The SUBARU BOXER Engine The Symmetrical AWD Body & Chassis EyeSight

Wherever your journey takes you.

Subaru’s Symmetrical AWD, which combines a longitudinally mounted Horizontally-Opposed SUBARU BOXER engine for a low center of gravity with a perfectly symmetrical AWD drivetrain, is designed to deliver exceptional stability, safety, and performance in all conditions. The system maximizes traction on any road surface while minimizing chassis roll and pitch, resulting in a smoother, more comfortable ride for all passengers. With different versions tailored to specific models and transmissions, Subaru's Symmetrical AWD consistently ensures a secure and enjoyable driving experience, no matter the terrain or weather.

The Symmetrical AWD

Symmetrical AWD is Subaru's exclusive all-wheel drive system, characterized by its unique symmetrical layout. The powertrain, centered around the horizontally opposed SUBARU BOXER engine, is aligned in a straight line, allowing the vehicle's weight to be distributed evenly across all four wheels. This layout enhances tire grip and delivers exceptional driving performance by fully utilizing the benefits of all-wheel drive. Additionally, the transmission is positioned close to the vehicle's center, while the compact, lightweight engine with a low center of gravity further improves balance. This results in reduced inertia during turns and braking, offering the driver superior handling and stability for a smooth and enjoyable driving experience.

A one-of-a-kind mechanism that ensures optimal performance

Designed to remain stable in unexpected weather conditions, tackle the toughest terrains, and stay true to its course, Subaru’s unique core mechanism offers unmatched stability, traction, and agility. It inspires confidence behind the wheel, no matter your driving experience or skill level, allowing you to handle any challenge the road presents with ease and assurance.

SUBARU provides confidence in unexpected weather

With its well-balanced powertrain, featuring a horizontally opposed engine and a linear, symmetrical layout, Subaru minimizes left-right weight imbalance. This design ensures stable handling, delivering peace of mind even when driving through sudden adverse weather conditions.

SUBARU allows you to move forward confidently no matter the road ahead

SUBARU is committed to AWD as the optimal drive system. By distributing power to all four wheels, AWD ensures that the tires maintain a strong grip on even the most slippery or uneven surfaces, enabling smooth and powerful driving in any condition.

SUBARU ensures you drive with precision

With SUBARU, swaying in all directions is managed, allowing you to stay smoothly on your intended path, even on winding roads or during sudden steering maneuvers.

X-Mode

A single button enhances driving confidence and delivers advanced, SUV-level control. The all-new X-Mode redefines security and peace of mind by seamlessly coordinating the engine, transmission, Symmetrical AWD, and brakes, ensuring safe travel over rough or slippery terrains. Whether it's snowy roads or gravel slopes, X-Mode takes charge, especially when the vehicle picks up speed on a downhill path. With Hill Descent Control, the vehicle's speed is maintained, allowing the driver to focus fully on steering.

Symmetrical AWD: Four Types to Match Every Model

Active torque split AWD
Variable Torque Distribution AWD
Viscous Centre Differential AWD
Multi-mode DCCD

Active torque split AWD

Active Torque Split AWD is an AWD system specifically designed for 4-speed automatic transmissions, E-4AT (with manual mode), and Lineartronic models, aiming to enhance the dependable performance of AWD vehicles in any driving condition. The Lineartronic CVT (Continuously Variable Transmission) uses a chain instead of a belt, offering a broader range of gear ratios for improved performance, efficiency, and quicker throttle response. Normally, the Active Torque Split AWD system distributes torque 60:40 between the front and rear. However, sensors continuously monitor factors like tire grip and vehicle speed, and the electronically controlled Multi-Plate Transfer (MP-T) adjusts torque distribution in real-time. This adaptation to conditions and driver input provides increased stability, ensuring a safe and agile driving experience.

Variable Torque Distribution AWD

Variable Torque Distribution AWD is an AWD system designed specifically for 5-speed automatic transmission models, including E-5AT (with manual mode), providing a more dynamic, sporty driving experience while maintaining the core stability of Symmetrical AWD. With a 45:55 front-to-rear torque distribution, this system sends more power to the rear wheels, helping to reduce understeer, a common issue in 4WD vehicles during cornering, and promoting smoother, more agile handling. The torque distribution is automatically adjusted up to an even 50:50 split between the front and rear wheels, ensuring optimal performance for both sporty driving and stable handling across different road conditions.

Viscous Centre Differential AWD

Viscous Centre Differential AWD is an AWD system designed for manual transmissions, featuring a simple yet effective layout with a center differential and viscous limited-slip differential (LSD). Under normal driving conditions, the system maintains a balanced 50:50 torque distribution between the front and rear wheels, ensuring maximum traction and stability. In situations where wheel slip occurs, or there’s a difference in wheel speed between the front and rear axles, the viscous LSD adjusts the torque distribution, sending power to the wheels with the most grip. This system, paired with the manual transmission's responsive gear shifting, enhances sporty driving while ensuring optimal traction at all times.

Multi-mode DCCD

The Multi-mode DCCD (Driver's Control Centre Differential) in the WRX STI allows drivers to fine-tune the vehicle's handling by adjusting the center differential's locking mechanism. It utilizes a combination of an electromagnetic multi-plate transfer clutch and a mechanical Limited Slip Differential (LSD) to manage torque distribution between the front and rear wheels. In Auto Mode, the system automatically adjusts the power distribution based on changing driving conditions. The Auto [+] setting prioritizes power to the front wheels for improved traction, while Auto [-] shifts more power to the rear wheels for enhanced cornering agility. The six-step Manual Mode allows drivers to lock in their preferred handling characteristics for a more personalized driving experience.
