Cockpit floor test

Chapter: C13.4

In Simple Terms

The cockpit floor (where the driver sits) must be strong enough to withstand a heavy downward force of 75,000 Newtons (roughly 7.6 tons) applied to a specific point. After this test, the floor can only bend slightly—less than 3mm—and must not crack or break.

  • A 200mm circular pad applies 75kN of downward force to the cockpit floor
  • The structure must not fail or break under this extreme load
  • Permanent deformation must be less than 3mm after the 1-minute test
  • This ensures the cockpit remains rigid and safe during impacts and crashes
Official FIA Text

A 200mm diameter pad placed beneath Survival Cell at [XC,Y]=[-600,0]. 75kN vertical upward load applied. No structural failure permitted, permanent deformation <3mm after 1 minute.
