When the Ferrari 275 GTB was presented in 1964, few people imagined a sporting future for this berlinetta with generous dimensions and a very long nose. In fact, already in 1965 some competition units were set up, called 275 GTC. At the 1966 Paris Motor Show, Ferrari presented an enhanced version, equipped with a new 12-cylinder 4-cylinder overhead camshaft, from which the 275 GTB4 was derived. Aesthetically, the new car did not differ from the GTB except for a bulge on the hood, to allow the housing of the six carburetors, for a slightly different nose and for the more enveloping front bumpers.
