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.

Volkswagen unveils sportier Passat Performance Concept ahead of Detroit debut

Ahead of its official unveiling at next week's Detroit Auto Show, Volkswagen has released some preliminary details and images of its Passat Performance Concept - a car that, as its name suggests, adds a little more spice to the automaker's midsize sedan formula. VW makes no mention of any production intent for this road-ready-looking sedan, simply stating that the Performance Concept is a way to "explore this practical four-door's sportier side."
It certainly doesn't look too sporty, the only visual upgrades being larger 19-inch wheels, dual exhaust, bi-xenon headlamps with VW's Advanced Front Lighting system, LED taillmaps and carbon-look mirror caps. Inside, there are carbon interior accents and two-tone leather upholstery. But no matter, the real upgrades for this mightier Passat are found below the sheetmetal.
Powering the Performance Concept is a 1.8-liter turbocharged four-cylinder engine, churning out 250 horsepower and sending its grunt to the ground via a six-speed automatic transmission. For reference, that's 80 more horsepower than the Passat's base 2.5-liter inline-five, but 20 horsepower less than the potent 3.6-liter VR6. As for other performance upgrades, Volkswagen has fitted the car with a lowered sport suspension and revamped electronic steering, which should indeed add a bit more dynamic feedback to the already nice-driving sedan.
