No, Chevy S10 and GMC Sonoma are not the same thing. Though they had similar designs and shared components, these two pickup trucks were distinct models with different features under the hood. The Chevrolet S10 was introduced in 1982 as a compact pickup truck built by General Motors. It was available in both 2-door and 4-door body styles with rear-wheel or 4WD drivetrains. Its engine options ranged from an inline four to a V6 powerplant. On the other hand, GMC Sonoma first appeared in 1983 as part of the brand's mid-size lineup of pickups. The vehicle featured a longer wheelbase than its Chevy counterpart but maintained most of its design elements such as cab size and exterior styling cues. Underneath its sheet metal, however, it was powered exclusively by six engines ranging from 2.0L to 4.3L displacement capacities paired with either manual or automatic transmission systems depending on trim level selection. Therefore, while there may be similarities between them due to their common roots at General Motors Company (GMC), Chevy S10 and GMC Sonoma remain two distinct vehicles that offer varying characteristics for consumers looking for reliable transportation solutions
