AUTOMOBILE HISTORY
The history of the automobile begins in early 1769, with the creation of steam-powered automobiles capable of human transport. In 1806, the first cars powered by internal combustion engines running on fuel gas appeared, which led to the introduction in 1885 of the ubiquitous modern gasoline – or petrol-fueled internal combustion engine. Cars powered by electricity briefly appeared at the turn of the 20th century but largely disappeared from commonality until the turn of the 21st century, when interest in low and zero-emissions transportation was reignited. As such, the early history of the automobile can be divided into a number of eras based on the prevalent method of automotive propulsion during that time. Later periods were defined by trends in exterior styling and size and utility preferences.
STEAM AUTOMOBILES
Steam-powered self-propelled vehicles are thought to have been devised in the late-18th century. Nicolas-Joseph Cugnot demonstrated his fardier à vapeur, an experimental steam-driven artillery tractor, in 1770 and 1771. Cugnot's design proved to be impractical and his invention was not developed in his native France, the centre of innovation passing to Great Britain. By 1784, William Murdoch had built a working model of a steam carriage in Redruth, and in 1801 Richard Trevithick was running a full-sized vehicle on the road in Camborne. Such vehicles were in vogue for a time, and over the next decades such innovations as hand brakes, multi-speed transmissions, and better steering developed. Some were commercially successful in providing mass transit, until a backlash against these large speedy vehicles resulted in passing a law, the Locomotive Act, in 1865 requiring self-propelled vehicles on public roads in the United Kingdom be preceded by a man on foot waving a red flag and blowing a horn. This effectively killed road auto development in the UK for most of the rest of the 19th century as inventors and engineers shifted their efforts to improvements in railway locomotives. The law was not repealed until 1896, although the need for the red flag was removed in 1878.
