I'll take a crack at it.
Assumption: you start with a full charge of ~78.3kWh and drive at 75mph average until it stops.
Known relationship: energy required varies with the square of speed.
Calculation:

Energy Consumption from Tesla EPA testing of Highway Test Schedule:
Assumption: you start with a full charge of ~78.3kWh and drive at 75mph average until it stops.
Known relationship: energy required varies with the square of speed.
Calculation:
Speed 1 (average EPA highway test) | 48.300 | MPH |
Speed 2 (Hypothetical) | 75.000 | MPH |
Efficiency (average for HWY cycle from Tesla EPA filing) | 1764.600 | Wh/10.25mi |
Efficiency (average for HWY cycle from Tesla EPA filing) | 0.172 | kWh/mi |
Speed Ratio^2 | 2.411 | - |
Avg efficiency for Speed 2 | 0.415 | kWh/mi |
Total Energy Available | 78.269 | kWh |
Total Range at Speed 2 | 188.557 | mi |
