In front, the 2011 WRX STI models feature sharpened bumper corners and wider, blacked-out fog lamp nacelles to accentuate the “wide and low” profile. A jutting lip spoiler with three-dimensional detailing emphasizes the cars’ sporty intent. The newly designed front grille with black base and blacked-out Subaru wing highlights the headlights’ shape to give the entire front end a more powerful appearance, accentuated by larger grille and bumper intake openings.
New standard 18-inch aluminum wheels feature high-luster paint and weigh 17.6 lbs. less than the previous standard wheels. The optional 18 x 8.5-in. BBS® forged aluminum-alloy wheels, which further reduce unsprung vehicle weight, are highlighted by silver high-luster paint for 2011.
Exclusive to the Subaru Impreza WRX STI, the Brembo Performance Brake System uses ventilated 4-wheel Super Sport anti-lock (ABS) disc brakes with Electronic Brake-force Distribution (EBD). Super Sport ABS can control the braking forces at each rear wheel independently, which optimizes braking ability during hard cornering to help reduce understeer.
The 2011 WRX STI continues as the ultimate-performance Subaru with its high-boost 305-hp turbocharged/intercooled 4-cyl. Boxer engine and 6-speed manual transmission. The STI also features Multi-Mode Driver Controlled Center Differential (DCCD) version of Symmetrical All-Wheel Drive with three “Auto” modes, as well as a manual mode with six driver-selectable differential locking settings.
New for 2011, the WRX STI interior is finished in black and silver to highlight its sporty design. Trim panels, the steering wheel air bag cover and steering wheel switches are now dark cast metallic. The 2011 Subaru Impreza WRX STI models arrive in Subaru dealerships in late summer 2010.
