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.

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.

The 911 Of Hot Hatches Takes The Compact Game To New Levels
North American car buyers get a bit of a slap in the face when it comes to delivery schedules for new the Volkswagen Golf and pumped-up GTI models. We'll just repeat the old chestnut: It's worth the wait... even though it still stinks. This time around, Western Europe is taking deliveries of the new Golf as we speak, and GTI deliveries start between May and July. North America doesn't get the Mk7 Golf or GTI until about July of 2014.
So we approached our first drive of the new GTI with this chip on our shoulder: "You're making us wait? Well, then at least give us the exact car we'll be able to buy. No compromises, mein freund." And so it was that we extracted nearly all of our drive impressions from behind the wheel of what, for the United States, will technically be a model year 2015 two-door Volkswagen Golf GTI Performance with the standard six-speed manual.
