What is the change in the shape of the car now compared to the earliest cars

More rounded, streamlined design reduces wind resistance and conforms to the public aesthetic.

1. The body of the horse model. The earliest car body shape, that is, the carriage carriage was transplanted directly to the car. In 1886, Daimler and Benz trial-produced horsepower (1 inch horsepower = watt) and horsepower single-cylinder gasoline engines respectively, and successfully trial-produced the first automobile.

2. A box-shaped body. It has the shape of a box-like body. In 1915, the T model car of the American Ford Motor Company was changed from the canopy to the envelope, the envelope was rectangular, its appearance was very similar to a large box, and equipped with doors and windows, people called this kind of car "box car", which laid the basic shape of the car in the future.

3. Beetle-shaped body. In the 30s of the 20th century, in order to increase the speed of automobiles, the principle of aerodynamics began to be applied to reduce the drag coefficient. The height of the car is gradually reduced to meters, and the width of the car is gradually increased.

The body cross-section has been changed from square to oval, which reduces the windward area.

4. A ship-shaped body. In the 50s of the 20th century, in order to create a comfortable and spacious riding space, a boat-shaped car appeared, and thus became the mainstream of contemporary car styling. In 1949, Ford Motor Company's V8 sedan was the first to pioneer the shape of a boat-shaped body.

An important feature of the boat-shaped body is that it begins to apply ergonomics to the design of the body, placing the passenger position in the middle of the car with minimal vibration.

5. Fish-shaped body. In order to overcome the defect that the tail of the boat-shaped car sticks out too much backwards, and the strong air vortex effect occurs when the car is driven at high speeds, people have developed fish-shaped cars that resemble the back of a fish. In 1952, the "Buick" brand sedan of General Motors of the United States ushered in the era of fish-shaped cars.

6. Wedge-shaped body. Although the "fish-shaped ducktail" model partially overcomes the air lift of the car at high speed, it does not fundamentally solve the lift problem of the fish-shaped body car. After a lot of exploration and experimentation, the designers finally found a new model - the wedge.

Primitive stage- More than ten years after the advent of the automobile: At the beginning of the birth of the automobile, due to the low speed of the car, the air resistance was not considered at all during driving.

Late 90s of the 19th centuryPeople began to try to add streamlines to the body design, and the earliest aerodynamic cars appeared - shell-shaped cars, boat-shaped cars, etc.; Basic Model Stage - Complete Body Considerations (Wind & Rain & Comfort):

Emerged in the early 20th century"Airship" and "Teardrop"; Streamlining period: the long-tail streamlining stage - synthetic body, the emergence of the J-type car, from the J-type concept car to the end of World War II, this period is called the "J-type car era"; Broken wake streamline stage - K-type cars and L-type cars appeared; Optimization period: 70s, body detail optimization, 80s, overall optimization (shape optimization) of the body.

In 1933, Dr. Polscher of Germany designed a car that resembled the shape of a Beetle.

Polscher maximized the strengths of the Beetle's shape, making it the king of its kind, and the "Beetle" became synonymous with the car.

Due to the Second World War, the Beetle was not really mass-produced until 1949, and sold well all over the world with a record of more than 20 million units produced in one model.

The success of the Ford V8 car not only made a breakthrough in appearance, but also first applied ergonomics to the design of the car, emphasizing the design of a car that is easy to maneuver and comfortable to ride with people as the main body.

I guess it's from the aerodynamic aspect!?

The primitive stage - more than ten years after the advent of the car:

At the beginning of the birth of the automobile, due to the very low speed of the car, the air resistance during the driving of the car was not considered at all, and the body design of the car was to follow the shape of the carriage;

At the end of the 90s of the 19th century, people began to try to add streamlining to the body design, and the earliest aerodynamic cars appeared - cannonball-shaped cars and boat-shaped cars;

Basic phase – full body considerations (shelter from the wind and rain and comfort):

In the early 20th century, the "airship type" and the "teardrop type" appeared;

Streamlined period:

The long-tail streamlined stage - the emergence of the synthetic body, the J-type car, from the J-type concept to the end of World War II, this period is called the "J-type car era";

Broken tail streamlined stage - K-type cars and L-shaped cars appeared;

Optimization Period:

The 70's detailed optimization of the body.

The 80's overall optimized (shape optimization) body.

First of all, it can carry people, and then it is rainproof--- windproof--- cold--- beautiful, --- reduce wind resistance.

The scope of your question is too broad、Can you give a specific model。

It has gone through many stages, at first it was a carriage type, then it became a van type, and then it became a carapace type, a boat type, and a fish type.

It has gone through seven phases, the horse car, the box car, the Beetle, the fish car, the boat car, the wedge car, and the modern car.

There were many different stages, such as the Arima type car, but also the box type, and then the Beetle, the fish car, the boat type car, and so on.

What is the development of the shape of the car and its influencing factors?

Compared with the earliest cars, the shape of today's cars is mainly streamlined, and the drag coefficient is reduced. Not only aesthetics second.

The popular type, drag coefficient for home use cars has been reached, so the inevitability of reducing fuel consumption, the side is showing sharp lines, which is called the waist line in the industry! There is also the X6 that BMW withdrew from Honda, and the Gostu SUV from Honda has a fastback design.

There are three essential elements to determine the shape of a car, namely mechanical engineering, ergonomics, and aerodynamics. The first two elements are of great significance in determining the basic skeleton of the automobile construction, especially in the early stage of design, and are more constrained by these two elements.

The evolution of the shape of the car.

1. Horse type car 2, box car 3, Beetle car 4, three-box (ship) car 5, fish type car.

6. Wedge car.

The original car was a steam engine, like a four-wheeled wooden flatbed with a steam engine. Later, the internal combustion engine appeared, and the performance of the car was rapidly enhanced. At this time, the shape and architecture of the car were still based on the previous horse-drawn carriage.

Later, the design of the car finally became independent, and specially designed suspension systems and body structures began to appear, resembling the statue in the town of Cars. Later, people began to pursue individuality, and tried their best to make various shapes on the basis of the steel tube frame, basically doing what they thought was good-looking, except for considering the sturdy accident, they did not consider safety and aerodynamic performance at all. At this time, the suspension technology of automobiles also developed greatly, thanks to the development of motorsports.

It was at this time that famous car manufacturers such as Ferrari appeared. Later, the rear wing appeared, which was the first time that the automobile used aerodynamic technology, but these aerodynamic forces were not effectively calculated, and the height and size of the rear wing were installed completely according to their own preferences, so there were various exaggerated and amazing rear wings during this period. Finally, aerodynamic technology in automobiles began to develop in the direction of rationalization and practical use, also thanks to motorsport.

During this period, aero technology was not perfect enough, so a large number of wedge-shaped cars appeared, such as the super handsome chrono DMC-12 in "Back to the Future". After that, the aerodynamic technology was more perfect, and streamlined bodies began to appear, and the wind resistance of the body was further reduced; In the world of motor racing, various aerodynamic fins have been developed to allow the body to generate air downforce several times the gravitational force of the vehicle. In this process, in addition to the previous Bernoulli aerodynamic theory, the ground-effect aerodynamic theory was discovered, and from then on, various shapes of air diffusers and other aerodynamic components began to appear on the body.

In terms of body structure, people slowly began to understand the lack of high rigidity of steel tube frames, and began to design load-bearing bodies that could absorb and disperse energy, and as a result of this progress, the number of accidents involving internal injuries to occupants in car accidents was significantly reduced.
