The Chevrolet Blazer and GMC Jimmy names were used on two different early SUV models:The full-size K5 Blazer and Jimmy were produced from 1969 on the C/K pickup truck chassis
The Chevrolet Blazer was one of the most popular SUVs for five consecutive decades, though its name was shared by two completely unrelated model lines. Chevrolet first started affixing the "K5 Blazer" designation to two-door convertible SUV versions of its big trucks starting in 1969.
Today, most of the old-school K5 Blazers have long since rusted away or have otherwise been reclaimed by off-roading enthusiasts. Chevy continued to produce full-size, two-door Blazers through 1994, after which it rechristened these vehicles with the now-current Tahoe name.
In the early 1980s, however, Chevrolet started to call another one of its products the Blazer. And in actuality, the other Chevy Blazer -- the "S-10 Blazer" -- is the one consumers are most likely to come across in the used-car market due to its greater popularity and more recent place in history.
Born as a variant of Chevrolet's S-10 compact pickup in 1983, this S-10 Blazer was a pioneer of the modern small-SUV segment. Though initially limited in terms of body styles and often underpowered, it did eventually receive four doors and better engines. A redesigned second-generation model (without the S-10 moniker) arrived in 1995 with improvements in performance, styling and interior room.
