On a hot and sunny day the BMW WilliamsF1 team would return to testing after their enforced break. The team was at the famous Monza circuit preparing for the next race in the calendar the Italian Grand Prix, 4th September. The test is for three days with Mark Webber and Test driver Nico Rosberg sharing the testing duties.

Both drivers would focus on preparing the FW27 for the Italian Grand Prix. Mark would complete forty five laps, with a best time of 1m:22.491.Nico would complete fifty two laps on his way to a best time of 1m:22.890. The team would also take the opportunity to further investigate the reason behind the tyre failures that took place during the Turkish Grand Prix.

WilliamsF1 Technical Director Sam Michael commented on the days testing by saying: "Following the tyre incidents in Istanbul, the team spent the first day of the Monza test analysing the potential cause of the problem. Williams and Michelin have investigated the tyre running parameters, such as pressure & camber, and concluded that the tyres were running within normal operating ranges compared to other cars.

It is not thought that the curbs caused the problem. Additionally, Williams have set up tyre deflection tests in Grove to verify what parts of the bodywork the tyre could have contacted during the high speed left hander at Istanbul. A number of changes will be made during the test this week to avoid the problem occurring again."
