Isack Hadjar has been disqualified from qualifying for the Miami Grand Prix after his Red Bull Racing RB22 failed post-session scrutineering checks, the FIA confirmed on 3 May.
The French driver had qualified ninth but was excluded after technical inspectors found his car’s left and right-hand side floor boards protruding 2mm outside the permitted boundaries defined in the technical regulations.
Technical Breach Confirmed
The infringement represents a violation of Article C3.5.5 of the FIA Formula 1 Regulations, which governs the dimensional limits of floor components. Red Bull representatives did not dispute the technical delegate’s findings during the stewards’ hearing.
“The Stewards heard from the team representatives of Car 6 (Isack Hadjar). They did not dispute the findings of the Technical Delegate that portions of the LHS and RHS floor boards were protruding 2mm out of the reference volume RV-FLOOR BOARD. This is a breach of Article C3.5.5 of the FIA F1 Regulations and the usual consequences follow an admitted breach of the technical regulations.”
The 2mm protrusion, whilst small in absolute terms, places the floor outside the tightly controlled reference volume that defines legal bodywork dimensions under the 2026 technical regulations. Floor design remains one of the most aerodynamically sensitive areas of the current generation of cars, with teams pushing boundaries to extract performance within the regulatory box.
Grid Reshuffle
Hadjar’s exclusion means the rest of the field shuffles forward one position on the starting grid. The Frenchman will start from the pit lane if Red Bull Racing opts to run him in Sunday’s race, though the team retains the option to withdraw the entry entirely.
The disqualification marks a setback for Hadjar and Red Bull ahead of a Miami Grand Prix already complicated by severe weather forecasts that have forced race officials to bring the start forward by three hours to 1pm local time.
The 2026 Miami Grand Prix takes place at the Miami International Autodrome on 3 May 2026, with the revised 1pm local start time designed to avoid forecast thunderstorms.
