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.

Petrolicious relives history with Stirling Moss and his Mercedes SLR

We take it as a given that lap records will keep getting beaten. That's just the way things work: the development of racing cars proceeds at breakneck speeds, dwindling lap times down over the ages. Not at the Mille Miglia, though. The legendary Sir Stirling Moss won the famous Italian race together with journalist Denis Jenkinson in 1955, recording an almost unfathomable average speed of nearly 98 miles per hour in the Mercedes 300 SLR bearing the number 722 – the inspiration behind the extreme SLR McLaren Stirling Moss edition speedster that debuted seven years ago. Nobody (not even Moss himself) managed to beat that time in the subsequent two years before the race was shut down for good. It was only revived decades later as an historic rally that's more about consistency and, by its nature, doesn't put that record in contention. This year's event is coming up soon, so the cinematographical artisans at Petrolicious caught up with Moss and that legendary SLR – perfectly preserved as it has been by Mercedes – for a drive down memory lane.
