MMA 1986 Mighty Boy “BIGRIG” MMA #006 - 2020.

Suzuki Mighty Boy 1986 SS40T - PS-QL variant, the Australian Mighty Boy.

The Japanese Suzuki Mighty Boy (SS40T) was produced from February 1983 to January 1988. The Suzuki Mighty Boy still has a following in Japan and Australia. The 1986 Suzuki Mighty Boy Variant (SS40T - PS-QL) “BIGRIG” is the flagship of Microcar Models Australia.

The Suzuki Cervo SS40 was a rear-engine small sports coupé replaced in 1982 by a new, front-wheel-drive version based on the updated Alto/Fronte and in 1983 the Suzuki Mighty Boy was released based on this updated car.


The Mighty Boy retained the look of the Cervo with its wide B-pillars but was a microcar ute with a 600 mm long rear tray, low slung bucket seats distinguishing it from the cab forward style of other Japanese micro trucks on the market. Including sufficient space behind the seats for 2 suitcases or a good size dog.

In the era of the Kei Class of microcar, the Suzuki Mighty Boy was the only 550 cc coupe utility to be sold. In Australia and Japan, the Suzuki Mighty Boy was officially classified a commercial vehicle benefiting from lower taxes. A fleet of the cars was used by Domino’s Pizza in Australia for deliveries. The Suzuki Mighty Boy was exported to Australia and Cypress from 1985-1988. Australia received a hybrid of the Japanese PS-A and PS-QL second-generation Mighty Boy (see Variants). These included chrome roof rails, bucket seats and 12" wheels. However, it did not include such items as a tachometer or the five-speed manual gearbox. When introduced into Australia for AU$5,795 the Suzuki Mighty Boy was the cheapest car available at that time and 2,800 approximately were imported.


First-generation Suzuki Mighty Boys had 10" wheels and a horizontally finned grille, identical to the Cervo. While the Cervo used rectangular headlights, the Mighty Boy, as the most affordable car in Japan, fitted most versions with cheaper round sealed-beam lights.


There were 2 variants in the range which largely correspond to the Cervo CS and CS-D/CS-QD[1]:

  • PS-A – as the 'base' model retained the 10" wheels from the first Mighty Boys and was available with a four-speed manual transmission only.
  • PS-L and PS-QL - model were equipped with bucket seats, chrome roof tie-down rails, a coupé-style rear deck cover, and a tachometer. In contrast to the base model, it also offered the choice of a two-speed automatic (PS-QL).

The Suzuki Mighty Boy was face-lifted in 1985 receiving superficial upgrades, including a restyled front grille and mirrors. The more expensive PS-L variant benefitted from a five-speed manual gearbox, new seats, larger 12" wheels, and rectangular headlights and a new carburettor which increased power slightly to 31 PS (23 kW). Australian cars were the facelift type and claimed 22.7 kW (30.9 PS; 30.4 hp) and 43.1 Nm at 3,500 rpm.[2]


A new Cervo was presented in January 1988, and the SS40C discontinued and with it the end of the Mighty Boy.
