Mazda rotary engines have a reputation for being relatively small and powerful at the expense of poor fuel efficiency. The engines became popular with kit car builders, hot rodders and in light aircraft because of their light weight, compact size, tuning potential and inherently high power-to-weight ratio—as is true for all Wankel-type engines.
Mazda claimed to have solved the apex seal problem, operating test engines at high speed for 300 hours without failure. [11] After years of development, Mazda's first rotary engine car was the 1967 Cosmo 110S. The company followed with several Wankel ("rotary" in the company's terminology) vehicles, including a bus and a pickup truck. Customers ...
The Aero Design DG-1 (registered N10E) is an American racing aircraft designed by David Garber in an attempt to break the world airspeed record for a piston-engined aircraft. It is a single-seat aircraft with two Mazda RX-3 engines installed, one driving a tractor propeller, the other driving a pusher. The fuselage is bullet-shaped and highly ...
It is also a two-stage rotary engine, with the smaller combustion rotor on top of the bigger compression rotor. The rotors are connected with a gear ratio of 1 : 1 and rotate in the same direction. Unlike the R5 prototype, the 2-R6 uses the exhaust gas energy with its compression rotor instead of an external exhaust gas turbine.

Max Bentele (January 15, 1909 – May 19, 2006) was a German-born pioneer in the field of jet aircraft turbines and mechanical engineering.His contributions to the development of the Wankel engine earned him the title, "Father of the Wankel Engine in the United States".
The Mazda RX-Vision Concept, powered by a Skyactiv-R rotary engine, was unveiled in 2015 Tokyo Motor Show. [57] In 2023, Mazda unveiled the first production version of this generation of rotary engines. Used in the Mazda MX-30 R-EV, the engine provides 56 kW (75 hp) at 4500rpm and has a displacement of 830 cc in a single-rotor design. [58]
