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 has X6 in its crosshairs with the GLE Coupe

In the last month, Mercedes-Benz has taken the sheet off two versions of its GLE Coupe: the 450 AMG and Mercedes-AMG GLE63 S. The models represent the German brand's shot across the bow at the BMW X6 in the luxury-crossover-four-door-coupe segment, including the high-performance M version of the bodystyle. Not much separates the styling between the two versions. Both feature sweeping arches over the hood and roofline to create their coupe-like appearance. Up front there are huge air intakes with a wide grille on top that's bisected by the brand's traditional star. The AMG version tweaks that look with the division's A-wing grille. At the rear, there are wraparound taillights and a chrome strip. The higher performance version also sports a modified diffuser and air outlets. No matter which one buyers choose, they get a healthy amount of power nestled under the hood. The 450 AMG packs a 3.0-liter, twin-turbo V6 with 362 horsepower and 384 pound-feet of torque with a nine-speed automatic. Opting for the GLE63 means a massive boost with 577 hp and 561 pound-feet from a 5.5-liter twin-turbo V8 routing through a seven-speed auto gearbox. Either way, customers get Merc's 4Matic all-wheel drive system. The luxury crossover coupe segment is often maligned for looking awkward, but Mercedes clearly sees room to grow there. Check them both out live from the 2015 Detroit Auto Show floor in the galleries above.

Mercedes expected to announce US HQ relocating to Atlanta today

Employees at Mercedes-Benz's US headquarters in Montvale, NJ, are set to gather today for the annual president's reception. Only this year, company chairman Dr. Dieter Zetsche is expected to fly in from headquarters to make a big announcement. That announcement, according to mounting speculation, is that MBUSA is moving to Atlanta. News of the potential move first broke around three weeks ago, suggesting that the German automaker was looking to relocate its US headquarters from New Jersey to somewhere in the South, with the Atlanta area tipped as the front-runner. Now sources are expecting that announcement to be made imminently. Although the specifics of the move have yet to be made public, Mercedes is tipped to be looking at moving into either a purpose-built facility or an existing office space in the Sandy Springs area, specifically near the intersections of Georgia 400 and Abertnathy, where UPS has its headquarters. The move is said to have hinged on a substantial incentives package worth nearly $50 million put together by the Georgia state government. The state of New Jersey is said to have offered similar incentives to keep Mercedes in the Bergen County borough of Montvale, where it employs 800 in its 141,000-square-foot office complex. One advertising company even put up billboards encouraging the company to stay, but if the reports prove accurate, it looks like their efforts may have been too little and/or too late. Mercedes wouldn't be the first automaker to move to the South, where numerous foreign carmakers have been also setting up factories. Toyota is also preparing to move its US headquarters to Texas, and though already based in Georgia, Porsche is preparing to move into a new $100 million facility, complete with on-site test track, closer to Atlanta's Hartsfield-Jackson airport that has grown into a major international hub. The move on Mercedes' part would put its US base of operations closer to its factory in Tuscaloosa, AL, and the port near Savannah, GA, from which it ships out the former's production overseas.
