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.

1000-hp Mk1 VW Golf is terrifyingly cool

There are plenty of things to love about the Mk1 Volkswgen Golf. The machine's horsepower isn't one of them. From the factory, the little hatch cranked a breathy 112 horsepower from the most robust form of its 1.8-liter four-cylinder engine. Boba motoring, however, has taken that figure and multiplied it by a factor of nearly 10. If 1,000 horsepower sounds terrifying in a machine with a wheelbase of just 94.5 inches, it should. A massive Garrett GTX4202R turbo force-feeds the little mill through a tweaked 16-valve KR head. The crew calls the beast the 16Vampir, and we think that's fitting.
Of course, we'd wager you quit reading right about the time you set your eyes on that headline. Those of you who've stuck around this long can point yourselves below to see the maniacal creation in action. You won't be disappointed.

Prop-driven VW Beetle hopes to land in Bonneville [w/video]

Sometimes you meet folks who, when they tell you "Hey, I have an idea," your reflex response is to stop what you're doing and tell yourself, "Get ready...." We imagine Mike Niemans is one of those folks, and the idea in question is putting a tank engine on a Type 1 Volkswagen Beetle. Not just any old tank engine - as if there were such a thing when we're talking about putting them in cars - but a 668-cubic-inch, 220-horsepower radial engine built by Continental in 1941 and procured from an M2 tank.
In the image above Nieman is using the tank clutch hub to get the motor set up, but in one of the images below you can see what really belongs back there is: a two-inch, reverse-pitch prop taken from a wind generator. He says there's enough mojo with the propeller action to get the car rolling down the runway like a jet when he gives it gas - and speaking of gas, the engine's been refitted to run on propane.
After a few safety tweaks Nieman's going to take the matte-black Beetle to Bonneville, "put the prop on, let her go and see what happens!" We can't wait to see the video of that. There are two shakedown videos below to get you ready.
