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.

Happy 60th to the VW Karmann Ghia

Volkswagen's product portfolio may be as extensive these days as any other carmaker in the business. But if you still think of the original Beetle as synonymous with the brand, that's probably because a) you're old and b) the Beetle was the company's only product until the mid-50s.
Sixty years ago Wilhelm Karmann (founder of the eponymous coachbuilder) was in Paris for the auto salon and met up with Luigi Segre and his team from Carrozzeria Ghia who showed him what was essentially a "Beetle in a sports coat." A month later they showed it to Volkswagen chief Heinrich Nordhoff who, setting aside his conservative tastes, approved it for production. And so the Volkswagen Karmann Ghia was born, giving the German marque a second product line. It still used Beetle mechanicals and was built at the same Karmann factory in Onsabrück that was already assembling the Beetle Cabriolet.
It took another couple of years to put the design into production, but from 1955 to 1974, Volkswagen and Karmann built 362,601 coupes and 80,881 of the subsequent convertible that arrived in 1957. Today the Onsabrück factory is part of the VW Group, handling production of the Golf Cabriolet, XL1 and Porsche Boxster and Cayman, and with that original Karmann Ghia prototype as part of its factory collection.
