Why it matters

The C52 "Disco Volante" (flying saucer) is regarded as one of Alfa Romeo's most fantastical models. It was a publicity car for the 1900 range, built while the company was cutting back racing and shifting to mass production, and it reused the 1900 mechanical underpinnings under a radical low-drag aluminium body.

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

The C52 was introduced at the 1952 New York International Motor Sports Show and developed with Carrozzeria Touring, which supplied its Superleggera tubular construction and an aluminium body. RM Sotheby's says only three 1.9-litre examples were built; one was reworked to counter lift from the swollen fenders and became the "Fianchi Stretti" (narrow-hipped) car, chassis AR.1359.00002, now in the Schlumpf collection in France.

The museum lists five cars under the Disco Volante heading: one spider, one coupé, one "Fianchi Spessi" and two spiders on the 6C 3000 engine.

Identification guide

How to tell an original from a replica or later conversion.

The original narrow-hipped car is chassis AR.1359.00002, held in the Schlumpf collection at the French National Automobile Museum. RM Sotheby's describes it as the sole surviving example of that model and notes it carries later changes, such as turn indicators and a full aluminium dashboard, not present when Alfa Romeo owned it in October 1954. Recreations exist, for example the fifth car built in 2019 by OHA Automobili of Buenos Aires, with a tubular frame and hand-formed aluminium body.
