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.

J.D. Power customer survey of dealers counts Cadillac, Buick as big winners

Cadillac and Buick have taken the trophies in J.D. Power's latest Customer Service Index Study examining satisfaction with dealer service. Surveying more than 90,000 owners and lessees of 2009-2013 model-year cars, the study found that those with pre-paid maintenance packages were ten percent more likely to buy their next car from the same brand.
Dealer satisfaction scores have improved overall, Cadillac nabbed the luxury segment ahead of Audi and Lexus, taking the crown that Lexus held last year. Buick keeps the mass-market dealer satisfaction win in the family, finishing ahead of Volkswagen and last year's winner GMC. The study also found that service department use of tablets increased customer satisfaction, as did "best practices" like "providing helpful advice." Who knew?
You can find details on those and more findings in the press release below.

VW GTI Clubsport Concept celebrates model's 40th birthday with 261 hp

Volkswagen is celebrating the four-decade milestone for the GTI with the world debut of the GTI Clubsport concept at the annual Worthersee festival in Austria. While the version in these sketches is just a prototype, European buyers at least are set to get a production model in early 2016. The Clubsport is essentially a way for VW to split the difference between the already well-liked GTI and the hotter Golf R. In concept form, it packs 261 horsepower, compared to 220 hp from the standard version in the US with the Performance Package or 292 hp from the R. A temporary overboost function even lets the Clubsport make about 10 percent more power for short periods. Beyond just the mechanical upgrades, the concept in these sketches also wears a revised lower air dam at the front with a mesh grille and big strakes at the corners, and there's a new roof spoiler and rear diffuser at the back. VW also promises a more "individualized" interior. Unfortunately, the North America might not be getting this more powerful GTI. "There are no plans to bring the car to the US currently," VW spokesperson Mark Gillies told Autoblog. At this time, VW only has info about the Clubsport in German, which you can take a look at below. Related Video: Weltpremiere des Golf GTI Clubsport am Worthersee Exklusives Jubilaumsmodell zum 40. Geburtstag des GTI Golf GTI Clubsport debutiert mit 265 PS und Boost-Funktion Im kommenden Jahr feiert der Golf GTI seinen 40. Geburtstag. Volkswagen wird dieses historische Ereignis mit einem progressiven Jubilaumsmodell adeln: dem neuen Golf GTI Clubsport. In Form einer seriennahen Studie wird Volkswagen den Golf GTI Clubsport bereits am 14. Mai 2015 als Weltpremiere im Rahmen des legendaren GTI-Treffens am Worthersee prasentieren. Mit einer Leistung von 195 kW / 265 PS (plus 35 PS gegenuber dem Golf GTI Performance*) sowie einer temporar dank Boost-Funktion nochmals um rund 10 Prozent hoheren Spitzenleistung soll der Golf GTI Clubsport Anfang 2016 als der bis dato starkste jemals in Serie gebaute „GTI" durchstarten. Das Jubilaumsmodell wird nicht nur mit einem extrem leistungsstarken Motor, sondern mit einem individualisierten Interieur und exklusiven Karosseriedetails auf den Markt kommen. Zu den Design-Modifikationen gehoren ein komplett neuer Frontstoss-fanger, neue Seitenschweller, ein ebenfalls neuer und aerodynamisch hoch innovativer Dachkantenspoiler sowie ein eigens entwickelter Heckdiffusor.
