Ahead of the Singapore Grand Prix, McLaren has announced plans to adjust their rear wing design after facing scrutiny from the FIA. This follows concerns raised during the team’s impressive performance at the Azerbaijan Grand Prix, where their MCL38’s rear wing exhibited unusual behavior. Specifically, the upper flap would lift at high speeds, mimicking a DRS effect without actually activating the system. While the wing initially passed all FIA tests and adhered to regulations, its unexpected advantage—reducing drag and enhancing speed while maintaining downforce—sparked controversy.
In a statement, McLaren confirmed their intention to make minor adjustments to the wing, emphasizing their commitment to compliance with FIA regulations. They expressed confidence that their wing design was legal but chose to proactively address the concerns to maintain fair competition. They also expect the FIA to discuss similar issues with other teams.
The modifications are set to debut at the Las Vegas Grand Prix, allowing McLaren to capitalize on their performance for now, especially as they currently lead the Constructors’ Standings.
Rob Marshall, McLaren’s Chief Designer, highlighted the ongoing communication between the team and the FIA. He noted that while all teams face scrutiny, being at the front intensifies the focus on their designs. He stressed that the team’s priority is to ensure compliance and clarity with the FIA on all car aspects.
This incident could lead to stricter regulatory reviews, similar to the scrutiny applied to front flexi-wings, indicating that the FIA may need to widen their oversight across the grid.
