Six engine manufacturers are signed up for the next F1 rules era that begins in 2026, with the potential for a seventh to join the ranks later on too. Here’s a look at which power unit suppliers the 10 existing teams will be partnered with when that cycle begins
In the next Formula 1 rules cycle starting in 2026, there will be five engine manufacturers providing power units, including Audi and Ford-supported Red Bull Powertrains joining Ferrari, Mercedes, and Honda. Red Bull created its in-house engine division, Red Bull Powertrains, partnering with Ford for the project set to debut in 2026. Mercedes operates its works team with a split chassis facility in Brackley and engine production by Mercedes-AMG High Performance Powertrains at Brixworth. Ferrari remains the only true works team in F1, housing every operation at its Maranello base while McLaren has extended its engine deal with Mercedes until at least the end of 2030. Despite initial withdrawal plans after 2021, Honda continued supplying engines under Red Bull Powertrains and announced an exclusive engine deal with Aston Martin for 2026, as part of their long-term F1 plan. Renowned as ‘Team Enstone’, the squad has aligned with Renault’s power since the 1995 season and from 2026 onwards, they will no longer have an engine programme, making a significant and permanent change.
