VW XL1 priced at $169,000 in UK, only 30 will be sold there

Volkswagen has announced the pricing of its XL1 diesel plug-in hybrid for the UK, according to Car magazine. The small, uber-efficient two-seater will start at GBP98,515, or roughly $168,930 at current exchange rates. Additionally, only 30 units of the XL1 will be sold throughout the UK, giving it a rareness appropriate for its lofty price. It's nice to finally be able to stop speculating about the XL1's price. Even as recently as the first XL1 delivery in Germany, we were still mostly in the dark concerning the cost of the slippery VW. But is the price worth it, especially considering that the much sportier BMW i8 can be had for just a bit more (GBP99,895, or $171,460, in the UK)? Car seems to think so, noting that the XL1 is an eco and technology pioneer, and saying that its cost of ownership is "merely the price of progress." Plus, that includes the bragging rights of owning the world's most fuel-efficient car. The XL1's two-cylinder turbo-diesel engine displaces just eight-tenths of a liter and produces 47 horsepower. The internal combustion engine operates alongside a 26-horsepower electric motor powered by a 5.5-kWh lithium-ion battery pack. Despite its 2.64-gallon fuel tank, the XL1 has a maximum driving range of over 700 miles thanks to a 261-mpg rating (based on the European cycle). Unfortunately, we won't be able to do any bladder-busting, nonstop Chicago to DC road trips any time soon, as VW has no plans to bring the XL1 to North America - not that one would relish the experience of dicing it up with America's massive trucks and SUVs. If you want to drive one, you'll have to go to Europe, and you'd better have a very large piggy bank you're prepared to break open.

VW invests in QuantumScape for potentially fireproof, long-range EV batteries

VW might be getting ready to push its plug-in technology in a big way thanks to an investment in the battery startup QuantumScape. Key point: the solid-state battery is said to be fireproof and will offer tremendous range advantages. Details are not abundant yet, but according to Bloomberg, VW of America bought a five-percent stake in QuantumScape (and has an option to raise its holding). The tech could "more than triple" the EV range of VW, Porsche and Audi plug-in vehicles as soon as the middle of 2015, according to unnamed sources that Bloomberg talked to. Former Stanford University researchers started QuantumScape in 2010. The bare-bones QuantumScape website (there's nothing there other than some contact information) doesn't offer many hints about what's happening at the company, but GigaOM's Katie Fehrenbacher notes that QuantumScape is licensing tech from the "All Electron Battery" project at Stanford a few years ago. It certainly sounds amazing: [It's] a completely new class of electrical energy storage devices for electric vehicles that has the potential to provide ultra-high energy and power densities, while enabling extremely high cycle life. The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. ... If successful, this project will develop a completely new paradigm in energy storage for electrified vehicles that could revolutionize the electric vehicle industry.

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.
