese president, Shigeru Shoji, said in September that, hydrogen fuel cells, "may fly within Japan, but not globally." Last year, VW's electrification head Rudolf Krebs said that "hydrogen mobility only makes sense if you use green energy." Also last year, VW CEO Martin Winterkorn said it's basically impossible to build hydrogen vehicles at a "reasonable cost." Nonetheless, we're going to see a new VW H2 concept soon. Thoughts?

Volkswagen Golf R 400 Concept still makes us swoon

We know, we know – this hot little guy isn't really new or anything. Volkswagen first rolled out the Golf R 400 concept in Beijing earlier this year, and since its debut, we've heard rumors that the German automaker might-perhaps-maybe-hopefully build the thing. Its showing here in Los Angeles simply marks the first time it's debuting in America, and honestly, we can't get enough. So here it is, again. Hello, Golf R 400 – we love you. And what's not to love? What starts as a normal Golf R gets better with a more aggressive appearance, big wheels, some tasteful neon yellow accents, and a whole mess of power. The original concept packed 395 horsepower from an overblown 2.0-liter turbo-four, though the most recent reports suggest a production version could produce over 400 hp. To keep it all in line, the concept has all-wheel drive. And inside, it's the same functional, comfortable Golf we've always loved. There's nothing left to say, really. We love this car, and you should, too. Check it out in the gallery above.

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.
