Its sleek, aerodynamic design and advanced technology, such as sequential twin turbochargers, positioned the FD RX-7 as a formidable competitor on both the street and the track. This model remains a highly sought-after classic, epitomizing Mazda’s commitment to performance and innovation.
Mazda 787B: Le Mans Legend
The Mazda 787B achieved legendary status by winning the 1991 24 Hours of Le Mans, making Mazda the first—and so far, only—Japanese manufacturer to win the prestigious race overall. Powered by a 2.6-liter four-rotor engine, the 787B delivered exceptional power and reliability, key factors in its victory.
This historic win demonstrated the potential of rotary engines in endurance racing, solidifying Mazda’s reputation in the motorsport community. The triumph of the 787B at Le Mans remains a testament to the ingenuity and passion driving Mazda’s engineering endeavors.
RX-8: A Unique Blend of Style and Innovation
Introduced in 2003, the RX-8 showcased Mazda’s ability to combine style with innovation. Featuring a naturally aspirated 1.3-liter Renesis rotary engine, the RX-8 offered a unique blend of performance and practicality, with its four-door coupe design and rear-hinged “freestyle” doors.
The RX-8 was praised for its balanced handling, impressive power output, and distinct design. Although production ended in 2012, the RX-8 remains a symbol of Mazda’s dedication to pushing the boundaries of automotive engineering while maintaining a focus on driver enjoyment.
Eunos Cosmo: Luxury Meets Rotary Innovation
The Eunos Cosmo, launched in 1990, was Mazda’s attempt to bring rotary technology into the luxury market. As the first production car to feature a three-rotor engine, the 20B-REW, the Eunos Cosmo delivered smooth power and a high level of refinement.
In addition to its performance capabilities, the Eunos Cosmo boasted advanced features such as an integrated GPS navigation system, a rarity at the time. Although it was produced primarily for the Japanese market, the Eunos Cosmo remains a fascinating chapter in Mazda’s rotary history, showcasing the versatility of rotary engines.
RX-VISION Concept: The Future of Rotary Dreams
Unveiled in 2015, the RX-VISION concept car offered a tantalizing glimpse into the future of rotary engines. With its stunning design and promise of a next-generation Skyactiv-R rotary engine, the RX-VISION captured the imagination of enthusiasts eager for Mazda’s return to rotary production.
