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.

Lewis Hamilton wins in Hungary to stretch F1 title lead over Sebastian Vettel

BUDAPEST (Reuters) - Formula One world champion Lewis Hamilton won the Hungarian Grand Prix from pole position for Mercedes on Sunday to go into the August break with a 24-point lead over Ferrari rival Sebastian Vettel. Vettel was runner-up in Hungary, 17.1 seconds behind, and survived a late collision with Hamilton's team mate Valtteri Bottas who also banged bodywork with Red Bull's Australian Daniel Ricciardo. The victory was Hamilton's record sixth in Hungary, fifth of the season and 67th of his career. Ferrari, mourning the death of former chairman Sergio Marchionne, had Kimi Raikkonen finish third to complete a podium of champions on a dry and sweltering afternoon at the Hungaroring outside Budapest. In a race effectively decided by Saturday's wet qualifying, when Mercedes locked out the front row of the grid against expectation, Hamilton was never challenged. "We came here knowing Ferrari would be really quick this weekend so to come out with these points, we'll definitely take it as a bonus," said Hamilton in a pitlane interview after embracing team members. "I'm really happy with how strong it's come in the last couple of races. We've got to come strong in the next half," added the 33-year-old, who won in Germany from 14th place on the grid a weekend earlier. After 12 races, Hamilton has 213 points to Vettel's 189. Tire strategies were also crucial at a relatively slow and twisty circuit where overtaking is always difficult, with track temperatures hovering around 50 degrees Celsius. Vettel started on the softs and went for a longer first stint than Mercedes, worried by Ferrari's quick getaways, who opted for ultrasofts that were quicker at the start but faded more rapidly. Lining up in fourth place on the grid, Vettel grabbed third from Raikkonen immediately but could not find a way past Bottas who slotted in behind Hamilton as a defense against the red threat. "We were out of position. I think we could have gone with Lewis today with the race pace," said Vettel. "P2 is not really what we wanted this weekend but I think it was the maximum today." ANGRY VERSTAPPEN Raikkonen, without water during the race after Ferrari forgot to connect the bottle, made two stops and agreed third – his fifth successive podium finish – was the best he could have hoped for in the circumstances. "We caught up with Bottas after the first stop but there was no chance to overtake. So our option was to stop again and try again.
