What is a Tri-Five Chevy?
Quick Answer
Tri-Five refers to the 1955, 1956, and 1957 full-size Chevrolets, across the 150, 210, and Bel Air trims. They introduced the legendary small-block V8 and some of the most beloved styling of the decade, with the 1957 Bel Air the icon of the group.
"Tri-Five" is collector shorthand for three model years that changed Chevrolet.
The three years
1955 brought all-new styling and the first 265 small-block V8. 1956 refined it. 1957 added the fins, the bigger 283 V8, and optional Rochester Ramjet fuel injection. The Bel Air was the top trim; the 210 and 150 shared the body for less.
Why they matter
The small-block that debuted here ran for decades, and the styling, especially the 1957 Bel Air hardtop and convertible, is among the most recognizable in American car culture.
