>With respect to the aerodynamics, there are some aspects that could make a difference between two cars, even if both fulfill the regulations and achieve homologation. The rules dictate how the performance of the cars (compared with the targets) must be measured and calculated. For drag, the reference condition is representative of an end-of-straight scenario in terms of ride height (considered to be the lowest setting); however, for downforce the definition is more complex and is based on a weighted average over a wider range of ride heights, roll angles and yaw angles.
>Moreover, in each aerodynamic configuration (this includes any possible setting of the single adjustable aero device the cars are permitted to deploy – an adjustable rear wing, for example), the two target values calculated as above must remain within a given window. This is shown in Figure 1. Cx and Cz are respectively the drag and downforce coefficient of the car; they are multiplied by the frontal area to get to CxA (vertical axis) and CzA (horizontal axis) as shown in the diagram.
