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-Maybach GLS Edition 100 layers on the opulence

The Mercedes-Maybach S-Class Edition 100 was revealed yesterday, but it wasn’t the only new Maybach product to come out. No, in addition to the S-Class, Mercedes took the wraps off the Mercedes-Maybach GLS Edition 100. We didnÂ’t have the details for the SUV version right away, but we have them now. None of those details are all that surprising, though. The GLS Edition 100 is built to celebrate the same Maybach centennial milestone as the S-Class, and its appearance is essentially a copycat of the sedan. The one key difference versus the sedan is the number of cylinders under the hood. Mercedes puts its V12 in the S-Class, while the GLS soldiers on with the V8. Let the tears made of money flow for the lack of the additional four cylinders. At least everything else is largely equivalent. The GLS Edition 100 gets painted in the same Designo Crystal White and Silver Grey Pearl two-tone paint scheme. YouÂ’ll find the “Edition 100” Maybach logo on the D-pillar of the GLS. Plus, the logo makes another appearance on the stunning forged grey wheels. The interior of the GLS Edition 100 is also similar to the S-Class, in that itÂ’s finished with a special leather design that is also two-tone in nature with Crystal White and Silver Grey Pearl hides. Everybody who buys one of these Edition 100 cars gets a unique branded car cover and a special case meant to store keys and the carÂ’s paperwork. Pricing isnÂ’t detailed, but Mercedes says Edition 100 cars will be at dealers at the start of 2022 — orders will be taken in the fourth quarter of this year. Related video:
