FIA could not ‘twist Renault’s arm’ over 2026 F1 quit decision
FIA single-seater technical chief Nikolas Tombazis states that there will be no pressure to retain a manufacturer as an F1 power unit supplier following Renault’s withdrawal. Renault’s decision to end its works F1 power unit program and switch to customer Mercedes units for its Alpine team signals a major shift ahead of the 2026 regulation reset. Despite Renault’s exit, Honda has returned to the F1 power unit scene with Red Bull and will collaborate with Aston Martin from 2026. The FIA aims to have Honda, Ferrari, Mercedes, Red Bull Powertrains, and Audi as the remaining PU suppliers after Renault’s departure. Tombazis emphasizes that while Renault contributed to shaping the 2026 rules, the FIA cannot mandate their continued presence in F1 if they choose to leave.
