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.

Brabus takes Mercedes-Maybach even further

Hard as it may be to imagine for most, even the flagship Mercedes-Maybach S600 won't be enough for some. And those individuals can now turn to Brabus to customize their limousines even further. The latest tuning package includes an array of enhancements, starting with the engine. That's where Brabus has installed all the upgrades from the Brabus Rocket 900, boring the 6.0-liter twin-turbo V12 out to 6.3 liters, and producing a massive 887 horsepower and 1,106 pound-feet of torque. That'll propel the limo up to an Autobahn-crunching top speed quoted at 217 miles per hour, reaching 62 in just 3.7 seconds. Buyers going for the less potent Maybach S500 offered in certain markets can also opt for the Brabus B50-540 performance kit, which offers 83 extra hp and a further 88 lb-ft of torque. Brabus has also fitted a choice of 21-inch wheels, retuned suspension dropped by an inch, a full aero kit, and new radiator grille. And as sumptuous as it is already, the tuner is also offering upgrades to the interior with special leather and Alcantara upholstery, wood and carbon-fiber trim, and its full iBusiness suite. All of which promises to make the flagship Mercedes even more expensive, of course, but if there was ever an example of "if you have to ask, you can't afford it," surely the Maybach is it. BRABUS refines the new Mercedes-Maybach 662 kW / 900 HP, 1,500 Nm, top speed 350 km/h plus, high-tech forged wheels, sporty-elegant design and even more luxurious BRABUS fine leather interiors The new Mercedes-Maybach represents the absolute pinnacle of state-of-the-art automotive engineering. Nonetheless, even this luxury sedan offers room for individual refinement, which BRABUS (Brabus-Allee, D-46240 Bottrop, phone + 49 / (0) 2041 / 777-0, fax + 49 / (0) 2041 / 777 111, internet www.brabus.com) realizes with a select team of the best engineers, designers, technicians and master craftsmen. The BRABUS ROCKET 900 6.3 V12 twin-turbo increased-displacement engine provides the Mercedes-Maybach S 600 with an enormous rated power output of 662 kW / 900 HP (887 bhp) and a peak torque of 1,500 Nm (1,106 lb-ft). Top speed is in excess of 350 km/h (217 mph). To match the extreme performance of the luxury liner, the appearance of the four-seat car receives some sporty-elegant emphasis with BRABUS aerodynamic-enhancement components and BRABUS Monoblock "PLATINUM EDITION" 21-inch forged wheels. Another BRABUS domain is exclusive interior design.

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.
