Dual-Ghia is a rare, short-lived, automobile make, produced in the United States between 1956 and 1958. The idea for a sporty limited production car came from Eugene Casaroll, who controlled specialized vehicle builder Dual-Motors Corporation based in Detroit, Michigan; the name Dual-Ghia is representative of the collaborative efforts between the two builders.
The design for a luxurious sports car was to be a modified version of the Ghia-built 1954 and 1955 Dodge-based concept cars known as the Firearrow I, II, III, IV and the nearly production-ready Firebomb; which had all been designed by Luigi Segre with some possible influence from Virgil Exner. With so many cars designed along the same theme, Chrysler may well have intended to produce the Firebomb and/or the Chrysler Falcon as a response to the Ford Thunderbird and Chevrolet Corvette; for whatever reason neither made it to production. After gaining rights to the Firearrow/Firebomb design, Casaroll asked Ghia's U.S. representative (and eventual Dual-Motors VP) Paul Farago to further develop the Firebomb into a production-friendly vehicle. The series-produced design utilized an even greater number of standard production MoPar fittings, the (road-legal) Firebomb two headlamp configuration, incorporated modest tail fins and was somewhat more slab-sided and square-edged in comparison to the Firearrow/Firebomb series. While a four-place convertible was the only official body type at least one coupe was built.
The "world's longest assembly line" involved transporting a Dodge frame and drive-train to Italy, where the bodywork and interior was fabricated by the coachbuilders at Ghia; once the partially completed vehicles were back in the U.S. Dual-Motors handled the rest. Performance was excellent, due to the cars being powered by the 315 cu in (5.2 L) Dodge hemispherical-head short-stroke V-8 engine. Not all were built with the 315 cuin Dodge hemisperical head engine. Some 1957's were built with the Dodge D-500 361 cuin dual quad carburetor.
