4 rotor, motor disponuje výkonem 930HP při 10000 ot/min. Ale pro výdrž byl snížen jen na 700HP. 3 svíčky na rotor.
The Mazda Wankel engines (a type of rotary combustion engine) comprise a family of car engines derived from experiments in the early 1960s by Felix Wankel, a German engineer. Over the years, displacement has been increased and turbocharging has been added.
Wankel engines can be classified by their geometric size in terms of radius (rotor center to tip distance, also the median stator radius) and depth (rotor thickness), and offset (crank throw, eccentricity, also 1/4 the difference between stator's major and minor axes). These metrics function similarly to the bore and stroke measurements of a piston engine. Displacement is 3√3radius·offset·depth, multiplied with the number of rotors (note that this only counts a single face of each rotor as the entire rotor's displacement). Nearly all Mazda production Wankel engines share a single rotor radius, 105 mm (4.1 in), with a 15 mm (0.6 in) crankshaft offset. The only engine to diverge from this formula was the rare 13A, which used a 120 mm (4.7 in) rotor radius and 17.5 mm (0.7 in) crankshaft offset.
Mazda rotary engines have a reputation for being relatively small and powerful with the expense of poor fuel efficiency. They started to become popular with kit car builders, hot rodders and in light aircraft because of their light weight, compact size, and tuning potential stemming from their inherently high power-to-weight ratio - as is true to all Wankel-type engine. Mazda put them into serial production, with NSU (Ro80) and Citroën (GS Birotor), in the common COMOTOR company, between 1967 and 1977.
Since the end of production of the Mazda RX-8, the engine is produced only for single seater racing, with the one-make Star Mazda Championship being contested with a Wankel engine.
