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.

Maybach could become Mercedes-Benz sub-brand

When you're arriving in a twin-turbocharged, twelve-cylinder Maybach limo, there's no reason you should ever have to be late. Except, maybe, to make a fashionable entrance. But up at the corporate level, the entire Maybach brand is being slowed down as critical decisions about its future are being undertaken.
Last week, we reported that a decision on what path Maybach would take going forward would be due at the start of next month, but the latest reports indicate that the timeframe has been extended as further options are being considered.
The previous options under consideration were twofold: either relaunch the brand with production outsourced to Aston Martin - which suddenly finds itself with excess production capacity - or shut it down completely. And those are still two very real options. Word has it that Aston has put together four concept cars for the Daimler brass to consider, all based on the next-generation S-Class platform (and thankfully not the old one).

Mercedes GLE to debut in NY, will get plug-in variant

On the eve of the 2015 Detroit Auto Show, Dieter Zetsche, Chairman of Daimler AG, said that 2015 will be the "Year of the SUV" at Mercedes-Benz. This means a host of new and updated sport-utility and crossover models, kicked off with the debut of the GLE-Class Coupe (pictured above) – in 450 AMG Sport and Mercedes-AMG GLE63 variants – here in the Motor City. But there's far more in store throughout the year. First, Mercedes has confirmed it will debut the non-coupe GLE-Class – the M-Class replacement – at the New York Auto Show in April. It will share most of its architecture with the GLE Coupe revealed here in Detroit, but will also come with a plug-in hybrid option. Mercedes-Benz debuted an S-Class Plug-In Hybrid at the Los Angeles Auto Show last November, and will expand this technology to other core models in its range. First, we will see the C350 Plug-In Hybrid, which also makes its debut here in Detroit. Beyond that, Mercedes has confirmed that the GLE-Class will benefit from a plug-in option, as will the upcoming GLC-Class crossover – the renamed replacement for the GLK. No official timing has been given for the GLC, but Mercedes confirms that both it and its largest utility vehicle – the GLS-Class (currently known as the GL-Class) – will debut "later this year." Year of the SUV, indeed.
