The ninth generation of the Ford Thunderbird is a personal luxury coupe that was manufactured and marketed by Ford for the 1983 to 1988 model years. In response to the sales downturn of the 1980–1982 Thunderbird, the Thunderbird underwent an extensive model revision for the 1983 model year. While remaining a personal luxury coupe (to minimize overlap with the Ford Mustang), the redesign of the Thunderbird marked a transition of the model range, emphasizing performance and handling over outright luxury and comfort content. As a central theme of the design, the ninth-generation Thunderbird marks the introduction of highly aerodynamic body design to Ford vehicles in North America.
