Mazda Motor Corporation unveiled the rotary-powered Mazda RX-VISION sports car concept at the Tokyo Motor Show. Although Mazda earlier put production of rotaries on hold, it continued R&D efforts in that area. The next rotary engine has been named SKYACTIV-R, expressing the company's determination to take on challenges with convention-defying aspirations and the latest technology, just as it did when developing SKAYCTIV TECHNOLOGY.

RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car powered by the next-generation SKYACTIV-R rotary engine.
Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967.
As the only automaker to mass-produce the rotary engine for a prolonged period, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car.
