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 Ultimate Luxury fully revealed, tea set and all

Mercedes has officially unveiled its Mercedes-Maybach Ultimate Luxury concept following a leak of most of the details last week. As we learned last week, the unusual looking sedan-SUV crossbreed is fully electric with four motors producing a whopping 750 horsepower. Combined with an 80 kWh battery, Mercedes estimates it should have a range of over 200 miles on the European test cycle. It also can handle extremely fast charging from DC chargers outputting 350 kW. Mercedes claims this allows it to gain 60 miles of range in 5 minutes. But there are a number of interesting details that weren't leaked. Many of them have to do with the car's Chinese inspiration, which is perhaps not that surprising for a car that makes its debut in China. The body style is the first influence, which Mercedes says combines the sedan and SUV, the best-selling car classes in the country. On the inside, there are a pair of cues inspired by China. The first is the ebony wood trim that Mercedes calls "Magic Wood." The company says it's very similar to that used in Chinese furniture. In the back, between the two highly adjustable white leather seats with rose-gold stitching, is a complete tea set. And not only does it contain all the containers for tea, but it actually has a variety of teas on offer. They're there to be used in conjunction with the car's relaxation modes that combine lighting, music and scents to set the mood. It's hard to say whether this concept will spawn a production model, since the body style is unlike any currently offered by Mercedes-Benz. But with the crossover SUV market staying hot, and competitors such as Audi and BMW bringing out extra-large SUVs, we wouldn't be surprised if Mercedes eventually offers at least a Maybach-level version of its GLS-Class, if not its own model.

Mercedes S-Class Magic Body Control ad is clucking awesome

This is a new ad from Mercedes-Benz. At no point does it show an automobile. Instead, it stars animals, but not the sort you might normally see in car commercial. This ad is all about chickens. It is bizarre, to say the least, with Diana Ross and the Supremes belting it out in the background, but it all kind of comes together when you realize just what Mercedes is hawking (yeah, pun intended).
It's for the manufacturer's Magic Body Control, found on the new S-Class. The system basically analyzes the road and prepares the suspension accordingly, leading to a ride that is, in the words of our own Chris Paukert "nothing short of spooky." You can read about it in our full review of the 2014 S550. Take a look below for the 53-second spot.
