Series 1 (1978–1980) is commonly referred to as the „SA22C” from the first alphanumerics of the vehicle identification number. In Japan it was introduced in March 1978, replacing the Savanna RX-3, and joined Mazda’s only other remaining rotary engine powered products, called the Mazda Cosmo which was a two-door luxury coupe, and the Mazda Luce luxury sedan.
