Mazda’s Rotary Engine turns 40

A milestone in the technology of car propulsion has just been passed with the 40th birthday of the modern car rotary engine.

Mazda took up the challenge of rotary powered vehicles with it’s first vehicle, the Cosmo Sport. Though the original Wankel engines were underpowered fuel guzzlers even by that era’s standards, Mazda considered the engine a solid concept and continued with research and development.

Mazda’s modern turbo rotaries� have a firm and successful place in the import culture in the guise of the RX-7 (and to some extent, RX-2, RX-4 and RX-4) with Series� 1 to� 8 being a common sight on Australian roads, boosted to incredible powers, as well as occupying strong positions in motorsport around the world.

Mazda’s non-turbo RENESIS engine collected� the International Engine of the Year award for it’s debut in the then brand new RX-8, perhaps finally being recognised as a world class engine in it’s own right.
