Speaking after recent meetings, Carlos Sainz, Williams driver and GPDA director, says Formula 1’s engine update process stalls because manufacturers wield outsized influence, slowing consensus on post‑2026 rules.

During April’s break, the FIA, F1, teams, and manufacturers meet to agree interim steps for Miami. The super‑clipping ceiling rises to 350 kW, while total deployable energy drops to 7 MJ.

Work continues on the 2027 package, targeting a 50‑50 split between combustion and electrical output. That direction follows debate over engine rule delays and drivability under the 2026 framework.

Governance sits with the Power Unit Advisory Committee. Proposals need at least four of five manufacturers, plus FIA and F1, to pass. Mercedes HPP, Ferrari, Honda, Audi, and Red Bull Powertrains vote.

Sainz says several manufacturers resist changes that might compromise current advantages. He frames the impasse as political alignment rather than engineering impossibility, describing agreement as the main blocker.

He argues the grid would adapt if the FIA imposes firmer decisions. For now, he describes ‘strings attached’ and some parties pulling strings across negotiations to defend competitive positions.

In his GPDA role, Sainz says he supports substantial 2027 changes even as Williams runs Mercedes power. He stresses sporting benefit over manufacturer advantage, accepting potential impacts on that customer engine.

McLaren team principal Andrea Stella advocates deferring the bigger reset to 2028. More time, he argues, allows issues to be solved methodically before introducing drastic steps alongside the 2027 chassis.

Timing matters for development cycles and competitive balance. Any delay reshapes investment priorities and test programmes, feeding into a wider FIA rule change debate as the 2026 season approaches.
