Automobiles are motor vehicles that are powered by internal combustion engines, most commonly fueled by gasoline. The automobile is one of the most universal of modern technologies, and it remains a popular mode of transportation worldwide. It has been adapted for many different purposes, including transporting people, hauling cargo, and serving as a mobile home. The automotive industry is a major global employer and is responsible for the production of over 73 million vehicles per year.

The four essential components of an automobile are chassis, engine, drive system and controls. Apart from these, there are auxiliaries as well that make the driving experience more comfortable for the driver. Examples of such auxiliaries include indicators (to indicate the turning direction of the vehicle), air-conditioner and many others.

The first major step toward a more modern society came in the early 20th century, when automobiles became affordable for middle-class families. The revolution continued as companies like Ford introduced assembly line techniques that made car manufacturing cheaper and faster, allowing more and more Americans to own their own cars. Today, it’s almost impossible to imagine life without a car. Whether it’s running errands or going on weekend road trips, a car lets you travel anywhere at any time. In addition, owning a car can help you build credit and show potential lenders that you’re reliable. It can also help you get a mortgage or loan for other major purchases. It can even make it easier to get jobs in other cities or visit family and friends in remote locations.
