SYMMETRICAL ALL-WHEEL DRIVE
Stability reassures on the road. But stability also offers agility that excites and inspires confidence. Subaru vehicles are gifted with a superior ability to put you in charge behind the wheel, thanks to the inherently stable design of Symmetrical All-Wheel Drive, which features the SUBARU BOXER Engine. The unique design of this system efficiently delivers power to all four wheels at all times for enhanced control on all roads and in poor conditions. It also allows the main components to be aligned longitudinally for excellent side-to-side balance and handling precision. What’s more, it creates a low centre of gravity for engaging responsiveness. The unique advantages of Symmetrical All-Wheel Drive make for exceptionally rewarding handling and empower you to better avoid danger.

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.
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.
Years of heated competition, extensive testing and advances in materials and engineering, have combined to inspire chassis designs for the WRX and 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.
Subaru Intelligent Drive (SI-DRIVE) lets you adapt the driving character of the WRX or the WRX STI to your needs or desires. Whilst in Intelligent Mode [I], acceleration is smooth with an eye toward optimal efficiency. Select Sport Mode [S] for linear response, and versatile command of every condition. To extract the maximum response from the turbocharged engine, switch to Sport Sharp Mode [S#]. It gives you the most direct throttle response and precise rev control across the entire rpm range.
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.
