Automobiles are vehicles that use an internal combustion engine (called a motor) to make them move. They usually have four wheels and seats for passengers. Most burn a fuel, such as gasoline or diesel, to turn the motor. The motor turns the wheels through a transmission system that can speed up or slow down the vehicle.

The first automobiles were steam and electric powered. They were expensive and had many problems. Karl Benz invented the gas powered automobile in 1885/1886. The Benz Motorwagen was successful and popular. Bertha Benz drove her husband’s car over long distances to promote it.

Today’s cars are made of thousands of individual parts that work together like the human body. They have circulatory systems for coolant and lubrication fluid. They have systems that detect and warn the driver of problems.

Automakers create a wide variety of car styles and sizes for different needs. There are sports cars with sleek lines and fast engines, family vehicles such as minivans and SUVs, and trucks with utility and towing capabilities. There are also hybrid, electrical, and autonomous cars on the horizon.

Having your own automobile is a convenience that allows you to have more personal freedom. It lets you go to places you might not be able to reach on foot or with public transportation. It gives you the opportunity to shop, visit friends and relatives, and take road trips. With a good car, you can do all these things safely and comfortably.
