First generation SL The first generation SL was constructed for the 1991 to 1995 model years, with the first Saturn rolling off the assembly line in the
Spring Hill, Tennessee factory on July 30, 1990, the same day that then-CEO of GM,
Roger Bonham Smith, retired. It was maroon with a tan interior. From 1991 to 1992, the Saturn SL-series Sedan trim levels consisted of the
SL, the
SL1, and the
SL2. The base
SL model featured the
MP2 5-speed manual transmission only, and it had manual steering. On the exterior, the car featured unique hubcaps different from the SL1 and came equipped with only a driver's side exterior mirror (a passenger mirror was a popular dealer-installed option). On the inside, the SL featured a standard AM/FM radio with no cassette player and lower-grade cloth material on the seats. Some factory options such as power windows, power locks, or cruise control were not available on the
SL but air conditioning and an AM/FM/cassette radio were available on the option sheet. The
SL1 trim level added
power steering, a passenger mirror, different hubcaps for the 14-inch wheels, an AM/FM cassette player, and softer cloth material on the seats. It featured as standard equipment the same MP2 manual or the
MP6 4-speed
automatic transmission could be had as an option. The SL1 could be optioned with power windows, power locks, power mirror (passenger side only - driver's side retained manual control), cruise control, and air conditioning. Both were offered only with the
SOHC 1.9L I4 "LK0" engine that produced , which was rated at 27 mpg (8.7L/100 km/32 mpg) City, 34 mpg (6.9L/100 km; 41 mpg) Highway. The
SL2 trim level featured the
MP3 5-speed manual transmission, or the
MP7 4-speed automatic transmission, both exclusively with the
DOHC 1.9L I4 LL0 engine that was rated at , 24 mpg (9.8L/100 km; 29 mpg) City, 34 mpg (6.9L/100 km; 41 mpg) Highway. The SL2 also brought body-color bumpers, 15-inch steel wheels (alloys were optional), and higher spec cloth on the seats (including the seatbacks - on SL and SL1 the seatbacks were vinyl). SL2's could be optioned with power windows, locks, mirror (again, pass. side only), cruise control, air conditioning, sunroof, and leather seats. Anti-lock brakes were available as an option as well, which brought along rear disc brakes. For the 1995 model year, the seatbelts were changed from the power passive restraint type to the conventional 3-point type. The interior of the vehicle was redesigned with a new dashboard and the addition of a front passenger's airbag. The center console was updated as well, adding previously absent cup holders. Also for 1995, the SOHC (LK0) engine was given
MPFI to create the L24 engine. The S-Series had a fuel tank, which means that both cars got around on a single tank based on average of . Owners of the base model typically report real-world fuel mileage of about 38–41 mpg-US (6.2–5.7 L/100 km; 46–49 mpg-imp) on the highway with the manual transmission.
First generation SW For the 1993 model year, a station wagon variant of the SL was added to the model lineup. This was offered in SW1 and SW2 trim levels. The station wagon used the same doors as the sedan, but the bodywork behind the C-pillar and the roof differed.
First generation SC The first generation Saturn SC coupes were made from 1990 until 1996. The first generation Saturn SC coupes were originally 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
LK0 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 reportedly being considered. Saturn owner's manuals from this period made mention of the SL3 - it would have featured an SC front end on an SL2 body, with all options as standard.
