Albert Park Circuit

Revised to comply with 2026 regulations.

Mandated to be supported on two pylons intersecting the underside of the mainplane. One or two element flap assembly actuating to engage SM and reduce drag. Chord length of the mainplane is to team design and the endplates have returned to be perpendicular panels at the ends of the elements. ORBR design places the actuator on centreline.

Three-element active rear wing Key aspect for this new era has been on developing a top rear wing solution around a three-element arrangement without relying on interactions with the lower beam wing, which was a dominant factor with the 2025 topology. Given the importance of SM mode in 2026, maximizing SM effect has been a point of focus

The 2026 Technical Regulations allow for a three‑element upper Rear Wing configuration within a reduced legality volume compared to previous seasons.

Haas employs a three-element upper rear-wing assembly, with the SM mechanism providing simultaneous actuation of both flap elements. The mainplane is configured with a relatively low camber, while the flap cluster adopts an aggressive geometry to maximise downforce generation in Corner Mode (CM). In Straight Mode (SM), the system targets a substantial drag reduction by unloading the flap pair and exploiting the flat mainplane to minimise pressure-drag contribution

Three element rear wing with the pylons mounted to the lower surface of the first element.

The rwd two elements are activated in SM mode, reducing their incidence. In CM the rear wing is optimised to provide maximum load while remaining stable and consistent. The SM deployment angle is defined to reduce drag as much as possible.

Compared to the 2026 starting point, the R01 rear wing has increased camber.

Increased rear wing camber to increase wing load, with the chord of the elements optimised to find the right balance between SLM closed Cz and SLM open Cx.

Complete new rear wing design in accordance with the 2026 regulations With no beam wing in 2026, and new regulations allowing the rear wing to be in Straight Mode in most of the straight lines, the rear wing was completely redesigned to ensure load is generated without any local flow field instabilities.

New Rear Wing

A new Rear Wing geometry featuring revised mainplane and flap elements, gaining aerodynamic load throughout all conditions while maintaining efficiency.

Updated design with revised flap loading.

Improved yaw characteristics whilst being designed to maximise aerodynamic load when cornering and maximise the drag reduction when SLM is active.
