Hungary Friday quotes: Force India

Tonio Liuzzi - 18th: As always in Hungary the circuit was quite low grip in the second session, although it looked pretty clean. It was very slippery in places but it should improve for tomorrow as more rubber gets laid down. For now the balance is quite good, particularly on the hard tyre, but we need to understand why we didn't improve on the soft compound. It's going to be a tough weekend for us, but we've done some productive running today and will look at everything overnight to try and find some more time tomorrow.

Paul di Resta: Today was my first outing at the Hungaroring so I necessarily spent a fair bit of time learning the track. It's quite a complicated one to get to grips with and get into a good rhythm, with a lot of corners that flow into each other with no real rest. The average speed is quite slow as well so you're not getting the full effect of the cars as you would at a track like Silverstone. All the same, I really enjoyed being out there. The track was low grip to start with but the grip level slowly improved and we were able to run through all the programme. I wasn't running the blown diffuser so it is difficult to compare directly how I did relative to Adrian, but I am pretty happy with how it went today.

Dominic Harlow, chief race engineer: An interesting day here in Hungary as we learned a great deal about our exhaust blown diffuser with Adrian whilst Tonio concentrated on the tyre evaluations. Initial indications are positive. The circuit was in quite good shape at the start of the day and, as the temperatures increased the grip became a bit harder to find. We can improve the balance a bit more for tomorrow, and things are very tight in our area of the field so it's really a question of examining the data and going forward from there.
