How many differentials does AWD have?
As the owner of Kevin's Autos, I often get questions about the intricacies of vehicle systems, particularly when it comes to All-Wheel Drive (AWD) vehicles. One common query is about the number of differentials in AWD systems. In this article, we'll explore the role of differentials in AWD and how many are typically found in these vehicles.
What is a Differential?
A differential is a crucial component in a vehicle's drivetrain that allows the wheels to rotate at different speeds, especially when turning. This is essential for maintaining traction and stability. In AWD systems, differentials play a significant role in distributing power to the wheels effectively.
How Many Differentials Does AWD Have?
Most All-Wheel Drive vehicles are equipped with three differentials:
- Front Differential: This differential is located between the front wheels and allows them to rotate at different speeds, which is particularly important during turns.
- Center Differential: The center differential is unique to AWD systems. It distributes power between the front and rear axles, allowing for better traction and handling on various surfaces.
- Rear Differential: Similar to the front differential, the rear differential allows the rear wheels to turn at different speeds, ensuring smooth handling and stability.
Variations in AWD Systems
While the standard AWD setup includes three differentials, some advanced systems may incorporate additional features:
- Limited-Slip Differentials: These can be found in either the front or rear differentials to improve traction by limiting the speed difference between the wheels.
- Electronic Differentials: Some modern AWD vehicles use electronic controls to manage power distribution more effectively, adapting to driving conditions in real-time.
Conclusion
Understanding the number and function of differentials in AWD systems is essential for any vehicle owner. With three primary differentials working together, AWD vehicles can provide enhanced traction and stability, making them ideal for various driving conditions.

Frequently Asked Questions
Do AWD cars have limited slip differentials?
Sometimes there is a switch or level to turn off the AWD, but unlike 4WD they are perfectly at home on dry pavement while sending power to both axles. This is accomplished with a center differential, and often one that operates with limited slip properties.
Is AWD or 4WD better in snow?
With the right tires, AWD vehicles handle snow well, especially in areas where roads are regularly plowed and gritted. AWD provides more flexibility than 4WD in these situations.
Do AWD cars have a center differential?
Full-time: This type ensures that all four wheels receive power constantly, regardless of the road conditions. Vehicles with full-time AWD have a center differential that allows each wheel to turn at different speeds when turning corners.
Can you drive AWD without front differential?
A vehicle with all-wheel drive AWD or four-wheel drive 4WD can still move without the front driveshaft, but it will only be front-wheel drive. This is because the front wheels are still connected to the engine through the transmission.
How many diffs are in an AWD?
AWD Differential
AWD cars will normally come with three differentials. There's one for the front wheels that allows them a slip, but not necessarily a differential slip. Then there's one for the back wheels that does the same, and then the center differential that mediates the two.
Does AWD have 2 axles?
In contrast, all-wheel drive systems distribute the engine's torque between two axles using a center differential, allowing each wheel to gain traction independently of the others.
Does AWD prevent slipping?
Because AWD and 4WD send power to all four wheels, rather than two, they do provide roughly twice as much traction as a two-wheel-drive vehicle for accelerating in slippery conditions.
Does AWD have a front differential?
With rear-wheel-drive (RWD), the differential is between the rear wheels, connected to the transmission by a driveshaft. All-wheel-drive (AWD) and four-wheel-drive (4WD) vehicles add a centre differential or transfer case to distribute power front and rear.
Do AWD cars have 3 differentials?
Full-time AWD: In this system, the power is directed to all three differentials all the time, which is then sent to all four wheels. Automatic AWD: In this type of system, there is no center differential. The engine sends power to only one differential which powers either the front or rear set of wheels.
What is the disadvantage of AWD?
CON: A False Sense of Security in Wintry Conditions
In snow and slush and on icy roads, AWD reduces wheelspin whenever you're trying to accelerate, but it has no effect on a car's ability to stop or turn in those same poor conditions. AWD sedans neither stop nor turn any better than their two-wheel-drive cousins.
