Carlos Sainz will join Williams for the 2025 Formula 1 season.
The Spanish driver has agreed to a multi-year contract with the team, leaving Ferrari to make the switch. This decision comes after Sainz’s opportunities with top teams like Mercedes and Red Bull diminished, making Williams and Audi his primary options for the future.

Williams offered Sainz a four-year contract, with a crucial break clause allowing him to leave after two years if the team’s performance doesn’t meet expectations. This flexibility played a significant role in his decision, giving him the option to reassess his career trajectory once the new F1 regulations take effect in 2026.

Williams has been making substantial changes to improve its competitiveness, including strategic hirings and securing a strong power unit deal for 2026. The team’s principal, James Vowles, has expressed confidence that these developments will attract top talent like Sainz and help Williams return to the forefront of F1.
