What do hatchback and sedan mean?

[DiMatthew]

Compartments refer to independent spaces. The three compartments of a sedan are the engine compartment, passenger compartment, and trunk. A hatchback has an independent engine compartment, but the passenger compartment and trunk are connected together. Characteristics of hatchbacks: The front part of a hatchback is no different from that of a sedan, and their functions are the same. The difference lies in the fact that this type of car extends the passenger compartment approximately to the same height backward, integrating the rear luggage compartment with the passenger compartment, reducing it to two compartments: the engine compartment and the passenger compartment. Therefore, they are mostly used for small and compact cars. Characteristics of sedans: Sedans are high in the middle and low at both ends, symmetrical from the side view, with a beautiful and elegant shape. The disadvantage of sedans is their long body size, making them less convenient to drive and park in crowded big cities. Common models like the Santana and Jetta are sedans.
