At the 1966 Paris Auto Salon Ferrari launched the GTB/4 with the new four-cam Tipo 226 engine.
It was an important evolution of this sports car that already had 4-wheel independent suspension, disc brakes and a 3.3-liter V12, the final development of the Colombo-designed “short-block” engine. Six Webber carburetors aided in delivering around 300 horsepower.
The Ferrari 275 GTB/4’s stupendous body was designed by Pininfarina and built by Scaglietti.
It was identical in appearance to the long-nose Ferrari 275 GTB but it was easily distinguished by its bulge in the hood. The GTB/4 benefited from a variety of upgrades introduced into the series that were tried and tested in the 275 competition models.
The 4 in the name GTB/4 represented the twin camshafts per cylinder bank totaling four. This was the first quad-cam road-going Ferrari ever created.
During its production run lasting until 1968, just 320 examples were built.
