A V6 is not something dreams are made of. A V8 would be considered the minimum.

Maybe to shorten the stroke and increase the rev? Historical precedent but I don't believe it will happen for the base.

He also said GM plans to keep C7 fresher than C6 by doing more consecutive updates to the car over its life cycle.[/QUOTE]

That would be good. The C5 and C6 were the only 2 generations of Corvette that had 0 updates on the body.

Sure, but if the choice was to have a Corvette line or not to have one... then as desperate measure I can see them throwing in the V6 for the base. They could lower the price to $49k to market it as a cheap affordable economical 'vette. Maybe throw in that it's lighter and more nimble. Sure some Americans would skip it, but many more around the globe may buy it more readily. Let's not forget there are many buyers who just want to drive around in a new Corvette regardless of the performance. It won't say V6 on the back bumper and that may be good enough.

Turbos could come in to make the argument that performance was improved while efficiency went up as well meeting the new blah blah blah spec that CAFE introduced.

One could say base cars are never dream cars anyway. Or that 6 cylinders could make for a dream car. Look at the 911.

Anyone with ears will know its just a V6. Anyone inside the car will know from the vibration.

This sounds like a great way to water down the image that the Corvette team is so deparately trying to rebuild.

If someone could drop by planet Earth for a moment, I have a question.

For real world, public roads driving, what is an 8 speed auto going to give you, that the 6 speed doesn't? Thanks in advance.

I don't know, i don't have to be the first kid on the block to have one thats for sure but after reading this thread there seems to be too much uncertainty in the direction the car car is going. it seems it will be heavier than the c6, im almost certain my '12 coupe would give it a run for its money if not beat it in a strait line of course. its a nice car and i know there is no performance data at all on the car yet but come April when the new kenwoods come out with the idata link the c7 technology will be old by those standards when i put that system in my '12 coupe. I'll play the C7 scenario by ear.

Would a 60 degree V6, or a 90degree V6 with a balancer vibrate more than an unbalanced 90 degree V4?

Will AFM ruin the C7?

GM will flex it's competitive advantage, and that is a large OHV vee formation engine. It doesn't have to be a V8. BMW's advantage was valvetronic and it couldn't rev past 7k, so the revs where lowered despite enthusiasts crying out.

You already made your deposit so you did want to be the first at one point, evidently. But hey, it's your deposit...

This thread is totally meaningless as to where the Corvette is going. So are all the other threads until you hear it from GM...or see a leak!

Definitely worth to wait a bit until some users put mileage on theirs and report back. I would also want to see how loud the DI pump is.

For those on CF who own them, they are uniformly positive in their comments.

It is a FACT, not my opinion, that GM failed miserably with AFM in the GMT900 trucks.

There is a TSB for lifter issues. Supposedly they were working on a redesign of them in 2008, but were replacing them with the same faulty ones. There is also a TSB for excessive oil consumption which was a band-aid, not a fix. They install an oil deflector shield to try to prevent it from entering the combustion chamber. Most saw very little, if any, improvement.

I have my AFM turned off via my tune. Over and above the issues it has, it was 100% completely worthless.

Oh, and just an FYI, I have well over 30,000 posts on a few different GM turck forums since 2007, so I think I know a bit about the issues and consensus of AFM in the GMT900 trucks as compared to the tiny sample of them here on a Corvette forum.

Hey, my '82 Silverado has a 350 so what do I care? Just reporting what I have read right here at CF regarding modern GM cylinder deactivation systems.

Default This is spot on IMHO

Couldn't agree more with BlueOx. The Corvette brand needs to be expanded with some smaller Porsche Cayman style cars along the lines of the Pontiac Solstice, just not with crappy old fashioned rough motors. GM have some fabulous 4-pot turbos (Buick Regal?) which will bring their EPA (CAFE) ratings up. Keep the Vette with V8s and expand the range down with smaller models. BUT PLEASE KEEP THE QUALITY UP!
