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.

Tesla tires turning on Stretchla Vanagon EV conversion project

It is one thing to say you are going to Frankenstein a Tesla Model S with a pair of Siamese-twinned Volkswagen Vanagons and quite another to actually start taking your newly-acquired, smashed-up electric sedan apart in an effort to bring it back to life. Otmar Ebenhoech is doing just that, and having no small successes along the way. The Stretchla project, as it is being called, has officially started and our protagonist has put together another bit of video to document his progress and let us know about some of the different challenges he's encountered and conquered. While our original post about this endeavor featured video of the stretched Vanagon's drivetrain removal, this latest installment focuses on the Model S. Otmar received the Tesla in less-than-operable condition. Otmar received the Tesla in less-than-operable condition and has been tackling some of the basic problems one might expect to encounter: lots of error messages and an electrically disconnected battery pack. Without the aid of a manual or technical diagrams, he's removed the battery pack and discovered why it wasn't sending power to the car. Scroll below to watch the ten-minute presentation and celebrate some initial victories. You can also check out the official Stretchla blog for more photos and updates, including the most recent one that discusses how he talked himself into paying (*spoiler alert) $42,000 for a wrecked, non-functional electric car, along with more recent struggles with the steering rack. Hit us up in the comments to let us know what kind of trouble you would get into with a Model S drivetrain of your own. This content is hosted by a third party.

BMW, Ferrari, VW cars use tungsten mined by terrorists

Bloomberg Markets is reporting that BMW, Volkswagen and Ferrari have been using tungsten ore sourced from Columbia's FARC rebel terrorists. The extensive story focuses on Columbia's illegal mining trade and calls into question the provenance of the rare ore that is used not only in crankshaft parts production, but is also found in the world's computing and telecommunications industry for use in screens.
The ore is mined by the FARC (Fuerzas Armadas Revolucionarias de Colombia, or Revolutionary Armed Forces of Colombia - People's Army), and exported to Pennsylvania, where it is refined. The refined ore is then sent over to Austria, where a company called Plansee turns it into a finished product. Now, it's important to note that we aren't talking about the world's supply of tungsten here. In 2012, Plansee's American refinery purchased 93.2 metric tons of tungsten, valued at $1.8 million. That's peanuts, with the entire Colombian tungsten mining industry producing just one percent of the world's supplies.
That doesn't make indirectly supporting FARC any more acceptable, though. BMW, VW and Ferrari are all committed to not accepting mineral supplies from the Democratic Republic of Congo, which is also in the grips of a guerrilla insurrection funded, in part, by illegal mining. The same commitment would figure to extend to Colombian mining, but as BMW points out, it's difficult for a multi-national manufacturer to know where every item in its supply chain comes from. A company spokesperson says as much, telling Bloomberg, "These few grams out of the billions of tons of raw materials passing through the BMW supply chain are of no practical relevance."
