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 Beetle special edition concepts hit NY [w/poll]

Buying a retro hatchback or convertible like a VW Beetle is nothing if not a fashion statement, and nobody knows that better than Volkswagen itself. Which is likely why the German automaker is bringing four concept versions of the Bug to the New York Auto Show this year. Most intriguing of the quartet – to our eyes at least – is the Beetle R-Line concept, which takes a more performance-oriented approach. It's got 20-inch alloys riding on a wider track, an aero pack including a rear diffuser and spoiler, and black trim that looks great in contrast to the white pearl finish. The interior has been upgraded, as well, with sport buckets, carbon trim and yellow details, and the concept is powered by the 2.0-liter TSI engine with 217 horsepower. The R-Line concept won't be taking the stage alone, however, joined as it will be by the magenta-sprayed Pink Color Edition hatch, the beach-themed Wave and jeans-wearing Denim edition convertibles. Though all are billed strictly as showcars for the time being, VW admits it will be gauging public reaction to all four to determine potentially putting them into production for public consumption. So, that in mind, have a look at all the concepts in the gallery above, and tell us which one you like best in the poll below.

VW to announce $1B investment in Mexico plant

Big news south of the border could be slated for later this week, as Automotive News is reporting that the Volkswagen Group will announce a $1-billion investment in the company's Puebla factory. The company officially declined to comment, but AN is claiming the investment in the Puebla facility, which has been operating for over five decades, will add 1,900 jobs to the nearly 16,000-strong workforce. According to AN, a person familiar with the situation in Puebla claims the investment will support production of the next-generation Tiguan, slated to arrive in 2017. The Puebla factory currently produces Golf, while total output last year nearly hit half a million vehicles, or about 15 percent of Mexico's total automotive output.
