The 30-year-old made his official debut with the team during the 2024 Abu Dhabi tyre test, as he drove in the car for the first time and prepared to race alongside Alex Albon for the upcoming season.
Will Colapinto return to F1?
However, Sainz’s arrival at Williams left Franco Colapinto without a drive in F1 for 2025, as the Argentine was unable to acquire a seat elsewhere.
The youngster was initially tipped to join the Red Bull family, but a drive at neither Red Bull or Visa Cash App RB materialised after Liam Lawson and Isack Hadjar were promoted to the two teams respectively.
Colapinto has also been linked to Alpine, but Jack Doohan is expected to compete with the team all year unless his performances do not match the expectations of his bosses.
An opportunity on the F1 grid could open up for Colapinto in 2026, as Cadillac joins as the 11th team, but it seems the 21-year-old remains committed to Williams.
Colapinto has expressed his desire to remain at the team as their reserve driver in 2025 rather than chase a seat elsewhere, with Williams also providing an update on his contract for this year.
In a statement provided to GPFans, Williams said: “Franco is a Williams Racing driver and we will announce his 2025 programme in due course.”
