Background
Livery
The 2025 livery was unveiled on 18 February 2025 at the F1 75 Live event at The O2 Arena with the other teams.
Competition and development history
During pre-season testing at Bahrain International Circuit, new signee Sainz set the fastest time.
The Australian Grand Prix saw both Williams cars enter Q3, with Albon qualifying sixth and Sainz tenth. However, Sainz experienced a torque issue with his car that sent him into the wall and into retirement. The lone Williams of Albon finished in fifth, the team’s highest finishing result since the rain-affected 2021 Belgian Grand Prix.
