The Rambler Rebel is a series of automobiles manufactured by the American Motors Corporation (AMC) of Kenosha, Wisconsin, across two distinct periods: from 1957 through 1960 and again for the 1966 and 1967 model years.
The Rebel is significant in automotive history with its introduction for the 1957 model year as a singular, high-performance model. Available only as a four-door hardtop, it is recognized by many as having pioneering what would later be known as the "muscle car" market segment. It was among the earliest production vehicles to offer electronic fuel injection, showcasing AMC's technological initiatives.
The Rebel name was expanded for use on 1958 through 1960 Rambler models featuring a V8 engine as standard equipment. Available as sedans and station wagons in two trim levels, they largely mirrored the Rambler Six models. The Rebel nameplate was reintroduced for the 1966 model year as a premium, intermediate-sized two-door hardtop model. For the 1967 model year, AMC consolidated its newly designed intermediate line under the Rambler Rebel name. This change was pivotal for AMC. The long-standing "Rambler" marque was dropped from the intermediate-sized models, and they were rebranded as the AMC Rebel beginning with the 1968 model year.
Beyond its domestic production in Kenosha, Wisconsin, Rambler Rebel models were assembled at the former Nash Motors plant in Toronto, Canada, until the facility closed in July 1957. Canadian-market Ramblers were then imported from Kenosha until AMC established its new assembly plant in Brampton, Ontario, in December 1960. The Rebel's global reach included assembly in Belgium by Renault, in Australia by Australian Motor Industries (AMI), in New Zealand by Campbell Motor Industries, and in Argentina by Industrias Kaiser Argentina (IKA).
Background The Rambler Rebel's origins are intertwined with the strategic vision of George W. Romney, then president of AMC. Recognizing that, as a smaller, independent automaker, it could not effectively compete head-to-head with the domestic Big Three automakers (General Motors, Ford, and Chrysler), Romney adopted a differentiated strategy. His focus shifted towards producing cars smaller than the prevailing "standard" models in the American marketplace, emphasizing efficiency and cost-cutting measures. This approach aimed to carve out a niche for AMC, particularly as its "legacy" large-sized Nash and Hudson models were experiencing dwindling sales in a market dominated by overly large sedans and a few very small economy cars. The new Rambler line was intended by Romney "to split the market wide open with a mid-size model that featured aggressive styling and plenty of power," offering a compelling alternative to consumers.
A crucial component of this new direction was the development of AMC's V8 engine to compete with those offered by the other automakers. This initiative began in 1955 and was headed by AMC's chief engineer, Meade Moore, and supported by David Potter, who was with Kaiser-Frazer. The decision to manufacture an in-house V8 became imperative after AMC's component-sharing relationships with Packard were terminated by Romney, freeing the automaker to pursue in-house powertrain solutions.
Rapid development produced the overhead-valve (OHV) V8 engine revealed in mid-1956. It first appeared in the Nash Ambassador Special and the Hudson Hornet Special. Despite being the smallest American V8 available then, its output surpassed that of Chevrolet's contemporary two-barrel V8 offerings.
For the 1956 model year, the entire Rambler four-door line underwent a significant redesign. Stylists Edmund E. Anderson and Bill Reddig were responsible for its look, which included a distinctive "dramatic reverse-sloped C-pillar" – a design element that became a signature of AMC. They also incorporated the Pinin Farina-designed inboard, grille-mounted headlamps, a styling cue borrowed from the Nash-Healey sports car.
The redesign was carried into the 1957 model year. The 1957 Rambler Rebel was positioned as a special, high-performance model within the Rambler line. The Rebel showcased AMC's new V8 engine. It combined the lightweight, wheelbase Rambler four-door hardtop body with AMC's larger, newly introduced V8 engine. This combination created a vehicle that surprised the industry, becoming the first factory-produced intermediate-sized high-performance car, a critical precursor to the muscle car era that would explode in the 1960s. Its introduction in December 1956 as a "veritable supercar" immediately put AMC on the map as a contender in performance, even though the company was primarily known for its economy cars.
First generation
1957
American Motors surprised most observers with the December 1956 introduction of the Rambler Rebel – "a veritable supercar". The new 1957 model debuted as a high-performance vehicle that combined AMC's lightweight wheelbase Rambler four-door hardtop body with AMC's newly introduced V8 engine.Note: The AMC engine was introduced five years before the Chevrolet Small-Block V8 of the same size. The General Motors engine of the same displacement never powered AMC automobiles. This made it the first-time that a large block V8 was installed in a mid-size car in the post-World War II marketplace. General Motors, Ford, and Chrysler offered no intermediate-sized cars whatsoever.
Although AMC was best known for their reliable economy cars, this special model came with a bigger engine than anything found at Chevrolet, Ford, or Plymouth—the Rambler's most popular competitors at that time. The Rebel's US$2,786 MSRP base price ($ in dollars ) was economical for the amount of power provided. It was the fastest stock American sedan, according to Motor Trend.
