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.

Volkswagen New Midsize Coupe Concept is an aspirational Jetta

Meet the Volkswagen baby CC. Okay, that's not really it's name (VW calls it the New Midsize Coupe Concept), but this sleek, four-door coupe draws more than a little inspiration from the CC while riding on VW's MQB platform.
It's a looker, we think, and is an eye-pleasing departure from the bland styling of the current Jetta. The sleeker front end is complemented by a wider body overall (it's wider than a Passat), while the more sporting roofline and the sharp rear fascia gives the New Midsize Coupe a decidedly sporting character. LED head- and taillights add a bit more personality to this already stylish design.
Thanks to its 2.0-liter, turbocharged four-cylinder, it should get along rather sportingly, as well. The run to 62 miles per hour takes just 6.5 seconds thanks to the 217 horsepower on offer. A seven-speed dual-clutch automatic is also fitted, and contributes to an estimated 37 miles per gallon.

VW LogBox and Race App performance data logger for R models [w/video]

Now that it's got a 300-horsepower Golf R to brag about, Volkswagen wants you to be able to brag about it accurately with the LogBox and Race App performance data logging combo. Plug the LogBox into your VW's OBD II port and it sends data over BlueTooth to the Race App, measuring variables like acceleration, distance, G-force and engine performance. If you're on a circuit, it uses Google Maps to make a map of the track, and you can record live video in-app to match with the data. Volkswagen says the LogBox will be available for R models and "a range of further Volkswagen cars," so you'll want to hit up your dealer with questions before ordering. It's available from the VW accessories store for 299 euros ($365 US), but right now the free app is only available in German, in the German-language iTunes and Google Play store. We imagine that will be corrected shortly; in the meantime, the video can show you how it works.
