-> BMW made (no successful) experiments somewhen in the seventies with
-> octagonal ceramic pistons. I don't know why they used that shape and
-> how they machined the rings. Ceramic was not far enough in those
-> times and the pistons cracked when temperature changed rapidly.

??? I haven't come across that one yet, but I'd imagine the flat-sided
piston let them use spring loaded seals similar to those in a Wankel.
It would neatly sidestep the problems of doing an elliptical bore.
