The Chevrolet S-10 Blazer (4WD model T-10) and its badge engineered GMC S-15 Jimmy (4WD model T-15) counterpart are compact/mid-size SUVs manufactured and marketed by Chevrolet and GMC from the 1983 through 2005 model years across two generations.
The S-10 Blazer and S-15 Jimmy were based on the Chevrolet S-10 and GMC S-15 pickup trucks and were manufactured in Pontiac, Michigan; Linden, New Jersey; Moraine, Ohio; Shreveport, Louisiana; Ottawa, Ontario, Canada; Oshawa, Ontario, Canada; and São Paulo, Brazil.
In the United States, retail sales of four-door Blazer models ended in 2001 (fleet sales continued into 2005); production of two-door models and four-door models for fleet sales continued until 2005. In the Canadian market, four-door models of the Blazer and Jimmy were sold until the 2004 model year and until the 2005 model year for the two-door models of both.
The Brazilian variant, based on the second-generation S-series, continues in production in Brazil with their own sheetmetal stampings as well as in Canada with the Brazilian, Indonesian and Russian sheetmetal stampings). In North America, the Moraine, Ohio plant produced only 4-door vehicles, with both 2- and 4-door models being produced at Linden, which was the main assembly plant after the switch (some time after 1995) from Pontiac, Michigan, which became a full-size truck plant.

Chevrolet introduced the S-10 Blazer in 1982 along with its rebadged variant, the GMC S-15 Jimmy, and S-10 pickup truck, the latter replacing the Isuzu-based Chevrolet LUV. The Blazer and Jimmy appeared as 1983 models.
The S-series Blazer and Jimmy did not feature removable hardtops like their full-size counterparts and were only offered in a two-door bodystyle.
Base power was provided by GM's 2.0 L OHV four-cylinder engine, producing 83 hp (62 kW). A 2.8 L, 110 hp (82 kW) V6 was offered as an option (coincidentally this engine was also used in Jeep's competing Cherokee until 1987).
Due to emissions laws, a 1.9 L I4 gasoline engine built by Isuzu was offered as the base model engine in California in place of the 2.0 L engine, while an Isuzu 2.2 L diesel engine (also used in the S-series pickups) producing 58 hp (43 kW) was offered as an option.
The 1.9 and 2.0 L gasoline fours and the 2.2 L diesel were dropped after 1985, replaced by the larger 2.5 L Iron Duke engine. The V6 was refitted with a throttle-body fuel injection system for 1986 in order to improve performance and fuel economy.
In order for it to keep being competitive, the Blazer and Jimmy received a new 4.3 L (262 cu in) V6 option for 1988 (also used with the Astro/Safari vans, short wheelbase G-series vans, and light duty C/K-1500 trucks), based on the Chevrolet Small-Block V8 engine, producing a respectable 150 hp (110 kW). Power output was increased to 160 hp (120 kW) for 1989, while the four-cylinder engine was dropped. The 2.8 L V6 was discontinued after 1990, making the 4.3 L the sole available engine. A 5-speed manual transmission (Getrag 290/Hydramatic 290/5LM60, sourced from the GMT400) was added to the option list, replacing the Borg-Warner T-5.
In March 1990, 4-door versions of the S-10 Blazer and Jimmy were introduced as a 1991 model; the 4-door had a 6.5 in longer wheelbase (2-doors had a 100.5 in wheelbase - six inches (152 mm) longer than the Ford Bronco II) and a one-piece front grille with a painted black insert (1990 2-door S-10 Blazers and Jimmys had the 3-piece grille). This new grille also did away with the separate metal filler panel under the grille, since the grille is taller and took its place. Early production models between March and August 1990 were initially available as a four-wheel drive only; 2WD versions commenced production around Summer 1990. This came just months ahead of the introduction of the Ford Explorer, which replaced the Bronco II; six-and-a-half years after the segment-leading Cherokee debuted with four doors. Snowflake alloy wheels (similar to the ones used on the Chevrolet Astro/GMC Safari) were introduced, either painted charcoal gray or argent silver.
