Sebastian Vettel led the race from start to finish to take a dominant win at India, his fourth consecutive victory of the season that takes him 13 points clear of Alonso in the drivers standings.
Vettel and Webber got a clean get away at the start but that's wasn't the case with rest of the field. Jenson Button got a great start and overtook Hamilton at turn 1, however, Hamilton retook 3rd place from Button at turn 3. Then at the back straight Button and Alonso came from either of the sides to overtake the British driver. Things changed again in next few laps as both Alonso and Hamilton overtook Button using DRS. The order was - Vettel, Webber, Alonso, Hamilton and Button.
In the midefield, Michael Schumacher made contact with Toro Rosso's Jean Eric Vergne, Schumacher got a puncture while Vergne had a damaged front wing. Both drivers leaped back to the pits.
Back at the front Vettel extended his lead to Webber, Webber did the same to rest of the field. Also, in the first part of the race Ferrari seemed to have a better pace than McLaren as Alonso was able to maintain a decent gap to the McLaren and Massa in the second Ferrari chasing Jenson Button.
Tyre wear was quite low at the circuit and most drivers were on a single stop strategy. Jenson Button was the first to make his pit stop while leader Vettel waited for lap 33 to make his stop. Hamilton made his stop on lap 31 and got his tyres as well as steering wheel changed in just 3.3 seconds! The pit stop was praised by commentators as well as fans on Twitter.
Kimi Raikkonen made his stop on lap 27 and then went on to overtake Felipe Massa who pitted a lap later. However, Massa later took his position back from the Finn.
Back at the front, Webber's KERS stopped working and Alonso used the opportunity to overtake the Australian and move into 2nd place. Before the race, Alonso said that his target would be to win and if he can't win he must finish in 2nd place. Also, he said that it would be important to overtake the McLaren in the early stages. That makes us think he can see the future!
Vettel also had problems with the car, but he had a 10 second gap over rest of the field and that was enough for him as he took the Chequered flag from 1st place. Alonso finished in 2nd place ahead of Mark Webber who had been trying hard to keep Hamilton at bay for last 10 laps.
Jenson Button went on to finish in 5th place, he lost a lot of time behind Grosjean who made a late pit stop. Nevertheless he set the fastest lap on final lap and prevented Vettel from taking his 2nd consecutive Grand Slam of the season as well as the Indian Grand Prix.
Felipe Massa and Kimi Raikkonen battled till the end and finished in 6th and 7th place respectively ahead of Force India's Nico Hulkenberg. Hulkenberg had a great start from 12th place but then spent a boring race to finish in 8th place at team's home ground. Bruno Senna put on a great move at turn 4 to overtake Rosberg to pick up the final championship point.
India's Narain Karthikeyan finished in 21st place after spending most of the afternoon suffering brake problems. Pedro de la Rosa had a similar problem in sister HRT and on lap 41 his front brakes as he entered the gravel trap and into retirement at turn 3.
Sergio Perez had a accident similar to Michael Schumacher, but with Daniel Ricciardo in which he punctured his tyres. He later retired from the race. Schumacher also retired from the race on lap 55, but since he had completed 90% of the race, he was classified as 22nd. Maldonado also punctured his tyres in an incident with Kobayashi, however he was able to complete the race.
With only 3 races to go, Vettel lead the standings with 240 points, 13 points clear of Fernando Alonso. In constructors, it's an all Red Bull affair, they have 407 points as compared to Ferrari's 316 and McLaren's 306.
