U.S. opens probe into whether VW vehicles infringe Jaguar Land Rover patents

WASHINGTON — The U.S. International Trade Commission (ITC) said on Monday it is opening in investigation into whether Volkswagen AG infringed on patents held by Jaguar Land Rover for a system used for off-road driving. In November, Jaguar Land Rover, a unit of Tata Motors, filed a complaint with the ITC seeking to prevent the import of some VW Porsche, Lamborghini and Audi models with "certain vehicle control systems" that allegedly infringe on it patents held for its Terrain Response system. The models include the Lamborghini Urus, Porsche Cayenne and AudiÂ’s Q8, Q7, Q5, A6 Allroad, and E-Tron vehicles and the VW Tiguan. The ITC said it has made no decision on the merits. VW said in a statement it was examining the action and determining its next steps. "We will of course cooperate with investigating authorities. While we cannot comment on any details of the proceedings, we strongly believe that the claims have no merit and will robustly defend our position," VW said. Many automakers offer a suite of off-road powertrain controls, but JLR claims Volkswagen's tech is more than just similar.  Jaguar Land Rover (JLR) said the vehicles "have used JLRÂ’s patented inventions without payment or permission" notably a patent for an "improved system for driving a vehicle on different driving surfaces, in particular off-road." JLR says its Terrain Response technology uses the patented technology to maximize performance on off-road driving surfaces, including grass, snow, mud, sand and rocks.

Former Porsche execs acquitted of stock manipulation charges

A German court acquitted former Porsche CEO Wendelin Wiedeking and former CFO Holger Harter of stock manipulation charges, according to Bloomberg. Prosecutors alleged the men hid plans to takeover Volkswagen while publicly denying their intentions to investors. The presiding judge didn't find any merit to those claims, though. "There is nothing to the allegations, absolutely nothing," Judge Frank Maurer said, according to Bloomberg. "There was no secret plan to take over VW." Rather than Porsche taking over VW, the exact opposite eventually happened, and both execs stepped down. Investigators first indicted Wiedeking and Harter for alleged stock manipulation in late 2012. A court in Stuttgart dismissed the case in 2014 because of a lack of evidence, but an appeals court later overruled that decision. The current trial finally began in October 2015. If convicted, Wiedeking faced up to 30 months in prison, and Harter could have received up to 27 months, Bloomberg reported. Prosecutors also wanted one million euro ($1.1 million) fines from them and 807 million euros ($910 million) from Porsche. The acquittal might not be the end of this long-running case, though. In Germany, prosecutors have the right to appeal a ruling, and the lawyer hasn't made a final decision yet. If the court thinks there's a reason, the former execs could be back in front of a judge at some point in the future.

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.
