Audi and Ford/Red Bull Powertrains are both currently developing new power units for the first year of the new rules in 2026, while Cadillac intends to enter as a manufacturer in the third season in 2028 with the mooted Andretti team.
The change to the new rules is a tricky one, even for the established manufacturers who already have a decade of experience with F1 hybrids, but Gualtieri says it will be harder for those coming in with no knowledge of the previous generation: as well as creating power units for 2026, they also have to develop new infrastructure.
