Well, actually it does. Look carefully at an animation of a wankel in
operation and you'll find that the rotor moves both vertically and
horizontally over a considerable distance.

Wankels are not turbines.

I understand your point but it seems intuitive that there is probably
less energy lost to overcoming reciprocating mass (pistons).


I'd have to agree. Change in direction is always a mechanical energy
loss.


The Wankel rotor reciprocates and is more massive than most pistons so
this saving is imaginary.


A Wankel rotor does NOT change direction.
