How to distinguish between Mazda FC and FD?
3 Answers
FC and FD have significant differences in horsepower alone, with the FC producing approximately 185~205ps, while the FD delivers around 280ps. In terms of generations, the FC represents the second generation of the rotary engine series, whereas the FD is the third generation, which explains the difference in horsepower output between the two models.
The Mazda FC and FD are both nicknames for the RX-7. The FC represents the second generation, produced from 1985 to 1992. It features a classic design with pop-up headlights, giving it a more angular and robust appearance, straighter side lines, and simple yet functional taillights. The FD is the third generation, introduced around 1993 and produced until 2002. It has fixed non-pop-up headlights, a sleek and rounded shape, resembling the evolution of a sports car, with an overall lower profile for a sportier look. I often discuss these models at car meets, and the FD always strikes me as more modern and visually impactful, making it ideal for navigating city streets. Due to its older age, many used FC models may have issues with the headlight assemblies, so careful inspection of the vehicle's condition is necessary. In contrast, the FD's headlight design is timeless and less likely to be mistaken for another model.
The most obvious difference between the Mazda FC and FD lies in their engines. Having driven many rotary cars, I can say the FC uses a naturally aspirated or single-turbo 13B engine, delivering smooth horsepower but moderate power. The FD, however, upgrades to a twin-turbocharged 13B engine, offering quicker response and much more aggressive acceleration, with a stronger power burst at high speeds. In terms of maintenance, the FC's rotor is prone to carbon buildup and requires frequent cleaning, while the FD's turbo system, though efficient, has higher fuel consumption and more complicated part replacements. From my modification experience, the FD is better suited for performance enthusiasts, whereas the FC, with its simpler maintenance, is ideal for daily commuting fans.
