Williams say it was “embarrassing” to miss two days of pre-season testing because their car was not ready.
Claire Williams: “It’s embarrassing not bringing a race car to a circuit when everyone else has managed to do that, particularly a team like ours that has managed to bring a race car to testing for the past 40-odd years.”
Kubica is due to drive the car on Friday morning, before Russell runs again in the afternoon, and Williams is hopeful the team will be able to make up for lost time.
