The main differences between hatchbacks and saloons (also sometimes called sedans) are the car’s boot and overall structure.
A hatchback has boot space inside the car, just behind the rear seats. This is accessed through a third or fifth door, which offers more practicality thanks to the bigger boot aperture. Saloons, however, have the boot as a separate part that sticks out. Saloon boots tend to open below the rear window.
A saloon has three ‘compartments’; one for the engine, one for the passengers and one for the cargo (boot). A hatchback has two compartments: one for the engine and one for the passengers and cargo.
This doesn’t mean a saloon has more seating space. A hatchback can also carry up to five passengers, but you can put the seats down for increased boot space – offering a bit more flexibility.
