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.

VW looking to MAN up, ditch Mercedes van deal

Unlike the US, the commercial truck market throughout the rest of the world is chocked full of competitors from many different automakers. Since 2006, Volkswagen has had a fullsize van called the Crafter that was a result of a partnership with Daimler AG and based on the Mercedes-Benz Sprinter. This partnership is supposed to last through 2016, but Reuters is reporting that VW might be looking to end its relationship with Daimler and create its own van in cooperation with German truck and bus maker MAN.
The article says that VW AG has more than a 75-percent stake in MAN, which would essentially be keeping the new commercial vehicle in-house. Even if VW bolts, Daimler still has a deal worked out in the commercial truck industry between its subsidiary Mitsubishi Fuso and Renault-Nissan to supply the other with different trucks.

First official shot of Mercedes S-Class Coupe leaks out

With the official debut for the Mercedes-Benz S-Class Coupe expected tomorrow, it shouldn't be a surprise that some clicky fingers have already managed to uncover an official image of the car before the unveiling. Outside of this sole image, though, there's precious little detail on the new car.
First posted by Autofilou and then picked up by WorldCarFans, the production S-Class Coupe isn't far off from the concept car we saw a few months back in Frankfurt. Like the concept, the leggy production model appears related, albeit distantly, to the S-Class Sedan. The hood and front fascia are longer and lower, befitting of a two-door, while the character lines in the profile are more pronounced. Obviously, the beltline and slim, B-pillarless greenhouse are coupe-only items. We can't see any details on the back of the car, although it does appear that the long hood has a correspondingly short rear deck.
We'll have all the details on the official replacement for the CL-Class when it makes its full debut tomorrow. Until then, what do you think of this lone image? Does it appear that Mercedes has got it right? In terms of design, where would you rank this with the departing CL-Class? Have your say in Comments.
