What is the difference between sedans and other cars ? – Literature & LanguageReport
What makes a sedan (or saloon car) unique to other cars is that its car body is divided into three areas known as boxes, which are separated by physical walls. The first box is the area that the engine is housed in, the second box encompasses all of the driver and passenger seats, and the third box is the trunk/boot. In station wagons and hatchbacks, there are only two actual boxes, as the trunk/boot is not separated from the passenger area by a physical wall and so is considered part of the passenger area.
