McLaren parks H-wing in Madrid: the rotating rear wing will return in Baku

McLaren will put its rotating H-wing concept on hold for this weekend’s Spanish Grand Prix in Madrid, with the system scheduled to return at the high-speed Baku street circuit later in the season.

McLaren’s system, internally known as the H-Wing, endured a delayed rollout before debuting in practice at the Hungarian Grand Prix. It was tested again at Zandvoort before making its competitive appearance at last weekend’s Italian Grand Prix. The system worked as intended at Monza, helping the car improve its efficiency on the straights.

The technical decision now facing McLaren is not whether the concept works, but where it delivers enough performance to justify further production effort. The team will retain the H-wing on its low-drag rear wing rather than retrofitting the mechanism to its existing higher-downforce packages.

No H-wing for Madrid’s higher-downforce configuration

Madrid’s new Madring circuit requires a higher-downforce approach, and McLaren is set to use the rear wing introduced at Zandvoort. That specification features heavily sculpted endplates, but it will not include the rotating actuator.

With production resources requiring careful allocation, McLaren chose to fast-track its H-wing development for Monza, where the potential benefit from drag reduction was considered significantly greater than at twistier circuits. As a result, it did not produce a Zandvoort-style higher-downforce wing fitted with the system.

The Monza specification is expected to return at Baku, another venue where top speed and aerodynamic efficiency carry greater importance. McLaren also plans to introduce a later higher-downforce iteration built from the outset around the rotating rear-wing actuator.

A name with McLaren history

The H-wing name refers to the letter H in the Etihad logo on the rear wing of the MCL40. That letter sits along the centreline, where the Straight Mode actuator is positioned. The naming follows the tradition of McLaren’s F-duct from 2010, which took its name from the Vodafone branding near its installation point.

McLaren arrives in Madrid among the favourites after Lando Norris won at both the Hungaroring and Zandvoort. For more on the technical and sporting questions surrounding the venue, see our 2026 Spanish Grand Prix preview.

Racing Bulls, which introduced its own rotating rear wing at Monza, is also expected to park the system in Madrid because it does not suit the circuit’s characteristics. Its wing is planned to return later in the season.
