Williams have retained the dramatic-looking rear-wing endplates that they introduced last time out in Austria. They now feature a different vertical straked section at the bottom rear, designed to better manage the airflow vortices coming off the car.

Friday in Great Britain saw both Williams drivers test the new front wing that was debuted - but ultimately not raced - on Felipe Massa’s car in Austria. Here it has been integrated with the more squared vertical nose pillars (inset) used in Canada, but not seen since on the FW38. However, both Massa and Valtteri Bottas reverted to the previous wing (as raced in Spielberg) for Silverstone qualifying and race.
