Automobiles are vehicles that are powered by an engine, and they use a system of gears to transfer power from the engine to the wheels. The vast majority of automobiles run on gasoline, although some are diesel or electric powered. The advantages of automobiles include their convenience, speed, and ability to carry passengers and luggage. They are also safer than walking or riding bicycles for long distances, and they allow individuals to maintain a schedule without having to depend on other people for transportation. Automobiles have also played a major role in shaping American culture and society, from the Model T Fords that rolled off the assembly line in the early 1900s to the artful mid-century modern designs that cruised U.S. highways and byways in the 1950s.
The development of the automobile was a critical factor in America’s transition from a rural to an industrial economy. As the industry grew to become one of the nation’s most important manufacturing sectors, it transformed family life and social mores. Families who owned cars could spend more time together as they traveled to work, shopping, and other activities. They could live in suburban neighborhoods with amenities like swimming pools and playgrounds, and they could enjoy leisure activities such as dining out or going to movies.
The automotive industry was revolutionized by the development of mass production techniques, first introduced by Henry Ford with his Model T. The process allowed manufacturers to produce automobiles at a lower price, making them affordable to middle-class Americans. By the 1920s, Ford, General Motors, and Chrysler had dominated the market, and the industry was in the midst of a consolidation phase.
An automobile can be used for personal transportation, or it may be employed for commercial purposes such as hauling freight. Its engines can be powered by petroleum, natural gas, electricity, or hydrogen produced from methane or other fossil fuels. The internal combustion of these fuels releases carbon dioxide, a greenhouse gas, into the atmosphere. Several ways to limit greenhouse emissions from automobiles include using a hybrid, driving less, or purchasing a car that uses alternative fuels.
