The Tucker 48, commonly but incorrectly referred to as the Tucker Torpedo, was an automobile conceived by Preston Tucker while in Ypsilanti, Michigan and briefly produced in Chicago, Illinois in 1948. Only 51 cars were made including their prototype before the company was forced to declare bankruptcy and cease all operations on March 3, 1949, due to negative publicity initiated by the news media, a Securities and Exchange Commission investigation, and a heavily publicized stock fraud trial. Tucker suspected that the Big Three automakers and Michigan Senator Homer S. Ferguson had a role in the Tucker Corporation's demise.
