one 'man's' kit
In 1982,General Motors made a 'kit' for their Chevrolet Citation.
The standard Citation had Cd 0.45,Af 20.707 sq ft (est. @ 81%),and CdA 9.318 sq ft (0.864 sq meters).EPA 22 CITY/34 HWY.Popular Science drove the car at a constant 55 mph and saw 28.2 mpg.
----------------------------------------------------------------------------
The Citation was modified into the AERO X,with Cd 0.25,Af 19.463 (est),and CdA 4.865 sq ft (0.451 sq meters).
Mileage for the AERO X was EPA 25 CITY/49 HWY.If the AERO X performed like the Citation,it's actual on road mpg @ 55 mph might have been 40.64 mpg.
----------------------------------------------------------------------------
You could ponder what would have happened had they dropped an EV-1 body on,at Cd 0.187,or the streamlined EV-1 LSR boat-tailed version,with Cd 0.156.

If VW Beetles were still body-on-frame as in the 1970s,we might see a company like Fiberfab rise like Lazarus.
