At its simplest, all-wheel drive (AWD) means a vehicle can send torque to both the front and rear wheels. This contrasts with 2-wheel-drive systems, which power only the front or rear axle. By distributing engine output across all four wheels, AWD improves traction on slippery surfaces, such as wet roads, gravel, or light snow.

However, not all AWD systems are created equal. Some activate the rear wheels only when the front wheels begin to slip, introducing delays that can compromise control. Subaru’s solution remains active every moment, ensuring seamless engagement without waiting for wheelspin.^*

The Subaru drivetrain showcases five core elements neatly aligned, including:

1. SUBARU BOXER® engine: A flat, horizontally opposed design lowers the center of gravity, enhancing cornering agility.
2. Transmission: Power flows directly into the center differential, whether a Lineartronic® CVT (Continually Variable Transmission) or manual gearbox.
3. Center Differential: Continuously varies torque split between front and rear axles, responding to wheel slip and driver input in real time.
4. Front and Rear Driveshafts: Perfectly parallel to the vehicle’s centerline, these shafts channel torque to each axle with minimal friction.
5. Front and Rear Differentials: Each rear or front differential divides torque left to right, maximizing grip under all conditions.

Subaru reduces energy loss and ensures consistent, balanced performance by keeping these components in a straight, symmetrical layout.
