Sebastian Vettel claimed his fourth successive world title and the constructors' trophy for Red Bull with a superlative victory in the Indian Grand Prix on Sunday.
Pole-sitter Vettel pitted early to change his soft tyres but then roared through the field to win 30 seconds ahead of Mercedes's Nico Rosberg, with Lotus driver Romain Grosjean third.
The 26-year-old German becomes the youngest man to win four straight titles, with Juan Manuel Fangio and Michael Schumacher the only other drivers to achieve the feat.
"Unbelievable day," said the jubilant Vettel over the team radio. "We did it! Yes! Yes!"
Vettel celebrated in spectacular fashion by spinning doughnuts in front of the grandstand. He then stood on top of his Red Bull and saluted the crowd before bowing to his car in mock worship.
Despite team-mate Mark Webber's retirement with a mechanical problem, Red Bull also sealed their fourth straight constructors' title in what has become an era of dominance.
