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.

Mercedes sues Ferrari-bound F1 engineer for stealing secrets

Mercedes is suing one of its Formula One engineers, one Benjamin Hoyle, claiming he was planning to take sensitive data to a competitor. An experienced powertrain engineer, Hoyle came to Mercedes AMG High Performance Powertrains in 2012 with previous experience at Prodrive and Cosworth. One of four team leaders at the company, Hoyle headed up the performance application department until he notified his employers of his intention not to seek renewal of his contract that expires at the end of this year. Once they found out that Hoyle was switching to Ferrari, the higher-ups at Mercedes reassigned him to other, less sensitive duties, however Hoyle was reportedly discovered accessing race reports and other sensitive data relating to the performance of the team's engines. In response, Mercedes has filed suit against Hoyle, claiming that he "and potentially Ferrari have gained an unlawful advantage." The German automaker is seeking the return of all documents and the payment of its legal fees. It also seeks to prevent Hoyle from working for another F1 team throughout next season. Mercedes AMG High Performance Powertrains is the Daimler's F1 engine division. Based in Brixworth, UK, it was founded back in 1983 together with Ilmor before Mercedes bought it outright. Aside from the company's own works team, the outfit this year powered Williams, Lotus, and Force India, and previously worked with McLaren as well as Sauber. This is not the first time that a case of industrial espionage has emerged in F1. A similar controversy erupted in 2007 surrounding engineers Nigel Stepney and Mike Coughlan. The highly publicized incident became known as "Spygate" or "Stepneygate" and involved the illegal sharing of secrets between Ferrari, McLaren, and Renault.
