This is pretty obscure stuff but maybe something to ponder.
*When A.G.Eiffel was doing wind tunnel investigations of Maurice Farman struts,with struts of equal width,but with 'pointed' or 'blunt' forebodies,the blunt nosed struts had the lower drag.
The pointed strut had 50% aft-bodies.
The blunt struts had 60% aft-bodies.

*After Daimler Benz's success with the 200 mph 'pointed-nose' C 111-III,in 1978,they came out with a higher horsepower 250 mph 'blunt-nosed' C-111 IV.
----------------------------------------------------------------------------
*Porsche racing cars also saw an evolution in which they went to a flat nose.

* Also,in Hucho's 2nd Edition,Chapter 8,'Reducing aerodynamic drag,page 327,Fig.8.52,a 'Streamlined front-end' registered Cd 0.23 vs 0.22 for a nominally radiused blunt 'Baseline' nose.
A drop-nose 'Streamlined' nose did come in at Cd 0.21,reminiscent of VW's 'ideal' nose of the 1970s.
These noses constitute 5.84% of the overall drag.
The base drag at the rear constitutes 72% of the total drag.
