The Alfa Romeo B.A.T. 7, 1954, one of a series of Berlina Aerodinamica Tecnica concepts designed by Franco Scaglione. Nuccio Bertone added ideas from his experience working on wing profiles in the aeronautical industry resulting in the shape of the large, curved tail fins. The car's drag coefficient was 0.19, still impressively low, but revolutionary for the time.
