Along with the coupe version, Ferrari also revealed the 308 GTS Quattrovalvole - the 308 GTB Quattrovalvole targa version. The car remained into production from 1982 to 1985, with 3042 units produced, in both right and left hand drive versions. All US market examples were fitted with catalytic convertors.

The Quattrovalvole part of the model name referred to the four valves per cylinder heads on the engine, which provided increased power over the preceding model.

Along with the other chages, also seen in the coupe version: the addition of a slim louvre panel in the front lid to aid radiator exhaust air exit, paired electrically operated door mirrors with a small enamel Ferrari badge on the shell, a revised radiator grille with rectangular driving lights at the extremities, and rectangular (instead of round) side repeater lights, on the targa version the removable grained satin black finished roof panel was stowed in a vinyl cover behind the seats when not in use.
