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 Tiguan and Touareg take the R-Line

Volkswagen's Detroit Auto Show presence is big on utility this year, with the CrossBlue three-row concept vehicle occupying the lion's share of the limelight, both literally and figuratively. But that isn't stopping Volkswagen from lavishing attention on its already established crossover and sport utility vehicles with new R-Line derivatives. The Tiguan and its big brother Touareg are getting a host of look-faster items to increase their sporting appeal.
On the outside, the Tiguan R-Line receives handsome 19-inch alloys peering out from beneath fender extensions, premium lighting (bi-Xenon headlamps with LED daytime running lamps), along with matching side skirts and a liftgate spoiler. On the inside, sportier accommodations include aluminum trim and a flat-bottom steering wheel with paddle shifters. As with other R-Line models, there are no powertrain modifications to go with the more aggressive visuals (that being the province of R standalone performance models like the R32), though the suspension has been firmed up an unspecified amount. The Tiguan R-Line will be available in front- or all-wheel drive configuration.

2014 Volkswagen Golf GTD is our favorite oil-burning GTI

The 2014 Volkswagen Golf GTD has officially bowed at the 2013 Geneva Motor Show. Engineers managed to squeeze an additional 14 horsepower and 22 pound-feet of torque out of the familiar 2.0-liter turbodiesel four-cylinder engine, nudging total output to 184 hp and 280 lb-ft for 2014. The figures are good enough to earn the GTD the honor of being the most powerful diesel Golf in Volkswagen history. A start/stop system helps improve efficiency over the previous generation with the new model consuming 56 miles per gallon on the EU cycle. That's up from the 2013 model's 46 mpg. A six-speed manual transmission is standard equipment, though a six-speed dual-clutch gearbox is also available.
The GTD also offers buyers a few aesthetic tweaks to help separate the hatch from its less potent siblings. Those include a more aggressive front fascia, special badges and 17-inch alloy wheels. Expect to find the GTD in one of three exterior colors, including Tornado Red, Black and Pure White. Check out the quick press release below for more details.
