Symmetrical AWD, comprising of a longitudinally mounted Horizontally-Opposed SUBARU BOXER engine which achieves the low center of gravity and a symmetrically designed AWD drivetrain, is the system that Subaru has focused on for the best stability, safety and on-road performance at all times on all roads and in poor conditions. And it provides works with the outstanding traction of AWD to limit the chassis rolling and pitching, increasing ride comfort and making the journey enjoyable for all passengers. Subaru’s Symmetrical AWD comes in a variety of different systems depending on the vehicle type and the transmission used.
Symmetrical AWD, Subaru’s own four-wheel drive system. Its greatest feature is that the powertrain, the core of which is the horizontally opposed engine, is symmetrically laid out in a straight line. As the four wheels bear weight equally with this basic layout, the road-hugging property of the tires is excellent and outstanding driving performance is achieved. It maximizes the potential of four-wheel drive. In addition, with symmetrical AWD, the heavy transmission is located near the center of the vehicle. Furthermore, the engine is the light, compact, and low center-of-gravity horizontally opposed engine. Due to its superior weight balance, the moment of inertia is low when turning and braking so the driver can enjoy the superior handling. At the same time, as the vehicle is stable and comfortable, the driver can enjoy a pleasant drive.
Stable even in sudden bad weather. Challenges the roughest roads. Runs along the intended line. And lets you drive with confidence regardless of your driving skill. SUBARU’s original core mechanism heightens stability, traction and agility to deliver such ideal performance.
SUBARU delivers peace of mind even in sudden bad weather
SUBARU’s power train is well-balanced with a horizontally opposed engine and transmission in a linear and symmetrical layout which minimizes left/right weight difference. This delivers stable driving for peace of mind even in sudden bad weather.
One button elevates driving confidence and provides advanced, SUV-like control. The all-new X-Mode brings a whole new meaning to security and peace of mind, regardless of how rough or slippery a road may be as it works to coordinate the engine, transmission, Symmetrical AWD and brakes to safely drive over almost any type terrain. X-Mode assists in those cases where the vehicle starts moving faster as it drives downhill, like when driving down snowy roads or gravel slopes. Hill Descent Control maintains the vehicle’s speed so the driver can focus more on steering.
Active torque split AWD
An AWD system developed exclusively for 4-speed automatic transmission, E-4AT (with manual mode) and Lineartronic models to maximise the reliable driving performance of AWD models under any driving conditions. The Lineartronic CVT (Continuous Variable Transmission) uses a chain instead of a belt—allowing a greater span of overall ratios for improved performance and efficiency as well as a faster response to throttle input. The active torque-split AWD system usually distributes torque 60:40 front and rear, however sensors constantly monitor the vehicle’s condition in areas such as changes in grip of the front and rear tyres or vehicle speed. The electronically controlled MP-T (Multi Plate Transfer) adjusts torque distribution to the front and rear tyres in real-time to suit driving conditions, as well as the transmission and driver inputs. This further increases the stability of the AWD system to deliver a safe and agile driving experience.
