The MX-30 R-EV uses a rotary engine that runs constantly to charge the battery, extending the range. Mazda presents this as having both the advantages of an electric drivetrain and the extended range of a gasoline powerplant.
As of now, the rotary engine's displacement in the MX-30 R-EV is unknown. It remains to be seen if Mazda would enlarge the electric motor's output ro cover for the weight of an additional engine.
The existing Mazda MX-30 EV has a 35.5 kilowatt-hour battery that offers an EPA-estimated range of 100 miles (161 kilometers). The MX 30 uses only one electric motor, which makes 144 horsepower (107 kilowatts) and 200 pound-feet (271 Newton-meters). Acceleration to 60 miles per hour (96 kilometers per hour) requires 9.6 seconds.
The Wankel engine has a long and prosperous history with Mazda. This type of Rotary engine was installed on the RX-3, RX-7, and RX-8. This is why the MX-30 R-EV's announcement is so exciting for Mazda fans.
