A look at the Chevy S-10

The GMC Sonoma was a compact pickup truck from General Motors. When first introduced in 1982, it was known as the S-15 - a sister model to the Chevrolet S-10 pickup. A high-performance version was the GMC Syclone. The Sonoma 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.

Isuzu was successful in marketing their compact pickup truck since 1972, and the 1973 Arab Oil Embargo forced GM to design a domestically-produced compact pickup truck as usual, parts from other GM chassis lines primarily from the GM G-body intermediates were incorporated.

The S-series was replaced by new models, the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series, in 2004.

1999 Chevrolet S-10 pickup


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. 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 135 hp (101 kW). The appearance was similar to the 1992 GMC Syclone "super-truck". 806 Sonoma GT's were produced in 1992.


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.
