Automobiles are four-wheeled vehicles, usually for passenger transportation and often propelled by an internal combustion engine using a volatile fuel. These engines typically run on petrol (gasoline), diesel or other liquid petroleum gas, but may also use other fuels such as liquefied natural gas and biofuels. Various types of transmissions are used to transfer power from the engine to the driving wheels. There are many different styles of automobiles and the industry is highly competitive. Various automobiles serve different purposes such as police cars, fire trucks, emergency ambulances and cargo transporters.
THE AUTOMOBILE OPENED UP OUR WORLD
The automobile revolutionized American society and created many new industries. It gave people more personal freedom, as they no longer had to depend on others for transportation or schedule their lives around bus and train schedules. It allowed for larger social circles, because friends could visit each other more easily, and opened up opportunities for work and residence, because people could move more freely between jobs and places.
In the United States in particular, automobiles were a significant source of employment and wealth. Automobile production was also a major contributor to the nation’s war effort in both World Wars. After the war, the automobile industry shifted its focus to marketing and profits. Engineering was subordinated to questionable aesthetics and nonfunctional styling, and quality deteriorated. By the end of the 20th century, American manufacturers were squeezing out higher unit profits from gasoline-guzzling “road cruisers” at the expense of their customers’ health and safety.
There are many reasons why an automobile is necessary in a modern world. They can carry large amounts of goods, speed up travel time and take people to far away places that are not accessible by other means. They can also be used to deliver medical supplies, groceries and food for distant areas. There are also special automobiles made for certain situations, like crane vehicles at construction sites and road rollers at roads.
Throughout history, there have been several important people who have contributed to the development of automobiles. Probably the most influential was Henry Ford, who invented the assembly line and Model T, making automobiles affordable to the average American family.
Today, automobiles continue to play an important role in the global economy. Every year over 5 – 59 million cars are produced worldwide and the majority of them are powered by gasoline. Automobiles consume a considerable amount of fossil fuels, which must be extracted from the Earth’s crust. This creates environmental problems such as air pollution and drains dwindling world oil reserves. There are also concerns that the use of automobiles will eventually reduce the supply of oil, which is a vital resource to humanity. Nevertheless, most experts believe that automobiles are here to stay. The most important thing is to minimize their environmental impact and find alternative methods for transporting goods and people. The most practical solution is to find new ways of utilizing the surplus of fossil fuels on the planet, which can help protect our environment and make a better future for mankind.
