While Block's STI TRAX is an entertaining diversion for a clothing mogul/extreme sports personality/rampant gearhead, the Subaru Legacy GTk is far-and-away our favorite concept at the Subie booth.
Based on the 2010 Legacy 2.5GT Wagon, the GTk has been designed to strike a balance between family shlepper and SCCA Solo autocross competitor, beginning with a tuned and tweaked turbocharged 2.5-liter boxer putting out 300 hp and 350 lb.-ft. of torque. A six-speed manual transmission with a short shifter sends power to Subaru's symmetrical all-wheel drive system, while track-tuned Bilstein struts and STI "pink" springs suspend six-piston (front) and four piston (rear) Brembo calipers squeezing cross-drilled discs at all four corners. If all that and a set of custom HRE 19-inch wheels isn't enough, Subaru's partner in the project -- Specialized Vehicles, Inc. -- sourced a Formula Junior A class-spec kart that can fit into the cargo area -- no trailer required. We think we've found our next project, but the 1969 360 SPT Delivery Van needs to find a home in our garage. Full details about Subaru's three other concepts here and make the jump for the release on the GTk.
