The Chevrolet S-10 (and similar GMC S-15 and Sonoma) was a compact pickup truck from the Chevrolet 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 Ford Ranger has out sold the S-10 from 1987 on.

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

[edit] First generation

The first compact pickup truck from General Motors was the rebadged Isuzu KB 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. Added to this was the 4.3L V6 Vortec W code engine. This generation's last year, 1993.

The Vortec is essentially the standard Z code 262 cu inch engine. The difference is the W code used a balance shaft, roller cam shaft, different heads, and Central Port Injection. The 1992 and 1993 engine came in either a 195 or 205 HP rating. The High Perfomance version came with a larger diameter Y pipe, and was only installed in some of the Blazers and S-10 Jimmys.

[edit] 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 1991 GMC Syclone "super-truck". 806 Sonoma GT's were produced in 1992.

1993 Sonoma

Unknown quantity. Some 1993 Sonomas came with a factory equiped L35 W code engine. For 1993 no specialty labeling and or limited edition tags were known to be used with the w code engine.

[edit] Second generation

Image:ZR2a.jpg

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.

Much of the chassis components were the same as the first generation (the A-frames between the first and second generation were the same although they were originally sourced from GM's G-body vehicle lineup, along with the steering knuckle, leaf springs, and differential assembly. (the second generation came with an optional 8.5" rear differential) Generally, for the 2WD trucks, the 8.5" rearend was only used when it came with both a manual tranmission and the large 262" V6 engine, it was standard for 4WD trucks with either transmission. This was also the year that GM introduced the ZR2 Offroad Package.

The 4.3 L engines were refreshed for 1996 and a third (rear) door was added for extended-cab models. The exterior, interior, brakes, and 2.2 L engine were refreshed for 1998, and "Auto-Trac" all-wheel drive was optional starting in 1999 for the Blazers. Also the SS package was replaced by the "Xtreme" sports model package. In 2002 a CrewCab option was added and was available in 4WD and Automatic transmission only.

Base 2WD models came with 15x6.5 inch rims with directional vents, Xtremes and ZQ8 models came with 16x8" rims while 4WD models (including the ZR2) used 15x7" rims. The 14 inch rims used on the first generation were discontinued.
IZUSU HOMBRE
Second-generation S-series were also produced locally in Brazil; and are still in production even though S-series production ceased in 2004 in the U.S. Brazilian S-10s have a different front grille, lamps and bumper, and they also available with a 2.8 Diesel engine built by MWM.

The Isuzu Hombre was Isuzu's pickup introduced in 1996 as a rebadged Chevrolet S-10/GMC Sonoma. It replaced the Indiana-built Isuzu Pick Up. The most important difference between the two is in equipment — while the S-10/Sonoma boasted an extensive array of optional equipment, the Hombre was offered in a small model range with a modest selection of equipment packages. The Spacecab extended cab, V6 engine and four-wheel drive were added from 1997 to 1998. All three vehicles were produced at General Motors' Shreveport, Louisiana plant.

Hombres were equipped with the Chevrolet S-series 15 x 7 steel rims (with 8 directional vents) - the Hombre rims were painted black (the S10, Sonoma, and Blazer/Jimmy rims were painted silver) since a majority were equipped with hubcaps with the Isuzu logo. The only difference is the front sheetmetal - which was shared with the Brazilian-built Chevrolet S10 pickup.

Slow sales caused Isuzu to drop the Hombre after 2000. Isuzu would bail out of the pickup truck business until releasing the i-Series (which was a 2006-only vehicle). The Hombre is considered one of the rarest pickups in North America as of 2006.
