Designed for export to North America, the 1957 250 GT California Spyder was Scaglietti's interpretation of an open-top 250 GT. Aluminium was used for the hood, doors, and trunk lid, with steel elsewhere for most models. Several aluminium-bodied racing versions were also built. The engine was the same as in the 250 Tour de France racing car with up to 240 PS (177 kW; 237 hp). All used the long 2,600 mm (102.4 in) chassis, and Pirelli Cinturato 185VR16 tyres (CA67) were standard.
