They were invented as a result of the problems confronting modern society, like oil price hikes and environmental hazards that are undeniably causing harm to both humans and Mother Nature.
As a vehicle run by a combination of electricity and gas, a hybrid car can help save fuel and money and reduce air pollution.
Here is how it works.
In a hybrid car, it is not only the engine that is connected to the transmission--the part that passes the power on to the wheels and pushes the car forward--but also an electric motor.
Both the engine and the electric motor can power the vehicle.
The former runs the car and the latter functions when needed to increase power.
This type of hybrid is called parallel.
The other kind is the series hybrid, where a gas engine powers the generator.
The generator then charges the batteries and powers the electric motor.
The gasoline engine doesn't power the car on its own.
The electric motor operates when the car moves below a certain speed and the gasoline engine functions only when that speed is exceeded.
In addition, the engine of a hybrid is smaller than that of the common car, so the car is lighter and more efficient to manage and, hence, less fuel-consuming.
And not only that, when a hybrid car is in motion, it recharges the battery.
When it is running slow, or not moving at all, or when it brakes, it also recharges itself.
Logically, the more electricity the car uses, the less fuel it uses.
This is why hybrid cars don't use as much gas as conventional cars.
This can help you reduce the number of trips to the gas station, saving time, money, energy, and guilt about being an earth pollutant.
