These are straight up CAD images from the mid-engine car. This is your C8, people.
Somebody is gonna get so fired over this. Give it 2 hours, this will be all over Jalopnik, Autoblog, and others.
From the images:
-Coil springs (FINALLY).
-Magshocks (or spool valve, either way, fancy shocks).
-Upper front arms look to be similar to C5/6/7 with trunions.
-Lower front arms look to be similar to C5/6/7 with camber eccentrics.
-Rear subframe is HUGE and is a very strange mix of cast parts and welded tube. Can't tell if it's welded or bolted together in the middle.
-Engine is an LT1.
-Looks like factory shorty headers instead of cast manifolds.
-Engine has alternator relocated.
-Not sure what the upper-right accessory pulley is for. Upper left is water pump, lower right is AC.
-Oil filter looks easy to get to.
-Oil cooler clearly shown above filter.
-Half-shafts look to be the "bolt on flange" style (no draining trans to remove shafts).
-That transaxle is BEEFY. Like, dear god. Can't tell if it's auto or manual. If I had to wager, that's the automatic (guessing from shape of bottom of trans and what looks to be coolers hanging around it).
-Giant flat space above transaxle is more than likely for intake box/filter.
-No turbos shown.
-Frame looks to be similar to C5/6/7 with giant hydroformed rails (probably still aluminum). Disappointing. I was hoping for proper unibody. Hopefully with a fixed roof it'll be stiffer.
-Brake rotors are 1 piece. Calipers are MASSIVE.
-Side skirts are mechanically fastened just like C5/6/7. Still going to be horrendously expensive to fix if damaged.
-Brake ducts clearly shown on front.
Guarantee that Tadge is fighting some fires right now.
I'm not an expert at reading CAD drawings. But can someone tell by looking at these if the transmission is at the rear? If it is, does this confirm that manual transmission will not be offered?
The transaxle definitely appears to be at the rear of the car to me. You can see the outputs of the gearbox on each side, facing left and right, directly behind the engine. (the golden circles underneath the pink catalytic converters). This is typical for mid-engine layouts.
You can still have a cable operated manual transmission in this configuration. It would be just like the porsche cayman/boxster, which I believe is cable operated.

Between Figure 18 and the engine in the patent drawing.
I'm surprised no one having mentioned the Tremec TR-7007 and 9007. Does anyone think if that DCT would be able to fit in there?
It says it's "modular design for RWD, AWD, and trans-axle platforms." I'm not sure if that means rear engine layout. I'm not sure it's possible to design a transmission that works in both configurations; the output location is different and mid-engine trans are necessarily much shorter so that there isn't a huge rear overhang. I think trans-axle means the current corvette configuration, of front engine -> torque tube -> trans and diff in the rear.
So I don't think GM will use the TR-7007.

No way, this was very intentional. I really don’t believe someone would risk their job for a silly photo. As far 2018 reveal, sorry to break your heart but I extremely doubt that will happen.... almost certain. We are looking at a 2019 NAIAS reveal. These photos are interesting, hopefully a ramped up LT1 making 500hp. I was really hoping for a DOHC for the base model but I guess they will use those for the forced inductions models.
I bet it won't make more than 475hp. The only revisions GM will make are intake/he/exhaust and tune. There is more room for proper headers, as the CAD shows which will net 10HP. I doubt GM will throw any money at the small block anymore when it has to develop a DOHC turbo.

I disagree. If the MR is to eventually replace the FR then it would be smart to have the pushrod for lower tier models to hopefully keep the price closer to where it is now.

I never said the small block won't be used, quite the opposite.

I hope it's at the rear otherwise it's rear engine

Like my father tells me (especially when he is trying to fix something around the house) “have ye faith”. I believe with the short headers, better tune, and better air induction system, I can see them easily getting 500hp crank. As long as it is more then the ordiginal 465, I will be very happy.

Trans is at rear. If it was underneath it would be a front drive or a Testarossa.
There have been mid engine cars with manual trans since the 1930s so no issue there.

These look pretty legit, no way some rando cooked these up himself in CAD, way too detailed.
Possible GM could have released these on purpose

I figure at some point GM will turn up the heat on IB and you will be sent to the rack as punishment.

The one bigblock427 is using looks damn good to me.
I have other body suggestions also.
