2014 Volkswagen XL1 [w/video]

World's Most Efficient Car Impresses, Not Without Compromises
Among our many duties at the recent Geneva Motor Show, we were offered a pretty exclusive drive in the new Volkswagen XL1 hyper-efficient plug-in diesel hybrid. There is so much that is interesting about a car like this reaching production from a major automaker that it's tough to know where to begin.
First off, you should know that - at least for this generation - there is absolutely no chance in Albuquerque that this "1-liter vehicle" (i.e. a vehicle that can burn just one liter of fuel to travel 100 kilometers, or 62.1 miles) will ever make it into the hands of North American customers. We, too, were having trouble imagining an XL1 in typical American traffic, surrounded by comparatively massive pickups and SUVs. The driving experience had us recalling a couple of weeks in 1999 when we drove the then-revolutionary Honda Insight hybrid on US roads. We keenly remember the feeling of being very small and vulnerable, even as we felt proudly green in our 61-mpg Tochigi pod. Thing is, the Volkswagen is smaller still, and nearly as light despite its more complex drivetrain and safety features.

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 lays off 500 Chattanooga workers

The redesigned Volkswagen Passat has been a decent seller since its debut in 2011, but sales have apparently dropped off enough that the automaker is trimming some of the employees from its Chattanooga, TN assembly plant. According to Automotive News, Volkswagen will be cutting shifts and laying off 500 contracted workers in response to slowing sales.
Currently, the plant has three teams running 10-hour shifts Monday through Saturday, but starting May 13, this will be reduced down to two teams running 10-hour shifts Monday through Thursday. This will be done to reduce dealer inventory (the article says that VW dealers, on average, have a 97-day supply of Passats) and production capacity (currently running at an annual pace of 170,000 units, which is more than the 150,000 annual units the plant was planned to produce).
This, of course, isn't saying that the Passat has been a failure since VW added 200 full-time employees to the plant in February 2012 to keep up with increased demand. The AN article says that automakers frequently overstaff plants during the launch of a new product - or in this case, a new product and a new plant - but eventually reduce the workers as things run smoother and more efficiently.
