Indian GP: Sauber Friday quotes

Kamui Kobayashi - 13th/16h: "I found it difficult today to find any grip. I can't really say whether this is down to the dust on the circuit, the tyres or the car. Most probably it is a combination of all those factors and we have to find the best way to improve. This goes especially for when we run low fuel, although I didn't do that many laps with a lighter car. I spent a lot of time running on a high fuel load and I think we are doing fine with the heavier car. We have to work now, but also to consider that anyway the grip level of the track will improve."

Esteban Gutierrez - 20th: "It was a great experience to step in for Sergio this morning. For me it was the first time I have been at the wheel of the C31, as I have only done straight line testing so far. Also I didn't know the track before, which made it an even more interesting session. I have worked very closely with the team all season, listening to the radio and attending the engineers' meetings. Today I really enjoyed seeing from the inside of the cockpit what I had only seen from the outside. It was also very interesting to be part of an official Formula One event for the first time. It is obviously different to testing and it is challenging to stay focused. I think the circuit here is amazing, especially with the chain of fast corners. However, my target was to progress during that session and make sure I brought the car home in one piece. Now Sergio will be taking over again but, in case anything should happen, I feel ready to get into the car again."

Giampaolo Dall'Ara, Head of Track Engineering: "Actually today was quite similar to what we experienced at the two recent race weekends, when we were also struggling with our low fuel performance on Friday and were a lot happier with the car's balance on long runs. However, despite the driver change, we still managed to complete our entire programme of evaluating the tyre compounds, which are soft and hard this time, and carrying out set up work under varying fuel loads. We now have to maximise our potential for qualifying."
