Generally, an automobile is a self-propelled motor vehicle that can be driven on land. Its design is based on the internal combustion engine, which usually uses gasoline as its fuel.
An automobile is a highly technical system, made up of thousands of component parts. These include the body, chassis, and engine. Each of these components is designed to meet certain needs, including safety, durability, stability, and handling. It also requires a fuel system, such as a gasoline or diesel engine, as well as a steering and braking system.
A modern automobile is usually powered by an internal combustion engine, which uses fuel (usually gasoline), which is then refueled by an electric motor battery. The power is transmitted to the front and rear wheels via a transmission. A motor’s power is measured in horsepower.
Modern automobiles also feature airbags, seat belts, and other safety features to protect passengers and prevent accidents. New technology has helped manufacturers create more compact and reliable vehicles. These include automated safety equipment, which greatly aids human drivers.
Until the early 20th century, automobiles were powered by steam or electricity. This was not convenient to start, and their range was short. By the end of the century, the gasoline-powered automobile had overtaken the streets of Europe and the United States.
In the United States, the automobile industry recovered after World War II. In the first half of the twentieth century, Ford, General Motors, and Chrysler became the “Big Three” automakers. They introduced new manufacturing techniques that revolutionized industrial manufacturing. This helped them sell their automobiles to a wide range of consumers.
