FIA confirms no new engine upgrades after final ADUO review

The FIA has confirmed that no further special allowances will be granted to manufacturers for 2026 and 2027 following the third and final ADUO review. Red Bull-Ford remains the combustion engine benchmark, while Mercedes received one extra engine homologation for each of those two seasons and Ferrari, Audi and Honda received two each.

Nikolas Tombazis, the FIA's single-seater director, defended the findings but acknowledged that the system needs to keep evolving to remain efficient, relevant and fit for purpose. The FIA said the first year of implementation had reinforced its belief in the ADUO concept.

Ferrari boss Frederic Vasseur said the engine deficit had been particularly frustrating. The next ADUO assessment will begin with the opening six races of 2027.
