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 reveals updated Sharan minivan for Europe

Volkswagen's experiment with rebadging Chrysler minivans as the Routan may not have gone so well for the German automaker in North America, but overseas it offers vans of its own. Even aside from the fullsize Crafter and Transporter vans sold by Volkswagen Commercial Vehicles, the passenger car division offers its own minivans like the Touran and the Sharan. Now it's revealed an updated version of the latter. The VW Sharan was first introduced back in 1995 and entered its second generation in 2009, built in Portugal alongside the Seat Alhambra and offering seating for seven in its five-door form. The new model looks largely the same as the existing one, but benefits from new taillights and a revised interior. But most of the upgrades are found under the skin. There's an array of turbocharged and direct-injected engines that are now up to 15 percent more efficient than those found in the existing model, with two gasoline engines ranging in output from 148 horsepower to 217, and three diesels producing 113, 148 and 181 hp. Along with the updated powertrain options, the revised Sharan also gets a host of new safety and convenience systems, including automatic post-collision braking, Front Assist with City Emergency Braking, Lane Assist, Adaptive Cruise Control, Park Assist and Blind Spot Monitor. Inside, the infotainment system has been upgraded as well. The updated Sharan arrives hot on the heels of the new Caddy released earlier this month and just in time for the 2015 Geneva Motor Show. Wolfsburg, 18 February 2015 Show premiere of the Sharan in Geneva - Even more technical highlights for the popular Volkswagen MPV - New TSI and TDI engines* are up to 15 per cent more fuel efficient Volkswagen is presenting the technically updated Sharan at the Geneva International Motor Show. Numerous new convenience and assistance systems make the family-friendly MPV one of the most advanced models in its segment. A wide range of infotainment systems also guarantees full connectivity to many smartphones and tablets. At the same time, the fuel economy of the petrol and diesel engines* was improved by up to 15 per cent. The updated Sharan will arrive on the German market this summer; advance sales begin in April. Along with the standard Automatic Post-Collision Braking System, which automatically initiates braking after a collision if the driver is no longer able to intervene, numerous optional assistance systems are available in the updated Sharan as well.

Volkswagen says goodbye to Eos, Routan in 2015 updates

Usually automakers announce changes to their lineup individually on a vehicle-by-vehicle basis, but sometimes it all comes at once - especially when the changes are ones we either expected or might not otherwise notice. That's the path Volkswagen has gone with changes to its US lineup for 2015.
The biggest change is what we already knew: that the new Golf arrives for the 2015 model year, bringing with it the new GTI, Golf R, e-Golf and Golf SportWagen (to replace the previous Jetta wagon). But there are some new details as well.
For starters, Volkswagen has finally confirmed that both the Eos and the Routan - both long rumored to be on their way out - will be exiting this year. The Eos hardtop convertible, pictured above, will linger for one last year, its Sport trim replaced by a new Final Edition with 18-inch wheels, two-tone leather interior and enhanced equipment.
