Williams Racing revealed via social media on Friday that they will unveil their 2021 car, the FW34B, on March 5.
With pre-season testing scheduled to take place a week later and the first race set for March 28, the Grove outfit will be hoping to see progress under new owners Dorilton Capital this season.
Williams have finished last in the constructors’ championship during each of the last three seasons and failed to score a point in 2020.
With George Russell and Nicholas Latifi confirmed to drive the car for a second consecutive season, they will run a Mercedes power-unit once again, having signed a new deal with the German manufacturer until 2025.
The two teams also agreed for Mercedes to provide Williams with gearboxes and hydraulic components from next season.
Williams are the fifth team to declare a launch date for their 2021 car, with McLaren (15 February), AlphaTauri (February 19), Alfa Romeo (February 22) and Mercedes (March 2) the others to do so.
