Friction Drag:

Formula for Friction Drag (D)

Where:

C_Dis the drag coefficient - dimensionless and changes with air flow
A_D is the profile area - the area viewed from the front view of an oncoming car
q is the dynamic pressure - the pressure of the relative air speed to the vehicle

Related Concepts:

Yaw Angle - the angle between the orientation of the car and the direction the car is travelling in
How does this affect the drag coefficient? Is taking advantage of yaw angles feasible for MSXV (rear and front tires can both tilt to turn car orientation towards winds to minimize drag?)

Very Rough Body Sketch (Some Math)

*** Extremely extremely rough idea of an angle for aero body will probably be awhile to find the proper math ***
