VW offers to buy back new diesels if bans introduced

By Maria Sheahan FRANKFURT, Germany — Volkswagen will buy back new diesel cars if German cities ban them, it said on Thursday, seeking to reassure potential buyers and stem a plunge in sales of diesel vehicles. Europe's biggest automaker also said it would extend incentives for buyers of new diesel cars. The moves come after a German court ruled last month that cities in the country could ban the most polluting diesel vehicles from their streets. Many German cities exceed European Union limits on atmospheric nitrogen oxide, known to cause respiratory diseases. Fears of bans have led to a plunge in demand for diesel vehicles, which are also key to carmakers' attempts to meet new EU rules on carbon dioxide (CO2) emissions. While diesel cars are heavily criticized for emitting nitrogen oxide, they spew out less CO2 than gasoline equivalents. Diesel car sales plunged 19 percent in Germany last month. At its core VW brand, Volkswagen said its buyback offer applied to new diesels bought between April 1 and the end of 2018 and would kick in if the city in which the buyer lived or worked banned diesels within three years of the purchase. It said its dealerships would buy back diesel vehicles affected by bans at their current value if their owners at the same time bought a new vehicle that was not affected by cities' driving restrictions. At Czech brand Skoda, the guarantee applies to cars bought between April 1 and the end of June, but will cover bans introduced within four years of the purchase date. At premium brand Audi, the offer only covers leased vehicles. Volkswagen also said it was extending to the end of June incentives for customers trading in older diesels for new ones. Fellow German carmaker BMW said earlier this month it would offer to take back leased vehicles if diesels were banned within 100 kilometers (62 miles) of the operator's home or place of work. There has been a global backlash against diesel-engine cars since Volkswagen admitted in 2015 to cheating U.S. exhaust tests. But Germany's government is seeking to avoid widespread bans on heavily polluting diesel vehicles, which companies say could cut the resale value of up to 15 million vehicles in Europe's biggest car market. In Germany, where motorists expect to drive powerful cars on motorways with no speed limits, any restrictions will be unpopular.

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 e-Co-Motion concept poised for delivery to Geneva

With Nissan getting ready to launch the e-NV200, it appears Volkswagen is looking to go after the same zero-emission commercial vehicle market with the all-electric 2013 e-Co-Motion Concept. Debuting next week at the Geneva Motor Show, the e-Co-Motion Concept might be small in size, but VW says it has cargo and payload capacities that should be perfect for small businesses.
Measuring 179 inches long, 75 inches wide and 77 inches tall, the e-Co-Motion Concept has about the same footprint as the current Golf, and it has a cargo capacity of 162 cubic feet and a maximum payload of more than 1,700 pounds. There isn't too much information on the e-Co-Motion just yet - such as what electric components and platform are used - but the press release posted below states while the concept is shown as a cargo van, future body styles could include a passenger wagon or a refrigerated box van.
