1976 Ferrari 308 GTB 'Vetroresina' by Scaglietti
Ferrari’s 308 GTB ‘Vetroresina’ is a car that ignites the senses and stirs the soul of anyone passionate about automotive design. This model, produced between 1975 and 1977, stands as a testament to Ferrari’s willingness to innovate, experiment, and push boundaries, all while delivering the kind of style and performance that made the marque legendary. The ‘Vetroresina’-Italian for fiberglass-was the first Ferrari production car to feature a body made entirely from glass-reinforced plastic, a bold move that set it apart from anything else on the road at the time.
The 308 GTB was introduced at the 1975 Paris Salon, replacing the beloved Dino 246 GT and GTS. Ferrari was keen to continue its tradition of mid-engined, two-seater sports cars, but with a new twist: a V8 engine, designed for both performance and reliability. The car’s body was penned by Leonardo Fioravanti at Pininfarina, the same mind behind icons like the Daytona and Berlinetta Boxer. The result was a wedge-shaped silhouette-muscular, purposeful, and quintessentially Italian-that captured the spirit of the 1970s and set the template for Ferrari’s future V8 sports cars.

But what truly sets the ‘Vetroresina’ apart is its construction. Scaglietti, Ferrari’s trusted coachbuilder, was tasked with producing the fiberglass body panels, a process that was both labor-intensive and highly innovative for the era. The use of fiberglass brought the car’s weight down to just 1,100 kg, making it roughly 150 kg lighter than the steel-bodied models that would follow. This reduction in mass translated directly into sharper handling, quicker acceleration, and a driving experience that felt alive and responsive-attributes that make the ‘Vetroresina’ the most sought-after of all 308s among collectors and enthusiasts today.
Underneath the sculpted bodywork sits a 2,926 cc, transversely mounted, dry-sump V8 engine, breathing through four twin-choke Weber carburetors. In European specification, this powerplant delivers a robust 255 bhp at 7,700 rpm, sending the car from 0 to 100 km/h in just over six seconds and on to a top speed of 252 km/h. The five-speed manual gearbox, with Ferrari’s signature gated shifter, is a tactile delight-each shift is a reminder of the mechanical purity that defines classic Ferraris.

The chassis, derived from the Dino 308 GT4 but with a shorter wheelbase, features independent suspension all around, vented disc brakes, and unassisted rack-and-pinion steering. The result is a car that feels agile and communicative, with a balance and poise that rewards spirited driving. The lightweight construction means the ‘Vetroresina’ dances through corners with an eagerness that later, heavier steel-bodied 308s simply can’t match.
Inside, the 308 GTB ‘Vetroresina’ offers a blend of luxury and purpose. Connolly leather seats, a simple yet elegant dashboard, and the iconic gated shifter create an environment that is both inviting and focused. Options like air conditioning were available, catering to buyers who wanted comfort alongside performance. The induction note from the V8, especially with the window down, is intoxicating-a mechanical symphony that connects driver and machine in a way few modern cars can replicate.

Production numbers for the ‘Vetroresina’ are the subject of some debate, but the consensus is that between 712 and 808 examples were built before Ferrari transitioned to steel bodies in mid-1977. This limited production run, combined with the car’s unique construction and dynamic qualities, has made the ‘Vetroresina’ a blue-chip collectible. For those in the know, it represents the purest expression of the 308 formula-a car built for driving pleasure above all else.
Public reception at the time was positive, though some traditionalists were initially skeptical of the use of fiberglass. Over time, however, the advantages became clear, especially to those who valued performance and agility. Today, the ‘Vetroresina’ is celebrated not just for its rarity, but for its role in Ferrari history as a bridge between the past and future-a car that dared to be different and, in doing so, became a legend in its own right.

The Ferrari 308 GTB ‘Vetroresina’ by Scaglietti is more than just a beautiful object; it’s a milestone in automotive design and engineering. Its lightweight construction, striking design, and thrilling performance make it a car that continues to inspire passion and admiration. For anyone who loves the art and science of car making, the ‘Vetroresina’ is a reminder of what happens when bold ideas meet uncompromising execution-a true masterpiece from Maranello’s golden era.
