In automobile parlance, Tri-Five refers to the 1955, 1956 and 1957 Chevrolet automobiles, in particular, the 150, 210, Bel Air, and Nomad. [1] Revolutionary in their day, they spawned a devoted following that exists in clubs, websites and even entire businesses that exclusively cater to the enthusiasts of the Tri Five automobiles. All featured a common for the era front-engine, rear-wheel-drive layout. They remain some of the most popular years of Chevrolets for collectors, (resto-)modders, and hot-rodders. [2] [3]
One of the most influential elements of the Tri-Five was the recent development of their newest 265 cid (4,340 cc) V8 engine, which was first offered in 1955. [4] It was an overhead valve high compression, short stroke design that remained in production in various forms for decades. The base V8 had a two-barrel carburetor and was rated at 162 horsepower (121 kW), and the "Power Pack" option featured a four-barrel carburetor and other upgrades yielding 180 brake horsepower (130 kW). Later, a "Super Power Pack" option added high compression and a further 15 brake horsepower (11 kW). [5]
1955-1957 were watershed years for Chevrolet, who spent a million dollars in 1956 alone for retooling, in order to make their less expensive Bel Air models look more like a Cadillac, culminating in 1957 with their most extravagant tailfins and Cadillac inspired bumper guards. [4]

In 1955, Americans purchased 7.1 million new automobiles, including 1.7 million Chevrolets, giving the company fully 44% of the low-price market [7] and surpassing Ford in total unit sales by 250,000. [8] The Bel Air was an instant hit with consumers, with a minimally equipped One-Fifty models starting under $1600 and featuring a six cylinder engine. [9] The introduction of the new optional 162 horsepower Chevrolet 265 cid V8, coupled with the Powerglide automatic transmission quickly earned the model the nickname "The Hot One". In the first year of production, the oil filter was considered an option, although not having it led to significantly shorter engine life. [9]
1955 also saw the introduction of the Chevrolet Nomad sport wagon. Introduced mid-year, somewhere between 6103 [10] and 7886 [8] were produced in 1955, making them more rare. It was available only in the Bel Air trim with the V8 as standard equipment. Priced at $2571, it was at the higher end of the Chevrolet pricing scale but came standard with plush carpeting, two-toned paint, headliner trim and other features that separated it from the most basic 150 Series Chevrolets. [10]
1956 was basically a carry over model, with minor changes to the grill, trim and other accessories. It meant huge gains in sales for Chevrolet, who sold 104,849 Bel Air models, due in part to the new V8 engine introduced a year before. [11] By this time, their 265cid V8 had gained popularity with hot rodders who found the engine easy to modify for horsepower gains. This wasn't lost on Chevrolet's engineers, who managed to up the horsepower in 1956 from 162 hp to 225 hp with optional add-ons. [12] For 1956 the 265 cid V8 engine was modified to include an integral oil filter, with a range of power choices from 162 HP for the base V8 up to 240 HP for R.P.O. 411 "Super Power Pack" offered mid-year. [13] [14] [15]
The average two door Bel Air in 1956 sold for $2100, which was considered a good value at the time. Prices ranging from $1665 for the 150 sedan with six cylinder engine to $2443 for the V8 equipped convertible, with Nomad models running slightly higher. [16]
In 1956, Zora Arkus-Duntov broke the time record ascending Pikes Peak in a pre-production 1956 Bel Air equipped with the 265 V8 engine in just 17 minutes and 24.05 seconds, shattering the previous record of 19 minutes 25.70 seconds, set 21 years before. [17]
The last of the Tri-Five Chevrolets introduced several changes, including the large tailfins, "twin rocket" hood design, even more chrome, tri-color paint and a choice from no less than seven different V8 engines. [17] While in 1957, Ford outsold Chevrolet for the first time in a great while, years later the used 1957 Chevrolets would sell for hundreds more than their Ford counterparts. [18] As the horsepower race continued, Chevrolet introduced a new version of their small block, with 283 cubic inches of displacement and 245 horsepower. They also introduced a limited number of Rochester fuel injected 283 engines that produced 283 horsepower, the first production engine to achieve 1 horsepower per cubic inch. [19] For all intent and purposes, this made the 1957 Bel Air a "hot rod", right off the production line. [17] It was available with manual transmission only. The base 265cid engine saw an increase from 170 to 185 horsepower as well. While not as popular as the previous year's offering, Chevrolet still managed to sell 1.5 million cars in 1957. [20] Even now, the 1957 Chevrolet Bel Air is one of the most sought after collector cars ever produced. [17]
