Zero chance it paces 24 Hours of Le Mans. Audi isn't going to just let them come take that.
Long history of new Corvettes at Indy... and it's not long after what... NY auto show? Definitely possible.
I wouldn't worry about being mechanically ready. The demands on a pace car are not extreme, the damned cars have been running the Ring and have been seen around town in multiple locations, that's more than enough to pace the 500. They could damned near stick a law mower engine in there and do it.
Pace cars are always production cars, and they are frequently recently introduced production cars. I don't recall any "coming soon" concept or developmental cars serving in that function. I don't think there's any chance the ME will be in production by Memorial Day because we would have already seen it.
If it paces Indy 500 this year or next, Jay Leno is one guy that loves Corvettes...He could be a good choice to drive...He has training and experience...driving 204 with Tadge in a ZR1 and...he brought it back in one piece...

The GM guy that crashed the C7 ZR1 has extensive racing experience, far more capable driver than Jay, he just got caught out in the same place many Indy car drivers lose it - on cold tires.
Yes, Mark Reuss (current GM President) is SCCA, IMSA, and FIA-certified as a test and race driver. Jay Leno is a complete amateur by comparison. It was absolutely a situation where he was trying to get ahead of race traffic on cold tires.
Antonio Garcia did exactly the same thing in the #3 C7R at the last IMSA GTLM race of last season. He was also coming out of the pits on cold tires. Fortunately, they managed to repair the car quickly and were able to hang on to the Driver championship.
As an interesting aside, the ZR1 has 250+ more HP than the GTLM C7R, and much easier to lose control of.
Take a look at that neg camber on the left wheel during the spin and the tire mark. C8 seems to have the same geometry. Beats me why Vettes since the C5 have this geometry. So much grip is lost. Why?
On a car set up for road course work, negative camber is a must so when the car is leaning into a high G turn, the outboard loaded tires have a full contact patch. You'd see a full contact patch on the other side if the mule above was entering a high-G right hand turn.
With neutral camber or positive camber, you lose the full contact patch in a high-G turn on the outboard side where grip is the most important.

So I understand what you're getting at. Even the correct alignment on my 84 has some on the rear. But if you don't mind my asking would it be more beneficial to have it neutral under normal driving conditions and then use the inherent loading of the suspension when going into turns to alter it negative? I mean the gar will roll some amount no matter what but is it possible to have the natural arc of the suspension travel change the wheel position to maintain contact rather than having it out while just sitting normal? Or is that worked into the geometry of the travel as well as the static negative camber?
Suspension isn't anywhere near what I study. Thermo and areo are more along the lines of what I know... but I can do basic force balances to understand why things behave the way they do. Like I understand but don't understand why.
Under normal street driving conditions, a lot of folks align closer to neutral camber, but the only way to maintain a flat contact patch on the outboard tires during a high-G turn is to use varying degrees of negative camber. Look at any road race car sitting on the paddock, and you'll see extreme negative camber on all 4 corners.
The idea is you want the outboard tires to have completely neutral camber while in a high G turn, and because of tire flex, the only way to get that is a static negative camber setup

Thanks. Now that extreme I imagine is significantly less than that ricer hella stance yo riding on the side walls... right?

Any chance the C8 will be the pace car at Indy 500?
