Malaysia Friday quotes: Force India

Tonio Liuzzi - 12th: Today was a good opening day of practice for the team. I missed the morning session but we did the most important job of understanding the tyres and following our programme targets. We are quite happy, and although the car suffered a little understeer in the high speed corners, it is responding well and we understand the behaviour of the tyres over the longer runs. It looks like qualifying here will be interesting as the rain started at 4pm but we can deal with the conditions I am sure.

Paul di Resta - 15th: I'm feeling a lot more comfortable and I think that was why I was able to get up to speed relatively quickly. It ran more smoothly today and even though I didn't have any prior experience of the circuit I got into a relatively comfortable zone quite soon. The programme was exactly the same as if Tonio had been in the car, running through baselines and then understanding the tyres. Here the tyres don't last very long with the heat and we missed the peak with them and didn't quite set the optimum time, but I think ultimately you can't pay too much attention to that as it's not always going to be relative to what we are doing and where we are. It's just getting myself in the environment, getting the track time and learning the circuits.

Dominic Harlow, chief race engineer: We didn't encounter any major problems today as we established the relative performance and degradation characteristics of the two tyres available for this race. The high track and air temperatures are, as usual here, dominating the behaviour of the car. Today's sessions have been at the normal times of day, but as we head into the weekend they become later again, and that will be a factor in the decisions we make overnight. We've more work to do, but are looking forward to the challenges of the weekend ahead.