Although considered classics, the Tri-Five in recent years have been seen as among the most dangerous vehicles to drive, especially in comparison to modern vehicles. In 2009, the Insurance Institute for Highway Safety released a crash-test video between a 1959 Bel Air (though not a Tri-Five model) and a 2009 Chevrolet Malibu in a head-on collision. The Bel Air scored a "Poor" rating in every category and collapsed internally in comparison to the Malibu. [21] In 2017, Car and Driver wrote a piece detailing what would make the Tri-Five unsafe even for its day. [22]
Pontiac, or formally the Pontiac Motor Division of General Motors, was an American automobile brand owned, manufactured, and commercialized by General Motors. It was originally introduced as a companion make for GM's more expensive line of Oakland automobiles. Pontiac quickly overtook Oakland in popularity and supplanted its parent entirely by 1933, in turn establishing its position as one of GM's dominant divisions.
The Chevrolet Chevelle is a mid-sized automobile that was produced by Chevrolet in three generations for the 1964 through 1977 model years. Part of the General Motors (GM) A-body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles included coupes, sedans, convertibles, and station wagons. The "Super Sport" versions were produced through the 1973 model year and Lagunas from 1973 through to 1976.
The Chevrolet Bel Air is a full-size car produced by Chevrolet for the 1950–1981 model years. Initially, only the two-door hardtops in the Chevrolet model range were designated with the Bel Air name from 1950 to 1952. With the 1953 model year, the Bel Air name was changed from a designation for a unique body shape to a premium level of trim applied across a number of body styles. The Bel Air continued with various other trim level designations, and it had gone from a mid-level trim car to a budget fleet sedan when U.S. production ceased in 1975. Production continued in Canada, for its home market only, through the 1981 model year.
The Pontiac Catalina is a full-size, junior series automobile produced by Pontiac from 1950 to 1981. Initially, the name was a trim line on hardtop body styles, first appearing in the 1950 Chieftain Eight and DeLuxe Eight lines. In 1959, it became a separate model as the "entry-level" full-size Pontiac.
The Y-block engine is a family of overhead valve V8 automobile engines produced by Ford Motor Company. The engine is well known and named for its deep skirting, which causes the engine block to resemble a Y. It was introduced in 1954 as a more modern replacement for the outdated side-valved Ford Flathead V8 and was used in a variety of Ford vehicles through 1964.
The Chevrolet Delray, named after the Delray neighborhood of Detroit, Michigan, debuted in 1954 as an optional trim level on two-door models of Chevrolet's mid-range 210 series of cars. In 1958, it became a distinct series of its own at the bottom of Chevrolet's lineup, and added a four-door sedan, and sedan delivery, but it only remained in production for that model year.
The Chevrolet Brookwood is a series of full-size station wagons produced by Chevrolet from 1958 to 1961, and again from 1969 to 1972. It debuted in 1958 as Chevrolet's mid-range model in its station wagon lineup, positioned between the less expensive Yeoman and more luxurious Nomad station wagons. After the Yeoman was discontinued in 1959, the Brookwood was subsequently demoted to entry-level status, before going out of production altogether in 1961. It made a brief reappearance from 1969 and 1972, once again as the least-expensive wagon in Chevrolet's lineup.
The 1957 Chevrolet is a car that was introduced by Chevrolet in September 1956 for the 1957 model year. It was available in three series models: the upscale Bel Air, the mid-range Two-Ten, and the One-Fifty. A two-door station wagon, the Nomad, was produced as a Bel Air model. An upscale trim option called the Delray was available for Two-Ten 2-door sedans. It is a popular and sought after classic car. These vehicles are often restored to their original condition and sometimes modified. The car's image has been frequently used in toys, graphics, music, movies, and television. The '57 Chevy, as it is often known, is an auto icon.
