Subaru Impreza WRX STi Overview

The WRX STi sits atop the Impreza line. This is the one most coveted by hard-core driving enthusiasts, and it's distinguished by a huge two-step rear wing and even more aggressive bodywork. More important, it's powered by a crazy-fast 300-hp version of the boxer four, with even firmer suspension and track-style Brembo brakes. Safety features include dual front airbags, front side-impact airbags, and seatbelts with pre-tensioners and force limiters for the front seats. ABS comes standard and features four sensors and four channels. Electronic brake-force distribution also allows for better emergency braking.

For 2006, the Subaru Impreza models have been restyled front and rear. The body structure has been improved and the suspension refined. There's more standard equipment, more safety equipment, and more new technology.
