Your answer does not sound subjective?
I too,do not like the rotary engine, compared to other choices.
BUT, Mazda did have some success. I know that some people were satisfied with the platform.
I agree, it was not a long term performer like a diesel might be, but maybe this company worked out a few details?
The Coates system is as of yet, no better publicly?? Probably worse.
Mazda at least put them out in mass production.
