Floor Body Extrusion

Chapter: APPENDIX C2: REGULATION VOLUMES

In Simple Terms

The floor of the car (the flat bottom surface) must extend upward to a specific height of 275mm. Think of it like taking a 2D shape and stretching it vertically to create a 3D wall - this defines how tall the floor structure can be.

  • The floor surface defined in the previous regulation must be extended vertically (along the Z-axis)
  • The maximum height of this extrusion is set at 275mm from the reference plane
  • This measurement is crucial for determining the overall floor dimensions and aerodynamic compliance
  • Any deviation from this specification could violate technical regulations
Official FIA Text

Once the surface in §4.1 is fully defined, it must be extruded along Z to Z = 275.
