Valtteri Bottas will leave Sauber after the 2024 Formula 1 season but is understood to already be close to signing back with Mercedes as its reserve driver from next year.In what has been an awful year for Sauber – still 2024's only point-less team – Bottas's place beyond the deal he struck when leaving Mercedes at the end of the 2021 season,

Sauber moved quickly to tie Nico Hulkenberg down for 2025 earlier in the year, and with the German already 37 years of age, Mattia Binotto opted for youth over experience in his second seat, choosing Formula Two championship leader Gabriel Bortoleto over Bottas.

Formula 2 points leader Gabriel Bortoleto's hire as part of Sauber's overhauled 2025 Formula 1 driver lineup, effectively means the end of the road for current driver pairing Valtteri Bottas and Zhou Guanyu. Sauber will run with Bortoleto and current Haas driver Nico Hulkenberg next season.

Formula 1 team Kick Sauber has confirmed that long-time drivers Valtteri Bottas and Zhou Guanyu will depart after the season concludes.

Sauber also confirmed Zhou Guanyu’s departure, ensuring a fresh start for the team with two new drivers in 2025, including Nico Hulkenberg
