FIA considers F1 engine regulation reforms
The FIA is evaluating potential reforms to the ADUO system, which was introduced in 2026 to help struggling engine manufacturers close performance gaps. The review follows several unintended consequences and controversies regarding how the system is applied.
One major point of contention is that the current ADUO ranking is based exclusively on internal combustion engine power, failing to account for the total performance of the power unit. This has created a paradox where teams like Mercedes, which possess highly efficient thermal-electric units, can access development opportunities, while teams like Red Bull are restricted due to the high power of their combustion engines.
The proposed changes aim to improve the mechanism for all constructors and provide specific support to Honda. Discussions among engine manufacturers are expected to take place this week, with regulatory adjustments already planned for 2027.
