What makes Subaru’s signature Symmetrical All-Wheel-Drive so special? Subaru Symmetrical All-Wheel Drive (AWD) is a unique drivetrain technology known for its effectiveness in providing enhanced traction, stability, and control. Subaru’s Symmetrical AWD system has become one of the brand’s defining features. This advanced AWD system offers several advantages over traditional drivetrain configurations and has contributed to Subaru’s reputation for safety and performance. In this blog post, we will delve into the details of Subaru Symmetrical AWD, exploring its design principles, benefits, and how it sets Subaru apart from other manufacturers.
At the core of Subaru’s Symmetrical AWD is a commitment to balance and symmetry. Unlike many other AWD systems, which are retrofitted onto existing front-wheel-drive platforms, Subaru’s AWD is engineered as an integral part of the vehicle’s design. The system is based on a longitudinally mounted horizontally opposed engine, also known as a boxer engine, and a symmetrical drivetrain layout. This means that the engine and transmission are aligned in a straight line, with the transmission output sent directly to the front and rear wheels.
The symmetrical layout plays a pivotal role in the performance and handling characteristics of Subaru vehicles. By having the engine and drivetrain components arranged in a symmetrical manner, the weight distribution is more evenly balanced, resulting in improved stability and predictable handling. This configuration also helps to minimize the overall length of the powertrain, reducing rotational inertia and enhancing the vehicle’s responsiveness.
The symmetrical nature of the AWD system is further enhanced using a center differential. The center differential is responsible for distributing power between the front and rear axles, allowing the system to adapt to changing road conditions. In normal driving situations, the power distribution is biased towards the front wheels, providing the efficiency and handling benefits of a front-wheel-drive vehicle. However, when wheel slip or loss of traction is detected, the system can instantly redistribute power to the wheels with the most grip, maximizing traction and stability.
A key advantage of Subaru’s Symmetrical AWD system is its proactive nature. Unlike some reactive AWD systems that only engage the rear wheels after detecting wheel slip, Subaru’s AWD system is always active and provides continuous power to all four wheels. This proactive engagement ensures that the vehicle is ready to respond to changes in traction at all times, improving safety and control. The seamless transfer of power between the front and rear wheels enhances cornering stability, especially in challenging driving conditions such as rain, snow, or rough terrain
Moreover, Subaru has incorporated advanced technologies to enhance the performance of their Symmetrical AWD system. One such feature is the Vehicle Dynamics Control (VDC), which monitors various vehicle parameters, including wheel speed, steering input, and lateral g-forces. In the event of a loss of control or a skid, the VDC system can automatically adjust the torque distribution, apply individual wheel braking, or reduce engine power to help the driver regain control. This integration of stability and traction control further enhances the safety and responsiveness of Subaru vehicles equipped with Symmetrical AWD.
Subaru’s commitment to safety extends beyond its technological advancements. The company has a long-standing reputation for building durable and reliable vehicles. This dedication is reflected in the rigorous testing and development processes employed by Subaru engineers. Symmetrical AWD is designed not only to enhance performance but also to improve safety by minimizing the risk of loss of control and maximizing driver confidence.
In summary, Subaru Symmetrical All-Wheel Drive is a unique drivetrain technology that sets Subaru apart from other manufacturers. With its balanced and symmetrical design, proactive power distribution, and advanced control systems, Symmetrical AWD delivers enhanced traction, stability, and control in various driving conditions. Subaru’s commitment to safety, performance, and durability has made Symmetrical AWD a hallmark.

Common Car Warning Lights
Modern cars are technologically advanced machines with lots of sensors and electrical systems that constantly monitor themselves. And of course, we depend on our vehicles for commuting, recreation, running errands and getting work done on the jobsite.
So, when you see warning lights on your dash that you don’t recognize, it can certainly be a bit worrisome. Let’s explore a few of the most common warning lights and what each one means.
Check Engine
Oh no! The dreaded check engine light! While it seems like the scariest, this light is one the most ambiguous because it relates to many things having to do with the car’s motor and emissions system.
The potential issue could be as minor as an ill-fitting gas cap. Or it could mean something far more serious is wrong.
If the check-engine light illuminates while you’re driving and everything seems fine with the car, don’t panic, but don’t ignore it, either. Get the vehicle to our service center to run a diagnostic test and source the problem. Should the light turn on and the vehicle suddenly begins operating erratically or making strange noises, pull over immediately and call for a tow. This means there’s a far more serious problem. And NEVER ignore a blinking check-engine light. Ignoring a blinking check-engine light could mean putting yourself at risk, and ruining your car’s powertrain.
Battery:
The battery warning is easy to decipher because it looks exactly like the thing that needs attention. For many car owners, this light conjures up the heart-sinking ‘click, click’ sound of a vehicle trying to start with a dead battery.
Don’t be fooled if the battery light illuminates but the car starts up and drives normally. There could be a long-term issue with the battery itself, or potential problems with the vehicle’s wiring, alternator, or other electrical components. Again, don’t ignore this light because a battery issue means that you might not be able to start your car when you most need it.
Tire Pressure Monitoring System:
This light looks like a horseshoe with an exclamation point in the middle. In many modern cars, the tire pressure monitors include a display to tell the driver the exact tire pressure at each wheel.
As an example, if one tire shows significantly less air pressure than the others, stop the car and refill the tire to the correct pressure rating. Start the car and see if the warning light goes off after a few minutes. If it doesn’t, there could be damage to the tire that’s causing a rapid leak. Also note that this is a common sight during winter because cold temperatures affect tire pressures.
Of course, there are lots of other lights and indicators that can pop up. Refer to your owner’s manual or stop in at one of our service centers.
