While it still looks like a Sube, it performs like a racecar. The WRX STI (which stands for Subaru Tecnica International) gets its motorsports technology directly from Subaru expertise in FIA World Rally Championship (WRC) competition. Lots of changes for ’06: new 2.5L 300hp engine, new driver controlled differentials and re-worked suspension. Let me be perfectly clear: this car for serious driving enthusiasts only. Still looks like a Sube, though. MSRP: $33,600; Warranty: 3/36,000.
Generally, though, the WRX STI leaves no doubt as to its performance car nature. The big air scoop on the aluminum hood feeds outside air to an intercooler sitting square on top of the engine. The two-plane rear spoiler – very similar to the wing on the WRC car – helps to reduce lift and improve high-speed stability. Front and side aerodynamic underbody covers and side ground effects are additions to contribute to high-speed track stability.
