Subaru recently unveiled a vehicle in Japan called the WRX STI Sport# Prototype, drawing widespread attention. Although the car closely resembles the production-ready WRX STI—featuring large-diameter wheels and signature red accents, appearing nearly complete—Subaru has clearly stated that it remains a concept car and not the long-awaited all-new production version of the WRX STI. Just a week earlier, the brand had fueled enthusiasts' expectations with multiple teaser videos hinting at an imminent STI production model, only to reveal merely a prototype showcase. Further details have yet to be disclosed, and the situation continues to develop.
