Formula 1’s 2026 season is still two-and-a-half-years away but already attention is turning to the new power unit regulations and partnership changes.
Six power unit manufacturers have signed up for the campaign, when new engine regulations will be introduced, which include greater electrical energy, the removal of the MGU-H, fully sustainable fuels, along with an engine cost cap.
Audi will make its much-anticipated entry into Formula 1 after forming a strategic allianece with Sauber Motorsport, which currently competes as Alfa Romeo.
Audi will eventually acquire a majority stake in Sauber, in time for its 2026 entry, and hopes to run its power unit in a mule car in 2025.
Ford will return after an absence of over two decades after forming a partnership with Red Bull Powertrains, while the latter’s current ally Honda will link up with Aston Martin.
Mercedes, Ferrari and Alpine (Renault) will partner their respective eponymous teams.
There will consequently be six works teams and four customer outfits from 2026.
McLaren and Williams are currently supplied by Mercedes but both British-based squads have the option to look elsewhere for the 2026 campaign.
Haas has been supplied engines by Ferrari since it joined the grid in 2016 and is expected to continue that partnership.
Below, see the full list of teams for the 2026 F1 season and the engine deals in place.
