A while ago we started to see a horizontal “shelf” on the C8 IVERs rear diffuser. It was first thought that its purpose was to keep the camo off the tailpipes, that maybe some of the camo had sagged, then started to smoulder or worse. But the diffuser has kept its shelf, and due to pictures by David McDade yesterday and today, and today’s article by Motor1 (with thanks to both for their approvals to use their materials), are we seeing the final design of the C8’s diffuser?

Second and important to all of us owners who are tired of the amount of filth that washes upward from the road surface and coats the rear fascia (and has especially done so since the C5’s flat rear), might the diffuser’s horizontal shelf component in addition to have a positive aero enhancement, reduce the amount of that dirt/yuk?
Lastly, and maybe I am slow to noticing this, how about that second, very-unearth secondary shelf? Aero squared?
