I don't know.
Afaik compression rings (well, not rings of course but seals or whatever you call it) show lots of loss and they burn oil (not a good trait for a clean car)
I've never seen a fuel efficient rotary car. Also not on highway miles.
If you compare their latest efford (rx8) to say an equivalent BMW (for instance a z4 with 3L i6 from the same era; similar weight and power) the bmw is so much more fuel efficient. Both in norm mileage as in real user data (bmw Z4: 9,5L/100km RX8: 13,4L/100km. This is based on real world data of ~300-400cars of both brands and probably tens of thousands of fill ups (spritmonitor)
But if any brand can pull it off, it's for sure Mazda.
But I don't think that platform is going to make it.
