Descrição
By 1960, the case was made. The laboratory, i. e., Formula 1, had demonstrated in competition the efficiency of the rear mid-engine in the optimal exploitation of high power. After much hesitation, Enzo Ferrari decided to use it first for his single-seaters and then for his sports prototypes in 1961. For road cars, however, there was no question of it yet, despite the pressure from the competition.
Two new Ferraris made their debut at the 1964 Paris Salon: the 275 GTB and its convertible counterpart the GTS. The chassis were identical, with the now-typical welded steel tubular frame, fully independent suspension with unequal-length A-arms front and rear, disc brakes, and tubular shock absorbers. The engines were also identical 3. 3-liter Colombo V12, though the berlinetta produced 280 hp while the spider was rated at 260. Both models had a five-speed transmission mounted in unit with the rear axle. The clutch and bell housing were at the engine. With the rear-mounted gearbox came independent rear suspension, making the 275 GTB the first street Ferrari to be so equipped.
