Aerodynamics model

I am looking at the Aero tab in the Vehicle Physics software. The basics of Drag Force is clear for me, but I'm wondering if you can tell me the equation of the aerodynamics model and density of air. I'm just trying to guess the equations of the physics by placing the numbers.

The density of air is 1.293 kg/m3.
The equation is very simple F = 0.5*AirDensity*V*V*FrontalArea*DragCoeff.

Thank you for your quick reply. And any more I may come across in the future.

I have been playing with the aerodynamics model for two days.
It would be nice to have a dynamic simulation of air density.
Look, winter testing of F1 cars are faster.
Air density decreases with increasing altitude and depends on temperature or humidity.
A dynamic simulation of air density to each track and time of day can make it more interesting in terms of physics, simulation and races.

It looks very interesting for me. I will have to think about adding this kind of simulation to the server to synchronize all clients.
All clients must be in the same physics environment and have equal aerodynamics forces that are very significant at high velocity.

A compilation of the most known air density effects on F1 cars.

    - Power of the engine increases with increasing density of air. The same volume of air contains more oxygen.
    - Air resistance increases with increasing density of air.
    - Downforce increases with increasing density of air.
    - Cooling is better with increasing density of air. At the same time the engine is producing more power and heat.
    - Air and track temperatures. The grip increases with increasing of air temperature.

Is it going to be implemented in x motor racing?
