An automobile is a vehicle used for transporting passengers. It has four wheels and is powered by an internal combustion engine or electric motor. The engine is usually fueled by gasoline (petrol), but some have been powered by alcohol, naphtha, or other fuels. Automobiles are the most common form of transportation in most countries. They are generally safe and convenient, and can be driven by a single person. In addition to allowing people to travel quickly and efficiently, they also symbolize a sense of individual freedom. This is particularly true in the United States, where the automobile has become a status symbol and a sign of wealth.

The scientific and technological building blocks of the modern automobile go back several hundred years. In the late 1600s, Christiaan Huygens invented a type of internal combustion engine sparked by gunpowder. By 1900, manufacturers such as Ransom Olds and William Packard were producing automobiles commercially. In the United States, its vast land area and a large population encouraged high demand for automotive transportation. The absence of tariff barriers also encouraged automobile sales over a wide geographic area. Cheap raw materials and the American manufacturing tradition also encouraged mechanization of production processes.

In the 1920s, Alfred P. Sloan introduced a new way of managing the production and marketing of cars, the assembly line. This allowed a manufacturer to produce cars in large numbers at low cost. This strategy led to the growth of the automobile industry and made it possible for middle-class families to own their own car. It also enabled the American culture to embrace the automobile as a symbol of individual freedom.

Automobiles have become the most popular form of transportation in the world, with 1.4 billion in operation worldwide as of 2018. They are primarily used to commute to work and other daily activities. They can also be used for leisure, such as taking a vacation or going shopping. Automobiles can be found in rural areas as well as urban centers. The use of automobiles has transformed the world and changed the ways we live, work, play, and socialize.
