Parc Ferme Conditions
Chapter: Chapter III - Parc Ferme
In Simple Terms
Parc Ferme "locks" the car setup after qualifying begins. Teams cannot make significant changes between qualifying and the race - this ensures the car you qualify with is essentially the same car you race. Only limited repairs and minor adjustments (like front wing angle) are allowed.
- Starts when car first leaves pits for qualifying
- Setup changes locked until race start
- Only specific minor work permitted
- Breaking parc ferme = pit lane start penalty
Official FIA Text
Each car will be deemed to be in parc ferme from the time at which it leaves the pit lane for the first time during qualifying until the start of the race. During this period, no operation may be performed on a car except for specific permitted work as detailed in these regulations.
