That's why that was a concept and this is the production model.The shape of that car is waaaaay different than the concepts.
One thing I liked about the concept was the low slung and wide look of it. Yes everyone knows you have to make changes from concept to production but the 5th gen Camaro has got to be one of the closest to concept executions I have seen GM do on a niche vehicle.That's why that was a concept and this is the production model.
Even the Camaro Dimensions changed from the Concept. It's probably not noticeable, but it changed significantly.
Plus, the Concept Volt wasn't as aerodynamic as it could be...
