Automotive production down the ages has required a wide range of energy-conversion systems. These include electric, steam, solar, turbine, rotary, and different types of piston-type internal combustion engines. The reciprocating-piston internal -combustion system, operating on a four-stroke cycle, has been the most successful for automobiles, while diesel engines are widely used for trucks and buses.
The gasoline engine was originally selected for the automobile due to its flexibility over a wide range of speeds. Also, the power developed for a given weight engine was reasonable; it could be produced by economical mass-production methods; and it used a readily available, moderately priced fuel--gasoline. Reliability, compact size, and range of operation later became important factors.
In today’s world, there has been a growing emphasis on the pollution producing features of automotive power systems. This has created new interest in alternate power sources and internal-combustion engine refinements that were not economically feasible in prior years. Although a few limited-production battery-powered electric vehicles have appeared from time to time, they have not proved to be competitive owing to costs and operating characteristics. However, the gasoline engine, with its new emission-control devices to improve emission performance, has not yet been challenged significantly.

- Let the time of life be tuff and the roads be rough. Deep in my heart there lives a hope that my spring will surely come. Deep in my eyes I have a dream , I know my sun will sure shine. Let him give me grives and pain to take me in his arms forever. I know my prime will surely come. Let my eyes be filled with tears and the sight of my dream be unclear.. When I would take the world in my stride.

Car Models in India
In earlier days there were a few car models available in India. Ambassador and Fiat were the only two models that were manufactured in India and rest of the models had to imported. In 1980s Government of India launched Maruti in collaboration with Suzuki of Japan. Maruti revolutionized Indian car industry in a big way. But the main push for Indian automobile industrycame after 1991 in the post liberalization era. Industrial guidelines and investment climate was made more investor friendly. This prompted all the big automobile players such as Hyundai, Mitsubishi, General Motors, Honda, Mercedes et al. to invest in India and today most of the car models that are available elsewhere are also available in India.
