Jarno Trulli: "That was a trouble free Friday afternoon for me but honestly I'm not all that happy with the balance of the car at the moment. There's quite a lot of understeer on turn-in and through the exit of the corners and we need to work on dialling that out to find more speed. There's definitely more to come and we've shown all season we can take good steps forward from Friday to Saturday, so I think we'll be ok tomorrow."

Karun Chandhok: "I'm pretty pleased with the performance this morning. The car felt OK from the first laps and it was good to get some more time under my belt in the cockpit. Friday mornings are always pretty limited running, particularly when the track's got that light covering of dust on it, but today I was focusing on some aero evaluation and we got through that program so I think I did ok today."

Heikki Kovalainen: "That wasn't too bad but we can definitely improve. This morning's session was brought to an early end with a sensor issue on the gearbox and I was given the instruction to pull over when the engine temperatures started rising. This afternoon we worked on both sets of tyres and I think the softs are ok but we weren't really able to get the best out the mediums which gave us some areas to work on tonight on improving overall grip."

Thierry Salvi, Renault Sport F1 Support Leader: "This morning we worked with Karun on engine mapping and he did a good job for us collecting a lot of data we can use on both race cars this weekend. The chassis he was in, which reverted to Jarno for the afternoon session, completed decent mileage throughout both sessions, but this afternoon we struggled a bit with Jarno in the car, and we need to spend some time this evening to make sure we can progress for FP3 and qualifying."

Mike Gascoyne, Chief Technical Officer: "That was a bit of a difficult Friday for us. It started well this morning with Karun doing a good job running through an aero evaluation program and it was good for him to have a full session in the dry. For the race drivers, the main problem today was getting heat into the harder tyres and I think we may find that improves with increasing the downforce levels tomorrow. Both Jarno and Heikki were reporting that they could not find enough grip and as that is linked to both tyre performance and the downforce package the goal is to solve that for tomorrow and unlock the speed we know is in the car for qualifying."

Riad Asmat, Group CEO: "That was not one of our best Fridays. Despite completing a pretty decent number of laps we struggled to find grip on both cars all day so the main challenge now is for the engineers to work through the data that we have accumulated and improve our speed tomorrow. We know we can increase performance levels in all areas for FP3, qualifying and the race, and that is the focus now for the remaining sessions."
