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.

Mercedes-Maybach Pullman is the luxury car for the discerning dictator

For decades, Mercedes-Benz and Mercedes-Maybach cars have been the ride of choice for leaders across the globe, presidents, ambassadors, dictators and despots alike. The Pullman model — a long-wheelbase six-seat variant — has been particularly popular with this select clientele. This week, the German automaker announced the latest version of the car, the Mercedes-Maybach Pullman S650. Essentially, this is a stretched version of the V12-powered Maybach with two rear-facing seats just behind the front row. Mercedes is calling this vis-a-vis seating. There's also a partitioning glass between the front seats and the rear cabin. This is of course to help prevent the chauffeur from learning and spilling any state secrets or plans for plans for secret moon bases. New for this model is a front-facing camera for rear-seat passengers. This allows occupants to watch for any oncoming obstacles, barricades or road blocks. Visually, there's no mistaking the Pullman for another Maybach or really anything else on the road. The car is 21.3-feet long, 4.5-feet longer than the standard Maybach or roughly the size of two and a half Smart Fortwo placed bumper-to-bumper. The requisite 20-inch 10-hole wheels are present and the standard pinstripe Maybach grille has been updated with a slightly new design. The car only comes in S650 trim, meaning it's powered by a 630 horsepower 6.0-liter twin-turbo V12. As expected, the Mercedes-Maybach Pullman isn't cheap. Orders have started, but be prepared to shell out at least $615,000 before adding any custom touches.

2015 Malaysian F1 GP springs hot, humid surprises [spoilers]

In the two weeks since Australia both Mercedes and Ferrari spoke of the improved performance from their respective cars. In Malaysia, Ferrari showed it. Lewis Hamilton still put his Mercedes-AMG Petronas on pole position, but Sebastian Vettel got within two whiskers of the Brit, lining up second just 0.074 behind. Afterward, Vettel said Ferrari could win the race if everything went well. But in qualifying we didn't know how much of Ferrari's performance was truly down to the car and how much was down to the wet weather that struck near the beginning of Q2. The rain didn't hamper Nico Rosberg's run – the German said "I just didn't drive good enough" – and he took third spot in the second Mercedes-AMG Petronas. Showing what the Infiniti Red Bull Racing chassis can do when the power unit is working properly, teammates Daniel Ricciardo and Daniil Kvyat grabbed fourth and fifth. Whippersnapper Max Verstappen, in his second race, qualified in sixth with an excellent drive through the rain; just 0.030 behind Kvyat, he said he could have got fifth if he hadn't had a running problem with his brakes. Williams head of vehicle performance Rob Smedley said he wouldn't complain about Mercedes' advantage, but Felipe Massa has spent the whole season so far banging the alarm about Ferrari's pace. He says Williams has lost its straight-line advantage, part of the reason the first Grove car is back in seventh, while Valtteri Bottas is in eighth. Between them was Romain Grosjean in the Lotus, but he got dropped two positions for a pit-lane infraction in Q2, so he'll be tenth. Ahead of him is Marcus Ericsson in the Sauber, who would lead the charge to turn in another surprise for the Swiss team. But the real surprise came from the Scuderia Ferrari, who, on a bright, sunny day proved that they don't need to add water for race-winning pace. While Hamilton got made usual awesome start at the lights, Vettel channeled that other famous German Ferrari driver and immediately cut across the track to intimidate Rosberg, maintaining his second place position into the first turn. Arguably the race-winning move came three laps later at that same turn, when Ericsson plunged in too fast and swapped ends, beaching the rear of his Sauber in the gravel trap. The safety car came out when the recovery truck emerged to retrieve the Sauber, and nearly all of the front-runners took to the pits to swap out of the medium tires. Vettel, however, didn't.
