Looks great so far. I'm really excited about this car. I know a big emphasis for this car was on the interior supposedly. I can't wait to see it in person.
At least it's good to know they were testing this car with a 350Z. I always wanted a Vette, but it's a little too $$ for me, so the Z was my second choice

Hmm...
I don't like it much... Looks like a morphed C5 :-(
I'm missing the excitement of a smoothed out C5.... ugh...
Where did the 4-5 years of development go?
Look way too much like the C5, which I'm not too hot on either.
Now *this* is sexy...

There have been some rumors swirling around the GM may stuff a V12 into a future version the C6 and try to compete w/ the Ferrari GT cars. I'll see if I can find a link to some info for you all....highly unlikely? Yep, but fun to chat about none the less.

C6 Z06 would have received a new 6.0 liter V8? NOT!
It's even better than that according to MotorTrend.
It will be a 6.3! liter V8. Even more interestingly, it will incorporate a 3 valve per cylinder design. And still OHV/pushrod design of course.
The more amazing part in the story is that it will turn safely all the way to 7000 rpm and although out-of-the-box, fuel cutoff will be soon after that, this engine is certified for 8000 rpm runs with no problem! The engine will make 500 HP at 7K and this figure might be revised by next year (I am guessing upwards).
What's amazing here folks is that GM managed to have their cake and eat it too. Here is why:
In general, we have 2 schools of thought when it comes to engine design. The ones that make good power by reving higher and keeping displacement low (usually DOHC designs) and the ones that keep revs lower and displacement high to also make good power. And we all know about the torue curve differences.
To make a 6.3 liter engine that uses pushrods to rev to 7K rpm reliably, I believe, is impressive. Because I am guessing the advantages of the OHV design will be maintained with this engine. Things like low end grunt, low gas consumption and very high reliability. Oh and dont forget the most important of all. LOW COST.
We know we got the Displacement On Demand functionality incorporated with this 4th Generation small-black GM engine.
So what was missing was high revs. And now we got that too. Comparing the Italian school (hint: Ferrari), where high revs is the name of the game for high HP results (although displacement has been reaching USAmerican levels lately), I believe, GM wins.
Why? Because, the OHV design is so much cheaper, moderately more reliable, uses a lot less gas and makes so much more low end and mid range torque, you cant but call it a winner.
Final note: 6.3 liters from 8 cylinders = 787.5 cc per cylinder. Max power at 7000 rpm.
Comparing that to the 3.6 liters from the Modena = 450 cc per cylinder. Max power at 8500 rpm
Murcielago's V12 at 6.2 liters = 516cc (although comparing a V12 is not a fair comparison - works totally differently - though inertia is inertia). Max power at 7500 rpm.
Many more examples...
Bottom line, it's harder to make large parts move at high speeds and it's even harder to make an OHV design operate at high speeds.

that and the engine overall. Based on what you wrote it looks like a high reving ohv engine for consumer production is new territory. Sometimes that new stuff isn't reliable in the long run. But I love the Vette and hope it's bullet proof.

One HUGE additional advantage of OHV over DOHC engines is packaging. They're typically smaller and lighter than their DOHC equivalents; in the case of size, they're usually smaller by a LOT.

True. Specifically on height. A lot smaller in that respect due to the fact that all the intricate and numerous parts of a DOHC design make it a tall engine requiring higher center of gravity levels (a big problem for sports cars) and higher hood designs (an annoyance for designers).

hmmmm nice but is this really all that impressive? Old school muscle cars had similar setups with massive displacement and gobs of trq? Tech has evolved quite abit. It's cheap, should make for a fun car.....

i wonder if i can throw this in my cl?

I just read the article in MT, and I gotta admit I am impressed. GM sure knows how to made a small block pushrod V8. Lets hope that the price tag doesnt reach too far above what the C5 costs. Thats the coolest thing about the Vette is that it is the poor man's supercar.

IMO...
regardless of whatever engine the stick in there. The pics looked like a face lifted C5... And it took a long time for the C5 to *grow* on me. I like the curves of the old stingrays. I really wish GM would get off the edgy look. And back to sleek.

But dont forget that the base cars will also benefit. I would not be surprised if a 380HP V8 CTSxxx would be available for less than what the current 400 HP CTSV costs today.

True and I am sure GM wont make the mistake to take that aways from the Vette. Every automaker should have learned that lesson by now (we saw it happe in the 90s by cars like the Supra, RX7 and others).

moreover, this car isn't going to be good for the environment OR get good gas mileage heh
