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.

Hollywood stars drink hydrogen B-Class F-Cell emission water in Death Valley [UPDATE]

A plug-in electric vehicle can be used to power a house during a winter storm, but if you're more worried about the heat of, say, Death Valley, then maybe you'll want a Mercedes-Benz B-Class F-Cell along. That's the message of a new video from Daimler and starring Diane Kruger (Inglourious Basterds) and Joshua Jackson (Fringe) that promotes the company's hydrogen-powered car. The gist? You can drink the tailpipe emissions. The two Hollywood stars drove in Death Vally without any water in their F-Cell but had a special tank hooked up to the tailpipe to collect the H2O drips as they drove in 100+ degree temperatures. There's a reason these two actors were chosen, since they've been driving an F-Cell in their daily lives for two years, according to the Diamler press release. The text is, shall we say, a bit hyperbolic - "Their lives rely on the emissions of the B-Class F-CELL" it says, totally ignoring the film crew that is obviously along for the ride and more than likely had a few bottles with them. Also, when the California Fuel Cell Partnership promoted the same idea a few years ago, it clarified that, "A fuel cell doesn't produce enough water to fill your glass. ... If fact, fuel cells produce about the same amount of water as gasoline vehicle – about 1/3 cup for a full day of driving." Thus, this whole thing is a Hollywood stunt, but it's a visually effective one. See for yourself in the mini-movie below. UPDATE: Daimler has told AutoblogGreen that there was no "extra Hollywood magic" needed for the water collected in the video. Instead, Madeleine Herdlitschka, who works at global communications for Mercedes-Benz Cars, said, "Considering the technical characteristics, the Mercedes-Benz B-Class F-CELL emits about 9 kg of water vapor per kg of hydrogen while driving. The vehicle has a hydrogen capacity of about 3.7 kg, what is sufficient for a max. of about 400 km of range. A tailor-made construction, designed by the production company Markenfilm Crossing in cooperation with our fuel cell experts, made it possible to collect the water in a tank - previously cooling the vapor with a specially designed pipe system."

Aston wants to build DBX on its new platform, not Mercedes'

Aston Martin is proceeding with plans to launch the DBX as its first production crossover. It just can't say at this point what it will be based on. Speaking with Automotive News Europe, Aston's new CEO Andy Palmer indicated that basing the DBX on a Mercedes SUV platform would not be its first choice because they "clearly sit in a very different space to the one we want to go" with the DBX. Instead, the company's first choice would be to build the crossover atop the new platform it's developing for its sports cars. "It just depends how high off the ground it could go," said Palmer. "I don't exclude the possibility of using some [Mercedes] parts, but I would say very much the primary route is our platform." The prospect of building an Aston SUV on Mercedes architecture – namely that of the GL-Class – has been on the table for some time now. The Lagonda SUV concept it showcased at the Geneva show in 2009 was based on the GL, and the two automakers have been forging a tightening alliance in the years since. The British automaker's next-generation engine is to be built by Mercedes-AMG, and it is expected to source other components from the German automaker as well. For its part, Mercedes has been taking a sportier approach with its latest crossovers, as demonstrated by the GLE Coupe that debuted before the more conventional version and the Concept GLC Coupe that previewed the GLK's replacement in Shanghai last month. Aston Martin, on the other hand, is building a new sports car platform that will underpin its next generation of luxury GTs, replacing the long-serving VH architecture that has served for decades as the basis for its entire model line. Perhaps the most surprising of ANE's report, though, is that Aston seems to be proceeding with plans to build the DBX apparently without even knowing what platform it will use.
