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.

TRANSLOGIC 150: Volkswagen XL1

How do you build the world's most fuel-efficient production car? Start with the world's most aerodynamic design. The Volkswagen XL1 is capable of 261 miles per gallon thanks to its sleek shape and ultra efficient plug-in diesel hybrid powertrain. The downside is that only 250 will be made and none will be sold stateside. That didn't stop us from taking our turn behind the wheel of this truly revolutionary ride.

Touring the Volkswagen Museum in Wolfsburg

Forgive the ribbon up top - this isn't so much of a Read This as a Look At This. Ran When Parked took a tour of the sprawling Volkswagen Museum in Wolfsburg, and while there's a spot of text about the different and unique vehicles on display in the rotating exhibits, it's largely the collection of pictures of odd, one-off VW-badged cars and vans that excites. If you're a fan of the weird and wild, this is a post you'll want to look at.
As RWP points out, this is the larger, but less busy, museum targeted purely at Volkswagen products. The smaller AutoStadt museum, meanwhile, covers a much broader swath, with products from other Volkswagen Group members.
