At the Tokyo Motor Show, Subaru Tecnica International (STI) has pulled the covers off of a special-edition WRX STI, designated the S207. With just 400 units to be produced, starting December 1, the S207 begins as a WRX STI model, then receives several STI-designated upgrades, including exclusive engine and suspension tuning along with unique design elements inside and out.

Set to be the supercar pinnacle of the Subaru lineup, engine tuning sees the power output of the S207 increased to 328 PS (323.5 hp, 241 kW) and the well-established all-wheel drive of the WRX is enhanced by a front-to-rear center differential control.

The engine in the STI S207 also receives a new electronic control unit, a twin-scroll ball bearing turbocharger, and a strengthened silicon intake duct. The exhaust system sees a lower back pressure from an exclusive performance muffler and exhaust piping.

A new front suspension with adjustable damping has been added, using Bilstein DampMatch II struts in a flexible tower bar. A steering ratio of 11:1 tightens turning response for sharper cornering, which is further augmented by electronic Active Torque Vectoring that has seen tweaks to its programming to match the S207’s improved performance.

Brembo 6-pot brakes in front (4-pot in the rear) feature a monoblock opposed-piston caliper design and drilled rotors, while the wheels are clad in exclusive 92Y Dunlop Sport Maxx RT tires.

The exterior of the WRX STI S207 has an exclusive front spoiler, front grille, and rear-bumper air outlet, with specialized badging denoting the car’s provenance. Inside, STI-specification Recaro front seating and customized sport instruments accent the S207’s exclusivity.

A special NBR Challenge Package will be an option for the S207, limited to 200 units, as a tribute to the Nurburgring 24-Hour Race. This comprises an exclusive dry carbon rear spoiler and an ornament that celebrates the company’s victory in the SP3T class at the Nurburgring 24 Hours this year.

Three special body colors will be offered for the vehicle, including World Rallycross Blue Pearl, Crystal White Pearl, and Crystal Black Silica. Additionally, 100 of the 200 units in the NBR Challenge Package will have a special Yellow Edition in Sunrise Yellow to further celebrate the winning race car at Nurburgring.

The manufacturer’s recommended retail prices for the STI S207 begin at ¥5,994,000 (US$49,700) with consumption tax. The NBR Challenge Package will begin at ¥6,318,000 (US$52,400) and the special Yellow Edition at ¥6,372,000 (US$52,800). The Subaru WRX STI S207 will not be offered outside of Japan.
