## Key facts
- Make: Chevrolet
- Model: Bel Air
- Generation: Tri-Five, 1955-1957
- Years: 1955 to 1957
- Body styles: 2-door Sport Coupe (hardtop), 2-door convertible, 4-door sedan, 2-door sedan, 4-door Sport Sedan hardtop (1956-1957), 2-door Nomad wagon, 4-door Beauville (1955) / Townsman (1956-1957) wagon
- Engines: 265 cubic inch small-block V8 with two-barrel carburetor, 162 hp (1955); Power Pack four-barrel version 180 hp; 265 cubic inch V8, top 1956 option 240 hp with the R.P.O. 411 Super Power Pack; base rating disputed, see production and spec claims; 283 cubic inch V8, 245 hp (1957, as listed for the convertible by GM Heritage); 283 cubic inch Rochester fuel-injected V8, 283 hp (1957), a $550 option; Six-cylinder base engine in all three years; output not itemized in the sources consulted
- Production notes: No source consulted gives one agreed production figure for the Bel Air across 1955 to 1957, so no total is stated. Classic Industries publishes body-style tables for each year; for 1955 they add up to 800,968 Bel Airs, the same Bel Air figure the Tri-Five encyclopedia entry gives, and for 1956 and 1957 the listed body styles add up to 650,647 and 720,356. Classic Industries says plainly that the factory has not verified its numbers and that they are estimates, and the sources that give the same lines disagree with it. The 1957 convertible is 48,068 per Classic Industries, 47,562 per Oldride and about 47,000 per GM Heritage. The 1957 four-door sedan is 264,449 per Classic Industries and 254,331 per Oldride. The Nomad is 8,530 for 1955 and 8,103 for 1956 per Classic Industries, against 6,103 to 7,886 in the Tri-Five entry and 7,886 for 1956 in the Bel Air entry. Whether the Tri-Five range is per year or combined is not stated. For context, the 150 and 210 siblings in 1955 were 143,013 and 831,971 per the Tri-Five entry, and total Chevrolet output was 1,775,952 in 1955, 1,623,376 in 1956 and 1,555,316 in 1957 per Classic Industries. No source separates V8 from six-cylinder Bel Airs, US cars from exports, or counts the 1957 fuel-injected cars. No US-market price list for 1955 or 1956 Bel Air models was retrieved, so only the 1957 and 1955 Nomad prices appear here.

## Summary
The Bel Air was the top trim of Chevrolet's 1955 to 1957 line, the cars collectors call the Tri-Five, with the 150 and 210 below it. The 1955 redesign brought a new 265 cubic inch overhead-valve V8 rated at 162 hp with a two-barrel carburetor, 180 hp with the Power Pack, and the engine stayed in production in various displacements for decades. The 1956 car took a face-lift with a full-width grille, and 1957 brought the 283 at 245 hp and a fuel-injected 283 rated at 283 hp, a $550 option. A 1957 Bel Air convertible listed at $2,611 with a V8. Production is not agreed: Classic Industries tables, which it calls unverified estimates, put 1955 Bel Air output at 800,968, but its convertible and Nomad figures conflict with other sources. As of September 2026 OldCarsData reports a median of $39,000 for 1957 Tri-5 sales, with a range from $5,000 to $180,000 across all models.

- Nomad (two-door wagon): A 1954 Motorama show car turned into a production wagon, the only two-door Chevrolet wagon with carpeting and cloth seats, and the only one with Corvette-style radiused rear wheel openings. Production figures conflict by source.
- 1957 fuel-injected V8 (283 hp): A $550 option and the first production engine rated at one horsepower per cubic inch; no source retrieved counts how many Bel Airs received it.
- Four-door Sport Sedan (1956-1957): A pillarless four-door hardtop added for 1956; Classic Industries lists 109,261 for 1956 and 142,518 for 1957, as estimates.
- Bel Air four-door sedan: The volume car by a wide margin, at 366,293 for 1955 per Classic Industries, and the shape most often found as a driver-grade car at auction.

## History

### Why the Bel Air exists

In 1953 Chevrolet decided it was time to update the first-generation Bel Air to reflect the newest technology of the post-war era, and the 1955 car was the result. Chevrolet dropped the torque tube drive and the split windshield, and the headline was an all-new 265 cubic inch overhead-valve V8, a high-compression, short-stroke design that stayed in production in various displacements for many decades. GM's advertising called it the Hot One. The Bel Air sat at the top of a three-tier line: the 150 at 143,013 cars in 1955, the 210 at 831,971, and the Bel Air at 800,968, per the Tri-Five entry. The subject of this page is the top tier, not the cheaper two.

### 1955: the V8 arrives

The base V8 was rated at 162 hp with a two-barrel carburetor, and the Power Pack four-barrel option raised that to 180 hp. A museum page cites contemporary testing at 12.9 seconds to 60 mph for the V8 against 19.6 seconds for the six, though that is one low-reliability source. The 1955 Bel Air weighed 3,456 lb and measured 16 feet in length. Classic Industries counts 366,293 four-door sedans, 189,269 Sport Coupes, 168,826 two-door sedans and 42,278 convertibles, all of which it describes as unverified estimates.

### The Nomad: a show car in the showroom

The Nomad began as a 1954 Motorama show car developed under GM head stylist Harley Earl. In production it was the only two-door Chevrolet wagon with interior carpeting and cloth seats, and it carried the radiused rear wheel openings that Chevrolet also used on the Corvette. It listed at $2,571 in 1955, among the most expensive Chevrolets other than the Corvette. It is also the model on this page where the numbers fight hardest: Classic Industries lists 8,530 for 1955, while the Tri-Five entry gives 6,103 to 7,886. The disagreement is covered in the production notes and is not settled by any source retrieved.

