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.

Mercedes celebrates with World Championship edition SL63

Mercedes has plenty to be celebrating at the moment, having just won the Formula One World Championship in spectacular style – taking the constructors' title by a huge margin and the top two slots in the drivers' standings as well. It almost goes without saying that the German outfit would celebrate with a special edition, and that's just what we're looking at here. Presented at a special celebratory Stars & Cars event in Stuttgart in front of 50,000 jubilant fans, the Mercedes-Benz SL63 AMG World Championship 2014 Collector's Edition is based on Benz's twin-turbo V8-powered roadster but with some choice upgrades. Two versions will be offered: one in black with gold accents (displayed with the Silverstone circuit layout), the other in white with silver accents (and the Hockenheim map). One was designed by Lewis Hamilton, the other by Nico Rosberg. We'll let you sort out which one was done by which, but either way there'll only be 19 examples, each dedicated to a different grand prix circuit in the championship which Mercedes positively dominated – winning all but three, scoring eleven one-two finishes and landing on the podium at each and every one.

Mercedes, Nissan and VW slammed by China's CCTV

Several automakers in China, including joint ventures with Nissan, Volkswagen and Mercedes-Benz, are in hot water because their dealers are allegedly overcharging customers for repairs. China Central Television, the country's state broadcaster, leveled the claims during its annual Consumer Day expose. CCTV runs these reports each year on March 15 and often takes aim at foreign companies operating within China. This year the focus fell on automakers, according to the Financial Times, and no domestic car companies were targeted. The network also accused dealers of overselling parts, and it took aim at Jaguar Land Rover specifically for problems surrounding transmission repairs, according to Reuters. The yearly stories are often criticized for focusing on outside businesses. "It panders to a certain type of nationalism as it tends to target foreign companies and rarely touches large state groups or monopolies," Qiao Mu, a journalism professor at Beijing Foreign Studies University, said to the Financial Times. Foreign automakers seem to face tighter scrutiny when doing business in China than their domestic counterparts, in general. The government there investigated several luxury brands, including Audi and BMW, last year for how they supplied spare parts and whether the components were overpriced. Some incurred fines, and Lexus decided to lower its prices. Volkswagen also experienced protests when owners felt the company wasn't handling a recall properly. The CCTV report also comes as many auto dealers in China are feeling a pinch due to high mandated sales targets from automakers. The situation was so dire in early 2015 several brands cut back sales targets and in some cases even paid the sellers to offset poor profits.
