Still it was not clear through these photos, one version of the Impala seen in the design studio before styling was locked in -- a full-sized model made of clay -- featured some design cues similar to the previous generation Audi A6, sources said.
A large, tall, split grille similar in execution to the 2013 Malibu was positioned on the clay model. The difference for the 2014 Impala's grille was an abundance of chrome-like materials.
GM typically won't discuss new products at this stage of a redesign.
"I can tell you there will be a next gen Impala ," spokesman Mike Albano said in an e-mail today. "Not sure I can go much beyond that."
