An automobile is a self-propelled motor vehicle with an internal combustion engine & four wheels. It is primarily used for passenger transportation on the road.

Automobiles are a complex technical system employing many sub-systems that perform specific design functions, such as body, chassis, engines, transmission, drivetrain, control systems and emission controls. The thousands of component parts that make up the automobile have evolved over time from breakthroughs in existing technology or new technologies such as electronic computers, high-strength plastics, and new alloys of steel and nonferrous metals.

The earliest autos were steam powered, but the gasoline engine came into prominence in the 1910s. Gasoline-powered cars were able to overcome competition from steam-powered vehicles and the electric automobile.

Historically, automobiles have been a significant part of human life, especially in the developed world. They have provided access to the world’s cities and allowed people to travel for work, pleasure, and transport of goods.

In Europe and the United States, automobile production began in the early 1800s. By the end of the century, America’s automotive industry had become a world leader.

Today, automobiles are a vital part of modern society. They are an important source of transportation for people who live in urban areas and are an essential tool for businesses.

In addition to being a means of transportation, automobiles play an important role in the economic development of countries. They can be used to transport goods and passengers, and also can be employed in industrial manufacturing processes such as metal stamping, pressworking, assembling, and printing.
