OK, so the Vanagon has a fixed shape and a sphere has a fixed shape.
Seems like what you are saying is the Cd is variable for a sphere but
fixed for the Vanagon?


How is that possible?  I think either shape profile is variable
depending on the Reynolds number.  I would bet the Vanagon profile would
go above 1 in the right conditions.

Yes...... a sphere can vary from the low 0.2 or so to around 2.0-ish
depending on Reynolds number (the ratio of inertial to viscous forces).
How weird is that!


The Van CD of 0.44 is what I remember also.
