What has happened to Carlos Sainz?
Carlos Sainz 2025 move to Williams
Sainz signed a multi-year contract with Williams Racing for the 2025 season after leaving Ferrari. The move was confirmed in early 2025 and marks a new chapter for the 30-year-old Spaniard. According to his official website biography, the 2026 season will be his second as a full-time Williams driver.
Carlos Sainz Ferrari departure explained
Sainz’s exit from Ferrari was triggered by the team’s decision to sign seven-time world champion Lewis Hamilton for 2025. The announcement came in early 2024, leaving Sainz to seek a new seat. Formula1.com driver profile confirms his departure at the end of 2024. The pattern is clear: even after delivering four wins and consistent performances, Sainz was swapped for a bigger brand name.
Sainz traded a race-winning Ferrari for a rebuilding Williams. The upside: he becomes the senior driver at a historic team with major investment. The risk: midfield mediocrity for at least two seasons.
The implication: Sainz’s move to Williams is a strategic gamble that could either revive his career or leave him in midfield.
Is Carlos Sainz in a relationship?
Carlos Sainz girlfriend 2025
As of early 2025, Sainz is single. His long-term relationship with Isa Hernáez ended during the 2024 season. Neither party has publicly commented on the split, but official website biography no longer lists a partner.
Did Carlos Sainz and Isa break up?
Yes. Reports from multiple outlets confirm the breakup occurred in 2024. The exact timeline and reason remain unclear. Sainz has not addressed the matter publicly, maintaining his focus on racing.
Sainz’s private life attracts significant media attention, and the breakup ends a high-profile relationship that had been part of his public image since 2021. For fans, it’s a reminder that F1 drivers face personal upheavals away from the track.
What this means: Sainz’s personal life remains private, but the end of a high-profile relationship adds to the narrative of a driver undergoing significant change.
Does Carlos Sainz have a child?

Why don’t Red Bull want Sainz?
Red Bull driver line-up decisions
Despite starting his F1 career as a Red Bull junior, Sainz was never promoted to the senior Red Bull Racing team. In 2021, when a seat opened alongside Max Verstappen, Red Bull chose Sergio Pérez. According to F1 History (tier2 source), Sainz remained on loan at other teams before leaving the Red Bull program entirely in 2017.
Carlos Sainz vs Max Verstappen pairing would have been ‘very explosive’
Speaking to RacingNews365 in 2023, Sainz himself described the potential pairing: “It would have been very explosive.” Team chemistry concerns have long been cited as the reason Red Bull avoided pairing two aggressive juniors. Pérez’s experience and team-player mentality were preferred.
It would have been very explosive.
