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.

Russia gives its Olympic medalists new Mercedes

Russian medalists at the recently concluded Sochi Winter Olympics are being rewarded quite handsomely for their service to the Motherland. In addition to the $120,000 being handed out for each gold medal, the $76,000 being awarded for slivers and $52,000 given to bronze winners, now word has come out that each of Russia's medalists will be gifted a new Mercedes-Benz.
As with the prize amounts, the type of Mercedes offered was based on what sort of medal was won. Gold medalists got a new GL-Class, silver medalists were given an ML and bronze medalists were treated to a GLK. As prices for Mercedes are higher in Russia, the cheapest model, the GLK, was the equivalent of $59,500, according to The Moscow Times. The cars were handed out by Russian Prime Minister Dmitry Medvedev, pictured above with figure skating medalist Julia Lipnitskaia.
"I was a bit shocked at the car I was given," Anton Shipulin, a member of the gold-medal biathlon relay team, told RIA-Novosti. "Of course I knew what kind of model it would be, but I didn't totally believe it." For athletes not old enough to drive, like 15-year-old Lipnitskaia, their Mercedes will come complete with a driver.
