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.

$1.4B hedge fund suit against Porsche dismissed

Investors have canvassed courts in Europe and the US to repeatedly sue Porsche over its failed attempt to take over Volkswagen in 2008 (see here, and here and here), and they have repeatedly failed to win any cases. You can add another big loss to the tally, with Bloomberg reporting that the Stuttgart Regional Court has dismissed a 1.4-billion euro ($1.95B US) lawsuit, the decision explained by the court's assertion that the investors would have lost on their short bets even if Porsche hadn't misled them.
Examining the hedge funds' motives for stock purchases and the bets that VW share prices would fall, judge Carola Wittig said that the funds didn't base their decisions on the key bits of "misinformation," and instead were participating simply in "highly speculative and naked short selling," only to get caught out.
With other cases still pending, the continued streak of victories bodes well for Porsche's courtroom fortunes, since judges will expect new information to consider overturning precedent. If there is any new info, it could come from the potential criminal cases still outstanding against former CEO Wendelin Wiedeking and CFO Holger Härter, who were both indicted on charges of market manipulation.

Volkswagen adding R-Line trim to Touareg, Tiguan for 2014

Volkswagen introduced its aggressive R-Line appearance package on the CC and Beetle last year, but later this year, this treatment will also be applied to VW's crossovers, the Tiguan and Touareg. Both sporty-looking utility vehicles will be unveiled next week at the Detroit Auto Show.
The 2014 Tiguan R-Line comes standard with bi-xenon headlights and LED daytime running lights, and the package adds 19-inch wheels, grey fender extensions, body-color side skirts and a liftgate spoiler. Inside, the R-Line adds a flat-bottom sport steering wheel with paddle shifters, a black headliner and numerous metallic trim accents such as the stainless scuff plates, the aluminum pedals and metallic finish on the instrument and door panels. The Tiguan R-Line will be offered in front- and all-wheel drive configurations.
As for the 2014 Touareg R-Line (shown above), this model gets an ever more distinctive look with an aggressive front fascia, 20-inch wheels and dual oval-shaped exhaust outlets in addition to the painted side skirts and LED taillights. Similar metallic interior trim pieces found inside the Tiguan R-Line will also make their way into the Touareg as well as gloss black accents on the instrument panel and center stack.
