From 1982 to 2004, Chevrolet and GMC significantly shaped the compact truck and SUV markets with their S10, S15 (later Sonoma), Blazer, and Jimmy models. These vehicles were lauded for their practicality, versatility, and efficiency, serving a wide range of consumer needs from daily commuting to off-road adventure.

Launch and Evolution

Chevrolet S10 and GMC S15/Sonoma: Launched in 1982, the Chevrolet S10 and GMC S15 introduced American consumers to the compact truck segment. The GMC S15 was renamed the Sonoma in 1991. These models saw several redesigns throughout their production, particularly in 1994 and again in 1998, improving their style, engine offerings, and in-cab technology to keep pace with evolving consumer expectations.

Chevrolet Blazer and GMC Jimmy: Based on the truck platforms, these compact SUVs debuted in 1983, blending the utility of pickups with the passenger comfort of an SUV. Like their truck counterparts, the Blazer and Jimmy evolved to offer more refined amenities and stronger performance capabilities, especially following substantial redesigns in 1995.

Engine and Transmission Specifications

Engine Offerings:

• 1982-1993: Early models featured 2.0L and 2.8L four-cylinder engines. The introduction of the 4.3L V6 in 1988 provided a more robust option that balanced power with reasonable fuel economy.
• 1994-2004: The 4.3L V6 became standard across the lineup, noted for its durability and performance in varied driving conditions. Diesel engines, like the 2.2L offered in the early '90s, presented alternatives focused on fuel efficiency.

Transmission Types:

• 1982-1993: Initially offered with 4-speed manual and 3-speed automatic transmissions.
• 1994-2004: Upgrades included 5-speed manual and 4-speed automatic transmissions, enhancing both driving comfort and fuel efficiency.

Special Models and Significant Year Changes

High-Performance and Luxury Variants:

• S10 Xtreme (1999-2004): Targeted at enthusiasts seeking a sportier aesthetic, featuring a lowered suspension, special body kits, and unique styling.
• Sonoma GT (1992-1993) and Syclone (1991): The Sonoma GT provided a sportier ride with upgraded features, while the Syclone was a high-performance version equipped with a turbocharged V6 and all-wheel drive, making it extraordinarily fast for its class.
• Blazer Tahoe and Jimmy Typhoon (Early 1990s): These performance-oriented versions offered enhanced engines and sport-tuned suspensions. Notably, the Jimmy Typhoon in 1992-1993 came with a turbocharged engine similar to the Syclone.
