Since there is a 2WD and a 3WD option, how will that affect the drain on the battery, or will AI control which motors are working?

The drain on the battery should be almost exactly the same:

For example, to maintain 50mph, Aptera should put about 6kW total drain on the battery.

- With FWD that's about 3kW per motor, times 2 motors is 6kW total drain.

- With AWD that's about 2kW per motor, times 3 motors is 6kW total drain.
