Alpine's 2025 signing Jack Doohan will replace Esteban Ocon at the season-ending Abu Dhabi Grand Prix, the team confirmed Monday.
Doohan, son of motorbike racing legend Mick, will make his debut at the Yas Marina circuit on Dec. 8.
Speaking to reporters after Sunday's Qatar Grand Prix, Alpine boss Ollie Oakes said the move would enable the 21-year-old to "get those butterflies gone now rather than next year in Australia."
Ocon, who won for Alpine at the 2021 Hungarian Grand Prix, has already confirmed a deal to race for Haas for next season.
Leaving early will allow Ocon to test for Haas in the test at the Yas Marina circuit the week after the race, with Doohan set to take part for Alpine.
The team's statement said: "The team would like to thank Esteban for his time at the team and he will remain part of the team's history achieving the first win for Alpine in Formula 1. We wish Esteban the best for the future."
The announcement had no quotes from either driver, but Ocon's comments to the media after the Qatar Grand Prix had sounded like he was saying farewell to the team.
Doohan was part of the Red Bull driver academy between 2018 and 2021, but switched to the Alpine academy in 2022.
The Australian, 21, finished second in the 2021 Formula 3 championship and third in the 2023 Formula 3 championship.
