Sedan

[NANO]

A sedan  — is a passenger car in a three-box configuration with separate compartments for engine, passenger, and cargo.Sedan's first recorded use as a name for an automobile body was in 1912.The name comes from a 17th century development of a litter, the sedan chair, a one-person enclosed box with windows and carried by porters. Variations of the sedan style of body include: close-coupled sedan, club sedan, convertible sedan, fastback sedan, hardtop sedan, notchback sedan and sedanet/sedanette.The current definition of a sedan is a car with a closed body (i.e. a fixed metal roof) with the engine, passengers, and cargo in separate compartments.This broad definition does not differentiate sedans from various other car body styles, but in practice the typical characteristics of sedans are: a B-pillar (between the front and rear windows) that supports the roof two rows of seats a three-box design with the engine at the front and the cargo area at the rea a less steeply sloping roofline than a coupé, which results in increased headroom for rear passenger and a less sporting appearance.a rear interior volume of at least 33 cu ft (0.93 m3)It is sometimes suggested that sedans must have four doors (to provide a simple distinction between sedans and two-door coupes).However, several sources state that a sedan can have two or four doors.In addition, terms such as sedan and coupé have been more loosely interpreted by car manufacturers since 2010.When a manufacturer produces two-door sedan and four-door sedan versions of the same model, the shape and position of the greenhouse on both versions may be identical, with only the B-pillar positioned further back to accommodate the longer doors on the two-door versions.A sedan chair, a sophisticated litter, was an enclosed box with windows used to transport one seated person. Porters at the front and rear carried the chair with horizontal poles.Litters date back to long before ancient Egypt, India and China. Sedan chairs were developed in the 1630s. Reputable etymologists suggest the name of the chair very probably came through Italian dialects from the Latin sedere meaning to sit.
