- New generation of Subaru’s ultimate expression of the iconic, competition-bred WRX series combines 305-hp turbo BOXER engine and advanced Driver Controlled Centre Differential (DCCD) All-Wheel Drive system with newly enhanced chassis for wider performance envelope.
- Enhanced comfort with roomier cabin, upgraded materials and new user technologies.
Details / Performance
- Exclusive to WRX STI: 2.5-litre turbocharged BOXER engine produces 305 hp @ 6,000 rpm and 290 lb.-ft. peak torque @ 4,000 rpm.
- SI-DRIVE engine performance management with Intelligent, Sport and Sport Sharp settings.
- 6-speed manual transmission with triple-cone synchronizers on 1st and 2nd, double-cone on 3rd gear; improved for lower noise and vibration and easier shifting effort for 2015 model.
Chassis
- New body structure makes greater use of high-tensile steel than the previous model and features special stiffening elements at key locations.
- Inverted-strut front suspension with forged aluminum-alloy lower A-arms with pillow ball-type rear bushings.
- New Active Torque Vectoring, an enhancement of the Vehicle Dynamics Control (VDC) system, allows for improved cornering speeds and handling; in certain cornering situations, system can apply braking to inside front wheel for neutral steering.
- Multi-mode Vehicle Dynamics Control (VDC) allows driver to select level of stability and traction control intervention, or turn it off.
- Subaru’s proven ring-shaped reinforcement frame body structure has been shown to excel in the new small overlap test by the Insurance Institute for Highway Safety (IIHS).
- STI high-performance sport-tuned suspension.
- 18x8.5-in. cast alloy wheels; STI Sport-tech has 18x8.5-in. BBS forged alloy wheels.
- 245/40R18 summer performance tires.
- Brembo performance brake system employs ventilated 4-wheel disc brakes with 4-piston calipers in front and dual-piston calipers in the rear. Combination of Electronic Brake-force Distribution (EBD) and super sport Anti-lock Braking System (ABS) helps to enhance stability under hard braking.
Design
- 25 mm longer wheelbase than the previous WRX STI yields roomier interior.
- Aero-enhanced body design; hood, fenders, doors and quarters, bumpers, headlights and taillight clusters express WRX STI identity.

Symmetrical All-Wheel Drive
- Symmetrical All-Wheel Drive system with Driver Controlled Centre Differential (DCCD) with three automatic performance modes, in addition to six manual differential locking control settings. Normal torque split is 41:59 for handling agility; mechanical limited-slip type centre differential augments electronically controlled differential.
- Helical gear-type limited-slip front differential and TORSEN torque-sensing limited-slip rear differential.
