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.

2014 Mercedes-Benz CLA order guide leaked

The dealer order guide for the 2014 Mercedes-Benz CLA has made its way online courtesy of the crew at CLAForums.com, and not only does it shed light on the ways buyers will be able to configure the entry-level sedan, it talks specific option pricing. Shoppers will be able to select between the CLA250 and CLA250 4Matic, and the option sheet should offer a number of packages to suit buyer tastes, including a sport package with tweaked fascias and unique wheels. Bi-xenon headlamps and 18-inch alloys may also be had as well as a panoramic sunroof and a collision avoidance system. The CLA will be available with a number of active safety systems on board, including lane departure warning, adaptive cruise control, park assist and blind spot assist, to name a few.
The new sedan comes in 10 colors, including a very dashing purple Mecedes-Benz calls Northern Lights Violet, and there are a total of four interior trim finishes. The automaker hasn't released final pricing of all models just as of yet - we do know from Mercedes' Kate Upton Super Bowl ad that the car will start at $29,900 - but you can check out individual option and package pricing in the gallery.

Mercedes-Benz S63 AMG officially teased in mini video

The followup to the Mercedes-Benz S550, the S63 AMG, will sport a biturbocharged V8 that will likely turn out around 550 horsepower. The new engine is probably the 5.5-liter, biturbocharged V-8 that's been popping up in everything from the ML63 to the E63 AMG. The front fascia is more aggressive, which shouldn't come as a surprise, while a meaty exhaust setup can be found out back.
We managed to pick all that up from a short, 17-second video posted by MB. The original video that unveiled the S63 AMG has since been pulled down, making this YouTube clip the best look we now have at the new super sedan, at least until the Germans give up the goods for real.
Be sure to check out the video below, along with our original posting on the S63 AMG.
