F1TECH: How did Alpine and Audi bring a completely new rear wing philosophy?

The introduction of Formula 1’s 2026 active‑aerodynamic regulations has already sparked a wave of creative engineering solutions, and two teams—Audi and Alpine—have emerged with particularly unconventional rear‑wing mechanisms.

Their contrasting interpretations of the new rules demonstrate how much freedom teams now have in designing DRS‑style systems that operate far beyond the traditional single‑flap concept.

Audi’s Central‑Pivot, Single‑Linkage Architecture

Audi’s rear wing stands out immediately due to its unusual rotation system. Instead of placing the pivot point near the upper or lower edge of the wing supports, the team has positioned it directly in the middle of the endplate structure. This central placement causes the flaps to rotate in a noticeably different pattern compared to rival designs, producing a distinctive aerodynamic effect when the wing enters its low‑drag mode.

Because of this geometry, the flaps open at an angle rather than in a uniform, horizontal motion. This angled rotation redirects the airflow in a different direction, altering how the air detaches from the wing and influencing the behaviour of the flow toward the beam wing and diffuser.

Audi has also chosen a mechanical layout that differs from the more common dual‑actuator systems used by other teams. Instead of two attachment points controlling both flaps, Audi uses a single linkage that drives only the upper flap.

The lower flap then follows passively, moving as a consequence of the upper flap’s rotation. This creates a more fluid, less constrained opening motion that gives the wing a unique aerodynamic signature.

The result is a rear wing that appears to force the airflow downward more aggressively when opened, due to the steep angle the flaps adopt in their low‑drag configuration. This behaviour could influence both drag reduction and rear‑end stability in ways that differ significantly from conventional DRS systems.

Alpine’s Reverse‑Acting Flap Mechanism

While Audi has pursued a central‑pivot, single‑linkage concept, Alpine has taken a completely different approach. Their rear wing operates by collapsing the trailing edge rather than rotating the leading edge. In practice, this means the rear portion of the flap folds downward while the front section remains fixed in place.

This reverse‑acting mechanism effectively extends the mainplane when the wing opens, changing how the wing sheds load and reducing drag in a manner that contrasts sharply with Audi’s angled‑flap design. The result is a low‑drag mode that alters the wing’s profile from the back rather than rotating the entire flap assembly.

A New Era of Active Aerodynamics

Both Audi and Alpine are taking full advantage of the expanded freedoms introduced for 2026. The new rules allow teams to incorporate moveable elements not only on the rear wing but also on the front wing, and these devices can be activated on every straight rather than only in designated DRS zones.

This shift transforms active aero from a simple overtaking aid into a full‑lap aerodynamic system that must balance drag reduction, energy deployment and cornering performance.

Audi’s angled, centrally pivoted flaps and Alpine’s reverse‑collapsing trailing edge represent two radically different philosophies in rear‑wing design.

Both teams are exploring the boundaries of what active aerodynamics can achieve under the new regulations, and their innovations suggest that the 2026 season may deliver one of the most technically diverse grids in modern Formula 1.
