Car
A car (also called an automobile) is a machine used for travel (a
vehicle). Cars are different from motorcycles, and bicycles because they have four wheels.
Structure
A car has an engine to move it, put together with three or more wheels (almost always four), a purpose-built body frame, and controls such as a steering wheel and brakes. They usually have a seat for the driver and at least one other seat for a passenger, and most have a total of 4 to 8. Some small "city" cars carry only two people, and/or have very little luggage space; other types are able to carry many passengers or heavy loads. For example, family station wagons carry from 6 to 9 people, or fewer people with lots of luggage. A van or pickup truck is a car-like vehicle made for carrying medium sized loads, for example of goods for delivery or plumber's and builder's tools and materials.
In order for a car to work, it must have fuel, most often petrol, which is sometimes called gasoline, or can run on diesel. Other less common fuels are natural gas, or electricity. Many car-making companies are also now trying to build vehicles that run successfully using hydrogen fuel cells, which are as convenient as petrol or diesel fuelled cars but do not give out any polluting exhaust gases (but making hydrogen may at first still need electricity made by a powerplant that burns similar fossil fuels).
