It'll probably remain some kind of testbed, not for everyday use - 1st of all as a full fairing will cover the air outlets in the back and even wors my back light.
It could make for remarkable performance.
Dr. Kamm and Fachsenfeld's research indicated that, of a symmetrical wing section, the 'aft-body', past the maximum thickness, was responsible for a 892% drag reduction ( Cd 0.58-to- Cd 0.065 ).
And specific to 'wing sections', compared to say, a conventional saloon-type passenger car, bringing the rear to a 'point' maximizes drag reduction, regardless of the tail length. Truncating it as a 'chopped-off section' is the 'worst thing we can do.
