NEW YORK, New York – Subaru today introduced a new 4-door version of the Impreza WRX STI performance flagship. This will be the first time that the WRX STI has been offered both the 5-door and 4-door body styles in the same model year. In addition to the new styling, the 2011 WRX STI features significantly revised suspension tuning and lighter 18-inch wheels for even sharper handling.
