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.

Volkswagen Group previews its wares on eve of Geneva show

The Volkswagen Group is comprised of 11 brands producing 240 vehicles across 49 factories throughout the world. So the best way to show off the range of the VW family is to cram a few thousand journalists and VIPs into a massive makeshift stand to outline the Group's goals, what's in the pipeline and what you'll be able to buy later this year.
To that end, VW pulled out all the stops on the eve of the 2012 Geneva Motor Show, bringing along 10 vehicles from across the range. We'll be delving into the details of each over the next two days of show coverage, but before that happens, you can read all about what we saw tonight from the cheap seats after the break.

VW readying new VR6 with forced induction

Volkswagen built a stonking, narrow-angle V6 in the 1980s and 1990s that was found in three different generations of the Golf (their performance iterations, obviously), three generations of the Passat, the New Beetle, the Corrado and the Touareg, among other VWs, a spate of Audis, Seats, a Skoda, and even the Porsche Cayenne. It was a sad day when it was announced that it'd be put out to pasture.
Rejoice, though, fans of the venerable VR6, because Volkswagen has a new, modern variant in the works that, according to AutoWeek, features direct injection and can easily be fitted with forced induction. In fact, AW mentions Volkswagen insiders that claim this unit will spawn a production version of the twin-turbo V6 shown on the Design Vision GTI from this year's Wörthersee festival. That unit produced an epic 503 horsepower and 413 pound-feet of torque.
Don't expect a production unit with that level of power (although it would make a hardy RS4 powerplant), though. In reality, AutoWeek is suspecting anywhere from 340 to 450 horsepower from the new mill. When it arrives at an undisclosed date in the future, it'll likely be found in the Passat and Passat CC as well as the production version of the CrossBlue.
