Saturn Owners Group

The S-Series was part of a family of compact cars from the Saturn automobile company. This was the first series of Saturn vehicles. The automobile platform, the Z-body, was developed entirely in-house at Saturn and shared very little with the rest of the General Motors model line. It implemented a spaceframe design, also seen on some Pontiacs, which meant that the side panels did not carry load and could use plastic pieces instead of metal. These polymer panels were dent-resistant—something that has remained a major selling point for Saturn through its later models. The S-series was sold from the fall of 1990 through the end of the 2002 model year, with redesigns in 1996/1997 and in 2000/2001.

The S-series debuted with SC (“sports coupe”) and SL (“sedan level”) models in 1990 as 1991 models. The SW (“sedan wagon”) debuted at the 1992 North American International Auto Show in Detroit.

Taiwan and Japan were the only two foreign countries that imported Saturns. From 1992 to 1996, the first- and second-generation sedans plus the first-generation coupes were sold in Taiwan. From 1996 to 2003, the second-generation versions were sold in right-hand drive in Japan.

A change partway through the 1999 model year gave the SC a small suicide door on the driver's side. This type of door had previously been used in extended cab pickup trucks, but was an innovation in coupe design.[1]

The S-series was replaced by the larger Saturn Ion in 2003, which was unable to match the S-series' success before the end of its own production at the end of 2007.

Coupes and sedans equipped with a manual transmission were among the most fuel-efficient cars available at the time, reaching 40 miles per US gallon (5.9 L/100 km; 48 mpg-imp) in EPA highway tests
