Automobiles (also known as motor vehicles or automobiles) are wheeled vehicles that carry people and/or cargo. They are powered by internal combustion engines and are designed to run primarily on roads. They are typically built with four wheels and seat one to eight people. They can be powered by petroleum fuels like gasoline and diesel, as well as renewable energy sources such as electricity. They also feature a chassis with suspension systems, braking systems, steering systems, wheels and tires and a body. These systems work together to make a car functional and safe.
Automobile technology has changed societies in many ways, including giving people more freedom of movement and providing them with new options for where they want to live and work. The automobile also made possible a revolution in the way goods are distributed. It gave rise to industries and jobs such as manufacturing, fuel production, and retailing. It also prompted the development of better roads and transportation services, as well as leisure activities such as tourism and recreation.
The first modern cars were developed in Europe in the late 1800s, with Germany and France leading the way. Henry Ford innovated mass production techniques that greatly increased car production and established the Big Three auto companies of Ford, General Motors, and Chrysler in the 1920s. These companies helped shape American culture and influenced global markets. Today, automobile production is a worldwide industry.