The upscale Oldsmobile Bravada appeared later in the year featuring an All-Wheel-Drive package called "Smart-Trak" (using a BorgWarner 4472 transfer case, shared with the AWD Astro/Safari).
1992 models were similar to 1991s - the only way to tell the difference is the rear back glass (the rear glass does not have any trim to which two black buttons serve as the back glass strut mounting points) and front grille (chrome shell with argent silver inserts). The interior was a carryover from 1991 with the exception of the center console and steering wheel (X-bar style similar to the one used in the GMT400 trucks). Also, the "S-15" name was dropped from the Jimmy. The S10 Blazer also introduced an upscale Tahoe and Sport trim packages, the Tahoe LT, which was rebadged as the LT in 1995 whilst the Tahoe package was renamed as the LS. The Tahoe LT had its own exterior décor with faded lower body lines on the lower rockers along with Tahoe LT badges - this also included an overhead console and keyless remote door locks). Sport package had bigger sway bars, slightly modified suspension and 30x9.5 or optional 31x10.5 tires. Body trim included also black plastic fender flares, front fog lights and spare tire carrier on the tailgate. 1992 was the first model year where the S10 Blazer and Jimmy offered an NP233 electronic transfer case for as a drive train option. This deleted the Manual gear range selector with a 3 position switch located to the left of the gauge cluster in the same location that the rear defrost button would be located on non-electronic transfer-case and 2WD model Blazers and Jimmies (when optioned with the electronic transfer case the defrost button assembly is positioned below the headlight switch). The electronic transfer-case added luxury however there was no neutral position with the electronic transfer case, so the owner's manual stated that the drive shaft had to be removed when the vehicle was being towed. The fuel lines, which were routed on the driver side frame rail to the TBI fuel injectors, were redesigned where the fuel inlets entered the rear of the engine (same as the GMT400). This was phased in because of the L35 option which used a similar fuel line setup. The serpentine accessory drive for the 4.3L motor was modified where the air pump was eliminated and further lightened.
From at least 1991 onward, all S10 Blazers and Jimmies came with four-wheel anti-lock brakes as standard equipment. The first two years of the ABS system had axleshafts with pressed-on ABS toner rings, which were eliminated during the latter half of the 1993 model year (rear ABS control was now done via the vehicle speed sensor). A 5-speed manual transmission remained standard through 1994, but only with the TBI engine. Only the two 4.3 L (262 cu in) engines were offered as options - the base TBI and the CPI (introduced in 1992 for the S-series and Chevrolet Astro minivans; the latter had the "Vortec" logo on the intake plenum).
1993 had a few changes - the center console was raised (with a dual cup holder), and the 4L60E transmission replaced the 700r4. The grille (alongside the S-10 pickup) was revised (which was a chrome-plated version of the base work truck grille found on base S-10 pickups), along with the addition of optional 5-spoke alloy rims (for the 2WD model - basically a copy of the 3rd generation Camaro Z28 15" alloy rim).
Although the second generation S-series pickup debuted in 1994, the S-10 Blazer and Jimmy continued unchanged for that year, with the only significant changes being a third brake light and the discontinuation of the rear spoiler. 1994 was a transition year for many automakers when it came to switching from R-12 Freon to CFC-free R134a refrigerant. The redesigned 1994 S-10 and Sonoma pickups used R134a refrigerant. Despite being nearly identical to the 1993 models, the entire 1994 model year full-size pickup and SUV lineup (C/K, Sierra, Suburban, Yukon, etc.), also used R134a. The 1994 S-10 Blazer and Jimmy seem to have used R-12 until the end of their production run and subsequent replacement with redesigned 1995 models that looked like new-for-1994 pickups.

