9. Mazda Eunos Cosmo (JC, 1990-1996)
When Mazda created its upscale Eunos division in the early 1990s, the Cosmo represented the pinnacle of what a Japanese grand tourer could be. While early models featured V6 engines, the top-tier Cosmo was powered by the triple-rotor 20B Wankel unit, producing a substantial 300 horsepower. Aside from its potent rotary heart, the Cosmo introduced groundbreaking cabin technology: the world’s first in-dash touchscreen navigation system, a pioneering four-speed automatic with manual-mode switching, and HID headlamps—all in 1990.
Its aerodynamic profile and sumptuous leather-lined interior rivaled European GTs. Though sold almost exclusively in Japan, the Cosmo proved Mazda’s rotary franchise could underpin a sophisticated, luxurious high-performance coupe at the top of the segment.
