Usually, an automobile is a four-wheeled vehicle designed to carry passengers. They are also used for transporting goods.
Automobiles have a powerful engine that is responsible for moving the vehicle. It can be an internal combustion engine or a gasoline engine.
In modern automobiles, thousands of components are used to create the technical system. These include engine, transmission, body, and chassis. Manufacturers employ scientists to research and develop new technologies and systems. They also improve safety systems. Unlike the early vehicles, today’s automobiles are equipped with electronic controls to meet modern safety requirements.
Automobiles are an essential part of the modern society. They are mainly used for passenger transport. The demand for cars is increasing each year. In the US, approximately 243 million cars are registered each year.
The production of automobiles increased rapidly in the United States during the first half of the twentieth century. By the early 1920s, Ford, General Motors, and Chrysler had become the “Big Three” auto manufacturers.
Today, automobiles have become a global industry. One quarter of the world’s passenger cars are made in the United States. Approximately 70 million new passenger cars are produced each year worldwide. Approximately half of these cars are made by foreign manufacturers.
In the United States, there are about seven and a half cars for every ten people. This is the same in other countries. Automobiles are popular for their convenience and ease of use. However, they can also cause pollution.
