Subaru said the Subaru Impreza WRX STI Spec C, a new addition to the current WRX STI line-up would go on sale today through Subaru dealerships in Japan.
The WRX STI Spec C model features enhanced engine and chassis performance as well as a lighter body on the premise of driving in motor sports.
Power is up to 227kW at 6400rpm and torque is increased to 422Nm at 4400rpm. The standard STi produces 221kW and 407Nm.
Subaru Japan says the model further strengthens the WRX STi’s presence in the high performance car arena by offering sheer excitement and unique driving sensations as a distinctive road sport model, in line with the performance level originally delivered by the Impreza WRX STI.
Among the enhancements are a ball-bearing mount for the twin-scroll turbocharger axle and exclusive retuning of the ECU to give the engine of the spec C model quicker response and improved accelerating performance.
Thanks to its specially designed front & rear suspensions and improved body rigidity, the chassis offers stable and linear driving control even in marginal driving conditions.
The adoption of an aluminium bonnet, laminar window glasses and a downsized battery resulted in a lighter overall weight, which further polishes the model’s driving performance.
As a result of changes to the ECU programming, the engine offers smoother and quicker response to the accelerator pedal.
Subaru has also made changes to the fuel pump to provide stable fuel delivery even on high-load driving.
It probably won’t make any difference to the performance but gold coloured “Brembo” brake callipers are standard.
The front bucket seats (fabric with red stitch) are standard on models with 18-inches alloy wheels, while Recaro seats (Alcantara and leather combination with red stitch) are optional.
There are two exclusive exterior colors, Sunrise Yellow and Pure White, and production is limited to 900 units.
