The Colt T120SS is available as either a bare chassis, a fixed-side pickup truck, or one where all three sides fold down, called "3-way wide deck". The engine used is either Mitsubishi's carburetted 4G17 or the bigger fuel injected 4G15. The smaller engine puts out at 6000 rpm. This engine had the same specs from its time of introduction in 1991 until it was replaced in 2005, except for one major difference: in 1996 it was redesigned and is no longer an interference engine. The larger unit, which meets Euro 2 emission standards, produces at 5750 rpm. Both engines feature three valves per cylinder. The bigger engine arrived in March 2005 with 1.5-litre Multi Point Injection, when the T120SS was also lightly facelifted, with a new grille featuring a triangular central portion. From 1997 to 2019, Mitsubishi Motors built 324,960 units of the T120SS.
