Structure

A car has an engine to power it, put together with three or more wheels (normally 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 or estate cars 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 ).
History

The earliest automobiles recorded were actually steam engines attached to wagons. This was invented by Nicolas-Joseph Cugnot in the late 1700's. The steam engines were heavy and therefore the wagon was very slow and hard to control. Cugnot was the very first person to get into a motor vehicle accident when he crashed his wagon into a wall!

Also, there were in the 1830's that were powered by electricity, but these were also very slow and heavy so they were eventually left behind.
