Answer
Sebastian Vettel retired from Formula 1 at the end of the 2022 season, leaving a vacancy at Aston Martin. Nico Hülkenberg, who had previously raced for the team in 2020, was brought back to fill Vettel's seat. Hülkenberg had been serving as a reserve driver for Aston Martin and had made several appearances for the team in 2022, including the Canadian Grand Prix where he finished 17th.
