The Packard 180 was introduced for the 1940 model year (18th series) by the Packard Motor Car Company to replace the discontinued Packard Twelve as their top-of-the-line luxury model. The correct name of the model was Custom Super Eight One-Eighty. The car was derived from the Packard Super Eight One-Sixty.

Packards of all series (110, 120, 160, 180) shared similar body styling in 1940 (which some later said led to a "cheapening" of the once-exclusive luxury marque), using the same bodies with hoods and front fenders of different length to meet their respective chassis. Thus the 160 and 180 got identical bodies.

The Packard Pacific is an automobile manufactured by the Packard Motor Car Company  for the 1954 model year.  It replaced the Mayfair and was sold exclusively as a two-door hardtop.

The Mayfair, Packard's first hardtop offering, was created for the 1951 model year in order to keep in competition with Cadillac, Buick, and Imperial from Chrysler, whose hardtop sales were booming. The Mayfair was named after the exclusive Mayfair district of London. In renaming it as the Pacific, Packard associated the model with its personal luxury car offering, the Caribbean. Both the Mayfair and Pacific shared the same straight-eight engines  with top-of-the-line, or "senior" Packards.

The Pacific came standard-equipped with Packard's Ultramatic automatic transmission. 1189 Pacific hardtops were built before production concluded for the 1954 model year. Starting in 1955, Packard renamed its senior hardtop the Four Hundred.
