I believe that Cd 0.25 is the 'beginning' of low drag.And since the 1970s,automakers have said that it's a cinch to achieve Cd 0.25 with silhouettes that consumers are familiar with.
So yes,we can build thousands of shapes that will achieve 0.25,Hucho mentioned this in the mid-80s.Sergio Pininfarina around 1980.
Hucho gave us six shapes in a single diagram which returned Cd 0.16-0.15.
These shapes require more careful contours and some wouldn't be fit as actual road cars.
Hucho says Buchheim et al's VW Flow body is the absolute limit as far as 'steepness' of contour.
