OK, I promise that this is not another "Why can't I get the rated range on my Model 3?" question. I'm just trying to figure out how the EPA rated range matches up with the EPA's MPGe and kWh/mile ratings

Looking at the EPA ratings on fueleconomy.gov for the Model 3 AWD, Performance and Standard Range+ I find these stats:

Model 3 Performance and AWD (same stats):

In order to get 310 miles of range out of a 75 kWh pack, you actually need to have a car with an efficiency rating of 24.2 kWH/100 mile (242 Wh/mile). And I believe that is where Tesla is getting its "310 mile range" spec.

I know that it is *possible* to get 242 wH/mile out of a Model 3 LR AWD or LR AWD/P but real world numbers tend to be a bit less efficient than that. But real world vs. theoretical discussions aside, how can the EPA rating for fuel efficiency on the Model 3 AWD be 29 kWh/100 miles and yet the rated range be 310 miles? The numbers don't seem to add up.

Is my math wrong?
