WHY MCLAREN HAVE NAMED THEIR ROTATING WING THE 'H-WING'

McLaren will debut their rotating rear wing at Monza this weekend, naming it the H-Wing after the Etihad branding on the endplate—the same logic that gave the 2010 F-duct its name from sponsor markings near the inlet.

The concept isn't new. Ferrari ran a rotating wing in pre-season, Red Bull brought theirs to Miami, and McLaren tested it in Hungary FP1. Now it's race-ready for the Italian GP, paired with minor aero updates and low-drag track-specific parts.

Monza's long straights reward drag reduction, but the chicanes and heavy braking zones demand stability. Energy management will be the hidden variable—teams harvesting and deploying at different points could create a yo-yo effect through the lap. Technical Director Neil Houldey says margins are tight enough that simulation accuracy and clean practice runs will separate the grid. McLaren believes more performance is still locked in the MCL40, with further upgrades planned beyond Monza.
