Subaru STI Performance Concept previews a bright BRZ future

And while this marks the world's first official look at the STI concept, Subaru gave me a preview of the car, and a long description of its significance, on a trip to Japan last month.

The Performance Concept sends a tangible message about the motorsports heritage and engineering capability of Subaru Tecnica International. STI started life as the motorsports arm of Subaru parent Fuji Heavy Industries. Appropriately, the concept car uses a racing powerplant. Under the hood is the same turbocharged, 2.0-liter boxer-four that powers the BRZ GT300 from Japan's Super GT series, estimated at around 300 horsepower and 330 pound-feet of torque.

But the STI concept is more like the ultimate road version of the BRZ instead of a recapitulation of an existing racecar. Chassis, suspension and braking components can all be found on the Japanese Domestic Market's road-going BRZ tS, for instance. Subaru invited me to drive the tS on that same trip, so stay tuned for a report on that experience later this week.
