Automobiles are vehicles (motor cars) that run on the road. They can be two or four wheeled and have seating for one to seven people. They are primarily used for transporting passengers rather than goods.

They have many parts like a body, chassis, engine, drivetrain, control systems, safety systems and emission-control systems. They can also be fuelled with petrol, diesel or gas.

The first vehicle to use an internal combustion engine was built in 1885 by Karl Benz in Germany. He patented the Otto Cycle engine and began to sell his Motorwagen in 1888.

He also invented a battery ignition system, a spark plug, a clutch and a gear shift. He also designed a radiator for cooling the engine.

These inventions helped him to develop the world’s first automobiles. They were then produced in large numbers and sold around the world.

During the 20th century, the automobile was one of the greatest inventions that changed human life in the United States and all over the world. It gave people more personal freedom and access to jobs and services. It also made it possible for women to work in factories and other places that men traditionally worked.

The automobile also led to the development of better roads and transportation and increased the amount of money that was available to individuals and families. It also helped to bring urban amenities to rural America. It also helped to improve women’s lives and gave them the right to vote.
