Model 3 battery size speculation

I know we wont know unless someone in tesla officially reports this or the drivers do a drive test and maybe have access to how the kwh used like in the model S or wk057 gets hands on a model 3 and do the necessary hack to get that out of the car or extrapolate from the official EPA numbers coming out later.

But my predictions are:
60KWh for 220 miles
85KWh for 310 miles

This is base on how much additional range you get and how efficient I expect the model 3 to be

60KWh/220 = 273Wh/mile which is pretty efficient
85KWh/310 = 274Wh/mile for a small increase in weight.

converting to mpge, it should be:
123.4 mpge for 220 miles version
123.0 mpge for 310 miles version

if we redo the numbers for 55KWh and 75KWh as some have been speculating, we will get:
55KWh/220 = 250Wh/mile which is too efficient I think unless they optimize everything (Speed, motor tech, drive tech, aero, acceleration, etc)
75KWh/310 = 242Wh/mile which is unlikely the longer range and heavier version to be more efficient than the lighter lower range version.

And the mpge:
134.8 mpge for 220 miles version
139.3 mpge for 310 miles version
Which I think is way too efficient.

A more accurate prediction is
55KWh and 80KWh
with 80KWh version being 258Wh/mile and 130.6.mpge
