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.

2016 Mercedes-Maybach S600 Review [w/video]

"Hindsight is 20/20" is a handy yet disingenuous cliche. The flaw is that hindsight is only instructive up to the moment you would have made a different, perhaps better, decision. At the moment of that deviation the past goes in another direction, one that you can't peer back into because you didn't experience it. So when we say we wish Karl Benz's eponymous firm had produced the Mercedes-Maybach S600 in 2002 instead of the gilded blunder of the separate Maybach brand and its 57 and 62 sedans, we just can't know if the formula would have worked 13 years ago. But we do know the formula adds up superbly right now. A little history: Wilhelm Maybach helped Gottlieb Daimler build a high-speed, four-stroke internal combustion engine in 1885. Eventually Maybach went to work for Daimler's new car company and designed the first Mercedes, the 1901 35-hp model considered the world's first modern car. Maybach left the company after Daimler's death, started a company building zeppelins, then joined his son to start the Maybach car company. Together they developed super luxury cars including the DS8 Zeppelin models that competed with Rolls-Royce. A reviewer in 1933 wrote, "The Maybach Zeppelin models rank among the few cars in the international top class. They are highly luxurious, extremely lavish in their engineering and attainable only for a chosen few." It's a whopping 28 inches shorter than the departed Maybach 62, but 8.2 inches longer than a standard S-Class. As is this Maybach S600. It's a whopping 28 inches shorter than the departed Maybach 62, but since it's 8.2 inches longer than a standard S-Class, there's a very different driving experience. Two-thirds of a foot isn't much, but the Maybach is 639 pounds heavier than an S550, or 231 pounds heavier than a standard S600. From the driver's seat we could feel every additional pound and inch over those other models. It is as if Mercedes threw out the aluminum and steel and chiseled this sedan from basalt. We've driven scanty few cars where we've been genuinely glad for blind-spot detection and 360-degree cameras – this is one of them. The Maybach's wheelbase is four inches longer than that of a Bentley Mulsanne, even though the overall car is almost five inches shorter than the Big B. That long wheelbase translates into tranquil steering response – the S550, S600, and Maybach S600 all have the same 2.3 turns-to-lock, but this sedan feels like it takes more effort. It even looks heavy.
