The Audi R26 is a Formula One car that was designed and constructed by Audi to compete in the 2026 Formula One World Championship. It is currently being driven by Nico Hülkenberg and Gabriel Bortoleto, both drivers continuing their contracts from when the team was named Sauber.
The R26 is the first Hinwil-based Formula One car to utilize non-Ferrari engines since the BMW-powered BMW Sauber F1.09 in the season, also the first Hinwil-based Formula One car to utilize Castrol-branded lubricant since the Ford Cosworth-powered Sauber C14 in the season and also the first Formula One car to carry the BP and Castrol logos brands since Renault-powered Alpine A524 in season.
Significant changes to the technical regulations were introduced for 2026, affecting both the chassis and engine.
On 19 December 2025, Audi completed its inaugural fire-up of the car at the team's Hinwil site in Switzerland. Their first shakedown of the R26 took place on 9 January 2026 at the Circuit de Barcelona-Catalunya and it was officially launched on 20 January 2026 at the Kraftwerk in Berlin.
