The 2026 FIA Formula One World Championship is a planned motor racing championship for Formula One cars which will be the 77th running of the Formula One World Championship. It is recognised by the Fédération Internationale de l'Automobile (FIA), the governing body of international motorsport, as the highest class of competition for open-wheel racing cars. The championship will be contested over several Grands Prix held around the world. Drivers and teams are scheduled to compete for the titles of World Drivers' Champion and World Constructors' Champion respectively.
The 2026 season will feature a major set of regulation changes with a revised power unit configuration and new active aerodynamics. Two new power unit manufacturers will enter the sport and one will leave: Ford will return to the sport for the first time since 2004, supporting Red Bull Powertrains in supplying Red Bull Racing and Racing Bulls, while Audi, who acquired Sauber in 2024, will enter as a works team. Renault will leave the sport, making it the first time that the manufacturer will not compete with any sort of Renault-licensed engine since the 1988 season. Cadillac will become the eleventh team to join the series.
