The Formula 1 teams participating in the Saudi Arabian Grand Prix have had to find new ways to improve performance while adhering to the cost cap and resource restrictions in place. For instance, Mercedes has made some alterations to its rear wing to better suit the demands of the Jeddah street track. The upper rear corner of the endplate has been relieved of its cutout, and the tip section of the endplate has been trimmed down, giving the wing a new behaviour. The car also employs an interchangeable panel design that allows for easy alterations. Meanwhile, Aston Martin has modified its rear wing too, trimming the central section of the upper flap’s trailing edge to reduce downforce and drag.
Alpine has introduced a large set of cooling gills on the bodywork of the A523 in Saudi Arabia to provide extra cooling. This is important given the heat generated during the race. The Red Bull RB19’s front brake assembly is also of interest due to its cooling rods that protrude from the caliper’s surface.
Ferrari‘s front brake assembly differs from that of Red Bull, with a substantial fairing around the caliper to reduce heat transfer. The rear brake of the Alfa Romeo C43 also employs a brake disc fairing to reduce heat transfer between various brake components.
Teams are also preparing for the race with new modifications. Williams appears to be readying the FW45 with its lower downforce package for the Saudi Arabian Grand Prix. Haas has chosen a rear wing option to boost its straight-line speed, with the upper flap having no Gurney on the trailing edge. The DRS pod is missing, suggesting that changes might still happen to the wing.
Finally, Alfa Romeo‘s DRS pod has been altered with a smaller conduit for the mechanism and conventional barrel-type flap pivots. The AMR23 brake assembly has also undergone heavy revisions compared to its 2022 version. The caliper has been moved to a lower position, and a brake disc fairing is now in use too.
