Sauber is the very first team to unveil the car at the F1 75 event. Like last year, the car is green and black because of title sponsor Stake.
For the first time, all cars will be revealed at a major joint event prior to a Formula 1 season, the F1 75 Live, at the O2 Arena in London. Some teams had already revealed their cars before the event in London, but Sauber chose to wait until F1 75, with Nico Hulkenberg and Formula 2 champion Gabriel Bortoleto doing the honors for the Swiss-based team, which said goodbye to Valtteri Bottas and Guanyu Zhou, ahead of their transition to Audi in 2026.
