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.

AMG-powered Aston Martins still years away

After flirting for several years, Mercedes-Benz and Aston Martin have finally tied the knot. Just don't expect to see any offspring to result from the union for at least three or four years.
This according to Auto Express, which spoke with Daimler chief Dr. Dieter Zetsche at the Frankfurt Motor Show last week. AE reports that a new range of AMG-developed turbocharged V8s, transmissions and electrical components will make their way into the successors to the current V8 Vantage and DB9, but that these models are still a few years off.
Purists might balk at the thought of a Mercedes-powered Aston holding true to the brand's heritage. But while David Brown (for whom the DB range is named) may have steered clear of shoehorning in Detroit muscle into his cars, the entirety of the company's current range is powered by engines borrowing technology from Ford, and that arrangement seems to have worked well for Aston until now. And if you're still skeptical, look no further than Pagani and its AMG-sourced engines and you should have all the proof you need that the new relationship between Daimler and Aston could be a success.

World Car Of The Year down to its final four

Judges for the World Car of the Year Award have narrowed down the finalists to just four vehicles. Out of a total of 42 entries, only the Mercedes-Benz A-Class, Porsche Boxster/Cayman, Scion FR-S/Subaru BRZ/Toyota GT-86 and Volkswagen Golf remain standing. For Volkswagen, this marks the second consecutive year the company has had an entry among the finalists, and the fourth time since 2009. In order to qualify, a vehicle must be on sale on two continents during the span of time between January 1, 2013 and May 30, 2013. A panel of 66 journalists from 23 countries then vote on the finalists.
Three vehicles have made the cut for the last round of voting on the 2013 World Performance Car as well, with the Cayman/Boxster and FR-S/BRZ/GT-86 running against the Ferrari F12 Berlinetta. Meanwhile, the Renault Zoe, Tesla Model S and Volvo V60 Plug-In Hybrid are duking it out for the World Green Car Award. Finally, the World Car Design of the Year Award is up for grabs between the Aston Martin Vanquish, Jaguar F-Type, and the Mazda6. Check out the full press release below. Overall winners will be presented at the 2013 New York Auto Show.
