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 Golf R 400 Concept is a 201-mph hot hatch

This, friends, is what happens when you shoehorn 395 horsepower into a Golf. You get a three-door hatch that will happily scurry to 62 miles per hour in 3.9 seconds and on to a top speed of 201 mph. Oh yes, we like you, Golf R 400 Concept.
As we explained in our original post, the R 400 is the long-awaited successor to bonkers Golf creations like the GTI W12 from 2007 and, more recently, the Design Vision GTI. It's powered by the same 2.0-liter, turbocharged four-cylinder found in a number of Volkswagen (and Audi, SEAT and Skoda) products, although it's been heavily massaged to pump out 332 pound-feet of torque along side its amplified horsepower.
Naturally, it's been lowered and now rides on 19-inch wheels. Outside of those changes, though, mums the word on suspension and chassis enhancements. While this is a bummer, the striking looks of the Golf R 400 more than make up for it.

2014 Volkswagen Beetle Convertible gets the R-Line treatment

Volkswagen just launched the topless Beetle Convertible at the Los Angeles Auto Show in November, but we're already seeing the next step forward in the topless Bug range with this, the R-Line. We'll admit, this treatment falls under the "all show and no go" category, but it's still a pretty potent little cutie.
The R-Line starts with a standard Beetle Turbo Convertible but adds unique 19-inch aluminum wheels on lower-profile tires, LED daytime running lamps and Xenon headlamps. Naturally, there are R-Line badges aplenty both on the interior and exterior, and we must say, the whole package looks pretty darn snazzy.
Pricing has yet to be announced, but when it goes on sale later this year, the hotter convertible will join Volkswagen's growing R-Line portfolio that now includes the CC, Beetle hatch, Tiguan and Touareg.
