What is a Tri Five Chevy? - 1955, 1956, & 1957 Chevrolet Identification Guide


Many who are new to the classic car world have wondered, "what is a Tri Five Chevy?" The nickname Tri Five is used to represent a specific set of classic Chevrolet vehicles, namely the iconic 1955, '56, and '57 Chevrolet cars. This includes the well-known One-Fifty, Two-Ten, Bel Air, and Nomad models, as well as lesser-known sub-models such as the Delray coupe, and Handyman, Townsman, and Beauville wagons. In this article, we'll take a detailed look back at the various configurations, paint codes, and some noteworthy optional accessories for the 1955-57 Chevy Tri Five.

1955 Tri Five Chevy


The 1955 Tri Five Chevy was an all-new redesign. Each passenger car could be had with a 235ci L6 or 265ci V8 with 3-speed manual, 3-speed manual with overdrive, or 2-speed Auto (Powerglide).


The 150 level came with the essentials and almost nothing else. It had rubber floor mat instead of
carpets, 2-spoke steering wheel with a horn button (no ring), no passenger sun visor, small hubcaps, and very little exterior trim. The ashtray, cigarette lighter, coat hooks and armrests were optional equipment.


The 210 level still had rubber mats instead of carpet, but it featured stainless window trim, moderate exterior side moldings, seat moldings, glove box light, cigarette lighter, ashtray, automatic dome lights, and a horn ring.


The Bel Air came with the maximum amount of exterior chrome and bright trim, unique exterior emblems, and the full complement of interior features such as a 3-spoke steering wheel with horn ring, floor carpet, electric clock, ash trays, arm rests, etc.

1956 Tri Five Chevy


1956 Chevy Tri Five cars were 2-3 inches longer and received a new full-width front bumper, new wheel openings, and a fuel cap hidden behind the driver side tail lamp. Horsepower went up for all engines and V8s received oil filters.


The 1956 150 was spruced up with gold vinyl interior trim, bright windshield trim, and simple stainless steel side moldings. It still had rubber mats instead of carpet, and it still only had a driver side visor.


The 1956 210 was offered with new upholstery material, different exterior trim, and a "Beauville"
9-passenger wagon was added.


The 1956 Bel Air once again came with the most standard features and the greatest amount of exterior trim. A 4-door hardtop (sport sedan) was added.

1957 Tri Five Chevy

57 Chevy 1

1957 Chevy Tri Five cars were a substantial redesign, sharing only the roof, doors, and trunk with the previous years. The bumper and grille were integrated and a new gauge cluster was introduced. A 283ci V8 was offered and could be had with mechanical fuel injection. A Positraction limited slip rear axle was available for the first time.


The 1957 150 was still very plain with a bright windshield surround and minimal interior and exterior trim, but finally offered an ash tray as standard equipment.


The 1957 210 carried over all the features from previous years. Cloth and vinyl interiors were used in everything besides the Del Ray and wagon models, which were all-vinyl.


Bel Air once again came with the maximum amount of interior and exterior trim, adding gold accents for 1957.
