Japanese site Holiday Auto claims that Mazda will debut the so-called RX-9 at the 2019 Tokyo Motor Show. But before that happens, the Zoom-Zoom company will preview the production model with a concept at next year's Tokyo Motor Show. This  is very  important, to Mazda marking over 50  years since Felix Wankel came up with the rotary engine.  Now this car will come with over 400hp of rotary power.
