SILVERSTONE — The FIA announced the outcomes of investigations involving Isack Hadjar and Esteban Ocon following British Grand Prix qualifying on July 4, 2026. The motorsport federation also stated it would clarify the assessment of the Additional Development Opportunity (ADUO) engine for Red Bull Racing.

Stewards cleared Haas driver Esteban Ocon of an alleged yellow flag infringement at Turn 13. Stewards concluded no further action was warranted against Ocon after examining telemetry, which showed his speed was sufficiently reduced compared to a representative lap. Ocon stated he spotted white smoke further up the road before reaching the incident. Ocon added that he lifted off the throttle earlier than usual and remained off the throttle for a longer duration through that sector of the track.

Isack Hadjar was investigated for exceeding the maximum delta time between the Safety Car lines during qualifying. Stewards chose not to impose a penalty on Hadjar. They accepted that Hadjar exceeded the limit because he was making room for other cars. Stewards determined Hadjar maintained an appropriate pace for most of the lap and slowed only when necessary to allow faster drivers to pass safely.

Investigations involving Pierre Gasly and Lance Stroll remain ongoing. Gasly and Stroll were summoned over an alleged impeding incident at Turn 15 during Q1. The case involving Oscar Piastri and Arvid Lindblad is also pending. Arvid Lindblad was called to the stewards regarding an alleged unsafe release in the pit lane that forced Oscar Piastri to brake to avoid a collision.

The FIA will provide Red Bull Racing with clarification regarding the outcome of the ADUO assessment at Silverstone. A review by the motorsport federation did not prompt changes to earlier conclusions regarding the ADUO assessment. Red Bull had requested a reassessment of the ADUO measurements. The ADUO system determines which engine manufacturers receive additional development opportunities in 2026, focusing exclusively on the performance of the internal combustion engine. The FIA concluded that Red Bull possesses the strongest combustion engine after the first round of measurements, meaning Red Bull is not allowed to implement extra engine upgrades. Speaking on the matter, Red Bull team boss Laurent Mekies stated, “Red Bull’s own data shows no indication that the combustion engine outperforms Mercedes’.”

FIA single-seater director Nikolas Tombazis invited Red Bull to review the data at Silverstone. Oliver Mintzlaff and Mark Mateschitz are expected to attend this meeting representing Red Bull. A meeting with FIA president Mohammed Ben Sulayem is also scheduled to discuss Red Bull’s involvement in motorsport. The new review of the Red Bull ADUO case took eight days, with the FIA assigning ten staff members to the case.
