Automotive Hybrid Technology

A hybrid vehicle uses two or more distinct types of power, such as internal combustion engine to drive an electric generator that powers an electric motor,[1] e.g. in diesel-electric trains using diesel engines to drive an electric generator that powers an electric motor, and submarines that use diesels when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids.

The basic principle with hybrid vehicles is that the different power sources work better at different speeds and then switching from one to the other at the proper time during the speed transform yields a win-win in terms of energy efficiency, as such that translates into greater fuel efficiency
