The FIA has announced the introduction of a mechanism to ensure a level playing field across F1's power unit manufacturers ahead of the 2026 rules revolution.
For next season, the power units are to undergo their biggest change since the turbo hybrids were introduced in 2014, with the electrical systems to be beefed-up to 350kw from the current 120kw, with the MGU-H set to be removed with sustainable fuels also set to be introduced.
Audi is entering a works project for the first time in F1, with Red Bull Powertrains also debuting as Honda rejoins as a full works operation, joining Mercedes and Ferrari as suppliers, with Renault set to withdraw at the end of the current season.
Given the complexity of the new regulations, a wide spread of performance is expected from the power units, with the FIA announcing the introduction of the Additional Development and Upgrade Opportunities (ADUO) concept at a meeting of the World Motor Sport Council.
The ADUO is intended to "provide greater development opportunities for PU manufacturers who find themselves significantly behind their competition in terms of performance," read a statement.
With 24 races planned in 2026, after each quarter of the season - after races six, 12, and 18, ADUO development could be allocated to address poor performance, including additional cost cap relief or development hours on power unit test benches.
Moreover, measures to provide cost cap relief to those manufacturers facing "serious reliability issues that could otherwise be very damaging under the cost cap" has been agreed.
Elsewhere, minor changes to the 2026 technical regulations relating to the survival cell, suspension, aerodynamic components and power units have been made, as well as to the power unit-only financial and operational regulations.
