- Michael completed 51 laps today, taking the F1 W03's total mileage to782 km to date

Nico will take over the programme tomorrow, with Michael back in the car on Thursday, and Nico concluding the test on Friday.

Michael Schumacher"My initial feelings with our new car are certainly good. I'm happy with the different evaluations that we have done over the last week, but obviously with the rule changes, we won't know more until later. It's certainly an improvement and we have worked hard on the areas we had defined last year. The aerodynamics figures look good so I'm not worried about the shape of the nose! Even though we had the hydraulic problem today, I'm pleased with all the mileage we have achieved so far with the new car."
