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 Makes A Mighty Little Sedan
We got overexcited when the W203 Mercedes-Benz C-Class sedan came out in 2001, calling it the "Baby Benz" when it really wasn't. We knew that, too, but our enthusiasm for a model more like the old 190 of the '80s was so strong that we were willing to stretch the first-gen C-Class to fit that mold. Today, the C-Class has done what all German premium cars do: grown in size. In this case, grown to satisfy the market intentions of the previous E-Class.
There was the tall A-Class sold from 1998 through 2010, but we never considered that a serious small Benz in the proper spirit, nor was it ever offered in the US. Regardless, we've been craving a smaller, premium, sexy sedan all the while.

If you're a Daimler exec, you'll soon have to drive an EV

Luckily, for Daimler's "senior level" managers, the company has a lot of plug-in vehicle options. Lucky because "in the future," these managers will have to drive the company's electrified vehicles. This most likely means a plug-in hybrid – something like the C 350 e or the GLE 500 e 4MATIC – but it could also be the all-electric and peppy Smart ED or the B-Class EV. Board member Ola Kallenius said in a statement (available below) that this new policy, "We are continuing on the path of zero-emission driving with consistency. This is why we are making electric mobility an integral part of the everyday lives of our top management to set an example and to provide a clear role model." It's a big change from five years ago, when Daimler's director of fuel cell and battery drive development, Christian Mohrdieck, was willing to talk up the drawbacks EVs face. Even a year ago, Daimler CEO Dieter Zetsche explained the financial hardships involved in making EVs. But, EV technology continues to change, and so, perhaps, do the attitudes inside Daimler. As EV advocate Chelsea Sexton said on Facebook regarding this new policy, "This should be standard procedure in any automaker seeking a leadership role in the plug-in vehicle movement. Commitment starts at the top."

Furthermore, Daimler is this year set to invest a further 30 million euros into extending the company's own charging infrastructure across many of its sites. This will also benefit employees, who have access to a growing range of vehicles with alternative drive systems. Stuttgart. It represents a further commitment from Daimler to an electric future for mobility: "We are continuing on the path of zero-emission driving with consistency", states Ola Kallenius, member of the Board of Management of Daimler AG responsible for Mercedes-Benz Cars Sales and Marketing, about the importance of the current initiative. "This is why we are making electric mobility an integral part of the everyday lives of our top management to set an example and to provide a clear role model." The agreement applies to the company's senior levels of management and focuses on plug-in hybrids.
