Subaru Symmetrical All Wheel Drive

Every all-wheel drive system is not the same. In 1972, we began developing our all-wheel drive system with a commitment to simplicity, to working in harmony with the forces of nature, and to making every moment behind the wheel a rewarding experience. Nearly 40 years worth of development later, Subaru Symmetrical All-Wheel Drive stands out from the crowd with advantages like the stability of its almost total side-to-side symmetry, the brilliant efficiency of its power delivery, and its quick response to wheel slippage.

Better Balance

We build every Subaru model with all-wheel drive from the ground up. Each one features the longitudinally mounted SUBARU BOXER® engine. Designed to work in concert with Subaru Symmetrical All-Wheel Drive, it feeds power into the system in a straight line. Some other AWD systems  need extra components to direct engine power through multiple turns in order to get it to each of the wheels. The resulting simplicity allows us to build a balanced, more efficient drivetrain with nearly perfect side-to-side symmetry. Better balance means stability that helps make driving safer and agility that makes it more fun.

Quick Response

The more your wheels are engaged with the road, the more control you have. Some other AWD systems engage all four wheels only when a loss of traction is detected. By then, your control has already been compromised. Subaru Symmetrical AWD keeps power routed to all four wheels all the time, helping to better prevent slippage before it happens. And if slippage does occur, its simple and efficient design -- with power flowing in one direction and minimal mechanical components -- allows it to respond more quickly. It immediately reduces engine power to the slipping wheel and gives it to the wheels that have traction.

Efficient Design

Because some systems lack the simplicity of Subaru Symmetrical AWD, they therefore not only sacrifice efficiency, but also can incur more wear and tear. The engine on a Subaru is mounted longitudinally -- in line with the driveshaft -- so power routes directly from the engine to all four wheels. The components of some other systems -- like those with transversely mounted engines -- needed to change the direction where power flows are not needed on a Subaru. Less components means less things to break down, and it also means less power loss due to friction. And with power continually flowing with maximum efficiency, you experience the advantage of seamless traction whenever you need it.
