The 1948 Tucker Sedan or Tucker '48 Sedan (initially nicknamed the Tucker Torpedo) was an advanced automobile conceived by Preston Tucker and briefly produced in Chicago in 1948. Only 51 cars were made before the company folded 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. Speculation exists that the circumstances which brought the Tucker Corporation down were contributed to by the Big Three automakers and Michigan senator Homer Ferguson.
