Mazda has launched the Mazda MX-30 e-Skyactiv R-EV, a plug-in hybrid model that uses a rotary engine as a generator, at the Brussels Motor Show1.

The MX-30 e-Skyactiv R-EV is a series plug-in hybrid offers owners new ways of using their car as a battery electric vehicle. It has an 85 km battery electric driving range as well as the ability to use a generator to enable long distance drives.

Mazda chose to use a rotary engine to power the generator system. Levering the unique way in which rotary engines can produce the required output with a small power unit, Mazda developed the new rotary engine to work as a generator and positioned it on the same axle as a high-output motor and a generator in the engine bay. Mazda then paired this compact electric power unit with a 17.8 kWh lithium-ion battery and a 50 L fuel tank to achieve the unique series plug-in hybrid system.
