Cooling and air intakes
I may have missed it somewhere, but why do all of the renders have huge intakes on the flanks. I assume that the radiators are in the nose based on the grills. So what are the intakes on the flanks for? Cooling for the brakes and maybe coolers for the differential but those can be done with small intakes like the C7 has. So why the huge side scoops?

For starters, there's this chunk of aluminum called an engine that needs a little air to breathe. After that you have brake cooling, transmission cooling, differential cooling, power steering cooling, engine cooling, the a/c condenser needs air flow, the engine compartment in general needs to be vented for heat and pressure.

The huge scoops on the flanks are really only needed on the forced induction versions. Doesn't take much to get air to the air breather on a N/A model with 500 HP. The engine coolant radiators get their air from the front of the car.
Look at the Porsche 911. Most of them do not have the large flank mounted scoop, until you get to the high horsepower turbo versions.

So, why not do the base model without the huge scoops but with smooth sleek quarters, then later when a turbo or whatever comes along do the scoops as a model to differentiate it from the base model?

Okay, just looking at some spy photos out today and it appears that the engine radiators are not in the front (no air outlet in the hood, so must have a front trunk). That would mean rear mounted radiators and thus the need for the huge scoops.

Look again at the spy shots of the mid engine Corvette's at the Ring. Notice behind the front fascia grill openings, that there are heat exchangers(AKA as engine coolant radiators). They are mounted at the extreme ends of the front fascia, thus having a center mounted hood vent wouldn't work very well. Also the CAD drawings of the space frame show a frunk in the center of the front of the car between the frame rails and just behind the front bumper beam. Difficult to have a sealed frunk for your luggage, etc, if there is air flowing through it from a hot center mounted engine coolant radiator.

I'm guessing that Porsche chose to have different body panels and internal ducting and was not worried about costs. but the bean counters at GM didn't want to spend the additional money in molds, etc to have different rear quarter panels and internal ducting for different models. Like the hood vents on the C7, possible that GM wanted the large side scoops to make a " styling statement" vs designing what is actually necessary to be 100% functional for each application, as Porsche apparently does..

The C1 through the C6 ZR1 had a front mounted radiator and did not have a hood mounted vent. GM needed the C7 to look different from the C6 so they included a hood vent.

I agree with the logic but we have two separate eyewitnesses claim that at least one version of the car has a hood with a center mounted far back vent that may be split in two.
The forward position and storage does complicate the designed a bit but I am sure ducting could be worked out to allow A center vent, or conversely, maybe they eliminate the front trunk on the Z06/ZR one versions?

The early cars with the padded camo had hood vents and an open center grill. The latest pics of the cars with only paint camouflage do not have a hood vent and most of the center grill is blocked off. I could see the center grill being blocked to hide the grill design. But how do you hide the hood vent.
