Rod Nelson, Chief Test & Support Engineer: It was another productive day to end the test. We spent most of the time with Felipe looking at the aero performance of the current car and looking into development work for next year as well. It was a fairly positive day with a clear direction, and we’ll be using that data to feed back into the development work we are doing at the moment for this year’s and next year’s car.Felipe Massa: It was an interesting test. We worked on so many things for developing and improving the car on the aero side, which was our biggest aim for these two days. We tried a lot of different things for the future so it has been an important two days and key to get a lot of mileage. Williams Martini Racing will be back on track next week for the Monaco Grand Prix.
