The Ferrari 275 history followed on from the 250, with a few significant differences. It was built from 1964 until 1968 in various versions, as detailed below.
Aside from the specially built ‘P’ race cars, all the vehicles adopted the identical fundamental design with a longitudinal V12 at the head, driving the rear wheels through the rear-mounted combined transmission and differential.

Independent suspension type was double wishbones and all-round coil springs, and 4-disc brakes to stop the vehicle.
As a substitute for the highly successful 250 GT, 275 GTB was released in 1964 in Paris. The car has provided many design cues from its predecessor, and mechanically it is a significant advance.
The body design was done by Pininfarina and was inspired by the 250 classic GTO and other 250 model family members.
The most significant change is in the independent rear suspension (this first happened to Ferrari road cars).
The transmission uses double wishbones in which the rear transaxle houses the complete trans (five-speed gearbox) and the final drive.
These two significant changes make the car’s chassis much more reliable in Ferrari 275 history.
The overall effect is supported by a new 3,126 ccs (77×58.8mm) V12 engine, which produces 280 bhp of power with the support of three twin carburetors.
The clutch is still attached to the engine’s rear, and from there, the sturdy prop shaft extended.
Later this part was replaced by a more robust torque tube. The braking process uses all-around discs. The wheelbase is 2,400 mm with an empty weight of 1,100 kg.
Since 1965 Ferrari has slightly modified the design. The most obvious change is the expansion of the nose. For this reason, later cars were known as ‘long nose’ models.
Modifications are made to reduce the lifting of the front end when the vehicle runs at high speed. Other changes include a revised grille and a more upper bumper. But there are other less apparent differences like a bigger boot, a slightly modified prop shaft, and a revision of fuel tanks.
With the development of the ongoing GTB / 4, Ferrari built the second 275 GTB series in 1966 during the summer. These cars are the same as the series I, but there were six Weber 40 DCN carburetor installations and the use of a new dry-sump system, which were both included in the GTB / 4 features.
Car production continued until it was replaced by 275 GTB / 4 in 1966. Ferrari manufactures around 240 units of original cars, 205 units of the ‘long nose’ version, and 12 units of series II cars.
Along with 275 GTB at Paris Motorshow in 1964, Ferrari launched 275 GTS Spider. Mechanically identical to a coupe, this car shows an entirely different body, again designed by Pininfarina.
To replace the California 250, 275 GTS has a far more sporty image than its coupe sibling, more like the roofless classic GT models. Not less than 200 vehicles were successfully produced in the two years after it was launched in Ferrari 275 history.
The Paris Motorshow in 1966 saw the arrival of the new 275GTB/4, the designation referring to the most meaningful technical development, namely the adoption of twin camshafts per cylinder bank (i.e., 4 in total).
The capacity remained the same while the power went up to 300bhp @ 8,000rpm. As mentioned above, the earlier cars’ three carburetors were replaced by a bank of six Weber 40DCN units. It was the beginning of a Ferrari quad-cam road-going built and easily recognizable by the bulge on the hood compared to previous SOHC cars.
The vehicle’s head, however, posed some reliability problems, and frequent service by qualified mechanics was most needed. Because the Spider 275 GTB unit (275 GTS has an entirely different design), Chinetti, as the NART boss, requested several versions of the Spyder to be built, and the work was carried out by Scaglietti.
Some are made by cutting the roof out of coupé cars, while some are created as Spyders. Once completed, the final result is known as ‘275 GTB Spider Nart’ of the ten chassis. About 320 units of 275 GTB / 4 were built before production stopped in early 1968.
275 P & P2
This racing car was developed to beat Ford at the World Championship, a mid-engine roofed car. In addition to the 3.3-liter unit at 275 P, they also make 4-liter and 4.4-liter versions.
In 1965, three models of 275 new GTB were produced for motorsport. These cars have been designed for endurance races in Ferrari 275 history. They have a very light aluminum body with six carburetors. Dry-sum lubrication is intended to improve the performance aided by the engine with 320 bhp power output. Also, other competition modifications such as air vents for brakes and perspex windows are applied.
