Massa quickest for Williams in Silverstone Test Day One

Driver: Felipe MassaChassis/Engine: FW36-03 / PU106 HybridLocations: Silverstone, Great BritainObjectives: Aero and Systems workWeather: Mild and DryMaximum air & track temps: 23°C / 28°C

Rod Nelson, Chief Test and Support Engineer: At one point today we had rain surrounding the whole track so for it to not affect running today was very lucky. It was a successful day, the main plan was for aerodynamic and systems tests for this year and also moving forward for next year's car, and we are very pleased with the progress.

Felipe Massa: The car was very competitive during the race so today we have built on a very good platform. The test today was experimenting with some parts for future races as well as a little bit for next year. The car felt really good, so we know we will go to Hockenheim with a good car. The programme went to plan today and we didn't have any rain so it was a very productive day
