STI first Releases STI complete car “S210” Prototype in Japan
Subaru Corporation’s motorsport subsidiary Subaru Tecnica International Inc*1 has announced today, 10 January 2025, the S210, a model of the S series, the pinnacle of the STI complete cars, based on the WRX S4 STI Sport R EX.
Subaru Corporation’s motorsport subsidiary Subaru Tecnica International Inc*1 has announced today, 10 January 2025, the S210, a model of the S series, the pinnacle of the STI complete cars, based on the WRX S4 STI Sport R EX.
The S210 is a direct derivative model of the race car that competes on one of the world's toughest tracks, incorporating technology and knowledge gained from the Nürburgring 24-Hour Race*2 where STI takes on a challenge, and offers maneuverability that allows the driver to control the car at will.
The engine is based on the WRX S4's FA24, and a newly developed air cleaner, intake ducts and pre-turbo ducts for the intake system and for the exhaust system a low back pressure muffler with a newly developed large diameter tail pipe and an exhaust pipe rear with a cannonball shaped chamber have been introduced to reduce intake and exhaust resistance thoroughly. Also, with the ECU being specially tuned, this car delivers a maximum output of 300 hp (development target). The linear torque response to acceleration ensures the engine output characteristics which allow the driver to press the accelerator pedal with a sense of security and confidence in all situations.
This is the first S-series vehicle to feature the Subaru Performance Transmission. By tuning the gearshift characteristics to match the engine output characteristics, driving force characteristics with a high degree of controllability have been achieved. The result is an extremely heightened pleasure of driving as the driver's intentions are precisely transmitted to the car.
Around the suspension, the vehicle features Michelin 255/35R19 high-grip tires, STI Flexible Performance Wheels with specific shapes for front and rear, specially tuned electronic control dampers and coil springs, and newly developed rear stabilizer bushes. For the brakes, Brembo front 6-pot calipers, special brake pads as well as front and rear drilled rotors are combined. Together with specially tuned electric boosters, a braking system with excellent controllability has been realized.
In addition to STI's unique Flexible parts proven in the Nürburgring 24-Hour Race car, the body is fitted with aerodynamic parts such as the newly developed and STI Sport Side Garnish and STI Dry Carbon Rear Spoiler to regulate air flow and achieve high handling performance.
The seats are newly developed RECARO 8-way power seats with carbon backrests*3, providing a high degree of hold and comfort. The interior is based on black tones to offer a space where the driver can concentrate on driving, with red coloring added for effect, creating a special specification that gives the driver high expectations for driving and the pleasure of ownership.
The S210 STI Complete Car is limited to 500 units. The sales method will be announced in spring 2025.
