my understanding was that you can run the gas engine in optimal speed to charge the electric engine which makes it more efficient.

- bluGill 2y agoYou can also add more gears in the transmission to make it more efficient as well. Gears are very efficient than conversion to/from electric (that is a series model, not even charging a battery.) The only way to make this work is if the engine is very undersized - the more load an engine is under the higher the efficiency, with gears alone though you would end up with an engine that takes unacceptably long to get up to speed, and slows down when going uphill, or into a headwind. If you are going ICE to battery you can have that undersized engine, and make up the extra losses by using the battery when needed, hence a hybrid car.
