The 2000 Chevy S-10 could be equipped with either a 2.2-liter inline-4 or a 4.3-liter V6. The base S-10s used the 2.2L, while higher trims and configurations could be equipped with the 4.3L V6.
Engine options
Two powerplants were offered across the lineup. Below are the two configurations commonly found in 2000 S-10 pickups.
2.2-liter inline-4
The entry-level 2.2-liter four-cylinder delivered roughly 125 horsepower and about 140 pound-feet of torque. It could be paired with a five-speed manual transmission in the most basic trims, or with a four-speed automatic on more-equipped models. This engine emphasized efficiency and predictable daily performance.
4.3-liter V6
The optional 4.3-liter V6, known as the Vortec 4300, produced around 190 horsepower and about 250 pound-feet of torque. It offered stronger pulling power for towing and hauling, and was typically matched with a four-speed automatic transmission; manual options were uncommon for this engine in most configurations.
Performance and fuel economy
Performance and efficiency vary notably between the two engines. The 2.2L generally delivered better fuel economy in everyday driving, while the 4.3L V6 provided substantially more torque and towing capability at the cost of higher fuel consumption. Real-world figures depend on drivetrain (two-wheel drive vs. four-wheel drive) and the exact transmission installed.
Summary
For the 2000 Chevy S-10, the choice boiled down to a practical 2.2-liter inline-4 for economical use, or a robust 4.3-liter V6 for heavier workload needs. The right engine depended on how the truck was to be used.
