During World War II, American government restrictions on in-house design departments at Ford, General Motors, and Chrysler prevented official work on civilian automobiles. Because Loewy's firm was independent of the fourth-largest automobile producer in America, no such restrictions applied. This permitted Studebaker to launch the first all-new postwar automobile in 1947, two years ahead of the "Big Three." His team developed an advanced design featuring flush-front fenders and clean rearward lines. The Loewy staff, headed by Exner, also created the Starlight body, which featured a rear-window system that wrapped 180° around the rear seat.
