Electric scooters have a hub motor.
What about building hub motors that replace the rear rims on a FWD car?
Physically doable could be 7.5KW replacing a 13" rim?
One on each side totals around 15hp.
Batterys and controller in the rear and it could installed in half a day with little attention to existing components, barring controls, power steer and braking. Regen braking easy too. Louvre screens on grill to keep engine warm?
Should reduce running costs....70mpg to 150mpg??
Maybe large hub motors are available?? Or, who has a machining company?
Interchangeable inserts for the variety of wheel nut configurations and offsets.
On scooters power is generally supplied via a fixed center axle. This would be different....
Or, the whole rear wheel assembly could be remade with an electric motor driving a reduction box/rear axle.
Heres something from China:
