Impreza WRX STI Sedan shown in WR Blue Pearl. More than three decades since Subaru adapted all-wheel drive (AWD) into the lineup, we continue to set the standard with our trademark Symmetrical AWD. With its balanced layout, power fl ows directly from the engine to all four wheels for more immediate acceleration and effi cient response to any slippage. Should the road surface suddenly change, the AWD system instantly redirects power from the wheels that slip and delivers it to those with greater grip. AWD also helps you maintain better overall control of your Impreza with greater composure turning in to and accelerating away from the apex. More stability. Enhanced safety. Maximum adhesion. A pure rush. The thrill of driving is not defi ned by mere horsepower. Its in piloting a car that feels like a telepathic expression of the drivers will. One that exhibits quick reflexes and unfazed predictability through S-curves, hairpins, switchbacks. Thats why every chassis component of the Impreza, with its precise rack-and-pinion steering, rally-inspired rigid and lightweight body structure, 4-wheel disc brakes and independent suspension, is engineered to perform like its hard-wired to your cortex. Handling Chassis Symmetrical All-Wheel Drive Continuous AWD In models with the 5-speed manual transmission, power is normally split 50/50 between the front and rear wheels. Should wheel slippage occur, the viscous-center locking differential automatically helps transfer power away from the wheels experiencing slip to the wheels with the most traction. Active AWD Paired with the available 4-speed automatic transmission, the Active AWD system features an electronically managed continuously variable multiplate transfer clutch. This system monitors parameters such as wheel slippage and vehicle speed, actively seeking to adjust power to the front or rear wheels with the most traction. VTD AWD The Variable Torque Distribution (VTD) system of the WRX Limited with the 4-speed auto- matic transmission normally splits power 45% front and 55% rear to deliver a sporty feel. With a planetary-type center differential, VTD electronically apportions torque for maximum grip. It also features a viscous-type limited-slip rear differential. Suspension Years of insight gained from intense World Rally Championships coupled with the rigors of real-world driving went into the development of the sport-tuned 4-wheel independent suspension. The result is responsiveness and communicative nature of a precision-tuned vehicle. Impeccable road manners, with more than enough verve to take on the curves. Body strength The Impreza is built on an extremely rigid platform, which not only aids its considerable handling abilities, but also provides a solid, smooth, quiet ride.
