The Haas Formula 1 team replaced driver Esteban Ocon with reserve driver Ryo Hirakawa for the remainder of the Mexico City Grand Prix weekend. Hirakawa, a two-time WEC champion, took over starting from FP3 to partner Oliver Bearman for the final practice, qualifying, and the race.
The decision followed a disagreement between Ocon and his race engineer, Laura Mueller, during second practice regarding tire choice and the runplan. While Haas confirmed the replacement was not due to illness, Ocon later issued a statement denying rumors of a physical altercation with team boss Ayao Komatsu.
