Understanding Symmetrical AWD Systems in Subaru Vehicles

Introduction to Symmetrical AWD Systems

Subaru is renowned for its Symmetrical All-Wheel Drive (AWD) system, which provides exceptional traction, stability, and control on various road surfaces. This innovative technology has been a hallmark of Subaru vehicles for decades, and it's a key factor in their reputation for safety and reliability. In this article, we'll delve into the different types of Symmetrical AWD systems used in Subaru vehicles, with a focus on the specific system found in all Subaru models except the WRX STI that have a manual transmission.

What is Symmetrical AWD?

Symmetrical AWD is a type of all-wheel-drive system that distributes power evenly to all four wheels. This system is designed to provide optimal traction, stability, and control on various road surfaces, including snow, ice, and off-road terrain. The Symmetrical AWD system used in Subaru vehicles consists of a central differential that splits power between the front and rear axles, and a transfer case that further distributes power between the left and right wheels.

Types of Symmetrical AWD Systems

Subaru offers several types of Symmetrical AWD systems in its vehicles, each designed to provide optimal performance and traction in different driving conditions. The main types of Symmetrical AWD systems used in Subaru vehicles are:

Active AWD: This system is designed for on-road driving and uses a computer-controlled system to distribute power between the front and rear axles. Active AWD is typically used in Subaru vehicles with automatic transmissions.
Variable Torque Distribution (VTD) AWD: This system is designed for on-road driving and uses a viscous coupling to distribute power between the front and rear axles. VTD AWD is typically used in Subaru vehicles with automatic transmissions.
Continuous AWD: This system is designed for off-road driving and uses a continuously variable transfer case to distribute power between the front and rear axles. Continuous AWD is typically used in Subaru vehicles with manual transmissions.
Driver Controlled Center Differential (DCCD) AWD: This system is designed for off-road driving and uses a driver-controlled center differential to distribute power between the front and rear axles. DCCD AWD is typically used in Subaru vehicles with manual transmissions.

Which Type of Symmetrical AWD System is Found in All Subaru Vehicles—Except WRX STI—that Have a Manual Transmission?

Based on the information above, the correct answer is C) Continuous AWD. Continuous AWD is the type of Symmetrical AWD system used in all Subaru vehicles except the WRX STI that have a manual transmission. This system is designed for off-road driving and uses a continuously variable transfer case to distribute power between the front and rear axles.

Benefits of Continuous AWD

Continuous AWD offers several benefits, including:

Improved traction: Continuous AWD provides optimal traction on various road surfaces, including snow, ice, and off-road terrain.
Enhanced stability: Continuous AWD helps to maintain stability and control on uneven road surfaces.
Increased control: Continuous AWD allows drivers to maintain control of the vehicle on steep inclines and declines.
Better fuel efficiency: Continuous AWD is designed to provide optimal fuel efficiency, especially in on-road driving conditions.

Conclusion

In conclusion, the type of Symmetrical AWD system found in all Subaru vehicles—except WRX STI—that have a manual transmission is Continuous AWD. This system is designed for off-road driving and uses a continuously variable transfer case to distribute power between the front and rear axles. Continuous AWD offers several benefits, including improved traction, enhanced stability, increased control, and better fuel efficiency. Whether you're driving on snow-covered roads or navigating off-road terrain, Continuous AWD is the perfect choice for Subaru vehicles with manual transmissions.
