    SUBARU BOXER Engine

    While the 2.5-litre turbocharged SUBARU BOXER engine generating 221 kW and 407 Nm of torque provides electrifying acceleration, driving performance isn't just about numbers. That's why the WRX STI was revamped to enhance overall driving feel. The WRX STI is more communicative, more responsive, and more exciting to drive in many situations.

    SUBARU BOXER ENGINE

    Why SUBARU BOXER Engine?

    The boxer engine derives its name from the horizontal movement of its pistons, which resembles the quick, jab-like motions of a boxer's fists. Although not a global standard, Subaru remains solely committed to the SUBARU BOXER engine because it embodies the Subaru promise of delivering enjoyment and peace of mind to all passengers. It also represents our steadfast commitment to technological innovation and engineering excellence.

    SUBARU BOXER TRAITS

    In-line EngineSUBARU BOXER EngineV-type Engine

    What makes it unique?

    Unlike traditional “in-line” or “V-type” engine configurations, the pistons’ opposing movements inherently counteract each other, naturally helping to reduce vibration without the need for counter-balancers, which add weight and complexity.

    Sport-tuned Chassis

    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.

    Active Torque Vectoring

    Active Torque Vectoring

    This technology helps make handling more precise, while 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 or WRX STI responds to your steering input more immediately and more engagingly.

    Multi-mode DCCD

    …

    Multi-mode DCCD

    The enhanced Multi-mode Driver Controlled Centre Differential (DCCD) has been revamped for even better handling ability. It allows you to dial-in the centre differential locking of the WRX STI and thereby shape its handling. Thanks to chassis advancements, electronic control is now used over the entire operating range to apportion torque to the front and rear wheels. Auto Mode finds the ideal power distribution for changing conditions, while 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.

    SI-DRIVE

    SI-DRIVE

    Subaru Intelligent Drive (SI-DRIVE) lets you adapt the driving character of the WRX* or the WRX STI to your needs or desires. While 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.
