Based on the principles and regulations of the Japanese keijidōsha class of vehicles, the MightyBoy is a coupé utility variation of the 2nd generation, 2-door fastback Suzuki Cervo. Released in 1983, it was equipped with an 534 cc SOHC 3 cylinder transverse-mounted engine (F5A), however unlike its cousin the Cervo, no turbo was available. Driving the front wheels through a 4-speed manual or optional 2-speed automatic gearbox, the F5A motor delivered 19 kW (25 hp) of power at the flywheel. Model designation for the Suzuki MightyBoy is "SS40T".
1st generation MightyBoys were fitted with 10" wheels, and sported a horizontally finned grille, identical to the Cervo. A feature unique to the MightyBoy were the seats, which although still similar to those featured in the Cervo CS/G, featured a customised embossed "MightyBoy" logo.
2nd generation Mightyboys received minor cosmetic upgrades, including a restyled front grille and mirrors. In addition the range was extended to two variants:
- PS-A - This 'base' model carried over the 10" wheels from the 1st generation MightyBoy and was available with a 4 speed manual transmission only.
- PS-L and PS-QL - This model was equipped with bucket seats, larger 12" wheels, chrome roof/tie-down rails, and a tachometer. In contrast to the base model, a choice of 2-speed automatic or 5-speed manual gearbox was offered.
The only export markets for the Suzuki MightyBoy was Australia and Cyprus between 1985-1988. Imported through Suzuki/Ateco, Australia received a hybrid of the Japanese PS-A and PSl/QL 2nd generation MightyBoy that included chrome roof rails, bucket seats and 12" wheels, however did not include such items as a tachometer or 5 speed manual gearbox.
