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 moves R-Class production to AM General in Indiana

Go back a decade or two and you'd have seen the SUV market polarizing in opposite directions: hard-core off-roaders like the Hummer on the one hand, and passenger-focused crossovers like the Mercedes R-Class on the other. Now their fates are set to intertwine, at least as far as manufacturing is concerned. No longer producing Hummers, AM General (which designed and originally produced the Hummer) has been assigned the task of manufacturing the R-Class at its underused, 675,000 square-foot Commercial Assembly Plant in Mishawaka, IN – part of metropolitan South Bend. The decision was undertaken to allow Mercedes to free up production capacity at its plant in Tuscaloosa, AL, where it also produces the M-Class, GL-Class and C-Class, and where it will soon begin manufacturing the GLE Coupe. The vacation of the R-Class assembly line could be earmarked to make room for that new slant-roofed crossover (which was originally thought to be joining the Tuscaloosa plant as a fifth model) or could pave the way for another model to reach Alabama altogether. The multi-year arrangement to manufacture the R-Class makes AM General the first manufacturer contracted to build Mercedes-Benz vehicles in the US, but hardly the only one in the world. The G-Class – which could, incidentally, be characterized as the German equivalent of the Hummer – is built on Mercedes' behalf by Magna Steyr in Austria, and the company builds many of its passenger and commercial vehicles for local consumption under joint ventures in the Far East especially. The R-Class was first introduced in 2005, and though it's still built in America, it was removed from the company's US lineup back in 2012. However Mercedes confirms that, since 2013, it has been and remains available exclusively in China. That puts the R-Class in the rare position of being manufactured in the United States by (or now for) a foreign automaker but unavailable for sale here. AM General Selected As Mercedes-Benz First and Only Contract Manufacturer of Vehicles in the United States SOUTH BEND, Ind., Jan. 27, 2015 /PRNewswire/ -- AM General LLC and Mercedes-Benz U.S. International, Inc., today announced that Mercedes-Benz has selected AM General to manufacture the Mercedes-Benz R-Class luxury vehicle at AM General's world-class 675,000 square-foot Commercial Assembly Plant.

Mercedes fits new C-Class with AMG kit

It's only been a week and a half since Mercedes-Benz revealed the new C-Class, and it'll likely be a while yet before the replacement for the C63 AMG comes along. But if you want to see a preview of what it'll look like, look no further than the AMG aero kit that has just surfaced.
Expected to debut on the new C-Class at the fast-approaching Detroit Auto Show, the AMG Line Exterior Pack adds a new bumpers front and rear, side skirts, dual exhaust tips, mesh grille, aluminum window frames and - most importantly - 18-inch alloys packing upgraded brakes and fitted to a lowered sport suspension. All of which will help any C-Class look the part, even if the engine remains stock.
