“Maybe this time we will copy it”. – In this way Christian Horner admitted that his technicians had taken a close look at the solution introduced in Budapest by Aston Martin. The rear wing seen on the AMR22 at the Hungaroring circuit was able to replicate the upper extension of the endplate while respecting the minimum connecting radii imposed by the regulation.
The external vertical strip of the AMR22 extends upwards, but has a curvilinear outline precisely to ensure a geometry that respects the minimum connections. By doing so, the flows in the upper part of the aileron are contained by the endplate instead of ‘overturning’ towards the outside, stimulating the pressure increase along the upper surface of the flap which is the basis of the aerodynamic downforce generation.
An idea that therefore allowed the Aston Martin technicians to ‘dribble’ what seemed like a ban imposed by the new regulation, a solution that approved by the FIA just like the ‘copy’ of the Red Bull sidepods already seen in Barcelona.
Aston Martin expected copies of its rear wing at the latest in Singapore Grand Prix, which is the most downforce configurations on the calendar together with Mexico, but according to what could be seen in the paddock judging from the first photos of the rear wings published by the journalist Albert Fabrega, no team wanted to use part of the budget to making rear wings inspired by the solution introduced by Aston Martin.
It is likely that this solution will later be used by the competition in the 2023 projects, but for now no one seems to have wanted to revise their development plans to incorporate the idea exploited by Aston Martin to have more downforce through the rear wing.
