What exactly does the model data mean, and what does the model refer to

I'm a professional. I talked a lot on the first floor, and I didn't know if I was fine.

Vehicle Model: A number consisting of phonetic letters and Arabic numerals assigned to a class of vehicles to identify them. According to the national standard 9417-88, the domestic automobile model should be able to indicate the brand, type and main characteristic parameters of the car. Refers to the name given by the manufacturer to a vehicle of the same type, brand, type, series and body type.

There are five parts to the content of a vehicle code:

1. Enterprise name code;

2. Vehicle class code;

3. Main parameter code;

4. Product serial number;

5. The company sets its own code.

Automobile models include: small cars, mini cars, compact models, medium models, premium models, luxury models, sedans, CDV models, MPV models, SUVs and other models.

There are several types of cars - sedans.

Sedans are divided into mini cars, small cars, compact cars, mid-size cars, medium-large cars, and luxury cars, and the comfort and spaciousness vary depending on the class and price. You can choose the right car according to your economic situation and needs.

There are several types of models - SUVs

There are several types of models - MPVs

MPV refers to a multi-purpose car, in the Seattle movie in Beijing, Wu Xiubo drove an MPV, with wide space and strong comfort, suitable for carrying a family to travel in a car.

There are several types of models - sports cars.

A sports car is a symbol of wealth to a certain extent, and it is also a car with high speed and a low chassis. There are many kinds of sports cars according to classification, which can be divided into coupes, convertible sports cars, coupes, coupes, etc. according to the body structure, and can be divided into civilian sports cars, luxury sports cars, supercars, etc. Sports cars are common in many TV and movies, and the most expensive sports car is the Bugatti Vealine, which is worth more than 30 million.

There are several types of vehicles - pickup trucks.

A pickup truck is a model that combines sedans and vans, with the comfort of a sedan, a certain amount of power, and the ability to carry goods. Pickup trucks are very common in the United States and are very popular models among the American people.

The models I understand are those that are distinguished by the size, purpose, and size of the car: small car, micro car, compact car, medium model, premium model, luxury model, sedan model, CDV model, MPV and other models.

Various parameters of the car:

1. Length, width and height, length, width and height are the dimensions of a car, usually used in millimeters, and the body length is the distance between the most protruding position of the front bumper and the most convex position of the rear bumper. The width of the body is the distance between the most protruding positions on the left and right sides of the body. The height of the vehicle is the position of the highest section from the ground to the top of the vehicle, but does not include the length of the roof antenna;

2. Wheelbase, the wheelbase of the car is the distance between the center point of the two adjacent front and rear wheels on the same side, that is, the distance between the center point of the front wheel and the center point of the rear wheel, in millimeters;

3. The wheel base is divided into the front wheel base and the rear wheel track, and the wheel base is the distance between the center of the left and right wheels, usually in millimeters, and the wider wheel base has better lateral stability and better handling performance. The wider the wheel landing position, the better the driving stability;

4. The minimum ground clearance, the minimum ground clearance of the car is the distance between the lowest point of the automobile chassis and the ground on the horizontal plane, usually in millimeters, the ground clearance of different models is not the same, the larger the ground clearance, the better the passability of the vehicle;

5. Wind resistance coefficient, air resistance is the largest and most important external force encountered when the car is driving. The drag coefficient can be measured in a wind tunnel.

Various parameters of the car:

Length, width and height.

As the name suggests, the so-called length, width and height are the dimensions of a car, usually used in millimeters (mm), and the specific measurement method is as follows: Body length is defined as: the distance between the two extreme points in the length direction of the car, that is, the distance between the two points from the most protruding position of the front bumper to the most convex position of the rear bumper.

The width of the car is defined as the distance between the two extreme points in the width direction of the car, that is, the distance between the most protruding positions on the left and right sides of the body. According to the general rules of the industry, the width of the body does not include the width of the left and right rearview mirrors, that is, the width of the rearview mirror after folding.

Vehicle height is defined as the distance from the ground to the highest point of the car. The highest point is the highest point on the top of the body, but does not include the length of the roof antenna.

Wheelbase. To put it simply, the wheelbase of the car is the distance between the center points of the two adjacent front and rear wheels on the same side, that is: the distance between the center point of the front wheel and the center point of the rear wheel is the distance between the front wheel axle and the rear wheel axle, referred to as the wheelbase, and the unit is millimeters (mm).

Front track Rear track.

The wheel base is divided into front track and rear track, and the wheel base is the distance between the center of the left and right wheels, usually in millimeters (mm), and the wider track has better lateral stability and better handling performance.

The wider the wheel landing position, the better the driving stability, so the wheel base of off-road vehicles is wider than that of general sedan models.

Minimum ground clearance.

The minimum ground clearance of the car is the distance between the lowest point of the car chassis and the ground on the horizontal plane, usually in millimeters (mm), and the ground clearance is different for different models. So usually the ground clearance of off-road vehicles is greater than that of sedans.

Drag coefficient. Air resistance is the largest and most important force encountered by a car while driving. The air resistance coefficient, also known as the drag coefficient, is an important factor in calculating the air resistance of a car.

The drag coefficient can be measured in a wind tunnel. When the vehicle is tested in the wind tunnel, the wind speed is used to simulate the speed of the car when driving, and then the test instrument is used to measure how much strength the car needs to resist the wind speed, so that the car will not be blown backwards by the wind. After measuring the required force, and then deducting the friction between the wheel and the ground, the rest is the wind resistance, and then the so-called drag coefficient can be calculated using the aerodynamic formula.

Engine power, displacement, fuel consumption.

The Three Laws:

1. Buy late or not early The "late" here has two meanings.

First, the best time to buy a car generally appears at the end of the year, and practical problems such as year-end impulse, top task, rebate point, inventory pressure, and new car launch force automobile companies and dealers to take preferential and price reduction measures. This is a market pattern that has been proven for many years. During the year, it is better to buy a car late, preferably at the end of the year.

Buy early and enjoy early, but buy early and regret early. I bought the car at the beginning of the year, and now I look at it again, ** is a little worse. Second, after the new car is launched, there must be a drop.

So it's best to buy a new car later after it comes out, you can wait, and it's not too late to buy it after he has lowered it.

Second, buy more not buy less large output, high market share, buy more consumers of the car, should have won the market and more consumer recognition, after the market and consumers of the double test, indicating that the quality and performance is reliable, and more reasonable. Such a car is easy to maintain, and the after-sales service is guaranteed. When choosing a car, you also have to look at the dealer.

The 4S store has a large sales volume and good after-sales service, so it is best to buy a car at the 4S store. In the absence of an expert to advise you, this aspect of the factor can be used as a reference.

3. Buy up, don't buy down This law is also understood from two aspects. Cars** show a sharp downward trend, do not buy; The model you choose is unstable, and it will drop again and again, so don't buy it. Some models** are relatively stable, such as FAW-Volkswagen New Bora, Shanghai Volkswagen Passat and so on.

Large manufacturers and brands generally do not frequently reduce prices, so you can consider it when buying a car.
