Automobiles are a form of land transportation that uses wheels to propel it forward, & is powered by an internal combustion engine. They are a type of complex machinery, so manufacturers must pay attention to their design, production & operation. An automobile’s components & systems include the body, chassis & power-generating & transmission units. The latter are affixed to the frame, which is supported by springs & shock absorbers that allow it to withstand bumps on the road.
The modern automobile has become an essential part of our lives; many aspects of modern life would be inconceivable without it. Entire societies have been restructured around the freedom of movement that automobiles provide, while problems such as traffic congestion & pollution have evolved in response to their use.
Research & development have been central to the growth of the automotive industry, which has made a significant contribution to scientific progress. New models are constantly being produced that improve on the performance, comfort & safety of existing vehicles. This is largely due to the efforts of auto engineers, who work on the design & testing of automobiles.
The arrangement & choice of an automobile’s components vary depending on the intended use. For example, a car built for fuel efficiency may be designed with a smaller engine & front-wheel drive, while a sports model built for high speeds will have more powerful engines & four-wheel drive. The design of automobiles has also been greatly improved by the application of computer technology.
