Question: what is the difference between an estate car and a hatchback?
Answer: The distinguishing feature of a hatchback is a hatch-type rear door that opens upwards and is hinged at roof level (as opposed to the boot/trunk lid of a saloon/sedan, which is hinged below the rear window). ... An estate/wagon typically differs from a hatchback by being longer (therefore more likely to have a D-pillar).
