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.

Volkswagen promises more aggressive design for sedans, crossovers

Every one of our Volkswagen Jetta and Passat reviews is guaranteed to include this word in the comments, aimed at its exterior design: "Boring." The brand says that's all about to change, telling a group of journalists during a tour of its design studio in Wolfsburg that designs will be more market specific; as Automotive News put it, that means "more aggressive" designs for the US that "will bare their teeth and flex their muscles," since the solid-yet-unoffensive look hasn't got VW past its two-percent market share here. Yes, we've heard this before from the Volkswagen Group - Audi has been promising to pump up the volume on its designs for years now, we're still waiting to hear that music. But VW brand head designer Klaus Bischoff says that the look of the coming midsize crossover that will come in around the size of the Audi Q7 "has to be bold. It has to be a statement," and the results of US focus groups have already dictated design changes to the original idea. AN said it takes cues from the Cross Coupe GTE, with a notched grille, sculpted hood, and deep character lines along the flanks. It sounds like baby steps for other models, though. The Passat gets a brand new design forward of the A-pillar, and new taillights. The new Tiguan has a shorter front overhang and a longer rear overhang, rounded wheel arches, and gets 2.2 inches longer. There'll be a long-wheelbase version of the Tiguan that grows by eight inches, which should give it livable room for four passengers in front and back. Beneath that will be a Golf-based crossover to compete in the compact segment with the Honda HR-V and Mazda CX-3.

Porsche 911 and Nissan 350Z get smoked by unlikely hero

So a Nissan 350Z Procharger and a current Porsche 911 GT3 drive onto the Autobahn together - stop me if you've heard this one before - and they decide to race. We're not sure how much power the Z is packing, but the stock model topped out at 306 horsepower on the last year of its run in 2009. And if that's a stock GT3 then it will be rocking something like 475 horsepower. So the Z and the GT3 give it a racing go, and just as one of them starts to pull away they're both overtaken by one of the most unlikely dark horses you could imagine. It's a really short video and we won't spoil the surprise, so check it out above.
