The top one is based on the Delta (Cruze) platform. To be an affordable, quirky offering for the 20 somethings. The bottom one is based on the Zeta (Camaro, G8, etc) platform, potentially a Chevelle for when the Camaro drops down in size to the Alpha (ATS) platform. I think both have potential and am sure they'll be toned down some for production (if they make it that far).
