FIA Implements Stricter Rear-Wing Flexibility Tests Ahead of Chinese GP
The FIA has announced stricter rear-wing flexibility tests for Formula 1 teams beginning with the Chinese Grand Prix, following previous concerns about bodywork flexing. While all cars complied with existing regulations in Melbourne, the FIA feels tougher tests are necessary. A new limit of 0.5mm for upper rear wing movement will be implemented, with a temporary allowance for the Shanghai race.
Formula 1 teams are set to undergo more stringent rear-wing flexibility tests at the forthcoming Chinese Grand Prix. This decision by the Fédération Internationale de l’Automobile (FIA) follows concerns raised during the 2025 season opener in Melbourne regarding excessive bodywork flexing observed in some teams’ rear wings. Following last year’s ‘mini-DRS’ controversy, which prompted McLaren to amend their design, the FIA announced new load tests to ensure stricter compliance starting this weekend.
The FIA had previously introduced new deflection limits for rear wings during the Melbourne race. As additional scrutiny arose around rear-wing flexing during pre-season testing, they implemented extra monitoring measures at Albert Park, including the installation of cameras to observe on-track deformations. Upon reviewing the data, the FIA determined that tougher tests were justified moving forward from the Chinese GP, which is the second round of the season.
In a statement released on Monday, the FIA acknowledged the successful compliance of all cars during the Melbourne event. However, they signaled the need for a revised limit on upper rear wing movement starting from the Shanghai race. Specifically, new regulations dictate that a maximum variation of 2mm in the ‘slot gap’ of the rear wing will be imposed under a specified load, which will be further reduced to 0.5mm in the future.
The heightened rear-wing flexibility tests signify the FIA’s commitment to maintaining competitive fairness and safety in Formula 1. As teams prepare for a fresh wave of challenges, compliance with the new regulations will be closely monitored, starting from the upcoming Chinese Grand Prix. This initiative underscores the importance of technological integrity within the sport as it continually evolves.
