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.

Skoda unveils Volkswagen Up!-based Citigo

This is the all-new Skoda Citigo, and if you're thinking that it looks rather familiar, that's because its Volkswagen-badged kin recently debuted at the 2011 Frankfurt Motor Show. That's right, the long-rumored Skoda version of Volkswagen's new Up! city car has finally arrived.
Buyers will have a choice of two 1.0-liter three-cylinder engines - one with 59 horsepower, the other with a 74 hp and a blistering 106 mph top speed - both mated to a five-speed manual transmission. Powerful they are not, but these three-bangers should prove to be extremely efficient, with Skoda quoting fuel economy numbers of 62.8 and 60.1 miles per gallon, respectively (on the European cycle).
Being a Skoda, the Citigo will go on sale in its home market of the Czech Republic this fall, with the rest of Europe getting the car next summer. Follow the jump for Skoda's official release.
