Article C3.18.2
Bodywork Flexibility General
Chapter: C3
In Simple Terms
F1 cars must have bodywork that doesn't flex too much when tested with a special device. The test device pushes down on the car's body at a specific location, and the car's panels can only bend a maximum of 15mm under normal pressure or 20mm if pushed to one side.
- Bodywork deflection limits are 15mm symmetrical load or 20mm single-side load
- Test device must weigh no more than 2kg with a flat surface
- Device is positioned 475mm from the car's centerline (Y=0) and 1100mm forward from reference point
- Rules prevent teams from using overly flexible bodywork for aerodynamic advantage
Official FIA Text
Load application devices must have flat top surface without recesses, apply full load to bodywork at test point, be placed with inner face 475mm from Y=0, forward face at XF=-1100, top face at Z=300, and have mass no more than 2kg. Vertical deflection must not exceed 15mm when load applied symmetrically or 20mm when applied to one side.
