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.

2016 Singapore Grand Prix Race Recap | Setting the stage for the final rounds

The Singapore Grand Prix always features a safety car. This year the nation-state got caution out of the way early: seconds after the lights went out, Toro Rosso's Carlos Sainz collided with Force India's Nico Hulkenberg, sending Hulk into the wall minus a wheel and some bodywork. The safety car led the field for three laps, then ducked into the pits so abruptly that a track marshal was still retrieving debris as race leader Nico Rosberg hit the throttle down the front straight. Rosberg avoided the pedestrian on his way to a two-second lead over Daniel Ricciardo in the Red Bull, Lewis Hamilton in the second Mercedes-AMG Petronas, and Ferrari driver Kimi Raikkonen. On Lap 8 of the 61-lap race Mercedes engineers warned Rosberg and Hamilton about brake management. Rosberg had no trouble until the waning laps of the race, his teammate inadvertently the cause. Raikkonen got ahead of Hamilton on Lap 33 while Hamilton nursed his car. Trying to get Hamilton back in front of the Ferrari, Mercedes pitted Hamilton on Lap 46 and also ordered him to turn his engine up. Ferrari debated for a lap about whether to bring Raikkonen in, finally issuing a last-second order to pit. The Finn emerged behind Hamilton, but executing the trick to get Hamilton back into third gave Ricciardo breathing room in second place. Red Bull brought Ricciardo in on Lap 48 for a set of super soft Pirellis. Returning to the track 25 seconds behind Rosberg, Ricciardo cut from one to four seconds out of that gap on every lap. By Lap 59 the Aussie was little more than a second behind the German. Had the race gone three more laps, Ricciardo might have pulled off the upset. This time Rosberg stayed in front to win his third race in a row and his first victory in Singapore, all in his 200th grand prix. Ricciardo and Hamilton completed the podium; Raikkonen claimed fourth. Sebastian Vettel wrangled an incredible fifth place after starting last; the German set the worst time on the grid when his suspension broke in Q1. Max Verstappen, having lost places at the start due to wheelspin again, recovered for sixth. Fernando Alonso made the most of his McLaren with seventh, ahead of Sergio Perez in the lone remaining Force India, a resurgent Daniil Kvyat in the Toro Rosso, and Kevin Magnussen scoring Renault's second points finish of the season. Hamilton has not had a good time of it since the end of the summer break – engine troubles in Belgium, a botched start in Italy, and zero rhythm in Singapore.

2013 Mercedes-Benz SL65 AMG

Make way for the 2013 Mercedes-Benz SL65 AMG, the most wonderfully preposterous car I have ever driven.
There is absolutely no reason why any two-seat roadster should be fitted with a twin-turbocharged 6.0-liter V12 developing 621 horsepower and 738 pound-feet of torque, but I sure am glad that Mercedes-Benz doesn't see things that way.
Drop into the leather-lined cockpit of this $213,145 provocateur, floor the accelerator pedal as I did over and over again, and 60 miles per hour falls in a traction-limited 3.9 seconds. Top speed has been electronically held to 186 mph (this apparently saves Gulfstream jet owners from embarrassment). Forget the SL550 and SL63 AMG, the valets will trip over themselves attending to the tycoon driving this thoroughbred - it's the real deal.
