A hybrid electric vehicle (HEV) is a vehicle using an on-board rechargeable energy storage system (RESS) and a fueled power source for vehicle propulsion. The different propulsion power systems may have common subsystems or components.
A hybrid vehicle provides better fuel economy than a conventional vehicle, because the engine is smaller and may be run at various speeds, providing more efficiency. Other techniques may be used to recover or reduce waste energy (such as regenerative braking and shutting down the combustion engine).
The term hybrid when used in relation with cars also has other uses. Before its modern meaning of hybrid propulsion, it was used in the United States to mean a vehicle of mixed national origin, generally a European car fitted with American mechanical components; this meaning has fallen out of use. In the import scene, hybrid often described an engine swap. Some have also called flexible-fuel vehicles hybrids, because they can use a mixture of different fuels—typically gasoline and ethanol (ethyl alcohol) fuel.

A hybrid vehicle (HV) is a vehicle that uses two or more distinct power or fuel sources such as:
An on-board rechargeable energy storage system (RESS) and a fueled power source for vehicle propulsion
Human or sail powered bicycle with battery assist
A sail boat with electric power[1]
The term most commonly refers to Hybrid-electric vehicle (HEV) which includes internal combustion engines and electric motors (generally powered by electric batteries or other rechargeable energy storage system -RESS-). See also "Hybrid Vehicle Drivetrains" and "List of hybrid vehicles".

A hybrid vehicle is similar in concept to hybrid corn. With hybrid corn, two different types of corn are cross-pollinated, resulting in a better, tastier, type of corn. This is often referred to as "hybrid vigor". The seed from hybrid corn plants, however, won't produce hybrid corn. Why? It's a genetics thing.
So, a hybrid vehicle is a cross between..... what and what?
Glad you asked.
The internal combustion part comes from, are you ready? A guy in Detroit who suffers from spontaneous combustion. That's right, he occasionally starts smoldering...
The electric part comes from a lady in Fargo, North (or is it South) Dakota, who is known as the Cuisinart Queen. She can make just about anything in a Cuisinart.
Anyway, the guy from Detroit got together with the lady from Fargo (play the theme song from The Brady Bunch here) and they produced a hybrid vehicle. Granted, it only worked in the kitchen at first, and resulted in the instantaneous cooking of vegetables while being chopped. But industrious engineers refined the process and, VOILA, today we have hybrid vehicles capable of being driven down the road. Sadly, though, you can no longer prepare a 5-minute dinner in them. Such is progress....

"hybrid" referes to a vehicle that has both electric and internal combustion power.
Modern hybrids have a transmission that allows the internal combustion engine to provide power mechanicly to the drive train... or to run a generator... or both. They also have an electric motor (could be the same "machine" as the generator)
Also, nmodern hybrids have a system that actuates generators on the wheels before the friction brakes start to work. This "regenerative braking" converts the kinetic energy of the car into power stored in the batteries to be used to reaccellerate. (appx 50% of the energy is wasted as heat... but its better than not trying)

A Hybrid uses two or more types of propulsion.
The ones today use Internal Combustion Engines and Electric Motors powered by rechargeable batteries.

Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline.
Hybrid engines are built smaller to accommodate the 99% of time when not going up hill or accelerating quickly. They use the battery to provide extra acceleration power when needed.
When the car is stopped, hybrid gasoline motors can shut off and run off their electric motor and battery.
Hybrid cars are often lighter and more aerodynamic; tires are often stiffer and inflated higher to reduce drag.
Hybrid cars often recover braking energy and use it to charge the battery.

Hybrids are electric powered autos yet electric powered autos are actually not inevitably hybrids. The be conscious hybrid ability that's a hybrid between an electric powered automobile and a time-honored automobile so this is the two and has 2 force practice platforms.

A vehicle that uses fuel and passively generated electricity to propel it. It is theoretically a better option but the cars are far from being family friendly and the batteries are a huge fire hazard in the event of an accident. The concept is good I am just not sure it is the best we can do.

One that uses electric batteries + gas to power it, so you can use one or the other, depending on the conditions. A Hybrid anything is a combination of things working in conjunction with each other to achieve the same thing.
