In 1960 Pininfarina was asked by Alfa Romeo to design a spider based on the Sprint Speciale. They developed a prototype in 1961, of which ultimately went into production in 1966. The popular Giulia Spider, a mainstay of Alfa Romeo, found its replacement with the Duetto Spider. Reliability and performance were strong, with the majority of the new car's mechanical components carried over unaltered from the proven Giulia.
