The 1981 Chevrolet S10 Blazer, a compact sport utility vehicle (SUV), marked the beginning of a new era for Chevrolet, ushering in the first generation of the iconic S10 platform. This generation, produced from 1982 to 1991, saw the S10 Blazer become a popular choice for its versatility, affordability, and rugged capabilities. Sharing its underpinnings with the Chevrolet S10 pickup truck, the Blazer offered a blend of car-like handling and off-road prowess, making it a practical choice for both urban and rural environments. Under the hood, it was powered by a 2.5-liter four-cylinder engine or a 2.8-liter V6, offering a balance of fuel efficiency and performance. The S10 Blazer's interior was simple and functional, offering comfortable seating for five occupants and a decent cargo space.

The 1981 S10 Blazer, however, was technically part of the previous generation, spanning from 1972 to 1981. These early Blazers were built on a modified Chevrolet Nova platform, inheriting the same chassis and styling. This generation was more focused on its car-like handling and comfort, offering a smaller and lighter package compared to its bigger siblings. Power came from a 2.5-liter four-cylinder engine or a 3.8-liter V6, both paired with a three-speed automatic or a four-speed manual transmission. While not as rugged as its later counterparts, the 1981 S10 Blazer offered a practical and affordable alternative to larger SUVs. The 1981 S10 Blazer's popularity solidified Chevrolet's position in the emerging SUV market, setting the stage for its continued success in the coming years.
