The Subaru Legacy’s All Wheel Drive system is a standard feature that sends power to all four wheels simultaneously, providing better grip and balance on the road. This Subaru All Wheel Drive setup is perfect for San Diego because it helps you handle slippery coastal roads and foggy morning drives with total confidence.

Simply put, this All Wheel Drive in the Legacy acts like a smart helper, constantly checking for wheel slip and moves power to the tires with the most traction to keep you safe. In this guide, we’ll have a closer look at how this always-on system works to keep every drive safer.

What is the All Wheel Drive System Technology in a Subaru?

When people ask what is All Wheel Drive system in a Subaru, they usually refer to the Subaru Symmetrical All Wheel Drive. Unlike some other cars that only use two wheels until they slip, a Subaru uses all four wheels all the time. 

The word “symmetrical” means the whole system sits right in the middle of the car from front to back. This creates a balanced feel, much like a seesaw that stays level instead of tipping to one side. Because the weight is spread out evenly, the car feels more stable when you turn or drive over bumps.

What Makes the Subaru Legacy All Wheel Drive System Different?

Unlike its competitors, every 2025 Legacy gets this system as standard equipment, not as an expensive add-on. The flat 2.4-liter BOXER engine sits low in the chassis, paired directly with the All Wheel Drive components. This creates a center of gravity that makes the car feel planted, even when taking I-5 exit ramps at speed.

The Subaru All Wheel Drive monitors each wheel hundreds of times per second. When sensors detect one wheel slipping, the system instantly redirects power to the wheels with better grip. You stay in control without jerking the steering wheel or pumping the brakes.

Why San Diego Drivers Need the Subaru All Wheel Drive Design

Even though San Diego is famous for sunshine, local drivers still face tricky conditions that make Subaru All Wheel Drive useful. Coastal fog can make the roads damp and slick in the mornings, especially along the Pacific Coast Highway. 

If you drive up to Julian or the Laguna Mountains, you might encounter light snow or icy patches in the winter. The Subaru Legacy All Wheel Drive system ensures that if one tire hits a puddle or a slippery road, the other three tires work harder to keep you moving straight. 

Overall, the 2025 Subaru Legacy’s AWD system helps prevent the car from sliding sideways, giving you peace of mind on busy freeways.

Understanding the Subaru Active Torque Split Feature

The 2025 Subaru Legacy uses a specific type of technology called Subaru Active Torque Split. This system works with the Lineartronic Continuously Variable Transmission (CVT) to manage how much power goes to the front and back wheels. 

Under normal driving conditions, it usually sends about 60% of the power to the front and 40% to the rear. Sensors inside the car monitor detect how fast the wheels are turning, how much you are pressing the gas, and how you are braking. 

If these sensors notice the front wheels are spinning too fast, the system instantly sends more power to the back wheels to help you regain grip. The active torque split is a proactive system; it tries to guess when you need extra help before you even feel the car slip.

Key Benefits of the Subaru for San Diego Daily Driving

San Diego drivers face unique conditions that make the best All Wheel Drive system essential. 

Stable Driving No Matter The Weather

Summer heat can make slick road conditions with oil during the first rain. Fall brings morning marine layers that leave highways damp. Winter occasionally delivers actual storms that turn freeways into skating rinks for Rear Wheel Drive sedans.

The Subaru All Wheel Drive prevents hydroplaning better than two-wheel systems. When your front tires start floating over standing water on I-805, the rear wheels maintain forward momentum and steering response. You stay in your lane instead of drifting sideways.

Excellent Fuel Economy

Fuel economy remains excellent despite having power at all four corners. The 2025 Legacy achieves up to 35 MPG on the highway, and the turbocharged Touring XT still manages 29 MPG combined. Your gas budget stays reasonable even with San Diego’s premium fuel prices.

Works In Sync With Subaru Legacy’s Safety Features

The All Wheel Drive system works hand-in-hand with EyeSight Driver Assist Technology. EyeSight uses two cameras near the rearview mirror to act like an extra set of eyes on the road, automatically applying the brakes if it detects a potential crash ahead. 

Because the car has the grip of the Subaru All Wheel Drive system, these safety systems can work even better to stop the car or steer away from danger. The Legacy’s pre-collision braking can also engage faster when the car knows all four wheels can help slow you down. 

Adaptive cruise control maintains spacing more smoothly because the system can modulate power to all wheels. Lane-keep assist feels more confident because AWD helps maintain your path through gentle corrections.

The 2025 model also includes DriverFocus, which uses a camera to see if the driver is getting sleepy or distracted. These technologies combine with the steady traction of the AWD system to earn the Legacy top safety marks from groups like the IIHS.

Safety ratings back up this confidence. The 2025 Legacy earned Top Safety Pick from IIHS with Good ratings in small overlap front crash tests. NHTSA gave it five stars overall. The combination of ring-frame body construction, eight airbags, and All Wheel Drive creates multiple layers of protection.

Inside, you get more room than a Toyota Camry or Nissan Altima with 105.5 cubic feet of passenger space. The trunk holds 15.1 cubic feet of gear. Take surfboards to Blacks Beach or load camping equipment for Anza-Borrego, and the All Wheel Drive system handles the extra weight without complaint.

Following the Subaru Maintenance Schedule for your AWD Sedan

To keep your car running perfectly, you must follow the Subaru maintenance schedule. With all four wheels connected to the power system, keeping everything in top shape is important for the health of the transmission. 

The standard Subaru Legacy maintenance schedule recommends a minor service every 6,000 miles or every six months. During this visit, experts will:

• Change your oil and filter using special synthetic oil designed for the BOXER engine.
• Perform a tire rotation

If your tires do not wear down evenly, it can put extra stress on the AWD parts and lead to expensive repairs later.

Key Intervals in the Subaru Legacy Maintenance Schedule

As your car gets older, the Subaru maintenance schedule includes more detailed checks. 

• At the 30,000-mile mark, a technician should check the fluids in your differentials and transfer case. These fluids help the AWD system move power between the wheels smoothly. 
• At 60,000 miles, the Subaru Legacy maintenance schedule calls for a full inspection of the drive system and AWD fluid replacement. 

San Diego drivers should also remember to rinse the underside of the car if they drive near the beach often. Salt and sand from the ocean can cause wear on the metal parts over time.

Expert Tips for Maximizing Your All Wheel Drive Performance

To get the most out of your Subaru All Wheel Drive, follow these expert-backed tips in maintaining it:

• Always keep an eye on your tire pressure. If one tire is low, it changes how fast that wheel spins compared to the others, which can make the AWD system work too hard. Do this monthly since San Diego temperature swings affect inflation.
• Make sure all four tires are the same brand and have the same amount of tread wear.
• Replace all four tires at once if you have a flat tire that cannot be repaired. This keeps the system balanced.
• Avoid “rocking” your car if stuck in sand at the beach. Rapidly switching between drive and reverse while spinning wheels generates heat that damages the Active Torque Split clutch. Instead, use a gentle throttle and let the system work gradually.
• Engage X-Mode if you’re driving a Legacy trim with this feature to adjust the throttle response while holding the gears longer for better control.
• Use all-season tires instead to maintain the grip no matter the weather or terrain of the place you’re heading to.

When driving in the rare San Diego rain, remember that AWD helps you go. But it does not help you stop any faster than a normal car. Always leave space between you and the car in front of you.

And, don’t forget that annual inspections catch small problems before they become expensive. Even if your Subaru maintenance intervals allow longer gaps, having a certified technician examine the AWD system yearly provides peace of mind. Dalton Subaru National City runs multi-point checks that cover every component.
