Following Oscar Piastri's victory at the Azerbaijan Grand Prix, questions have arisen regarding the legality of McLaren's rear wing, which some observers likened to a 'mini-DRS' due to its unique flexing design that appears to reduce drag at high speeds. The FIA is currently reviewing data and additional evidence related to this issue, having previously cleared McLaren of any infractions regarding their front wing. While McLaren insists their wing passed all deflection tests, rival teams are pushing for clarification on the design's compliance with regulations. The FIA reserves the right to mandate modifications during the season if deemed necessary. As the situation unfolds, McLaren's position in the Constructors' Championship has improved significantly, raising the stakes in upcoming races. Meanwhile, team principal Christian Horner of Red Bull emphasized that it is up to the FIA to provide guidelines on flexible wings.
