📚 Vehicle History

Ferrari Legacy:

The Dino name was used by Ferrari to brand smaller-displacement, more road-oriented sports cars, historically to bypass homologation rules for V12 engines. The 308 GT4 represented a significant evolution with its V8 engine and Pininfarina's original design, later rebadged as a Ferrari. This model marked Ferrari's entry into the practical, mid-engined coupe segment.

Design Change:

Initially designed by Marcello Gandini for Bertone, it featured a radical wedge shape. The production version was subtly revised by Pininfarina to be more in line with Ferrari's styling language, though it remained distinct. It evolved into the 308 GT4 and later the Mondial model range.

Production Years:

1973–1980

Production Numbers:

Approximately 2,826 units produced globally.

Manufacturing Location:

Maranello, Italy

🏆 Awards & Recognition

Automotive Awards:

While specific 'awards' are scarce, the Dino 308 GT4 is recognized by enthusiasts and collectors for its historical significance as Ferrari's first mid-engined V8 and its unique styling, making it a desirable classic car.
