An automobile, motor car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the word defines that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. However, the term automobile is far from precise, because there are many types of vehicles that do similar tasks.

There are approximately 600 million passenger cars worldwide. There is roughly one car per eleven people.  Around the world, there were about 806 million cars and light trucks on the road in 2007; they burn over 260 billion US gallons of petrol/gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China and India..

Nicolas-Joseph Cugnot is often credited with building the first self-propelled mechanical vehicle or automobile in about 1769, by adapting an existing horse-drawn vehicle. However, this claim is disputed by some who doubt Cugnot's three-wheeler ever ran or was stable. In 1801, Richard Trevithick built and demonstrated his Puffing Devil road locomotive, believed by many to be the first demonstration of a steam-powered road vehicle. It was unable to maintain sufficient steam pressure for long periods, and was of little practical use

Although several other German engineers (including Gottlieb Daimler, Wilhelm Maybach, and Siegfried Marcus) were working on the problem at about the same time, Karl Benz generally is acknowledged as the inventor of the modern automobile.

Benz's lifelong hobby brought him to a bicycle repair shop in Mannheim owned by Max rose and Friedrich Wilhelm Eblinger. In 1883, the three founded a new company producing industrial machines: Benz & Company Rheinische Gasmotoren-Fabrik, usually referred to as, Benz & Cie. quickly growing to twenty-five employees, it soon began to produce static gas engines as well.

Based on his experience with bicycles, he used similar technology when he created an automobile. It featured wire wheels with a four-stroke engine of his own design between the rear wheels, with a very advanced coil ignition and evaporative cooling rather than a radiator. Power was transmitted by means of two roller chains to the rear axle. Karl Benz finished his creation in 1885 and named it the Benz Patent Motorwagen.

Benz began to sell the vehicle in the late summer of 1888, making it the first commercially available automobile in history.

Henry Ford (July 30, 1863 – April 7, 1947) was a famous American industrialist, the founder of the Ford Motor Company, and sponsor of the development of the assembly line technique of mass production. His introduction of the Model T automobile revolutionized transportation and American industry. As owner of the Ford Motor Company, he became one of the richest and best-known people in the world. He is known with "Fordism", that is, mass production of cheap goods coupled with high wages for workers. This was a start for the car’s mass production today.

Because gasoline and diesel cars let out too much polluted gas and it led to global warming and air pollution. So scientists have tried to make a non-polluting car or eco-friendly cars using hydrogen and sun power. Due to these work, they were able to create cars using hydrogen, sun power, and electricity. But these cars are slow as like early inventions in steam cars. I think we would go the huge process all over again.
