A sedan is a passenger car in a three-box configuration with A, B & C-pillars and principal volumes articulated in separate compartments for engine, passenger and cargo. The passenger compartment features two rows of seats and adequate passenger space in the rear compartment for adult passengers. The cargo compartment is typically in the rear. It is one of the most common car body styles. The primary purpose of the sedan is to transport people and their baggage on ordinary roads. Sedan versions of the automobile body style have a central pillar (B-pillar) that supports the roof and come in two- and four-door versions. Sedans usually have a two-box or three-box body.
