System 1’s 2026 technical rules are pushing groups to maximise aerodynamic effectivity, favoring revolutionary options.

Audi has labored on this entrance and adjusted its philosophy from the Barcelona shakedown: its rear wing flap now goes down like Alpine’s.
The hybrid-imposed power administration limitations have made aerodynamic effectivity a key space, with the brand new guidelines granting engineers higher freedom in design, significantly concerning energetic aerodynamics, which is used on nearly each straight. This contributes to decreasing drag on the straights, and consequently power consumption.
A number of rear wing configurations have been noticed in pre-season testing. is a chief instance, as a brand new idea that pushes the bounds of creativeness. It’s the most excessive interpretation of the principles to date, however different attention-grabbing options embrace Alpine’s, with the wing rotating on the vanguard, and Audi’s, which initially opened obliquely.

Alpine was the primary crew to take a very new conceptual path in comparison with what DRS was allowed to be, pushing different squads to rigorously consider its advantages and limitations.
Audi adopted this resolution through the second week of the Sakhir check, tweaking the actuator that controls the cell wing.
In Audi’s unique idea, the system raised the primary component, whereas the second remained passive and adopted the principle flap’s motion. Now, equally to Alpine, the opening happens in the other way: the actuator acts on the second component, pushing it downward, whereas the primary stays passive.

This was made attainable by the wing rotation pivot being positioned on the primary flap, not the second – even on the preliminary idea. Thus, the best way the wing opens might be tweaked.

This resolution presents some aerodynamic benefits, notably within the transition section, guaranteeing higher stability in early braking, but it surely additionally introduces important challenges that groups should rigorously handle.
Whereas the DRS opened at comparatively low velocity and returned to its preliminary place beneath the strain of air, Alpine’s and Audi’s rear wing experiences the alternative scenario. The actuator should exert considerably higher effort to beat drag and transfer the flap.
Commercial
Alpine’s resolution is sort of advanced, with a number of attachment factors, whereas Audi’s seems easier, based mostly on a single attachment to the higher flap. An attention-grabbing selection, which as soon as once more reveals how the 2026 guidelines are stimulating engineers’ creativity.
