There was a threat from me some time back where I was making some guesses about the minimum battery size for model 3 and I was laughed about.
But lets review again :)
Model S 70D have a range of 275miles or 254Wh/mile avg
Model 3 would have a range of 215 miles rated . If we assume 20% less consumption (which is a good guess as they aim at 0.2 drag coef alongside with smaller frontal area + 20% smaller car.
We can safely assume then that Model 3 avg would be in the 200Wh/mile range. That makes exactly 43KWh battery.
Knowing that the car will be ligther and more efficient probably I think its pretty save to guess 40 or 45 KW battery.
Red Sage , may be take your words back :)
