The Mercedes front wing is now under FIA scrutiny over alleged two-phase system

The debate over Formula 1’s compression ratios may be heading toward closure, but Mercedes has once again found itself at the center of technical scrutiny. While the FIA is set to clamp down on the high-profile compression ratio loophole from 1 June, attention has now shifted away from the power unit and toward the aerodynamics of the team’s 2026 challenger.

Mercedes is understood to be under observation for a movable front wing concept described as operating in a so-called “two-phase” manner.

Video footage circulating online appears to show the activation sequence of the Mercedes system and the operation of this two-stage mechanism. If confirmed, this could represent a regulatory grey area that the FIA will now be required to assess.

Performance implications and regulatory response

The concept is believed to mitigate the sudden forward load transfer experienced just before braking, improving car balance during the critical phase of corner entry. In a regulation cycle where aerodynamic efficiency and stability are tightly controlled, such a refinement could carry meaningful performance benefits.

Initial reports from Italian publication Autoracer suggested Ferrari had requested clarification over the system. However, the Scuderia has denied making such an inquiry.

According to information available to Motorsport.com, the request is believed to have originated from another, as yet unnamed, team within the paddock. Further details are expected ahead of this weekend’s Japanese Grand Prix at Suzuka.

The matter now rests with the FIA’s technical department, led by single-seater director Nikolas Tombazis. With scrutiny intensifying, the Suzuka weekend is likely to prove decisive in determining whether Mercedes’ interpretation stands — or whether further regulatory intervention will be required to prevent escalating controversy.
