After WW2, Nash resumed production in 1946 for the Post-War Ambassador. From 1946 until 1948, the Ambassador was largely similar to the Pre-War cars, but in 1949, Nash introduced their updated 'Airflyte' steamlined styling. This new styling was offered on all Ambassadors until 1952 when the Ambassador received a styling update in collaboration with Pininfarina. Over the course of production, a range of open and closed body styles were offered, as well as a choice of inline six or V8 engines. In 1954, Nash merged with Hudson to create the American Motors Corporation, which continued to produce the Nash branded Ambassador until 1957. After that, the model would transition between makes, but is commonly known as the AMC Ambassador.
