The Ambassador was the top-of-the-line automobile produced by the American Motors Corporation (AMC) from 1958 until 1974. The vehicle was known as the Ambassador V-8 by Rambler, Rambler Ambassador, and finally AMC Ambassador during its tenure in production. Previously, the name Ambassador had applied to Nash's "senior" full-size cars.
The Ambassador nameplate was used continuously from 1927 until 1974 (the name being a top-level trim line between 1927 and 1931); at the time it was discontinued, Ambassador was the longest continuously used car nameplate in automotive history.
Most Ambassador models were built in Kenosha, Wisconsin. They were also built at AMC's Brampton Assembly in Brampton, Ontario from 1963 to 1966. Australian Motor Industries (AMI) assembled Ambassadors from knock-down kits with right-hand drive from 1961 to 1963. The U.S. fifth generation Ambassadors were produced by Industrias Kaiser Argentina (IKA) in Córdoba, Argentina from 1965 to 1972, as well as assembled by ECASA in Costa Rica from 1965 to 1970. Planta REO assembled first-generation Ambassadors in Mexico at its Monterrey, Nuevo León plant. Fifth and seventh generation Ambassadors were modified into custom stretch limousines in Argentina and the U.S.
Seventh generation
1974
Ambassador sales had remained steady since 1970, despite the lack of major changes to the vehicle. However, the 1974 model year would bring out the biggest Ambassador—just as the 1973 Arab Oil Embargo sparked gasoline rationing across the nation. The Ambassador sedan was stretched seven inches (180 mm) compared with the 1973 versions. This additional length was due to a new front end design and stronger energy absorbing bumpers with hydraulic backup.
The 1974 Ambassador Brougham was no longer available as a 2-door (pillar-less) hardtop, leaving the 4-door sedan and station wagon body styles in the line. The hardtop's cancellation was due in part to low sales volume of the Ambassador 2-door versions, as well as the introduction of an all-new 1974 Matador coupe that featured a very long hood and a short rear deck. The new coupe was selected as the "Best Styled Car of 1974" by the editors of Car and Driver magazine and did not have the requisite share the typical mid- to late-1970s styling hallmarks that included an upright grille, a notchback roof, and imitation "landau bars" or opera lights.
Styling changes for the sedan and wagon included new front fender caps on the same fenders as used since 1969, and hood, grille, bumpers, rear fascia, instrument panel, interior trim, hood ornament, and a new font for the Ambassador nameplate. The grille showed off a new squared-off loop-type design surrounding the circular recessed quad headlights, and featured a forward-protruding center. The insert held a crosshatch pattern dominated by two thick horizontal bars that connected the headlight bezels and contained new parking lights between them. These parking lights had amber lenses, followed the grille protrusion forward, and were overlaid by the grille's crosshatch trim. Headlamp bezels were once again blacked out in their recessed areas. The new hood and front bumper followed the grille's central protrusion forward, giving the car a slight "coffin nose" look. The revised Matador sedan saw a similar frontal treatment in 1974, but with a much more pronounced effect and with different single headlamp clusters, hood, and grille insert.
As with the new Matador sedan, the new rear bumper was much larger and backed by shock absorbers, as it was beefed up to comply with new National Highway Traffic Safety Administration regulations for standardized front and rear bumpers on passenger cars that could sustain a 5-mile-per-hour (8 km/h) impact with no damage. Fiberglass end caps were added to the ends of each rear fender on sedans. They wrapped inward to create a recessed space that met a carryover decklid. In this space was mounted the new rectangular taillight housings, which featured taller white backup lights mounted inboard of the new taillights. The license plate moved from the rear bumper to the area between the new taillight assemblies, and the whole taillight and license plate system on the sedans was surrounded its own loop of chrome trim. Both Ambassador and Matador sedans shared the same rear end style.
The cargo area and the rear design of station wagons remained similar to previous Ambassadors, save for a massive new bumper and revised taillamps. The wagon was available with two-row bench seats for six passengers or with a rear-facing third row for a total eight seat-belted passengers. All came with numerous practical, appearance, and comfort items as standard. These included a two-way opening tail gate: (1) hinged at the bottom for convenient loading or hauling long cargo and (2) hinged at the side to open as door for ease of entry and exit for passengers or cargo; wood grained semi-transparent vinyl side and rear trim, a full-length roof rack; as well as a chrome and wood grain roof air deflector to help keep the tailgate window clean.
Powertrain selections remained the same as in 1973, with only V8 engines and automatic transmissions available. When ordered with a trailer package (special wiring harness with heavy-duty flasher and heavy-duty suspension with rear sway bar), the Ambassador was rated for up to 5,000-pound (2,268 kg) towing capacity. Other increases for 1974 included a larger capacity fuel tank, 24.9 US gal (94 L; 21 imp gal), and an alternator producing 62 amperes. New sound insulation made the Ambassador even quieter. All came with a very lengthy list of standard equipment that was typically optional on competing makes. These included comfort items such as air conditioning, an AM radio, and vanity mirror to appearance enhancements such as pin striping and whitewall tires.
Sales of all full-size vehicles, regardless of the automaker, fell significantly in 1974 as America's focus shifted to smaller cars. Ambassador sales were no different, and in June 1974, the final AMC Ambassador rolled off the Kenosha, Wisconsin assembly line, ending a nameplate that had been in continuous production in some form for 48 years.
Epilogue
Because AMC was focusing its attentions on their newly acquired Jeep line, the redesigned 1974 Matador coupe, and the AMC Pacer, which would debut in 1975, the company would not put forth the investment to continue the full-size Ambassador line after its 1974 redesign. Instead, the automaker upgraded the Matador sedan and wagon counterparts starting with the 1975 model year. The basic automobile platform was used by AMC since the 1967 model year, and the full-size automobile market segment was declining. American Motors strategy now aimed at smaller cars and sport-utility vehicles.
However, the Ambassador basically continued as the similarly sized and styled Matador sedans and wagons. From 1975 they became available in uplevel "Brougham" trim and assumed the model numbers of the previously equivalent Ambassadors. The Matador was also offered in a unique top-of-the-line Barcelona four-door in its final year of production, 1978.
