Automobiles (or motor cars) are usually four-wheeled vehicles that are propelled by an internal combustion engine, which is powered by a volatile fuel such as gasoline, diesel or kerosene. They can be very useful for carrying passengers and cargo, especially when public transport is not good enough to get you where you need to go quickly or conveniently.
Vehicles are made from various materials and can be designed for different purposes. Examples include passenger and commercial vehicles, trucks, buses and motorcycles.
Automotives are an extremely complex technical system, employing thousands of subsystems with specific design functions. Some of these are body, chassis, engine, drivetrain, control systems, emission-control systems, safety systems, and braking systems.
The automobile is a significant technological advancement over its predecessors, and it has revolutionized the world of transportation. It has been a vital force in the development of society, enabling people to travel more freely and economically.
In addition, automobiles have helped to develop a wide variety of new industries. For example, the industry became a major source of military vehicles and war materiel during the First World War.
Automobiles can also help to speed up your travel when traffic congestion is a problem. But they can also cause air pollution if many people use them in a small area.
The automobile industry has been dominated by American firms in recent decades, but the first automobiles were invented and perfected in Germany and France. Henry Ford introduced modern mass production techniques that became standard in the twentieth century. These techniques paved the way for the American automobile industry to become a global enterprise.
