FIA issues stringent crackdown on sneaky flexi-wing tactics of Formula One teams
FIA issues a fresh TD018 soon after the Dutch GP that will ensure teams cannot exploit the flexi wings

The FIA is tightening the screws on flexible wings, announcing a fresh clampdown to kick in immediately after the Italian Grand Prix. This move comes after ongoing concerns that some teams have been exploiting loopholes in the regulations regarding flexi wings. The FIA’s Technical Directive TD018, issued this year, aims to address these issues head-on and maintain a level playing field in Formula 1.
TD018, unveiled just ahead of the Dutch GP, was first reported by Motorsports.com, shines a spotlight on a practice in which teams have sought to gain an unfair advantage by allowing certain components to flex, thereby enhancing aerodynamic performance. Such practices have raised eyebrows in the F1 community, prompting the FIA to take action.
The FIA’s decision is rooted in the belief that teams have been employing complex mechanisms to flex their wings in ways that traditional load tests cannot detect. As a result, the FIA has taken a comprehensive approach, outlining specific design elements that are now considered rule violations. Teams must submit all relevant drawings depicting their wing designs by September 8th.
Article 3.2.2 of the F1 regulations explicitly mandates that “the aerodynamic influence of any component of the car not considered to be bodywork must be incidental to its main function. Any design which aims to maximise such an aerodynamic influence is prohibited.” Any deviation from these rules is now firmly in the FIA’s crosshairs.
Teams will be required to submit assembly drawings to the FIA before the race

The impact of these clampdowns on teams has already been felt, with Aston Martin experiencing a notable decline in performance following the FIA’s intervention. The team had been using a ‘flexi-wing’ innovation that allowed them to manipulate airflow over the wing, reducing drag on straightaways and increasing top speed. However, this design was deemed to contravene F1 regulations.
In response to these developments, the FIA demands greater transparency from teams. They must now submit detailed assembly drawings and cross-sections showcasing how wing elements are affixed to various car parts. This enhanced scrutiny aims to ensure compliance and prevent further rule violations.
The FIA’s proactive stance reflects its commitment to preserving the integrity of the sport. These measures are not only about enforcing the rules but also about maintaining fairness among competitors. With the ongoing scrutiny and the upcoming implementation of TD018 after the Italian GP, teams will need to adapt and ensure that their designs adhere to the new, stricter regulations.
