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 expanding in Chattanooga, hiring workers ahead of SUV production

Hey, look! We're writing about Volkswagen's Chattanooga, TN factory and the focus isn't on yet another unionization effort. That's because the big news at the still-new factory is VW's plan to expand and increase its workforce in preparation for the arrival of the German brand's long-awaited midsize crossover. The expansion, which will add over half a million square feet of factory space, overhaul the assembly, body and paint shop and add 2,000 employees to the factory's ranks, officially kicked off last month. "This is a very exciting time in the history of Volkswagen Chattanooga," president and CEO of operations at the plant, Christian Koch, said in a statement. "A lot of hard work is going into adding this second vehicle line to the plant, but it is crucial to our efforts to move forward in America." "Not only will Volkswagen's expansion create thousands of new jobs, it will strengthen their roots in our city," Chattanooga's Mayor, Andy Berke, said in a statement. "From the construction at the plant to the development of a visitors center, there is no doubt that Volkswagen is invested in Chattanooga." VW Chattanooga has been a constant in the headlines over the past few years as pro-union and pro-business interests have battled over the souls representation rights of its roughly 1,500 workers. Just over a year ago, the UAW was defeated in its initial unionization bid, although pro-labor interests have not gone quietly into the night. Construction is expected to continue for two years, with production of Chattanooga's second vehicle expected to commence in 2016. Scroll down for the official press release from Volkswagen.
