Kimi Raikkonen won a crash-filled Abu Dhabi Grand Prix on Sunday for his first victory since returning to Formula One this year, a result that throws open the drivers' championship with two races remaining.
Raikkonen, the 2007 champion who returned to F1 after rally driving for a year, overtook Red Bull's Mark Webber at the start to move into second. He took the lead on the 20th lap when McLaren's Lewis Hamilton retired because of a fuel pressure problem and then avoided the half-dozen crashes and collisions that twice brought out the safety car.
Raikkonen held off Ferari's Fernando Alonso, who finished second. Two-time defending champion Sebastian Vettel clawed back from last to finish third, his lead over Alonso cut to 10 points.
McLaren's Jenson Button finished fourth followed by Williams' Pastor Maldonado.
Vettel was penalized for fuel irregularities after qualifying, forcing him to start from the pits. He tops the drivers' championship with 255 points, followed by Alonso at 245 and Raikkonen at 198.
Red Bull leads the constructors' championship with 422 points, followed by Ferrari on 340 and McLaren 318.
"I'm very happy for the team and myself but mainly for the team," said Raikkonen, who last won a race in 2009 with Ferrari at the Belgian GP and now has 19 wins. "It's been a hard season for the team. Hopefully, this gives us more belief, not just for those are doing the work but those who run the team."
Alonso, who struggled for pace across the weekend, said he is thrilled to have repeated his second place from the Indian GP after also starting down the grid in that race.
"I'm very happy. We were not so competitive this weekend and we started sixth with Sebastian's penalty," Alonso said. "We had to fight from the first lap, some good overtaking. Then, we had a very good strategy that gave us the ability to fight until the end of for the victory. In the last couple of laps, Kimi was little slow and we attacked. Second was the maximum. We will keep fighting until the end."
Vettel said he always believed he would end up on the podium.
"I said to myself either we go full attack or nothing," Vettel said. "That is what we did. We had a fantastic race."
On a circuit some drivers have called boring, the incidents started on the opening lap. Force India's Nico Hulkenberg collided with Williams' Bruno Senna and exited the race. Eight laps later, Mercedes' Nico Ros-berg ran into the back of Narain Karthikeyan and went flying over the HRT car to crash into a wall.
Starting from the back of the field, Vettel was in the middle of many of the mishaps during the race and responsible for a few of them.
Moving quickly through the pack, he damaged his wing when he clipped Senna. He then misjudged the pace of Daniel Ricciardo's car in front and ran over a board - prompting him to curse Ricciardo over his team radio and requiring a visit to the pits to get a new wing, sending him down to 21st.
Vettel returned and again aggressively started overtaking, going off the track to pass Romain Grosjean and then colliding with Felipe Massa, causing the Ferrari driver's car to spin.
Despite all that, he moved up to fourth and then overtook Button with three laps remaining.
"It was nice fight with Jenson. He was difficult to pass. With him, I was really struggling. I just squeezed my way past," Vettel said.
Hamilton's earlier departure ends his bid for a second title as it did for Vettel's teammate, Mark Webber, who pitted at one point to allow the German to move ahead of him into fourth.
