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 will need to recall 323,700 diesel vehicles in India

Volkswagen Group's diesel emissions scandal continues to spread, and now the automaker must recall 323,700 diesel vehicles in India because of too much pollution, according to Bloomberg. The campaign covers models from several of the group's brands including VW, Audi, and Skoda. The Automotive Research Association of India first discovered the emissions irregularities after conducting its own real world and lab tests, and the Indian government then commanded VW to explain what was happening. The country's regulators will allow the automaker to set the recall schedule for the repairs, according to a government official who spoke to Bloomberg, and the campaign will likely happen in phases. Among the affected vehicles, there will be about 100,000 from the VW brand including the Jetta, Passat, and some variants of the Polo. VW already has repairs for some of the affected diesel engines in Europe, and the company can allegedly fix the emissions problem with new software and small hardware changes. The situation is harder in the US where regulators still need to approve any proposed solutions, and VW also must now recall its 3.0-liter V6 TDI in California to eliminate other problematic code. The German automaker faces investigations from regulators all over the world into its emissions evasions, and they could be quite costly. One estimate already suggests the minimum price of the potential repairs, fines, and other expenses at about $24.5 billion. Officials in Brazil have already fined the company $13 million for pollution issues with the diesel Amarok pickup and requested a recall to fix them.

VW Golf Sportsvan succeeds Golf Plus in Frankfurt

Just ahead of this week's Frankfurt Motor Show, Volkswagen has announced the world premiere of its Golf Sportsvan, a near-production concept that succeeds its Golf Plus. VW describes this compact family car as "one of the most versatile vehicles of the compact class," noting that it offers a mix of hatchback and minivan features in a sporty package.
That sportiness comes from the Sportsvan's styling (perhaps more sleek wagon than minivan) and performance features it shares with the Golf GTI - including the XDS+ electronic differential lock, which is integrated into the Electronic Stability Control system to improve agility. At the same time, the Sportsvan's six engine options, which include a turbodiesel, are up to 19-percent more fuel-efficient than their predecessors.
