 The Ferrari 250 Sport , was a racing sports car, which was developed in 1952 at Scuderia Ferrari .

History

The 250S was truly one-of-a-kind. Vignale designed and built the Berlinetta body and tubular steel chassis. The automobile started out as a 225S with chassis number 0156ET, but it was rebuilt. The conversion work was mostly focused on the engine, and it was one of Aurelio Lampredi's first projects for Enzo Ferrari. Lampredi expanded the size of the cylinder to 73 mm while keeping the stroke at 58.8 mm. Three Weber twin type 36DCF gasifiers were used to prepare the mixture. The front suspension consisted of a double wishbone and transverse leaf springs, while the rear suspension consisted of a solid axle.

The 250S appears in numerous denominations in various Ferrari publications and race result lists, as it does so frequently with Ferrari typology. The labels 250S, 250 Sport, 250S Coupe Vignale, and 250S Berlinetta Vignale all relate to the same model because it was a one-off. The type designation harkens back to Ferrari's old practise of naming models based on the displacement of a single cylinder. The V-12 engine built by Gioacchino Colombo has a total capacity of 2953 cc.
