Nico Rosberg and Kazuki Nakajima enjoyed a productive day of free practice at the Circuit de Catalunya in Barcelona today ahead of Sunday's Spanish Grand Prix. The AT&T Williams team-mates both ended the afternoon session inside the top ten, Kazuki in fourth and Nico in seventh place. Under temperate conditions, the pair covered a combined 117 laps of the 4.655km track optimising set-up on their FW30s.

Nico Rosberg: In the morning we tried something that really didn't work out so we had to change back for the afternoon session. The car felt a lot better straight away, but we still have a few balance issues that we need to try to sort out as it doesn't feel so great on the track. Circuit conditions have changed a lot since we tested here last week, so we have to have another look at the set-up before tomorrow.

Kazuki Nakajima: It was a good day for us today. We tried some different set-ups options in both sessions and have found a good direction to take us into qualifying. We will be doing some more work this evening, but we are well prepared for tomorrow.

Sam Michael, Technical Director: It was a good afternoon session after we struggled slightly this morning. We tried something new on Nico's car but it didn't quite work out as we had wanted it to so we reverted back to the original plan for the second session, during which everything was fine. The engineers and drivers worked through the usual programme today, including preparing the two tyres and working out the best one for the race. We experienced no reliability issues at all and we'll now work on our qualifying set-up for tomorrow.
