We do:

Sounds official to me!

 

Weight has not been officially announced, and they have hinted at equal grip from new tire tech. Consider the skinny-tired and overweight GTR. No AWD on the C7, of course, but computers and other tech may well surprise you.

And that's the problem with so many folk's logic. They don't even consider they could be wrong. After all, you are probably correct (if only by a very small amount in practical terms) but being so cocksure about it sets you up for embarassment.

 

I remember my C6 Z06, 4000 RPM was about where you really started to feel the power and its increase, so how meaningful is GM claim? Big deal you get SUPPOSEDLY the same up to 4k tq curve if power starts dropping off like it does with the LS3 instead of going up like with LS7? Are we talking diesel trucks here or sports cars.

My definition of performance on the street is very simple: 0-60, braking distance, handling and higher speed lane changing. I can see someone with LS2 C6 without Z51 on stock run flats switching to C7 and noticing difference. Are these people the 80-95% C7 owners? Then you may have a point. What about others though? With LS3 cars and upgraded tires and wheels and GS cars? They will all notice the difference? This one I would like to see and will test drive C7 to find out for myself. So yes, I actually do not know and tend to be skeptical toward GM claims.

 

Until they come out with a Hipo version of the C7, the base/Stingray will not outrun a C6Z in the straight's or at the track. Im sure it will perform very well but the Z cars are a beast!

 

Careful how far out on that limb you go. It is certainly possible that given the eLSD/Performance Traction, etc., etc., it is going to be a driver's race.

 

I'll go way out on the limb...not happening!

 

, but I think a lot of us former ZO6 owners will be waiting on the C7 ZO6, which should be a great vehicle if it comes with the a 7.0 L Direct injection engine and optional dual clutch trans, for me that would be an evolution forward

 

Yeah... I'll be happy to climb out on that limb too...

Anyone expecting the new base C7 to compete head-to-head with the C6 Z06 (not even gonna mention ZR1) from a performance perspective is fooling themselves. GM has already clearly stated several times that the HP is down and weight up (from C6 Z06). The only hope for the base C7 is a 'quickness' created through gearing; however, even there I believe the base C7 will be lacking (again, compared to C6 Z06/ZR1). Physics is Physics... and all the high tech do-dats you add to the car can only help so much - usually provided as a safety net for most and only shaving 1/10's to secs off experienced drivers.

GM could have done the same thing they did going from C5 Z06 to base C6 (upping the new gen's base performance to previous Z06 levels); however, in this case they've indicated a choice to do otherwise no matter how much some wish they'd followed the same model as before...

 

In normal driving I'm never over 30% throttle either, but that changes in hurry when I mash the pedal. With the C7, in first gear, you are below 4,000 RPM up to 31 MPH. If you keep it at WOT to 90 MPH, you will be over 4,000 RPM the full time.



So, the C7 will be even with my Z06 up to 31 MPH and then it's bye-bye to you from then on, because if you run it to red line(6500 RPM) before shifting, you will never drop below 4500 RPM, and the LS7 rules from 4500 to 7000 RPM. With the C7 Z51 you will have to shift into second gear at 51 MPH. I'll still be in first gear until I have to shift into second gear at 61 MPH. Then you will have to shift into third gear at 72 MPH while I'll still be in second gear when I hit 90 MPH.

But, you will get better gas mileage then me. LOL, as I only get 28-29 MPG cruising on the Interstate at 70 MPH with my 505 HP.

 

Until it drops a valve and hand grenades the engine

 

0-31 MPH won't be the only time. When you are cruising next to a new C7, and for some reason you both decide to downshift and mash the loud pedal at the same time, odds are you won't hit exactly that powerband you so love. At whatever speed you are doing, if you both hit, say, 4K RPM on the downshift, the C7 basically stays with you for at least 1500 RPM -- and maybe he gets you at first if the C7 nannies work better than the C6 nannies. Then when you inch by him, as he downshifts to get back into the powerband, I'm sure he'll sit back in his much superior seats and have a chuckle. If he has the A6 and it downshifts as quickly as I believe it will, he'll get you 9 times out of 10, though if there's enough room, you decide to act irresponsibly, and there are no LEO's about, you will eventually pass him.

Look, we all get the physics of torque, HP, grip, etc. What too many C6 owners in this section refuse to admit is that it takes a better driver than most of them to really extract the differerences. I've not driven a C6Z, but as an example, in a straight line my C5Z and I would probably lose to the heavier and less-aggressively geared 2005 C6 with the A4 nine times out of ten just based on driver skills needed to optimize C5Z performance. I know that when I drove (what really is a pretty heavy) A6 GS it was way easier for me to blast off than with the Z. Of course there the HP difference is pretty material.

 

You really should drive C6 Z06 before discussing this subject, can be a big eye opener and it will give you a better frame of reference. You actually do not have to be a great driver to extract loads of performance from last Z06, this is what sets it apart from many other cars.

 

Good thing LT1 will have plenty of carbon build up to hold the valves and the rest of AFM hardware in place...

 

Funny, the 6.2s out there with the multiple cylinder displacement don't seem to be suffering carbon issues that I can see.

And what kind of cheap crap fuel are you running to worry about carbon build up in the first place?

And why are you driving like such a grandma that it can happen either for that matter?

 

We have a Tahoe in the family (my sister) with 110k miles and no problems in that regard. OTOH, it doesn't have DI..... so the fuel still hits the valves.....

 

We do have numbers. You guys just don't accept them and are wishing for a sudden miracle.

 

There is 6.2 out there with both DI and AFM on a production car? Got a link?

 

6.2 Camaro has AFM, 5.3 Tahoes do, as did the Monte Carlo SS.

And DI has been on the 3.5 V6 for quite some time now (since it's launch).

Neither component has proven to have major issues.
And if anything, the DI combined with this will have -less- carbon issues.


If you were the least bit literate you'd have noticed I specifically said the 6.2 with Multiple Cylinder Displacement.
You might want to get that strap on out of your backside

 

Are we discussing cars or drivers? When comparing one car against another, you have take the driver out of the equation or you won't get a fair comparison.

I really find it amusing when people say a good driver in a bad car will be faster then a bad driver in a good car. Well, a good driver in a good car will beat a bad driver in a bad car. So, for a true comparison of two cars you have to have either two bad drivers or two good drivers, not one of each.

So, for fun, lets say you, in your C7 Z51, and I, in my C6 Z06 are cruising side by side at 60 MPH in 6th gear(me) or 7th gear(you) and we both downshift into what we each believe is the most appropriate gear for our individual cars.

Now I will down shift into 2nd gear as that will put me at 4600 RPM, and I will then accelerate to 90 mph(7000 RPM) in 2nd gear. Even if I shifted into 3rd gear, my RPM would still be at 3400, and at 3400 RPM I still have as much torque as your LT1 at 3400 RPM and I would be at 125 MPH before I would need to shift into 4th gear.

What gear and at what RPM will you down shift into at 60 MPH?

 

I asked specifically for both on the same motor but thanks for more oranges anyway.
