Planning on truncated end with about 8” height remaining. Total length off rear bumper needs to be just under 4 ft to haul needed cargo. It can’t taper more than 6” per side (looking from above left and right) also to clear cargo.

Car is 2012 Model S P85, cargo is a stack of display panels and EZ up tent.
The Daimler-Benz,Mercedes-Benz,1977 C-111,II record car was Cd 0.237,close to the Model S.
For 1978,they added 600mm of boat tail,and the drag dropped to Cd 0.195,for a new world record speed.
They had analyzed the car with up to 1,500mm of tail,which got them to Cd 0.178.
No tellin' how the S will respond to a boat tail,but we never know 'til we try.
What a great project!
