A series hybrid would have no gearing except for the fixed ratio from the electric motor to the drive shafts. The engine would be off except when it's needed to top off the battery, and at that time would run at peak efficiency.

I know there is efficiency loss with all the energy conversion steps, but a series hybrid reduces complexity and allows the engine to operate only at peak efficiency.
