The frame on display in their showroom seems to have two motors in the back, except one of them acts as a generator (for regenerative braking). Maybe they changed the power routing to let it drive as well? Sounds like too small a change for such a fancy rollout.

This is just speculation but I doubt only one side handles the regenerative braking. If you think about it that wouldn't really make sense.

The dual motor would come into play making it an AWD car instead of just RWD, that seems more plausible.

There is one motor. The other large cylinder (that does look just like the motor) is the inverter: it turns the DC from the batteries into AC for the motor.
