Theory and Design of Automotive Engine

advertisement 

Automobiles through the Years - Since they originated in the late 1800s, automobiles have changed and developed in response to consumer wishes, economic conditions, and advancing technology. The first gas-powered vehicles looked like horse buggies with engines mounted underneath because this was the style to which people were accustomed. By 1910, however, features like the front mounted engine were already established, giving the automobile a look that was all its own.

As public demand for cars increased, the vehicles became more stylized. The classic cars of the 1920s and 1930s epitomize the sleek, individually designed luxury cars called the “classic cars.” During the 1940s and 1950s, automobiles generally became larger until the advent of the “compact” car, which immediately became a popular alternative. The gasoline crisis is reflected in the fuel efficient cars made in the 1970s and 1980s. Current designs continue to reflect economy awareness, although many different markets exist.
