Subaru reveals more about BRZ Concept STI

Curiously, the Concept STI does without a turbocharged engine – something that's become a Subarutradition with its performance cars. Instead, the direct-injected 2.0-liter Boxer four has been left unchanged. Never fear, though – STI has added a full smattering of performance bits to the BRZ, including a more aggressively tuned suspension setup, Brembo brakes, and lightweight materials (a carbon fiber roof and wheels, specifically) to reduce overall weight.
