Williams: We know there is still more to come

Williams report on day two of the final Formula 1 preseason test at Circuit de Catalunya in Barcelona.

Rod Nelson, Chief Test & Support Engineer: "We started the day doing some aero work comparing data and driver feel. We then moved onto a few performance based runs. Later in the day we worked on race procedure including some longer runs and grid simulations. We have had some new components that have performed as expected which has been productive. We have a busy final two days of the test as we optimise the time left until the first race."

Valtteri Bottas: "It was nice to focus on performance and work to get the lap times lower. We are working hard and still have two days left of the test so there is more still to do. The day was busy and we know there is still more to come, I feel positive and the balance was good. We still need to make sure we look at the longer runs and not just the one lap qualifying pace."
