Gabriel Bortoleto has been confirmed as the second half of Sauber's 2025 line-up, partnering Haas' Nico Hulkenberg in an all-new driver pairing for the Hinwil-based team.

The 20-year-old Brazilian is the reigning Formula Three champion and is well on his way to adding a Formula Two title in consecutive seasons. He leads Isack Hadjar by 4.5 points heading into the final two rounds.

Despite being a McLaren junior prospect, Sauber's interest in Bortoleto has been long-standing and with their line-up secured for the long term, Andrea Stella has been very cooperative.

Speaking in the aftermath of the announcement, Bortoleto said: "This is one of the most exciting projects in motorsport, if not in all of sports. Joining a team that combines the rich motorsport history of Sauber and Audi is a true honour.

"Beyond simply being a member, I aim to grow with this ambitious project and reach the pinnacle of motorsport. I’m incredibly grateful for the opportunity given to me by the team and for the chance to work alongside an experienced driver like Nico."

"Both programs have a proven track record of nurturing young talent, and I am confident that together, we will write our own success story.”

While Bortoleto's arrival on the grid is an exciting development, fans will now have to say goodbye to Valtteri Bottas as the Finn is left without a full-time drive for the 2025 campaign. A return to Mercedes in a reserve role is reportedly looming, but his future looks to lie in IndyCar, rather than in F1.

"A situation like this is never easy for anyone," Bottas said after the announcement. "But after all the good and in-depth discussions we had in the past weeks, we realised that the conditions to grow this project together were not met. These past years with the team have been an incredible journey, full of growth, challenges, and unforgettable moments.

"I’m grateful for the joint experiences as well as the trust and support I’ve felt every step of the way. Though it’s time to move on, I’ll always carry a piece of this team with me, and I look forward to seeing what the future holds for us both.”
