Few inventions in modern times have been as profoundly and pervasively influential in the lives of humans and the global environment as the automobile. It has transformed cities, restructured entire economies, and spawned a vast industry of repair and accessories. But it also encourages sprawl, degrades landscapes, produces pollution and traffic congestion, and has sparked an arms race between manufacturers that has driven up prices and created a huge consumer market for automobiles.
An automobile is a self-propelled vehicle for passenger transportation that is commonly powered by an internal combustion engine that uses a volatile fuel. Its design and development is the subject of a branch of engineering known as automotive engineering. The modern automobile is a complex technical system consisting of thousands of subsystems that have specific design functions. These include the body, chassis, engine, drivetrain, and control systems.
The arrangement and choice of automobile components depends on the vehicle’s intended use. For example, a car designed for off-road driving must have durable and simple systems that can withstand severe overloads and extreme operating conditions. On the other hand, a high-speed sports car must have an optimized suspension and engine performance to support fast, safe driving.
Automobiles require a number of different systems to function properly, including cooling systems for the engine, radiator, and braking fluid; a circulatory system for oil; an electrical system for starting and recharging the battery; and a computer system that governs many of its processes. Many of these systems are modeled on the human body’s systems, and they all work together to make a car run smoothly.
Most modern automobiles have four to eight wheels and are powered by engines that use gasoline or other fuel. They are regulated by the government to meet emissions standards. Most automobiles are made in the United States and sold throughout the world.
Almost everyone owns an automobile today, and modern life seems inconceivable without them. An automobile allows you to travel anywhere in comfort and speed, and it gives you the freedom to choose when and where to go. You can go shopping, visit friends, and take family vacations. You can even attend concerts and picnics in your own car.
An automobile is also a status symbol, and it may be a major part of your image. It may be a symbol of your wealth or social standing, and it can affect your job opportunities. Some employers look at a potential employee’s license and car as important criteria for the job.
Whether you are looking for a sporty car, a family sedan, or an SUV, there is a model that will suit your needs and budget. But no matter what you choose, the basic principles of good driving are the same. Keep your eyes on the road, keep your hands on the wheel, and stay cool. Then you’ll be ready for your next adventure.
