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.

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 previews longer, more lavish S-Class ahead of debut

In some international markets, Mercedes-Benz's new 2021 S-Class will get Level 3 semi-autonomous technology, but chauffeur-driven buyers already enjoy full autonomy. It's for these individuals that Mercedes-Maybach, the firm's extra-luxury division, stretched the sedan's wheelbase and gave it an interior worthy of a private jet. Maybach said it developed its variant of the 2021 S-Class specifically for buyers with a chauffeur. It added seven inches to the sedan's wheelbase, and the additional sheet metal benefits those riding in the back. Standard executive rear seats give passengers a comfortable place to work or rest while they're being driven, and the list of new features added to the sedan include massaging calf rests as well as heating for the neck and shoulders. Although we haven't seen Maybach's S-Class yet, a preview image shows the optional two-tone paint — one of the company's hallmarks — and a chromed Maybach emblem. Up front, it will receive a specific grille with vertical slats instead of the horizontal ones worn by the standard S-Class. An additional serving of chrome-look trim will almost certainly further set the Maybach apart, but it will retain its predecessor's relatively subtle design. Specifications won't be announced until the model's unveiling. Mercedes-Benz confirmed it's phasing out V12s, though the big engine could return for one final round under the hood of the S-Class. Alternatively, Maybach may have chosen to surf the downsizing wave still sweeping across the industry by selecting a 4.0-liter V8. Mercedes-Maybach will introduce the 2021 S-Class online on November 19 at 2 p.m. Stuttgart time, which is 8 a.m. in New York City and 5 a.m. in Los Angeles. Deliveries are scheduled to start during the first half of 2021. When it lands, the sedan will join Maybach's variant of the GLS in showrooms across the United States. Related Video:
