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 budget sub-brand stuck in limbo over VW standards, costs

Reports in October 2012 claimed Volkswagen had begun investigating the creation of its own budget brand. This came after having failed to purchase Malaysian car company Proton or produce a meaningful partnership with Suzuki, and after watching Renault-Nissan make piles of euro on Dacia and plot the return of Datsun.
For VW, more important than the question of what to call it was how to build it profitably and in a way that didn't damage the VW brand. According to a report in Autocar, a satisfactory answer still hasn't been found. The hurdle is how to hit "'necessary' quality and safety levels" at the price points needed to make the venture worthwhile. At the time of the 2012 report, German outlet Der Spiegel said VW was trying to get prices down to 6,000 to 8,000 euro ($7,784 to $10,379 US), about two thousand to four thousand euro under the price of the VW Up and in line with the cost of a 6,790-euro Dacia Sandero in Germany.
In March 2013, VW announced, "We want to bring a true budget car to the market in China in the foreseeable future," the most concrete move in that direction after years of planning to make a decision. Working with local Chinese maker FAW, it was predicted that the vehicle in question would appear around 2016, but as of November last year a final vote on it needed to wait until this year because "We are still working on the cost side" and profit possibilities for a car that "has to be durable, it has to be precise, it has to be safe."

Audi RS3 and Volkswagen Golf R face off in Evo test

Typically when an automotive publication pits two rivals against each other, they come from different companies. After all, why would one automaker – even one parent company – develop two distinct models to compete against each other? Well, the Volkswagen Group isn't like most. It pits Porsches against Lamborghinis, Audis against Bentleys, Seats against Skodas... all under the same roof. In the high-powered hot hatch market, it offers both the VW Golf R and the Audi RS3. The question is, which is the better drive? Evo put them both on track for a quick bout of sibling rivalry to find out. On paper it would seem like an unfair fight. Sure, both are based on the same platform and channel their power to the tarmac through all four wheels. But the Audi's five-cylinder engine packs considerably more muscle than the Golf's four: 362 horsepower and 343 pound-feet of torque trump 296 hp and 280 lb-ft. There's just no way around that – at least until the Golf R 400 comes along. The Audi, as you might have guessed, also costs substantially more than the Volkswagen. But that's not Evo's concern here. This is a cost-no-object, bare-knuckle throw-down. Watch the ten-minute video above to find out if the cheaper, less powerful Golf R can keep pace with its more upscale and brawnier brother.
