Defending Sixth Under Changing Skies

The Alfa Romeo C43 arrived in 2023 tasked with defending the competitive ground gained during the previous year's breakthrough campaign. The car retained the same driver pairing of Valtteri Bottas and Zhou Guanyu but faced a significantly evolved midfield where every team had learned from the 2022 reset. The C43 showed early season promise, Bottas' qualifying pace in Bahrain suggested the car was in good shape, but as the season progressed and rivals continued to develop aggressively, Alfa Romeo found it increasingly difficult to match the trajectory of teams with greater resources. The team finished a creditable seventh in the final standings with 16 points.

Transition Looms: Audi's Entry Announced

The most significant backdrop to the C43 season was not on-track performance but the structural transformation awaiting the team. The announcement of Audi's entry into Formula 1 as an engine supplier, eventually as a full works team taking over the Sauber infrastructure, changed the long-term vision entirely. The Hinwil operation began repositioning itself as the foundation for a future works effort, with Audi investment gradually flowing into personnel, facilities, and processes. For those paying close attention, the C43 season was as much about building the platform for 2026 as it was about competing in 2023.

Bottas and Zhou Maintain Professionalism

Both drivers maintained their composure and professionalism through a season of fluctuating expectations. Bottas' qualifying speed remained one of the C43's strongest attributes, and he extracted maximum value on the circuits that suited the car's characteristics. Zhou continued to develop as a Formula 1 driver and contributed meaningful data to the engineering team's development programme. As the Alfa Romeo branding began its final year, to be replaced by Kick Sauber for 2024, the C43 represented the closing chapter of a specific era for a team with roots stretching back to Peter Sauber's original outfit.
