Singapore: Sebastian Vettel won the Singapore Grand Prix on Sunday but the Red Bull driver will have to wait a little longer to clinch his second Formula One world championship.
The German led throughout from pole position to finish 1.7 seconds ahead of fast-finishing McLaren driver Jenson Button, with Red Bull's Mark Webber third.
Vettel leads the drivers' championship by 124 points with five races left and is virtually certain to take back-to-back titles. To prevent that happening, second-placed Button would need to win every race while Vettel fails to gain any points. Vettel has 309 points with Button on 185.
"It was a fantastic race from start to finish," Vettel said. "In the heat we kept our heads cool and it was a perfect day in the office.
"It means a lot to me because I really like this track and it's one of the hardest challenges we face each year, so it's nice to come out of that as a winner."
Ferrari's Fernando Alonso finished fourth and McLaren's Lewis Hamilton was fifth after another incident-filled race for the Briton, who had to serve a pit drive-through penalty for crashing into Ferrari's Felipe Massa on lap 12.
The incident prompted a furious post-race reaction from Massa, who said the McLaren driver "doesn't learn anything."
"I tried to talk to him but he doesn't listen," Massa said.
Vettel looked untroubled until the closing stages as Button cut the gap by six seconds in just five laps to get within 3.7 seconds with three laps to go, but the Briton was hampered on his chase by backmarkers.
"I was in control," Vettel said. "We were in a comfortable position for most of the race which is not easy around here."
Button was unimpressed by the lack of awareness of some of the backmarkers, being stuck behind Sauber's Kamui Kobayashi for more than a lap and then being impeded at a key moment by the two Williams drivers squabbling over 11th place.
"It's something we need to resolve for the future," Button said. "None of us is stupid, we know if we are being lapped or not."
Mercedes' Michael Schumacher crashed out of the race in spectacular style half-way through, running into the rear of Sergio Perez's Sauber and launching his car through the air into a barrier. The collision was subject to a post-race stewards' investigation but the seven-time world champion described it as a standard racing incident.
"Basically he just lifted off too early and I couldn't anticipate it," Schumacher said. "I was about to try and go on the inside as he was a lot slower than myself. Unfortunately, we had a misunderstanding. It was a shame."
Force India rookie Paul di Resta was sixth in his best finish.
Mercedes' Nico Rosberg was seventh, ahead of Force India's Adrian Sutil.
Massa recovered from the Hamilton crash - which caused a rear tyre puncture - to finish ninth and Sauber's Sergio Perez was 10th.
Vettel made a faultless start and powered away from the field in extraordinary style. He led by 2.5 seconds after one lap and the gap reached ten seconds inside eight laps.
Button managed to stablize the gap, and the emergence of the safety car due to Schumacher's accident compacted the field. Button's chances of immediately challenging the leader were foiled as he was stuck behind the backmarker Jarno Trulli at the restart, and one lap after the safety car had gone in, Vettel's gap grew to 8.9 seconds.
The German claimed he was concentrating throughout the race on the immediate contest rather than calculating whether he had clinched the championship. Now, with only one point needed in five races, he won't need much mathematical prowess to figure it out.
"Crossing the line, I didn't know if it was enough or not," Vettel said. "For the next race, I am smart enough to work it out myself."
"With the races we have had so far, it (winning the title) should not be a problem."
