sedan

The modern usage refers to a specific body style of automobile characterized by a three-box configuration, where the engine, passenger, and cargo areas are separate compartments. It is typically contrasted with hatchbacks or coupes based on the presence of a fixed roof and a distinct trunk. Historically, the term describes a human-powered transport device. This archaic form consists of a cabin carried by porters, reflecting a status of luxury or necessity for those unable to walk, which informs the enclosed nature of the modern car variant.
