Background
Development context
Sauber unveiled the car's livery at the F1 75 Live event on 18 February 2025.[2] The C45 chassis was later revealed in digital renderings immediately following the event.[3] The car has been designed to build on a late-season aerodynamic and cooling package brought to the Kick Sauber C44.[3] After experiencing significant stiffness and handling issues during pre-season testing, technical director James Key brought forward an upgrade package that was due during the early rounds of the season.[4] As a result, the cars that appeared at Albert Park for the first round bore many aerodynamic and internal differences to the pre-season version of the car.
Competition and development history
The C45 made its public debut at Bahrain International Circuit during official preseason testing. Prior to the car's debut, both drivers completed testing programmes in the C44 at Yas Marina and in the C42 at Circuit de Barcelona-Catalunya under the Testing Previous Cars (TPC) programme.[5] On its competitive debut at the 2025 Australian Grand Prix, Bortoleto reached Q2 in qualifying, but retired from the race, and Hülkenberg finished in seventh position to score six points.[6] As a result, the C45 achieved more points in its first race than its predecessor scored throughout the entire 2024 season.
