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 teams with Pebble for smartwatch tech

Most automakers have realized by now that a good infotainment system is a must-have feature for many buyers, and have, as a result, invested increasing amounts of time and money developing these technologies. But some automakers are going above and beyond in-car entertainment and navigation technology by focusing on wearable technology as well.
Nissan has emerged as one such company, developing its own alternative to Google Glass and performance-oriented smartwatch. But Mercedes-Benz is also putting itself at the forefront of wearable tech - not by developing competing products to those designed by dedicated tech companies, but by working with them. The German automaker, as we recently reported, is developing its own app for Google Glass, and is now doing the same with smartwatches as well.
Set to be unveiled at the upcoming Consumer Electronics Show in Las Vegas, Mercedes has collaborated with Pebble Technologies to develop the Digital DriveStyle app. The system will display tell its wearer where the car is, whether the doors are locked and if it needs fuel. Inside the car it'll alert the driver to potential hazards coming up on the road, while making functions like re-routing the nav system, controlling the audio system or activating Siri that much easier.

2014 Mercedes-Benz E-Class lineup shows its freshened face

Mercedes-Benz showed us its redesigned 2014 E-Class more than a month ago, but the Detroit Auto Show finally gave us a chance to see the full family of mid-size luxury cars and wagons in the flesh. Dieter Zetsche introduced the cars, including sedan, coupe, convertible and station wagon, on stage showing the stylish new design direction.
The wagon and sedan versions (shown as the E400 Hybrid above) will go on sale this spring, while the coupe and cabriolet will hit showrooms over the summer. Check our new gallery of live shots for the entire 2014 E-Class lineup, as well as the previously released press release below.
