In my search to find images of this vehicle I found an intersting website.

Still no signs of the Klemperer in question.

*For canopies,blisters,tanks,radomes,nacelles,etc.,you should consult 'AERODYNAMIC DRAG',by Sighard Hoerner.It is the book(s) which is most listed as a reference for such specific information,including Hucho.
*When 'combination',or,'composite' body structures are pieced together,the interaction of each component can create 'super-velocity' effects upon adjoining components and their aerodynamic characteristics are altered by the interactions.
The 'Template' would in no way be appropriate for designing such structures.

If you're interested in only limited 'low drag',then there are many options.
The NASA Dryden van would be one.This design would be patterned after DOT vehicle length and other restrictions.It does not reflect an 'ideal' solution,just an arbitrarily optimized one.

Seems to me like there are very limited opportunities to apply the template to existing and typically flat sided (and rectangular wheel layout) automobiles.

I don't think that I'll even bother considering these limitations, as it will never be perfect. Anyone who does a template overlay must be a misguided fool and totally ignorant to boot, right?:

* When the Template is 'split' in ground-reflection it is Cd 0.07
* When the 'ground-clearance' is cut away from the 'half-body' the Cd is 0.08.
* When skinny wheels are added to it the Cd jumps to 0.12.
* When wheel fairings are arranged around the wheels/tires,the Cd drops to 0.089.

Is this the official Part-C aero-Template Cross Section?

I've always assumed the Part-C aero-template would look like this (see image below) in front view, but I'm still looking for it.
