Car, what does it mean to have 3 phases and 2 phases?

A sedan is a car with a protruding trunk (sedan: engine compartment, passenger compartment, trunk).

A hatchback is a car that does not have a protruding trunk (hatchback: engine compartment, passenger compartment).

Calculated by the distance of the door.

2 phases 2 doors apart.

There are 3 equals.

3 boxes are with a trunk.

and the recoil that is separated.

HatchbackThe front of a hatchback is no different from a sedan, and the role is the same. The difference is that this kind of car extends the passenger compartment to the rear at an approximate equal height, and combines the rear baggage compartment and the passenger compartment into one, reducing it to two "compartments" of the engine compartment and the passenger compartment. Since hatchbacks also have separate front engine compartments, they have the same good frontal impact protection as sedans, regardless of whether they are standard or short-headed, and meet current frontal crash protection requirements.

Many of the Beverly, Xiali and Alto on the street are hatchbacks. The hatchback has a wide rear door at the rear, making it flexible and versatile: by folding down the flat rear seats, you get much more cargo space than a sedan, which can be used to transport many large appliances and household goods.

For example, the Beverly hatchback, with the rear seat folded, increases the luggage compartment volume from 324 litres to 1,146 litres, and even the Alto's rear luggage compartment can fit a large 29-inch color TV with a box, an automatic washing machine and a freezer. However, sedans in the same price range, such as Santana and Jetta, have a constant trunk volume, and it is almost impossible to carry large items with the car, which limits the convenience of the car. Although there are still many people in our country who are not accustomed to hatchback cars and think that it does not look like a car, with the acceleration of China's internationalization process and the actual car situation in the city, this kind of short size and flexible use of cars will become more and more popular.

Sedans Nowadays, the common sedan is generally a sedan, and the reason why it is called a sedan is because its body structure is composed of three "compartments" that are closed to each other for different purposes: the engine compartment in the front, the passenger compartment in the middle of the body, and the luggage compartment in the rear. Initially, the engine compartment was only used to house the engine, transmission, steering, braking and other important assemblies of the car, and later, the role of the engine compartment became more and more important, and the engine compartment of modern cars also shouldered the important mission of passive safety, that is, when the car had an unexpected frontal collision, the engine compartment would bend and deform to absorb the huge energy generated by the collision, reduce the violent impact of the collision on the people inside and outside the car, and play a role in protecting the occupants of the car.

The design of the passenger compartment in the middle of the body is firm and rigid, and the deformation of the compartment is small when encountering the impact of collision and rolling, which can prevent the door from opening and throwing out passengers by itself in motion, reduce the risk of injury caused by the deformation and crushing of the compartment, and is conducive to the occupants can open the door smoothly after the car accident to escape. The rear luggage compartment is not only responsible for the placement of luggage, it also shoulders the function of reducing the damage caused by rear-end collisions of rear vehicles. The sedan is high in the middle and low at both ends, symmetrical from the side, and the shape is beautiful and generous.

The disadvantage of a sedan is that it is long in size, and it is not very convenient to drive and park in large cities with heavy traffic. Our common Santana and Jetta are all sedans.

The two-box car does not have an independent trunk, and its trunk is only a small space at the bottom of the rear seats, and the ability to store items is small, while the three-phase car has an independent trunk and has a relatively large capacity.

Viewed from the side of the car, the car appears to be composed of three boxes: the engine compartment, the passenger compartment, and the trunk. Hatchbacks, such as the Polo, lack the trunk at the back.

The sedan has more trunk, more things, larger relative volume, slightly larger fuel consumption (relative to hatchbacks), hatchbacks have no trunk, slightly less stuffed, relatively small size, parking in the city or doing anything is relatively flexible, fuel consumption is also smaller, and the space is smaller!

The difference between a hatchback and a sedan is:

1. The former is an official (business) car, and the latter is a family car (you see that unit uses a hatchback, unless it is an off-road vehicle);

2. The former is fashionable, the latter is practical;

3. Hatchbacks of similar models are far more popular than sedans: from Citroen to Sail, from Fit to Polo, from Yida to Tiida, etc., which car sedan can sell more than hatchback?

Why is that?

4. Let's talk about practicality: in a word, the two compartments that can be installed in the sedan can be installed, and the vast majority of the sedans (including Mercedes-Benz and BMW) that can be installed in the hatchback cannot be installed.

For example, in the case of the hatchback mentioned above,-- go to the farmhouse and buy a bouquet of 1-meter-high wax plums or plants.

--Coffee table, light cabinet, 34-inch TV (with box), ordinary refrigerator, two or three bicycles or mountain bikes, including extra decoration or rice, the sedan is far inferior to the hatchback

If you want to be beautiful, buy a sedan!

There is no tail is a hatchback, there is a tail is a sedan, for example, Chery QQ and Panda and Ao Kuo are all hatchbacks, now there are many cars in the hatchback, and the brands are not introduced one by one, such as the most ordinary Volkswagen 2000 Ah Passat, Suteng, Audi A6A8 and so on are all sedans.
