A hatchback is a type of CAR that has a rear door that opens upwards, allowing for easy access to the cargo area. It typically has a sloping roofline and a two- or three-box design. The term 'hatchback' is derived from the fact that the rear door is hinged at the roof, allowing it to be opened like a hatch. Hatchbacks are often smaller than other types of cars, making them more fuel efficient and easier to maneuver in tight spaces. They are also popular among those who need to transport large items, as the rear door allows for easy loading and unloading.