The all-new Blazer was introduced in 1994 as a 1995 model year. This time, it lost the S-10 prefix for simpler identification, as the full-size K5 Blazer was discontinued. (the GMT400-based Blazer was rebadged as the Tahoe; the Tahoe package which was the base trim for past S10s was redesignated as the LS.) The Blazer was Playboy magazine's Truck of the Year for 1995 and was also the unanimous winner of the Motor Trend 1995 Truck of the Year. The '95 Blazer was also awarded North American Truck of the Year at the North American International Auto Show in Detroit. Exterior and interior size were increased, bumping it up to a mid-sized SUV.A drivers airbag came, but a passenger airbag wasn't immediately introduced. This Blazer appealed to more customers because of the less rugged appearance and rounded styling, and many storage spaces—a key feature for families. It was available with the 4.3 L V6 engine only, and most models featured four-wheel drive via an electronic transfer case; 1997 was the last year a manual transfer case for 4 wheel drive (floor shifter for 4 wheel drive) was offered. In 1998, the interior and exterior received some cosmetic changes. The makeover offered a new dashboard with larger buttons and more ergonomically correct driving controls, as well as larger door handles, and headrests for the rear bench. A passenger airbag is now standard. A front grille similar to the Chevrolet C/K pickup line's stacked-headlight system replaced the older single-headlight system, similar to the full-size GMT400 trucks. 4 wheel disc brakes became standard equipment, fitted with aluminum dual-piston calipers (the front disc brakes were redesigned with the dual-piston calipers and 11" diameter brake rotors (steering knuckles now have sealed hub assemblies) while the truck models retained the 1978-era single piston disc brakes originally sourced and shared from GM's G-body lineup). In 1999, new folding mirrors replaced the old folding mirrors. 2000 saw new front bumpers and the trim running along the sides and bumpers was removed. For the 2001 model year, the truck received a new center console.
In 1999, Chevrolet introduced a limited edition 'TrailBlazer' appearance package that was available as an upgrade to the LS and LT trims. The package featured gold-accented alloy rims and trim along with several interior/exterior modifications and upgrades and was marketed until the introduction of the GMT360 series for the 2002 model year. The Trailblazer's headlamps, which featured daytime running lamps, would be available on various Blazer models until production ended. Upon introduction of the 2002 Chevrolet TrailBlazer and the GMC Envoy, production continued after their successors came to the market, with the Jimmy being sold only in Canada and, in the 2005 model year, 4-door models sold to vehicle fleets. Another upscale model was the 1998 GMC Envoy . It used the same engines and had many of the same upgrades as the Bravada. The 1998 model Envoy featured an optional upgrade to High Intensity Discharge headlamps, and several other visual modifications. To celebrate the 30th anniversary of the Jimmy nameplate, the Jimmy Diamond Edition was launched. Not too different from the Envoy, it featured leather seats with a diamond pattern, special diamond logos, and an aluminum silver plate along lower sides of the SUV.
At the same time, a Blazer Xtreme (only on the 2-door model) was added to the lineup, based on the S10 Xtreme. This sub-model lasted until 2004.
The second-generation Blazer was officially sold in Taiwan, between 1995 and 1996.
The ZR2 Package
The ZR2 package was only offered on the 2 door Blazer as the 2 door had the shorter wheelbase. It had a wider ladder-type frame which made its track approx. 3.9 inches wider. It also lifted the Blazer about 3 inches which made it be able to clear 31x10.5 tires on 15 inch wheels. An enhanced front (7.25" ring gear) and rear (8.5" ring gear) axles w/ 3.73:1 rear-axle ratio. Larger wheel and axle bearings. A front anti-sway bar, skid plates, Bilstein shocks, and a beefier rear axle. This package cost a little over $1000 and was first introduced on the S10 pickup in 1994 and carried over to the Blazer in 1996.
IIHS gave a P for poor in the frontal offset crash test.

The Chevrolet Avalanche is a four-door, five or six passenger pickup truck sharing GM's long-wheelbase chassis used on the Chevrolet Suburban and Cadillac Escalade EXT. Breaking with a long-standing tradition, the Avalanche was unavailable as a GMC, but only as a Chevrolet. Production of the Avalanche started in September 2001 and ended April 2013; producing two generations in its lifespan.
The Chevrolet S-10 is a compact pickup truck that was produced by Chevrolet. It was the first domestically built compact pickup of the big three American automakers. When it was first introduced as a "quarter-ton pickup" in 1981 for the 1982 model year, 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.
