Ah good thing the batteries are not the heavy part of the syatem otherwise this would be awkward.

This motor weighs 12.7 kilograms and has 1000hp. How much does a comparable motor weigh?

There is a 1000 hp tesla with 3 motors that all together weights about 450 killograms, this seems to support your idea until you look at how much the batteries weigh…
The batteries are 550 kilograms to start, and are generally considered to not be big enough. So yeah, great they solved the issue that no EV had (EVs always had lighter motors, and very heavy batteries).

~20% weight reduction for a total vehicle weight isn’t small change. Plus batteries will continue to improve as well. Do you just get off on being negative?

Yeah, I’m not sure how they concluded in their edit that 400kg is not a lot to shed.

Put the big battery pack (and maybe an ICE powered generator + fuel) on a trailer for cruising, then have a “ditch trailer and escape” button for that 20 mile sprint at the end of the trip.

Ah, yes. I too enjoy staging my road tripping vehicle like an interplanetary rocket.

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.
