McLaren has decided to set aside its rotating "H-wing" rear wing concept for the 2026 Formula 1® Spanish Grand Prix, opting instead for a more conventional rear wing setup tailored to the demands of the Madring circuit. This move follows the team's recent experimentation with the innovative aerodynamic device earlier in the season.
The "H-wing," McLaren's own interpretation of the rotating rear wing concept pioneered by Ferrari, operates by rotating 180 degrees between Corner Mode and Straight Mode to reduce drag on straights. McLaren first introduced the H-wing during practice sessions at the Hungarian Grand Prix, further tested it at Zandvoort, and ran it in the race at Monza. Despite the system functioning as designed, the team has chosen not to deploy it in Spain due to the high-downforce nature of the circuit.
Instead, McLaren will use the rear wing configuration introduced at Zandvoort, which features sculpted endplates better suited to the aerodynamic requirements of the Madring layout. The team has prioritized preparing the H-wing for the Monza race and plans to bring it back at the high-speed Baku street circuit later in the season. Additionally, McLaren is developing a higher downforce wing that incorporates the rotating actuator for future use.
AlphaTauri, another team that introduced a rotating rear wing at Monza, will also park its version of the device for the Spanish Grand Prix, with plans to reintroduce it later in the season. McLaren's drivers, Lando Norris and Oscar Piastri, enter the Spanish weekend with the team positioned strongly, having secured two recent race wins with Norris.
The "H-wing" name draws inspiration from the letter H found in the Etihad logo on the rear wing, continuing a naming tradition from McLaren's 2010 F-duct system. While the rotating wing concept aims to balance aerodynamic efficiency by reducing drag on straights without sacrificing cornering downforce, its deployment depends heavily on the characteristics of each circuit.
At the Madring circuit, known for its high-downforce demands, McLaren has opted for a setup that prioritizes cornering grip over straight-line speed gains. This strategic choice reflects the team's approach to adapting aerodynamic components to specific track requirements rather than relying solely on novel technology.
McLaren's decision to withhold the H-wing in Spain highlights the ongoing development and refinement process teams undertake when integrating new aerodynamic concepts. The rotating rear wing remains a promising innovation, but its application must align with the unique challenges posed by each race venue.
