Overview
- From 2026, drivers may change their career race numbers, ending the fixed-number system introduced in 2014, with implementation details yet to be set.
- Teams must cover at least 55% of each car’s side and top surfaces with paint or stickers to boost on‑track distinction and curb bare‑carbon designs ahead of lower 2026 weight targets.
- A compulsory two‑stop regulation was not approved after Pirelli and team analysis, and discussions on tyre‑use prescriptions will continue into 2026.
- The FIA is developing updates to Aerodynamic Testing Restrictions to reflect modern processing and simulation capabilities while considering costs.
- Decisions were taken at the final 2025 F1 Commission meeting in London chaired by Nikolas Tombazis and Stefano Domenicali, with topics like driver cooling and engine‑use within the cost cap still under review.
