The STI Performance Concept debuted at this year's New York Auto Show as an early step in STI's attempt to expand its reach here. The BRZ-derived coupe featured a body with a ground-scraping front bumper, tweaked headlights, wider fenders, a massive rear wing, and diffuser with a center-exit exhaust. All of these elements also show up on the patent renderings.
The concept was just as exciting under the hood because STI installed a 2.0-liter, turbocharged boxer four-cylinder from its GT300 racer, and upgrades for the chassis, suspension, and brakes came from the Japanese market's BRZ tS. While the coupe made hearts race, the company was clear it didn't necessarily plan to build the model.
Patent filings aren't a guarantee for production, and even if this one does arrive in showrooms, it might not come to the US. That's because Subaru and Toyota have a history of creating Japan-exclusive versions like the tS or Style Cb. That being said, spy shots have revealed a camouflaged GT86 testing in Europe, and rumors indicate more power from the engine. Subie's boss has even confirmed the existence of a partnership to create a next-gen model.
