only available in one trim level which was the SC. The 1990-1992 Saturn SC featured a DOHC 1.9-liter LL0 inline-four engine that was rated at . For the 1993 model year, the original regular SC coupe model was renamed as the SC2 and a new SC1 trim level was introduced. For the 1994 model year, the SC1 and the SC2 had both gotten revised power door locks and a recalibrated automatic transmission. The first generation SC2 had received a minor refresh in 1995 in which the lower front bumper and the vehicle's taillights were both updated. For the 1995 model year, both the SC1 and the SC2 had gotten a redesigned interior with a new redesigned dashboard with a front passenger's airbag. The first generation SC1 coupe featured a SOHC 1.9-liter LKO inline-four engine that was rated at . The SC1's engine was later upgraded to the L24 engine for the 1995 model year. The first generation Saturn SC1 coupes shared the same fixed headlight front fascia as the SL sedans and the SW station wagons, rather than the pop-up headlight design used on the SC2 and the original SC. The SC1 also lacked a rear trunk lid reflector and a rear stabilizer bar. SL3 For the 1994 model year, a highest-trim "SL3" model was planned. Saturn owner's manuals from this period made mention to the SL3- it would have featured an SC front end on an SL2 body, with all options as standard. An inline-six engine derived from the 1.9L was to be offered. Second generation Second generation SL and SW The second generation SL sedans and SW station wagons were made from 1996 to 1999. They had both featured a completely redesigned exterior. The interior was mostly the same as on the first generation vehicles, while mechanically they went largely untouched. The redesigned second generation S-series went on sale in 1995 for the 1996 model year. A few minor changes were made for the 1998 model year S-series vehicles. Due to multiple complaints about the noise coming from the vehicle's trip odometer that had been in all of the Saturn S-series since 1995, had replaced with a new type of trip odometer in an effort to correct the problem. For the 1998 model year, a new cluster with a digital trip odometer had been introduced. Rear disc-brakes were no longer available as an option on the S series
