The 2011 Subaru Impreza WRX STI S206 NBR Challenge Package was released by Subaru Tecnica International with a limited number of 300 to be sold through Subaru dealerships in Japan. The NBR Challenge Package was released to commemorate the class win at 24 Hours Nürburgring endurance race held in June.

Named as the “crown of STi tuned cars” it comes with a lot of extra performance additions especially designed for the S206 NBR to make it handle even better than the already great handling of the WRX STI. It comes with an exclusively-made engine with the weight balance between piston, connecting rod, and crankshaft is optimized to enhance the rev feel.

Other additions include a ball bearing turbocharger with an upgraded ECU (Engine Control Unit) with STI tuning. The engine now delivers 235kW "320hp" and 431N.m "44kg.m" in maximum torque, all of which gives better accelerator response and with the low to mid range torque increased gives the WRX STi S206 NBR much superior driving capabilities.

On the exterior the NBR has received more exclusively made parts including a lower front spoiler, trunk spoiler, front fender outlet grille and side vents all for improvement of aerodynamics. The interior has more exclusively made parts including 'RECARO' racing bucket seats, and seatbelts and a genuine leather-wrapped steering wheel.
