There have been four generations of Mazda automobiles which went by the name of Cosmo, although they are not all particularly related. All were GT cars, with the first proving a successful launch for the Mazda Wankel engine and acting as a halo vehicle for the new Mazda brand. Later Cosmos competed in the ultra-high luxury performance market in Japan with the final JC Cosmo (1990-1995) sold as the Eunos Cosmo - Eunos was a luxury sales channel similar to Toyota's Lexus brand.
