The Kick Sauber C45 is a Formula One car designed and constructed by Stake F1 Team Kick Sauber to compete in the 2025 Formula One World Championship. It was driven by Gabriel Bortoleto and Nico Hülkenberg in the team's final year before becoming the Audi factory team in 2026. Designed as an evolution of the Kick Sauber C44, a series of successive upgrades starting at the Spanish Grand Prix significantly increased the team's competitiveness. After scoring three consecutive points finishes, Hülkenberg achieved the team's first podium since 2012 at the 2025 British Grand Prix.
