Default Flaw in the renderings

In many of the renderings i'm seeing (C&D jalop, trinity, etc). They depict the back hatch supports running straight back, parallel to the side of the car. Not onlu is it wrong, it looks terrible. The roofline flows in a straight line from the A-pillars back to the deck-lid. When looking at it from the rear it would flow in a definate taper inwards as it flows down amd back.

The C&D pic shows these lines ending at the middle of each tail light. They actually merge with the deck at the inner edge of the tail lights that flow in a single plane. Which IMHO will look way better than what the current renderings show.

Here's the CAD. See how the rear sail panels conjoin w the rear deck inside the tail lights where the buldge in the deck is?



Now look at the A-pillars in this pic. Follow them from their base up and over the car to the back. The sail pannels / roofline edge follows them in a straight line that tapers inward to a single point towards the rear of the car (the point at which they converge would be beyond the length of the car, but you get the design cue)
Almost like the boat-tail taper to the C2. There's none of that visible in most of the renderings.



Here's the C&D rendering. It shows the sail panel. Turning outward (relatively as opposed to flowing in a congruent line from the A-pillar) from thr top of the A-piller to flow rearward parallel to each other and the quarters of the car, which is clearly in acurate.

Its a small, subtle difference, but one I feel changes the look of the rear of the car completely.

Yes, that has been a consistent issue. Keeks has said it does taper inward as it approaches the spoiler though, so I'm not worried about it. I was pretty floored when I first saw the renderings at how hideous that straight back was, but learning that it tear-drops put my mind at ease.

In the first pic I posted of the CAD drawing. Look at how the inner most point of the tail lights (bezel) comes to a point? I bet if you squat down behind the car and follow that angle of the inner most point of the tail lights upward, it lines up perfectly with the edge of the roofline.

There are a ton of these liniar design features on many of GM's new cars. I first noticed this on my budy's Camaro. Next time you see one, don't just casually glance at it. But walk around and look at it. Follow the lines with your eyes from different angles. Everuthing just flows and lines up beautifully. Way more intracacy than one would notice from a casual glance. I assure you the C7 will be no different

Your design summary is refreshingly accurate but you did not mention the glass in the hatch. Why all the crazy camo on the hatch glass RJ ? Do you see anything out of the qrdinary?

Thanks.

As far as the hatch goes. I think the CAD's that Keeks posted are it. The only problem them are is they make it it veru hard to determin depth and spacial relationships. So its just hard to really appreciate it. I believe, the sail pannels and the tear-drop shape will blend well together on the final project. Giving homage to both the mid year (C2) and the early C3's that also carried a Stingray name. Perhaps the sail panels on this design were the inspiration for reviving the stingray name... Or vica-versa.

The reason for alllll the camo? Its such a radical departure from recent generations and the bubble hatch, they try hiding it as best they can. Besides, it works. Obviously fooled C&D a little.

I agree with the OP's assessment and, as I have said all along, we will have lots of details like this that will show up when we finally see it for real.

The tail lights/rear end will live and die on details like this. The interior will reveal a ton of details that add to the whole package and I think folks are gonna love this car.

you are 100% correct. The tapered rear glass will give the car a completly different and better look. The quarter vents seem out of proportion too (too small) and the quater window angle looks a little off too.

When the Trinity renders came out, the ones with the C5, C6, and C7 comparison.. that was one thing I thought was way off. The rise-up in the rear facia is where the the sail panels/c-pillars will end. And it's clearly much narrower than the spot they start @the the b-pillar.. behind the door windows. So it has to have a pretty substantial taper that the C&D render misses badly. Some of the similarities between these and the Trinity ones makes me think they just used those as a starting point and added details that have been made clearer since those were done, and just overlooked the shape of the rear window. I also think they are showing the glass going too far toward the top.

Mike, didn't you do some photoshop work a lil while back? If so I was wondering if you'd be able to tweak this as well.

This spy shot gives us a better idea of where the roofline meets the rear end of the car. The roof lines will end at the black portion of the center brake light. The C&D rendering is not quite accurate.

More like this. That bodywork in the center at the base of the glass should be a little higher than outside of the sail panels too.

That is a big improvement. If you can change the tail lights to the u-shaped ones you got it.
