Sebastian Vettel cruised to victory at the Brazilian Grand Prix, but the Formula One title is still up in the air ahead of next weekend's Abu Dhabi season finale
Vettel's Red Bull teammate Mark Webber was second, championship leader Fernando Alonso of Ferrari third, and Lewis Hamilton of McLaren fourth in Brazil.
Alonso was the only driver who could have won the championship Sunday, but his third-place finish was not enough. Alonso remains atop the standings with 246 points, while Webber has 238 and Vettel 231. Hamilton has 222 points and remains in contention.
Taking the top two places ensured Red Bull its first constructors' championship.
Defending champion Jenson Button of McLaren, who was nearly robbed by armed men outside the track the night before the race, finished fifth to end his shot at winning two titles in a row.
Felipe Massa, a two-time winner in front of his home crowd in Brazil, had problems on the pit lane and fell out of contention early in the race, finishing 15th.
Rubens Barrichello of Williams made contact with Sebastien Buemi of Toro Rosso midway through the race and fell to the back with a punctured tyre, finishing 14th.