All Rebels came with a manual (with overdrive unit) or GM's four-speed Hydra-Matic automatic transmission, as well as other performance enhancements such as a dual exhaust system, heavy-duty suspension with Gabriel (brand) shock absorbers, and front sway bar. The Rebel was capable of 0 to 60 mph (0-97 km/h) acceleration in 7.5 seconds with its standard carbureted engine. The car's light monocoque (unibody) construction afforded a power-to-weight ratio of about 13 pounds per horsepower, a better ratio than other 1957 model year automobiles and a contrast to Volkswagen's 45.
The Rebel's engine also differed from the 327s installed in the 1957 Ambassador and Hudson Hornet models because it used mechanical valve lifters and a higher compression ratio. Since both engines were rated at 255 hp, it is probable that the Rebel's was underrated.
Power steering and power drum brakes were also standard, as on all Rambler Custom models. The car was available only in silver metallic paint accented with gold anodized aluminum inserts along the sides. Padded dashboards and visors, rear child-proof door locks, and seat belts were all optional. A total of 1,500 Rebels were produced in 1957. Integrated air conditioning system, the All Weather Eye was a $345 option.
The Rebel is considered to be a precursor of the muscle cars (rear-wheel drive mid-size cars with powerful V8 engines and special trims) that became so popular in the 1960s. It also foretold that muscle-type performance would be included among AMC's models.
Fuel injection option The Bendix Electrojector electronic manifold injection (EFI) was to be optional on the 1957 Rambler Rebel with a flashy introduction at the Daytona Beach Road Course trials. The Rebel's Electrojector equipped engine was rated at . This was to have been the first mass-produced engine with a transistorized "brain box" fuel injection system. A Rambler Rebel with the optional EFI was tested by Motor Trend, and they recorded this sedan going faster from a standing start than the 1957 Chevrolet Corvette with mechanical fuel injection.
The Bendix system's public debut in December 1956 was followed by a March 1957 price bulletin listing it as a US$395 option, but because of supplier difficulties, EFI Rebels would only be available after June 15. This was to have been the first production EFI engine, but Electrojector's teething problems meant only pre-production cars were so equipped: thus, very few cars so equipped were ever sold, and none were made available to the public. The Rambler's EFI was more advanced than the mechanical types then appearing on the market and the engines ran fine in warm weather, but encountered difficulty with starting in cooler temperatures. As a result, all of the production Rebels used a four-barrel carburetor. Nevertheless, the EFI option remained in the published owner's manual.
Second generation
1958 For the 1958 model year, the Rebel name returned, but no longer with the 327 engine. Rather than identifying a specialty model, the name was applied to all Ramblers powered by AMC's V8 engine. Rebel came with a four-barrel carburetor and dual exhausts rated at with of torque. The 327 engine was made standard in the more luxurious Rambler Ambassador models. The 1958 Rebel lineup encompassed six models: Super or Custom trimmed four-door sedans and Cross Country station wagons, plus a base Deluxe four-door sedan that was reserved for fleet sales. A four-door hardtop in the top-line Custom trim was now Rebel's sole pillarless model.
These Rebels were no longer the muscle car of 1957, but did offer more power than regular Rambler models. A test by Motor Trend concluded "the V8 powered Rebel is now able to reach a true 60-mph from a standstill in an estimated 12.0 seconds"—significantly slower than the limited-production 1957 Rebel, and this was pretty good for that era.
The 1958 Rambler Rebel and Rambler Six shared revised styling with a new grille, front fenders containing quad headlamps, as well as a new hood design while the rear received new fenders with impressive tailfins. A chrome accent spear began on the front end with another that ran down the body side. The Station wagons were a popular body style.
1959 The 1959 model year Rambler Rebels featured hoods without ornaments, a new full-width grille with large inset turn signal lamps, bumpers, and bumper guards that reduced the overall length by , a thinner roof panel look with narrower C-pillars, windshield and rear window slanted at a greater angle reducing wind resistance, simpler bodyside trim, and restyled rear doors and fenders with a smooth line to the smaller tailfins. Car Life magazine called the 1959 Rambler "one of the most attractive cars on the road".
All Rambler Rebels benefitted from bigger brakes, improved automatic transmission controls, and numerically lower axle ratios for improved fuel economy. A new option was adjustable headrests. The 1959 Rebel came with a four-barrel carburetor and dual exhausts rated at with of torque.
Third generation
1960 American Motors downplayed the Rambler Rebel name in 1960. Rather than focus on the separate Six and Rebel models, as in previous years, the emphasis was placed on the Rambler name and the trim levels, with the notation that each series was offered with "Economy 6" or "Rebel V8" engines. The 1960 model year saw the Rebel available with a lower compression 2-barrel version rated at .
The Rambler Rebel was all new, but retained the same styling concept. The front end featured a full-width die-cast grille, while the two-piece front and rear bumpers were promoted to cut repair costs. The C-pillars were made narrower and the tail fins were now smaller.
Station wagons with two rows of seats came with a conventional tailgate (roll-down rear window and drop-down gate) while three-row models received a new side-hinged door. All station wagons included a standard roof rack. A big feature was the of space, compared for example to the much larger-sized Oldsmobile station wagons that offered only of cargo room. Among the 17 different station wagons that were marketed by AMC for 1960, the Rambler Six Cross Country Super was the most popular.
