F1’s 2026 season begins a new era: Which engine will each team use this year?

The 2026 Formula 1 season kicks off this weekend in Australia, ushering in a brand‑new era defined by a radically updated technical rulebook. The biggest change comes under the engine cover: teams will continue using 1.6‑liter turbo‑hybrid V6s, but with a massive increase in electric power—nearly a 50‑50 split between combustion and battery output. All cars will also run on 100% sustainable fuel, making energy management and battery regeneration one of the defining challenges of the new regulations.

This year’s grid expands to 11 teams, thanks to the arrival of Cadillac and Audi. Audi has taken over the Sauber operation and will build its own power units, joining a roster of engine manufacturers that includes Mercedes, Ferrari, Honda, and Ford. Here’s how the 2026 power‑unit landscape breaks down.

Mercedes

Mercedes will supply engines to four teams:

McLaren has a long history of engine partnerships—11 in total—including Mercedes (99 wins), Honda (44), Ford Cosworth (35), Porsche (68), Renault, Peugeot, BRM, Alfa Romeo, Serenissima, and Climac.

Williams has also worked with a wide range of manufacturers: Mercedes, Renault (64 wins), Ford Cosworth (17), BMW (10), Honda (23), Toyota, Judd, Supertec, and Mecachrome.

Alpine is the newest Mercedes customer after years running Renault engines, with one win under that partnership.

Ferrari

Ferrari will power three teams:

Haas has used Ferrari engines since joining F1 in 2016. Cadillac enters the sport as a Ferrari customer while it develops its own power unit for future seasons.

Ford–Red Bull

Red Bull ended its partnership with Honda‑Red Bull Powertrains at the end of last season—an engine program that delivered 38 wins—and has now teamed up with Ford. Ford will supply engines to both Red Bull Racing and Racing Bulls.

Before this new alliance, Red Bull teams had run engines from Renault (50 wins), TAG Heuer (10), Honda, RBPT (17), Ferrari, and Cosworth.

Honda

Honda Racing Corporation (HRC) will supply engines exclusively to Aston Martin, which ended its long‑running relationship with Mercedes after the 2025 season. Aston Martin previously built its own engines in the late 1950s, competing in five races in 1959 and 1960.

Audi

Audi officially joins Formula 1 as a manufacturer after acquiring Sauber and will debut its own power unit in 2026. While new to F1, Audi brings a heavyweight motorsport résumé:
