Article C3.18.10
Rear Wing Bodywork Flexibility
Chapter: C3
In Simple Terms
The rear wing must be rigid and can't bend more than 6mm or twist more than 1 degree when the FIA applies heavy downward forces to test its strength. This rule ensures teams can't use flexy wings to gain an unfair aerodynamic advantage.
- Maximum 6mm deflection along the loading axis when test forces are applied
- Maximum 1.0° angular twist in the Y-Plane (side-to-side rotation)
- Tests use two 985N downward loads applied to specific points on the rear wing profiles
- Ensures fair competition by preventing flexible bodywork from providing aerodynamic benefits
Official FIA Text
Bodywork may not deflect more than 6mm along loading axis and 1.0° in Y-Plane when two loads of [218, 0, -985]N each applied to Rear Wing Profiles at [XR=390, ±325, 835]. Loads applied through adaptors between 275-375mm from Y=0. Angular deflection measured at [XR, Y][375, ±450].
