The Basics of Cars
Written by
Cars are the main mode of transport for hundreds of millions of people all over the world. They are the workhorses of the modern economy, burning over 260 billion gallons of gasoline and diesel fuel each year. They are a marvel of engineering in their complexity and functionality, offering nimble maneuverability, great acceleration and handling, superb safety features, comfort and much more.
The word “car” comes from the Latin word cartrus, used by the Romans for a wagon they got from the Gauls, an ancient European people they conquered. The wagon carried people and goods. Karl Benz invented the first automobile around 1885, although it’s not clear why he called his creation a “motor car.” Today, the car is considered an icon of modern civilization.
Many different manufacturers design and produce cars for the world’s markets, and they come in all shapes and sizes. Some of the most famous examples are Ferrari, Porsche and Mercedes-Benz. The automobile industry also designs, develops, manufactures and sells other motor vehicles, such as trucks and buses.
A car is a four-wheeled passenger vehicle that’s powered by an engine and driven by the wheels. It can carry a small number of passengers and have a trunk for carrying luggage.
It has a steering wheel, which controls the direction of travel and a dashboard that displays information about the vehicle’s operation. A battery powers the car’s electrical systems. The brakes slow the car by applying pressure to a drum or disc inside each wheel. The suspension system supports the weight of the car and gives it a smooth ride. The wheels and axles are attached to the suspension by springs. The drive wheels, which provide the power to move the car, are in front or in the back.
The engine produces electricity by turning a crankshaft that propels the axles and drives the wheels. Modern engines use electronic control units and computer sensors to maximize performance, and they can operate on various types of fuel, from gasoline to liquefied petroleum gas (LPG) and natural gas.
There are many benefits to owning a car, including independence and freedom. People who rely on public transport often face problems such as missing their bus stop, waiting for a long time to board and overcrowded buses. A car can also save a lot of time when you need to go to the store or to the vet.
The downside of owning a car is that it emits carbon dioxide, a greenhouse gas, when it burns fossil fuels. The good news is that you can help limit greenhouse emissions by driving less, keeping your car in good condition and using alternative fuels. You can even get a hybrid or electric car to reduce your environmental footprint. The automotive industry is constantly developing new cars that are safer, more efficient and comfortable. However, there are many factors to consider when choosing a car for you and your family. Check out our alphabetical glossary of car specification terms to help you make an informed decision.
