The content of the second paragraph that provides descriptive and clear information about the topic
History of the Mazda Rotary Engine
Mazda’s journey with the rotary engine began in the early 1960s, driven by a desire for a compact, lightweight, and powerful engine. German engineer Felix Wankel had developed the basic concept of the rotary engine in the 1950s, and Mazda acquired the rights to produce it in 1961.
The rotary engine’s unique design features a triangular rotor spinning within an oval-shaped combustion chamber. This design eliminates the need for reciprocating pistons, valves, and camshafts, resulting in a smoother, quieter, and more compact engine.
Notable Mazda Models with Rotary Engines
- Mazda Cosmo 110S(1967): The first production car to feature a rotary engine.
- Mazda RX-2(1970): A compact sports car known for its agile handling and potent rotary engine.
- Mazda RX-7(1978): A legendary sports car that showcased the performance potential of the rotary engine.
- Mazda RX-8(2003): The last Mazda production car to feature a rotary engine, known for its high-revving nature and distinctive exhaust note.
