In 1956, American Motors created an all-new Rambler, using the 108" wheelbase chassis. The car was a major redesign of the long-wheelbase four-door sedans and station wagons. The short- wheelbase cars were dropped.

The Rambler body was sold under the Nash and Hudson brand names. The new car came only as a 4-door model, but it was offered as a 4-door post sedan and station wagon as well as a new 4-door hardtop sedan. In an industry first, Rambler introduced a 4-door hardtop station wagon. The Rambler Six was offered in entry-level "Deluxe" trim, in midrange "Super" and highline "Custom" trim.
