The Chevrolet S-10 pickup (and its GMC Sonoma twin) did offer four-cylinder engines during its long production run, primarily the 2.2-liter inline-four and the 2.5-liter inline-four; some late-model versions also used a 2.4-liter four-cylinder. Availability varied by year and trim, so specific details depend on the exact truck in question.
Overview of four-cylinder options
The S-10/Sonoma lineup included multiple four-cylinder families. The following bullets highlight the main options that appeared across different years and configurations. For a precise match to a given vehicle, check the VIN/RPO codes or the window sticker.
- 2.2-liter inline-four (I4)
- 2.5-liter inline-four (I4)
- 2.4-liter inline-four (I4) — available in select late-model years
The above items represent the core four-cylinder choices found in S-10/Sonoma trucks over their production life. Always verify with the specific vehicle’s documentation when shopping or restoring.
How to verify a specific S-10 has a four-cylinder
If you’re shopping for a four-cylinder S-10 or trying to confirm an existing vehicle, use these verification steps. They help ensure you’re getting the intended engine configuration.
- Check the engine code stamped on the engine block and cross-check with the vehicle’s VIN and RPO codes to confirm the engine family.
- Inspect the engine bay decals or the glovebox/window sticker for the listed engine option (2.2L, 2.5L, or 2.4L).
- Consult the owner’s manual or factory window sticker for the original engine specification and options.
Confirming the exact engine is important for parts compatibility, maintenance planning, and fuel economy expectations.
Notes on performance and configuration
Four-cylinder S-10s generally offered lighter curb weights and better city fuel economy than their V6 counterparts, at the cost of lower towing capacity and slower acceleration. Transmission options varied, with typical pairings including manual and automatic choices depending on year and trim. Engine versatility across generations reflects GM’s broader compact-truck strategy of balancing efficiency with capability.
Summary
Yes, there are four-cylinder S-10s. The primary four-cylinder options were the 2.2-liter and 2.5-liter inline-fours, with a 2.4-liter four appearing in some late-model cases. Engine availability depended on the year, trim, and market, so verifying the exact configuration on any given truck is essential.
What year is S-10 to stay away from?
There isn't a year of an S10 or generation that you should avoid. They're a reliable compact truck. As someone with a fairly high optioned 99 s10, this is accurate. There's so much oddball crap on that truck it's a little aggravating.
How much horsepower does a 4-cylinder S-10 have?
120-horsepower
A 120-horsepower 2.2-liter four-cylinder engine is standard on two-wheel-drive models, but most buyers choose the 4.3-liter V-6, which is standard on four-wheel-drive models and optional on 2WD models.
