Chevrolet was one of the pioneers of the for-fun-and-work truck, a pre-cursor to the SUV. In 1983, Chevy introduced its S10 Blazer, based on the 1982 S10 pickup. (The S10 Blazer was the same as the GMC S15 Jimmy except for some cosmetic details.)
The S10 Blazer, available in 2WD or 4WD, was basically an S10 pickup with two doors and an enclosed, passenger-friendly back. It featured a tailgate that you could open for easy loading, or you could leave the tailgate closed and open the rear window, lifting it straight up.
The '83 Chevy Blazer's 2-liter, 4-cylinder engine was hardly a powerhouse with its 83 horsepower, but it went almost wherever its drivers took it - offroad, of course. A more powerful engine was available as an option: a 2.8-liter, 6-cylinder engine with 110 horsepower.
Drivers of the 4WD Blazer used the "InstaTrac" feature for "on-the-fly" four-wheel drive, so they didn't have to stop the vehicle unless they needed 4WD "low" (for especially steep or tough terrain).
