Volkswagen Golf Wagon caught completely uncovered

Without a lot of information to go with them, our camera-toting spies have captured some new images of a Volkswagen Golf wagon variant that is almost completely undisguised. In fact, the one piece of camouflage on the tidy wagon would probably have gone unnoticed to most casual viewers. Look closely at the rear three-quarter view of the car and you'll notice that the apparent taillight clusters are actually fakes - the outline of the real units is faintly visible behind the blue bodywork and the sticker-like fake taillights.
It's a good guess then, that this Golf wagon (called a Golf Kombi by our spy photographer) is a prototype that's pretty far along in the development cycle for Volkswagen. We can't be sure what impact this will have on the company's small wagon offering here in the US, but we'd be pretty surprised if something very like this didn't end up as the next Jetta SportWagen. We might well have more information on that front, after we visit Geneva next week.

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.
