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 tipped to launch turbocharged Up! with 100 hp

Overseas customers enticed by the compact dimensions of the Volkswagen Up! but turned off by its diminutive 1.0-liter three-cylinder engine may be encouraged by reports that the German automaker is planning a more potent turbo version. Previewed by the GT Up! concept showcased at the 2011 Frankfurt Motor Show (pictured above), the more performance-oriented model is expected to pack the turbo three from the larger Polo, where it produces 100 horsepower channeled through a five-speed manual transmission. That may not seem like much, but it would put the existing 59- and 74-horsepower versions of the German city car to shame. That might not give it enough punch to keep pace with the upcoming Smart Fortwo Brabus (and its Renaultsport Twingo counterpart), tipped to pack as much as 130 hp, but it could stand to out-perform the existing 89-hp turbo models of both. Given that the reports are emanating from Brazil, however, it is possible that the Up! Turbo (or whatever it's ultimately called) would be limited to the South American market, if it's built at all. One thing's for sure, though: it's not likely to make it to North American showrooms anytime soon.

2013 Volkswagen Golf R Cabriolet

The Golf VI's Last Hurrah Is Pure Niche
This was in the heart of the ultra-chic Côte d'Azur during winter. The car to be tested was the not-for-North America 2013 Volkswagen Golf R Cabriolet. Prevailing weather conditions here this time of year are bizarrely pleasant, as though a dome of Swarovski crystal has been placed over the entire region to protect it from any real winter spoiling things. And the zippy Golf R Cabriolet is a sports car designed precisely for this area's preciously narrow winding streets, as well as for the lofty budgets of its property owners.
So then why was it snowing like we were in northern Michigan? The weather front hit from the north like a swift kick to the Jordaches. The roof was open on this Candy White Golf R Cabrio and I, as is my wont, was determined through thick or thin to keep it retracted. It had been raining and sometimes sleeting like the End of Days, but I kept the lid cracked because the 261-horsepower cabrio - the most powerful convertible ever built by Volkswagen - was snipping along nicely as the bad weather blew over my head and wetted only the rear headrests.
