Subaru has unveiled a limited edition WRX STI at the 2015 Tokyo Motor Show today. The WRX STI S207 special edition is limited to just 400 units and will be sold exclusively in Japan.
While the standard WRX STI is powered by a 2.5-litre turbocharged boxer engine, the WRX STI S207 receives a 2.0-litre turbo boxer specially tuned to produce 241kW at 7,200rpm and 431Nm of torque from 3,200 to 4,800rpm.
Liberating the extra 20kW and 24Nm over the regular WRX STI is a new ECU tune, reworked twin-scroll turbocharger and high-flow performance exhaust muffler. The extra punch is managed by a reworked vehicle dynamic system and torque vectoring calibration.
Much more than raised performance figures, the WRX STI S207 also gains Bilstein suspension, various chassis strengthening bits and an even quicker steering-gear ratio of 11:1. Stopping power is improved through uprated Brembo brakes with six pot calipers at the front and four pot calipers at the rear, all acting on larger cross-drilled rotors.
The WRX STI’s already aggressive looks move up a notch with red accents on the front grille and rear diffuser, a front lip spoiler, side skirt extensions and air breathers behind the rear wheel arches. There’s also a full dry carbon fibre rear spoiler, complemented by STI-designed BBS 19-inch gloss black forged alloy wheels wrapped in 255/35R19 tyres.
Inside, the S207 edition differentiates with a new instrument panel, engine start button, shift knob and gloss red trim on the dashboard. A pair of striking Recaro leather racing bucket seats further highlight the limited edition model’s serious performance potential.
The WRS STI S207 is available in Crystal Black Silica, Crystal White Pearl or WR Blue Pearl paint job. The Japanese carmaker has also allocated 100 units for a “special edition” of the special edition – the NBR Challenge Package Yellow Edition, which comes exclusively in Sunrise Yellow paintwork garnished with black mirror caps, side sill moldings and yellow side sill plates with the “S207” logo.
