VW joins Daimler's protest of new A/C refrigerant as EU deadline for compliance passes

The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of testing by governments, outside safety agencies and automakers to approve the chemical for use in cars. It passed the protocols necessary for the European Union to declare that new and significantly revised cars from 2013 onward needed to use R-1234yf, and mandated that every car as of 2017 must use it.
Enter Daimler AG. The automaker created a head-on collision test with a B-Class at their Sindelfingen test track that would lead to the pressurized refrigerant being sprayed on the engine. The result in 20 out of 20 test was that the refrigerant burst into flames as soon as it hit the hot engine, while Daimler says that R-134a does not catch fire in the same test. Another unexpected result of the R-1234yf test was the release of hydrogen flouride, a chemical far more deadly to humans than hydrogen cyanide, emitted in such amounts that it that turned the windshield white as it began to eat into the glass.
Said a Daimler engineer in a Reuters piece, "It was scarcely believable. The most complicated lab tests conducted using the most sensitive measuring instruments around found nothing and all we do is drive a car around a couple of times, open a tiny hole in the refrigerant line and the next thing you know the car is on fire." So Daimler said it wouldn't use the refrigerant, and it recalled the cars it had already shipped with R-1234yf.

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.
