The second generation CD Cosmo appeared in 1975 and lasted until 1981. It was known as the Cosmo AP (Anti-Pollution) in Japan, and sold internationally as the Mazda RX-5, though in some export markets its piston-powered counterpart was called the Mazda 121 (a name later applied to Mazda's subcompact model).
Mazda America used the Mazda Cosmo name and offered it from 1976 through 1978, after which the Cosmo was replaced by the Mazda RX-7 as their rotary-powered sports coupe. The CD Cosmo/RX-5 series was positioned as a personal luxury car, offered as a notchback coupe, called the Landau, which included an "opera window" and padded vinyl roof covering, that appeared to be influenced by the 1970s era Lincoln Continental. It was also available as a fastback, but neither body style found many international buyers. It was however an enormous success in Japan where over 55,000 were sold in the first year alone. This new body style competed with the Toyota Crown, Nissan Cedric, Nissan Gloria, and the Mitsubishi Galant Lambda coupes newly introduced to Japan.
Due to its poor sales as an export the Series II version, built from 1979, was not exported and remained a Japanese domestic sale only. RX-4 exported to Europe saw very little competition in the rotary-engine equipped market, with the introduction of the short-lived Citroën GS Birotor, as well as any remaining NSU RO80 sedans.
The Cosmo was Mazda's largest rotary-powered coupe, based on the LA series Mazda Luce floor pan and mechanics, but slightly heavier due to body design and more luxurious appointments, including a five-link rear suspension and rear disc brakes. It was available with the 12A and 13B engines. This series Cosmo was joined by the short-lived Mazda Roadpacer, a large, heavy sedan powered only by a rotary engine.
A piston engine version, the Cosmo 1800, used a 1769 cc (80 x 88 mm) inline-four SOHC engine that produces 100 PS (73.5 kW) and 110 lb·ft (149 N·m). There was also the bigger Cosmo 2000 with 110 PS (81 kW).
The rotary engine had financial advantages to Japanese consumers in that the engine displacement remained below 1.5 liters, a significant determination when paying the Japanese annual road tax which kept the obligation affordable to most buyers, while having more power than the traditional inline engines.
