Formula 1 has confirmed a broad set of regulatory changes for the 2026 season. New technical and sporting rules cover car dimensions, aerodynamics, power unit structure, active aerodynamic systems, terminology updates replacing the drag reduction system, and updated livery and driver number rules.
With Audi and Honda joining the grid and Renault stepping out, F1 enters its most diverse power unit era yet in 2026. The FIA’s new “ADUO” system promises to prevent major performance gaps by giving underperforming manufacturers extra development opportunities.
