Mazda is bringing back the rotary engine in the form of a range-extending generator used in its MX-30 electric vehicle. This new rotary-powered, electrified powertrain is called the e-Skyactiv R-EV and is the only one of its kind on the market. The rotary engine powers the generator system and is positioned on the same axle as the electric motor. It never actually powers the wheels, though, like it does in actual hybrid vehicles, where both the combustion engine and electric motor provide propulsion.

One of the reasons Mazda chose the rotary engine for the MX-30 range extender is its ability to achieve a specific output with a physically smaller power unit. The e-Skyactiv R-EV powertrain is designed to offer a practical and seemingly effective method to boost the range of EVs. It also features an exhaust gas recirculation (EGR) system for further efficiency gains at low rpms as well as reducing its emissions.

The electric motor in the e-Skyactiv R-EV powertrain is paired with a 17.8 kWh lithium-ion battery, like you would find in any EV. That’s almost exactly half the size of the 35.5 kWh battery pack found in the Mazda MX-30 EV without the range extender. According to Mazda, this new rotary engine is lighter and more efficient than its predecessor. With its small 0.83-liter displacement, this direct-injected engine runs a high compression ratio to achieve a peak output of 73 hp.
