There are many definitions of the car. Some said steam-powered coaches are cars and others, like Daimler-Benz (makers of Mercedes Benz) say that cars are light carriages for private transportation with three or four wheels, powered by a liquid-fueled internal combustion engine. Depending on your definition of a car, the automobile could have been invented by any number of people at any number of dates.

The first data of a self-propelled vehicle came from Leonardo da Vinciwho toyed with the idea in the 15th century. He planned and drew some models in his notes, but he didn't actually assemble a car. The steam engine was considered to be first built by James Watt in 1765 and was perfected by both English and French engineers over the next century.

Nicolas-Joseph Cugnot, William Murdoch and Richard Trevithick all have invented steam-powered monsters that are so gigantic and heavy that they needed a completely flat surface to move on. In reality, iron rails were installed on roads in Paris and London for the next 120 years just to accommodate the automobiles, which were basically smaller versions of trains.

Cars designed during the Steam Era were unusual and fantastically bizarre. In the United States, Oliver Evans invented an amphibious vehicle that can journey on wheels and on water with the help of a paddle wheel. Ivan Kulibin of Russia designed a car with modern day features such as flywheels, brakes and a gear box. Oddly enough, it was it was human-pedalled. Etience Lenoir invented something he called a hippo mobile that proved to the people that automobiles can operate on long trips. He drove all the way from Paris to Jonville Le-Pont.

Karl Benz was one of the first to mass-produce cars. His cars appealed to many due to being able to move at 45 km/h (28.2 mph). In France, Panhard et Levassan was the first ever company to be formed exclusively for the sole idea of making cars. The Duryea brothers (Frank and Charles) were the first automobile manufacturers in the United States, and they were quickly followed by Ford and Winton.

A special mention should be said about Henry Ford. Opposingly to admired belief, he didn't actually built cars. He perfected the structure of manufacturing cars, by making improvements to the production line. He used one worker for one task and had an ingenious system of dropping the car's body on its wheels. He also added modern features such as the car radio after receiving the idea from private jets.

There were different eras to the automobile's history. And each brought different improvements to the car. In the Vintage Era, internal combustion engines and the overhead cam engines were adapted. A prime example of this is the Austin 7. During the Pre-War Era, fully-closed models were produced for the first time and trunks were added. The post War Era gave birth to cars which have more resemblance to current automobiles. Creative and shiny cars, like the Mini Cooper, have left a memorable stamp on automobile history.

Whether you're driving a luxury car, a sedan or a piece of junk that can hardly be called a car, it's a good feeling to know how far the car has evolved from being steam-powered coaches to advanced practical vehicles.
