In 1769, Brezine invented the first self-powered vehicle. There came many modifications in the mechanism of hybrid cars as time passed. The modern automobiles are meeting the current demands, or requirements of the global world, and they are in tenure of latest technology.

Two or more unique power sources are used in a hybrid vehicle to move it. Hybrid electric vehicles (HEVs) refer a term that combine an internal combustion engine, and one, or more electric motors.

It is more important to know that hybrid cars have the strong power functions like on-board or out-board rechargeable energy storage system (RESS), Gasoline or Diesel fuel Hydrogen, Compressed air Liquid nitrogen, Human powered e.g. pedalling or rowing Wind electricity, compressed or liquefied natural gas, and Solar Waste heat from internal combustion engine. This could be converted to steam or electricity (e.g. via Sterling engine or Thermo generator) to increase vehicle propulsion. The extra power may also be used for supplemental systems (for example cooling for cool-trucks,) Coal, wood, biochar and others solid combustibles electromagnetic fields. The hybrid vehicle originally contains huge fuel economy and fewer emissions than conventional internal combustion engine vehicles (ICEVs), which reduce emissions being generated. These savings are basically achieved by three elements of a typical hybrid design: 1. Hybrid cars rely on both the engine and the electric motors for greater power needs, resulting in a little engine sized more for normal usage rather than peak power usage. A smaller engine can give less internal losses and lower weight. 2. Hybrid cars are having unique battery storage capacity to store and reuse recaptured energy, commonly in stop-and-go traffic.

Originally, hybrid cars have huge fuel economy, and fewer emissions than the conventional internal combustion engine vehicles, which cuts short the emissions being generated.

These are some vital features that make a hybrid car particularly efficient for city traffic, where people find frequent stops, coasting and waste periods.

In addition, noise emissions are decreased specifically at idling and low operating speeds, in comparison to conventional engine vehicles. At continuous high speed highway, these features are less useful in reducing emissions.

When we talk about the term hybrid vehicle, it clearly refers to a hybrid electric vehicle.

These vital features of a hybrid car make it extraordinary; particularly it is efficient for city traffic, where people find frequent stops, coasting, and waste periods. At idling and low operating speeds, noise emissions are specifically decreased in comparison to conventional engine vehicles.

Such important features of this car make hybrid car particularly useful for city traffic where people may find frequent stops, coasting, and waste periods. If compared to the conventional cars, noise emissions in hybrid cars are decreased specifically at idling, and low operating speed. These features are less useful in reducing emissions at continuous high-speed highway.

The new upcoming 2010 model of hybrids cars is the Lexus RX450h. The production of Lexus RX450h model changed the view of the people, which they always think that hybrid cars are compact cars. Lexus has classified it as a luxury SUV, and this hybrid car is one of the primary SUV hybrids. The technological advancement continues despite of the reality that the fuel is going lesser day-by-day. Thus, the cars of the future are hybrid cars. The popularity and demand of hybrid cars is wonderfully increasing.
