Automobiles are self-propelled vehicles that are used to transport passengers and goods. They are usually four-wheeled and are powered by an internal combustion engine or an electric motor.
The automobile is a complex technical system that consists of thousands of parts. Like the human circulatory system, the modern auto mobile has semi-independent systems for fuel, lubricating oil, coolant fluid, and brake fluid.
They also have engines with cylinders and pistons that range in power from less than fifty horsepower to over two hundred horsepower. They use a variety of different fuels, including gasoline, diesel, and electricity.
People often own automobiles to help them travel faster and easier. They can be used for both business and pleasure, and they give people the freedom to go where they want. They can also be a great investment.
