Heikki Kovalainen: "That was a reasonable session for me - I had a DRS issue that definitely cost me some time but I think the balance was pretty good and we got through some decent setup work so I think we'll be ok tomorrow."

Jarno Trulli: "I'm pleased in general with today. It's been a positive, trouble free day and we managed to run through a number of options that give us a good direction for tomorrow and the race. We have made an adjustment to the power steering and that's definitely improved things in the cockpit for me but there's more to come from that and the whole car so I think we can go into tomorrow in good shape."

Karun Chandhok: "The wet weather meant we limited the morning runplan but despite that it was good to get back out on track. I didn't get a chance to push but I'm enjoying working with the team and the more time I spend with everyone the more I can see how far this team can go. There's a great spirit across the whole garage, and back in the factory, and with the constant progression towards the midfield this is a great place to be working in."

Thierry Salvi, Renault Sport F1 Support Leader: "We didn't manage to do much running in P1 this morning due to the weather so we had to work a lot harder during P2 this afternoon, especially with specific engine mapping. I hope we will have good feedback from the drivers and can take another step forwards on strategy. I think there is more to come from the whole package tomorrow so this was a pretty good start to the weekend."

Mike Gascoyne, Chief Technical Officer: "A pretty good day. Obviously we had limited running this morning in the wet conditions as we wanted to save tyres in case we have to use wets in the race. Unfortunately that limited the running Karun and Jarno could do but this afternoon we completed the whole program without any real problems with the performance levels we showed I think we are looking at having a pretty good weekend."
