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.

Rain prolongs the Championship battle | 2016 Brazilian Grand Prix recap

Rain and an old-school circuit are the antidotes to Formula 1's constricting technical regulations and Tilke tracks. At Brazil's Autodromo Jose Carlos Pace – otherwise known as Interlagos – rain Saturday night and on race day washed away everyone's careful plans, except for those of the man at the front of the pack. Lewis Hamilton put his Mercedes-AMG Petronas ahead of the field throughout the weekend. On Sunday, a storm-delayed start behind the Safety Car assured Hamilton of a clean path to the lead and a clear track. The Briton didn't waste it, pulling out a gap on teammate Nico Rosberg behind, and Rosberg appeared to have no interest in going hard after Hamilton. Safety Cars and red flags kept resetting the gap to zero, though. After the Mercedes-AMG GT S led the first seven laps, it emerged again on Lap 13 for another six laps when Marcus Ericsson crashed his Sauber. Seconds after racing resumed, Kimi Raikkonen aquaplaned his Ferrari into the wall on the front straight. That caused the first red flag, leading to another eight-lap Safety Car interval, then a second red flag stoppage due to conditions on Lap 28, then three more Safety Car laps, and then, finally, racing again. Hamilton never surrendered his lead. The Briton changed tires once during a stoppage, and drove fast enough to cover the full race distance despite the intermissions. Afterward, he said "it was a very easy race." Rosberg had it harder, defending against the preternatural Max Verstappen in third. Barring misfortune it's already clear the Red Bull pilot has at least one Driver's Championship in his career future. In Brazil the young Dutchman drove like he's worthy of the hardware right now. After Verstappen passed Rosberg for second on Lap 34, the Red Bull driver pitted for intermediate tires on Lap 44 – a huge gamble in the conditions – coming back out in fifth. That tire wager failed, giving Rosberg a safe position in second when Verstappen had to pit for extreme wets on Lap 54 of 71. The teenager re-emerged in 16th. Over the race's final 17 laps Verstappen passed 13 drivers at six different places on track. He ran it close-but-clean a couple of times, especially when getting around Sebastian Vettel and Sergio Perez, but he was simply untouchable. Not only did the Dutchman score an amazing third place, he put in what could be the drive of the season.

New details emerge on forthcoming Mercedes-Benz SLC

Last we heard, the Mercedes-Benz SLC had been put on indefinite hold, but now Car Magazine is reporting that the Porsche 911-fighting "Baby SLS" coupe could be on sale by 2015. Riding on a modified SLS AMG chassis, the smaller and lighter SLC could be priced in the sub-$100,000 price bracket.
We'd already heard that the new car would feature conventional doors (instead of SLS-like gullwing doors), but this report focuses on some of the possible powertrains Mercedes-Benz is likely to use. At launch, the SLC could offer a pair of V8-powered models - a 485-horsepower SLC and a 585-hp SLC S - both being powered by a 4.0-liter twin-turbo V8. About a year after launch, a new V6 model could emerge giving the SLC an estimated 333 horsepower and its lowest price point.
It also sounds like the car's name hasn't been completely finalized as some people within Mercedes are favoring a return of the SLR name.
