The Gran Sport was inspired by an article published by Italian car magazine Quattroruote, and was built in collaboration with Milanese coachbuilder Zagato.

The first prototype was introduced in April 1965 at a coachbuilders' motor show at the Museo Nazionale dell'Automobile in Turin, while the first production version was unveiled a year later, at the New York Auto Show.

Alfa Romeo supplied a purpose-built bare chassis to Zagato, where the bodies were hand-built and the cars finished.
Engine, gearbox and other mechanicals were from the 105-series Giulia TI.
The vehicles were sold through Alfa Romeo's dealer network.
 Alfa Romeo produced 12 chassis in 1965, 52 in 1966, and 29 in 1967.
