Guys

There has been several post regarding this question.

Several have said the C7 is faster on the drag strip, but to me the numbers don't indicate that.

There are some videos popping up but none I have seen against a Z06.

Some have said they are faster on the road course. I saw a post last week where someone from Spring Mountain said that in fact the C7 was just as fast as the Z06 on their track with their drivers

At the NCM HPDE at VIR this past June I talked with Art Spunge from GM who had been at the recent testing at VIR. He said the C7/Z51 was 1 1/2 to 2 seconds behind the standard Z06.

Given the updated electronic controls, almost identical torque curve, E diff, etc. And given our Z's noted 8 or 9 year old design many would say it should beat our Z's.

What do you think? And does anyone have real world evidence either way?

I sure would like to see a real test between the standard Z and the C7/Z51.

Who gives a ****! Worried about whos is bigger

Simple answer...NO
It's already been proven on the strip and track.

Exactly....the base C7 is a smidge faster than the base LS3 C6 in a straight line.. Improvement in handling is about 90% due to having the Michelins on there.

With an equal drive the z06 will be faster. Now with anyone driving, it maybe a drivers race, both drag and road course. They are close enough where it wouldn't surprise me to see the c7 come out on top.

even with average drivers (assuming equal skilled) the Z is easily faster ...simple numbers the Z has 40 or so more hp and is lighter still by at least 100 pounds if not more.

Lower weight and more hp tends to show up unless very unequal drivers.


And the "ediff" is likely to be like the MR shocks. Really good for the street and not so good for the track.

I agree but maybe someone can explain it over on the C7 forum. Some think their's is faster than not only the Z06 but also the ZR1.

I just drove them both on the track at Spring Mountain. The C7 runs very well and has strong torque right off idle. The Z06 no doubt pulls harder, especially from about 4000 RPMs and up. The LT1 simply doesn't have the top end power of the LS7. Lap times by the instructors are pretty much dead even- I asked. Each car has spots on the course where it's faster. They are run with stock tires, so the Michelin PSS ZP tires are part of what makes the C7 run so fast there. The Z06 had PS2 ZPs. Again, that's from the instructors. The E-differential plays a slight role and the new aluminum frame rigidity definitely is a big factor. That said, based upon what I've seen at the drag strip, most folks would run a quicker 1/4 mile ET in a C7 with the automatic trans because getting the Z06 off the line is tricky. Launching an auto C7 is pretty simple. In a roll race, it's goodbye C7- but the C7 would not exactly fade in your mirrors. By the way, the C7 seats are excellent.

Not in a straight line; perhaps on certain road courses.

Because some C7 owners are living in a dream world. When I need a laught at work, I usually go to the C7 section and read some of the posts.
Don't get me wrong, I'm starting to like the C7s but until the Z06 comes out, it's the C6Z for me....

Is it close enough to hurt the ZO6 resale value.

I'm not sure about this. Apparently it's easier to get 100% of the performance out of the C7. The new car's real claim to fame. (your granny can drive it fast). The Z, especially the earlier models, takes a more skillful driver.

Les

It's funny that some C7 owners will claim that the C7 is clearly superior and faster on track than the Z06. That simply isn't true. But egos are at stake here, so some folks must believe that even if the facts don't support it. To clarify my prior remark about both cars at the drag strip- the Z06 is definitely faster there in the hands of somebody who knows how to drive it. The C7 is just easier to drive to it's full potential when equipped with an auto.
Tough call. I don't think any more than the typical amount when a new gen Vette comes out. The C6 Z06 is still a serious kickazz Vette that's made with serious track performance in mind.

Mr. Gizmo

It will be the same difference as a c4 Zr-1 to a 1997 350hp c5 with the LS1. I had a 1991 c4 Zr1, and a co-worker got a new 97 LS1 c5 vette. He thought 25 hp extra my C4 zr-1 had at 375hp was not that much and the car mags at the time were saying the C5 was an equal or better performer than the C4 Zr-1.

I ran this guys ls1 c5 from a dead stop and from a roll a bunch of times ---It was not even close. I will let everyone guess which car was faster On a track course they were probably about equal.

Now when this same guy traded up for a 405hp c5 z06 when those came out it was a different story, especially from a dead stop. From a 40mph roll on, my 375hp zr1 could hold its own at about a car length ahead of the 405hp Z06. On a track course it was adios C4zr-1.

In some ways I think the C4Zr-1 was a much more substantial car then the C5 or My current C6z even though the old zr-1 is not near as fast my c6 z06. The C4 looks tiny sitting next to a c5 or c6 or c7.

ibleedgreen

Wrong. The C7Z maybe, but at it's price point it will make the $40k C6Z even more of a deal.

Who the hell wants a standard C7 over the C6Z? C7 will be a dime a dozen while the C6Z will become even more rare. Funny thing is I bet over the years the C7 will eventually drop below the C6Z in value.

And I will say it again, I would not even trade straight up my C6Z for a C7 Z51!

I don't think so, personally.

The Z06 is now pretty much in the "really expensive 8 year old used car" niche and is relatively impractical - which appeals to a certain kind of driver; whereas the C7 is still in the "next big new thing - with a warranty!" niche - which appeals to waxers, people who don't want to work too hard while driving, and people who trade in their cars every 3 years because they need something to brag about to their friends with. IMHO these are two very, very different buyers with rare exception.

So no, I don't think the C7 hurts Z06 resale value anywhere nearly as much as used Grand Sports probably do. I think that the Z06 value stands on its own relatively well on average because purists and track junkies will scoop them up - but it will nonetheless decrease over time because let's face it, a large portion of Corvette buyers are not so much purists as they are "next big new thing" buyers. The guys in here that will say "I'll never trade my Z06 in on _____" are purists.

It's hard to tell from surfing around. With preformance numbers close having factory warranty is a big plus.

Z has more horses and less weight.
