2011 Subaru Impreza WRX STI Spec C
Subaru has now announced a new 2011 model year version that will go on sale in Japan later this month.
The car’s twin scroll turbocharger gets newly adopted ball bearings for the turbine axle bearing, and the ECU program was also exclusively tuned. Thus the engine of the spec C model increases the maximum torque, and provides quicker response and improved accelerating performance. Peak output now stands at 304 horsepower and 317 pound-feet of torque.
The adoption of an aluminum engine hood, laminar window glasses and a downsized battery resulted in a lighter body, which further refines the model’s driving performance. These include reinforcement of the cross member in front-suspension and the addition of a mechanical type limited-slip differential rather than a Torsen type in the rear.
Additionally, thanks to its specially tuned front and rear suspension, the chassis offers improved handling, especially in the wet. Also new are a set of 245/40R18 Bridgestone Potenza tires.
