The Chevrolet S-10 is a compact pickup truck that is produced by Chevrolet. It was the first domestically built compact pickup of the big three American automakers. When it was first introduced in 1982, the GMC version was known as the S-15 and later renamed the GMC Sonoma. A high-performance version was released in 1991 and given the name of GMC Syclone. The pickup was also sold by Isuzu as the Hombre from 1996 through 2000, but only in North America. There was also an SUV version, the Chevrolet S-10 Blazer/GMC S-15 Jimmy. An electric version was leased as a fleet vehicle in 1997 and 1998. Together, these pickups are often referred to as the S-series.
In North America, the S-series was replaced by the Chevrolet Colorado, GMC Canyon, and Isuzu i-Series in 2004.
The S-Series ended production in Brazil in 2012, being replaced by the Chevrolet Colorado, but still with the name S-10.

First Generation (1982-1993)
The first compact truck from the big three automakers was the rebadged Isuzu KB sold since 1972 as the Chevrolet LUV, and Ford quickly responded with the Mazda built Ford Courier also in 1972. The 1973 Arab oil embargo forced GM to consider designing a domestically produced compact pickup truck. As usual, parts from other GM chassis lines (primarily from the GM G-body intermediates) were incorporated. The first S-series pickups were introduced in 1981. The base engine (manufactured in Japan and imported) was a 1.9L Isuzu 4 cylinder (RPO LR1) shared with the LUV and Isuzu P'UP) with the GM 2.8L on the option list. The Chevrolet and GMC models were identical apart from the grille, tailgate and assorted insignia. An extended cab and "Insta-Trac" four-wheel drive were added the next year along with two new engines - a 2.0L (RPO LQ2) sourced from the J-platform automobiles along with an Isuzu 2.2L (RPO LQ7) diesel).
Track width was similar to the former GM H-body subcompacts (Vega/Monza).
The sport utility S-10 Blazer and S-15 Jimmy debuted in 1983; GM was the first to introduce the compact sport utility, followed by Ford and then Jeep in 1984. This occurred again where 4-door variants were introduced in March 1990 as 1991 models alongside the badge-engineered Oldsmobile Bravada.
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 2.0 L OHV I4 in favor of Pontiac's 2.5 L "Iron Duke" OHV I4. The OHV-derived 2.2 L diesel engine and 1.9 L SOHC gas engine, both from Isuzu, were 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 were 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 4.3 L V6 Vortec W code engine. This generation's last year was 1994.
The Vortec has a balance shaft, roller lifters, different heads, and Central Port Injection. The 1993 and 1994 engine came in either a 195 hp (145 kW) or 205 hp (153 kW) rating. The High Performance version came with a larger diameter Y pipe, and was only installed in some of the S-10 Blazers and S-15 Jimmys as well as the S-10 Pickups
The S-10 Baja is an optional appearance package that was put on any type 4wd S-10 (regular-cab w/ short-box, regular-cab w/ long box and extended-cab w/ short box) from 1989 to 1991. The trucks came in 3 colors: Midnight Black, Apple Red and Frost White. The Baja option included: a roll bar with off-road lights, a front tubular grille guard with fog lights, a tubular rear bumper, an under-body shield package (transfer case shield, front differential shield, fuel tank shield, oil pan/steering linkage shields), a suspension package, a Chevrolet windshield banner, Baja decals on the box sides and one inch wide body striping. Extra cost Baja options included: a cargo-net end-gate, aluminum outlaw wheels and a special box-mounted spare tire carrier w/ aluminum wheel. In 1991 the S10 Baja's came with special BAJA embroidered red and grey bucket seats and unique red door panel trim.

