The Sado 550 featured a 2-seater fibreglass body on a steel tube chassis equipped with a Daihatsu 547cc 4-stroke 2 cylinder engine powering the rear wheels. This gave the Sado 550 a top speed of 110 km/h (69 mph), which was faster than equivalent microcars in other European countries. Other features included a 4-speed gearbox, rigid axles with leaf springs front and rear and hydraulic drum brakes. Approximately 500 were built.
