1, horse body. The earliest body modeling was to transplant the carriage directly to the car. 1886, Daimler and Ben Ci trial-produced 1.5 horsepower (1 British horsepower = 745.7W) and 0.85 horsepower single-cylinder gasoline engines respectively, and successfully trial-produced the first automobile.

2. Box. Like the shape of a box. 19 15, the model t of Ford motor company in the United States changed from the top to the trunk. The trunk is rectangular and looks like a big box with doors and windows. People call this kind of car "box car", which lays the basic shape of the car in the future.

3. Beetle body. In 1930s, in order to improve the speed of automobiles, aerodynamic principles were applied to reduce the drag coefficient. The car body height gradually decreases to 1.4m, and the car width gradually increases. The cross section of the car body is deformed from square to oval, thus reducing the windward area.

4. Hull. In 1950s, in order to create a comfortable and spacious ride space, boat-shaped cars appeared and became the mainstream of contemporary car modeling. 1949, the V8 of Ford Motor Company created the shape of the hull for the first time. The important feature of the boat-shaped car body is the application of ergonomics to design the car body, and the riding position is placed in the middle of the car body, with the least vibration.

5. Fish-shaped body. In order to overcome the defect that the tail of a boat-shaped car extends backward too much and strong air vortex will be generated when the car is driving at high speed, people have developed a fish-shaped car like a fish back. 1952, the Buick brand car of General Motors of the United States started the era of fish-body cars.

6. Wedges. Although the "fish-shaped duck tail" model partially overcomes the air lift when the car is driving at high speed, it does not fundamentally solve the lift problem of the fish-shaped car. After a lot of exploration and experiments, the designer finally found a new pattern-wedge.

The present situation of automobile appearance

Automobile modeling design is undoubtedly very important. Since the day the car was born, people have been constantly improving it, and it has obvious brand of the times. It can be said that the history of automobile modeling changes is also the history of automobile fashion evolution and technology evolution. With the progress of science and technology, the car body is more and more beautiful and has more and more functions, which is more and more in line with the requirements of aerodynamics.

Nowadays, the design of automobile body can be said to be more and more mature, but it is basically based on wedge-shaped body, which integrates the appearance characteristics of other bodies and becomes more practical, fashionable and versatile. With the progress of science and technology, the mechanical parts of automobiles, such as engines and gearboxes, are getting smaller and smaller, electronic technology is widely used in automobiles, and the body design of automobiles is becoming more and more flexible and diverse.
