Mazda has announced that the rotary engine will return in 2020. The rotary engine has not been in a Mazda production vehicle since the 2012 RX-8. The rotary engine will be joined with an electric motor that will work as a generator when the battery runs low in an upcoming plug-in hybrid vehicle. Mazda claims that the vehicle with the featured setup may run on liquefied petroleum gas or on traditional gasoline. Mazda has set goals for the rotary engine hybrid vehicle to be able to provide electricity for home appliances when the power goes out.
A German engineer by the name of Felix Wankel submitted the first patient of the rotary motor in 1929. The first prototype of the rotary engine was introduced in the late 1950’s.
