The S210 is officially considered a legitimate Subaru Tecnica International vehicle and "the pinnacle of the STI complete cars." Based on the JDM-spec WRX S4 STI Sport R EX, the Japan special has had its 2.4-liter turbocharged gasoline engine massaged for more power. It now makes 296 hp and 277 lb-ft (375 Nm) of torque, giving it an advantage of 25 hp and 19 lb-ft (26 Nm) over the regular WRX we get in America.
The S210 gets its extra oomph from an upgraded exhaust system and different intake ducts. Engineers also tweaked the ECU of the boxer engine, which pumps out full power at 5,700 rpm and peak torque from 2,000 rpm. Elsewhere, it gets 19-inch BBS forged wheels with 255/35R19 Michelin Pilot Sport 4S tires, front Brembo brakes, electronically controlled dampers, and a Subaru Performance transmission fluid cooler.
Beyond the mechanical changes, the sports sedan has an aerodynamic body kit with a carbon rear spoiler and black accents. Inside, there are eight-way Recaro carbon bucket seats, red seatbelts, plenty of piano-black surfaces, and a serial number plate to remind you it's not a run-of-the-mill WRX but an actual STI.
Subaru is only making 500 cars and will open the order books this spring. Pricing hasn't been disclosed, but the S210 certainly won't be cheap, given its many upgrades and rarity.
