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.

2013 Mercedes-Benz SL65 AMG

Make way for the 2013 Mercedes-Benz SL65 AMG, the most wonderfully preposterous car I have ever driven.
There is absolutely no reason why any two-seat roadster should be fitted with a twin-turbocharged 6.0-liter V12 developing 621 horsepower and 738 pound-feet of torque, but I sure am glad that Mercedes-Benz doesn't see things that way.
Drop into the leather-lined cockpit of this $213,145 provocateur, floor the accelerator pedal as I did over and over again, and 60 miles per hour falls in a traction-limited 3.9 seconds. Top speed has been electronically held to 186 mph (this apparently saves Gulfstream jet owners from embarrassment). Forget the SL550 and SL63 AMG, the valets will trip over themselves attending to the tycoon driving this thoroughbred - it's the real deal.

Vision Mercedes-Maybach 6 to debut in Monterey

Mercedes surprised the car world last week when it teased an enormous, Maybach-badged coupe concept. Now we have a name and a debut date. Mercedes released the info in a second teaser image posted to its Facebook page. Called the Vision Mercedes-Maybach 6 – "Vision" equals concept and "6" denotes the length in meters – the new two-door will debut at Pebble Beach on Thursday. So yeah, here's another reason to get excited about Monterey Car Week. As for the teaser image, it's a head-on shot as opposed to the profile view that Mercedes released last week. The new view supports our theory that the super-skinny mirrors are cameras, and the shot also reveals new styling touches. The most noticeable are the very thin, un-Mercedes-like headlights – they flank a prominent, heavily polished waterfall grille that marks a significant departure from recent Mercedes products. A traditional Mercedes hood ornament sits above the grille's small "Maybach" designation. Kicking up the exposure in Photoshop doesn't reveal too much more detail – unlike last week's profile image – aside from a set of chrome strips that run along the sides of the hood. Autoblog's Monterey Car Week crew ships out for the left coast soon – expect more on the festivities, including the Vision Mercedes-Maybach 6's debut, later this week.
