Hey @R1S2000. There's not a lot of info on the dual motor setup but InsideEVs mentioned this back in March:

The dual-motor setup biases more torque rearward and also features front-to-rear torque control, which will provide a high level of on-road and off-road performance, as well as towing capability.

Rivian's new motor, designed in-house, will propel the dual-motor powertrains.

We have had plenty of vehicles doing all wheel drive with a single motor, so you could look at any number of solutions that are out there and guess what Rivian will do. As of now we know nothing at all.

Tesla does AWD with a single motor per axle -- which is what Rivian will be doing with the dual motor setup.

If you're referring to a single (total) motor driving all four wheels, that is also possible... That's how ICE vehicles have done AWD for a century.
Yes that makes sense, but will it lock and power split 50/50 to each wheel is the question.
And yes I understand it’s possible on a ICE vehicle, and if they wanted on an EV too however that would involve a driveshaft which isn’t really ideal for an EV chassis.

Which EV does AWD with a single motor?
I didn't say EV, just vehicles. My last 4 Audis have all had Quattro with a single motor, they figure it out. We get used to the EV 2 motors for 4 wheel drive but I am not sure that is how you have to do it, could be done with all sorts of solutions.

Yes but highly doubt anyone will do a single motor AWD EV when it’s easier to do dual motor. The weight and packaging disadvantages of the powertrain, drivetrain losses, etc will prevent that.
