Vettel wins Indian GP, Alonso second

Red Bull's Sebastian Vettel won the Indian Grand Prix and stretched his Formula One championship lead over Ferrari's Fernando Alonso, who was a battling second, to 13 points with three races remaining.

The victory from pole position was the world champion's fourth in a row - the first time he has done that in a single season - and maintained his dominance in India after winning last year's inaugural race at the hazy Buddh International Circuit from pole.

The 25-year-old German now has 240 points to 227 for Alonso, who started in fifth place, and his surge towards a third title in a row is beginning to look unstoppable despite the Spaniard's best efforts.

His fifth win of the season was the 26th of his career, and the only mistake he made all afternoon was to switch off the engine too early as he came into the pitlane to park under the podium after Indian 2012 Olympic shooting bronze medalist Gagan Narang had waved the checkered flag.

Australian team mate Mark Webber, who was third, gave the winning Red Bull a push with his car to reach the correct spot.

"A very special grand prix. I don't know what it is about this circuit but I really like the flow of it," said Vettel, who has now led every single lap for three successive races - a feat last managed by the late triple champion Ayrton Senna in 1989.

In two years, no other driver has ever led a lap of the Indian circuit either.

"This was another good step for us but there's still a long way to go," said Vettel with his customary caution after performing his familiar raised finger routine.

Webber, who started on the front row, complained of a loss of KERS after 45 of the 60 laps and was passed by Alonso three laps later.

"It is not easy at the moment to fight the Red Bull but we will never give up," said the Spaniard, who passed both McLarens in the early laps, in a podium interview in front of the cheering crowd.

"Well done to Red Bull and Sebastian but we want to be happy and enjoy it in Brazil (the last race). It is not only here. I am sure we will do it."
