Subaru has surprised the automotive world by unveiling its STI prototype at the Tokyo Auto Salon, indicating the return of the WRX STI in a slightly different form. Although Subaru previously announced the end of the gas-powered WRX STI, this new prototype aims to reignite fans’ excitement. However, there’s a significant twist—this model does not include the iconic manual transmission.

Instead, Subaru has taken a more modern approach by equipping the WRX STI S210 with a “Subaru Performance Transmission,” a continuous variable transmission (CVT). Coupled with an all-wheel-drive system and an upgraded version of the 2.4-litre turbocharged flat-four engine, the S210 delivers 296 horsepower and 277 lb-ft of torque—an increase over the standard WRX’s 271 horsepower and 256 lb-ft of torque. While it’s a commendable increase in power, it’s still a step back compared to the previous STI S209, which produced 341 horsepower and 330 lb-ft of torque.

In addition to the powertrain changes, Subaru has introduced a variety of performance enhancements to keep the S210 sharp. The prototype features additional bracing, S210-specific adaptive dampers, coil springs, and 19-inch BBS forged wheels shod with Michelin Pilot Sport 4S tires (255/35R-19). To accommodate the increased performance, the car is fitted with Brembo brakes, including six-piston callipers at the front featuring red accents and upgraded pads. The S210 also showcases distinctive styling elements such as a unique mesh grille, an S210 badge, red trim along the lower edge, and a more aggressive front bumper with vertical lighting elements and a lip spoiler. The subtle rear wing completes the performance aesthetic.

Inside the cabin, Subaru has equipped the S210 with carbon-fiber-backed Recaro seats, now featuring power adjustments—an unusual choice given the car’s performance focus. The rest of the cabin resembles the regular WRX, but with premium touches like microsuede-wrapped armrests and piano black trim on the dash and doors. And, of course, several S210 badges serve as reminders that this is not your average WRX.

Subaru has confirmed that only 500 units of the S210 will be produced, making it an extremely limited edition. However, it remains unclear whether any units will reach markets outside Japan. The company has also announced that pricing will be revealed at a later date, but anticipate it to be higher than the previous S209, which retailed for approximately $64,880 in the U.S.

While the absence of a manual transmission has disappointed some enthusiasts, Subaru’s decision to prioritize the CVT aligns with the preferences of the Japanese market, where automatic transmissions prevail. Nevertheless, fans of the WRX STI legacy can take solace in the fact that the STI badge is making a comeback—though with some adjustments to modernize the performance car for today’s market.

This new STI is set to be a Japan-exclusive release, arriving this autumn. Given its limited production and unique features, the S210 will likely carry a higher price tag than its predecessors. While it may not be the high-revving, manual-only sports sedan that many enthusiasts anticipated, the STI S210 still holds a special place for Subaru fans, offering a blend of aggressive styling, modern performance features, and the return of the legendary STI nameplate.
