Info on the U.S. version of Subie’s rally rocket is still a little sketchy, but here’s what’s new.
October 2007

More details have finally emerged on the all-new version of Subaru’s top-spec version of its Impreza hatchback, the WRX STI. Based on the Impreza WRX five-door—yup, in case you hadn’t heard, the STI will be available only as a hatchback—the STI gets distinctly more aggressive body work, including pronounced fender flares, a deeper chin spoiler, and a larger parasol wing over the rear hatch.

Unfortunately, the Tokyo introduction was limited to the Japanese-market model, which has a 2.0-liter turbocharged four, so information on the U.S.-spec version is still cloudy. We do know that the U.S. car will continue to have the 2.5-liter boxer four, however, which makes it easier for Subaru to meet U.S. emissions standards.

The 2.0-liter in the Japanese domestic market model delivers increased output, now up to 295 horsepower and 299 pound-feet of torque (SAE), using 16.9 psi of max boost via an IHI turbo. Subaru was not prepared to discuss specifics of the 2.5-liter engine other than to say that power will be “under 310 horsepower” and torque output will be a smidge lower than the 2.0-liter’s, at about 295 pound-feet.
