McLaren Explains Why Its 'Macarena' Rear Wing Never Turned a Wheel in Austria

The wing that never ran

McLaren arrived at the Red Bull Ring for the 2026 Austrian Grand Prix carrying an experimental rear wing it had planned to trial on Lando Norris's car during Friday practice, but the component never turned a wheel in anger. ^[3] Oscar Piastri confirmed ahead of the weekend that the part was a test item only, with no intention to race it at this stage. ^[3]

The wing is McLaren's interpretation of the so-called 'Macarena' or 'flip-flop' design, which rotates the top flap upside down so that it closes when the brakes are applied at the end of a straight. ^[1] Ferrari pioneered the concept during pre-season testing and introduced it in race conditions for the first time in Miami; Red Bull subsequently produced their own variant. ^[1] McLaren's arrival in Austria made the Woking squad the latest team to pursue the technology. ^[6]

What went wrong in the garage

The experimental wing did not reach the track because it failed the team's own internal checks before free practice began. ^[2] McLaren's Friday debrief noted that "during final sign-off tests in the garage, it didn't perform as expected," and that "the correct decision was to focus our track time on optimising the" remainder of the car's setup. ^[2] Norris also encountered a hydraulic leak in FP1 that restricted his running, compounding a difficult day for the team. ^[2]

A McLaren spokesperson subsequently confirmed that there were no plans to refit the wing for any remaining session at the Red Bull Ring, meaning it will only return at a later event. ^[4] The-Race reported that teething problems caused the squad to remove the part before it had run even a single lap in practice. ^[4]

:::analysis McLaren's decision to prioritise track time over an untested component is consistent with where the team sits in the 2026 competitive order. Norris himself acknowledged the squad is roughly two to three months behind its rivals in development terms, which makes every practice lap valuable for correlation rather than exploration. Deferring the wing to a future round rather than forcing it onto the car under pressure reflects a measured approach, even if the delay means rivals accumulate more data on similar technology in the meantime.

Context: a wider development race

The 'Macarena' architecture has become one of the defining aerodynamic battlegrounds of the 2026 rules cycle. ^[1] Under the new regulations, teams have pushed hard to find drag-reduction gains on straights while preserving downforce through corners, and the rotating rear wing addresses that trade-off directly. ^[1] Neil Houldey, McLaren's Technical Director of Applied Engineering, described Austria as "historically a strong track" for the team and pointed to the rear-wing trial as part of a package of minor detail refinements to the MCL40's rear corners. ^[7]

With the wing now shelved until a future round, McLaren's development timeline extends further into the second half of the season, where the gap to the front is expected to close as factory-built upgrades arrive. ^[8]
