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.

Honda wins Commercial of the Decade, but not for the ad you think [w/VIDEO]

Honda's Commercial of the Decade: "Grrr" - Click above to watch video
The mad men at Adweek recently voted for the Commercial of the Decade (Super Bowl commercials not included) and Honda took top honors over memorable ads from the last ten years by companies like Nike, Budweiser and Sony. That's not a big surprise considering Honda often puts a huge amount of effort into its on-air spots. However, the Japanese automaker didn't win for the commercial you might have expected: "Cog." Though Honda's famous commercial that breaks down a European Accord Tourer into a Rube Goldberg-esque machine was also a finalist, it was beaten by another Honda commercial called "Grrr" that's narrated by Garrison Keillor of all people. You've probably never seen it, but you can after the jump.
Volkswagen also made the list of finalists, but the particular ad chosen out of all the comical VW ads we've seen was unexpected as well. Most surprising carmaker with a commercial in the finals: Saturn. Who knew...

Volkswagen Golf R Evo may debut at Beijing Motor Show

If a report in Auto Express is correct, a lighter, faster brother to the Volkswagen Golf R will be shown to the world at the Beijing Motor Show in April. Said to be called the Golf R Evo, the even harder hot hatch would be unveiled as one of those concepts that's practically a de facto presentation of the genuine thing. The Evo in its name will come from having a carbon fiber roof and CF in the bodywork, lighter wheels, thinner bucket seats up front and a roll cage instead of rear seats.
If there's a power increase, it's been described as "a small bump." However, as the report mentions, if the Jenny Craig regimen can drop 100 kilograms (220 pounds) from the the 3,247-pound weight of the European Golf R, then the Golf R Evo will do about the same damage on the scales as the Golf but have at least 50 more horsepower and 44 more pound-feet of torque.
Since we still don't have the current Golf, this isn't something that should keep you awake even if the 'concept' does become a production model. But it is good to know that the Golf R is really going to start pushing its boundaries.
