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.

Skoda racing Up! to Worthersee with Citigo Rally concept

If you thought the Volkswagen Group was about to wind down the endless stream of concept cars based on the new Up! city car, think again. Because not only is the Volkswagen brand itself keeping the train a-moving, so are its sister brands.
Skoda has its own version of the Up called the Citigo. But what racing fans know the Czech subsidiary for best is its rally program that has become a dominant force in the Intercontinental Rally Challenge and the basis for VW's own foray into the World Rally Championship. Now Skoda is bringing the two together with an exciting concept car previewed by the rendering above and confirmed in the press release below.
Following in the footsteps of the tantalizing Fabia roadster unveiled last year, the Citigo Rally concept is to be the centerpiece of the Skoda display at the Volkswagen Group's annual hot-hatch gathering at Lake Wörthersee in Austria. Details are scarce, but the show car will feature rally-inspired bodywork complete with 18-inch white alloys packed into aggressively flared wheel arches, a substantial rear wing and vents aplenty.

Volkswagen looking to acquire Proton, Lotus?

Let's say you're an automaker bent on world domination looking to grow your sales. That's going to have you looking at Asian markets, because that's where some of the biggest growth has been, and that's exactly what Volkswagen is doing as it considers making another run at Malaysia's Proton.
Reuters reports that Volkswagen is interested in at least a partial stake, if not a controlling interest in Lotus-parent Proton as a way to continue a production presence in the region without having to build its own factory.
Volkswagen already builds the Passat in a DRB-HICOM facility in Pekan, Malaysia, and plans are in place to build the Jetta and Polo there, as well. With both southeast Asia and its relationship with Proton figuring so importantly in Volkswagen's plans for expansion, buying into Proton can help ensure stability. Volkswagen is being tight-lipped about the whole idea, but CEO Martin Winterkorn did recently say, "it's our clear goal to continue the successful (expansion) course of past years with great dynamics and stability," which sounds an awful lot like deals are on the table to smooth the path to further growth.
