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
For the 2026 Formula 1 season, there will be a total of six engine manufacturers, an increase of two compared to the current list. Audi and a Ford-supported Red Bull Powertrains program will join Ferrari, Mercedes, Honda, and Alpine (Renault), making it the first change in the roster since 2015. Additionally, there is the potential for a seventh manufacturer, the Andretti-Cadillac project, as it has been approved by the FIA and is in negotiations with F1 for commercial terms. Each of the 10 existing teams has partnered with a specific supplier for the 2026 season. Red Bull, after Honda’s departure, has set up its own in-house engine division, Red Bull Powertrains, with Ford as a partner. Mercedes continues to split its works team across two bases, one for the chassis in Brackley and another for engine production in Brixworth. Ferrari remains the only true works team in F1, having its operations centralized at its Maranello base. McLaren has reunited with Mercedes as an engine supplier until at least 2030. Honda, despite announcing its withdrawal, continues to supply Red Bull under the Red Bull Powertrains banner. Aston Martin, currently supplied by Mercedes, will have exclusive use of Honda’s 2026 engine, marking a significant step in their long-term F1 plan. Renault’s works team will also participate in the 2026 season.
