2015 Subaru WRX STI Interior. The 2015 Subaru WRX STI carries its bold personality inside, where new Alcantara seating surfaces accented by red and black leather bolsters and red stitching set the tone for the upgraded and roomier cabin. A driver-focused interior remains integral to the WRX STI performance character, with the new model debuting a motorsports-inspired flat-bottom steering wheel and new whiplash-reducing performance-design front seats with height and tilt-adjustable head restraints. A wide array of new user technologies include, for the first time in a Subaru WRX STI, availability of a harman/kardon® premium audio system.
2015 Subaru WRX STI Exterior. A bolder front design makes the 2015 WRX STI look ready to devour the road. The “nose-cone” configuration combines the grille and bumper cap into one unit ahead of the hood, which for the 2015 model is made from aluminum to reduce weight over the front of the car. Narrower headlights, designed to evoke a raptor’s stare, flank the Subaru hexagonal grille. It’s a more powerful stare thanks to new standard LED low-beam headlights.
The special hood, fenders, doors and quarters, bumpers, headlights and taillight clusters convey the Subaru WRX STI identity. As on previous WRX STI models, a functional hood scoop supplies the intercooler with fresh air, and in the 2015 model it is set more deeply into the hood to provide better forward visibility.
Other new performance-oriented details include foglight surrounds with a carbon fiber-like pattern and front fender vents that feature a mesh screen. A full aerodynamic body package includes the large trunk spoiler that has been a WRX STI signature feature. A rear diffuser, LED taillights and LED center high-mount stop lamp (CHMSL) leave a distinctive signature.
2015 Subaru WRX STI Engines and Transmission. The 2015 Subaru WRX STI is powered by a 2.5-liter turbocharged/intercooled 4-cylinder BOXER engine that employs the Dual Active Valve Control System (Dual AVCS). The engine, which is exclusive to the STI model, produces 305 horsepower (SAE) at 6,000 rpm and 290 lb.-ft. of peak torque at 4,000 rpm.
The WRX STI engine is teamed exclusively with a specially reinforced 6-speed manual transmission, which includes an STI short-throw shifter in the Launch Edition model.
