The Berlinetta Aerodinamica Tecnica 7, or B.A.T. 7, took up the styling dictates of the previous model, the B.A.T. 5, and worked them to the limit. once again the car was based on the general idea of the 1952 Abarth 1400 coupe, wîth Alfa 1900 Sprint mechanics. For this 1954 design, as for the other B.A.T. models, though less evidently, Bertone added some elements from his experience working on wing profiles in the aeronautical industry. The result was the exaggerated shape of the large, curved tail fins.
