Subaru has unveiled the STI Performance Concept car at the 2015 New York Auto Show. The concept car boasts a compact 2-door build, a wider and more aggressive body than the Subaru BRZ, while a large rear wing and flared wheel arches accentuate the sporty aesthetic. The latest silhouette showcases much of the same features as the Subaru BRZ, including the aero upgrades, chassis and suspension components, as the turbocharged 2.0-liter boxer-four engine produces around 300 horsepower and 330 pound-feet of torque. Subaru has yet to disclose official numbers, but a good number of improvements to the existing engine, suspension, and chassis are expected to equip the new STI Performance car.
