All New and Used WRX-STI Model Years and History
Utilizing the already slick and solid backbone of the Impreza WRX, the WRX STI represents the zenith potential of Subaru's sport compact. STI (Subaru Tecnica International) first appeared as a limited edition, high-performance Impreza WRX in the Japanese market for 1994. The first North American version of the Subaru WRX STI would arrive for the 2004 model year as a contender against the Mitsubishi Lancer Evolution. Only available in a sedan body style, the 2004 Subaru WRX STI employed a 300-horsepower turbocharged 2.5-liter engine. A tall rear spoiler, enlarged hood scoop and special interior touches also defined the WRX STI. Returning with third generation Subaru Impreza's introduction for 2008, an updated WRX STI became a 305-horsepower, five-door hatchback. An aluminum hood, Brembo brakes and 18-inch wheels were also special equipment for the 2008 sport compact. A sedan version of the Subaru WRX STI was reinstated for 2011. Maintaining its 305-horsepower turbocharged Boxer engine, the 2015 model year brought a completely redesigned WRX STI marked with a specially-equipped 1,000-unit Launch Edition. Active Torque Vectoring was an added handling feature for the all-wheel drive performance sedan.
