Beside this, what do you mean by hatchback cars?
A hatchback car is a vehicle that has a large door in the back that swings upward, While many other models also use this type of door, a hatchback car is traditionally looked at as a small coupe- to sedan-size car with a raise-open door in the back instead of a trunk, which usually gives it more storage space.
Also, why is a hatchback called a 5 door? A 5-door car has the same 4 doors but also has a hatch in back to access the storage area. That's the 5th “door". Not a very convenient door for getting into the passenger compartment, but you can crawl forward to the seats in a pinch. This type is called a hatchback.
Then, what's the difference between a hatchback and a sedan?
The main difference between a sedan and the hatchback in how the car body (trunk) space is partitioned. With a hatchback, there is no trunk per seat. A hatchback car has space back the rear passenger seat that is easy through a rear door or window; often referred to as a “hatch,” “lift gate,” or any other term.
What is the difference between a hatchback and an estate car?
Estate cars are usually based on saloons or hatchbacks and tend to be a little longer than the cars on which they're based. The obvious advantage is the increased boot space over an equivalent saloon but, for some fans, the longer roof afforded by estates makes them more desirable than other options.
