ME>three engineering issue being sorted out....?

First, all GM products are shifting to a new electrical architecture—the means by which 100 or more computer modules per vehicle communicate on what’s called a CAN (computer area network) bus. Engineers are having difficulty working the bugs out of the new Global B party line serving Corvette and several other new models.
The second issue is a structural distortion of the aluminum spaceframe experienced during testing a prototype equipped with the 900-1000 horsepower twin-turbo V-8. The twist in back was enough to fracture the glass hatch covering the engine.
Item three is some unspecified bone of contention between those who design Corvettes and the development engineers who steer them to the far corners of the performance envelope. It could be a visibility issue, some ergonomic shortcoming, or a cockpit design problem.

GM Global B eh? First I've heard of that.
I think that Corvette would be the first of any new electronic architecture? Everything right now I'm pretty sure is still GM Global A architecture. I think even the new Silverado is Global A. I could be wrong however.
Anyone know what Global B is on if anything? I would hope that if they were smart, they'd have launched it on a high volume car to figure out the bugs and not a low volume high dollar sports car.

Sounds like Corvette might be the first. Article on Global B from 2015: https://www.reuters.com/article/us-a...0P42UY20150624
Interestingly enough, the new Chevrolet Infotainment 3 has a taste of this as the new radios have over the air updates. Global B however sounds like its over the air compatibility for ALL modules within the vehicle, not just the radio. Think like Tesla.

I find it hard to believe that design can't improve on visibility around the car without cameras, instead of making it progressively worse.

I would think that they would try it out on a low volume car that gets use as a 2nd or 3rd vehicle. If they have to recall all trucks it would be expensive. A few corvettes, no big deal.

On hybrid models, electrically driven front wheels will consume the (front) trunk space otherwise used to carry two sets of golf clubs in the base model.

If accurate... those things will take some time to work out and re-test. Not necessarily a good thing relative to how long we wait for the car.

Global B sounds like their over-the-air update system: http://www.autoconnectedcar.com/2015...-mobile-cloud/
Due to the nature of the OTA update system, much in the base levels of the network protocol has to be revamped to secure it. It wouldn't shock me to find out that the C8 is one of the first to use a new network architecture, or that if it is, some delays can be attributed to it.
And even with GM never announcing a timeline or even admitting what the program is, some are still insist something that doesn't even have a public timeline can be publicly delayed.

I have no doubt that there is some delay on the internal manufacturing schedule. I doubt that any car has ever been produced without some type of internal delay. But we are talking about a car that has not been acknowledged let alone been given an announcement or production date. If issues are serious enough it may not ever see the light of day. So, until it is acknowledged and a reveal date is announced then it is not delayed. Right now the camo cars we have seen may only be an engineering exercise.

Of course they wouldn’t, but since the next gen Vette has not been acknowledged that is all we have. Or maybe what we are seeing is a new Buick sports car. But I will admit that what we are seeing will ultimately be the new Vette. We could be looking at a 2020 Vette, or maybe a ‘21 or a ‘22 or ?? We won’t know until it is acknowledged/announced.

Where do you suppose where the upper control arm is attached? What about all the different materials that are used in this chassis and what are the various methods of connecting them together?

Until GM has the C8 on their website with a big banner that says "Available Season YEAR" and we are past said season and year, to me there is no delay. Without a promised timeline, there can be no delay. Is there likely an internal delay? Heck yes, if it is anything like every program I've ever worked on, but that means nothing externally, because nothing has been promised.
