This is a point of annoyance, they claim that this car has been in the works for years...this engine already existed, the chassis already existed, the rest is bolt ons and tuning. Yet, GM hasn's posted Ring track times. obviously they are having a problem getting a ring time that validates the price and hype. So, they must be going back to do some more major changes $$$

Maybe they were just there testing..... They have already stated they are not done developing the Z/28. |

That's the issue, given the specs and parts are so great and such a big change as advertised, there isn't much more to change unless you start replacing panels in cf, balsa wood, or plastic. Not much more time to squeeze out. Why the long delay after the car hit the track and hit it hard. Something doesn't add up. I want this to be a sick ass car. But even stripped down of weight, there is no way to come near the halo cars. Color me dissapointed, so far.

Who cares if the Z/28 is faster than the ZL1 or Z06 on the track. I guess it better be, right? That's it's purpose. Some ZL1 and Corvette owners need thicker skin IMO. If they made a track only Vette of course it would be faster and no way the Z/28 will best the C7 Z when it comes out. If they put different equipment on the Z/28 or ZL1 or of they are modded of course the performance would change. Lots of argument for no reason IMO. Each car has its place, each car beats others in certain areas. Can't go wrong if you ask me.

Nope. At speed your car is fighting air, not lbs. Same car, same basic shape, HP matters. And as far as the guy who said the vette had lift, the vette also has much, much less drag than our box shaped (because they are retro) cars. Look across many diff manufacturers, drag determines top speed, a lot more than weight. Any person who has taken a z06 to 190, will tell you how it goes from 100 to 175, with the effort it takes a Camaro to go from 20 to 70. After that the Camaro has a bitch of a time fighting drag. There is a video of a z06 with minor mods just smoking a zl1 with some big HP. The zl1 guys said the z06 must have had more mods, nope, the shape of the car is the trump card. The z28 will have corner advantage and exit speed on the zl1, as far as "smoke it everywhere"....doubt it

We can all agree that both the Z/28 and the ZL1 are faster around Milford than the Z71 can't we? All different vehicles with different goals.

Yep. There will have to be plenty of loooong straightaways for the zl1 to try and make up ground.

Power to weight question
Hi all, my first post, and a little overdue. Got my 2013 CRT ZL1 coupe last August after a lengthy wait. (Killed me as I live about 4 miles from where they are built and watched them drive by for stripes all the time
Anyway, love the forum, and just had a question about the following: Quote:
505hp/3800 lb = .1329 Z28 Just wondering where you got the power to weight ratio information from GM... I have heard the z/28 would be about 3800 lbs. To match the ZL1, the Z/28 would have to weight about 3590 lbs. 505hp/3590 lb=0.1407 That would be quite a diet Anyway, can't wait to hear how she really goes. My Z is a blast, but there's no getting around the weight... they are a heavy car, and unless it's pretty hot outside, they can overwhelm the tires pretty easily trying to put the power down. The Z/28 will be a very interesting comparison. PS for the vette guys: 505hp/3175 lbs= .1591 Z06 .... and for the bike guys my ducati 203hp/407lb = .4988 !!! (Get's worse with my fat backside strapped to it but still... We are lucky so and so's aren't we. Last edited by ZLFUN; 05-17-2013 at 09:13 PM. Reason: typo |

I prefer pounds per HP. We still don't know the Z/28's weight but it could be as low as 3,700. Also if we're talking RWHP the LS7 is as high as 480+ That's 7.7 lbs per RWHP. That's quite awesome.
