An automobile, motor car or car is a wheeled A wheel is a circular device that is capable of rotating on its axis, facilitating movement or transportation while supporting a load , or performing labour in machines. Common examples are found in transport applications. A wheel, together with an axle overcomes friction by facilitating motion by rolling. In order for wheels to rotate, a moment motor vehicle A motor vehicle is a wheeled vehicle whose propulsion is provided by an engine or motor . The internal combustion engine is the most common motor choice, although electric motors or other types are sometimes used. Motor vehicles or road vehicles typically run on public roads. The rules of the road are laws or practices which all road users must used for transporting Transport or transportation is the movement of people and goods from one location to another. Transport is performed by modes, such as air, rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles, and operations passengers Crew members , as well as the driver or pilot of the vehicle, are usually not considered to be passengers. For example, a flight attendant on an airline would not be considered a "passenger" while on duty, but an employee riding in a company car being driven by another person would be considered a passenger, even if the car was being, which also carries its own engine The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, which are produced by the combustion, directly applies force to a movable component of the engine, such as the or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport Transport or transportation is the movement of people and goods from one location to another. Transport is performed by modes, such as air, rail, road, water, cable, pipeline and space. The field can be divided into infrastructure, vehicles, and operations of people rather than goods.[1] However, the term automobile is far from precise, because there are many types of vehicles that do similar tasks.
There are approximately 600 million passenger cars worldwide (roughly one car per eleven people).[2][3] Around the world, there were about 806 million cars and light trucks on the road in 2007; they burn over 1 billion m³ (260 billion US gallons) of gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China As of November 2009, China is the largest auto market in the world. China's automobile industry has been in rapid development since the early 1990s. In 2009, China produced 13.79 million passenger cars. Of these, 44% are local brands , the rest being produced by joint ventures with foreign car makers such as Volkswagen, General Motors, Hyundai, and India The automobile industry in India is the ninth largest in the world with an annual production of over 2.3 million units in 2008. In 2009, India emerged as Asia's fourth largest exporter of automobiles, behind Japan, South Korea and Thailand.[4]
