[citation needed] The rear-engine, rear-drive Suzuki Cervo (SS20), a kei-class sports coupé (or "personal car"), was replaced by a new front-engine, front-drive version based on the recently updated Alto and Fronte in June 1982.

Driving the front wheels through a four-speed manual or optional two-speed automatic gearbox, the F5A delivered 28 PS (21 kW) JIS at 6,000 rpm from the flywheel.

While the Cervo used rectangular headlights, the Mighty Boy, as befitting the cheapest car available in Japan, used cheaper round sealed beam units on most versions.

The range consisted of two variants, largely corresponding to the Cervo CS and CS-D/CS-QD:[1] In early 1985, the facelifted Mighty Boy received minor cosmetic upgrades, including a restyled front grille and mirrors.

Imported through Suzuki and Ateco, Australia received a hybrid of the Japanese PS-A and PS-QL second generation Mighty Boy that included chrome roof rails, bucket seats and 12" wheels.
