Automobiles are wheeled vehicles designed to run primarily on roads, usually with seating for one to seven people. Generally, they are propelled by an internal combustion engine that burns a volatile fuel. Today, technological advancements have made it possible to use electric power as well as gasoline and other fuels.
The automobile revolutionized American society and brought new jobs and industries. People now had access to more work locations and could travel for pleasure. They were also able to spend more time with their families and friends, especially those living in rural areas who could visit urban cities. With this freedom came the need for a variety of services, including hotels, restaurants and amusement parks. This in turn, led to increased demand for gas and car parts, which caused the development of new factories, and the assembly line was introduced as a way to make these vehicles in large numbers.
Exactly who invented the modern automobile is a matter of dispute. Some historians give credit to Gottlieb Daimler or Karl Benz, who developed gasoline powered cars that looked and worked like the ones we drive today. However, both had predecessors who worked on similar designs.
Early steam automobiles used heavy engines attached to wagons that were slow and difficult to control. These were followed by a number of improvements including lighter and faster models that allowed for better control.
In the mid-1800s, several different companies began to produce automobiles for sale. The most popular was the Model T, which Henry Ford marketed as “putting America on wheels.” Ford used mass production to make his automobiles affordable and available to all – not just the wealthy.
As technology continued to improve, automobiles got more and more luxurious with the introduction of features such as air conditioning, power windows and seatbelts. The first turn signals were added in 1939 and by the 1960s, many vehicles had built in stereos with multiple speakers and cassette players. Today’s cars are even more advanced with GPS, backup cameras and parking assist systems.
There are three main types of automobiles: front engine, rear engine and mid-engine. In front-engine vehicles, the engine is located over or ahead of the front axle. In mid-engine vehicles, the engine is in the middle of the vehicle, and in rear-engine vehicles, the engine is behind the rear axle.
Modern automobiles are complex technical systems that employ thousands of component parts. The body, chassis, engine, drivetrain and electrical systems are just some of the components that have evolved over time. New technologies such as electronic computers, high-strength plastics and novel alloys of ferrous and nonferrous metals have helped to create breakthroughs in automobile design and manufacturing. These developments have allowed vehicles to operate more efficiently, and at the same time, reduce their environmental impact. This is especially important given the rising concerns over global warming and climate change. It’s likely that the automobile will continue to evolve in ways we can’t imagine.
