How Do Hybrid Cars Work?

By: Jennifer Maughan

How do hybrid cars work? If you've ever thought about buying a hybrid car or ridden in one, you may have wondered how something so quiet gets that much power. To gain an understanding of hybrid vehicles, it's necessary to analyze the hybrid car technology and see how it's been utilized to create a more efficient and less harmful option for drivers.

Hybrid Vehicles
When a vehicle combines power generated from more than one source, it's a hybrid. Examples of non-automotive hybrids include submarines, locomotives and even electric buses. The cars available on the market today are gasoline and electricity hybrids, and they gain 20 to 30 miles more to the gallon on average. Since the late 1990s, hybrid cars have been available to regular buyers, and today most of the major car manufacturers are either creating hybrids or are actively working to start.

Hybrid Car Technology
A gasoline engine in a hybrid car is much like any other-but hybrid engines are smaller and more efficient than the engines in traditional cars. An electric motor supplies power to the vehicle, and each hybrid will also come with batteries that supply the car with stored energy from the electric motor. The battery is also recharged when the vehicle brakes are applied.

Two Sources To One
The two power sources, the gas engine and the electric motor, combine to provide power to the transmission. The transmission then turns the wheels of the car. Sophisticated technology and computer applications allow the electric motor to stop and start as needed, as well as take over for the gasoline engine. Especially during driving moments that tend to waste gasoline, such as startup and idling, electric motors can reduce the amount of gasoline used.

Other Elements Of Hybrid Design
Increased fuel efficiency is the main purpose of hybrid cars. It takes less gasoline to get from here to there in a hybrid compared to a traditional internal combustion engine car. The hybrid stores kinetic energy from braking in the battery, constantly recharging it. Hybrid car designs also emphasize fuel efficiency techniques, such as reducing drag from around the vehicle by using aerodynamic designs and stiffer tires. The weight of the hybrid is also reduced because it is built with strong but lightweight materials, like carbon fiber. Every aspect of a hybrid car works to help you get the most out of the gasoline that you buy.
