The Chevrolet S-10 (and similar GMC S-15 and Sonoma) was a compact pickup truck from the GMC marquee of General Motors. When first introduced in 1982, the GMC version was known as the S-15. A high-performance version was the GMC Syclone. The truck was also sold by Isuzu as the Hombre from 1996 through 2000. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. Together, these trucks are often referred to as the S-series.
The S-series was replaced by new models, the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series, in 2004.

First generation
The first compact pickup truck from General Motors was the rebadged Isuzu sold since 1972 as the Chevrolet LUV. The 1973 Arab Oil Embargo forced GM to consider designing a domestically-produced compact pickup truck, however. As usual, parts from other GM chassis lines (primarily from the GM G-body intermediates) were incorporated. The first S-series trucks were introduced in 1982. The Chevrolet and GMC models were identical apart from the grille. An extended cab and "Insta-Trac" four wheel drive were added the next year along with two new engines.
Track width was similar to the former GM H-body subcompacts (Vega/Monza).
The sport utility S-10 Blazer and S-15 Jimmy debuted; GM was the first to introduce compact sport utilities ahead of arch rivals Jeep and Ford. This trend occurred again where 4-door variants were introduced in March 1990.
New heavy-duty and off-road suspensions appeared in 1984 along with a hydraulic clutch, while the big news for 1985 was the discontinuing of the Cavalier's OHV I4 in favor of Pontiac's Iron Duke. The OHV-derived 2.2 L engine and Isuzu 1.9 L were both gone the next year, leaving just the Iron Duke and updated 2.8 L V6. A much-welcomed 4.3 L V6 was added for 1988, and anti-lock brakes came the next year.
The GMC S-15 became the GMC Sonoma in 1991, and the Sierra trim packages are dropped to avoid confusion with the new GMC Sierra full-size pickup. The GMC Syclone also appeared that year. The Sonoma GT bowed in 1992, and balance shafts were added to the 4.3 L V6 in this generation's last year, 1993.

Sonoma GT
A limited edition model was sold in 1992, the Sonoma GT. It used a 4.3 L L35 V6 which produced 195 hp (101 kW). The appearance was similar to the 1992 GMC Syclone "super-truck". 806 Sonoma GT's were produced in 1992.
Second generation
The second-generation trucks appeared in 1994. All of the special models (The Syclone, Typhoon, and Sonoma GT) were gone, but the changes to the truck brought it in line with arch-rival Ford Ranger. The Iron Duke and 2.8 L 60° V6 engines were dropped, leaving just the 4.3 L Vortec and a new 2.2 L engine, itself a derivative of the old Cavalier OHV. A high-output version of the 4.3 was offered on the "SS" model.
The 4.3 L engines were refreshed for 1996 and a third (rear) door was added for extended-cab models. The Isuzu Hombre version also appeared that year. The exterior and 2.2 L engine were refreshed for 1998, and "Auto-Trac" all-wheel drive was optional starting in 1999. An electric S-10 also appeared that year, balanced with an "Xtreme" sports model.
Base models came with 15 inch rims (with 16" used on the ZR2 off-road package and Xtremes).
Second-generation S-series were also produced locally in Brazil; it is still in production even though S-series production ceased in 2004 in the U.S.
