Thats how the "hybrid" car va tech had on display at the state fair was setup. It was a ford escape with a biodiesel subaroo drive train up front and an electric motor in the rear on the axles. Then a setup to go between the engine, motor, but required a lot of driver input to make work.
The gen 1 insight really is setting the bar as its easy to break 100 mpg. Why take a 17 mpg car, mod it to get 4 times that when you could just buy a better vehicle to start with and save you time and money?
