The FIA is set to introduce stricter regulations on wing flexibility in 2025, following growing concerns over teams exploiting aero-elasticity for performance gains.

Last season, flexible wings were a major talking point, not just due to McLaren’s so-called “mini-DRS” system but also because of the flexing of front wings across the grid.

According to AutoRacer.it, the FIA has decided to tighten its testing procedures despite previously stating that its current methods were sufficient.

From the Australian Grand Prix, stricter static tests will be used to check rear wings. A further clampdown on front wing flexibility will follow at the Spanish Grand Prix on 1 June, with new tests designed to limit how much they can move under aerodynamic forces.

“Following further analysis carried out by the FIA Single Seater Department after the conclusion of the 2024 season, we are committed to ensure that bodywork flexibility is no longer a point of contention for the 2025 season," the FIA told Motorsport.com.

"As part of this effort, we will be increasing the scope of rear wing tests from the start of the 2025 season, and additional front wing tests being introduced from the Spanish GP.

"This phased approach allows teams to adapt without the need to discard existing components unnecessarily. These adjustments are aimed at further refining our ability to monitor and enforce bodywork flexibility regulations, ensuring a level playing field for all competitors to promote fair and exciting racing.”

Reports from Motorsport.com suggest that the FIA will update technical directive TD018 to reinforce these rules and prevent teams from exploiting wing flexibility.

Although technical directives are not made public, Motorsport.com has revealed that the FIA is set reduce the allowed front wing flex from 15mm to 10mm.

The delay in implementing the rule until June is intended to give teams time to adjust without having to discard their existing front wings at the start of the 2025 season.

Flexible wings have helped teams balance their cars better in corners, reducing understeer in slow turns and oversteer in fast ones. The FIA’s new rules aim to make the competition fairer by limiting this advantage.
