Overview
- During final practice at the São Paulo Grand Prix, Perez was seen ejecting a small plastic cable organiser from his Cadillac and later told his race engineer he thought it was a radio cable box.
- Team radio captures show race engineer Carlo Pasetti acknowledged the report and said the team would investigate the item that came off the car.
- The FIA summoned Perez to the Formula 1 stewards, who reviewed in‑car footage and handed him a formal warning for throwing the object on track as inappropriate.
- Separately, Cadillac fitted new power‑unit components to Perez’s car and confirmed he will start the race from the back of the grid, with Perez having been 20th fastest in FP3.
- The stewards’ action underscores how FIA safety rules treat any object thrown from a car as a risk to drivers and marshals, and teams now face scrutiny of cockpit fittings and on‑team procedures.
