Roll races are MORE about the car and LESS about the driver. I've seen the hellcat in both forms take down LT4 Z06s and CTS-Vs. The videos are all over the Internet. Can I validate them with absolute certainty... No, but with enough of them available it certainly does seem to show that the hellcat defies all the laws of the Car Gods.

I understand where you are coming from and yes, Hellcats have waxed many Z06s etc - but many Z06s have waxed the HC as well. It is often a driver's race.

And that is racing a 4500 lb alleged '707 HP' Challenger.

So - the HC is definitely underrated HP-wise. It is putting out closer to 740-750 based on numerous dynos which is why it seems to be able to defy physics.

I am sure that on a given day at the same track with equal prep and with the same driver in both cars 100% stock, a HC vs Z06 challenge will go to the C7Z. It won't run away and hide from the HC but it should beat it heads up.

So, for the G6 ZL1 to 'beat' a C7Z it needs to bring more to the table than just 640 HP - a lot more. I'm not saying it is impossible but it won't happen with only a 'measly' 650 HP either.

But I DO hope it gets the grunt it needs to do it! I would love to see that happen.

at a drag strip the 60ft time is important , and if the ZL-1 can leave harder off the starting
line (weight transfer) A10 trans and gearing ........it just might , only time will tell,

[EE7]

The Z06 has a lot of drag acting against it. It is a track car after all. The ZL1 won't have any of that. The ZL1 has weight, grip, transmission, and aero in its favor.

I'm not sure what you mean by 'drag'? Do you mean downforce that equates to drag? If so, that issue arises with the Z07 Stage 3 Aero package and that is an option.

Yes, it will limit top end speed and does create additional drag but I believe the drag coefficient for the stock C7Z body is still less than that of the Gen 6 Camaro/ZL1 due to the smaller frontal area and lower height.

So, I don't see how the ZL1 would have aero in its favor vs the C7Z?

And weight is your enemy in racing. While yes, it does assist in grip in some situations, weight is a very negative effect.

Even though I own a C7, I would enjoy seeing the new ZL1 take it to the Z06 if for no more reason to make GM create a better Z06. And, given that there is a mid-engine Vette coming soon with more HP than the current C7Z, I would speculate that the idea of having a ZL1 with more HP than the Z06 model (and the new mid-engine is not going to be a Z06) will be an easier pill for the Corvette Team to swallow.

We can only hope!

Isn't there a few Z06's with 10.4's and 10.5 stock passes? Call them " hero run's " or not but I don't think there's any hellcat's with those number's until drag radial run's.

Yes there are a few C7Z's that quick. And a lot of high-10s bone stock according to the forums.

there is no doubt that the C7Z is a sick quick car.

[Marine Corps]

The 2017 ZL1 will be much faster than the base Corvette or Grand Sport. They're rated at 460 HP. The ZL1 is rated at 640 HP. Unless I read it wrong.

ZL1 features pretty aggressive aero, too...but it benefits from the use of a functional wing, rather than a wickerbill-style spoiler. The former produces downforce without as much drag.

Figure the 0-60 difference between the Stingray and the Camaro SS is about .3 second....the difference between the Z06 and ZL1 should be similar...which suggests something like 3.2-3.3 0-60 for the ZL1...Which is faster than the base Vette and the Grand Sport.

[BaylorCamaro]

Not sure why people are surprised that a supercharged ZL1 is faster than a N/A Stingray in a straight line.

Mind boggling isn't it? Lol. "Omg, how can the c7 zo6 be faster than a c7 Stingray / GS / Z51???"


One thing I am curious of is the c7 aero vs '17 ZL1 aero comparison data. I did watch an interview with the aero guys worked on the ZL1 and it definitely makes the SS look like it doesn't have ANY aero haha. They seem to have outdone themselves once again and that is just the ZL1, Z/28 even with camo looks batshit crazy!

But what I am curious of with aero, especially is at high speeds and not the 0 mph+. Gen6 SS vs C7 z51, there is a MASSIVE difference that you can feel around 120 mph and you can definitely feel that the c7 has a MUCH better aero and can flow through much much better where as the camaro is fighting the air.

Frontal area. The Camaro has much more...really not much you can do to alleviate that.

Ask and you shall receive (sort of). Tadge (Corvette lead engineer) explained the C7 (base, Z51 & Z06 (stage I, II & III) aero properties)

Explained here

The summarized version:

C7 (non Z51):
Drag Coefficient: 0.30
Lift Coefficient: 0.20
Front Area: 2.02 square meters

C7 Z51:
Drag Coefficient: 0.35
Lift Coefficient: 0.03
Front Area: 2.02 square meters

Z06 (Stage 1 Aero):
Drag Coefficient: 0.35
Lift Coefficient: 0.03
Front Area: 2.10 square meters

Z06 (Stage 2 Aero):
Drag Coefficient: 0.40
Lift Coefficient: -0.152 (makes down force)
Front Area: 2.10 square meters

Z06 (Stage 3 Aero):
Drag Coefficient: 0.50
Lift Coefficient: -0.279 (makes down force)
Front Area: 2.10 square meters

Basically a Z51 & Z06 Stage I make nearly neutral lift (or no lift)

[Zeke.Malvo]

I don't think the ZL1 will be faster than a C7 Z51+ around a road course. Otherwise, what would even be the point of a C7 if the ZL1 does everything better at basically the same price point. I don't think GM is willing to crap all over their own halo car (corvette).

[EE7]

I think I remember reading somewhere that the ZL1 was bench marked against the outgoing Z/28. If this is the case the ZL1 will be faster around a road course than the vette. The vette is nearing the end of its life cycle. GM is thinking ahead a couple of years to the new vette.
