Subaru has finally unveiled a true Subaru Tecnica International (STI) version of the WRX, breaking its nearly three-year stance that such a model would not be possible. The 2025 WRX STI S210 debuted at the Tokyo Auto Salon, marking a significant shift in the brand’s approach. Subaru previously cited stricter emissions regulations as the reason for shelving the idea, but it seems the tide has turned for fans of the performance-oriented sedan.

The S210 is a proper Subaru Tecnica International creation, described by the company as “the pinnacle of STI complete cars.” It is based on the Japanese Domestic Market (JDM) WRX S4 STI Sport R EX but comes with several performance upgrades. Its 2.4-liter turbocharged gasoline engine has been reworked to deliver 296 horsepower and 277 pound-feet of torque. While this represents a boost of 25 horsepower and 19 pound-feet of torque over the standard WRX in the United States, it still falls short of the 341 horsepower and 330 pound-feet of torque offered by the S209 that was launched in 2019.

Unlike the S209’s six-speed manual transmission, the S210 features the Subaru Performance Transmission, a continuously variable transmission (CVT) that Subaru has branded with an exciting name. The added power comes from a revised exhaust system, optimized intake ducts, and updated engine control unit (ECU) tuning. Maximum power is achieved at 5,700 revolutions per minute, with peak torque available from 2,000 revolutions per minute.

The upgrades extend beyond the engine bay. The S210 rides on 19-inch BBS forged wheels paired with Michelin Pilot Sport 4S tires and features front Brembo brakes, electronically controlled dampers, and a transmission fluid cooler. The exterior is enhanced with a carbon fiber rear spoiler and black accents, giving it a sportier and more aggressive look.
Inside, the sedan features eight-way adjustable Recaro carbon bucket seats, red seatbelts, and plenty of piano-black trim. A serial number plate confirms its exclusivity, as only 500 units will be produced. Subaru plans to open orders this spring, and although pricing has not been revealed, the rarity and extensive upgrades suggest the S210 will carry a premium price tag.
