Hybrid electric vehicles (HEV) use two or more energy conversion technologies. This is usually a combination of a conventional engine with extra batteries driving electric motors.
Hybrid electric vehicles (HEV) use “two or more energy conversion technologies.” Often, this means coupling an internal combustion engine (ICE) with a secondary source of stored electrical power such as batteries. The different power sources are then used separately or in tandem to deliver an optimum combination of power and fuel economy. The objective that has led to the development of hybrid vehicles involves delivering every greater fuel economies as the amount of allowable harmful emissions trends towards zero.
There are a number of different types of hybrid vehicle that have been released onto the market. Here is a sample of some of those HEV types. Not all of these models will have been made available outside of the United States, and those that have been released may be known by a different name in other regions.
