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 GLE Coupe to feature in Jurassic World

It was back in 1997 that Mercedes first got into the crossover game with the launch of the M-Class, and most of us got our first look at the luxury high-rider when it debuted on the big screen in the Jurassic Park sequel The Lost World. It's been 18 years since that event, but now its successor is set to appear in the revival of the once-popular movie franchise. Come June 12, moviegoers will be able to catch the new Jurassic World film at their local theaters, but the dinosaurs will have to share the spotlight with the new GLE Coupe. The slant-roofed crossover that'll share its underpinnings with the M-Class' successor and challenge the BMW X6, will appear in the film in GLE 450 AMG Sport guise, and Universal Studios apparently did a good enough job keeping the Mercedes under wraps during filming until its release just a month ago. Mercedes Continues Its Decades Long Relationship with Universal: Mercedes-Benz GLE Coupe launches in Universal Pictures' Jurassic World Stuttgart, Jan 08, 2015 Stuttgart. On-screen, multiple Mercedes-Benz vehicles are once again in on the Jurassic action. Twenty-two years since the events of the original film, Steven Spielberg returns to executive produce the long-awaited next installment of his groundbreaking Jurassic Park series, Jurassic World. During their adventures in the jungles of Jurassic World, the characters played by Chris Pratt and Bryce Dallas Howard put their trust in the off-road capabilities of various Mercedes-Benz vehicles – especially in the all-new GLE Coupe, which appears in its series-look for the first time. Colin Trevorrow directs the epic action-adventure from a screenplay he wrote with Derek Connolly. Frank Marshall and Patrick Crowley join the team as producers. Jurassic World will be released in 3D by Universal Pictures on June 12, 2015. The partnership continues the relationship between Universal and Mercedes-Benz, first forged in 1997's The Lost World: Jurassic Park, when Mercedes introduced the M-Class vehicle. "We are delighted to have been able to support this epic action-adventure with our vehicles," said Dr. Jens Thiemer, Head of Marketing Communications for Mercedes-Benz Cars. "Our wide range of SUVs in particular fit perfectly with Jurassic World's various requirements, with the focus on our new trendsetter, the GLE Coupe." Above all, it is the new GLE Coupe that shows off its best side.
