Chronology
Predecessor Cadillac Sixty Special
Successor Cadillac Brougham

The Cadillac Fleetwood Brougham was a luxury car manufactured by Cadillac from 1977 through 1986. In 1987, the Fleetwood Brougham name was shortened to simply Brougham, with production continuing through 1992 with only minor updates.

Contents

Cadillac used the "Fleetwood" name as a prefix between 1934 and 1976 on several of its most expensive models, always designating an elevated level of luxury. Between 1958 and 1961, Cadillac used the "Brougham" sub-designation for its exclusive four-door Eldorado models.

In 1965, the "Brougham" name was first affixed to "Fleetwood" on the Fleetwood Sixty Special as an upgraded option package, which included a vinyl roof and special "Brougham" script lettering on the sides, but it was not a separate model. In 1966, the Fleetwood Brougham was added as a separate model, accompanying the Fleetwood 60 Special, which continued through 1970. In 1971, with the Fleetwood Brougham outselling the Fleetwood 60 Special by a large margin, the two models were consolidated into a single model, the Fleetwood 60 Special Brougham, and would continue with this name through 1976. The car's name was shortened to Fleetwood Brougham with the 1977 downsizing across the GM car line. The "d'Elegance" and "Talisman" sub-models were also sometimes used to designate upgraded option packages.

Lawrence P. Fisher was the Fisher brother most closely involved with Cadillac in its early years. In 1916, he joined the Fisher Body Company, which had been formed by two of his brothers in 1908. Larry (as people knew him) was one of four of the seven Fisher brothers who brought Fisher Body Corporation under the General Motors umbrella in 1919. In May 1925, Alfred P. Sloan, then the head of General Motors, appointed Fisher as Cadillac General Manager, an office he retained through 1934. Fisher immediately went to work adding exclusive, custom bodies to the Cadillac range. Thus he oversaw the purchase of the Fleetwood Metal Body Company by the Fisher Body Corporation in September 1925. [1]

The Fleetwood Body Company of Fleetwood, Pennsylvania, was founded by Harry Urich in the nineteenth century. It began as a small community of craftsmen founded by Henry Fleetwood, Esq. of Penwortham, near Lancaster, England (the Fleetwood family flourished in England in the 17th and 18th centuries). The rich traditions of 300 years of coach-building that the Fleetwood Body Company applied to its work on cars secured for it a high reputation in automobile circles worldwide by the 1920s. Coachwork was built by Fleetwood for a variety of luxury makes through 1924. However, after the Fisher Body Corporation purchased the Fleetwood Body Company in 1925, Fleetwood bodies were reserved exclusively for Cadillac. By 1929 GM had purchased the remaining stock holdings of the Fisher Body Corporation and thus became sole owner of both the Fisher and Fleetwood companies. [1] [2]

Originally an enclosed carriage, drawn by a single horse, for 2–4 persons, “Brougham” owes its name to British statesman, Henry Brougham. Cadillac first used the name in 1916 to designate an enclosed 5-7 passenger sedan body style. [3] In the thirties, the name was given to a formal body style with open chauffeur compartment and enclosed rear quarters, metal roof and often "razor-edged" styling. [4] When Cadillac started offering Fleetwood bodies on some of its cars in 1925, the Brougham body style was Fleetwood bodied every year with the exception of 1926. After 1937 the Brougham name was not applied to any Cadillac for the remainder of the pre-WW II period. [2] [3]

The Brougham name would eventually reappear on the 1955 Cadillac Eldorado Brougham show car which preceded the 4-door Eldorado Brougham hardtops of the 1957 to 1960 model years. [3] [5] In 1957 the Cadillac Series 70 Eldorado Brougham joined the Sixty Special and the Series 75 as the only Cadillac models with Fleetwood bodies although Fleetwood script or crests did not appear anywhere on the exterior of the car, [6] [7] and so this would also mark the first time in 20 years that a Fleetwood bodied car was paired with the Brougham name. When production of the Eldorado Brougham was shifted in 1959 from the Cadillac Fleetwood plant in Detroit to Pininfarina in Turin, Italy, only then did it acquire Fleetwood wheel discs [8] and doorsill moldings, presumably because the design work [9] and final touches [6] were still being done by Fleetwood. The 1960 Eldorado Brougham would be the final iteration.

After a five year absence the Brougham name once again reappeared as an option package on the 1965 Cadillac Sixty Special. The following year the Brougham moved up to becoming a subseries of the Fleetwood Sixty Special. This continued through 1970. Starting in 1971 the Sixty Special was only available as the well equipped Fleetwood Sixty Special Brougham. [3] [5]

When the Sixty Special Series was retired in 1977, the Fleetwood Brougham took its place as Cadillac's largest owner-driven sedan model through 1986. [3] [10]

Fleetwood Brougham

For 1977, GM significantly downsized their full sized cars. The DeVille and Fleetwood Brougham rode on the same 121.5" wheelbase and were powered by the 425 cubic inch (7.0L) V8. This engine was basically a de-bored version of the 472/500 (7.9 L/8.2 L) V8 of previous years. Compared with the 1976 Fleetwood Sixty Special Brougham, the Fleetwood Brougham had a wheelbase 11.5" shorter and weighed nearly 900 lb (400 kg) less. The new Fleetwood Brougham, which had lost its exclusive longer wheelbase, was now virtually identical to the lesser Sedan de Ville. Other than the name, there were only subtle exterior differences between a Fleetwood Brougham and Sedan de Ville. The interior of the Fleetwood was more plush and offered more features as standard.

