What are some categories of cars and how should they be distinguished?

Cars can generally be divided into six categories according to their purpose: 1 sedan, also known as a minibus, generally no more than 9 seats (including the driver's seat). 2 Buses, with more than 9 seats (including driver's seats), including city buses, road passenger buses, tourist buses, etc. 3 Cargo vehicles, commonly known as trucks, are mainly used to transport goods.

(1) Ordinary trucks: divided into light (less than 5t), medium (greater than 4-8t) and heavy (greater than 8t) trucks according to their payload. ( 2) Special vehicle: It is a variant of ordinary trucks, with special cargo boxes, and takes into account the special needs of cargo loading and transportation. There are insulated trucks, can trucks, etc.

Classified by purpose: it can be divided into family cars, business cars, off-road vehicles, sports cars, trucks, etc.Classified according to the body structure: it can be divided into cars, SUVs, MPVs, vans, trucks, etc. Classified according to the power source: it can be divided into traditional fuel vehicles, hybrid vehicles, pure electric vehicles, fuel cell vehicles, etc.

. Sports car: It belongs to a type of car with low chassis, smooth lines and outstanding power. Its biggest feature is the constant pursuit of speed limits. There are many classifications of sports cars. According to the body structure, they can be divided into coupes, convertible sports cars and two-door sports cars, and according to the value, they can be divided into civilian sports cars and super sports cars.

What is the difference between a hatchback and a sedan

Distinguish from the side: the rear of the hatchback is relatively smooth, the trunk part and the cab part are combined, and the sedan has a separate trunk.

The noise of sedans is generally smaller than that of hatchbacks, because the cockpit of the sedan is separated from the trunk, and the noise of the rear wheels is separated in the trunk. The weight of the hatchback is relatively concentrated in the front of the car. The tail of the sedan is longer and the tail weight is heavier, so the balance of the sedan will be better.

The differences between hatchbacks and sedans are as follows: Compared with the same car, the hatchback has more space in the rear row than the sedan. In the same kind of car, the capacity of the three-box tailbox is larger than that of the two-box. The hatchback model does not have a tail box. When turning, it is lighter than the sedan, and it is also more flexible to park and parallel.

Cars Is there any difference in the types?

Ordinary transport vehicles: divided into cars, buses and trucks. Both cars and buses are used to carry people, and trucks are used to pull goods. Cars can be divided into: mini cars, light cars, mid-range cars, medium and high-end cars, and high-end cars according to the engine displacement. According to the purpose: This classification is simple and can be roughly divided into two categories.

Car models include: small cars, mini cars, compact cars, medium models, high-end models, luxury models, sedan models, CDV models, MPV models, SUV and other models.

Classified by purpose: it can be divided into family cars, business cars, off-road vehicles, sports cars, trucks, etc. Classified according to the body structure: it can be divided into cars, SUVs, MPVs, vans, trucks, etc. Classified according to the power source: it can be divided into traditional fuel vehicles, hybrid vehicles, pure electric vehicles, fuel cell vehicles, etc.

The difference between mini cars and small cars

1. Different displacements Mini cars: The displacement of the engine mainly includes 0.8L, 0L, 0T and 2L versions. Small car: a model with a displacement of about 0 to 3. Medium-sized vehicles: The engine displacement is usually from 0 to 0 liters.

2. Different displacements: the engine displacement of mini cars is between 0.8~2L; the engine displacement of small cars is between 0~5L. The body length is different: the length of the mini car is less than 3700mm; the length of the small car is between 3700 and 4300mm. The wheelbase is different: the wheelbase of mini cars is between 2000~2300mm; the wheelbase of small cars is between 2300~2600mm.

3. Mini cars and small cars are distinguished according to the size of the wheelbase of the whole vehicle. Small cars generally refer to the A0-class car in the A-type car. The wheelbase of this car is generally between 2.2 meters and 3 meters (some models are outside this range) and the engine displacement is 1 liter to 3 liters.