The GMC Envoy is a mid-size SUV that was produced by General Motors from the 1998 to the 2009 model years. Adopting a nameplate used by GM Canada, the Envoy was the direct counterpart of the Chevrolet TrailBlazer SUV; two generations of the model line were sold.
The Chevrolet Silverado is a range of trucks manufactured by General Motors under the Chevrolet brand. Introduced for the 1999 model year, the Silverado is the successor to the long-running Chevrolet C/K model line. Taking its name from the top trim level from the Chevrolet C/K series, the Silverado is offered as a series of full-size pickup trucks, chassis cab trucks, and medium-duty trucks. The fourth generation of the model line was introduced for the 2019 model year.
C/K is a series of trucks that were manufactured by General Motors from the 1960 to 2002 model years. Marketed by both the Chevrolet and GMC divisions, the C/K series encompassed a wide range of vehicles. While most commonly associated with pickup trucks, the model line also included chassis-cab trucks and medium-duty trucks and served as the basis for GM full-size SUVs. Through its entire production, the model line competed directly against the Ford F-Series and the Dodge D series.
The LS based small-block engine is the primary V-8 used in General Motors' line of rear-wheel-drive cars and trucks. Introduced in January 1995, it is a "clean sheet" design with only rod bearings, lifters, and bore spacing in common with the longstanding Chevrolet small-block V-8 that preceded it as the basis for GM small-block V-8s. The basic LS variations use cast iron blocks, while performance editions are all aluminum with cast iron cylinder liners. The engine block and cylinder heads are cast at Saginaw Metal Casting Operations in Saginaw, Michigan.
The Chevrolet "big block" engine is a term for a series of large displacement 90° overhead valve V8s that were developed and produced by the Chevrolet Division of General Motors from the 1950s until 2009.
The Oldsmobile Bravada is a front-engine, four-door mid-size SUV manufactured and marketed by the Oldsmobile division of General Motors — across three generations and as a rebadged variant of the Chevrolet Blazer and GMC Jimmy. It was the only SUV manufactured or marketed by Oldsmobile, and the first light truck offered in the United States by a GM brand other than Chevrolet or GMC since before World War II.
The Chevrolet Suburban is a full-size SUV from Chevrolet. The name started in 1934 for the 1935 U.S. model year, making it the longest continuously used automobile nameplate in production. It has traditionally been one of General Motors' most profitable vehicles. The 1935 first generation Carryall Suburban was one of the first production all-metal bodied station wagons. It now comes with three engine options: a 5.3 liter V8, 6.2 liter V8 or a 3.0 liter Inline-6 turbo diesel.
The Chevrolet Tahoe is a full-size SUV from General Motors. Chevrolet and GMC sold two different-sized SUVs under their Blazer/Jimmy model names through the early 1990s. This situation changed when GMC rebadged the full-size Jimmy as the Yukon in 1991. Chevrolet waited until 1994 to rebadge the redesigned mid-size S-10 Blazer as the Blazer, renaming the full-size Blazer as the Tahoe. The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States. The name Yukon refers to the Yukon territory of northern Canada. For the 1995 model year, the Tahoe and Yukon gained a new 4-door model slotting in size between the 2-door models and the longer wheelbase and higher passenger capacity to up to nine passengers like the Chevrolet Suburban and newly named Yukon XL.
Atlas is a name for a family of modern inline piston engines for trucks from General Motors, used in the GMT 355 and GMT360 platforms. The series debuted in 2002 with the Oldsmobile Bravada, and is also used in the Buick Rainier, the Chevrolet TrailBlazer and Colorado, the GMC Envoy and Canyon, the Hummer H3, Isuzu Ascender and i-370, and the Saab 9-7X. The engines use GM's Vortec name, and Straight-4, Straight-5, and Straight-6 engines are all part of the same family, sharing the same manufacturing equipment, rods, pistons, valves, and other parts. They feature coil-on-plug ignition systems, variable valve timing on the exhaust side, electronic throttle control, and a special oil pan with a pass-through for the half shafts in four-wheel drive vehicles. The inclusion of VVT on the exhaust camshaft side allows the Atlas series to meet emissions standards without the use of EGR, simplifying the engine design and increasing power for a broad power curve. The LL8 shares 75% of its components with the LK5 and L52; while the LK5 and L52 share 89% of their components.
