It's reported elsewhere, and I'm pretty sure it's here at EcoModder from many years ago.
They couldn't get the body below C d 0.161, whereas the half-body can do 0.08.
Adding wheels to the Morelli form jumped the Cd to 0.35. Only blending bulges around the wheels allowed Cd 0.201, as a 'production' car.
The half-body would begin at Cd 0.13 with skinny tires, and go up with increasing tire width.
Then wheel integration would whittle that back down to the tune of a 70% reduction of the wheel drag.
A 'wing' car might go to Cd 0.07 if you could get people inside it ( which you can't ).
Half-bodies, with active ground clearance and fairings would approach Cd 0.09.
