Race Recap: Singapore Grand Prix is about a safety car and submission

The Singapore Formula One Grand Prix is the Monaco GP of the Orient - a weekend known more for its glamour and time-slot than on-track action, with a temporary circuit that punishes every mistake, usually terminally.
Lewis Hamilton in the Mercedes-AMG Petronas got the best of Free Practice 1, opening the curtain on a possible resurgence of Silver Arrows performance. By the time qualifying was done, though, it was his teammate Nico Rosberg who lined up second on the grid, followed by Romain Grosjean with a beautiful performance in the Lotus, Mark Webber in the Infiniti Red Bull, and Hamilton all the way back in fifth. Behind them were Felipe Massa outqualifying Ferrari teammate Fernando Alonso, Jenson Button getting the McLaren into eighth, Daniel Ricciardo with another good Q3 effort to get into ninth, and the shocker of Esteban Gutiérrez getting his Sauber into the top ten for the first time this year.
At the front of the pack was Sebastian Vettel. Again. But he was only ahead of Rosberg by a single tenth of a second...

Vettel steals victory from Hamilton in Australian Grand Prix

MELBOURNE, March 25 – Sebastian Vettel made full use of the virtual safety car to sneak in front of Lewis Hamilton and hold off the frustrated champion to win Formula One's season-opening Australian Grand Prix on Sunday. The Mercedes engine's infamous 'party mode' that delivered Hamilton a blistering pole lap on Saturday could do little once Ferrari's Vettel nosed ahead when re-entering from pit-lane midway through the race at Albert Park. Pole-sitter Hamilton had appeared set to coast to victory with a clear pace advantage but the race turned on its head with the safety car, which was called after Romain Grosjean's Haas failed and rolled to a stop at turn two. In another bonus for Ferrari, Kimi Raikkonen finished third, fending off Red Bull's Daniel Ricciardo and leaving the unlucky Australian still searching for a first podium in his home race. "We got a bit lucky." Four-times world champion Vettel claimed a 48th overall win and his third in Melbourne following his victories at Albert Park last year and in 2011. "It was needless to say we got a bit lucky with the timing of the safety car," the German, who had started from third place and inherited the lead when Hamilton and Raikkonen had pitted earlier in the race, told reporters. "It's not the easiest track to pass." For Hamilton, the result was a bitter pill to swallow and had echoes of last year's race. Vettel also managed to re-enter in front of him from pit-lane in 2017 before burning away to victory while the pole-sitting Briton was blocked by traffic. Mercedes boss Toto Wolff said his team had miscalculated the margin between the cars during the safety car period. "We thought we had enough margin," he told the BBC. "It must have been a software bug in the system that caused us to get it wrong. We are digging deep now to understand where we had a problem." "I don't understand what's happened." Hamilton, who cockily spoke of "wiping the smile off" Vettel's face with his pole lap on Saturday, battled to keep positive. "Even now I don't understand what's happened," the 33-year-old told reporters. "I did everything I believe I was supposed to do." After the pit-lane setback, Hamilton drove hard to reel in Vettel and battled back after taking a slide at a corner that blew out the lead to nearly three seconds. But he finally waved the white flag in the closing laps to preserve the car for future races.

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.
