The Cadillac F1 squad is continuing to take shape as it has signed an IndyCar race-winner to its driver line-up.
The Cadillac F1 team has signed IndyCar race winner Colton Herta as a test driver, preparing for its debut F1 season next year and expanding the grid to 22 cars.
The team’s full-time drivers are F1 veterans Valtteri Bottas and Sergio Perez, with Herta supporting them throughout the season.
Herta expressed great excitement about the opportunity, as he sees this as a significant step towards his dream of racing in Formula 1.
While his racing plans for 2026 will be announced later, Herta will participate in FP1 sessions next year to help build a competitive team.
His potential move to Formula 2 in 2023 could pave the way for a full-time F1 drive in the future, following Red Bull’s interest in him earlier.
