If the new motor is scaled up slightly for the Cybertuck what kind of crazy performance can we expect from this more efficient motor variant???

I wouldn't expect anything more than what was already announced. While it's been almost two years since the Cybertruck was announced, I'm sure the range of the Cybertruck was with the new batteries in mind that they hadn't announced yet and the performance might have been with these new motors in mind.

The motor in the Plaid is the motor design they were planning for the Cybertruck.

Being you seem to be in the "know", any thoughts if it will be geared down a bit for more torque for the CT? Just thinking if the Model S Plaid is going to be capable of 200mph and the CT is going to be limited to 130mph and that torque is also a truck "thing", could we possibly see even better torque numbers than the Model S?

Wouldn’t expect Cybertruck motor design is repurposed MS Plaid but one engineered for torque-y stump-pulling, 14000# towing, super-low 4:1 rock crawling pedestrian 130 mph working envelope.

That would be customer convincing proof-positive Cybertruck is no parlor trick but an engineered real F-150 challenge to FORD.

These are induction motors to which the OEMs are reverting because of the high cost of the rare earths in the PMSRMs that they have been favoring up to this point. IM's are inherently less efficient than PMSRMs (copper and hysteresis loss in the rotor which you don't have in a PMSRM) but the new techniques with these copper rotor designs (such as the higher gap field strength) may recover some of that. Thus I don't think they will be any better than the PMSRMs, in fact I think they may be a little worse but that's just gut feel.

It will definitely be geared down more because one of the advantages of the carbon wrapping is that rotor speeds of up tp 20,000 rpm are possible.

Having a different reduction gear ratio is hardly a major redesign ^-^

It's probably the other way round, that is, this motor was developed for the CT and the Plaid S, as has been widely rumored, even among the staff at my local dealership, was a test bed for it. In any case the requirements for the motor for either are the same: max torque available at any speed up to the power limit and max power at any speed above that. This carbon wrapped motor has very close to this ideal characteristic and thus needs no re-engineering to go from the truck to the car or the car to the truck other than to change the gear ratio so that 20,000 rotor rpm corresponds to 130 mph in the truck (or whatever the CT top speed is) and 200 mph in the car.

It's an interesting exercise to compute the weight of the CT based on the 1000 HP available from the trio of S Plaid motors and the relative accelerations (1.36g and 0.94g). Assuming the S Plaid to weigh 4000 lbs the CT would weigh 5787. Not, I think, an unreasonable number.
