Overview
- Norris and Piastri were stripped of second and fourth after FIA measurements found their skid/underfloor thickness below the 9.00 mm minimum at multiple points.
- Reported readings included 8.88 mm and 8.93 mm on Norris’s car and 8.96 mm, 8.74 mm and 8.90 mm on Piastri’s, confirmed by rechecks using micrometers accurate to 0.001 mm in the presence of stewards and team representatives.
- The revised standings leave Max Verstappen 24 points behind Norris and level with Piastri, with a Sprint weekend in Qatar and the Abu Dhabi finale offering 58 points in total.
- McLaren said the breach was unintentional, citing unexpected high‑speed bouncing and limited dry practice data, issued an apology to its drivers, and opened an internal investigation.
- Stewards ruled disqualification mandatory under the technical regulations, consistent with similar 2025 cases for excessive underfloor wear involving Lewis Hamilton and Nico Hülkenberg.
