Sebastian Vettel won the grand prix of India today to strengthen his grip on securing a third successive world title.
Vettel led the Indian Grand Prix from lights to chequered flag to open up a 13-point lead over Fernando Alonso with three races remaining as the Ferrari star was forced to settle for second, albeit his best finish since a win in Germany in July.
Not since Jenson Button in 2009 has a driver chalked up four wins in a row, with Vettel's run to the championship finish line seemingly perfectly timed.
Alonso profited from a Kers failure of the car of Vettel's Red Bull team-make Mark Webber to slip into second place.
Webber managed to hold off McLaren's Lewis Hamilton to third while Jenson Button was fifth in the sister McLaren.
