While the rotary has some great attributes, it's biggest problem, one that cannot be fixed, is poor volumetric efficiency.
A crescent-shaped combustion chamber is simply not as efficient as a round cylinder. Added to that is the combustion forces pushing the rotor at an angle- not directly onto a piston dome.
I had a first generation RX-7, and liked it. But with gas prices climbing, the rotary is less attractive, and will most likely remain an oddball.
