F1 technical analysis: Ferrari’s innovative SF-26 movable wing leaves paddock speechless. Ferrari tests a groundbreaking SF-26 movable rear wing at Bahrain 2.

On Day 2 of the Bahrain 2 tests, Ferrari’s SF-26 stunned the paddock. The new movable rear wing tested by the Prancing Horse offers an innovative approach. Let’s take a closer look at the solution trialed on the SF-26 during the second day of testing.

F1 2026: innovations in movable flap operation

Alpine was the first team to introduce an innovative movable rear wing. With the A526, the French squad adopted a completely new rotation system: in Straight Mode, the movable flap rotates around the leading edge rather than the trailing edge. Traditionally, the flap would lift the rear edge upwards when opening, then push it down when closing. On the A526, the opposite occurs: the flap rotates around a hinge near the leading edge, so in Straight Mode, the trailing edge moves down instead of up.

This Alpine solution has drawn significant attention in the paddock. By minimizing the frontal area, drag is reduced to a minimum. On other teams, opening the movable flap created a channel with the main plane, but Alpine’s design eliminates that channel, freeing up the main wing’s area. Additionally, the system can improve braking performance: air reattaches faster after flap closure, allowing Alpine drivers to brake later than rivals.

Ferrari’s movable wing rotates 270°!

Following Alpine’s lead, Audi also introduced an innovative wing similar to the French team’s concept. Most other teams have retained the traditional DRS system used in previous years. However, on Day 2 of Bahrain 2 testing, Ferrari unveiled its solution. The SF-26’s movable flap rotates a full 270°. Pressing the active aerodynamics button sends a signal to the actuator, rotating the flap 90° in the conventional manner (stages 1-2 in the image below), plus an additional 180°. The normally lower-facing section of the wing becomes the top surface, while the top-facing section rotates downward.

The concept behind Ferrari’s new flap remains familiar: reduce drag and increase rear-end efficiency. Such a rotation requires a complete redesign of the rear wing structure. The extra 180° would be impossible with a traditional system, so the central actuator is removed. It’s likely the flap actuators are now integrated into the wing endplates, which also changes the actuator’s circuit and mounting points. The pivot, around which the flap rotates, has moved from the trailing edge to the center of the flap.

FIA approval and technical benefits

Ferrari’s solution has already been approved by the FIA. The 2026 F1 technical regulations do not check wing clearance during rotation—only at fully open and fully closed positions—allowing the 270° rotation. The potential lap time advantage is still uncertain, but the theoretical benefits are clear. Flipping the flap reduces drag while altering airflow management and the fundamental behavior of the rear wing. In Straight Mode, the wing can even generate lift at the rear, lowering downforce and increasing top speed on straights while restoring full downforce in corners.

Moreover, there may be a braking advantage: during rotation, the flap becomes perpendicular to the ground momentarily, significantly increasing the frontal area. The active aerodynamics can therefore act as an instant airbrake, loading the rear axle briefly.

Bold approach on track

It’s unclear whether Ferrari achieved all expected results on Day 2, but what is certain is the team entered the track with bold solutions and a clear vision. The SF-26’s movable wing demonstrates Ferrari’s willingness to innovate and push the limits of aerodynamics in the new 2026 F1 era.
