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.

Rimac inks deal to purchase 55% of Bugatti from VW Group

ZAGREB, Croatia — Croatian electric supercar builder Rimac is taking over the iconic French manufacturer Bugatti in a deal that is reported to be worth millions of euros. Rimac said GermanyÂ’s Volkswagen Group, including the Porsche division — which owns a majority stake in Bugatti — plans to create a new joint venture. The new company will be called Bugatti-Rimac. Rimac Automobili announced Monday that it will be combining forces with Bugatti to “create a new automotive and technological powerhouse.” Rimac has progressed in 10 years from a one-man garage startup to a successful company that produces electric supercars. Mate Rimac, who founded the company in 2009, says the venture is an “exciting moment” and calls the combination of the companies “a perfect match for each other.” Porsche will own 45% of Bugatti-Rimac while Rimac Automobili will hold the remaining 55% stake, according to Croatian media reports. Financial details of the deal were not published. Bugattis will continue to be assembled in eastern France, where the company was established in 1909. The vehicles will use engines developed and made in Croatia. “In an industry evolving at ever-increasing speed, flexibility, innovation and sustainability remain at the very core of RimacÂ’s operations," the company said. “Uniting RimacÂ’s technical expertise and lean operations with BugattiÂ’s 110-year heritage of design and engineering prowess represents a fusion of leading automotive minds."

North American production of foreign marques to jump in 2014

Wards Auto has released its North American Light Vehicle Production Forecast for 2014, and the report predicts foreign manufacturers will increase production on the continent some 3.9 percent by 2014. If accurate, that should see 123,000 additional cars, trucks and vans produced in North America, swelling the total number of units produced both by domestic and foreign manufacturers to 16.9 million light vehicles from a projected 15.6 million in 2013. Much of the increase can be attributed to the fact that Toyota intends to produce another car at its Blue Springs, MS plant as well as a new Lexus model at its Georgetown, KY facility in a year's time.
Likewise, Volkswagen intends to move production of a currently imported model to its plant in Puebla, Mexico. Daimler, Honda, Nissan and Mazda also plan to build additional models on North American soil for the first time. Around two-thirds of the new North American manufacturing will take place in Mexico, helping the country soak up a full 20 percent of the content's automotive production for the first time.
