Subaru has ignited excitement among automotive enthusiasts with the unveiling of the WRX S210 STI Complete Car prototype at the 2025 Tokyo Auto Salon. This exclusive model offers a glimpse into a limited production run of just 500 units, slated for release later this year, and promises enhanced performance despite Subaru’s current stance on a new generation WRX STI.
While Subaru has officially stated there are no plans for a traditional STI version of the latest WRX generation, the introduction of the Subaru Wrx Sti S210 signals a different approach. This prototype, showcased at the prestigious 2025 Tokyo Auto Salon, represents a high-performance variant developed by Subaru Tecnica International (STI), Subaru’s renowned motorsports division. The WRX S210 STI is not just a concept; it’s a preview of a production model, limited to 500 examples, primarily intended for the Japanese market.
Subaru has previously catered to enthusiasts in Japan with WRX S4 STI Sport models, which offer subtle performance and aesthetic upgrades. However, the WRX S210 STI marks a significant step up, promising power figures reminiscent of classic WRX STI models. The heart of the Subaru WRX STI S210 is a meticulously tuned turbocharged 2.4-liter flat-4 engine. This enhanced powerplant is engineered to deliver a targeted output of 296 horsepower, a notable increase over the standard WRX’s 271 horsepower. This power boost positions the S210 as a more potent and exclusive offering within the WRX lineup.

A significant departure from STI tradition is the Subaru WRX STI S210’s transmission. For the first time in an S-series WRX, power is managed through a CVT (Continuously Variable Transmission) system, sending power to all four wheels. This contrasts with the manual transmissions typically associated with high-performance STI models and marks a strategic shift for this limited edition. Complementing the powertrain enhancements are substantial chassis and aesthetic upgrades. The WRX STI S210 rides on 19-inch STI wheels, wrapped in high-performance 255/35 Michelin tires, ensuring optimal grip and handling. Braking performance is elevated with a Brembo brake package featuring robust six-piston calipers at the front, providing exceptional stopping power. Aerodynamic enhancements, honed on the track, further refine the vehicle’s stability and performance at higher speeds. Inside the cabin, the driver and passenger are treated to Recaro bucket seats, constructed with lightweight carbon-fiber shells and offering eight-way adjustability, blending comfort and support for spirited driving.
While the Subaru WRX STI S210 offers a compelling package for enthusiasts, it arrives in a landscape where the future of the WRX STI nameplate remains uncertain. However, independent initiatives like the WRX by Prodrive, developed by the renowned British motorsports firm Prodrive, demonstrate the enduring appeal and potential for high-performance WRX variants. Prodrive’s interpretation of a next-generation WRX STI has fueled speculation and hope that such performance enhancements might eventually become accessible to a broader market.
Beyond the WRX STI S210, Subaru’s presence at the Tokyo Auto Salon also highlighted its broader commitment to performance and innovation. The display included a Crosstrek Hybrid equipped with STI parts, showcasing STI’s influence across Subaru’s model range. Furthermore, the presence of a BRZ GT300 race car, prepared for the 2025 Super GT series, and a WRX race car concept designed for sustainable fuel, underscored Subaru’s dedication to both motorsport and future-oriented automotive technologies. The Subaru WRX STI S210, therefore, stands as a testament to Subaru’s ongoing passion for performance, even as it navigates evolving market demands and technological advancements.
