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 Concept GLA45 AMG is ready to run

This is the Mercedes-Benz Concept GLA45 AMG, and what we mean by that is, "This is the Mercedes-Benz GLA45 AMG." Mercedes has just unveiled the liveried 'concept' at the 2013 Los Angeles Auto Show, giving potential customers a very good look at the newest lunatic in the AMG asylum - a 355-horsepower, 332-pound-foot crossover that uses the same 2.0-liter, turbocharged four-cylinder engine found in the CLA45 AMG and Europe's A45 AMG.
Joined with a seven-speed, AMG Speedshift dual-clutch transmission and an AMG Performance 4Matic all-wheel-drive system, Mercedes promises a sub-five-second run to 60 miles per hour. That's not just quick for a crossover, that's quick full stop.
That sleek, lifted body has also been tweaked by the minds at AMG's Affalterbach facility. A new rear spoiler, side sills and front clip are the primary aerodynamic tweaks. Aesthetically, AMG has fitted the requisite "Turbo" badges, gloss-black accents (including exhaust tips and roof rails) and a set of 21-inch, AMG-spec alloy wheels to round out the overall package. Based on the spy shots we've seen, expect slightly toned down aerodynamics when the GLA45 AMG arrives in showrooms.

Mercedes-Maybach Ultimate Luxury SUV concept shown in leaked images

Just days ago, we posted the interior teaser image Mercedes-Maybach released of its Ultimate Luxury concept due to be presented at the Beijing Motor Show. Now photos of the entire vehicle, inside and out, have leaked online courtesy of the manufacturer. Thanks to the concept's own microsite being live for a short while, we've gotten a good look of the concept. And it's not just a dressed-up GLS by any means, even if there might be a GLS platform underneath it all: It's a high-riding four door sedan with a clearly formed trunk instead of a traditional SUV shape. There's a big waterfall grille flanked by low, aggressive three-unit headlights, and the detailing is a combination of SUV cues and something a lot more luxurious. It's not easy to design a three-box sedan that's still recognizably an SUV. Inside, there's white leather and rose-gold detailing everywhere. But the big deal is the powertrain, which in the concept is all-electric. The all wheel drive is propelled with four electric motors, with a combined power output of 750 horsepower. The battery, said to be a flat underfloor design, is good for 80 kWh and an EPA range of over 200 miles, and the vehicle's top speed is limited to 250 km/h, or 155 mph. There's DC fast charging at up to 350kW, meaning that the range can be boosted by 60 miles in just five minutes, and induction charging is also available. All in all, the vehicle reminds us of the 2009 Lagonda Luxury Utility Vehicle concept, which was also created around a three-box sedan shape and also based on a Mercedes platform, GL-Class in that case. It did not yield a production version, but maybe the Vision Ultimate Luxury will.
