What Are Automobiles?


Automobiles are a type of passenger vehicle that use an internal combustion engine fueled most often by gasoline, a liquid petroleum product. Also known as a car, the automobile is one of the most universal of modern technologies and is produced by one of the world’s largest industries. There are many different types of automobiles available, including sports cars, SUVs and vans. Some even have a retractable roof for an open-air drive.

Modern automobiles are complex technical systems with thousands of subsystems that have specific design functions. These subsystems include the body, chassis, engine, transmission, and control systems. Many of these components have evolved from breakthroughs in existing technology. Others have resulted from environmental and safety legislation, competition among manufacturers and the development of high-strength metal alloys and plastics.


Automobile technology dates back several hundred years, when Dutch scientist Christiaan Huygens invented a type of internal combustion engine sparked by gunpowder in the late 1600s. By 1900, the first automobiles were appearing on the streets and highways of Europe and the United States. Early automobiles were powered by steam, batteries and gas, with a gasoline engine winning the competition.

The automobile was a major innovation that opened up the world in ways never before possible. It changed industry, agriculture and everyday life. Cities grew, roads were built and new businesses developed to supply automobile parts and fuel. In addition, the invention of the assembly line reduced the price of the car and allowed more people to own them.

Today, there are more than 1.4 billion cars in operation worldwide. Most of them are gasoline-powered, although some run on electric power or hydrogen. In the United States alone, people travel more than three trillion miles (five trillion kilometers) every year.


Automobiles give you the freedom to go where you want, when you want, without having to depend on anyone else. Whether you are running errands, going to work or visiting friends and family, an automobile gives you the convenience of traveling at your own pace. This can save you time and money when compared to using public transportation, such as buses, trains and taxis.

SAFETY: Having your own car means that you can take trips with friends and family, without having to worry about finding a ride or being a designated driver. You can also feel safe while driving if you obey the rules of the road and avoid reckless drivers.

EFFICIENCY: Having your own automobile can help you save on costs, such as food and fuel. You can also reach your destination in a shorter amount of time. This can also help you get to work on time and not be late for important meetings.

Having your own car can also provide you with more career opportunities, since you can travel farther distances to meet clients. It can also help you build stronger relationships with your coworkers. It can be a great way to spend more time with your family, as you can go on long road trips together.
