The FIA has launched an investigation into Mercedes' movable front wing on its 2026 W17 car following a rival team's request for clarification after the Chinese Grand Prix. The wing allegedly closes in two phases, with the second exceeding the 400-millisecond regulatory limit. Officials aim to resolve the issue before the upcoming Suzuka Grand Prix.
Mercedes' W17 car is under FIA scrutiny for its front wing actuators, which operate in a two-phase manner. After teams submitted their active aerodynamics designs post-Chinese Grand Prix, a rival team—initially reported as Ferrari but denied by the Scuderia—sought regulatory clarification on the Silver Arrows' setup, according to information obtained by Motorsport.com. The wing's first closing phase meets the 400-millisecond limit monitored by sensors, but a second command fully closes the elements, surpassing that threshold. Video evidence circulating online demonstrates the system's activation, which is said to mitigate sudden forward load transfer before braking, aiding corner entry balance. The controversy shifts focus from prior power unit compression ratio issues, set for stricter enforcement from June 1. FIA single-seater technical director Nikolas Tombazis and his team are handling the matter, with a decision expected ahead of this weekend's Japanese Grand Prix at Suzuka to avoid escalating tensions. Mercedes showcased the wing in special livery during recent testing.
