Hatchback is a kind of car design. The most obvious feature of a hatchback car is that it has a vertical tailgate or oblique rear window door. This type of car is very common as this design is used in most of the models. Hatchback cars have other names---three doors car or five doors car. This type of design can maximize the limited space of a car and increase the flexibility of the vehicle and this is significant in some countries which have a huge number of traffic jams. Most hatchback cars have a collapsible back row. Under the situation of no one sitting in the back row, it can increase the space of the cargo. This advantage gets a huge practicability.
