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.

VW chair says component cost decrease keeps him confident of EV success

Volkswagen AG is in the middle of implementing a comprehensive electric vehicle strategy, one that we've been documenting for a long time. The Group stands ready to offer dozens of plug-in vehicles in the coming years if it feels there is sufficient demand and believes that selling a million EVs in Germany by 2020 is reasonable. That would be a solid number, but remember that VW sold over 5,923,000 passenger cars around the world last year, and the group as a whole sold over 9.7 million. At the company's annual Media Conference and Investor Conference in Berlin recently, the chairman of the board of VW AG - surrounded by some decidedly non-green examples of the VW Group's vehicles (some absurd new Bugatti, for example) - took some time to put the company's EV plans into focus. The upshot is that Dr. Martin Winterkorn is still guiding his electromobility ship into new waters, saying that "many more [plug-in] models will follow." Winterkorn said there are three main reasons he is confident in the ability of VW (and Audi and Porsche, at the very least) to push EV sales upward. Batteries are getting better, he said, and if the ranges can be extended, then customers are happy. But the real secret lies in reducing component costs. He said (as translated): It is important to look at the cost of the components: the battery technology, the electric motor and the electric components. Whenever you go into volume production, you of course have economies of scale. In two to three years' time, if we are able to achieve the goals we are setting for ourselves with cost and reach sufficient volume, I do believe that we can achieve two to three percent [market share] within VW Group. So, hitting a million EVs by 2020 is reachable. With the e-Golf and the e-Up off to excellent sales starts, we're willing to be confident as well.

2015 Volkswagen Passat Alltrack ready for any road, except in the US

If Volkswagen built a Subaru Outback-fighter for US buyers, the Passat Alltrack would be it, and the new generation of VW's off-roading wagon debuted this week at the Geneva Motor Show. The Passat Alltrack – which is not sold in the United States – takes the car-like demeanor of the Passat and punches it up into a go-anywhere crossover. It has permanent 4Motion all-wheel drive, raised ride height and an electronic differential lock. The body is fitted with modified bumpers with underbody guards, reinforced wheelarches and side moldings with extended sills. There are roof rails on top, and it rolls on standard 17-inch wheels with 18s and 19s optional. The Passat Alltrack offers five direct-injected engines, with the lineup comprised of two turbocharged gasoline mills and three turbo diesels. Volkswagen loaded the vehicle with a wide range of infotainment and safety features, including choices of five radio and navigation units. It also has fully digital instruments, heads-up display and a rear-seat entertainment system setup for laptops. There is also lane-changing assist, rear-traffic alert and trailer-assist features. As spokesman confirmed to Autoblog there are no plans to bring the Passat Alltrack to the US market. The new Passat Alltrack • World premiere at the Geneva International Motor Show • All-wheel drive all-rounder* combines exceptional off-road properties with excellent travel comfort The latest generation of the Passat Alltrack* is celebrating its debut at this year's Geneva International Motor Show. Based on the new Passat Estate, the new Passat Alltrack impresses with an independent off-road look, 4MOTION permanent all-wheel drive and highly advanced technologies. The updated version confidently handles rough terrain, on the one hand, while simultaneously providing excellent cruising comfort – thanks to the driving profile selector and DCC adaptive chassis control. The Passat Alltrack is an independent model within the model series. This can be seen in exterior features such as the modified bumpers (with underbody guard in stainless-steel look), rugged wheel arch and side sill moulding covers in "Anthracite" and sill extensions. Its 27.5 mm higher ground clearance also makes it ready for any driving situation. Anodised silver roof rails, "Alltrack" badges on the radiator grille and tailgate, and custom 17-inch alloy wheels (18- and 19-inch wheel options available) upgrade this Estate even more.
