Due to the porting, much like a 2-stroke reciprocating engine, a Wankel has a quite narrow gap on its RPM range where it will operate more efficient. Sometimes I wonder if a power valve system similar to what used to be common on some 2-stroke motorcycle engines are likely to overcome such deficiency, or if Wankel would only make a comeback serving as range-extenders.
