Automatic cars have gained popularity over the years as their technology advances putting them ahead of manual cars.
But auto enthusiasts are still having some uncertainty and confusion surrounding the inner workings of these vehicles. One question that has come up is whether or not automatic cars have flywheels.
This is a valid question since the major difference between these two cars is the transmission, but what about the other components?
The short answer is NO, Automatic cars don’t need a flywheel to function properly. However, some Automatic racing cars come with a flywheel-like component referred to as a flex plate which performs the same function as a flywheel.
Continue reading to find out what a flywheel does and why it isn’t needed in automatic cars.
What is a flywheel?
You need to understand better the role of a flywheel in a manual vehicle before you can decide whether or not they need one.
A flywheel is a mechanical device that stores rotational energy and helps the engine to maintain its speed and smooth delivery.
Manual cars with internal combustion engines have the flywheel connected to the crankshaft to aid in maintaining consistent engine speed by storing the kinetic energy from each combustion stroke.
Also, the flywheel aids in changing gears during acceleration. It helps maintain constant engine speed while switching between gears. This rules out stalling or jerking during the process.
In an automatic car, the flywheel is not needed for proper functioning because they don’t use internal combustion engines.
Instead, they are equipped with electric motors which are powered by charged batteries to aid in driving the vehicle.
Do Automatic Cars have a Flywheel?
So, to answer the question of whether or not automatic cars have flywheels, the answer is no.
Automatic cars do not use an internal combustion engine to power the vehicle, and therefore do not require a flywheel to store and smooth out the delivery of power.
Instead, they use electric motors, which can provide smooth, consistent power to the wheels without the need for a flywheel.
It’s also important to note that the absence of a flywheel does not mean that automatic vehicles won’t perform well or aren’t safe for use.
Electric motors are capable of providing smooth and consistent power to the wheel without the need for a flywheel.
Due to the modern transmission systems, Automatic cars are more improved in terms of performance and efficiency compared to vehicles with traditional internal combustion engines.
However, Flywheels might be present in some Automatic racing cars but they’re referred to as a “flex plate”.
They function similarly to the traditional flywheel the major difference is the build and where it’s located in the vehicle.
In addition, there might also be a component called the torque converter which functions just as a clutch in manual cars.
It is also worth noting that some cars may use a hybrid powertrain, which combines an internal combustion engine with an electric motor.
What is a flywheel called on an automatic?
A flexplate or flex plate is to automatic cars as a flywheel is to manual cars. It connects the engine’s output to the torque converter’s input, which functions as a clutch in automatic cars.
Automatic vehicles do not have flywheels. Instead, they make use of electric motors with advanced transmission systems to move the car.
It’s also important to note that the absence of a flywheel does not alter the performance or safety of the vehicle but even makes it more efficient than some cars running on internal combustion engines.
