Rob Smedley, Head of Vehicle Performance: We had good mix of tests today with aero, mechanical, car set-up, electronics and power unit, and we managed to get through everything which is hugely encouraging. The results were very positive and we collected a lot of good data, which is good news. Valtteri also did a good job for us today. We are pleased to be running here as it has given us that chance to build on the data from the weekend and means we have continued development from the start of the race weekend. Felipe Nasr will be in the car for us tomorrow as we complete a 2015 tyre test programme for Pirelli.

Valtteri Bottas: Overall it was a good day as we managed to complete the programme as planned. We then worked on set-up and we were quite experimental, so hopefully that will help in the next few races. Next it was time to test some new aero components with some positive results. The track conditions were different from the race, but actually better for testing as there was less wind.
