Controversial Rear Wing Sparks Debate Ahead of Abu Dhabi Finale

Red Bull’s Technical Director Pierre Wache has reignited criticism of McLaren’s flexible rear wing, a contentious innovation used earlier in the 2024 Formula 1 season. Despite McLaren removing the design following an agreement with the FIA, Wache remains unhappy about the advantage it provided, particularly at key circuits like Baku and Monza.

The saga highlights ongoing challenges in regulating technical ingenuity in a sport where innovation often flirts with the boundaries of legality.

A Victory Under Scrutiny

McLaren’s flexi-rear wing came under fire after Oscar Piastri’s victory in Baku, where the MCL38’s uppermost rear wing plane was observed flexing under high-speed conditions. This movement, Wache argues, created a DRS-like effect, boosting McLaren’s straight-line speed and handing them a significant advantage.

“Without that, Baku, they will not win. Even our constructors’ championship will be completely different,” Wache told Racing News 365.

Red Bull’s frustrations are compounded by the fact that McLaren’s 21-point lead over Ferrari in the Constructors’ Championship—heading into the Abu Dhabi finale—was built, in part, on results from races where the flexi-rear wing was deployed.

Regulation Grey Areas

While McLaren complied with the FIA’s demand to remove the rear wing design, Wache is critical of the oversight that allowed it to race in the first place. “Some grey areas are so attractive as an engineer,” Wache said, “but when you see the rear wing of McLaren, I’m sorry, but it’s more than grey.”

F1’s technical regulations require teams to prove the legality of their designs. Wache compared the situation to speed checks, where enforcement depends on being observed at specific points. “When the police doesn’t see it, it doesn’t mean it’s legal,” he said.

A History of Controversy

Wache also referenced past controversies, including Ferrari’s disputed power unit design, to illustrate how exploiting technical loopholes can disrupt competition. “What happened to Ferrari in the past… that was more than the limit. It’s frustrating for us when the police doesn’t do their job.”

Despite his frustrations, Wache acknowledged that bending the rules is “part of the game” in Formula 1, adding, “A good idea is a good idea, but when it’s over the playing field, it’s not correct.”

McLaren’s Defense and a Level Playing Field

McLaren has defended its innovation as being within the rules at the time of use. However, the incident has intensified calls for stricter enforcement of technical regulations to ensure fair competition.

As Red Bull reflects on a season where constructors’ championship hopes faded early, the flexi-rear wing controversy serves as a reminder of how fine the line can be between innovation and infringement.

What’s Next for F1 Regulations?

Heading into 2025, the FIA faces renewed scrutiny over its ability to police Formula 1’s ever-evolving technological landscape. With teams pushing boundaries to gain even the smallest advantage, ensuring a consistent and fair application of rules will be critical to maintaining the sport’s integrity.

For now, Red Bull will have to settle for watching McLaren and Ferrari fight for the Constructors’ Championship—and ponder what might have been if every team had played strictly within the “playing field.”
