AWD systems provide a number of advantages over 2WD systems, including improved traction, stability, and handling. This is especially beneficial in slippery conditions, such as snow, ice, or rain.

The Subaru all-wheel drive system is a complex and sophisticated piece of engineering. It works by using a series of differentials and clutches to distribute power to all four wheels, providing excellent traction and stability in all conditions. However, some Subaru models have been known to experience oil consumption problems.

Has Subaru fixed the oil consumption problem ? The answer is yes, Subaru has taken steps to address this issue in recent years. By redesigning the piston rings and using a different type of oil, Subaru has been able to significantly reduce oil consumption in its vehicles.

As a result, Subaru owners can now enjoy the benefits of all-wheel drive without having to worry about excessive oil consumption.

Significance of Subaru’s AWD System

Subaru is a Japanese automaker that has been producing AWD vehicles since the 1970s. Subaru’s AWD system is considered one of the best in the industry, and it is a major selling point for the company’s vehicles.

Subaru’s AWD system is unique in that it uses a symmetrical layout, with the engine, transmission, and drivetrain all located in the center of the vehicle. This layout helps to distribute weight evenly and provides for a more balanced and stable driving experience.

Components of Subaru AWD

Subaru’s AWD system consists of several core components, each playing a crucial role in distributing power to all four wheels for enhanced traction and stability.

Central Differential

The central differential is the heart of the AWD system. It divides the engine’s power between the front and rear axles, ensuring a balanced distribution under various driving conditions.

Front and Rear Differentials, How subaru awd works

The front and rear differentials are located at the axles and further distribute power to each individual wheel. They allow the wheels to rotate at different speeds when cornering or navigating uneven terrain, preventing wheel slip.

Driveshafts

Driveshafts connect the transmission to the differentials and axles, transferring power from the engine to the wheels. They ensure smooth and efficient power delivery.

Axles

Axles are solid shafts that transmit power from the differentials to the wheels. They are responsible for carrying the vehicle’s weight and providing a stable connection between the wheels and the suspension.

Electronic Control Unit (ECU)

The ECU is the brain of the AWD system. It monitors driving conditions and adjusts the power distribution between the wheels accordingly. It ensures optimal traction and stability by managing the system’s components.

Working Principle

Subaru’s AWD system is renowned for its ability to distribute power to all four wheels, providing exceptional traction and handling in various driving conditions. The key to this system lies in the center differential, which plays a crucial role in power distribution.

The center differential is a mechanical device that allows the front and rear axles to rotate at different speeds, ensuring that power is distributed evenly between the wheels. When driving on a straight road, the center differential locks, sending equal power to both axles.

However, when the car encounters turns or uneven terrain, the center differential unlocks, allowing the wheels to rotate at different speeds, preventing the car from binding or losing traction.

Role of the Center Differential in Power Distribution

The center differential plays a critical role in ensuring optimal power distribution to all four wheels. It operates in two primary modes:

• Locked Mode:In this mode, the center differential locks, sending equal power to both the front and rear axles. This is ideal for driving on straight roads or in situations where maximum traction is required.
• Unlocked Mode:When the car encounters turns or uneven terrain, the center differential unlocks, allowing the front and rear axles to rotate at different speeds. This prevents the car from binding or losing traction, ensuring smooth handling and stability.

Advantages of Subaru AWD

Subaru’s AWD system provides numerous advantages in various driving conditions. It enhances traction, stability, and handling, making it an ideal choice for drivers who demand performance and safety in all-weather conditions.

Enhanced Traction

AWD distributes power to all four wheels, ensuring that each wheel receives the optimal amount of torque. This results in improved traction on slippery surfaces, such as snow, ice, and mud. The system helps prevent wheels from slipping, providing better acceleration and control.

Improved Stability

By distributing power to all wheels, AWD helps maintain vehicle stability, especially when cornering or driving on uneven terrain. The system reduces the risk of oversteer or understeer, making the vehicle more responsive and predictable.

Exceptional Handling

AWD improves handling by providing better grip and control in all driving conditions. The system helps keep the vehicle planted on the road, reducing body roll and improving overall agility. This enhances the driving experience, making it more enjoyable and confident.

Types of Subaru AWD Systems

Subaru has developed several types of AWD systems to cater to different vehicle models and driving conditions. These systems vary in terms of their design, capabilities, and applications.

The three main types of Subaru AWD systems are:

Symmetrical All-Wheel Drive (SAWD)

The Symmetrical All-Wheel Drive (SAWD) system is the most common type of AWD system used by Subaru. It is a full-time AWD system that provides power to all four wheels at all times, even when driving on dry pavement. The SAWD system is designed to provide optimal traction and stability in all driving conditions, including snow, ice, rain, and off-road.

Active All-Wheel Drive (AWD)

The Active All-Wheel Drive (AWD) system is a part-time AWD system that only engages the rear wheels when needed. The AWD system is designed to improve fuel economy by reducing power loss when driving on dry pavement. The AWD system is typically used on smaller, more fuel-efficient vehicles.

Variable Torque Distribution (VTD) AWD

The Variable Torque Distribution (VTD) AWD system is a full-time AWD system that can vary the amount of torque sent to the front and rear wheels. The VTD system is designed to provide optimal traction and stability in all driving conditions, including snow, ice, rain, and off-road.

The VTD system is typically used on higher-performance vehicles.

Maintenance and Care

Maintaining Subaru’s AWD system is crucial for optimal performance and longevity. Regular inspections and fluid changes are essential.

Inspections should include checking fluid levels, inspecting driveshafts and boots for leaks or damage, and examining tires for uneven wear. Fluid changes should be performed according to the manufacturer’s recommendations, typically every 30,000 to 60,000 miles.