The Pontiac Chieftain is an automobile which was produced by Pontiac from 1949 to 1958. The 1949 Chieftain and Streamliner models were the first all new car designs to come from Pontiac in the post World War II years. Previous cars had been 1942 models with minor revisions.
Chevrolet Nomad is a nameplate used by Chevrolet in North America from the 1950s to the 1970s, applied largely to station wagons. Three different Nomads were produced as a distinct model line, with Chevrolet subsequently using the name as a trim package.
The Chevrolet Corvette (C1) is the first generation of the Corvette sports car produced by Chevrolet. It was introduced late in the 1953 model year and produced through 1962. This generation is commonly referred to as the "solid-axle" generation, as the independent rear suspension did not appear until the 1963 Sting Ray.
The Rambler Rebel is an automobile that was produced by the American Motors Corporation (AMC) of Kenosha, Wisconsin for the 1957 through 1960 model years, as well as again for 1966 and 1967.
The Chevrolet One-Fifty was the economy/fleet model of the Chevrolet car from 1953 until 1957. It took its name by shortening the production series number (1500) by one digit in order to capitalize on the numerical auto name trend of the 1950s. The numerical designation "150" was also sporadically used in company literature. It replaced the Styleline Special model available in previous years. This model was discontinued following the 1957 model year and replaced by the Delray.
The 1955 Ford is an automobile which was produced by Ford in the United States for the 1955 model year and, in revised form, for the 1956 model year. A new design would be offered in 1957.
The Chevrolet Beauville was originally a station wagon option for the 1954 Chevrolet Bel Air. The name was later resurrected as a full-size van option for the Chevrolet Van in 1970. Both were related to the lower trim level Chevrolet Townsman.
The Chevrolet 210 or Two-Ten is a midrange car from Chevrolet that was marketed from 1953 until 1957. It took its name by shortening the production series number 2100 by one digit in order to capitalize on the 1950s trend toward numerical auto names. The numerical designation "210" was also sporadically used in company literature. It replaced the Styleline DeLuxe model available in previous years. The 210 was discontinued after the 1957 model year to be replaced by the Biscayne.
The first generation of the Ford Thunderbird is a two-seat convertible produced by Ford for the 1955 to the 1957 model years, the first 2-seat Ford since 1938. It was developed in response to the 1953 Motorama display at the New York Auto Show, which showed the Chevrolet Corvette. The Corvette in turn was developed in response to the popularity of European sports cars among Americans.
The 1955 Chevrolet is an automobile which was introduced by Chevrolet in Autumn 1954 for the 1955 model year. It is considered a huge turning point for the manufacturer and a major success. It was available in three models: the 150, 210, and Bel Air.
The Chevrolet Impala (fourth generation) are full-size automobiles produced by Chevrolet for the 1965 through 1970 model years. The 1965 Impala was all new, while the 1967 and 1969 models featured new bodies on the same redesigned perimeter frame introduced on the 1965 models. All Impalas of this generation received annual facelifts as well, distinguishing each model year. Throughout the early 1960s, Chevrolet's basic body designs became increasingly subtle, while the bright trim that was part of the Impala package added more than a touch of luxury to the look. The same pattern was followed in the interiors, where the best materials and equipment Chevrolet had to offer were displayed. In short, the Impala was on its way to becoming a kind of junior-grade Cadillac, which, for both the company and its customers, was just fine.
The 1950s were pivotal for the American automobile industry. The post-World War II era brought a wide range of new technologies to the automobile consumer, and a host of problems for the independent automobile manufacturers. The industry was maturing in an era of rapid technological change; mass production and the benefits from economies of scale led to innovative designs and greater profits, but stiff competition between the automakers. By the end of the decade, the industry had reshaped itself into the Big Three, Studebaker, and AMC. The age of small independent automakers was nearly over, as most of them either consolidated or went out of business.
