The 2002 Mazda Cosmo 21 Concept, unveiled at the Tokyo Auto Salon, offered a nostalgic tribute to Mazda's first rotary-powered sports car, the Cosmo, introduced in 1967. Based on the NB MX-5, this concept aimed to blend retro styling with modern performance by integrating Mazda's Renesis rotary engine, famously used in the RX-8, into the MX-5 chassis.
The exterior design of the Cosmo 21 was a departure from the standard MX-5, with virtually every panel reworked to evoke the aesthetic of its 1960s predecessor (the 1967 Mazda Cosmo Sport 110S). Notable features included circular headlights encased in bulbous housings, a distinctive front grille, and rocket booster-like taillights reminiscent of the original Cosmo. The convertible roof was replaced with a hardtop, and A-pillar wing mirrors were mounted on the front wheel arches.
Inside, the interior reflected the early 2000s era, with satin silver and black surfaces dominating the cabin. Quilted upholstery adorned various components, and zebra-patterned seats paid homage to the Cosmo's design cues.
Under the hood, the Cosmo 21 Concept borrowed the Renesis rotary engine from the RX-8, delivering an impressive 247 horsepower. While technical details remain scarce, the prospect of a rotary-powered MX-5 generated excitement among enthusiasts.
Unfortunately, the Mazda Cosmo 21 remained a concept, never making it to production. However, with Mazda's recent reintroduction of the Wankel rotary engine as a range-extender for the MX-30 EV, enthusiasts hold onto hope that a rotary MX-5 may become a reality in the future. Until then, the Cosmo 21 stands as a tantalizing glimpse of what could have been—a fusion of retro styling and modern performance in Mazda's iconic roadster.
