In a significant development for the Formula One landscape, Williams Racing has officially announced the signing of Carlos Sainz. The move follows the earlier announcement that Lewis Hamilton will replace Sainz at Ferrari in 2025, leaving the Spanish driver without a confirmed seat for next season until now.
However, Sainz’s future has just been confirmed as he will join Williams for the 2025 FIA Formula One World Championship season and beyond.

Sainz’s journey to Williams
The 29-year-old Spaniard, who has been linked with a number of teams since Ferrari’s announcement, has finally committed his future to Williams. Sainz, a three-time F1 race winner, joins the Grove-based team on a two-year deal with options for further extensions. His career achievements include three race wins, 23 podiums and over 1,100 career points, which currently puts him fifth in this year’s Drivers’ Championship.
This season, Sainz has shown his talent with remarkable performances, including a victory in the Australian Grand Prix shortly after undergoing surgery for appendicitis.
He is also the only non-Red Bull Racing driver to have won a race in 2023. His consistent presence at the front of the grid underlines his skill and determination, making him a valuable asset to any team.
A new era with Williams Racing: Logan Sargeant ditched
Sainz will team up with Alex Albon to form a dynamic duo that will return Williams to the forefront of Formula One. With new regulations on the horizon, this pairing promises to bring new opportunities for the team. Sainz will continue to race under his distinctive number 55, a number that has become synonymous with his racing identity.
The move also signals the end of Logan Sargeant’s tenure with Williams. The Miami-born driver, who will join the team in 2023, made history by becoming the first US driver in 30 years to score a point when he finished 10th in Austin last year.
Despite his efforts, Sargeant struggled to deliver consistent performances, prompting Williams to seek a more experienced and proven driver in Sainz. Williams have expressed their commitment to supporting Sargeant as he continues his racing career beyond 2025.

Strategic driver market moves
While Williams were keen to secure Sainz, the Spaniard also considered offers from Sauber/Audi and Alpine. Despite the competition, Williams team principal James Vowles was confident of their chances. “Out of 100, more than 50 per cent. What do you think?” he told Autosport, highlighting the competitive nature of F1 driver negotiations. This confidence underlines Williams’ belief in their project and the attractive prospects they offer a driver of Sainz’s calibre.
Vowles stressed the importance of finalising the team’s line-up before the summer break following the Belgian Grand Prix. “I said that before we went into the summer break, yes. And I think there is a line that I have drawn. I hope we stick to it,” he said, indicating that negotiations are progressing as planned. Finalising the rider line-up early will allow the team to concentrate on preparing for next season without the distraction of unresolved contract negotiations.

The impact of Sainz’s decision
Sainz’s decision to join Williams marks a significant moment for both the team and the driver. For Williams, securing a driver of Sainz’s calibre is a major coup that will bolster their ambitions to climb back up the Formula One hierarchy. Sainz’s experience, skill and strategic acumen make him the ideal candidate to lead Williams into a new era of competitiveness.
For Sainz, joining Williams offers a fresh start and the chance to lead a team with a rich history in the sport. Williams, once a dominant force in Formula One, has struggled in recent years. However, with new management and strategic investment, the team is poised for a resurgence. Sainz’s arrival is expected to accelerate this process, bringing valuable insights from his time at top teams such as McLaren and Ferrari.

Carlos Sainz’s enthusiasm for the future
Commenting on his new contract, Sainz expressed his excitement and pride at joining a team with such a storied heritage. “I am delighted to announce that I will be joining Williams Racing from 2025,” said Sainz. “It is no secret that this year’s driver market has been exceptionally complex for a number of reasons and that it has taken me some time to announce my decision.”
“However, I am fully confident that Williams is the right place for me to continue my F1 journey and I am extremely proud to be joining such a historic and successful team where many of my childhood heroes have driven in the past and left their mark on our sport.”
“The ultimate goal of getting Williams back to where it belongs, at the front of the grid, is a challenge that I embrace with excitement and positivity. I am convinced that this team has all the right ingredients to make history again and from 1 January I will do my very best to drive Williams forward together with each and every member of the team.”
Sainz also acknowledged the crucial role of Williams’ leadership in his decision.
“I would like to thank James Vowles and the entire Williams Board of Directors for their confidence and determination. Their solid leadership and conviction played an important role in my decision. I truly believe that the core of any successful team is its people and culture.”
“Williams is synonymous with heritage and pure racing, the foundations of the project ahead of us are very strong and I am really looking forward to being part of it from next year.”
Williams’ vision and confidence
Williams Team Principal James Vowles was enthusiastic about the new signing. “Carlos joining Williams is a strong statement of intent from both parties. Carlos has shown time and again that he is one of the most talented drivers on the grid, with a race-winning pedigree, and this underlines the upward trajectory we are on. Carlos brings not only experience and performance, but also a fierce drive to squeeze every millisecond out of the team and the car; the fit is perfect.
Vowles highlighted the strength of the new driver line-up.
“In Alex and Carlos, we will have one of the most impressive driver line-ups on the grid, with tremendous experience to guide us into the new regulations in 2026. Their belief in the mission of this organisation shows the amount of work that goes on behind the scenes.”
“People should be in no doubt about our ambition and momentum as we continue our journey back to competitiveness – we are here, we are serious and with Dorilton’s backing we are investing in what it takes to get back to the front of the grid.”

Evaluating options and alternatives
While Carlos Sainz was the preferred candidate for Williams, Vowles had also considered other options, including Valtteri Bottas. The Finnish driver, currently with Alfa Romeo, is another experienced candidate who could bring valuable experience to Williams. Known for his consistent performances and experience with top teams, Bottas was a viable alternative should negotiations with Sainz fail. However, Vowles’ comments made it clear that Sainz was their first choice.
Bottas, with his vast experience and proven track record, could have provided Williams with a steady hand and valuable insight. His ability to perform consistently and bring home points would have been an asset. However, the dynamic potential that Sainz brings, combined with his recent form and younger age, ultimately tipped the scales in his favour.
