All 2006 Subaru Impreza WRX models get a new engine that puts out 230 horsepower at 5,600 rpm and 235 lb.-ft. of torque at 3,600 rpm. This 2.5-liter, turbocharged four cylinder features variable valve timing and maximum boost measuring 13.5 psi. In comparison, last year’s 2.0-liter engine provided 217 horsepower and 217 lb.-ft. of torque. Subaru officials claim that the new motor is more responsive off the line and provides additional mid-range torque. A five-speed manual transmission is standard; no other transmission is available.

Under the skin are revised suspension and steering systems that are featured on all 2006 WRX models. New aluminum-alloy lower control arms are added in front, and the steering ratio has improved to 15:1 rather than 2005’s 16.5:1. Subaru has also focused on braking, giving WRX models rear ventilated discs that are one inch larger than last year and painting the four-piston front and two-piston rear calipers. Antilock and electronic brake force distribution systems are standard.
