I this works, it's a formal, true-length, side elevation technical drawing of the 'Shorty.'
If a like image of the Ioniq 5 becomes available, the two images can be combined to allow a parametric examination of the aerodynamic 'system.'
At a combined length of 325.2-inches ( 8260.08 mm ) it would be possible to trick the air into experiencing Walter Lay's Cd 0.12, 1933 basic body.
Perhaps not with 'Shorty', but with something more sophisticated of the same 'length.'