Second generation (1994-2004)
The second-generation trucks arrived in the 1994 model year. All of the special models (the Syclone, Typhoon, and Sonoma GT) were discontinued, but the changes to the pickup brought it in line with its major competitor the Ford Ranger. The Iron Duke 4-cylinder and 2.8 L 60° V6 engines were retired, the 4.3 L Vortec V6 was enhanced, and a new 2.2 L 4-cylinder engine (which had been introduced in 1990 on various FWD GM compact and mid-size platforms) became the engines of choice to power the second generation of S-10's. In compliance with the Clean Air Act, all 2nd Generation S-10s and Sonomas equipped with air-conditioning used CFC-free R134a refrigerant beginning in the 1994 model year. The all new 1994 S-10 didn't offer any airbag, presumably as a temporary measure to economize the introduction of the new body styles, as well as to gradually phase out steering wheel designs that didn't accommodate for airbags, though the vehicle itself was slated for airbag capability.
Many 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 but suspension and axles were greatly enhanced. Lower A-frames for the 2WD had 1/4 inch thicker steering stops - the second generation A-frames are commonly used as an upgrade for the first generation. Utility models (Blazer, Jimmy, Bravada) came with thicker front and rear sway bars.
Generally, for the 2WD trucks, the 8.5-inch rear end was only used when it came with both a manual transmission and the large 4.3 L (262 cu in) V6 engine; it was an option for 4WD trucks with either transmission. This was also the year that GM introduced the ZR2 Offroad Package.
For 1995, a driver's-side air bag was added as well as day time running lights. In 1996 the 4.3 L engine was refreshed, and a third (rear) door was added for extended cab models, along with the sportside bed option. In 1998, the exterior, interior, brakes, and 2.2 L I4 engine were refreshed, along with a "next-generation" supplemental restraint system that added a passenger-side air bag. "Auto-Trac" all-wheel drive also became an option starting in 1999 for the 4WD Blazers. The SS package was replaced by the "Xtreme" package. In 2001 a crew cab option was added and was available in 4WD and automatic transmission only. For the 2004 model year, the regular and extended cab models were discontinued; only the crew cab model was retained.
Base 2WD models came with 15x6.5-inch wheels with directional vents, Xtreme and ZQ8 models came with 16x8-inch wheels while 4WD models (including the ZR2) used 15x7-inch wheels. The 14-inch (360 mm) wheels used on the first generation were discontinued.
SS
The Chevrolet S-10 SS was a high-performance version of the S-10, introduced in 1994. Fewer than 3000 SS's were produced yearly on average. When introduced, the SS was sold in only three colors: Onyx Black, Summit White, and Apple Red. The SS was discontinued in 1998. In 1999, it was replaced by the S-10 Xtreme.
A 4.3-liter V6 (which was optional on regular S-10s) was the standard engine used in the SS version, producing between 180 and 200 hp (149 kW). The SS included lowered suspension (1996-98), cosmetic changes such as a different grille, body-colored bumpers, 16-inch wheels (1996-98, similar in design to the 1991/92 Camaro Z28 with bowtie center caps), and other sporty touches. All SS versions were regular cabs, Xtremes were available with the "third door" extended cab. A step-side version was available from 1996 to 1998 and thru 2003 on the Xtreme.
ZR2
The ZR2 package was an off-road package available for the second generation Chevy S-10. The ZR2 package included a 4-inch (100 mm) wider track width, a boxed ladder-type frame with modified suspension mounting points, larger wheel and axle bearings, 31-inch all-terrain tires, a suspension lift (approximately 3 inches more ground clearance vs. a regular 4wd S-10), upgraded Bilstein suspension, fender flares, alloy wheels, and an 8.5-inch Chevy 10-bolt rear differential with 3.73:1 gears and Eaton MLocker (Coded as G80)
Isuzu Hombre
In 1996, Isuzu replaced its Pick Up with a version of the Louisiana-built Chevrolet S-10, the Isuzu Hombre, based on the Brazilian market S-10 (the front grille and fenders are based on the Brazilian S-10 along with the truck bed sheet metal). The Hombre differs from its GM siblings mostly in the front sheetmetal, with different lights, grille, front bumper and front fenders, which are more flared out. The rear quarter panels are also different, as they have a slight flare over the wheel well to match the front fenders. - which was shared with the Brazilian-built Chevrolet S10 pickup. The Hombre had a much smaller range of equipment options. The Spacecab extended cab, V6 and four-wheel drive was added from 1997 to 1998.
Two trim levels were offered: the base S and the uplevel XS. The XS had features like a cassette tape deck, higher-grade interior fabric, a tachometer, a sliding rear window, and a split 60/40 seatback. Hombres were equipped with the Chevrolet S-series 15 x 7 steel wheels (with 8 directional vents) - the Hombre wheels were painted black (the S10, Sonoma, and Blazer/Jimmy wheels were painted silver) since a majority were equipped with wheel covers with the Isuzu logo. Hombres were also available with the S-10's aluminum wheels with Isuzu center caps.
Slow sales resulted in production ending in 2000. It would be another six years before Isuzu re-entered the pick-up market with another rebadged Chevrolet, the i-Series.

Third generation (2012-present)
Although the North American version of the S-series was discontinued in 2004, the second generation S-10 was still being built in Brazil and Canada until 2012, when it was replaced by a Brazilian or Canadian built version of the Chevrolet Colorado called the S-10.
In Brazil, until 2014, the third generation S-10 offered a 2.4 L 147 cv Flexpower flex-fuel engine or a 2.8 L 180 cv Duramax diesel engine. For 2015 models, diesel engine received some upgrades and remapping and now offers 200 cv. The flex-fuel (gasoline/ethanol) engine had an upgrade for some versions (LT and LTZ) and offered 206 cv with a 2.5 L LCV Ecotec with direct fuel injection. Versions with a "SIDI" badge on the tailgate. Also, for the first time, Chevrolet offered in Brazil the flex-fuel S-10 with 4WD traction.
By 2016, for the 2017 model, the model received a face-lift and also the flex-fuel 2.4 L engine was dropped. The other engines options were unchanged. For 2018, the flex-fuel S-10 now offers automatic gearbox, as market trend on these vehicles.
