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 adding R-Line trim to Touareg, Tiguan for 2014

Volkswagen introduced its aggressive R-Line appearance package on the CC and Beetle last year, but later this year, this treatment will also be applied to VW's crossovers, the Tiguan and Touareg. Both sporty-looking utility vehicles will be unveiled next week at the Detroit Auto Show.
The 2014 Tiguan R-Line comes standard with bi-xenon headlights and LED daytime running lights, and the package adds 19-inch wheels, grey fender extensions, body-color side skirts and a liftgate spoiler. Inside, the R-Line adds a flat-bottom sport steering wheel with paddle shifters, a black headliner and numerous metallic trim accents such as the stainless scuff plates, the aluminum pedals and metallic finish on the instrument and door panels. The Tiguan R-Line will be offered in front- and all-wheel drive configurations.
As for the 2014 Touareg R-Line (shown above), this model gets an ever more distinctive look with an aggressive front fascia, 20-inch wheels and dual oval-shaped exhaust outlets in addition to the painted side skirts and LED taillights. Similar metallic interior trim pieces found inside the Tiguan R-Line will also make their way into the Touareg as well as gloss black accents on the instrument panel and center stack.

CEO says Volkswagen's buying spree is over

After adding Italian motorcycle icon Ducati to its stable and spending $5.6 billion on the rest of Porsche, Volkswagen CEO Martin Winterkorn says he's done shopping for a while.
"We have enough to do at the moment in taking our twelve brands to where we want to be," Winterkorn tells German newspaper Handelsblatt.
