Nick Heidfeld drove the F1.07B. He had a limited programme and concentrated on systems settings. He did a lot of valuable work that can be transferred to the new car. Robert Kubica was at the wheel of the F1.08 working on the mechanical and aerodynamic set-up of the car. In addition, he did numerous systems checks and tested different suspension parts. Both cars ran reliably all day.
What comes next: Tomorrow, Robert Kubica will continue driving the F1.08 while Nick Heidfeld will again be at the wheel of the F1.07B.
