Despite his impressive performances, the 2025 grid was already full by the time Colapinto arrived on the scene. Undeterred, he remained close to the action, joining Alpine F1 Team as a Reserve and Test Driver for the 2025 season. Over the past months, he completed extensive testing in previous-generation machinery, attended the opening rounds of the season in Melbourne and Shanghai as Alpine’s reserve driver, and played a key role in car development through simulator work across the remaining race weekends.
