Do subarus have two differentials?
Subaru vehicles are renowned for their all-wheel-drive (AWD) systems, which provide excellent traction and stability in various driving conditions. A common question among Subaru owners and enthusiasts is whether these vehicles have two differentials. In this article, we’ll explore the role of differentials in Subaru vehicles and clarify how many they typically have.
Understanding Differentials in AWD Vehicles
A differential is a crucial component in a vehicle's drivetrain. It allows the wheels to rotate at different speeds, which is essential when turning corners. Without a differential, the wheels would struggle to rotate properly, leading to excessive tire wear and poor handling.
In all-wheel-drive vehicles like Subarus, differentials play an even more critical role. They help distribute power between the front and rear wheels, as well as between the left and right wheels, ensuring optimal traction and performance.
How Many Differentials Do Subarus Have?
Most Subaru vehicles equipped with their signature Symmetrical All-Wheel Drive system have two differentials:
- Front Differential: This differential is located between the front wheels and manages the power distribution between the left and right front wheels.
- Rear Differential: This differential is located between the rear wheels and handles the power distribution between the left and right rear wheels.
In addition to these two, many Subaru AWD models also feature a center differential or a similar mechanism (such as a viscous coupling or an electronic control system). The center differential is responsible for splitting power between the front and rear axles, ensuring balanced traction across all four wheels.
Why Are Subarus Equipped with Multiple Differentials?
The use of multiple differentials in Subaru vehicles is a key factor in their exceptional handling and stability. Here’s why:
- Improved Traction: By distributing power effectively, the differentials help maintain grip on slippery or uneven surfaces.
- Enhanced Cornering: Differentials allow the wheels to rotate at different speeds, making cornering smoother and more efficient.
- Balanced Power Delivery: The center differential ensures that power is evenly distributed between the front and rear axles, preventing wheel slippage.
Conclusion
To answer the question: Yes, Subarus typically have two differentials—a front and a rear differential. Additionally, many models include a center differential or an equivalent system to manage power distribution between the axles. This setup is a cornerstone of Subaru’s Symmetrical All-Wheel Drive system, providing the reliability and performance that Subaru drivers have come to expect.

Frequently Asked Questions
How many differentials does a Subaru have?
Subaru offers four different all-wheel drive systems for their models. The only model that doesn't offer all-wheel drive is the BRZ, which is rear-wheel drive. Each of these systems offers an open differential in the front and rear, except on the STI which has its own system.
Does AWD have two differentials?
4WD differentials transfer the same amount of torque to all four wheels to make them move at the same time. Conversely, AWD supplies differing amounts of torque to each tire. 4WD normally has 2 differentials, while AWD can have up to three.
Does Subaru have a rear differential?
This VCD system is used on all manual transmission models, like the Crosstrek, Impreza, and Forester. The torque is split 50/50 between the front and rear wheels and includes an open front and rear differential.
Does Subaru have a front differential?
All-wheel drive Subarus have both front and rear differentials. The fluid in the differential system breaks down over time and will eventually need to be replaced.
