Alfa Romeo BAT cars were three design exercises to study extreme aerodynamics as applied to sports coupes. The cars were built on Alfa 1900 Sprint chassis. B.A.T. stands for Berlina Aerodynamica Technica. The dark gray BAT 5 debuted in 1953; the silver blue BAT 7 was introduced a year later and the silver BAT 9 appeared in 1955 at the Turin Auto Show.
