An automobile is a vehicle that is self-propelled and can travel on land. It is usually four wheels and powered by an internal combustion engine that uses a volatile fuel for power. Automobiles can be classified into different categories according to their use.
Passenger Vehicles
Cars, buses and taxis are the most common type of passenger vehicles. They are designed to carry one to eight occupants.
Commercial Vehicles
Trucks, tempos and containers are also common types of commercial vehicles.
Special purpose vehicles are those used for a particular task, such as ambulances, fire brigades, police cars, and ships’ deckhands.
These vehicles may be powered by an internal combustion engine or by electric motors or other alternative energy sources.
The first automobiles were invented in the late 18th century. Early cars were designed to run on horsepower or steam. However, it was only after the development of the internal combustion engine that cars became feasible for mass production.
In 1886, German engineer Carl Benz patented a type of internal combustion engine that was able to produce enough power to drive a vehicle without the need for human assistance. This invention laid the foundation for the modern automotive industry.
It was a technological breakthrough that sparked competition between manufacturers, allowing them to reduce costs and offer higher-quality products at lower prices. The resulting cars were cheaper, easier to build, and more comfortable for the driver.
They were also safer to drive, with better visibility and fewer accidents.
As a result, the automotive industry grew rapidly, and it now accounts for more than half of all global vehicle sales.
Some of the most popular styles of car include the sedan, the hatchback and the station wagon. They are available in a variety of sizes to suit the needs of individual consumers.
Most cars are designed to carry multiple occupants, often with four or five seats. They can also be configured to accommodate luggage or cargo.
These vehicles are primarily used to transport passengers, but they can also be used for hauling goods.
They are commonly propelled by an internal combustion engine that runs on a fuel, such as gasoline, diesel or CNG. Increasingly, they are also propelled by an electric motor or an electrical generator.
The body of an automobile is made of steel, aluminium or plastics. It is shaped and assembled after the chassis is received from the manufacturer.
It is important that the body of a car be sturdy and durable, as it will need to be exposed to various weather conditions, road debris and other hazards. It must also have a good load-carrying capacity and be easy to operate for both drivers and passengers.
Depending on the end-use of the product, it must be designed for either high speed road systems or off-road use. Stability depends on the distribution of weight between the front and rear wheels, the height of the centre of gravity and its position relative to the aerodynamic centre of pressure of the vehicle, suspension characteristics, and the selection of which wheels are used for propulsion.
