High Quality Content by WIKIPEDIA articles! The Packard 180 was introduced for the 1940 model year (18th series) by the Packard Motor Car Company to replace the discontinued V-12 as their top-of-the-line luxury model. Correct name of the model was Custom Super Eight One-Eighty. The car was derived from the Packard Super Eight One-Sixty with which it shared the complete running gear including the in-line eight-cylinder, 356-cubic-inch (5,830 cc) engine that developed 160 horsepower. It was advertised as the most powerful eight-cylinder engine offered by any automobile manufacturer in 1940. (By contrast, the Cadillac 346 cubic inch V-8 developed 150 hp).
