The Subaru WRX STI has numerous limited and special track editions that were exclusive to Japan, such as the WRX STI S207 and WRX STI S208. For the first time ever, Subaru has released a WRX STI S209, and this time, it’s exclusive to the North American market. Not only that, but the S209 is the most powerful Subaru ever released.
For starters, the WRX STI’s EJ25 2.5-liter H4 turbocharged boxer engine now produces 341 hp and ten percent higher mid-range torque at 3,600 rpm. This is the result of numerous modifications that range from lighter forged pistons and connecting rods, high-flow intake with an intercooler water spray system, larger fuel injectors, high-performance mufflers, bigger hand-polished stainless-steel exhaust tips, and an STI-tuned engine control module. An HKS turbocharger with a larger turbine and compressor, as well as an increased boost pressure of 18.0 psi (16.2 psi for the standard WRX STI) round up the extensive modifications made in the WRX STI S209’s powertrain.
Power is sent exclusively through the Symmetrical AWD system via a close-ratio 6-speed manual transmission. Managing the way the car moves around through corners are a set of Bilstein dampers, stiffened coil springs, a 20 mm rear stabilizer bar, as well as pillow-type bushings for the front and rear lateral links. These are upgrades derived from the WRX STI Nurburgring Challenge race car. Along with the 19×9-inch forged BBS alloy wheels wrapped in 265/35 Dunlop SP Sport Maxx GT600A developed specifically for the S209, the car’s maximum lateral grip has been increased to over 1.0 g.
Styling-wise, the S209 has wider fenders in order to accommodate the wider front and rear tracks, which are 15 mm wider both at the front and rear. Stopping power comes courtesy of of Brembo brakes featuring cross-drilled steel rotors and 6-piston mono-block front calipers and 2-piston mono-block rear calipers. There are also front bumper canards, carbon fiber roof, and carbon fiber rear wing. Inside, there’s a flat-bottom steering wheel, Recaro bucket seats, S209 badging and an S209 serial number plaque on the center console.
Only 200 units will be sold in two color choices. The WR Blue Pearl comes with gray wheels, while the Crystal White Pearl comes with gold wheels. The S209 will go on sale in late 2019 with pricing to be announced soon.
