The term flywheel conjures up images of manual gearbox cars. A manual transmission’s flywheels play a significant role in energy storage and release.

As a result, the car moves more easily and the driver has more control over it. Is there a flywheel in an automated car?

The driver of an automatic car does not have to worry about shifting gears by hand. Because they use automatic mechanisms to change gears rather than manual controls, these vehicles are known as automatic transmissions.

Because automatic cars do not rely on the driver’s actions during operation, they can be utilized by anyone without prior experience.

What is a Flywheel?

In order to store energy, flywheels use a rotating disk known as a flywheel. It accomplishes this by rapidly whirling and then settling down. Other gadgets or the automobile itself could benefit from this extra energy.

So, Do Automatic Cars Have a Flywheel?

Automatic cars, particularly racing vehicles, may be equipped with a flywheel, which is referred to as a flexplate. The flywheel, which is located between the engine and the gearbox in the rear of the vehicle, is unrelated to the vehicle’s automation. Some form of toothed device lets the starter to get the engine going in every vehicle.

There are some automated cars that do not utilize a flywheel to regulate speed and instead rely on hydraulic pumps and electromagnetic clutches that are much smaller than their mechanical equivalents.

Despite the fact that these components can perform the same activities as a flywheel, their size and power consumption limit their use to only small capacities.

How does a Flywheel in a Manual Transmission Vehicle?

It is impossible to drive a manual gearbox car without a flywheel. One of the most critical mechanisms in a manual gearbox automobile is the flywheel.

Rotational energy can then be employed to propel the vehicle forward or backward, depending on the situation. The engine’s speed is also controlled by the flywheel, which keeps it running at a constant rate even if the rotational speed changes. Here are a few examples of its capabilities:

1. Store energy when it’s available and supply it when it’s needed

When the car is traveling at a high rate of speed, the flywheel assists to retain energy. When the car needs it, such as when it’s beginning or climbing a hill, this energy can be released.

2. Help the engine run more smoothly

The flywheel helps to distribute the engine’s power evenly. As a result, the engine runs more smoothly and is less jarring. The engine can stall if the speed changes suddenly.

3. Enhance ride quality

A flywheel in a manual transmission improves the vehicle’s ride quality by making movement more manageable.

How can a flywheel work in automatic cars?

There are others who are baffled as to how a flywheel can function in an automatic car. Due to the four cycle technique already used by automatic vehicles, each power stroke has two revolutions instead of one. Automated vehicles would not be able to attain their full speed without a separate gadget to store energy. If you’re looking to store energy, the flywheel can assist you out. This improves the car’s top speed and reduces its fuel consumption.

How does the flywheel work: A step-by-step process

Do Automatic Cars Have A Flywheel

After learning how flywheels in automatic cars function, let’s take a closer look at the mechanism:

The flywheel is attached to the crankshaft, which spins it

Attaching the flywheel to the crankshaft is the first step. This kicks things into overdrive.

When you press your car’s accelerator, that sends power through a drive shaft

In response to a driver’s application of gas, an engine’s gears begin to revolve, transferring power to the transmission and then to the flywheel.

The flywheel makes use of centrifugal force to transfer that energy into momentum

Large gear on the flywheel’s outer surface turns faster than the crankshaft when this occurs, causing the flywheel to spin at an extremely high pace. Centrifugal force kicks in here. As a result of this outer gear’s fast rotational speed, the flywheel’s outside circumference gains momentum from the gears.

The momentum is converted into kinetic energy

In order to move forward or reverse, the car uses the kinetic energy that is created when momentum is transmitted to the flywheel.

The flywheel then releases that energy to the transmission

An electric motor in the flywheel transfers power to a transmission when it reaches its maximum rotational speed. This will aid to propel the vehicle forward or backwards as needed.


Automatic gearbox cars include something called a flywheel, which stores rotational energy and subsequently powers the car forward or backward depending on the driving situation at hand. It also aids in speed regulation, making for a more comfortable ride.

Flywheels allow automatic cars to accelerate more quickly to their top speeds because they can store and release kinetic energy as needed. Both manual and automatic automobiles use flywheels for a variety of other purposes that benefit the vehicle’s performance.
