The model will likely be based on the same long-wheel-base Theta platform underpinning the Chevy Equinox and GMC Terrain, and take design cues from the Buick Envision Concept. A production version of the Chevrolet Aveo RS Concept first seen at the 2010 Detroit Auto Show will also be unveiled and will take the name Sonic RS; while room will be made for two Chevrolet concepts taken from their North Hollywood design center. Photos displayed are of the Buick Envision concept.
