Indian driver Narain Karthikeyan says it was an emotional Friday practice for the Indian GP.

Karthikeyan: The first lap was very special; I felt so many emotions driving in India. I just couldn't believe it and there were so many things running through my head. In the first practice we were just trying to get into the swing of things and the second one went much better and we have a lot of things to try for tomorrow. Overall it was a good session for me, considering I haven't driven a full race distance since July, so the body needs to wake up a bit. The track evolved a lot and so times were improving too. We have a few things to try ahead of tomorrow so I'm quite excited to see how qualifying goes.
