Jenson Button: "In terms of team effort, we did everything right today [Sunday] - our car just wasn't quite quick enough to actually win. I got a good start, made up places on the first lap and then settled down to keep Mark [Webber] behind me for five or six laps.
"Eventually, I think we 'broke' his rear tyres, which enabled me to establish a gap. Then I could set about Seb [Vettel] - but it was very difficult to close him down. At the final stop, it was a risk going to the harder tyre earlier than Seb, but we had to give it a go and it worked pretty well as I was able to close him down by a further three seconds. My car felt really good: before Seb could find his rhythm on the Prime, I was able to get the gap down to 2.8 seconds, but it wasn't quite enough.
"Still, this was a very good result for us - and I think we delivered the maximum possible. I loved the whole experience this weekend. And I think every driver will be excited about coming back here because it's such a phenomenal circuit; fast and flowing with a bit of everything. It gets a big tick from me.
"The Indian people have really welcomed us to their country; I've never seen so many people smiling before. And the crowd has been wonderful. I hope that Formula 1 grows in India in the future and that we get an even bigger crowd here next year."
Lewis Hamilton: "The contact with Felipe [Massa] was just one of those things. I really didn't feel like I was at fault - it was a racing incident. On the grid, just before the one minute's silence, he and I were standing next to each other and I put my arm around him and told him: 'Have a great race today [Sunday].' I've still got great respect for him.
"During the race, it felt like there was a vibration in the car through the right-handers: it felt like the floor was scraping on the ground, in fact. I was pushing as hard as I could, but couldn't find the performance, so we'll have to look into that. It's been an eventful year, but there are more races ahead and I'll try to score as many world championship points as possible in both of them. Jenson did a great job today [Sunday], so clearly we were quick enough. I just need to try to pick up on that for the next race."
Narain Karthikeyan: "I had a great grand prix and I really enjoyed myself, it was an amazing experience. To finish 17th in my home grand prix is the best I could have wished for with the car we have and beating my teammate and one Lotus on the way makes it all the more satisfying. It's a shame I faced the penalty and, perhaps, we could have had a much better race without it.
"But I made a good start and then suffered some damage to the front wing but afterwards I picked up a good rhythm and was able to complete a good race. It's an awesome feeling to have completed the first ever Indian Grand Prix and to have been competitive with our main rivals which proved a lot of points."
Daniel Ricciardo: "The first laps weren't great but then I managed to pass a few people. Some laps later I got past Narain and set a good rhythm; I was happy with the first stint as everything was going well, the balance was good and the tyres were performing well.
"In the second stint I felt a strange feeling in the front of the car after a couple of laps, the car was moving quite a bit from left to right, I still don't know the reason for this but it might have been a puncture. It's a shame because as a cause we had to do an extra pit stop and lost quite a bit of time with that. In the third stint, once we found our pace we were quite competitive. It ruined the rhythm of our race but hopefully we can avoid it from happening next time."
Rubens Barrichello: "I lost my nose going into the first corner at the start so I had to come in for an unscheduled pitstop. That ruined my race from the outset because I came out of the pits so far behind. After that, we had to change our strategy to a one stop to avoid losing more time. We dragged it back a little bit, but not enough to score points. It's a shame because our times were strong and tyre degradation was ok so we could have done better."
Pastor Maldonado: "We had a problem with the gearbox today [Sunday], but we don't know the exact cause yet so we need to have a look into it. My pace was looking good before that and the tyres were working well. Just bad luck. We need to look forward to the last two races now."
