Notes
La Mazda RX-7 FB, produite de 1978 à 1985, est la première génération de la sportive emblématique de Mazda équipée d’un moteur rotatif. Elle se distingue par une conception légère à propulsion arrière et est animée par le moteur rotatif 1.1L ou 1.3L de Mazda, connu sous les noms 12A puis 13B. Ces moteurs offrent des performances fluides et à haut régime, avec une puissance allant de 100 à 135 hp selon le modèle et le marché.
Le style de la FB comprend une silhouette élancée en forme de coin, des phares escamotables et un habitacle orienté vers le conducteur. Sa construction légère et sa répartition quasi parfaite du poids lui confèrent agilité et réactivité sur la route, lui valant la réputation d’être une voiture purement dédiée au plaisir de conduite. La RX-7 FB est reconnue pour avoir popularisé le moteur rotatif auprès d’un public plus large et pour avoir posé les bases de l’héritage rotatif de Mazda.

NOTES DE L'ANNéE
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.
