Making the motor lighter gives weight allowance for the onboard BESS. This could allow more batteries to be installed on the same car, increasing range and power/torque, so long as the volume of the car allows that same BESS increase.

It’s still good progress. I don’t understand your POV where we must focus on the BESS first and make that more efficient, both in terms of weight, volume, power, and energy, then move on to other things.

We can do that in parallel and see faster improvements.
