Alpine A523 detail

The Alpine A523 with a bi-plane style beam wing arrangement, with the large bow tie-style lower element. Note the small winglet mounted atop the arched central pillar mount, and this angle gives a good visual of how the airflow from the swage line on the external face of the endplate will interact with the upwash created by the diffuser and beam wing.

Williams FW45 detail

Comparatively, Williams have just the single bow tie-style lower beam wing arrangement but are also using a swage line on the outer face of their endplate.

Haas VF-23 technical detail

Heat rejection for the VF-23 has also been moved up top as part of the update, with the cooling gills now housed in the engine covers shoulder section, rather than on the upper surface of the sidepod, in order that can be better used to improve flow to the rear of the car.

Aston Martin Racing AMR23 technical detail

Aston Martin has also updated its floor edge and edge wing design for this race, with the team employing an external variant, rather than the underfloor one used so far this season. It’s in a similar style to many other solutions seen up and down the grid, with the forwardmost section rolled up and additional vanes added to help guide the airflow.
