with wire wheels again. Two of the twelve 275 GTB/Cs built were sold for street use. Unlike the race cars, these street cars were fitted with standard 275 GTB-style alloy wheels with Pirelli tyres. After its introduction in 1966, the 275 GTB/C was raced by several independent racing teams with varying degrees of Ferrari factory support, including NART, Maranello Concessionaires, Scuderia Filipinetti, and Ecurie Francorchamps. Three 275 GTB/Cs were entered in the 1966 24 Hours of Le Mans, two of which finished. The Maranello Concessionaires-entered 275 GTB/C (chassis 09035) driven by Roy Pike and Piers Courage finished 8th overall and 1st in class, while the Ecurie Francorchamps 275 GTB/C (chassis 09027) driven by Claude Dubois and Pierre Noblet finished 10th overall and 2nd in class. Other notable victories include a 1st in class at the 1967 Targa Florio, driven by Tullio Sergio Marchesi. Marchesi went on to win the 1966 and 1967 Italian GT Championships driving 275 GTB/C chassis 09007. 275 GTS 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 litre V12, transaxle, chassis and fully independent suspension. Ferrari reported that the engine fitted to the 275 GTS produced . This was less than the reported 280 bhp produced by the 275 GTB, although there was likely no difference in engines between the models. The 275 GTS was never equipped with a torque tube, unlike the 275 GTB series II. This model was fitted with 205Vr15 Pirelli Cinturato CN72 tyres on Borrani wire wheels. The all steel 275 GTS body was designed and manufactured by Pininfarina. Its appearance was entirely different than that of the 275 GTB coupé, with a shorter front hood, smaller uncovered headlights, and overall balanced proportions suggesting earlier 250 Pininfarina Cabriolet models. All 275 GTS were equipped with a folding cloth convertible top and an additional removable hard top was a factory option. Ferrari produced a total of 200 275 GTS between late 1964 and early 1966, including 19 in right hand drive. The 275 GTS was replaced in 1966 by the 330 GTS, leaving no 3.3 L spider in the range until the creation of the 275 GTB/4 NART Spider. Four-cam models The 275 GTB/4 and GTS/4 NART spyder models made up the final production run of the
