What sources was the Autoblog report based on? Are they real or just the usual "obscure unknown insiders state" kind of stuff?
(I can't read the post itself, that site has too much scripting crap going on)
Autoblog knows no more than any of us. The whole article is speculation and guessing.
Not only this, don't forget they are also dependent upon suppliers and things who may also mess up or make changes. It's not impossible for Delphi to come back and say "hey, when we tested all the cool new features you put into the Corvette, we realized it ran to slowly, so we upped the components and need more power". And then GM redoes calculations, realizes that it is getting close to max, but should still work. And then during testing they realize, everything works great even with the new loads, except if you use both power windows at the same time, while sitting at a stop light when auto-stop has kicked in -- and they forgot to re-plan for that.
Exactly. This isn't just turn signals and wipers... the electrical buss is the brain of these cars... switches, actuators, computer modules... plus you have to make sure they will work for years with no failures... none of this is legacy technology... take the time, get it right. Its not easy.
Still find it almost impossible to believe that in this day and age of super computer simulations and Proto type testing and years of real world Field testing and data gathered from competitors cars that such a delay is possible. Somebody made some fundamental error‘s in assumptions and requirements early on and it was never discovered until a few months before they are about to go into production?
As a engineer formally employed on a car/minivan line....this is what we call 'project creep'. Different departments and stakeholders keep adding requirements (including marketing) until the camels back is broken by a straw. "
the engineers can make it so" and so 'they' throw hand-grenades over the wall, 'knowing' that the engineers will catch them and put the pins back in....until we can't!
Minivan day of pre-production unveiling (not pilot production yet) Chief Engineer; " We are 256 lbs over the weight target! Either we have to uprate the entire suspension and re crash-test the vehicle or EVERY department has to put on my desk by end of week every weight reduction they can achieve"....you can imagine the chinese fire drill.
I feel for those guys! X-mas in front of a Flat panel display!
Maybe they are kicking the ball down the road to buy time. With the major overhaul of GM and the new focus on a narrower group of vehicles, we must expect that GM reviewed every vehicle's strategy, so, the current corvette strategy has been reviewed. Who knows what the outcome of that review was? Leak an electrical issue and you have cover until you are able to unveil the truth. We'll know in 6 months, or we won't.... Either way, it's all speculation.
Possible June 2019 press releases form GM:
"Mid-Engine Corvette program shut down due to electrical issue"
OR
"Mid-Engine Corvette debuts to Global praise" (I'd prefer this one)
"The electrical system can't handle the required loads, so engineers need to redesign all the wiring."
Has Lucas, the Prince of Darkness arisen into the glare of LED headlights?
LoL -
To me it's kind of head scratching. It's a pretty straight forward problem. The only differences I can tell are the headlights and PS rack being further away from the power source. I know it's DC but you shouldn't be seeing that much of a power drop with the distances involved.
Is there anyone here who thinks this was the first problem found in the development of this car? That's why they call it "development" instead of "final product". So the ME becomes a 2021 instead of 2020, so what. Better to find the problems now and fix them than rush ahead and release a headache. Corvette owners are picky and very critical of minor issues.
I not surprised at this delay. Also, I don't think it will be the last.
Could be that they are struggling with the two tier voltage system. The Europeans have been at it since the late 90s. Volvo will be the first in production. Just saying.
Volvo will not be the first to use a 2 tier voltage system. They are not new. I cannot tell you who was first but ALL diesels that run HUEI injection systems run a high voltage section of the electrical system. Ford started using a 24 volt system on the 7.3 diesel in 1996 (Designed by Ford and used by IH, Ford and Cat) and has continued the system since. 2003 they went up to 48 volts. Not sure what voltage the current models use but I think its 80 volts.
Yes, they are going further and powering more systems with the 48volt side but its a matter of degree, its not new.
... And many still believe we went to the moon and back, successfully ... multiple times, ... *some 50 years ago*, on a mere fraction of the technology we have today!

Those minds are long gone from this good earth but were obviously superior proven by the results accomplished with the known technologies of their time.
Seems to me GM was trying to cut the budget and use existing parts which didn't do the job.
Let's hope its the only place they did this.
Amen to that.

Launching 3 guys in a can on top of a missile is not rocket science...
Or a family member of those who didn’t make it up on the first one. Proof that mistakes are made and it’s good to do things right and not be in a hurry to release something before it’s ready.

True.
It doesn't need to be perfect but at least safe and functional.A recall to fix a minor issue isn't bad but a harness replacement isn't a minor recall.

Look on the bright side.... by the time these really go on sale, I may have my 2016 paid off, and might actually be able to buy one of these buggers!
