FIA reports that half of the grid implemented flexi-wing modifications.

      The most notable adjustments for Alpine and Haas F1

      A significant portion of the Formula 1 grid had to implement rear wing adjustments due to a further FIA crackdown on excessive flexibility that took effect from the Shanghai race. Some teams, like McLaren—accused of cleverly designing their wings to pass FIA tests while creating a 'mini DRS' effect at high speeds—claimed that no changes were necessary following the Chinese Grand Prix. However, reports indicated that Alpine and Haas made the most substantial modifications.

      FIA single-seater director Nikolas Tombazis stated, "Four out of five teams had cars that did not comply with the new standards." In China, the FIA mandated the installation of high-definition cameras on all cars during free practice to assess flexibility beyond static scrutineering tests. "There are no remaining questions at this point," Tombazis remarked, "but we will keep using cameras. We combine the results of load tests and camera data to ensure we don’t overlook any tricks. Currently, the FIA is satisfied with the teams' efforts to restrict rear wing flex.

      Nonetheless, we recognize that teams are continuously seeking to optimize their cars, and we must stay alert. Our perspective is that a car passing FIA tests is usually compliant, unless it contains hidden mechanisms or relies on non-linear material properties, temperature, or similar factors. In such instances, we take action."
