(CNN) -- Sebastian Vettel and Fernando Alonso will battle it out for the Formula One title at the final race in Brazil after Lewis Hamilton's victory in Texas ensured the German must wait for his third successive championship crown.

Hamilton secured back-to-back victories at the United States Grand Prix in front of a capacity crowd of 135,000, overtaking Red Bull's Vettel on lap 42 of 56 in Austin and relegating the 25-year-old to second in his 100th F1 race.

Alonso kept his title dream alive by finishing third, and gained a controversial place on the grid before the race after teammate Felipe Massa broke the seal on his Ferrari's gearbox and took a five place penalty.

It all points towards a dramatic climax in Sao Paulo, where Vettel will defend a 13-point lead over his Spanish rival, needing to finish fourth or higher to retain the world championship.

The race marked a triumphant return to the United States for Formula One after an absence of five years, with drivers and pundits impressed with the show put on at the newly built Circuit of the Americas.

Though he didn't clinch the drivers' championship crown, Vettel's performance did ensure Red Bull won the constructors' championship for the third time in a row.

But the German, who was heard to be angry on the team radio after Hamilton passed him, blamed Force India backmarker Narain Karthikeyan for slowing him down at a critical moment of the race.

"I wasn't too happy to send a nice big invitation to Lewis when I had to go through Karthikeyan," he said.
