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.

McLaren F1 poaches Jost Capito from VW WRC

The executive shuffle continues at the McLaren Formula 1 team with news that Ron Dennis has lured Jost Capito away from his position as head of Volkswagen Motorsport. Capito will become the CEO of McLaren Racing, replacing Jonathan Neale who took the position on an interim basis at the beginning of 2014 to replace Martin Whitmarsh. Whitmarsh, who had been with McLaren for 24 years and spent five of them as F1 team principal, left the company after being moved out of the CEO position. Neale, on the other hand, who has been with McLaren Racing since 2001, is moving over to the newly created position of COO of the McLaren Technology Group. Capito left the Ford SVT division in 2012 to run VW Motorsport, and has spent the past three years shepherding the brand's World Rally Championship to three consecutive driver's and manufacturer's titles. Before that, his lengthy racing resume includes developing high-performance BMW engines, winning the Dakar Rally as a co-pilot, executive positions with Sauber in the early nineties, and managing Ford's WRC team. Dennis, who first approached Capito last summer, called him, "extremely impressive, competitive, and ambitious." The Woking team has some great parts, but it hasn't been able to make the most of them comprehensively since the end 2012 season. Autosport says that Capito has the ability to make the best pieces work together, which will probably be his biggest challenge at McLaren. Capito will remain at VW until a successor is found.
