Reference Volumes and Surfaces

In Simple Terms

F1 cars must fit within specific three-dimensional spaces and shapes defined by the rulebook. These 'reference volumes' are like invisible boxes and surfaces mapped out around the car using a standardized coordinate system, and the FIA uses them throughout the regulations to check if cars are legal.

• Reference Volumes and Surfaces are predefined 3D spaces and geometric shapes that cars must comply with
• They are defined in Appendix C2 using the Car Coordinate System as a standard measurement reference
• These constraints are used throughout F1 regulations to verify car legality in areas like aerodynamics, chassis dimensions, and component placement
• The system ensures fair competition by providing objective, measurable standards for car design
