The FIA intervenes following intense scrutiny of McLaren's controversial rear wing design, which rival teams claim breaches aerodynamic regulations.

Red Bull, with Ferrari's behind-the-scenes backing, lodged three protests with the FIA about McLaren's flexible rear wing used in Baku. The FIA reportedly suggested to McLaren that a good way forward would be to make some voluntary adjustments to the design for future races, a solution the team accepted.

F1’s regulations limit the amount of flexibility permitted, but teams try to find ways to maximize this to improve performance.
