Why McLaren’s new H-wing could be crucial in the Italian Grand Prix battle

The Woking-based squad has named the device the H-wing. It is designed for the low-drag demands of the Temple of Speed, where outright efficiency on Monza’s long straights are crucial.

The concept follows the rotating rear-wing designs already seen elsewhere on the grid. Rather than relying only on a conventional opening and closing movement, the upper flap rotates through 180 degrees as the car switches between cornering and straight-line configurations. Ferrari first trialled the concept in Bahrain testing before racing it in Miami, while Red Bull also introduced its own version at that event.

McLaren had initially targeted the Austrian Grand Prix for its own debut. However, the team elected not to run the part after its final checks raised concerns about whether it was ready for the opening practice session. The design returned for further work before an updated version was tested in Hungary, where McLaren received encouraging feedback.

Technical director for engineering Neil Houldey has now confirmed that the package is ready to be assessed in competitive conditions at Monza.

Alongside the H-wing, McLaren has brought a fresh low-drag rear-wing specification and further small aerodynamic options. The team will use practice to evaluate the components before settling on its qualifying configuration.

McLaren arrive in Italy on a strong run of form after Lando Norris won the Hungarian and Dutch Grands Prix. Yet Monza represents a markedly different test to the previous two venues, meaning recent results cannot be treated as a reliable guide to the order this weekend.

The Italian circuit combines extended full-throttle sections with major braking zones and slow chicanes. That puts an emphasis not only on trimming drag but also on braking stability, ride quality and energy management.

McLaren believe further performance remains available from both extracting more from its current package and bringing additional developments later in the season. But with competition at the front tight, the team’s immediate task is clear: make the new H-wing work, execute cleanly through practice and give Norris and Oscar Piastri the best possible platform to challenge at Monza.
