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 SUV concept: Vision Ultimate Luxury interior teased

Mercedes-Maybach posted a teaser video of what it calls "the ultimate in luxury" last week, saying that the featured, yet-to-be-named vehicle would be presented in the Beijing Motor Show. Now there's a teaser sketch giving us a wider look of the concept's interior, as well as a name. The concept also has a name by now: the Vision Mercedes-Maybach Ultimate Luxury. We guess that might have been coming, even if the name isn't exactly concise. But, the accompanying release also informs us that the concept is a combination of a high-end sedan and an SUV, confirming that it is indeed the high-riding vehicle that's been rumored for a while. The interior sketch also shows a very wide center console with stylized grab handles, which suit the SUV dimensions and aesthetic, without being as trucklike as the Maybach G650 Landaulet's interior. As well as the lavish two-tone color scheme and the touch of wood on the door panel, the concept interior shows a wide color instrument display ahead of the driver. The gear selectors are paddle shifters next to the chunky steering wheel rim, and the controls seem to have been grouped on the wheel's spokes, leaving just a few switches on the dashboard. Autocar reports that the concept will be followed by a 2019 production version, slated to debut at the Los Angeles show at the end of this year. It would be based on the Mercedes-Benz GLS, but with a more bespoke design inside out, as hinted by the concept. Basing it on the GLS would mean Mercedes would be manufacturing it at the Tuscaloosa plant in Alabama, making it the first Maybach built in the U.S. Related Video: Image Credit: Mercedes-Maybach Beijing Motor Show Maybach Mercedes-Benz SUV Concept Cars Luxury mercedes-maybach

Experience the New York Auto Show by drone

The Autoblog team recently returned from wildly running around the Javits Center to cover all the news and debuts at the New York Auto Show. Sometimes, it's nice to take a more serene look at the exhibition floor, though, and the event's organizers are providing that exact opportunity by flying a drone through the hall. Combined with the down-tempo music, this clip feels like a form of automotive meditation. If you're going to miss the show in the Big Apple, the drone also provides a good overview at the exhibition floor, especially at the stands from Lexus, Buick, Dodge, Mercedes-Benz, Toyota and BMW. Plus, it's a fun way to see some vehicles from a completely different angle than they ever appear on the road.
