a rotary engine/electric hybrid? It would seem that this combo would give the best combination of features. The electric motor would provide the low end torque (which the rotary doesn't have), both being "rotary" designs would make the combo very smooth and having the electrics on board would improve the rotary engine's gas mileage. Also, the combined electric motor and the rotary engine would be a very compact assembly and lighter than a similar displacement piston engine hybrid. Am I missing something here or does this make sense?
