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.

Online Find of the Day: Lexus-engined Mercedes pickup is a vintage hybrid

You have to love someone who gets incredibly committed to a very weird idea. What you see for sale here is a right-hand drive 1971 Mercedes-Benz 220D in South Africa, but this old Mercedes is now converted into a pickup, complete with bed cover, and there's big secret under the hood, too.
The pickup conversion appears well done based on seller Sedgefield Classic Cars' photos. Even the tonneau cover fits well. You could almost believe that this Mercedes lived its life as a Chevrolet El Camino-like pickup from the very beginning.
However, the rear-quarters conversion might not be the weirdest thing about this Mercedes. The original diesel is gone from the engine bay in favor of a Lexus V8. It seems really odd to pop the hood and find a Japanese mill in this German car, but the photos make it look like a fairly well performed swap. So, bravo to the crazy thinking. According to the seller speaking to Autoblog by email, "as far as we can establish, this was done a few years ago, with all Lexus components."

The dealer order guide for the 2014 Mercedes-Benz CLA has made its way online courtesy of the crew at CLAForums.com, and not only does it shed light on the ways buyers will be able to configure the entry-level sedan, it talks specific option pricing.

The CLA will be available with a number of active safety systems on board, including lane departure warning, adaptive cruise control, park assist and blind spot assist, to name a few.
The new sedan comes in 10 colors, including a very dashing purple Mecedes-Benz calls Northern Lights Violet, and there are a total of four interior trim finishes. The automaker hasn't released final pricing of all models just as of yet - we do know from Mercedes' Kate Upton Super Bowl ad that the car will start at $29,900 - but you can check out individual option and package pricing in the gallery.