### 1956 and 1957: facelift, then displacement

The 1956 Bel Air took a face-lift with a more conventional full-width grille, and a four-door Sport Sedan hardtop joined the line. The engine ratings that year are unclear in the sources: one entry says the base 265 rose from 170 to 185 hp with a 240 hp Super Power Pack at the top, while a 1956 auction lot lists the 265 at 162 hp. For 1957 the small-block grew to 283 cubic inches at 245 hp, and the Rochester fuel-injected 283 was rated at 283 hp, described as the first production engine to reach one horsepower per cubic inch. Fuel injection was a $550 option. A 1957 convertible started at $2,611 with the V8 or $2,511 with the six, and the base two-door sedan at $2,338 or $2,238. GM Heritage describes one 1957 convertible built at the Los Angeles plant and says about 47,000 convertibles were built that year, a number two other sources put at 47,562 and 48,068.

### What the record does not say

No US period road test was retrieved for this page, and no source consulted gives torque, transmission offerings, or a US price list for 1955 and 1956 Bel Airs. Total Chevrolet output was 1,775,952 in 1955, 1,623,376 in 1956 and 1,555,316 in 1957 per Classic Industries, so the Bel Air was one tier of a line that sold well over a million and a half cars a year.

## What to look for

Start with which Bel Air it is. The 1955 to 1957 Chevrolets are sold in huge numbers as 150, 210 and Bel Air, and the Bel Air is the top trim, so trim and body style should be confirmed against the car rather than the listing. The engine needs the same scrutiny: a 1957 car may carry the 245 hp 283, or the 283 hp fuel-injected version that was a $550 option, and no source consulted counts how many fuel-injected Bel Airs were built, so documentation matters. Rust is the main body concern, and owners of 1955 cars report it in the lower fender drops and around the wheelwells, the inner and outer rocker panels, the floor pans where they meet the rear inner wheel wells, the bottom of the trunk, the rear panel between the wheel opening and the bumper, the firewall braces where they attach to the frame, the headlight buckets and eyebrows, and the bottom edges of the doors. One owner suggests a refrigerator magnet to find filler, because it will not scratch paint, and a flashlight under the car. Regional history matters: forum owners say southwest cars may have manageable rust while rustbelt or coastal cars often carry filler on the lower sections. A stored car can also hide age-related faults; a 1956 sedan sold in November 2024 after 42 years in heated storage still had pitted chrome, corrosion around the top of the windshield and dark spots on the headliner.

## Common problems

The evidence retrieved for this car is about rust and age, not mechanical faults. Owners of 1955 Chevrolets report rust in the lower fender drops and around the wheelwells, the kick panels, the inner and outer rocker panels, the floor pans, the bottom of the trunk near the wheel wells, the rear panel between the wheel opening and the bumper, and the headlight buckets. They also report filler built up on the bottom edges of the doors and drainage channels behind the door bottoms on hardtops. A 1956 four-door sedan sold at auction after 42 years in heated storage showed pitted chrome in several areas, corrosion around the top of the windshield, small rust spots on the front bumper and dark spots on the headliner. Owners on a forum, a low-reliability source, say southwest cars may have manageable rust and rustbelt or coastal cars often have filler smeared over the lower parts. No NHTSA recall, technical service bulletin or US specialist repair cost for these cars was retrieved, so no mechanical failure rate or repair cost is stated here; the engine, fuel-injection and drivetrain weak points are an open gap on this page.

## Market notes

As of September 2026 the sources retrieved for this page give only broad market figures, not a Bel Air generation benchmark. OldCarsData reports a median sale price of $39,000 across 43 year-specific sales in the last 12 months of 1957 Tri-5 Chevrolets, with observed prices from $5,000 to $180,000; that covers every Tri-5 model, so 150 and 210 cars sit in the same pool as Bel Air convertibles and Nomads. classic.com shows an overall Bel Air average sale price of $66,754 and 223 second-generation cars listed for sale, and its lowest recorded sale is $550 for a 1957 car in October 2022. classic.com's own pages put pricing history behind a paywall, so no price is quoted from an individual listing. One individual result is available: a 1956 Bel Air four-door sedan with a 265 V8, 98,351 miles of unknown true mileage and 42 years in heated storage sold on Hagerty Marketplace for $18,190 on November 7, 2024, with pitted chrome and corrosion around the top of the windshield noted. That is the only dated, individually sourced sale here, and a four-door sedan in storage condition says little about Sport Coupes, convertibles or Nomads. No Hagerty valuation guide, Bring a Trailer result or auction-house lot for a convertible, Nomad or fuel-injected 1957 car was retrieved.

## Value trajectory

The retrieved sources do not support a trajectory over time, and none is invented here. As of September 2026 they give a spread: OldCarsData's 1957 Tri-5 median of $39,000 with a range from $5,000 to $180,000, classic.com's overall Bel Air average of $66,754 across all Bel Air generations with a lowest recorded sale of $550 in October 2022, and a single 1956 four-door sedan that sold for $18,190 in November 2024. Set against a $2,611 list price for a 1957 V8 convertible, those figures show a car that has long since finished depreciating, but the sources retrieved do not separate convertibles, Sport Coupes, Nomads or fuel-injected cars from four-door sedans, so the premium for any of them is not quantified here. The width of the range is itself the finding: a project car and a fully restored custom differ by a factor of dozens, and the model-year and body-style pricing that a buyer would need is behind paywalls that could not be fetched.
