Billed by Subaru as the "crown of STI tuned cars", the new Impreza WRX STI S206 follows on from previous “S” versions, such as the S203, S204 and S205.
So what's special about the new STI model? Well, for starters, the S206 employs exclusive Bilstein dampers, STi coil springs, a flexible front tower bar and draw stiffener, which promise to further improve the car’s precise and quick cornering response. The S206 rides on a new set of 19-inch BBS aluminum wheels, which have been designed exclusively for this model, and are shod in Michelin Pilot Super Sport tires.
Under the hood, STi’s engineers have further honed the flat-four turbocharged engine by optimizing the weight balance between pistons, connecting rods and crankshaft in order to enhance the rev feel.
And that's not all as the 2.0-liter unit also gains a retuned ECU, an enhanced twin-scroll turbocharger and a reduced-back pressure exhaust system, all of which help increase output to 320HP and 431 Nm ( 318 lb-ft).
Subaru also claims that the S206 has quicker throttle response and delivers more torque in low- and mid-range revs, offering better drivability.
A lower front spoiler and new grille, different side sills and a rear spoiler designed exclusively for the S206 help improve its aerodynamics as well as distinguish it from the regular STIs, while the exclusive leather steering wheel, Recaro bucket seats with red seatbelts and the STI designed push engine start switch round out the changes.
Subaru also developed a special NBR Challenge Package for the S206, commemorating the Japanese firm's class win at the Nürburgring 24 Hours endurance race.
It features a carbon-fibre roof and rear spoiler, plus Nürburgring Challenge sticker and red door sills, and will be available in 100 units - or rather it would have been available if all 100 cars hadn’t already been spoken for in Japan…
