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.

VW chair says component cost decrease keeps him confident of EV success

Volkswagen AG is in the middle of implementing a comprehensive electric vehicle strategy, one that we've been documenting for a long time. The Group stands ready to offer dozens of plug-in vehicles in the coming years if it feels there is sufficient demand and believes that selling a million EVs in Germany by 2020 is reasonable. That would be a solid number, but remember that VW sold over 5,923,000 passenger cars around the world last year, and the group as a whole sold over 9.7 million. At the company's annual Media Conference and Investor Conference in Berlin recently, the chairman of the board of VW AG - surrounded by some decidedly non-green examples of the VW Group's vehicles (some absurd new Bugatti, for example) - took some time to put the company's EV plans into focus. The upshot is that Dr. Martin Winterkorn is still guiding his electromobility ship into new waters, saying that "many more [plug-in] models will follow." Winterkorn said there are three main reasons he is confident in the ability of VW (and Audi and Porsche, at the very least) to push EV sales upward. Batteries are getting better, he said, and if the ranges can be extended, then customers are happy. But the real secret lies in reducing component costs. He said (as translated): It is important to look at the cost of the components: the battery technology, the electric motor and the electric components. Whenever you go into volume production, you of course have economies of scale. In two to three years' time, if we are able to achieve the goals we are setting for ourselves with cost and reach sufficient volume, I do believe that we can achieve two to three percent [market share] within VW Group. So, hitting a million EVs by 2020 is reachable. With the e-Golf and the e-Up off to excellent sales starts, we're willing to be confident as well.
