Sebastian Vettel led Mark Webber to a Red Bull one-two in the Brazilian Grand Prix to take the world title fight to the final race of the season.
Ferrari's Fernando Alonso took third place to retain the championship lead from Webber and Vettel.
Red Bull's formation finish ensured they clinched the constructors' championship for the first time.
Lewis Hamilton was fourth and retains a slim title chance while Jenson Button's fifth means he cannot retain his crown.
Alonso can afford to finish second in Abu Dhabi and still take the title if Webber wins, or fourth if Vettel does.
Germany's Vettel said: "It was an incredible day, not easy to start with. I was on the dirty side but got a good start and I saw Nico [Hulkenberg] had wheelspin.
"He didn't give me a lot of room but then it was OK. I could cruise into the distance and control the pace. It's an incredible effort from the team. It has not been an easy season, but this was the perfect answer after what happened in Korea".
Looking ahead to next weekend, he added: "I don't wish anything bad to happen to [Alonso], but it would be nice if we see some nice Ferrari smoke. No, joking apart, we try to win the race and we see where he is".
Alonso admitted: "We lost too much ground in the first laps of the race trying to overtake Hamilton and Hulkenberg. Those 10-12 seconds were impossible to catch. We were very close on race pace.
"We had a little chance when the safety car came out but we found ourselves in the wrong position again with six or seven cars between Mark and us. In terms of points we are extremely happy".
