SYMMETRICAL AWD
Most all-wheel drive systems are compromises—add-ons bolted to fundamentally front-wheel or rear-wheel drive platforms. Subaru's Symmetrical AWD is different. It's engineered from the ground up with the drivetrain as the structural foundation. The horizontally-opposed boxer engine sits low and flat in the chassis. The transmission and driveshaft run in a perfectly straight line along the car's centerline. Equal-length halfshafts to all four wheels.
The result isn't just mechanical symmetry—it's dynamic balance. Weight distribution is near-perfect 50/50 front-to-rear. The center of gravity sits lower than in conventional inline or V-configuration engines. There's no torque steer, no understeer dominance, no rear-biased oversteer tendency. The GC8 STI goes exactly where you point it, every single time.
The driver-controlled center differential lets you adjust power distribution on the fly. Lock it 50/50 for maximum traction on gravel or snow. Bias it rearward for more rotation on tarmac. The system is mechanical, reliable, and infinitely adjustable. This is rally-proven technology refined for road use—engineering that wins championships transferred directly to production cars.
