Bob, 
 The engine in a Toyota Prius has overlap. My point is that it is NOT the sole determination of economy. This isn't the biggest factor for efficiency. I believe managing charge contamination is important, sure but not the only factor. I think the new direct injection systems will work very well with the rotary. The point is that getting the engine to pump the most air at a given RPM is "THE WAY."

And let me assure you, a P port will NOT get the same GPH. Theres a lot of fuel wasted with the P Port due to the overlap in timing.