The 122 engine was designed by Chevrolet and was used in a wide array of General Motors vehicles. The 122 was similar to the first two generations of the General Motors 60° V6 engine; sharing cylinder bore diameters and some parts. The 122 was available in the US beginning in 1982 for the GM J platform compact cars and S-series trucks.
The Chevrolet K5 Blazer is a full-size sport-utility vehicle that was built by General Motors. GM's smallest full-size SUV, it is part of the Chevrolet C/K truck family. Introduced to the Chevrolet line for the 1969 model year, the K5 Blazer was replaced for 1995 by the Chevrolet Tahoe. In 1970, GMC introduced its own model of the truck, called the Jimmy, which was discontinued in 1991 and replaced by the Yukon. The "Jimmy" name was chosen to reflect how GM may sound in a similar manner to how Jeep was thought to be a pronunciation of GP in the competing market. Both were short-wheelbase trucks and available with either rear- or four-wheel drive.
General Motors introduced a line of Diesel V8 engines for their C/K pickup trucks in 1982. This engine family was produced by GM through 2000, when it was replaced by the new Duramax line. AM General's subsidiary General Engine Products (GEP) still produces a military variant of this engine for the HMMWV.
The Chevrolet Kodiak and GMC TopKick are a range of medium duty trucks that were produced by the Chevrolet and GMC divisions of General Motors from 1980 to 2009. Introduced as a variant of the medium-duty C/K truck line, three generations were produced. Slotted between the C/K trucks and the GMC Brigadier Class 8 conventional, the Kodiak/TopKick were developed as a basis for vocationally-oriented trucks, including cargo haulers, dump trucks, and similar vehicles; on later generations, both cutaway and cowled-chassis variants were produced for bus use.
Regular Production Option ZR2 is a special off-road/suspension package offered by General Motors on their mid-size pickup trucks and SUVs.
It debuted in 1994 on the Chevrolet S-10 and the GMC Sonoma pickup trucks. In 1996 it was expanded to the two-door Chevrolet S-10 Blazer and later offered on the Chevrolet Tracker. The ZR2 package was gradually phased out with the S-Series pickup and SUV lines. However, it has made a comeback as an option on the 2017 Chevrolet Colorado.
The Chevrolet 90° V6 family of V6 engines began in 1978 with the Chevrolet 200 cu in (3.3 L) as the base engine for the all new 1978 Chevrolet Malibu. The original engine family was phased out in early 2014, with its final use as the 4.3 L (262 cu in) V6 engine used in Chevrolet and GMC trucks and vans. Its phaseout marks the end of an era of Chevrolet small-block engine designs dating back to the 1955 model year. A new Generation V 4.3 L (262 cu in) V6 variant entered production in late 2013, based on the LT1 small block V8 used in the 2014 Chevrolet Silverado.
The Chevrolet Van is a range of vans that was manufactured by General Motors from the 1964 to 1995 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier, the model line also replaced the panel van configuration of the Chevrolet Suburban. The model line was sold in passenger van and cargo van configurations as well as a cutaway van chassis that served as the basis for a variety of custom applications.
The third generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed under the Chevrolet and GMC brands from the 1973 to the 1991 model years, this generation is the longest-produced version of the C/K model line. Adopting the "Rounded Line" moniker by General Motors, the third-generation C/K is the second longest-produced generation of American pickup trucks.
The fourth generation of the C/K series is a range of trucks that was manufactured by General Motors. Marketed by the Chevrolet and GMC brands from the 1988 to the 2000 model years, this generation is the final version of the C/K model line. The C/K nomenclature itself became exclusive to Chevrolet, with the GMC division applying the GMC Sierra nameplate across its entire full-size pickup truck line. Internally codenamed the GMT400 platform, the fourth generation C/K was not given a word moniker. After its production, the model line would informally become known by the public as the "OBS", in reference to its GMT800 successor.
