Ocon Disqualified From Azerbaijan GP Qualifying After Haas Rear Wing Rule Breach

Esteban Ocon was disqualified from the 2025 Azerbaijan Grand Prix qualifying session after his Haas VF-25 failed the FIA's rear wing deflection test, exceeding the allowed limit of 0.5mm with measurements of 0.6mm on the left and 0.825mm on the right side. This rule was tightened earlier in the season to prevent aero-elasticity exploits, reducing the allowed deflection from 2mm to 0.5mm. The Haas team acknowledged the issue stemmed from a production problem in assembling this specific rear wing part. Despite the disqualification from qualifying, Ocon is permitted to start the race but will be relegated to the back of the grid or could opt for a pit lane start. Ocon had qualified 18th amid brake issues, which he cited as impacting performance, but the disqualification was due solely to the rear wing infraction. The FIA stewards confirmed the car's non-compliance after verifying the measuring equipment and hearing from the team and technical delegates.
