The Ferrari 275 was a series of 2-seater GT cars, produced between 1964 and 1968, that used a 3.3-L V12 engine instead of the 4.0-L used by the
330 series. The 275 series was the first to change its design when both lines replaced the
250 series. The first two models were a coupe, the 275 GTB and a convertible, the 275 GTS. But in 1966, both models were given a 4.0-L engine and became
330 series models while the 275 line was used to introduce the dual over-head camshaft (DOHC) models called the 275 GTB/4 and 275 GTB/4 Spider. All models were discontinued in 1968 and replaced by the
Ferrari Daytona (365 GTB/4).
