Volkswagen names new chief designer for Bentley

The Volkswagen Group has named one of its own to head up the design department at its Bentley division. The role now falls to Stefan Sielaff, who has been with the group (off and on) since 1990. Sielaff is principally an interior designer, but has been tasked with setting up numerous overall design offices for Volkswagen and Audi over the years. In his new capacity he'll be reporting to the group's chief engineer Rolf Frech (and oddly not to Bentley chief Wolfgang Durheimer), but at the same time, Sielaff will retain his role as head of interior design for the entire VW group, reporting to its chief designer Walter de Silva. Sielaff replaces Luc Donckerwolke, who has headed up Bentley design since 2012 and is leaving the company. We'll be on the lookout to see where Donckerwolke lands next. Crewe/Wolfsburg, 04 June 2015 Stefan Sielaff to head design at the Bentley brand • Sielaff also responsible for Group Interior Design Strategy Stefan Sielaff (53), currently Head of the Volkswagen Design Center in Potsdam, will assume responsibility for design at the Bentley brand effective July 1, 2015 in addition to his present post as Head of Group Interior Design Strategy. As Director of Design at Bentley, Sielaff succeeds Luc Donckerwolke (49), who held this function since 2012. Stefan Sielaff joined the Volkswagen Group in 1990, beginning his career in the interior design department at Audi. From 1995 the design graduate was entrusted with setting up the Group's Design Center Europe in Spain. In 1997 he was placed in charge of the Design Studio in Munich and was appointed Head of Audi Interior Design in the same year. In 2003 Sielaff moved to DaimlerChrysler as Design Director of the Interior Competence Center, returning to the Volkswagen Group in 2006 to become Head of Audi Design before being appointed Head of the Volkswagen Design Center in Potsdam und Head of Group Interior Design Strategy in 2012. In his new function as Director of Design at Bentley, Sielaff reports to Rolf Frech, Board Member for Engineering. In his function as Head of Group Interior Design Strategy he continues to report to Walter de Silva, Head of Group Design. Luc Donckerwolke has decided to leave the company. De Silva said: "Luc Donckerwolke has played a key role in the design of various Group brands. We would like to thank him for his work."

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.

Volkswagen planning Up! hybrid model using XL1 powertrain

Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up! minicar (shown above).
A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. The hand-built XL1 will use a 47-horsepower, two-cylinder TDI engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 31 miles.
One of the core pillars of the XL1's design is its lightweight construction with a 1752-pound curb weight, which makes the Up! a perfect recipient for using this powertrain since it weighs just 300 pounds more. The report says that the Up! Hybrid is still in the developmental phase, so a production version isn't expected for at least another 18 months.
