An experimental gas-turbine-engined prototype presented by Fiat in April 1954. Propulsion is provided by a two-stage centrifugal blower coupled to a two-stage turbine and a driving turbine linked to a geared reduction unit to transmit the movement to the wheels. Model tests in the Turin Polytechnic’s wind tunnel demonstrated the excellent streamlining of the saloon’s two-seater bodywork. Pratical tests were carried out on the runway of Turin’s Caselle airport.
