From 1985 to 1987, there was also the Sport GL, which included unique interior and exterior styling cues, an HSO (high specific output) version of the 2.3 L HSC engine (slightly more power), alloy wheels, tachometer, and a quicker gear ratio for the five-speed manual transaxle (3.73 final drive). It was badged simply as "GL", however the Sport GL was more easily recognizable because it lacked the GL's chrome front and rear bumpers. For 1987, the Topaz received a standard all-wheel drive system for the GS-AWD and LS-AWD trim levels. This all-wheel drive system (developed exclusively for the Tempo and Topaz) was available for model years 1987 to 1991.
