1. Automobile Evolution
The Automobile Pioneers
Evolving from earlier experiments with steam-powered vehicles, models using the gasoline-fueled internal-combustion engine were first developed by the German engineers Karl Benz (1885) and Gottlieb Daimler (1886). U.S. leadership in automobile production began with Henry Ford 's founding (1903) of the Ford Motor Co., its production (1908) of the inexpensive Model T, and its development of assembly-line techniques.
General Motors, Ford's principal competitor, became the world's largest automobile manufacturer in the 1920s, and U.S. dominance of the field continued until the 1970s, when it was challenged by growing sales of Japanese and German cars.
Today
Concern about pollution from gasoline combustion has led to the development of cars powered by electricity from rechargeable storage batteries and by the combustion of natural gas, but such vehicles have been limited in the distance they can travel and have only been used on a small scale, largely in metropolitan areas. The development of the automobile resulted in major sociological changes and caused new economic conditions.
Economic and Health Impacts
The main economic and health impacts of the automobile over the years include:
the creation of an industry which employs a significant number of people
the creation of new technologies and industries to support and supply them
a significant monetary cost in injury and property damage
increased air and water pollution.
Future changes in automobile technology are likely to include:
increased fuel efficiency and new industries to support it
improved safety through engineering research and development (both vehicle and road)
increased sophistication of controls and instruments, many of which will contribute to safety
