The S-Series were made of line-up that includes sedans with trim models such as SL, SL1 and SL2; the coupes with trim models such as SC, SC1 and SC2; and the wagons with trim models such as SW1 and SW2. Either the SOHC Inline-4 or the DOHC Inline-4 engines with 1.9 liters displacement each mostly powered these models. Throughout the year of Saturn's existence, there had been many changes made both in interior and exterior.

 

During the year between 1991 and 1992, new look for the S-Series includes an added upper engine mount for reduced noise and vibration, revised seat-inset fabric for the SL2 and SC, polished alloy wheels with painted "geartooth" pattern also for SL2 and SC among others. In the late 1992 to year 1993, driver's side air bag becomes available, rear bumper and front bumper with optional fog lights were updated and a softer tires and suspension tuning were available for the SL2. These are just among the innovations that the S-Series vehicles had undergone. For so many years, there have been constant changes in the Saturn S-Series looks and equipments before it was finally replaced by the ION.