In 1980, GM gave all of the full-sized B and C-body line new sheet metal to tidy up the styling and improve aerodynamics. The basic dashboard design was retained. Also new for 1980 was a two-door Fleetwood Brougham Coupe, which was based upon the Coupe de Ville but featured an exclusive formal landau vinyl roof. The 425 cu in (7.0 L) engine, a reduced bore 472, was further debored for 1980-81 to 368 cubic inches or 6.0 liters in order to comply with newly-enacted CAFE standards. For 1981, the 368 was provided with a modulated displacement system designed by Eaton Corporation, controlled by a digital computer, which locked off intake and exhaust valves to two or four of the eight cylinders, thus running effectively as a V6 or V4 under light load conditions where in third gear, and over 35 mph (56 km/h). This engine, called the "V8-6-4", was reliable, but the computer technology of the era was not refined enough for smooth operation and it was dropped from all models but limousines after 1981.

Both the 425 and 368 are small-bore versions of the durable 472 (which was introduced in late 1967 for the '68 model year). The larger 500 had the 472's bore but a longer stroke. This engine family was the last Cadillac cast-iron engine, and the last 'big-block'. During this period, an assortment of engines were offered in the interest of fuel economy. These included the Buick 252 V6, diesel Oldsmobile 350 V8, and of Cadillac's own "HT-4100" small block V8, an alloy unit with cast iron cylinder liners which was troublesome and prone to early failure. The first two were dropped in 1982 once gas prices began falling while the latter persisted through 1986.

For 1985, Cadillac introduced a brand-new front-wheel drive platform for DeVille and Fleetwood. This car featured two "firsts"; it had the first transverse mounted V8 ever (the HT4100) and it was the first car to have a high mounted rear stop-lamp that was federally mandated starting in the 1986 model year. The rear wheel drive 1985 Cadillac Fleetwood Brougham continued on nearly unchanged from the 1984 model. 1985 was the final model year for the Fleetwood Brougham coupe. In 1986, the HT-4100 V8 was replaced with an Oldsmobile-sourced 307 cubic inch (5.0 L) V8 in the Fleetwood Brougham.

1988 Cadillac Brougham

The Fleetwood name was dropped from the Fleetwood Brougham in 1987, which continued to be produced as simply the Cadillac Brougham. It was otherwise the same as the 1986 model. The reason for the change was that Cadillac had introduced a new, smaller, front-wheel drive model in 1985 and named it simply the Fleetwood. The Brougham remained in production through 1992.

The Series 72 and 67 were similar to the Series 75 but the 72 and 67 were produced on a slightly shorter and longer wheelbase respectively. The Series 72 was only produced in 1940 and the Series 67 was only produced in 1941 and 1942.

It was built at the Cass Street and Amsterdam Avenue factory in Detroit, with the body provided by a number of coachbuilders, including Fleetwood Metal Body in Fleetwood, Pennsylvania.

Cadillac de Ville series Car model

The Cadillac DeVille was originally a trim level and later a separate model produced by Cadillac. The first car to bear the name was the 1949 Coupe de Ville, a pillarless two-door hardtop body style with a prestige trim level above that of the Series 62 luxury coupe. The last model to be formally known as a DeVille was the 2005 Cadillac DeVille, a full-size sedan, the largest car in the Cadillac model range at the time. The next year, the DeVille was officially renamed the Cadillac DTS.

Cadillac V-12

The Cadillac V-12 is a top-of-the-line car that was manufactured by Cadillac from the 1931 through the 1937 model years. All were furnished with custom bodies, and the car was built in relatively small numbers. A total of 10,903 were made in the seven model years that the automobile was built, with the majority having been constructed in its inaugural year. It was Cadillac's first, and is to date, Cadillac's only standard production V-12 powered car.

Cadillac High Technology engine

The Cadillac High Technology Engine was a V8 engine produced by the Cadillac division of General Motors from 1982 to 1995.

The Oldsmobile Model 30, also known as the Oldsmobile Six, was built from the 1923 through 1927. Each year it was built, it was given the suffix 30-A, 30-B, 30-C, 30-D and 30-E for the last year of production, all having been manufactured in Lansing, Michigan. General Motors used the General Motors B platform, shared with the Buick Master Six. The Model 30 was Oldsmobile mid-level product and introduced the flathead Oldsmobile straight-6 engine, while the Oldsmobile Model 43 with a four cylinder engine remained the entry level product. When the top level Oldsmobile Light Eight, with the flathead Oldsmobile V8 engine was cancelled in 1923, the Oldsmobile Six became the top level vehicle. It replaced the Oldsmobile Model 37 introduced in 1917, and was replaced by the Oldsmobile F-Series introduced in 1928. In 5 years, 236,474 cars were built. The growing popularity of GM's brands, like Oldsmobile, contributed to becoming the largest automobile manufacturer when sales overtook the Ford Motor Company during this time period. Coachwork for the various bodystyles were supplied by Fisher Body of Detroit, MI, and starting with the 1923 model year, all GM products adopted a shared appearance, with brand specific unique appearance features.
