Although the internet got out ahead of them, the Subaru team just officially introduced the STI Performance Concept at the 2015 New York Auto Show. Created to be the ultimate road-ready version of the BRZ, this concept combines an aggressive body - complete with a large rear wing and flared wheel arches - with a turbocharged 2.0-liter boxer engine taken directly from the track-tuned BRZ GT300. Despite its aggressive stance, the STI Performance Concept benefits from a range of aero updates taken from the BRZ like new side skirts, a lowered suspension, and tweaks to the chassis, which combine with an upgraded engine cooling system for a look that is intimidating as it sounds. Specific power stats aren't available, but its track-ready kin can hit 300 bhp and 330 lb-ft in torque without breaking a sweat. Despite all the buzz, there's no word yet from Subaru on if this will be moving toward production anytime soon, but they did commit toward expanding the STI-enabled line in the States is definitely in the works.
