Italian concept cars of the late 1960s and 1970s used radical shapes, cabins, glazing and aerodynamic devices to challenge what a car could look like and how people could use it. This curated selection spans Bertone, Pininfarina and Italdesign studies, from the Carabo’s wedge to the Marzal’s glass doors and the Boomerang’s steering-wheel instruments; some also helped inform production cars.
These cars are design milestones, not an objective ranking. Their boundary-pushing ideas ranged from experimental proportions and interfaces to concepts that could be translated into a road-going model.
10 Italian concept cars that pushed design boundaries
1. Lamborghini Marzal (1967)
Designed by Marcello Gandini at Bertone, the Marzal explored Ferruccio Lamborghini’s interest in a four-seat grand tourer related to the Miura. Its crystal-glass gullwing doors and silver-trimmed seats made the cabin a defining part of the exterior design. Lamborghini says the car was presented at the 1967 Geneva Motor Show.
The production Espada drew directly from the Marzal, though its doors and extensive glazing were adapted for a production car. The Marzal is a clear example of a dramatic show-car idea becoming a more usable grand tourer.

2. Alfa Romeo Carabo (1968)
Marcello Gandini designed the Carabo for Bertone using Alfa Romeo Tipo 33 mechanicals. Its low wedge, intersecting geometric forms, vivid contrasting colors and vertically opening doors broke decisively with the rounded sports-car shapes familiar at the time. Alfa Romeo’s museum records a rear-central 2.0-liter V8 rated at 230 hp, a 700-kg body, fiberglass construction and one example.
The Carabo’s importance is chiefly architectural: it established a visual vocabulary later associated with Gandini’s Lamborghini Countach. Its striking door mechanism was part of the concept’s design statement, not evidence that every later wedge car copied it.

3. Autobianchi A112 Runabout (1969)
Presented by Nuccio Bertone at the 1969 Turin Motor Show, the open barchetta was shaped by Marcello Gandini. Bertone describes its sharp horizontal beltline and L-shaped upper contour as drawing inspiration from Italian motorboats.
The Runabout paired an exotic, open-cockpit look with a compact mid-engine sports-car idea. It helped point toward the Fiat X1/9, showing how an experimental design proposition could inform a more practical car.
4. Pininfarina Ferrari P6 (1968)
The Ferrari P6 offers a quieter counterpoint to the era’s dramatic wedges. Pininfarina used the concept to explore a measured mid-engine sports-car profile, including cockpit placement, surface treatment and the relationship between aerodynamic clarity and Ferrari identity.
It is best understood as a transitional design study, not as the single direct origin of a later Ferrari model. Its significance is that Italian concept work also advanced through disciplined experimentation, not only visual shock.
5. Ferrari 512 S Modulo (1970)
Designed by Paolo Martin for Pininfarina, the Modulo reduced a sports prototype to a very low, nearly monolithic volume. Its canopy-like cockpit, perforated bodywork and partially enclosed wheels suppress familiar hood and fender cues, making the car read as one aerodynamic sculpture.
The Modulo is best treated as a visual and aerodynamic thought experiment rather than a practical production proposal. Its design belongs to the handmade, sculptural prototype culture of the period; Ferrari’s account of that modeling tradition provides useful context.

6. Lancia Stratos Zero (1970)
Marcello Gandini’s Stratos Zero for Bertone challenged ordinary assumptions about car height, seating and entry. Stellantis describes it as a fully functional concept, only 85 centimeters high, with near-horizontal seats, unusual lighting and a windshield that lifted for entry.
The car’s striking proportions were paired with running gear, and its visual and conceptual ideas became a precursor to the Lancia Stratos road and rally car. The transition was not a literal transfer of the Zero’s form, but a radical proposal distilled into a usable vehicle.

7. Maserati Boomerang (1972)
Giorgetto Giugiaro developed the Boomerang at Italdesign over Maserati Bora chassis. First shown as an epowood model, it became a running one-off. Its wedge body uses largely straight lines, while the circular instrument display integrated into the steering wheel makes the cockpit part of the same geometric experiment.
Italdesign lists a 310-hp V8, a top speed near 300 km/h and a windshield rake of 13 degrees. The divided steering column was conceived with frontal-impact safety in mind. Together, these details made the Boomerang’s abstraction an organizing principle for both exterior and interior design.

8. Alfa Romeo Caimano (1971)
Italdesign built the Caimano using Alfa Romeo Alfasud mechanics and platform, but described it as a dream car with no production possibility. Its cabin is organized around a hinged dome incorporating the roof, doors and front hood. Small side windows served practical purposes such as toll payment and low-speed ventilation.
A multi-position rear roll-bar/spoiler and cylindrical instrument display extended the experiment to aerodynamics and driver information. The Caimano treated the cabin as a movable capsule rather than a conventional passenger compartment.

9. Lamborghini Bravo (1974)
The Bertone Lamborghini Bravo shows how the wedge language had developed into a more compact, production-oriented supercar proposal. It serves as a design-development bridge between earlier Bertone experiments and the visual culture of the Countach era.
Available documentation for the Bravo is thinner than for several other cars in this selection, so it is better to describe its design role than to attach precise performance claims or assert a specific production influence.
10. Alfa Romeo Navajo (1976)
Bertone’s Navajo continued the 33-based concept-car lineage that included the Carabo. Its fiberglass body, lengthened tubular chassis, tapered front and horizontally disappearing headlamps gave the car an unmistakably futuristic form.
Its aerodynamic ideas were visible rather than hidden: the design included an automatically regulating front spoiler and adjustable rear aerodynamic elements. The Navajo made airflow and downforce central subjects of the car’s appearance.

Across the selection, the wedge became a new visual grammar for expressing speed and a break from rounded coachwork. The Marzal and Modulo used glazing to change how the cabin and body were perceived, while the Boomerang, Caimano and Stratos Zero experimented with instruments, entry and seating. The Navajo made aerodynamic devices part of the visual message.
Concepts also differed in how directly their ideas could reach production. Lamborghini identifies the Marzal as a source for the Espada; Bertone connects the Runabout’s compact mid-engine proposition to the Fiat X1/9; and the Stratos Zero became a visual and conceptual precursor to the Lancia Stratos. Other cars in this selection are more useful as design studies or transitional experiments than as direct production blueprints.

Bertone, Pininfarina and Italdesign operated as design laboratories alongside manufacturers, giving companies a way to explore ideas beyond a conventional product cycle. That does not mean every later wedge-shaped car copied a particular prototype; it means these concepts helped establish and test a broader design vocabulary.
FAQ
What is the difference between a concept car and a production car?
A concept car is a design or engineering study presented to explore ideas. It may be a static model, a running prototype or a one-off vehicle, and it is not necessarily intended for sale. Some ideas may later be adapted for production.
Which Italian concept cars directly influenced production models?
The dossier identifies the Marzal as a direct influence on the Lamborghini Espada, the Autobianchi A112 Runabout as pointing toward the Fiat X1/9, and the Stratos Zero as a visual and conceptual precursor to the Lancia Stratos. These relationships do not mean the production cars were identical to the concepts.
Why is the Lamborghini Marzal notable?
The Marzal explored a four-seat grand tourer and made its crystal-glass gullwing doors and highly transparent cabin central to the design. Lamborghini says the Espada subsequently drew directly from it, with the most extreme details moderated for production.

What made the Maserati Boomerang’s cockpit unusual?
The Boomerang integrated a circular instrument display into the steering wheel. Italdesign also describes a divided steering column conceived with frontal-impact safety in mind, making the cockpit an important part of the concept’s design experiment.
