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.

Mercedes calls CLA 'best launch in 20 years' as it warns dealers of tight supplies

It's still in the early going, but it's looking more and more like the 2014 Mercedes-Benz CLA is a verifiable home run for the German brand. According to a new report from Bloomberg, the new small car isn't just widening the sales gap between Mercedes and BMW, it's attracting a new, younger breed of customers into the brand's showrooms. But that early success is straining supplies of the turbocharged four-door.
Dealers have been warned that the first half of 2014 will see limited supplies for CLA, with a letter to dealers indicating that "tight inventories and low days supply" will exist from February through June, despite the car's Kecskemét, Hungary plant running at full tilt.
"This is our best launch in 20 years," said Steve Cannon, the US boss for Mercedes. "The CLA has been a phenomenal success right out of the gate." The numbers certainly support that. We reported in early October that Mercedes moved 2,300 CLAs in its first week on sale, and now Bloomberg is saying CLA sales were almost singlehandedly responsible for Benz's November sales gains. Mercedes' annual sales are up 14 percent through the November, and it's enjoying a healthy 7,600-car lead over BMW.
