Here is an interesting unofficial rendering of the C7 Corvette by designer Andrei Avarvarii that takes some of the best features of the Transformer's Stingray Concept and morphs them with the best features of the C6. From the Stingray concept, we see the reworked grill area, sloping hood and high fender lines. We can't tell if this rendering has a spilt rear window, but since GM's Global Design Chief Ed Welburn says is coming, we'll patiently wait for 2012 when the real C7 is expected to arrive.
