However, while most of the interesting WRX STI variants have been offered to Europe and Japan only, whatever is wearing that carbon-fiber-lipped wing is set to debut at the New York Auto Show this week.
We don't have a clue as to the precise nature of the car in front of that wing, save to say that it's likely based on the STI. We can guess, however that the extra vertical supports and the use of carbon fiber indicate a higher-performance version than currently exists. Anything from a racing application to some new goodies for the aftermarket are in the realm of possibility.
Expect to see Subaru's surprise unveiled at the NYC show on Wednesday. Till then, have fun guessing at what car may be attached to that mighty tail, below.
