The AT&T Williams team had a productive three hours of practice time on track today, providing a good start to preparations for Sunday's Bahrain Grand Prix. The team has benefited from a trouble-free day which has enabled the engineers and drivers to investigate some alternative set-up options early in the weekend.

Nico Rosberg: I am happier with the car here compared to the last race in Malaysia and I think we are back to normal now, which is encouraging. The circuit surface suits our car better, which in turn made it much more enjoyable to drive. Over the two sessions we made some very big set-up changes and I think we've gone into the right direction. It's getting very close with a lot of people in the midfield, but I think we have a good chance to do well this weekend. It was also productive to be reliable today which meant plenty of track time.

Kazuki Nakajima: Today we didn't have any problems, so we could use all of the practice time which was great. Initially in the morning session, I struggled a bit, but in the afternoon, we made a big set-up change which was very positive. We have a bit more work to do tomorrow, but it is a good start.

Sam Michael, Technical Director: We had a good first day's practice with no interruptions from a reliability point of view, and that enabled us to get through a full programme of set-up changes, tyre work and checking cooling and brakes. We will now work on qualifying performance for tomorrow.
