For AWD you could get hub motors on the front instead and use those as the only motor/generators (no need for an altermotor or anything connected to the engine)
Let me restate: there is no way to assist the gas motor throughout the entire drive unless you want to charge the battery yourself, because that energy has to come from somewhere. If you're simultaneously assisting from the engine AND dragging on it at the same time, with conversion losses, overall you'll be dragging on it. Anything else would be a perpetual motion machine.

I hope I am making myself clear...
In a nutshell, can I produce enough energy to offset what the two front steering wheel hub motors
only are consuming? This is why I suggested using another pair on the rear drive axle as
purely generators for the front hub motors that will be pulling the car while the gasoline engine is pushing the car with it's combined torque. IF this set-up were not producing enough power, I would have to resort to using an altermotor attached to my LT1 V8.
Am I still missing the point behind your comments?
I suppose I would have to settle with the electric hub motors kicking in for stop-and-go driving, my spirited "launches", and even for conditions on the highway when I don't have enough torque up a mild grade when cruising at 1500 RPM, but I don't see why I can't have the electric assist on all the time...
