An automobile (also motor car or simply car) is a wheeled passenger vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to seven people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods. However, the term is far from precise. As of 2002, there were 590 million passenger cars worldwide (roughly one car for every eleven people). It is important to note that automobiles come in many different shapes, forms and specifications.

History

Some sources suggest that Ferdinand Verbiest, whilst a member of a Jesuit mission in China, may have built the first steam powered car around 1672. François Isaac de Rivaz, a Swiss inventor, designed the first internal combustion engine which was fuelled by a mixture of hydrogen and oxygen and used it to develop the world's first vehicle to run on such an engine. The design was not very successful, as was the case with Samuel Brown, Samuel Morey, and Etienne Lenoir who each produced vehicles powered by clumsy internal combustion engines.

An automobile powered by a Otto gasoline engine was built in Germany by Karl Benz in 1885 and granted a patent in the following year. Although several other engineers (including Gottlieb Daimler, Wilhelm Maybach and Siegfried Marcus) were working on the problem at about the same time, Benz is generally credited with the invention of the modern automobile.

Approximately 25 of Benz's vehicles were built before 1893, when his first four-wheeler was introduced. They were powered with four-stroke engines of his own design. Emile Roger of France, already producing Benz engines under license, now added the Benz automobile to his line of products. Because France was more open to the early automobiles, more were built and sold in France through Roger than Benz sold in Germany. From 1890 to 1895 about 30 vehicles were built by Daimler and his assistant, Wilhelm Maybach, either at the Daimler works or in the Hotel Hermann, where they set up shop after falling out with their backers. Benz and Daimler seem to have been unaware of each other's early work and worked independently.

In 1890, Emile Levassor and Armand Peugeot of France began producing vehicles with Daimler engines, and so laid the foundation of the motor industry in France. The first American car with a gasoline internal combustion engine supposedly was designed in 1877 by George Baldwin Selden of Rochester, New York, who applied for a patent on an automobile in 1879. In Britain there had been several attempts to build steam cars with varying degrees of success with Thomas Rickett even attempting a production run in 1860. Santler from Malvern is recognized by the Veteran Car Club of Great Britain as having made the first petrol-powered car in the country in 1894 followed by Frederick William Lanchester in 1895 but these were both one-ofs. The first production vehicles came from the Daimler Motor Company, founded by Harry J. Lawson in 1896, and making their first cars in 1897.

In 1892 Rudolf Diesel got a patent for a "New Rational Combustion Engine" by modifying the Carnot Cycle. In 1897 he built the first Diesel Engine. In 1895, George B. Selden was granted a United States patent for a two-stroke automobile engine (U.S. Patent 549160 ). This patent did more to hinder than encourage development of autos in the United States. Steam, electric, and gasoline powered autos competed for decades, with gasoline internal combustion engines achieving dominance in the 1910s.

The large-scale, production-line manufacturing of affordable automobiles was debuted by Ransom Eli Olds at his Oldsmobile factory in 1902. This assembly line concept was then greatly expanded by Henry Ford in the 1910s. Development of automotive technology was rapid, due in part to the hundreds of small manufacturers competing to gain the world's attention. Key developments included electric ignition and the electric self-starter (both by Charles Kettering, for the Cadillac Motor Company in 1910-1911), independent suspension, and four-wheel brakes.

Although various pistonless rotary engine designs have attempted to compete with the conventional piston and crankshaft design, only
