The actual name of this concept car is 'Subaru BRZ concept STi', not just Subaru BRZ. It will be a RWD (Rear Wheel Drive), not an AWD.
Sitting on 18 inch STi signature wheels looked great on this concept.
An addition of a spoiler is something different from the Scion version. You can also see some differences in the overall rear section.
The estimated price will be around $25,000. As for the specs, I'll keep it as simple as possible. It will be a front-engine, RWD, and 6-speed manual, pulling around 200HP from a 2.0L Boxer engine.
