The FIA has mandated McLaren to make modifications to the rear wing of their race car. This request comes after other teams expressed doubts about the legality of the design. The contentious part of the rear wing is allegedly capable of rotating under aerodynamic load, allowing for increased airflow at high speeds.
Scrutinizing the Flexible Wing
During an investigation into the wing’s operation, the FIA found that the construction complies with the statistical rules. However, the design raised questions after the Azerbaijan Grand Prix. While some deformation can naturally occur due to the forces exerted on the wing, it is not permissible to design components to specifically move under certain conditions.
Technical Directive TD34 and the McLaren Wing Controversy
In an existing technical directive known as TD34, the FIA has clearly indicated that parts should not intentionally move or deform due to influences such as temperature or aerodynamic load. This directive has recently raised questions about the McLaren wing.
The FIA’s Decision
Although the FIA has previously dismissed questions about flexible front wings, it is now compelled to intervene. This action is taken to prevent teams from further pushing the boundaries of the regulations. “Parts must always stay within the rules, even if they are flexible. The FIA must clearly determine what is and is not acceptable,” said one of the team bosses.
For now, McLaren is allowed to continue using the current version of the rear wing on circuits where it is effective. However, modifications will ensure that the part in question no longer exhibits the suspected flexibility. This provides some reassurance to the other teams, who trust that the FIA will enforce the regulations.
