Carlsson SLK 340 Judd is winged up for hill climb glory

Carlsson has been expertly tuning Mercedes-Benz products for more than 20 years now, but we can't say as we remember the outfit turning out anything quite so racy as this SLK 340 Judd that it has brought along to the Geneva Motor Show this year.
This SLK is meant for competition, obviously, and Carlsson has already booked the car to race in several hill climb events in the E1 category. The purpose-built racer should have a fighting chance to do well in said races, with a shape vetted in wind tunnel testing for maximum downforce, the SLK uses a carbon-fiber bodyshell to help achieve a curb weight of just about 1,720 pounds.
The featherweight SLK's name comes from its 3.4-liter V8 engine, which churns out a wicked 610 horsepower to go with its 317 pound-feet of torque. A Hewland transmission with paddle shift operation manages all of the thrust.

First official shot of Mercedes S-Class Coupe leaks out

With the official debut for the Mercedes-Benz S-Class Coupe expected tomorrow, it shouldn't be a surprise that some clicky fingers have already managed to uncover an official image of the car before the unveiling. Outside of this sole image, though, there's precious little detail on the new car.
First posted by Autofilou and then picked up by WorldCarFans, the production S-Class Coupe isn't far off from the concept car we saw a few months back in Frankfurt. Like the concept, the leggy production model appears related, albeit distantly, to the S-Class Sedan. The hood and front fascia are longer and lower, befitting of a two-door, while the character lines in the profile are more pronounced. Obviously, the beltline and slim, B-pillarless greenhouse are coupe-only items. We can't see any details on the back of the car, although it does appear that the long hood has a correspondingly short rear deck.
We'll have all the details on the official replacement for the CL-Class when it makes its full debut tomorrow. Until then, what do you think of this lone image? Does it appear that Mercedes has got it right? In terms of design, where would you rank this with the departing CL-Class? Have your say in Comments.

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.
