It also features Dual Active Valve Control, optimized combustion and a free-flowing quad-tipped exhaust for invigorating output, instant acceleration, inspiring response and an intoxicating sound across the entire rev range. SI-DRIVE (SUBARU INTELLIGENT DRIVE) With the SI-DRIVE engine management system, drivers of the WRX STI can choose among three different drive modes to match their mood: Intelligent Mode (I) delivers smoothness in low-traction conditions and boosts fuel economy by as much as 10%; it’s perfect for driving around town and in stop-and-go traffic. Sport Mode (S) is for all-around use; it provides linear throttle response for everyday driving situations and extra engine power when needed. Sport Sharp Mode (S#) exploits the full potential of the SUBARU BOXER engine; it delivers instant throttle response for maximum enjoyment. 12
