Jenson Button switched to chassis 007-02 on Friday at Valencia running a fresh engine alongside the latest specification gearbox. He ran through some chassis set-up work to complete 48 laps in the morning session.

Enrique Bernoldi, however, had a frustrating morning in chassis 007-01 as his engine failed after 15 laps stopping the car out on the circuit. With the engine changed, he went out to complete three runs before lunch, bringing his total for the morning to 30 laps.

Jenson spent the afternoon continuing his chassis set-up work alongside a tyre evaluation. He completed a total of 122 laps today setting the second fastest time - a 1m 10.601s. Enrique also ran through some tyre work and he completed 72 laps for the day.

Meanwhile, in the Young Driver Programme, Alan van der Merwe completed his final session in the 006 car. He ran through a short chassis test, completing seven runs for a total of 52 laps. Adam Carroll ran in the afternoon session, completing 26 laps in total and setting a respectable time of a 1m 12.585s.
