The Mazda MX-30 e-Skyactiv R-EV plug-in hybrid provides the same benefits to customers as the fully electric Mazda MX-30 while expanding upon the EV experience. The R-17.8 EV's kilowatt-hour battery allows for a pure electric range of 53 miles, while the car's brand-new 83cc single-rotor gasoline engine doubles as a generator to allow for long-distance travel without worrying about running out of juice. Because the rotary unit of the MX-30 R-EV has no mechanical connection to the wheels, it just serves as a generator, so the electric motor is always driving.
