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.

Former Audi chief designer Wolfgang Egger leaves Italdesign

The latest word from the international community of automotive designers has it that Wolfgang Egger is leaving Italdesign, but just where the accomplished designer will land next and who will take his place remain big question marks. Egger is a designer who has bounced back and forth between Italy and Germany over the course of his career. He was born in Germany but studied in Milan. He began his career at Alfa Romeo in 1989 and was named its chief designer by 1993 before being head-hunted by the Volkswagen Group in 1998 to head up the design department at Seat. A few years later he went returned to Italy to run the Lancia design department, and was subsequently renamed to the same post at Alfa Romeo. In 2007 he went back to his native Germany to head up the Audi design office, over which he assumed complete responsibility by 2012, but left Audi in 2013 to run Italdesign. For those unfamiliar, Italdesign is the studio founded by Giorgetto Giugiaro (pictured at left next to Egger) back in 1968 but which, along with many other Italian design houses, fell on hard times in recent years. The Volkswagen Group swooped in to rescue the troubled studio in 2010, turning it into something of an in-house advanced design department to provide an alternative perspective on the direction in which the group and its various brands could take their respective designs moving forward. With Egger now leaving its helm, Italdesign and its German parent company will need to find his replacement, and we're sure they'll announce one in due course. The bigger question on our minds, however, is where Egger himself will head next. Given the path his career has taken to date, we wouldn't be surprised to see him land elsewhere in the Volkswagen Group or find a new role in the expanding Fiat Chrysler Automobiles empire. Then again, Egger could find it time to open an entirely new chapter. Watch this space.

Honda, Mazda, Mitsubishi, Mercedes also under diesel emissions scrutiny

The controversy over Volkswagen's diesel emissions scandal isn't limited to the US. In Europe, where diesel engines are far more popular, the issue is shining a harsh light on the NEDC emissions test. As already known, the evaluation does a poor job of reflecting real-world production of NOx, and it appears a significant number of automakers are affected. The Guardian in the UK has been reporting on real-world test results from a company called Emissions Analytics. After the latest round of checks, vehicles from Mercedes-Benz, Honda, Mazda and Mitsubishi were found to generate far more NOx than they should. The newspaper also published similar results for Renault, Nissan, Hyundai, Fiat, Volvo, Jeep, Citroen, VW, and Audi. On average, the figures are about four times over the limit of producing the pollutant. Unlike VW and its defeat device, these automakers aren't actually breaking the rules. The vehicles perform up to the NEDC lab test for emissions, but those results simply aren't translated to the street. "The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions," Nick Molden from Emissions Analytics said to The Guardian. A big fight to decide the future of this issue appears to be on the horizon. Automakers claim that they can't meet the next round of tightening emissions regulations and are asking for compromises. Although, spokespeople for Mercedes and Honda told The Guardian that the brands would be in favor of the stricter rules. Meanwhile, some European governments began backtracking their support of diesels well before this scandal came to light. The added scrutiny certain hasn't helped the future of the oil-burner.
