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, Fiat, Mercedes could be CNG winners in Europe

Fiat ads in the US try to play up the exotic, sexy side of Italian culture. On the home front in Italy, however, passenger-vehicle sales are marked by something less edgy and quite a bit more practical: the growth of compressed-natural-gas (CNG) powered car sales. In fact, Italy is leading a group of European countries where CNG sales are on the upswing and may be benefiting automakers like VW, Fiat and Mercedes-Benz, according to Automotive News. VW started sales of its Golf TGI natural-gas vehicle this year – the company's fourth in Europe – while Mercedes-Benz added a natural-gas B-class model. Fiat accounts for about 50 percent of CNG vehicles sold on the continent. In all, Europe's CNG sales through September totaled about 67,000, up seven percent from a year earlier, Automotive News Europe says, citing research firm JATO Dynamics. And the number of CNG vehicles on Europe's roads could jump tenfold within the next decade. The draw is a combination of lower refueling prices and a CNG drivetrain that typically emits less CO2 than diesel vehicles. As for Italy, about five percent of new-vehicle sales are CNG. To put that into perspective, hybrids, battery-electric vehicles, plug-in hybrids and diesels combined to account for about 4.2 percent of US vehicle sales last year.

Mercedes-Benz F 015 Luxury in Motion has an absurd name, remarkable vision

We often hear about cars that don't look good in pictures. "You need to see it in person," people say. Well, the Mercedes-Benz F 015 Luxury in Motion, which the company brought to Detroit after debuting it at CES, is just such a vehicle. Besides having a very silly name and looking, according to one Autoblog editor, like a suppository, this is a genuinely striking piece of design when viewed in the metal. The shape is aerodynamic in the extreme, but still features subtle details and styling cues. Whether that be the small dorsal ridge on the roof, the simply huge wheels and the Cylon-like, wraparound taillights, despite a fairly uniform shape, there's still a lot to see on the F 015. That's doubly true in the cabin, which is typically luxurious, while also doubling as a rolling lounge withs eating for four. Accessible via barn doors that open up to 90 degrees, the F 015's cabin features fine woods and leathers, as well as seats that swivel around to face each other. Screens abound (there are six in total), and gesture-and-touch-based controls are the order of the day, producing what Mercedes calls a "digital arena." As an autonomous vehicle, MB doesn't offer a lot of technical information on propulsion or guidance systems, simply saying that the pod-like concept could accommodate an electric motor and fuel cell. Take a look at our gallery of live images Mercedes' sci-fi vision, and if there's an auto show coming to your neck of the woods, get out and see this strange and impressive car.
