The RAV4 and Highlander (plus Lexus equivalents) have an AWD model with a hybrid engine/motor in front. There is no drive axle from the front drive unit to the rear. Instead, they have a single housing in the rear that holds an electric motor, 2-stage reduction gear at a 6.8:1 total, and a small differential.

It has the same appearance as the Tesla Model-S front motor housing (on the AWD version), but the Tesla unit is twice as fat and uses an induction rotor, and is certainly more powerful...this is a "Interior Permanent Magnet Synchronous Motor" similar to the Prius motor, but smaller...

This might be ideal for converting a large ATV "4-wheeler". He states that the motor by itself is rated for only 67-HP/97 ft-lb, but the high reduction provides a peak of 600 ft-lbs (V8 engine territory!)...stator at 15:00...rotor at 21:00...fast forward to 20:40

The only inputs are three fat motor-phase cables, a temp sensor, and the rotor position resolver. Everything is in an oil-bath, inside an aluminum finned housing. You would have to have two CV-joint half-shafts made (Toyota inners, VW bug outers (or whatever the conversion car is), etc

edit: here is a project where a builder is converting a vehicle with this unit.

10,752 rpm max at 288V, so...roughly a kV of 37-ish?

At 72V that would be approx 2660-RPM's max. One of the links said it was rated for 40A (continuous), so 72V x 40A = 2800W / 2.8-kW
 
Previous/Older 4wd Lexus Hybrids , (350H, 450H , etc) also had a self contained Edrive package for the rear axle.
But being part of the Toyota Hybrid system ,they were complicated by using a high ( 800 volt ?) drive /inverter package which needed some careful and special system design.
Hopefully, these full “EV” units will be more conventional
 
I have plans to use the rear AWD subframe from a UX250h in my Gen 3 Prius just using a canbus controlled motor and not an OEM motor.
