Heikki Kovalainen - car 20, chassis CT01-#03: "A much better Friday than we've had for a while. Right from the installation lap the car balance felt better and we're clearly more competitive here than we have been anywhere since Valencia.

It's difficult to understand where the improvement has come from - the cars are in a very different configuration than Spa, Hungary, Hockenheim or Silverstone but that doesn't explain the difference in the feeling and the performance.

We need to get a better understanding of why we're better here and then make sure we can translate that into being more competitive at every type of track.

"It's a positive feeling for everybody. Spa was not acceptable, that's clear, and when we don't really understand why we weren't competitive it's more difficult to sort out, but coming here we're back to the base level of performance we should have and now we need to build on that."

Vitaly Petrov - car 21, chassis CT01-#02: "I think we are moving in the right direction and it's been a much better day for us than we had last week, or for a few races now. We ran both cars in different aero configurations so we could generate as much data as possible and the laptimes look pretty good.

That gives us a lot to work on tonight, to prepare for quali and the race and it's good to see us getting back to where we want to be.

"After the ups and downs we've seen so far this year I don't want to make any predictions about where we'll end up on Sunday, or in Singapore or any of the races to come, but I think that if we carry on like we have today we'll be looking much better. That's a good feeling, for me and the team, and hopefully the similar weather conditions we'll have on track tomorrow will suit us so we can have another positive day."
