The car (from the Greek itself, of Latin mob% 0lis moving) refers mainly to a motorized vehicle engine itself and intended to land transport of passengers or goods without leaving a trace. Although the term car par excellence to personenautos is used to refer, there are other types of autos, such as trucks, buses, vans, motorcycles, autos or ATVs. In Spain, Royal Decree 2822\/1998 of 23 December, that the general regulation of vehicles approves car in annex II as . . Also, in the Royal Decree is the motor vehicle as defined ë TS fitted with engine for propulsion vehicle. . A car has several wheels with tyres and capacity of at least a seat for the driver. Some wheels, normally the front (can the rear as in a dumper) directive to the sides change to rotate to allow and curves to incorporate, which by the driver via a steering wheel are driven. The car found Karl Friedrich Benz in the German city of Mannheim in 1886 from. Their models which in turn soon after other pioneers, such as Gottlieb Daimler and Wilhelm Maybach are proposed. First long on a car trip was Bertha Benz in 1888, when going from Mannheim to Pforzheim, cities by about 105 km are separated. It should be noted that it is a milestone in old car was given a car of this time had about 20 km\/h as maximum speed, a lot more fuel than spend now spent a vehicle at the same speed and the gasoline was bought in pharmacieswhere it is not available in large quantities was. In 1910, Henry Ford began producing cars in an assembly line, completely innovative system that allowed him to unthinkable production figures until then to reach. Is now investigating new ways to get faster and more efficient ë nt including better roads to move allowing to move. The old future vision of the flying car is currently rejected, would the energy needed to make them in the air are much larger. A possible future of the car is replaced by means of public transport, with greater energy efficiency. This can happen due to lack of oil and its consequent price increase. Another future line is the autonomous cars without driver. So far, have been two editions of the DARPA Grand Challenge competition, organized by the Ministry of defence of the United States, where some autonomous cars have made a trip without a driver. in the first case through the desert of Mojave and the second for a street circuit. It has begun recently to produce in the electric motor cars in the series. The autonomy of these vehicles is still limited because little stored electric charge in the batteries per unit mass, but in the future that the capacity could be improved. Pollution level depends how the electricity used and uses the sources of the raw energy is generated. It started also the commercialization of hybrid cars, which have a thermal engine and an electric motor. The latter works, if the car to slow runs, in some models with the thermal machine is turned off. The batteries are recharged with energy, which is released by an electrical generator, which is moved by the heat engine or brake the car with regenerative brakes. Another form of energy for the car is hydrogen, which is not a source of raw energy, but one vektorenergie as is necessary for its acquisition, to consume energy. The combination of hydrogen with oxygen leaves as only waste water steam. There are two methods to the of hydrogen to use one by an internal combustion engine and one fuel cells, a technology are facing currently and in development. The hydrogen is usually of the hydrocarbons through the process of improved with steam. It could be achieved by electrolysis of water, but it is rarely done because it is a process that consumes much energy. There are also experimental engines that are driven with compressed or dallenergia solar dallaria.
