Bahrain, maintaining his position to take his maiden victory in Formula 2 on his 96th race start. On Sunday, he once again finished on the podium, taking second after capitalising on a chaotic opening lap. Talking about his weekend, Boschung described his car as "incredible", saying that the team's baseline race pace was better than it had been during the previous season. In
Jeddah, Boschung qualified in ninth, and took the standings lead after finishing in a strong fourth place during the sprint race. Since then, Boschung failed to score points for the next eight rounds. In
Spa-Francorchamps, Boschung returned to the top-ten in qualifying with seventh, having taken advantage of unpredictable rainy conditions. From there, it would yield a double points finish, ending the races in eighth and tenth place. His last points finish came in the
Monza feature race, coming home ninth in an incident-marred race. He finished 16th in the standings, with 37 points. Boschung was the only driver to have contested in every season of the modern era in the
