Both the 2. 5 i sedan and the Outback Sport are available in a Special Edition. which adds additional equipment including automatic climate control and an upgraded sound system with CD changer. The rally-inspired WRX gets a sport-tuned suspension. high-performance brakes. and larger 17-inch wheels to handle the turbocharged engine's extra power. The WRX models get a slightly different headlight and taillight design for this year. and inside. bolstered sport seats. aluminum pedal pads. and a leather-trimmed shift knob complete the package. Automatic climate control and an upgraded sound system with CD changer are standard on the WRX. Two other WRX models are offered. The WRX Limited brings more luxury equipment. including leather-trimmed heated seats. heated mirrors. a windshield de-icer. and a moonroof.

The top-performance STI. tuned by Subaru Tecnica International. the high-performance and motorsports division of Subaru's parent company. offers overall performance that rivals some of the world's top (and much more expensive) sports cars. The STI has a unique six-speed manual with carbon-plated synchronizers for the top gears. and a specially set-up version of Subaru's Symmetrical All-Wheel Drive system. The system's Driver Controlled Center Differential (DCCD) allows the opportunity to manually vary the split of power between the front and rear wheels. and a new mechanical limited-slip differential helps improve drivability and handling. STI visual cues include special ground effects. a roof vane spoiler and rear spoiler. underbody aerodynamic work. and wide-flare fenders. The STI also employs a Brembo high-performance braking system with Super Sport ABS. and the suspension is lowered nearly an inch compared to the WRX. There's also an STI Limited model. in a limited run of 800. which adds perforated leather seating. heated seats. a moonroof. and a "stealthy" appearance package.
