I am trying to figure out how to give my gasoline engine the constant electric assist that I would like for it to have, beyond the energy neutral task of stopping and then using the saved energy to move the car at the same momentum that it had prior to stopping.

Hybrids are a stop-gap between ICE and pure electric, and may not be optimal, like mixing gas and ethanol. The proper use is as an averaging function.

An electric assist that functions a highway cruise speeds would be plasma actuators. It's a design problem nobody has cracked yet.

Hub motors are problematic. This shows up in a search for '4wd f-body' but I won't touch Facespook with someonelse's 10ft pole. If you have no reluctance, there might be something there:

If you can get a front axle in there, then the Toyota/Lexus drivetrain is an option. It weighs 98lb and has 68hp:

I thought more overlap was bad for fuel economy? Too much overlap and the car idles so choppy that I couldn't tolerate the daily drive!

That's the problem anti-reversion fixes. Those sleeves about 6" from the exhaust port are them.
