Mazda held the world premiere of a new sports car concept at the 2015 Tokyo Motor Show (TMS) last week. A total of 14 models were on display at the Mazda booth, including the rotary-engined RX-Vision Concept, the crossover concept Mazda KOerU making its first appearance in Japan, two racing-spec Mazda roadsters and the Cosmo Sport (110s outside Japan), first introduced in 1967.

The design of the RX-Vision Concept is modern, but maintains a sense of lineage and authenticity, appearing almost to condense Mazda’s entire history of sports car development into a single model. The 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 with exquisite, Kodo design-based proportions only Mazda could envision, and 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, 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. Over the years, the rotary engine has come to symbolize Mazda’s creativity and tireless endeavor in the face of difficult challenges.

While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine. 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 SkyActive Technology.


New-generation models in addition to the sports car concept, the Mazda KOerU is on display along with new-generation models featuring Skyactiv Technologies and “KOdO-soul of Motion” design. A motor sports exhibit feature racing-spec roadsters and the Cosmo Sport will complement a heritage display showing Mazda’s history of convention-defying engineering.

The vehicles on display include: Mazda’s new sports car concept Mazda KoerU; Mazda MX-5 cup racing-spec; Mazda roadster NR-A; Mazda MX-5 (special needs vehicle with hands-only controls); Cosmo Sport; Mazda Atenza (Mazda6) sedan; Mazda Atenza (Mazda6) Wagon; Mazda Axela (Mazda3) Hatchback; Mazda Demio (Mazda2); Mazda CX-5; Mazda CX-3; Mazda roadster (MX-5); Mazda Flair Wagon (with wheelchair ramp); SkyActiv-G 2.5 gasoline engine; SkyActiv-D 2.2 diesel engine; and SkyActiv-D 1.5 diesel engine.

Also, at the Smart Mobility City, which has been part of the TMS since 2011, showcasing the cutting-edge of Japanese technology in intelligent transport systems and smart communities based around the automobile, Mazda’s exhibit this year showcases the company’s safety philosophy and technologies. Displays explain the company’s HMI (Human Machine Interface), omnidirectional sensing concept and safety technologies developed in line with the Mazda Proactive safety philosophy, which aims to offer safety, peace of mind and driving pleasure by helping the driver recognize potential hazards, exercise good judgment and operate the vehicle in an appropriate fashion.
