Ford Thunderbird (eighth generation)

The eighth generation of the Ford Thunderbird is a personal luxury coupe that was manufactured and marketed by Ford from the 1980 to 1982 model years. Introduced to commemorate the 25th year of the Thunderbird, the eighth generation was substantially downsized, transitioning further into the mid-size segment. For a second generation, the Thunderbird remained the Ford counterpart of the Mercury Cougar XR7; while the Cougar again served as a complete line of mid-sized cars in various body styles starting with 1981 models, the Thunderbird was offered solely as a two-door personal luxury coupe. While better-handling and more fuel-efficient than its Torino-based predecessor, the eighth-generation Thunderbird was poorly received by critics and buyers, leading to a collapse in sales (combined 1980–1982 production outsold 1979 production by only 4,000 cars). In response, the 1983 ninth-generation Thunderbird received an extensive redesign of the exterior (though sharing nearly identical chassis underpinnings), as Ford sought to remarket the model line. The eighth-generation Thunderbird was assembled by Ford at Atlanta Assembly, Lorain Assembly, and Chicago Assembly; the former two facilities are now closed.

Model background

During the late 1970s, fuel economy became a leading objective of the redesigns of American-brand automobiles; as part of the introduction of CAFE, manufacturers that sold cars in the United States were required to average 20.0 MPG for their passenger cars by the 1980 model year. In response, Ford repackaged the Thunderbird for the 1977 model year. Previously a Ford version of the Continental Mark IV coupe, the 1977 Thunderbird adopted the Ford Torino intermediate-segment chassis. Replacing the relatively obscure Ford Elite, the Thunderbird remained in the personal luxury segment, becoming the Ford counterpart of the Mercury Cougar XR7. Though reduced in size, the downsized Thunderbird saw increased competition, marketed against the Chrysler Cordoba, Dodge Charger, Dodge Magnum and the quartet of GM A-body coupes (Buick Regal, Chevrolet Monte Carlo, Oldsmobile Cutlass Supreme, and Pontiac Grand Prix). In only three years in the marketplace, the model line proved successful, selling over 955,000 examples. However, by the 1979 model year, the Thunderbird had become obsolete in comparison to both its competitors and within the Ford model line. For 1978, General Motors downsized its mid-size A-body line (with exterior dimensions closely matching its "compact" lines); the redesign was well-received, with the Oldsmobile Cutlass becoming the best-selling car in the United States in 1978 and 1979. For 1979, the Ford LTD was downsized; though 8 inches shorter than the Thunderbird, the LTD offered larger interior dimensions. For 1980, Ford moved the Thunderbird to an extended-wheelbase variant of the Ford Fox platform. Moving from the intermediate segment to the mid-size segment, the 1980 Thunderbird closely matched the 1978 GM A-body coupes in its exterior footprint.

Design overview

In contrast to the previous generation (which served as a mid-cycle restyling and rebranding of the Ford Elite), the eighth-generation Thunderbird was the first version of the model line to integrate downsizing as part of its design process. The 1980 Thunderbird shed 17.3 inches in length, 4.4 inches in width, and 5.6 inches of wheelbase from its 1979 predecessor; (dependent on powertrain) the curb weight was reduced by up to 1,400 pounds. Serving as one of the most extensively downsized model ranges of the American automobile industry, from 1976 to 1980, the Thunderbird shed over 25 inches of length, 12 inches of wheelbase, and nearly 1,900 pounds of curb weight. In comparison to the 1958–1960 generation, the 1980 Thunderbird is approximately five inches shorter in length and four inches shorter in wheelbase. Chassis. The eighth-generation Ford Thunderbird is a long-wheelbase variant of the rear-wheel drive Ford Fox platform; stretched to 108.4 inches, it shares its chassis with the Mercury Cougar XR7 (1980–1982), the Lincoln Continental (1982–1987) and the Continental / Lincoln Mark VII (1984–1992). The adoption of the Fox architecture marked the return to unibody construction for the Thunderbird (not used since 1966). Shared with the Fairmont and Mustang, the Thunderbird had MacPherson strut front suspension and a four-link live rear axle with coil springs on all four wheels; both front and rear axles were equipped with stabilizer bars. As an option, the Thunderbird was offered with heavy-duty "handling" suspension, a limited-slip rear-axle, and aluminum wheels equipped with Michelin TRX tires. For the first time, the Thunderbird was equipped with rack and pinion steering. As with the Fairmont/Granada, the Thunderbird was equipped with front disc brakes and rear dr

Motorsport

For its 1981 season, two major changes were adapted by NASCAR for its Winston Cup racing series. Coinciding with downsizing of passenger automobiles, NASCAR reduced the wheelbase of Winston Cup cars from 115 to 110 inches. To ensure chassis consistency, NASCAR abandoned its previous practice of three-year model eligibility, requiring teams to adapt to current-production vehicles. In response to the rule change, Ford debuted the eighth-generation Thunderbird (while also eligible, no drivers fielded a Mercury Cougar XR7). The Thunderbird finished the 1981 season with 7 wins (second only to the 22 wins of the Buick Regal). For 1982, the Thunderbird was less successful, winning only two races.
