The Packard Super Eight was the larger of the two eight-cylinder luxury automobiles produced by the Packard Motor Car Company of Detroit, Michigan. It shared frames and some body types with the top model Packard Twelve. The 1933-1936 Packard Super Eight was a big classic. In 1937, it was reduced to a smaller and lighter design. Following the discontinuation of the Sixteenth Series Twelve after the 1939 model year, a new Custom Super Eight One-Eighty was derived from the Super Eight as the new top car range. The Super Eight was renamed the Super Eight One-Sixty starting a naming convention change in 1940. These two models shared most mechanical components including the 160 HP straight Eight engine and continued to be regarded as the Senior Packard.

The Packard Twelve was a range of V12-engined luxury automobiles built by the Packard Motor Car Company in Detroit, Michigan. The car was built from model year 1916 until 1923, then it returned 1933 until 1939. As a sign of changing times, the majority of second generation Packard Twelves received standard bodywork, with custom bodywork gradually losing favor. Many of the custom cars were actually only "semi-customs", with Dietrich assembling Packard-made bodies with special touches.
