Subaru's Symmetrical AWD and X-MODE: The Winter Confidence Duo Ontario Drivers Trust
December 30 2025,
When Ontario winters throw everything at you—black ice on Highway 400, deep snow in cottage country, or freezing rain across Vaughan—you need more than basic all-wheel drive. You need a system engineered to handle the unpredictable, the treacherous, and the downright intimidating. Subaru's Symmetrical Full-Time AWD and X-MODE technology deliver exactly that: a partnership designed to turn winter's worst conditions into confident, controlled drives.
For over 40 years, Subaru has refined its Symmetrical AWD architecture to deliver full-time traction, balanced handling, and dependable performance across all seasons. Add X-MODE to the equation, and you unlock advanced off-road capability that tackles steep inclines, slippery surfaces, and deep snow with precision. Together, these systems don't just react to winter—they dominate it.
Why Symmetrical Full-Time AWD Changes the Game
Subaru's Symmetrical AWD isn't an afterthought bolted onto an existing design. It's a ground-up engineering philosophy that places the engine, transmission, and centre differential along the vehicle's centreline for optimal balance. This layout delivers smoother power delivery, greater stability in corners, and a lower centre of gravity that keeps the vehicle planted in challenging conditions.
Unlike front-wheel drive (FWD) systems that struggle under acceleration and lose traction in snow, or part-time AWD systems that only engage when slip is detected, Symmetrical Full-Time AWD is always active. Power flows to all four wheels continuously, maximizing grip from the moment you press the accelerator. When one wheel hits ice or loose gravel, the other three remain powered to maintain forward momentum and control.
Key advantages of Symmetrical Full-Time AWD:
- Always engaged—no delay waiting for the system to activate
- Balanced power distribution reduces wheelspin and improves stability
- Lightweight, efficient design with fewer components than truck-based 4WD systems
- Fuel economy comparable to FWD on most models
How X-MODE Elevates Performance Beyond AWD
While Symmetrical AWD handles everyday winter driving with confidence, X-MODE takes capability to the next level. Available on Ascent, Crosstrek, Forester, and Outback models equipped with the Lineartronic CVT, X-MODE is a driver-engaged system that optimizes engine output, transmission behaviour, AWD torque split, and braking to conquer the toughest conditions.
When you activate X-MODE with a push of a button, the system prepares the vehicle for low-traction scenarios that demand more than standard AWD can deliver. Select models offer a dual-function X-MODE with two settings: Snow/Dirt mode for moderate conditions and Deep Snow/Mud mode for extreme terrain.
X-MODE in Action: Real-World Scenarios
Climbing Steep Inclines:
When tackling a snow-covered hill or uneven trail, X-MODE uses lower gear ratios to generate extra power at the wheels with the most grip. The transmission control unit increases AWD clutch pressure by 25% to control rotational differences between the front and rear wheels, delivering added stability and forward momentum.
Navigating Slippery Surfaces:
X-MODE makes the traction control system more sensitive, significantly reducing the time needed for a wheel to regain traction after slipping. Power is instantly diverted away from spinning wheels and toward those with better grip. If needed, the system can deactivate the transmission's lock-up clutch to better direct power to slipping wheels, maintaining stability when driving at speed.
Descending Steep Slopes:
Hill Descent Control (HDC), integrated into X-MODE, maintains a constant speed below 20 km/h on steep declines without requiring brake input. The system reads road conditions and applies brake pressure to each wheel independently, allowing you to focus exclusively on steering while it handles braking—especially valuable on slippery, rugged, or uneven slopes.
The Symmetry Advantage: Engineering That Works as One System
What sets Subaru apart is the seamless integration of every drivetrain component. The horizontally opposed BOXER engine sits low and compact, linked to a lightweight transmission and differential—all positioned longitudinally along the vehicle's centreline. This configuration creates ideal left-to-right balance, reduces dive under hard braking, and minimizes yaw (the tendency to spin).
Equal-length axle shafts front and rear eliminate torque steer and maximize tire contact with the road, no matter the surface. Independent, long-travel suspension further enhances stability and control, ensuring the vehicle responds predictably in all conditions.
Symmetry delivers:
- Optimal side-to-side balance for smoother cornering
- Lower centre of gravity for improved handling and stability
- Efficient power transfer with minimal energy loss
- Reduced complexity for greater reliability and lower maintenance costs
Full-Time AWD vs. Part-Time Systems: Why Always-On Matters
Part-time (on-demand) AWD systems operate in two-wheel drive most of the time and only switch to AWD when sensors detect slip. This reactive approach introduces delays and limitations:
- The system may not react quickly enough to sudden traction loss
- At higher speeds or on long, curvy roads, on-demand systems can struggle to keep pace with changing conditions
- Power-splitting mechanisms are often limited to helping with initial acceleration, not sustained control
Subaru's full-time approach eliminates these weaknesses. Power is always distributed to all four wheels, so the system is ready the instant conditions change. Less power is sent to each individual wheel compared to FWD or part-time AWD, reducing the likelihood of slip. The result is inherently better balance, safety, and confidence-inspiring performance.
Tailored Systems for Every Driving Style
Subaru doesn't rely on a one-size-fits-all approach. The brand offers multiple Symmetrical AWD configurations, each tuned to match the characteristics of the vehicle and driver:
Viscous-Coupling Centre Differential AWD (Manual Transmissions):
Maintains a 50/50 front/rear torque split with a viscous-coupling limited slip centre differential for optimum torque distribution and neutral handling.
Active Torque Split AWD (Lineartronic CVT Models):
Uses a multi-plate transfer clutch to maintain a 60/40 front/rear torque split, automatically adjusting on-the-fly for more predictable handling. Prioritizes ease of operation, fuel efficiency, and reliability.
Variable Torque Distribution AWD (WRX with SPT):
Adjusts front/rear torque split from 45/55 in normal conditions (for a sportier rear-biased feel) up to 50/50 when traction deteriorates, delivering performance and efficiency simultaneously.
Integrated Safety: VDC and AWD Working Together
Subaru Vehicle Dynamics Control (VDC) enhances the Symmetrical AWD system by monitoring wheel speed, steering position, yaw rate, and lateral acceleration. If sensors detect the vehicle isn't moving in the intended direction, VDC corrects the situation by adjusting torque split, applying brakes to individual wheels, and modulating engine output.
Because all four wheels are connected to a full-time AWD system, any wheel that loses traction regains it more quickly than on FWD or part-time AWD vehicles. This seamless integration ensures greater control and active safety without heavy-handed intervention that reduces driver engagement.
