yeah it looks like a two rotor version of the single rotor. its so simple to do, i'm not surprised that they did it, i am surprised we're seeing it.
anyways it was at a conference for carbon neutral engines, so of course Rotary.
"We will continue to offer customers exciting cars by honing internal combustion engines for the electrification era and expanding the multi-pathway possibilities for achieving carbon neutrality. Given the rotary engine's compatibility with electrification and carbon-neutral fuels, Mazda will continue to develop the technology through co-creation and competition to ensure it can contribute broadly to society." （Masahiro Moro, Representative Director, President and CEO, Mazda Motor Corporation）
they also showed a new 8C prototype with Toyota's Hybrid Drive which allows for the engine to power the wheels together with the E motor, different than the MX-30 system
The reason for the extremely low height is the dry sump lubrication system. Instead of providing an oil reservoir at the bottom of the engine (the black part of the 1 ROTOR, which can also be seen in the e-SKYACTIV R-EV), the low mounting position is achieved by adopting a system that forcibly recovers oil using a pump. This is the same system used in racing cars and commercially available super sports cars.
The components are arranged in the following order from the front: 8C, 8C, generator motor. On the left side, you can see the water pump, oil pump, and oil tank.
The exhaust port layout doesn't look too balanced flow-wise front to back 🤔😬
