Thanks to a generous offer from @efusco , we've got someone with an AWD 18" who's willing to gather data to let us compare the efficiency of an AWD and an RWD Model 3 in the exact same conditions. Obviously, for this we need someone with an RWD that's also running on 18" wheels who can get to the Springfield area (specifically, they're in Nixa). The test would be:
* Inflate tires to the same pressure (hopefully they have similar levels of wear!)
* Have the same amount of driver / cargo weight
* Head to a flat area with little traffic
* Drive the same road at the same time (but far enough apart so as not to draft) at a constant speed. Measure consumption (should only take a couple miles).
* Do the same in the opposite direction, to cancel out any minor wind/slopes
* Repeat for different speeds (such as 55, 65, 75 and 85mph).
This will answer once and for all whether the EPA efficiency differences are as big as they let on in the real world, or whether they're due to different testing configurations (such as different wheels or whatnot).
Any takers?
