Sauber's signing of Brazilian Gabriel Bortoleto means at least one-fifth of the 20-driver Formula One grid will be starting their first full season in 2025, with a new wave of young talent coming up fast.

"We are currently witnessing a generational shift in Formula One, with young drivers immediately making an impact," Sauber Motorsport Chairman and Audi Chief Executive Gernot Dollner said in a statement announcing Bortoleto's arrival.

Bortoleto, 20, will be lining up against fellow rookies Kimi Antonelli (18), Oliver Bearman (19) and Jack Doohan (21) who have secured seats at Mercedes, Haas and Renault-owned Alpine respectively.
