McLaren parks H-wing for Madrid, brings it back for Baku

McLaren is parking its H-wing concept for this weekend's Spanish Grand Prix in Madrid, with the rotating rear wing set to return in Baku. The system debuted in competition at Monza and worked as intended, but it won't be retrofitted to higher downforce packages yet.

Why it matters:

The decision highlights the strategic trade-offs teams face with limited production resources. The H-wing, which rotates 180 degrees between Corner Mode and Straight Mode, delivers its biggest laptime benefit on low-drag, high-speed circuits like Monza and Baku. Prioritizing those tracks maximizes its impact.

The details:

• McLaren's H-wing, named after the H in the Etihad logo, was pioneered by Ferrari and first seen in winter testing.
• After a delayed rollout, it appeared in Hungary practice, was tested again in Zandvoort, and ran in competition at Monza.
• The system reduced drag on straights as intended, but McLaren will keep it on its low-drag wing for now.
• For Madrid's high-downforce Madring circuit, the team will run the Zandvoort wing with sculpted endplates, without the H-wing.
• Producing a version of that wing with the H-wing was deemed not worth it, as drag reduction yields a much smaller laptime benefit on twistier circuits.
• The Monza H-wing returns at Baku at the end of September, another high-speed street circuit.
• A future higher downforce wing, built from the ground up with the rotating actuator, is also planned.

Between the lines:

The H-wing name follows a tradition set by McLaren's famed F-duct in 2010, named after the F in Vodafone. The letter H runs along the centreline of the MCL40's rear wing, where the straight mode actuator sits.

What's next:

McLaren heads into Madrid as one of the favourites after two wins for Lando Norris at the Hungaroring and Zandvoort. The H-wing's return in Baku will be a key test of its effectiveness on another high-speed layout.
