@BPeter and I were discussing this about a month ago when the updated EPC made its appearance; and the consensus was that both the LR and Plaid use the same motors, just without the carbon-wrapped rotors, and the high-current inverters that can make, and sustain the power. There is even evidence to suggest that both models share the same battery, due to the increased back-to-back-ability of both cars.Do we know whether the MSLR also uses carbon sleeved motors? I was perusing the EPC site and noticed that the price for the front drive unit is identical on both the Plaid and LR ($4000). The part number is slightly different, but that doesn't necessarily mean the physical hardware is significantly different.
It is possible that the front motor could be carbon-wrapped, but then it would be borderline useless in the LR, because of the different gearing on both axles. There is a 7.558:1 ratio on the front, and a 9.034:1 ratio on the rear axle. Tesla does this to get maximum power out of the rear motor as soon as possible from a standing start, and maximum efficiency out the front motor.
As a result, the rear motor's rpm is always significantly higher than that of the front motor. This means that at high speeds, the rear motor's power begins to fade until it stops making any notable power altogether. This also occurred in the previous P100D, and Cheetah MS. This is a factor in why after 130 mph, all of those models would slow down significantly. They effectively were being driven only by their front motors, which made about 300hp.
This is why a carbon-wrapped motor in front only wouldn't make any sense, because at high speeds, the LR would effectively turn into a FWD 300hp EV with a flat-ish power curve.
