Though Subaru engineers took careful measures to ensure their Impreza WRX STi tester wasn't spotted en route to the Nurburgring or at the track's staging area, eventually the car cover had to come off. It appears Subaru engineers were forced to unveil the production body of the new STi in order to test how the final form affects cooling. Though we just showed you this official teaser shot of the STi, these spy shots show the car outside in perfect light where every detail of the new design is cleary visible. Aside from some black tape, the blue STi underneath is practically naked. Note what appear to be air extractor vents or intake scoops on the sides of the front bumper, a design element we weren't entirely aware of before. We can also clearly see the rear wing now, which is less ostentatious than we were hoping. The STi has always been known for sporting an obnoxious rear wing, but it looks like that tradition will end with the 2008 model.
