KERS cooling affected Williams' Saturday schedule

Saturday was Rubens Barrichello's turn to hit the track in the FW33 as he took over from Pastor Maldonado. The Brazilian soon encountered problems with his KERS unit but fortunately managed to get some long runs completed in the afternoon after the problems were solved.

Sam Michael, Technical Director: After a couple of setup runs this morning we had a problem with the KERS onboard cooling system. We had to stop and remove some components to ensure the car was safe, and that cost us three hours. In the afternoon we made good progress with the aero setup of the FW33 on long runs, with Rubens generating some good data for the wind tunnel.

    Chassis / engine: FW33-01 / CA320
    Objectives: Setup work and long runs
