FIA enforces tougher 10mm front wing flex limit from Spanish Grand Prix onwards

From the Spanish Grand Prix onwards, the FIA has tightened the front wing flex limit in Formula 1, reducing the allowable deflection from 15mm to 10mm under aerodynamic load, as per Article 3.15.4 of the technical regulations.

This move aims to curb the aerodynamic advantages teams gain by engineering controlled wing flex, which can reduce drag and improve top speeds. Aero-elasticity has long been exploited, with teams designing wings to flex strategically, impacting performance.

"It's a significant change," said Red Bull boss Christian Horner. "There will be some effect and, of course, the teams have anticipated this so it may well be neutral. Or it may affect tyre degradation. It doesn't make life easier!"

Ferrari's Fred Vasseur called the change a "game-changer for everybody because we don't know the impact on every team." Mercedes team principal Toto Wolff added that the directive adds "another level of intrigue" to the season, noting that some teams, like Ferrari, may have exploited flexible front wings less than others.

Last year, controversy surrounded rear wing flexing, prompting the FIA to introduce stricter tests and monitoring, including high-definition onboard cameras. This new front wing directive continues the FIA's efforts to ensure aerodynamic fairness.

Red Bull has publicly challenged McLaren over wing flexibility, though McLaren's MCL39 has passed all existing tests. The new limit may impact team strategies and car setups as the season progresses.

With 16 races remaining, the updated front wing flex limit is expected to influence aerodynamic performance, tyre wear, and competitive dynamics across the grid.

This technical directive underscores the FIA's ongoing commitment to regulating aero-elasticity and maintaining competitive balance in Formula 1.

From the Spanish Grand Prix onwards, the FIA enforces a stricter 10mm front wing flex limit, down from 15mm, aiming to curb aerodynamic advantages from wing flexing. Teams anticipate varied impacts on performance and tyre wear, with leaders like Red Bull and Ferrari calling it a potential game-changer.
