Felipe Massa: "... We now need to look to prepare for Bahrain and then towards the first race, which is the most important thing."
Rod Nelson, Chief Test & Support Engineer: "It was a good day for us. It was what we were hoping for earlier in the week but it was good to start getting more mileage in the end.
We are very happy with the performance and reliability of the car up to now.
We still have a lot of work to do when we get to Bahrain and in the time leading up to then but overall, we are pleased with how we have ended the week here."
Felipe Massa: "It wasn't a great day because it was raining, but we completed some laps in the wet conditions which was interesting to understand how the car behaves in wet, with the tyres and new power unit. We managed to do many more laps today than we have in the last three days which is important.
Today we didn't have any issues with the car which I think is also another step forward. We now need to concentrate and prepare with an aim to do more laps per day in Bahrain. Overall, I'm happy with my first days with Williams and I'm pleased with what I have seen in the team this week.
For sure it is important to be competitive, but testing is testing, and we now need to look to prepare for Bahrain and then towards the first race, which is the most important thing."
