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.

Maybach lost upwards of $500k on each vehicle sold

Daimler is shuttering Maybach in 2013 after seven years of production. In that time, the company's ultra-ultra-luxury arm managed to sell just 3,000 units, and CAR reports Daimler lost somewhere around $500,000 on each and every one of them.
Even with a ludicrous price tag of over $370,000 for an "entry" Maybach 57, the brand couldn't quite recoup the dizzying $1.33 billion Daimler poured into it since its (re)inception. Rumors ignited over a possible tie up with Aston Martin that would have resulted in a range of new and attractive models, but Daimler has instead decided to snuff out Maybach altogether.
We can hardly blame them.
