Haas replaces Esteban Ocon with Ryo Hirakawa for Mexico City Grand Prix

Haas abruptly announced on Saturday, October 31, that Ryo Hirakawa would replace Esteban Ocon at the Mexico City Grand Prix. The reserve driver is set to make his Formula 1 race debut on Sunday, according to Associated Press.

The timing is important. This was not a switch announced before the weekend began: Associated Press described it as a rare change part-way through an F1 weekend.

The October 31 announcement put Hirakawa into Ocon's seat for the remainder of the event, Sky Sports reported. Its coverage described the replacement as unexplained.

The change covers both remaining competitive stages. Ocon will take part in neither qualifying nor the Grand Prix, according to L'Équipe.

Hirakawa will join Ollie Bearman in the Haas lineup for what is the nineteenth round of the 2026 season, Infobae reported. That makes the late substitution a race debut rather than simply a practice appearance.

Hirakawa is now the Haas driver scheduled to race in Ocon's place in Mexico City, as BBC Sport reported. The reported scope of the change is the remainder of this Grand Prix weekend.

The central uncertainty is why Haas made the switch. Associated Press and Sky Sports both described the decision as unexplained; the supplied coverage establishes no reason for Ocon's absence.

Qualifying is the next competitive step for Hirakawa before Sunday's planned race debut. L'Équipe reported that he would replace Ocon for both sessions.

Any explanation from Haas would clarify the biggest unanswered part of the announcement. The coverage does not establish whether the substitution has implications beyond Mexico City.
