Mazda is the brand most closely associated with rotary engines, but the technology actually originated in Germany.

The rotary engine was invented by Felix Wankel, who developed the design in the 1950s.

Mazda saw enormous potential in the engine and spent decades refining it.

Early Rotary Mazdas

Mazda released its first rotary car in 1967, the Cosmo Sport.

This vehicle proved that the rotary engine could be viable in production cars.

The RX-7 Era

The RX-7 debuted in 1978 and quickly became a global success.

Over three generations, Mazda sold over 800,000 RX-7s, making it the most successful rotary sports car ever produced.

The RX-8 and the Renesis Engine

In 2003 Mazda introduced the RX-8, featuring the Renesis rotary engine.

The Renesis improved emissions and fuel efficiency compared to previous rotary engines.

Despite ending production in 2012, the RX-8 continues to have a passionate fan base.
