The Ferrari 410 Superamerica was first introduced in 1955. The engine, based on a single plug 410 S powerplant, was now up to 5.0 L with 340 PS (250 kW; 335 hp) at 6,000 rpm produced thanks to triple Weber 40DCF carburettors. A 1957 Superamerica series III had triple 46DCF3 Webers for even more power (360 PS (265 kW; 355 hp)) and was also the final development for the 'long-block' Lampredi V12. Each 410 Superamerica had custom bodywork, with a few by Boano and Ghia but most by Ferrari stalwart, Pinin Farina. The price was extremely high—at US$16,800, the 410 Superamerica offered at the New York Auto Show by importer Luigi Chinetti was more than twice as expensive as the Mercedes-Benz 300SL "Gullwing" exhibited by Max Hoffman. Just 35 were built when the series ended in 1959.
