However, nowadays, automobiles are the main source of transportation worldwide. There are the internal combustion vehicles (gasoline powered cars), and fast growing sales and demand of hybrid electric vehicles (HEV's). Even though there are many differences as well as similarities, between these two major forms of transportation, Hybrid electric vehicles (HEV's) have increased fuel efficiency, less energy loss and are much more environmentally friendly compared to traditional vehicles.
HEV's combine the internal combustion engine of a conventional vehicle with the electric battery and motor of an electric car. …
