The Mazda Furai was a concept car manufactured by Mazda. The Furai, meaning "sound of the wind", was powered by a new generation 3-rotor Wankel engine that put out 450 brake horsepower (340 kW). The engine was developed and built by renowned rotary tuner Racing Beat, who also built the car's rotary-shaped muffler canister. Unlike many concept cars, the Furai was fully functional and was tested at various tracks. It has run at Laguna Seca and Buttonwillow.
