The introduction of the present ruleset in 2022 introduced a seemingly prescriptive method to growing the rear wing, with the prevailing design pattern making a curved merging of the higher ingredient and mainplane into the rear wing endplate.
This was launched to cut back the turbulence produced by the rear wing; fewer uncovered edges supplied much less alternative to supply tip vortices, which the aerodynamicists may construct into the automotive’s wake to reinforce downforce technology.
A bigger low-pressure space behind the automotive, produced by the melding of the wing vortices and the diffuser exit, helped to spice up the acceleration of the underbody movement and produced extra downforce.
The 2022 guidelines governing the rear wing design tried to place a cease to this however has did not dampen the creativity of the engineers trying to extract extra efficiency from the wing.
AlphaTauri’s new wing appears to be probably the most excessive association seen to this point, and the higher flap has been virtually indifferent fully from the endplate to show the wing suggestions. The attachment factors to the mainplane have been moved barely inboard to retain that tip publicity, which is able to generate vortices because the high-pressure air on high tries to roll to the lower-pressure zone beneath.
It will enable it to extract extra downforce from the general rear wing meeting and try and hyperlink that to the efficacy of the beam wing and diffuser. The Hungaroring’s status as a Monaco-adjacent circuit close to downforce emphasises the significance of the improve.
The remainder of the sphere has experimented with the attachment factors with some making an attempt to show as a lot of the wing suggestions as doable, in their very own bids to chase further efficiency.

Aston Martin’s rear wing is arguably probably the most just like the AlphaTauri design, though the entrance nook of the highest flap doesn’t stay uncovered because it merges into the remainder of the wing physique.
Alfa Romeo’s rear wing encompasses a small attachment level bolstered by a metallic insert, however the wing tip has been extruded all the way down to develop a barely extra uncovered tip to generate an identical impact.
The FIA rules governing the rear wing states that “as soon as the Rear Wing Endplate Physique and Rear Wing Tip are totally outlined, they have to be joined to create one unified quantity with no remaining overlapping surfaces.”
In its pre-race technical notes, AlphaTauri acknowledged that “the rear wing tip modifications give an environment friendly enhance in loading of the wing components.”
The automotive additionally options different additions, together with a barely raised nostril and a brand new entrance wing, whereas the ground has additionally been redefined beneath the automotive in a bid to imbue the AT04 with extra downforce.
