Introduced at the Paris Motor Show in October 1966, the 275 GTB/4 (or 4-cam) was a substantially updated car; built by Scaglietti, it featured new bodywork and was the first Ferrari to not be offered with wire wheels.

Power came from a substantially reworked Colombo V12, still with two valves per cylinder but now with a four-cam engine and six carburettors as standard. In a departure from previous Ferrari designs, the valve angle was reduced three degrees to 54° for a more-compact head. The dual camshafts also allowed the valves to be aligned "correctly" (perpendicular to the camshaft) instead of offset as in the SOHC Ferraris. It was a dry-sump design with a huge 17 qt (16 L) capacity. The individual cylinder capacity remained unchanged at slightly under 275cc, which as before gave the model the first three digits of its name, and when multiplied by the number of cylinders equals 3,286cc total swept volume.

The transaxle was also redesigned. A torque tube connected the engine and transmission, rather than allowing them to float free on the body as before. This improved handling, noise, and vibration. Porsche synchronizers were also fitted for improved shifting and reliability.

The 275 GTB/4 could hit 165 mph (266 km/h) with its 300 hp (220 kW). 280 4-cam versions were produced through 1968.

In 2004, Sports Car International named the 275 GTB/4 number seven on the list of Top Sports Cars of the 1960s.

 The Ferrari 275 was a two-seat front-engined Gran Turismo automobile produced by Ferrari between 1964 and 1968. It used a 3.3 L (3286 cc) Colombo 60° V12 engine and produced 280-300 hp. The Pininfarina-designed body was a graceful evolution of the car's predecessor, the 250, and strongly contrasted with its replacement, the Daytona. The 275 introduced Ferrari to the "transaxle", where the transmission and rear axle are integrated.

Ferrari 275 GTB/4 NART

A 275 GTB/4 N.A.R.T. Spyder version was only available from a single American dealer, Luigi Chinetti. He asked Sergio Scaglietti and Enzo Ferrari to build a few Spyder, a convertible with no roof, versions of the 275 GTB/4, which he bought for approximately $8,000 each; N.A.R.T. stood for Chinetti's North American Racing Team. It was to be a custom run of 25 cars straight from Scaglietti, but just 10 were built in 1967 and 1968, making this one of the most valuable Ferraris. The ten NART Spiders used chassis numbers 09437, 09751, 10139, 10219, 10249, 10453, 10691, 10709, 10749, and 11057.

In August 2013, a 1967 275GTB/4 (chassis #10709), owned by the late Eddie Smith of Lexington, North Carolina, sold for US$27.5 million at auction in California. This was a one owner car that, while was not driven daily, was driven on a regular basis. It had remained in the Smith Family for 45 years.

The NART driven by Faye Dunaway in the 1968 film The Thomas Crown Affair, was serial number 09437, the first produced. It came second in its class in the 1967 12 Hours of Sebring before being repainted and used for the movie. In August 2005, it fetched $3.96 million at auction.
