This nameplate was used in the U.S. market on Mitsubishi’s compact pickup line during the 1980s, appearing in manufacturer brochure materials for model years 1983 through 1988. It was positioned as a higher-content, more lifestyle-oriented version of the truck rather than a separate full-size model, and it is most often remembered as the upscale 2WD/4WD pickup trim sold before Mitsubishi’s later North American truck branding became more centered on Mighty Max. Contemporary coverage from the period shows the SPX being promoted as a more comfortable, better-equipped compact truck, while later data sources continue to associate the name with Mitsubishi pickup listings through 1988. The result is a short, distinct run with no evidence of a later revival under the same exact nameplate.
