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 Group, BMW Z4 top Total Value Awards by Strategic Vision

It was just nine months ago that Strategic Vision announced its 2011 Total Value Awards, but you don't have to wait until next year for the 2012 awards. The Volkswagen Group keeps its lead as the number one brand, with seven products taking top category spots: Golf, Jetta Wagon, CC, Eos and Audi A3 Wagon, Q5 and Q7. Strategic Vision says "true innovation" - "rich and impactful, intuitive, motivational, in-depth and is able to trigger description by the user in great specificity" - is the open secret of the brands with the strongest showings. Results are culled from 77,153 owners covering more than 350 new cars bought between September of 2011 and 2012 ranked in the Total Value Index (TVI).
Other notable winners are Hyundai-Kia following VW in the brand category and having the Hyundai Elantra and Kia Sorento among category winners, the BMW Z4 taking the premium roadster category and the highest overall score of any vehicle, the Chevrolet Volt continuing to gather silverware in the Special Category, nabbing the second-highest score of all and representative of "nearly perfect innovation," and Chrysler and Dodge being most improved.

European jury picks finalists for 2015 Car of the Year

There are countless Car of the Year awards handed out each year, and naturally, Europe has its own way of doing things. Every year, a panel of jurists representing seven publications in seven different languages and seven different countries get together to name their joint Car of the Year. The panel released a list of 32 candidates back in July, and it has now whittled that list down to seven nominees. The list consists of the BMW 2 Series Active Tourer, the Citroen C4 Cactus (shown), the Ford Mondeo, the Mercedes-Benz C-Class, the Nissan Qashqai, the Renault Twingo and the Volkswagen Passat. Of those seven, only two are available in the US – those being the Mondeo (sold Stateside as the Fusion) and the C-Class. The Passat is an entirely different model in North America, the Qashqai isn't offered here, Citroen and Renault don't even participate in our market and the BMW 2 Series is represented here only by the completely different coupe and convertible. Expect the one and only recipient of the 2015 Car of the Year award to be announced at the Geneva Motor Show this coming March, and while you're waiting, you can place your guesses for the eventual winner in Comments.
