Mazda Cosmo

There have been several Mazda automobiles named Mazda Cosmo.

69-72 Cosmo Sport 110S

The first Mazda to wear the Cosmo name appeared in May 1967. Called the Cosmo Sport 110S (or Cosmo Sports), it was the first rotary engine sports car. It was powered by a 10A two-rotor engine with 982cc of displacement and produced about 128hp. Equipped with a 5-speed manual transmission, the Cosmo Sport was good for over 120 mph.

The Cosmo name quickly became Mazda's halo name in Japan, and it was applied to many later premium sports cars. It was even briefly applied to the 929 in 1981.

75-80 Cosmo RX-5

The second generation Cosmo appeared in 1975 and lasted until 1981. It was known as the Cosmo AP, and sold internationally as the Mazda RX-5 and in the US as the Mazda Cosmo. It was a large rotary coupe very similar to the Mazda RX-4, but slightly heavier, and with independent rear suspension. It was available with the 12A and 13B engines.

81-90 Cosmo

The 1981 Cosmo shared the Mazda 929 chassis with its twin, the Mazda Luce. The Cosmo name was available on a coupe hatchback body in addition to the 5-door hatchback and sedan bodies available with the Luce name. The Luce was replaced in 1987, but the Cosmo soldiered on until 1990.

90-95 Eunos Cosmo

The modern Cosmo was based on the 1985 MX-03 concept car and started production in 1990. It remains the most powerful rotary-powered vehicle in history, and is the only Mazda to use a triple-rotor engine. This engine, the 20B, had two liters of displacement, which is quite large for a rotary powerplant. It produced better than 300hp with twin turbochargers. The car was a 2+2 coupe and was loaded with power amenities. See this link
