Ferrari raised a few eyebrows in the F1 paddock in Bahrain on Thursday by unveiling a radical new rear wing concept on its SF-26.
The innovation, tested in the morning session by Lewis Hamilton, could redefine how active aero is exploited on the straights – and the intrigue lies in just how extreme the approach is.
At first glance, the wing appeared conventional, with the familiar upper element seemingly intact, nut with no central actuator. But the magic emerged once Hamilton hit the straights.
Unlike conventional designs, which flatten the upper flap to reduce drag, Ferrari’s solution rotates the element further by 180° – until it is literally upside down! On braking for corners, the wing promptly returns to its normal, downforce-generating position.
The Upside-Down Advantage
The concept is deceptively simple. By flipping the wing in straight mode, Ferrari aims to dramatically cut aerodynamic drag and potentially even produce lift, while simultaneously reducing rolling resistance on the tyres.
Combined, these effects could deliver a noticeable top-speed boost – a critical asset in a season where energy efficiency and battery management are under the microscope.
You spin me right round!

Crucially, the design remains within the 2026 regulations. There is no limit on how far an active aero flap can rotate back in straight mode, so long as the transition between straight and corner positions des not exceed 400 milliseconds.
This gives Ferrari leeway to push the wing into uncharted territory, something other teams are unlikely to have explored in such an extreme fashion.
Part of a Broader Aero Puzzle
Sources suggest the wing is one piece of a broader aerodynamic strategy. Ferrari’s innovative exhaust wing, revealed on Wednesday, extends the diffuser and channels exhaust gases over the rear wing.
While boosting downforce, it may introduce extra drag – making the upside-down wing’s straight-line efficiency all the more valuable.
For now, the upside-down rear wing remains a test item. Whether it will make the SF-26’s race debut is uncertain, but its daring approach has already turned heads.
In a season defined by energy-conscious engineering, Ferrari may have found a clever way to marry downforce and efficiency – all while leaving the competition wondering how to respond.
