El Mazda RX-7 FB, producido entre 1978 y 1985, es la primera generación del icónico deportivo de motor rotativo de Mazda. Cuenta con un diseño ligero y tracción trasera, y está impulsado por el motor rotativo de 1.1L o 1.3L de Mazda, conocido como 12A y posteriormente 13B. Estos motores ofrecen un rendimiento suave y de altas revoluciones, con potencias que varían entre 100 y 135 hp, según el modelo y el mercado.
El diseño del FB incluye una carrocería aerodinámica en forma de cuña, faros escamoteables y un habitáculo orientado al conductor. Su construcción ligera y distribución de peso casi perfecta lo hacen ágil y sensible en carretera, ganándose la reputación de ser un coche para puristas. El RX-7 FB es reconocido por haber introducido el motor rotativo a un público más amplio y por sentar las bases del legado rotativo de Mazda.

NOTAS DEL AñO
1978: The RX-7 debuted as a lightweight, rear-wheel-drive sports car featuring a 1.1L 12A rotary engine producing around 100 hp. The FB RX-7 (known as the SA22C in early years) had a sleek, compact design with pop-up headlights, offering a driver-focused experience. It came with a 5-speed manual or optional 3-speed automatic transmission.
1980: Mazda introduced minor updates, including slight improvements to interior materials and options like air conditioning, power windows, and a sunroof. Performance remained largely the same.
1981: The RX-7 received a slight power bump to 105 hp with adjustments to the 12A engine. Mazda also improved handling by refining suspension tuning and increasing chassis stiffness.
1983: Mazda introduced a refreshed RX-7 with styling updates, including new bumpers, taillights, and a revised front fascia. The GSL trim was introduced, featuring four-wheel disc brakes, limited-slip differential, and upgraded interior features such as leather seats and a premium audio system.
1984: The RX-7 received another significant update with the 12A engine upgraded for better performance and the introduction of the 13B engine (1.3L rotary) in the GSL-SE model, producing 135 hp. The GSL-SE also had fuel injection, improved brakes, and a more refined suspension setup, making it the most powerful and advanced version of the FB RX-7.
1985: The final production year of the first-generation RX-7. Mazda made minor adjustments, with no major changes, as they prepared for the second-generation RX-7 (FC) in 1986.
