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.

Volkswagen CEO Martin Winterkorn resigns amid diesel scandal

Volkswagen CEO Martin Winterkorn is stepping down amid charges the company manipulated its diesel-powered cars to meet emissions regulations around the world, the automaker announced Wednesday. No successor was immediately announced, though recommendations will be made at VW's board meeting Friday. Winterkorn, 68, has led VW since 2007 and oversaw the German automaker's staggering growth around the world. His departure comes less than a week after the EPA alleged the company has been cheating on diesel emissions testing for years, and that its cars might emit 40 times more pollution than legally allowed. The EPA says about 482,000 vehicles are affected in the United States, and VW estimates at least 11 million vehicles globally might have the software that allows the vehicles to cheat emissions regulations. "As CEO I accept responsibility for the irregularities that have been found in diesel engines and have therefore requested the Supervisory Board to agree on terminating my function as CEO of the Volkswagen Group," Winterkorn said in a statement. "I am doing this in the interests of the company even though I am not aware of any wrongdoing on my part. "Volkswagen needs a fresh start – also in terms of personnel. I am clearing the way for this fresh start with my resignation." Winterkorn stepped down after an executive committee meeting of the VW Supervisory Board Wednesday. The committee agreed Winterkorn had no knowledge of wrongdoing. "The executive committee has tremendous respect for his willingness to nevertheless assume responsibility and, in so doing, to send a strong signal both internally and externally," VW said in a statement. Volkswagen is conducting an internal review and expects more "personnel consequences" in the coming days. It also will voluntarily submit a complaint to the state prosecutor's office in Brunswick, Germany, and cooperate with the expected criminal investigation. Winterkorn's departure is the latest development in VW's burgeoning diesel emissions scandal. It came to light last week after the work of researchers at West Virginia University detailed the software manipulation designed to skirt EPA tests, and it has resounded as governments around the world examine Volkswagen's diesel vehicles. The company set aside $7.3 billion to deal with the fallout and has retained the law firm that defended BP during its oil spill.
