Dickie Stanford, Test Team Manager, Williams F1:
"Kazuki was on duty today and took over from where Nico Hulkenberg left off yesterday, continuing with tyre testing and general set-up work. We lost a small amount of track time this morning due to the icy weather, but the car has been running well and we've had no other problems. Kazuki will continue in the car tomorrow for our last day of testing this year."
