1969 Alfa Romeo 33 Iguana Concept
By Lorenzo Bianchi October 22, 1969
The 1969 Alfa Romeo 33 Iguana Concept debuted at the Turin Motor Show in November 1969, designed by Giorgetto Giugiaro using the mechanical foundations of the Alfa Romeo 33 Stradale.
Its distinctive exterior features a sharply pointed front, minimalist Alfa Romeo shield, steeply raked windshield, bright metallic bodywork and adjustable rear spoiler.
The one-off concept features Campagnolo alloy wheels with elliptical openings and a simplified interior. It belongs to the Stellantis Heritage collection and is housed at the Alfa Romeo Historical Museum in Arese.
The Alfa Romeo 33 Iguana Returns to the Spotlight
The 1969 Alfa Romeo 33 Iguana Concept remains one of Giorgetto Giugiaro's early interpretations of the Italian sports car. Introduced at the Turin Motor Show in November 1969, the one-off was developed on the mechanical foundations of the Alfa Romeo 33 Stradale.
Its design returned to public attention at Milano AutoClassica in November 2024, where Stellantis Heritage displayed the Iguana alongside other historic Alfa Romeo models. The exhibition was a heritage appearance, not a new vehicle launch.
Sharp Front End and Low Wedge Profile
The Iguana moves away from conventional rounded sports-car surfaces. Its front end is sharply tapered, with taut body lines and a narrow, minimalist interpretation of Alfa Romeo's shield.
A broad, steeply inclined windshield meets a low roof, giving the car a stretched silhouette. The profile is especially striking in the official heritage photograph, where the metallic bodywork catches light along the flat flanks and angular rear quarters.
The effect is notably different from the 33 Stradale on which its mechanical layout was based. Stellantis describes the shape as an early indication of the design direction that would become prominent during the 1970s.
Rear Spoiler and Campagnolo Alloy Wheels
Behind the passenger compartment, an adjustable rear spoiler is integrated into the concept's tail. It introduces a functional-looking detail without disrupting the wedge profile.
Campagnolo alloy wheels provide a recognisable link with the 33 Stradale. Their elliptical openings contrast with the body's long, straight surfaces, bringing a distinctive technical detail to an otherwise restrained side view.
The source does not identify the wheels' dimensions, tyre sizes or aerodynamic performance of the spoiler.
Simple Cabin Behind the Slanted Windshield
Giugiaro gave the Iguana a simple, linear interior rather than repeating the more elaborate exterior geometry throughout the cabin.
Stellantis offers no further specifications for its instrumentation, upholstery or passenger accommodation in the supplied historical description.
What is apparent from the design brief is the emphasis on clarity: the strongly defined exterior and relatively understated cabin served different purposes within the same experimental coupe.
A 33 Stradale Mechanical Foundation
The concept used the mechanical base of the Alfa Romeo 33 Stradale, the sports car introduced in 1967.
That connection places the Iguana within Alfa Romeo's performance-car history, although the heritage release does not confirm its specific engine output, gearbox configuration, acceleration or top speed.
Figures belonging to other 33 Stradale variants should therefore not be treated as verified Iguana specifications.
Preserved at the Alfa Romeo Museum in Arese
The sole Iguana belongs to the Stellantis Heritage collection and is normally housed at the Alfa Romeo Historical Museum in Arese.
For the November 15–17, 2024 Milano AutoClassica exhibition, it appeared with the 1750 Spider Veloce and 4C Superbike. The contemporary 33 Stradale and Junior were also presented, illustrating different periods of the marque's design.
Stellantis used the event to highlight Officine Classiche's preservation and restoration work. The Iguana's appearance offered a rare public look at a 1969 concept whose proportions and detailing anticipated a changing era of Italian automotive design.
