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.

CEO says Volkswagen's buying spree is over

After adding Italian motorcycle icon Ducati to its stable and spending $5.6 billion on the rest of Porsche, Volkswagen CEO Martin Winterkorn says he's done shopping for a while.
"We have enough to do at the moment in taking our twelve brands to where we want to be," Winterkorn tells German newspaper Handelsblatt.

Volkswagen rolls out all-new Polo R WRC

Volkswagen may have ruled out producing a road-going Polo more potent than the new GTI, but on the rally stage, the Polo R WRC has proven absolutely dominant. Introduced to the World Rally Championship in 2013, the Polo R won ten out of the baker's dozen rallies in its debut season, and all but one last year to win both titles two years running. That's quite an act to follow, and the task falls to the machine you see here. The new second-generation Polo R WRC was just revealed at Autostadt in Wolfsburg. The rally machine has been substantially reworked for 2015, with a new livery, new bodywork and new oily bits. In fact, Volkswagen says it has revised three quarters of the components, and while it has not yet detailed the "many new ideas [implemented] under the bonnet," it has identified the hydraulic gearbox as "the biggest innovation." Further details are still to come, but this is our first look at the new machine with which Sebastien Ogier, Jari-Matti Latvala and Andreas Mikkelsen – who finished last year's championship in first, second and third, respectively – will tackle this year's championship, starting with the Rally Monte Carlo on January 22-25. FIA World Rally Championship (WRC) New technology, new design: presenting the second generation Polo R WRC - World premiere of the 318-hp Polo R WRC in Wolfsburg - Member of the Board, Dr. Heinz-Jakob Neusser, launches title defence - WRC kicks off with the iconic Rally Monte Carlo from 22–25 January Wolfsburg (15 January 2015). In top form, both technically and visually: Volkswagen presented the second generation of the Polo R WRC in Autostadt, Wolfsburg. The works team from Wolfsburg has its sights set firmly on another successful defence of its titles in the FIA World Rally Championship (WRC) with a new car and a new look. Volkswagen completed a clean sweep of all the World Championship titles when the Polo R WRC made its debut in 2013, before repeating this impressive feat last season. Continuity is the key to the driving line-up for 2015: double world champions Sebastien Ogier/Julien Ingrassia (F/F) and team-mates Jari-Matti Latvala/Miikka Anttila (FIN/FIN) and Andreas Mikkelsen/Ola Floene (N/N) will roll down the starting ramp and head onto the first special stage of the year for Volkswagen at the legendary Rally Monte Carlo on 22 January. "The new Polo R WRC has undergone intense further development, both on the inside and the outside," said Dr.
