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.

2013 Volkswagen Beetle Turbo Convertible

Less Flower, More Power
Pardon our political incorrectness for a moment, but the Volkswagen New Beetle was, undeniably, a "chick car." There was almost nothing that the New Beetle offered to enthusiasts (of either gender), and by the end of its run, VW had even stripped all of the exciting engines from the car's lineup. Looking to resurrect some of the excitement behind the Beetle, the third generation of the iconic car ditched the cuteness when the coupe debuted for 2012, and now the 2013 Volkswagen Beetle Convertible aims to show how much fun drivers can have without a top.
Celebrating almost six and a half decades of the Beetle convertible, Volkswagen is offering a trio of distinct special editions that celebrate three of the car's most popular decades (the '50s, '60s and '70s), but as one of the unofficial cars of the 1960s, it would almost be a crime not to test this version, right? Besides, this is also the only special edition to get the turbocharged engine. While our first drive of the 2013 Beetle Convertible was in the fuel-miser TDI variation, our two-week romp in the 2013 Beetle Convertible '60s Edition came just as peak convertible weather was kicking off down in Florida.
