Detroit Dud is a term used to describe two cars produced by the Ford Motor Company in the 1950s and 1960s. The two cars are the EDSEL and the LEMON. The EDSEL was a car that was produced from 1958 to 1960 and was considered a commercial failure due to its unpopular design and high production costs. The LEMON was a car produced from 1961 to 1963 and was also considered a commercial failure due to its poor quality and reliability. Both cars were considered Detroit Duds due to their lack of success in the market.
