There had been open-top Ferrari road cars before the advent of the '250' series, but it was, chiefly, Pininfarina's offerings on the latter chassis that established the convertible as a fixture of the Ferrari range. After the experimentation and variety which characterised the coachwork of the 250-series cars, the arrival of the '275' in 1964 brought with it standard bodywork, that of the 275 GTS being manufactured by Pininfarina themselves. In Ferrari nomenclature of the period a model's designation reflected an individual cylinder's cubic capacity, so the newcomer displaced 3.3 litres, up from its predecessor's 3.0 litres. In standard trim the GTS's Colombo-type, 60-degree, V12 engine produced 260bhp at 7,000rpm, some 20 horsepower fewer than when installed in the contemporary 275 GTB.The chassis followed Ferrari's established practice, being a multi-tubular frame tied together by oval main tubes, and for the first time on a road-going Ferrari there was independent rear suspension, the latter employing a double wishbone and coil-spring arrangement similar to that of the 250 LM sports-racer. The adoption of a rear-mounted five-speed transaxle combining the now all-synchromesh gearbox and differential in a single unit helped improve weight distribution, and this feature would characterise future generations of front-engined Ferrari road cars. Produced between 1964 and 1966, the 275 GTS altered little during the course of its short life apart from the adoption of constant velocity joints for the open prop shaft shortly after the commencement of production.By the mid 1960s Ferrari's road cars were beginning to lose some of their rougher edges and take on a more luxurious mien, and the 275 GTS interior is notable for its generously sized seats and wood veneer dashboard, the latter appearing for the first time in a Ferrari. Even the most sybaritic of customers, though, would acknowledge that the driving experience is the raison d'être of Ferrari ownership and in thi
