I essentially selected the lowest drag architecture component from each of R.G.S. White's 1968 recipe categories for low drag, published in my CRC Handbook from the 1970s.
The summation of the categories is entered into an equation that he provides, and using all the 'best' components yields Cd 0.245.
Throw in Korff's NASCAR cooling inlet, rear skirts,and all the belly pan you can get away with, Cd 0.235 is not much of a reach.
At the time I was modifying, Sergio Pininfarina published that, all extant car shapes, already accepted by the public, could easily be modified to achieve Cd 0.25.
Hucho does address a signal-to-noise ratio, with respect to White's presentation, that's appropriate for the conversation.
Essentially, all the low drag cars of today look remarkably like White's 1968 creation.
PS, I did add 12-inches to the CRX.
