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 considering GLA-based crossover coupe

BMW opened a whole Pandora's Box when it introduced the X6 back in 2008. Sure it made little sense, sacrificing all that "utility" for a little more "sport," but it's been a solid success for BMW - especially considering the nominal expense it cost to develop the X6 on top of the X5 on which it's based. Little wonder that, while BMW has already followed up with a smaller version in the form of the X4, other automakers are starting to catch up. And that includes Mercedes-Benz.
The German automaker is preparing to launch a new MLC, based on the M-Class but with a sportier silhouette, and previewed it with the Concept Coupe SUV at the Beijing Motor Show. But that's just the start, according to the latest report from Automotive News Europe.
Mercedes is reportedly considering spinning off an entire line of crossovers more for use on the road than off it. Which may go without saying for most crossovers on the market, but considering the Geländwagen with which Mercedes got its start in SUVs, would mean an even further departure than it has undertaken already.

Mercedes-Benz GLA45 AMG spied in Sweden

We've spotted the all-new Mercedes-Benz GLA testing a couple times in recent months in getting closer to production form and shedding camouflage, but now it looks like we're see our first look at the AMG version of this compact crossover. The low ride height might trick some into thinking that we're just seeing the already-confirmed A45 AMG out testing, but the unique beltline, rear doors and side windows confirm this is some version of the GLA-Class.
What makes us so confident that this is the AMG model? Well, for starters, this prototype has beefier brakes with cross-drilled front and rear rotors and bigger front calipers, but it also sports dual exhaust outlets poking through the rear fascia and a suspension that has been lowered considerably. Our spy shooters said that this car's exhaust note made it almost certainly an AMG model.
Just to be clear, the GLA AMG will not be powered by a 4.5-liter engine. The closely related A45 AMG will carry the "45" in its name to celebrate the first 45 years of AMG, and our sources seem to indicate the AMG version of the GLA will do the same. We're expecting this sporty crossover to produce as much as 350 horsepower from its AMG-tuned four-cylinder engine, and like the all-new E63 AMG, it could very well come standard with 4Matic all-wheel drive.
