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-Benz to build new ML coupe-crossover in Alabama in 2015

Mercedes-Benz will expand its factory in Tuscaloosa, AL, to build the ML Coupe, a new crossover that will join its lineup in 2015. Mercedes will also ramp up production to build facelifted versions of the M-Class and GL-Class SUVs, lifting the factory's total production capacity to about 300,000 units annually in 2015. It made 185,000 vehicles in 2013. In addition to SUVs, the Tuscaloosa site also makes the C-Class sedan.
The plans come as part of Mercedes' strategy to capitalize on Americans' increasing demands for SUVs. The company said the SUV market was up 12 percent in first half of 2014, and expects it to grow at twice the rate of the regular market in 2015 and 2016.

Regulators consider adding more carmakers to Takata recall

Volkswagen's diesel emissions scandal has been getting a lot of press recently, but the Takata airbag inflator affair could be grabbing headlines again soon. According to Bloomberg, the National Highway Traffic Safety Administration is contemplating an expansion to the campaign that could add seven automakers to the 12 already affected. They are Jaguar Land Rover, Mercedes-Benz, Spartan Motors, Suzuki, Tesla, Volvo Trucks, and VW Group. To be clear, there's no recall for any of these automakers, yet. The government is simply asking for a full list of vehicles that each of them have with Takata-supplied inflators containing ammonium nitrate propellant. The agency is concerned this substance could play a roll in the ruptures. "NHTSA is considering not only whether to issue an administrative order that would coordinate the remedy programs associated with the current Takata recalls, but also whether such an order should include expansion of the current recalls," the letters say. All seven can be viewed, here. From a report supplied by Takata, the government already knows that the company supplied 887,055 inflators with ammonium-nitrate propellant to VW and 184,926 of them to Tesla. In an incident during the summer, a side airbag allegedly burst in a 2015 VW Tiguan. In early September, NHTSA put out a revised report that there were 23.4 million inflators to be replaced in 19.2 million vehicles in the US. An earlier accounting from the agency had about 34 million of the parts in 30 million cars. High humidity is still believed to be among the biggest risk factors for the ruptures. Although, if ammonium nitrate also gets the blame, some already recalled models might need to be repaired again. Related Video:
