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.

Carlsson turns Mercedes-Benz SLK into 610-HP hill-climb clawer

Carlsson's race-tuned versions of the Mercedes-Benz SLK have been taking checkered flags for years, and we won't be surprised if its SLK 340 hill climber fares any different. Developed by multiple German and Swiss hill climb champion Reto Meisel, the carbon-bodied SLK 340 with lightweight brakes and a closed underbody weighs 1,716 pounds. Propelling that tiny bit of weight is a 3.4-liter V8 from Judd with 610 horsepower, and it rolls on 18-inch wheels shod in Avon tires.
It will debut at the Geneva Motor Show before beginning its racing campaigns in the summer. This one won't just tear up roads in Europe, though - Meisel says he plans on bringing it to the Pikes Peak International Hill Climb. The press release below has more details.

Europe getting special Mercedes-Benz CLA Edition 1

Last week when we saw the leaked ordering guide for the 2014 Mercedes-Benz CLA-Class, one particular image caught our eye showing the interior of the new sedan with a neon yellow stripe on the seats and yellow stitching throughout the cabin. As it turns out, this will be part of a limited-edition model called the Edition 1 about which Mercedes-Benz just released some information.
Usually, automakers wait until later in a vehicle's life to introduce special models like this, but the Edition 1 will be available right out of the gate for the first 12 months the CLA-Class is on sale. The 2014 CLA-Class Edition 1 includes the more aggressive Sport package adding AMG-style fascias and wheels, Bi-Xenon headlights and a lowered suspension; it will be offered only in five colors - unfortunately, Northern Lights Purple is not one of them. In addition to the bright yellow cabin accents, the Edition 1 will get sport seats wrapped in leather and microfiber, a sporty, flat-bottom steering wheel wrapped in Nappa leather and real aluminum trim on the instrument panel.
With no mention of the US, we're only left to imagine that this car will not be arriving on our shores, but customers in Europe will definitely be able to enjoy the mean styling and funky interior with prices ranging from 35,402 euros up to 43,940 euros.
