Floor Corner

Chapter: C3

In Simple Terms

This rule allows teams to add special corner bodywork at the floor edges that doesn't have to follow normal floor restrictions. However, this corner piece must fit within a defined boundary zone and can only have a limited number of sections or layers in different directions—up to 3 sections going front-to-back, 4 sections going side-to-side, and 2 sections going up-and-down.

  • Floor corner bodywork gets an exemption from standard floor rules but must stay within the RV-FLOOR-CORNER boundary
  • Maximum complexity is 3 sections in the X-direction (front-to-back), 4 in the Y-direction (side-to-side), and 2 in the Z-direction (up-and-down)
  • This controlled flexibility allows aerodynamic optimization at the floor corners while preventing unrestricted complexity
Official FIA Text

Floor Corner Bodywork exempt from Article C3.2.4, must lie entirely within RV-FLOOR-CORNER, have up to 3 sections in any X-Plane, up to 4 sections in any Y-Plane, and up to 2 sections in any Z-Plane.
