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 says it has sold over 100,000 TDI diesels in America this year

Volkswagen Group of America has lit oil-burning fireworks to celebrate the sales of more than 100,000 TDI Clean Diesel vehicles in the US between its VW and Audi brands this year. According to VW, that means it is responsible for more than 75 percent of diesel-engined cars and SUVs sold here - perhaps not surprising when the two brands offer a total of 12 diesel models.
What might be surprising is that the number of diesels isn't far off the estimated sales of 90,000 battery electric vehicles and PHEVs, with 15,000 of those accounted for by the Tesla Model S, another 12,000 or so being the Toyota Prius PHEV.
VW's keen to play up the ease of making diesel part of your life, stressing that it doesn't need any change to the refueling infrastructure and that "this is a technology delivering real answers to society's concerns about fuel consumption and greenhouse gas emissions without compromises."

Volkswagen Passat gets Wolfsburg Edition, priced from $23,495*

Volkswagen has just announced a new Passat Wolfsburg Edition, which slots between the base S and mid-grade SE trims in terms of content and price. The automaker has not released any official photos of the car as of this writing (aside from the badge shot you see here, of course), but the Wolfsburg Passat will be visually set apart from the rest by a unique set of 16-inch alloy wheels.
The big host of upgrades for the Wolfsburg Edition are found inside, where buyers will enjoy standard amenities like leatherette seats (with bun-warmers on the front chairs), a power driver's seat, satellite radio and a media interface with iPod connectivity. Of course, this comes on top of the already standard Passat features like Bluetooth and auto on/off headlamps. The Wolfsburg Passat will only be available with the 2.5-liter five-cylinder engine and a six-speed automatic transmission.
Look for the 2013 Wolfsburg Edition Passat to hit dealerships in the very near future, priced from $23,495, *not including $795 for destination. Have a look below for Volkswagen's official press blast.
