This is what was indicated online about the car shown.
Designer Larry Shinoda usually got the look right, but nothing could keep this idea from being more wrong. The notion was to build a "junior" Corvette on the rear-engine Corvair chassis, in the hopes that some of the Vette's good mojo would rub off on a less-expensive car. Considering the Corvair's ultimate fate, it's best that this plan never went beyond the clay-model stage.
Is the picture posted the clay mockup?
