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.

Next-gen Volkswagen Golf R spied while running the 'Ring

The launch of a new Volkswagen Golf is never a small thing, and things are already looking up for the subcompact hatchback after it was named 2013 World Car of the Year. While we've already seen the base and GTI versions of the next-generation Golf, now we're getting our first look at the sportier Golf R.
Although this prototype wears GTI lettering on the front fenders, it's more than just the roll cage and Sparco racing seat hinting that this is something a little more serious. Unlike the Golf and GTI, this car shows that the Golf R will continue to flaunt massive air intakes on each side of the fascia, and the rear of the car (though it's hard to see) has quadruple exhaust outlets. We still don't have an official word on power, but rumors indicate that the next Golf R could be pushing close to 300 horsepower, making it the most powerful production Golf ever. As much fun as we had during our first drive of the Golf R Cabriolet in the cold, snowy French Riviera last month, more power is a warming idea.

VW agrees to halt next-gen rally car development to help others stay in WRC

Volkswagen has petitioned the FIA to hold on to the current specifications for cars in the World Rally Championship, according to Autosport.com. The move is evidently an effort to keep as many competitors in the sport as possible, despite the fact that using the current spec racers may actually hurt Volkswagen's chances at winning. The three factory teams currently competing in the WRC are at the end of a three-year homologation cycle at the end of 2013, and new cars are expected to bow next year. But developing new racers could cost as much as $4.7 million.
That price tag would put M-Sport (which fields Ford racers) out of the WRC game for 2014 and would put Citroën participation in question as well. VW has already begun work on the next iteration of its Polo R WRC, and the hatch has nabbed four wins in six rounds this season. Now it appears that car won't bow until at least 2015. The FIA has officially agreed to freeze homologation of new WRC cars until the end of next season.
