Forerunner of the modern sporting stations wagons, the Giulietta Promiscua prepared by the Colli body shop in 1956 had a pleasant and balanced line. The mechanics derived from the I series sedan, with a 1290cc twin-shaft engine in light alloy and 53 horsepower. Many cars were destined for the Italian Polizia Stradale. In total, 91 examples of Giulietta SW were manufactured.
