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.

Race Recap: 2013 Japanese Grand Prix flips several scripts [spoilers]

Japan's Suzuka circuit is a great track that all the drivers love, but it doesn't usually provide the most thrilling, head-to-head racing. Where it does excel, however, is with surprises and "What just happened there?!" moments, and this year it was no different.
It started with Mark Webber in his Infiniti Red Bull Racing out-qualifying his teammate Sebastian Vettel for the first time this year. They were followed closely by Lewis Hamilton in the first Mercedes-AMG Petronas, the still-solid Romain Grosjean again outdoing teammate Kimi Räikkönen, Felipe Massa racing for another seat in Formula One and putting his Ferrari in fifth, then Nico Rosberg in the second Mercedes, Nico Hülkenberg in the first Sauber, Fernando Alonso in the second Ferrari, and Räikkönen continuing to do himself no favors by qualifying tenth.
For the second year in a row, the lights going out was the cue to start the first corner action...

Erebus Motorsport Mercedes E-Class V8 Supercar completes the field [w/videos]

Ford, Holden and Nissan introduced their V8 Supercar challengers a while back. Erebus Motorport, whose racing program got the green light not even 120 days ago, has finally shown off the Mercedes-Benz E-Class racer that will complete this year's field of entries. The first AMG race car ever to be built outside of Germany, it's an Australian-built tube-frame chassis specced to the series' Car of Tomorrow rules, fitted with body panels that channel the E63 AMG.
Supported by AMG Customer Motorsport, the 5.0-liter engine is provided by HWA in Germany, the racing arm of AMG. Regulations dictate that it have roughly 650 horsepower, a redline between 7,000 and 7,500 rpm and a torque curve that matches the parity baseline set for all cars.
Lee Holdsworth, Tim Slade and Maro Engel will drive the three team cars, each with different sponsors. Their first showing will be at the Clipsal 500 on March 3 in Adelaide, here in the US we'll get to see them in May at the Circuit of the Americas. Check out the videos below of the Erebus car starting up at its launch, and footage of all of this year's cars doing pre-season testing on track together.
