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.

Mercedes testing C-Class plug-in hybrid modes in Germany

Testing appears to be underway for what would be the first Mercedes-Benz C-Class with a hybrid powertrain. We can see a pair of the prototypes undergoing testing in Germany, with one, a C-Class Wagon, still heavily clad in camouflage and featuring a more noticeable outlet on the passenger side of its rear bumper.
There's also a more production-looking sedan, which features a not-so-discreet flap over its rear-bumper outlet. It's difficult to speculate on power outputs for this fuel-sipping C-Class, although our spies seem to think that this car will feature some combination of a four-cylinder gas engine with an electric motor, although just which four is unclear (note, we wouldn't mind if MB fit its 2.0-liter turbo with some batteries and motors). Regardless, the four-pot/electric motor seems like a pretty reasonable combo, although it probably means that Mercedes won't be challenging the six-cylinder-powered system of the BMW ActiveHybrid3 any time soon.
When the plug-in C-Class arrives later this year as a 2015 model, it will likely offer a full range of driving modes, including both gas or electric, only, as well as a more traditional hybrid mode.

Does Alex Rodriguez' Mercedes dealership have a PR problem?

Alex Rodriguez, in case you haven't heard, is seemingly the new Most Hated Man In Baseball, ostensibly replacing commissioner Bud Selig (for now). Rodriguez was slammed with a 211-game suspension due to his role in the MLB's latest steroid scandal in which "A-Roid," as fans have taken to calling the former superstar, was cited with steroid use and attempts to hide his involvement by "engaging in a course of conduct intended to obstruct and frustrate" the investigation, according to the MLB's official report.
Why is this on a car site, then? Because Rodriguez' name is attached Alex Rodriguez Mercedes-Benz in League City, TX. An Ad Age report cites Mercedes-Benz USA in saying that A-Rod owns "about half'" of the dealership. Mercedes, for what it's worth, isn't going to any to any lengths to distance itself from its dealership or its controversial namesake, saying, "We never promoted the fact that A-Rod owned a dealership, so there's really nothing to 'distance' ourselves from. And since his activity is not illegal but rather prohibited by MLB, there's nothing actionable here."
With the scandal still a fresh piece of news and A-Rod's pending appeal, it's difficult to tell what sort of effect, if any, his name will have on the dealership's sales. Ad Age contacted the GM of Alex Rodriguez Mercedes-Benz to get the dealership's view, but no calls were returned. According to Mercedes, any name change is up to Rodriguez and his partner(s) at the dealership. Somehow, though, we think A-Rod has other things to worry about beyond his dealership's name.
