'''Wankel engine''' is a type of internal combustion [[engine]] with a rotary mechanism instead of pistons. It produces high torque but has low fuel efficiency, caused by difficulties sealing the rotor-cylinder interface. A small number of auto manufacturers have included Wankel engines in their vehicles, and while pioneered by Jensen and Audi, is now only available in one model of [[Mazda]], the RX-8
