wow !!!!!
The vents on top of the rear fenders direct air into
the vehicle to feed cooling systems for the transmission
fluid and electronic limited slip differential, which then
exits through openings built into the brake light housings.

I keep hearing references to electric rear diff.... does that mean the rear brakes are being used to simulate a diff? My bmw 135i had an "e-diff" like that, but the rear end itself was an open differential.

No, actually is active and works as an open diff. going into a corner then applies power to which wheel needs it as you come out of a corner. Tied to computer if I understood correctly.

The rear vents are supposedly for cooling as some say.
But, they don't do very much when you look at the air flow analysis. Watch the videos and read interviews from some of the design team and they clearly say they were primarily added to make the C7 look more "rear mid-engine". They are there for visual design and to make it look different than the C6.

It's the new water collection system. Collects water in a small reservoir to dump on your tires after a burn out. Cools em down...

I get asked the same questions on this vent...
Originally, it was supposed to feed air to cool the rear brakes, but when it came time to actually build production cars for the consumer, it was nothing more then a styling gimmick. GM realized it wasn't needed to cool the rear brakes on a production Corvette and to make it functional just ran up the cost of the car.
It lasted as a fake scoop/vent for two years on the 1956 and 1957 Corvettes and then went into the stylist's waste paper basket.
I'm sure GM could design a method to cool the automatic transmission and the differential without having the big black vent on top of the fender, and do it without hurting the car's aero drag. The vent is probably 10% functional as a cooler and 90% functional as a "let's make it look like a rear engine car" styling gimmick.

Don't get made at me. Watch and read what the design team said.
