The MEL was one of three new engine families introduced by Lincoln and Ford in 1958. The others were the FE (Ford Edsel) and SD (super duty), the latter being large and extra powerful, slow-revving engines engineered for heavy-duty work trucks. The FE engine saw its use in the Edsel, a model which was introduced to the vehicle lineup by Ford, described as a car which blended design features of the Ford and Mercury lines combining them with its own individual styling. Further several new Lincoln vehicles, such as the Continental luxury sedan and coupe, as well as the all-new four-seat Thunderbird of the same year, which were brought to market utilizing the new engines.
