Sebastian Vettel dominated the race
Sebastian Vettel dominated the Indian Grand Prix to take a fourth win in a row and extend his championship lead over Ferrari's Fernando Alonso.
The Red Bull driver is 13 points clear of the Spaniard, who was second ahead of Vettel's team-mate Mark Webber, reports the BBC.
The Australian was holding off Alonso when he suffered a Kers power-boost problem and the Ferrari swept by.
Lewis Hamilton closed on Webber but had to settle for fourth ahead of McLaren team-mate Jenson Button.
Vettel is a strong favourite for the title, with Red Bull in imperious form and 75 points available in the remaining races.
The German equalled the legendary Ayrton Senna's record of leading every lap of a race for three consecutive grands prix, set for McLaren in 1989. And Vettel won in India for the second straight year after dominating here in 2011.
"It has been an incredible two years for us here to get pole on Saturday and win the race on Sunday," said Vettel. "It's a very special grand prix, I really like the flow of this circuit. Sector one is a bit slow with long straights, but sector two and three is very nice."
Ferrari's Felipe Massa took sixth, closely followed throughout the race by Lotus's Kimi Raikkonen, who is now almost completely out of the title race, 67 points behind Vettel in third place overall.
Webber, in fourth place in the championship and 70 points adrift of Vettel, retains a mathematical chance but the championship battle is now effectively a fight between Vettel and Alonso.
On current form, it is hard to see how the Spaniard has any realistic chance of closing the gap and preventing Vettel and Red Bull making it three championships in a row.
"It's not easy at the moment to fight the Red Bull but we will never give up," Alonso said. "We lost points but this was more or less the plan this weekend; we were not fast enough to compete with them. We lost the minimum points and better races will come."
