RE: Car Aerodynamics

[Roland Broberg <broberg@cpg.mcw.edu>]

I think there is a misunderstanding here if I remember way back to my dynamics 
courses.  The Cd is measured in force/area.  It is not the drag, but the drag 
coefficient.  To do a true comparison between vehicles you'd have to multiply 
the Cd x the frontal area which is where the Q is lower since it has a smaller 
frontal area than the 5K.
