12. Mazda Eunos Cosmo
The Mazda Eunos Cosmo represents one of the brand’s crowning achievements in tech and luxury. Offered exclusively in Japan from 1990 to 1995, it boasted a remarkable triple-rotor rotary engine—the only production car ever to do so. Inside, drivers found cutting-edge features like touchscreen controls and advanced infotainment, rivaling the best from Lexus and Infiniti at the time. Despite its futuristic appeal, the Cosmo was never widely exported, making it a rare gem for those who appreciate Mazda’s boldest innovations.
