Alfa Romeo Giulietta Sprint Speciale prototype Bertone

Which Sprint Speciale prototype is this?

This profile concerns the first Giulietta Sprint Speciale prototype, identified by the Lopresto Collection as chassis AR10120-00001. Its 1957 Turin presentation is the documented public milestone. The inventory’s 1956 reference is retained only in the catalogue audit metadata; it is not used as the car’s verified presentation year. This precise identity keeps the profile focused on a specific historical object. Read the cited reference for its documented context.

Scaglione’s aerodynamic direction

The collection credits Franco Scaglione at Bertone and connects the design with the earlier B.A.T. studies. That relationship gives the prototype a useful position between experimental show-car thinking and a production sports coupe. Its collector significance comes from the design stage it represents, not simply from being an unusually attractive example of the later Sprint Speciale.

Documented mechanical details

The owner’s collection record identifies a 1290 cc inline-four and a 2250 mm wheelbase. It also records engine number AR00120-00003. These are specific to the collection’s prototype entry. Production Sprint Speciale figures for weight, gearbox, brakes and output should not be copied across automatically when the prototype record does not establish the same configuration.

Prototype and production car

The collection dates production introduction to 1959 and explains that the production form used less extreme proportions. This makes the prototype a design precursor, rather than the first example of an unchanged production run. Comparing the two is useful, but the comparison needs the right photographs and dated specifications; a later low-nose production SS still has a different identity.

A one-car scope

The count of one applies to this identified first prototype. It does not claim that only one development car was ever involved in the Sprint Speciale programme. Nor should the production SS total be used to describe the rarity of chassis 00001. For an archive of special cars, identifying the scope of the count is as important as entering the number.

A documented return to public display

The collection records the prototype’s appearance at the 2017 Villa d’Este concours, sixty years after the Turin debut. That later presentation belongs in the car’s ownership and restoration chronology. It does not turn a modern concours photograph into a period image. The car’s long history is best understood by retaining the distinction between original presentation, subsequent condition and later public return.

Preserving a prototype’s identity

A prototype record needs more than a model name and an attractive photograph. Establish the chassis, the coachbuilder’s records and the dated sequence of show appearances. Record changes to paint, glazing, interior and mechanical equipment when evidence permits. A later alteration can be an important part of a show car’s working life. Keeping those stages separate allows the archive to explain the object as it developed rather than inventing a single specification that supposedly remained unchanged from its first presentation.

Restoration evidence and interpretation

For a unique design study, conservation and reconstruction are central to its historical account. Keep photographs of the earliest known form alongside records of later repairs and the reasoning behind restored details. Identify what was retained, repaired or recreated wherever the evidence is available. Museum display and concours presentation can provide useful context, but neither alone documents every component. A photograph illustrates one moment in the car’s life; its caption should identify that moment, leaving detailed material authenticity to the accompanying chassis and restoration record.

Frequently asked questions

What is the documented presentation year?

1957, at the Turin Motor Show.

Which chassis is profiled?

AR10120-00001, as identified by its owning collection.

Is it the 1965 Giulia SS prototype?

No. That is a different, larger-engined design study.

Does one mean all SS prototypes?

No. It refers to this specific first prototype.
