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 LogBox and Race App performance data logger for R models [w/video]

Now that it's got a 300-horsepower Golf R to brag about, Volkswagen wants you to be able to brag about it accurately with the LogBox and Race App performance data logging combo. Plug the LogBox into your VW's OBD II port and it sends data over BlueTooth to the Race App, measuring variables like acceleration, distance, G-force and engine performance. If you're on a circuit, it uses Google Maps to make a map of the track, and you can record live video in-app to match with the data. Volkswagen says the LogBox will be available for R models and "a range of further Volkswagen cars," so you'll want to hit up your dealer with questions before ordering. It's available from the VW accessories store for 299 euros ($365 US), but right now the free app is only available in German, in the German-language iTunes and Google Play store. We imagine that will be corrected shortly; in the meantime, the video can show you how it works.

Volkswagen could outsell GM in China for the first time in nine years

As of the end of November, Volkswagen had sold 70,000 more cars than General Motors in China in 2013, making it appear inevitable that VW will outsell GM there. The feat would return the German brand to the top of chart in China for the first time in nine years, but even the second-place getter won't be complaining too loudly: both automakers sold more than three million vehicles in a market pegged to hit 16 million sales this year.
Volkswagen said it could have sold more cars if it had had more production capacity in China. The arrival of a new-to-China Audi A4, a China-built A3 sedan, the VW Bora and Skoda Octavia, as well as an $18.2-billion-euro investment in the country to construct new factories, means VW should see its numbers grow in 2014. GM's lineup is expanding next year, too, adding four Chevrolet nameplates and two vehicles to its Baojun brand as it tries to get to five million in sales by 2015.
Among other automakers, Ford benefited from good product and woes for Japanese automakers over a territorial dispute with China, outselling Toyota by almost 32,000 units through the end of November. The Ford Focus is China's best-selling vehicle so far this year.
