The 275 GTS was a two-seat grand touring spider produced from 1964 to 1966. The 275 GTS was introduced at the same time as the 275 GTB and was mechanically almost identical, sharing the 3.3 liter V12, transaxle, chassis and fully independent suspension. Ferrari reported that the engine fitted to the 275 GTS produced 260 bhp (190 kW). This was less than the reported 280 bhp produced by the 275 GTB, although there was likely no difference in engines between the models.
