Overview
- Less than ten days before the 11–13 September Grand Prix organisers report the 5.4 km, 22‑turn circuit and grandstands are largely finished and core safety and communications systems have been tested.
- The layout completed official on‑track validation with a July filming day and Formula 3 tests on 25–26 August that checked the surface, race control, medical response and recovery procedures.
- Residents and the Stop Fórmula 1 Madrid group recorded high noise readings during tests, prompting the city to promise acoustic screens, natural barriers and other mitigation steps to reduce disturbance.
- Police are investigating theft of cabling from site generators but organisers say the incident does not affect overall operations as final fan zones and hospitality are put in place.
- The build was awarded in April 2025 to a UTE led by Acciona and Eiffage for €83.2 million, and city officials estimate about 120,000 visitors, roughly 8,000 direct jobs and an economic impact near €450 million if the event retains attendees next year.
