Ferrari 275 GTB Competizione Speciale (1964 to 1966)

The first racing version of the 275 was the 275 GTB Competizione Speciale (or 275 GTB/C Speciale). Designed under the supervision of Mauro Forghieri, this model was intended to succeed the 250 GTO as Ferrari's GT-class entry during the 1965 racing season. Ferrari constructed four cars of this type, three of which were manufactured between late 1964 and early 1965, while the fourth was completed in 1966. These cars were equipped with Tipo 213 engines tuned to 250 LM specification, producing approximately 290-305 bhp (227 kW). The extra-thin-gauge alloy bodywork (designed by Pininfarina and built by Scaglietti) was significantly different from the production 275 GTB, with a more streamlined shape similar to the 250 GTO and the 330 LMB. All four cars had slightly differing hand-built bodywork, possibly due to ongoing aerodynamic experimentation by Ferrari engineers.
