F1 2026: Who’s supplying who in new engine era
The 2026 F1 season is bringing significant changes to the sport, with new power unit regulations and aerodynamic design tweaks being the most substantial since 2014.
Power units now emphasize tripled electrical energy, with smaller, narrower, and lighter cars aimed at improving racing and moving towards carbon neutrality by 2030.
Cadillac and Audi are new entrants in 2026, with Audi also joining as a power unit manufacturer and taking over the Sauber team.
Honda now supplies Aston Martin, while Red Bull and Ford partner for power units, and Ferrari supplies Haas, Cadillac, and their works team. Mercedes remains a key supplier to McLaren, Williams, Alpine, and their works team.
The new power units feature increased electrical energy emphasis, with sustainable fuels for the internal combustion engine and enhanced energy recovery systems for better overtaking opportunities. Drivers can activate an ‘overtake mode’ for additional electrical energy during battles for position.
Managing the battery and ERS will be crucial in 2026, as drivers can now use a ‘Boost’ button to access additional energy for overtaking or defense.
