In the United States, this vehicle is known as the sedan. However, if you travel to those areas where British English is spoken, you would come to know that it is not known as the sedan there but as a saloon. The sedan is known as one of the most common body styles of an automobile. The most basic parts of a sedan comprise of a hood that covers the engine in the front, the passenger car itself, and a separate trunk for luggage which is typically found at the rear of the vehicle.
