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.

The super-sized Atlas isn't the three-row VW should build

In the late '50s and early '60s the Volkswagen Beetle wasn't ubiquitous in my hometown of Lincoln, Nebraska, but it came pretty damn close. Fords and Chevys dominated, but beyond the occasional MG, Triumph, or Renault the import scene was essentially a VW scene. When my folks finally pulled the trigger on a second car they bought a Beetle, and that shopping process was my first exposure to a Volkswagen showroom. For our family VW love wasn't a cult, but our '66 model spoke – as did all Volkswagens and most imports at the time – of a return to common sense in your transportation choice. As VW's own marketing so wonderfully communicated, you didn't need big fins or annual model changes to go grab that carton of milk. Or, for that matter, to grab a week's worth of family holiday. In the wretched excess that was most of Motown at the time, the Beetle, Combi, Squareback, and even Karmann Ghia spoke to a minimal – but never plain – take on transportation as personal expression. Fifty years after that initial Beetle exposure, and as a fan of imports for what I believe to be all of the right reasons, the introduction of Volkswagen's Atlas to the world market is akin to a sociological gut punch. How is it that a brand whose modus operandi was to be the anti-Detroit could find itself warmly embracing Detroit and the excess it has historically embodied? Don't tell me it's because VW's Americanization of the Passat is going so well. To be fair, the domestic do-over of import brands didn't begin with the new Atlas crossover. Imports have been growing fat almost as long as Americans have, and it's a global trend. An early 911 is a veritable wisp when compared to its current counterpart, which constitutes – coincidentally – a 50-year gestation. In comparing today's BMW 3 Series to its' '77 predecessor, I see a 5 Series footprint. And how did four adults go to lunch in the early 3 Series? It is so much smaller than what we've become accustomed to today; the current 2 Series is more substantial. My empty-nester-view of three-row crossovers is true for most shoppers: If you need three rows of passenger capacity no more than two or three times a year – and most don't – rent it forgawdsake. If you do need the space more often, consider a minivan, which goes about its three-row mission with far more utility (and humility) than any SUV.

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...
