1956 Siata 300 BC Barchetta

Coachwork by Bertone

SIATA, short for Società Italiana Applicazioni Techniche Auto-Aviatorie, was founded in 1926 by amateur racing driver Giorgio Ambrosini. Initially, the company focused on tuning FIAT cars and selling performance parts. After World War II, SIATA began manufacturing its own engines and gearboxes, producing a diverse range of models, including some with V8 engines. Known for their driving pleasure and competition success, SIATA cars were particularly popular in the United States, where the Barchetta model was marketed as the “Spyder.”

Introduced at the 1952 Geneva Salon, the 300BC Spyder was designed by Mario Revelli de Beaumont and built by Bertone. This model targeted American enthusiasts of small Italian sports cars. De Beaumont, a prominent designer, had worked with many prestigious Italian styling houses, including Pininfarina. Around 50 units of the 300BC Spyder were produced, with the first 40 by Bertone and the final 10 by Turin-based Motto, renowned for their work on Ferrari bodies and the Porsche Abarth GTL.

The 300BC featured large, finned Stanguellini brakes and could be equipped with Crosley or Fiat-derived engines. Aimed at competition, it boasted excellent handling and maneuverability. The highly tunable Fiat engines provided ample power, making the lightweight 300BC a potent performer.
