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.

Race recap: 2015 Singapore Grand Prix full of odd sideshows

What greeted the Formula One teams in Singapore? Confusion. The haze was so thick that observers wondered if the race would be held at all. Then practices began, and Mercedes-AMG Petronas driver Nico Rosberg took the first one, but the team fell away after that. Mercedes said it couldn't get the tires turned on, but no one believed the Silver Arrows was in genuine trouble. Then qualifying set the confusion in stone. Ferrari driver Sebastian Vettel laid down the best time in Q3, taking the team's first pole position since Germany in 2012. Daniel Ricciardo got his Infiniti Red Bull Racing into second, about one tenth behind Vettel. (That may make the team feel better after Ricciardo publicly asked for a better engine than the current Renault unit, and team advisor Helmut Marko said the outfit will quit F1 at the end of this year if it can't get a stronger powerplant for 2016.) Kimi Raikkonen put the second Ferrari in third, Daniil Kvyat put the second Red Bull in fourth. And only then came the Meredes'. Lewis Hamilton's best got him fifth, the Brit saying, "We don't really know what we have got wrong. For some reason the tires are not working on the car. We do the warm-up the same as everyone else and then you see someone one second up the road." For added emphasis on the reversal of fortune, his time was 1.6 seconds behind Vettel's. Teammate Rosberg is next to him in sixth, a further half a second back. Williams is still a hurting a bit on slow tracks, so Valtteri Bottas could only get into seventh ahead of Max Verstappen in the Toro Rosso and teammate Felipe Massa in ninth. When the red lights went out, the 2015 Singapore Grand Prix would get both less interesting and more interesting all the way to the final lap. The men up front got good getaways, and the order into Turn 1 was Vettel, Ricciardo, and Raikkonen. The race finished with those three in that order, never having conceded position. Vettel's Ferrari enjoyed the track so much that he laid a second per lap into Ricciardo for the first five, then relaxed. He'd let the gap come down later in the race a couple of times, but any time he wanted to see what his mirrors looked like without anyone in them he'd take off again. Rosberg took fourth position after holding down sixth for the first stint. It looked like he'd have an even worse day - for a Mercedes driver - when he had problems getting his car started and onto the grid before the race.

Daimler boss says fuel cell vehicles will be disappointing for at least 10 years

Daimler AG CEO Dieter Zetsche is pretty confident about the imminence of self-driving cars. Hydrogen fuel-cell vehicles? Not so much. He didn't even get into the possibility of self-driving fuel-cell vehicles, but we're okay taking future technologies one at a time. Zetsche, in an interview from the Detroit Auto Show last week, said the automotive industry is about a decade away from avoiding disappointing experiences with production fuel-cell vehicles, In Auto News says. Zetsche was quick to note that the Mercedes-Benz parent entered into a fuel-cell partnership with Ford and Nissan early last year in an effort to split costs and speed things along, with the expectation that the group would develop something together by 2017, but even that won't be able to smooth things out fully. Toyota and Hyundai have said they'd have their own production vehicles on the road sooner than that. Multi-corporation-partnerships notwithstanding, Zetsche bemoaned the high costs, lack of vehicle volume and minimal refueling infrastructure as the proverbial roadblocks to more rapid development and adoption of fuel-cell vehicles. As it is, the US has just 10 publicly accessible hydrogen refueling stations, eight of which are in Southern California, according to the US Department of Energy. As for autonomous automobiles, Zetsche was more upbeat. Daimler already has what it calls the "Distronic" cruise control system that includes an automatic braking feature and has successfully driven a car 60 miles with "with relatively modest adjustments to the existing onboard technology."
