Symmetrical All-Wheel Drive (AWD)

Symmetrical All-Wheel Drive (AWD)

Providing a driving experience that’s safe and also enjoyable is the top priority of Subaru engineers. That’s why almost every Subaru vehicle comes equipped with Symmetrical All-Wheel Drive as a standard feature. For the utmost confidence and control, there’s simply no substitute. Every day on the road presents unexpected conditions and unexpected events, and Symmetrical All-Wheel Drive helps drivers cope with these challenges by distributing torque to all four wheels, providing traction where front- or rear-wheel-drive cars falter. Whenever you’re driving a Subaru equipped with Symmetrical All-Wheel Drive, rest assured you’ll have peace of mind and confidence wherever you go.

Sport-Tuned Chassis

Years of heated competition, extensive testing and advances in materials and engineering, have combined to inspire chassis designs for the WRX STI. Exceptional stability and lightning quick response were central to this development, as high-tensile steel was employed throughout the frame to increase its torsional rigidity and better control the vehicle’s weight. What’s more, the suspension was tuned to exacting standards with stiffer stabilisers, quicker spring rates, and improvements like stiffer pillow ball bushings. This expertly balances stiffness and compliance to create immediate response and an unprecedented connection between driver, car and the road.

Active Torque Vectoring

This technology helps make handling more precise, whilst allowing you to push your vehicle closer to the limit. As you enter a corner and lateral g-forces take hold, the system can route power to select wheels to help you keep your intended line. This means your WRX STI responds to your steering input more immediately and more engagingly.

For instant, seamless response to changing conditions, the Lineartronic CVT (Continuously Variable Transmission) uses a chain instead of a belt—allowing a greater span of overall ratios for improved performance and efficiency as well as a faster response to throttle input. It’s longitudinally paired with an active torque-split AWD system that responds to traction conditions, the transmission and driver inputs by continuously controlling the torque distribution front to rear.

Multi-Mode DCCD

The Driver’s Control Centre Differential (DCCD) allows you to dial in the centre differential locking of the WRX STI and thereby shape its handling. It adjusts both an electromagnetic multi-plate transfer clutch and mechanical locking of a Limited Slip Differential (LSD) to apportion the torque to the front and rear wheels.

Auto Mode finds the ideal power distribution for changing conditions, whilst Auto [+] keeps more power up front for increased traction. Auto [-] puts more power to the rear for tighter cornering, and the six-step Manual Mode lets you lock in your preferred handling characteristics.

SUBARU BOXER Engine

Few motors have the same reputation for pure excitement on any road as the 2.5-litre turbo of the WRX STI. It flawlessly fuses raw power with total poise as its turbo spools almost instantaneously and unleashes power for intense acceleration. Proven over the years, its performance has been made only more thrilling in the WRX STI.
