The Saab 900 Aero was introduced for the 1984 model year, or as it was known in the U.S. "Special Performance Group" (SPG). The Aero/SPG incorporated (depending on the market and model year) a body skirt; a sport-suspension (1987+) that included shorter, stiffer springs, stiffer shocks, and sway bars; leather seats; premium stereo; and air conditioning. Each of these features could, of course, be ordered independently from Saab's Accessories Catalog for fitment to standard models. Power output varied by model year and market, but 900S and 900 Turbo models produced after 1985 were fitted with a 16-valve engine, while the basic 900 kept the earlier 8-valve engine.

Some modern Aero-model Saab cars featured only a slight increase in performance, such as the Saab 9-3, while other models featured a dramatic increase in performance, such as the Saab 9-7X. The base 4.2i 9-7X produced 285 horsepower, while the Aero model produced 390 horsepower.^[2]
