Why it matters

The Saponetta, officially the Sport Internazionale, was Bandini's most successful car and closed the marque's most successful period. It was a small Crosley-based twin-cam sports-racer built to the international sports-car formula and sold widely in the United States.

History

Introduced in 1957 to replace the Siluro in Italy, the Saponetta had an aluminium barchetta body made by Bandini itself. It started in the 750 cc class and was later offered with 850 cc and 1000 cc engines; the 1000 cc unit was built entirely by Bandini and is quoted at 90 hp at 7200 rpm with a Bandini four-speed gearbox. Two cars started the 1957 Mille Miglia and retired. Older Siluros could be converted to Saponetta specification.
