Briefly describe the development of automobile appearance and its influencing factors.

The development of automobile body forms has mainly gone through several stages: carriage, box car, beetle car, boat car, fish car and wedge car.

Carriage, carriage era, because cars do not have their own modeling style, can also be said to be the prehistoric era of car modeling.

Box car, 1986, French Ben Hart and Rabaco produced the world's first closed car, which was also the beginning of the box car. 19 15, Ford motor company of the United States produced a car different from the horse model, which was called a "box car" because of its appearance as a big box with doors and windows.

In the late era of Beetle and Box Cars, people began to realize the importance of air resistance.

Boats and cars. 1937, the design genius Fernand Porsche began to design cars that looked like Beetles.

The boat-shaped car adopts the design method of placing the cabin between the two axles. From the appearance, the whole vehicle looks like a ship, which is called a boat-shaped vehicle. Ford V8 car produced by Ford Company 1949 is the representative of boat car.

Influential factors: After 100 years of continuous improvement and innovation, it has condensed human wisdom and intelligence, and benefited from the support of many industries such as petroleum, steel, aluminum, chemical industry, plastics, machinery and equipment, electric power, road network, electronic technology, finance, etc., which has driven their development and become various types and specifications of transportation tools, which are widely used in all fields of social and economic life.

Extended data:

The oil crisis has greatly promoted the development of automobile energy-saving technology, especially the technology of optimizing emissions. Such as: developing small cars, reducing the weight of cars, improving the transmission efficiency of cars, popularizing tubeless all-steel radial tires, improving tire patterns and reducing the wind resistance of cars.

Lean combustion of engines, electronic control of gas distribution, fuel supply and ignition and supercharging technology, diesel engines with higher thermal efficiency than gasoline engines have become the main power of commercial vehicles, and the proportion of diesel vehicles is increasing day by day; Using compressed natural gas, liquefied petroleum gas, methanol, ethanol, vegetable oil and other alternative fuels, new energy vehicles such as electric, hybrid and fuel cells have been developed.
