Subaru Canada, Inc. (SCI) is pleased to announce pricing for the 2011 high-performance Impreza WRX and WRX STI models.In addition to the new styling, the 2011 WRX STI features significantly revised suspension tuning and lighter 18-inch wheels for even sharper handling.“The 2011 4-door WRX STI will expand the appeal of this iconic performance model to a wider range of driving enthusiasts.”

The 2011 Impreza WRX STI models are en route to Subaru dealerships now.

New WRX STI Four-Door with Wide-Body Design
The 2011 WRX STI continues as the ultimate-performance Subaru with its high-boost 305-horsepower turbocharged/intercooled Subaru Boxer engine teamed with a 6-speed manual transmission and the exclusive Multi-Mode Driver Controlled Centre Differential (DCCD) version of Subaru’s Symmetrical Full-time All-Wheel Drive system.
The WRX STI is equipped with advanced dynamic control systems, including Subaru Intelligent Drive (SI-DRIVE) and a Multi-Mode Vehicle Dynamics Control (VDC) system, which features a track performance-optimized mode.

All-New 4-Door Wide Body Design for 2011

Like the wide-body design already used for the 5-door WRX STI, the new 4-door WRX STI features the widened front and rear track dimensions of the 5-door model and wider, more pronounced front fenders and rear quarter panels. In front, the 2011 WRX STI models feature sharpened bumper corners to accentuate the “wide and low” profile. A striking high profile rear spoiler was exclusively designed for the STI 4-door.

New WRX STI Chassis Tuning for 2011

The Subaru WRX STI was already a highly optimized performance machine. The WRX STI delivers responsive handling along with everyday ride compliance. Aluminum front lower L-arms reduce unsprung vehicle weight.

Both the front and rear suspension systems employ higher-rate springs and thicker front and rear stabilizer bars than the 2010 model: 21 mm vs. 20 mm in front and 19 mm vs. 18 mm in rear. New standard 18-inch Enkei aluminum wheels feature high-luster paint and weigh 8kg less than the previous standard wheels.

SI-DRIVE Gives WRX STI Driver More Control

SI-DRIVE alters vehicle performance characteristics by regulating the Engine Control Module (ECM) and by fine-tuning the Electronic Throttle Control system.

Multi-Mode DCCD All-Wheel Drive with Three-Mode Vehicle Dynamics Control

As before, the 2011 WRX STI is exclusively equipped with the Multi-Mode Driver Controlled Centre Differential (DCCD) version of Subaru Symmetrical All-Wheel Drive. A mechanical limited-slip type centre differential augments an electronically controlled centre differential to enhance torque transfer performance. Sensor inputs that include steering angle, throttle position, RPM, lateral g, yaw, brake, ABS and wheel speed govern torque transfer response. A helical-type limited-slip front differential and a TORSEN(R) torque-sensing limited-slip rear differential optimize side-to-side power distribution, helping to prevent the inside wheels from slipping during cornering.

The DCCD AWD system features three automatic modes. The Vehicle Dynamics Control (VDC) stability and traction control system is standard on all Subaru models. Exclusive to the WRX STI, the Multi-Mode VDC system offers the driver three settings: VDC Normal, Traction and Off. Also exclusive to the WRX STI, the Brembo Performance Brake System uses ventilated 4-wheel disc brakes with Super Sport anti-lock (ABS) and Electronic Brake-force Distribution (EBD). The wheel features control switches for Bluetooth(R) hands-free phone function. The WRX STI models are equipped with standard aluminum-alloy pedals and driver’s footrest. Performance-design front seats integrate the backrest and head restraint into a single structure. A 60/40-split folding rear seat further boosts cargo capacity and convenience, and the 4-door also features a rear seat fold-down centre armrest.

Steering wheel mounted controls for the audio system, cruise control and Bluetooth(R) are standard for all 2011 Impreza WRX STI models.

Subaru Safety
Electronic Brake-force Distribution (EBD) provides precise control of braking pressure between the front and rear wheels based on the vehicle load to improve stability and stopping distances. All Impreza models utilize the proven advanced Subaru Ring-Shaped Reinforcement Frame body structure with front and rear crumple zones. Front seat side airbags and side-curtain airbags are standard on all Subaru models.
