How Formula 1 Parc Ferme Works Explainer
Parc ferme is the controlled rules state that limits work on a Formula 1 car around qualifying and the race. It preserves the setup on which the car qualified and lets FIA scrutineers verify that teams do not transform the car for different conditions afterward.
While the car is under parc-ferme conditions, teams cannot freely alter suspension setup or aerodynamic configuration. Regulations permit specified routine work, safety changes, and replacements approved by the technical delegate, with replaced parts documented and required to match the permitted specification.
The restriction is a rules condition as well as a secured physical area. It can apply while cars are in team garages, where assigned oversight and cameras help monitor work. After sessions, selected cars may also be taken directly to the FIA's formal parc-ferme area for checks.
A prohibited setup change can force the driver to start from the pit lane, with details depending on the competition format and timing of the breach. Teams sometimes accept that penalty to adapt a poorly handling car. Viewers should distinguish authorized repairs from performance-driven reconfiguration.
No. It is also a regulatory condition that restricts work while cars may still be in their garages.
Specified work and approved like-for-like replacements are allowed under FIA supervision.
The driver may be required to start the race or sprint from the pit lane.
