I am not trying to add fuel to the fire. I do like this car and regardless of how it performs, I will most likely get one next year. It is the only sports car I can afford in the price range.

Now that's out of the way, here is why I am creating this thread. I need someone to explain to me the performance numbers behind this car. On one hand we are told this car beats a ZR1 in a race track, correct? We also know in nurburgring, with lots and lots of straights, ZR1 is currently what? in the top 15? That's pretty darn impressive. It means this thing has to beat all the Porsche models up to 918 spyder, all BMWs, Ferraris, and so on. So fine, that's the "claim".

Now reality is, this car does 127-128 mph in 1/4 mile, people say it sort of dies off past 140 mph. I don't understand this. An M6, a big fat whale M6, with a competition package (in layman-s terms, that's 575 hp and 502 ft/lb torque in a 4200 lbs WHALE) does 126-127 mph 1/4 mile. With a $350 tune and a $1000 downpipe, it does 130 mph. Are you now telling me the Z06 will lose to the M6 or it will be a head to head race? That's not just a disappointment, in my book it just does not add up. Something somewhere is either miscalculated or misrepresented. It doesn't matter what tires this car has and how wide they are and how much aero is producing how much down force, for this car to be as good as what everyone has claimed, even in a race track, it has to perform much better than trapping 127-128 mph.

Also, if the timing is being pulled after moderate use for a few minutes, this means a person won't be able to complete 1 full lap of nurburgring without losing power. Again, how is this car supposed to beat ZR1?

This is not a post to upset people, but a genuine attempt to understand how these performance figures/claims are being created. Either GM is not telling the truth, or the car makes more power, or I don't know what else it can be.

 

Who knows what's going on with GM these days. If the car is only good for 3-5 laps, then it's laughable...

I too am concerned and curious as I am ready to pull the trigger on an A8 coupe Z07.

 

Guys, I know most of you know who this guy is, but if you don't, check out all his posts. All he does is trash the z06 in all his posts

 

Perhaps, but he's bringing up valid points, nonetheless.

 

Those m6 times you are quoting are not simply achieved.. That tune is not a real tune, its a piggy back with various settings.. 2. You cant compare a twin turbo to supercharged car. 3. I belive that m6 was running meth and race gas if im not mistaken. 4. That m6 has a dct tranny, faster shifts then a8 and m7..

The z06 has just been released a for a week.. M6/m5 has been out since 2012 and the first person to hit 10 sec just did that not to long ago. Give it time to be explored..

 

If you look back at the previous F1 seasons when Red Bull was dominating, it was frequently noted that the RB cars were either the slowest or one of the slowest cars on the straights of almost any given track. All the while, setting lap records and destroying the competition.

I think you are fixating on top speed. Give it a little while and we'll see how the lap times work out.

 

Here is what I don't understand...how many ways must a car be measured to be considered a super car? The vette clears the quarter in 11.1. That puts it up there with all but a handful of Exotic Supercars exception being the GT-R at 11.0(150k for this?). Beating such auto as Ferrari 458 Special at 11.1 126mph. Beating all the Porsches except the 911tt-s and the 918. Besting the Viper TA. The Z hits 60 in 2.9/3.0 secs which is an exceptional number for any car especially a rear wheel one. I know when it first was announced that there was to be a '15Z I had hopes of 3.2 to equal the great ZR1 but the auto trans blew that away.We now have proof of both the tq and hp numbers as well as the weight. We also know according to at least one magazine that the z has the shortest stopping distance of any stock car they have ever tested along with the highest lateral g. Plus the fit and finish of the car is outstanding...so...I ask again! What does it take? (purely rhetorical I know)...rrm

 

Bimmer fanboy not honest enough to admit he feels better about self after ragging on c7z. Which he will never own.

 

You have no idea how much I have been DREAMING about the Z06. I cannot wait to sell my M5 and start saving money. Please STOP picturing me like a fanboy, I am not. I have no reason to lie. You can talk to my wife, who is sick and tired of listening me talk about corvettes.

 

It really doesn't add up. Several cars with similar weight and hp are running 130-135 in the Qt mile.

 

GM got some people real good - all that marketing hype, deposits down at msrp or more, now this video just turned the entire z06 world upside down. Reading about easy msrp and better already deals, car seems easier to get, people considering bailing on their deals etc....

Wow and ouch !!! Always better to wait - lack of tests were the signs.

 

Yeah especially all those auto journalist that rave about the car including top gear and it really suck for GM how Stingray won car of the year and must really really **** people off that this gen Z06 is do much better than last gen z06/zr1 especially considering the price went down with inflation adjustments and the technology and performance went way up..... Yep really suck. I am going to have to cancel my 10 orders and with an M5 or a old c6 something .... NOT

 

The fact that it did a sub 1:30 at Road Atlanta on street tires, easily shows the performance potential of the car.

 

I am a long time Bimmer and Corvette guy; the OP is right. How is it that a 650HP rated vehicle coming in at roughly 3500lbs is only trapping at 127 or so while a 505HP C6Z of yesterday was trapping in the 125 mph range? Sure, the C6Z is lighter, but with 145 additional SAE certifies ponies, you would think 130 to 131 would be the acceptable trap speed given its greater aerodynamics and more ponies vs. the previous N/A model. Granted, GM cleverly said the Z was trapping at 123 or thereof back in 2009/2010 exactly around the same time the C6 ZR1 was released…remember that folks? I've smelled the marketing "game playing" trash for years.

Just think about it, back in '06, the C6Z was marketed as an 11.60's or so 125MPH machine. Many of us with some skills even got faster times than that. Then somewhere along the way the C6Z became an 11.8's @ 123mph car...funny, it was slowed down (marketing move) around the same time the ZR1 was released...which was advertised to run in the 11.40's or so at 127 if I remember correctly.

Hmmm....perhaps they didn’t want folks to say: screw that, a $45K to $55K or more mark-up for a car that is only a couple of tenth and maybe a couple of MPH faster than its N/A brother? No way! Therefore, tell the public the Z06 is much slower vs. the ZR1 and thus the justification for the price hike.

Moving forward, the C7Z is certainly de-tuned…I’ve messed with one for a few hours and it does have lots of hidden HP potential. Perhaps GM left it up to us to unlock the hidden additional ponies if we choose to.

Regardless, MPH does not win races, Elapsed Time does…the new M6’s are NOT running low 11’s stock; they are high 11’s at best. Based on proven M6 track results vs. GM advertised ET for the new Z, in the real world, all being equal, from zero to end of the 1/4 mile the C7Z would smoke the M6 or M5. Then again, I am basing it on GM’s claims…I will have to see for myself. By now I would have purchased a new Z, but a) I am not too convinced on all the GM hype, and b) I want the automatic transmission…no more stick for me. So for now, I will have to simply enjoy our customers Z06. Hey, they are not complaining, they are getting crap for free.

 

You lost some credibility on "the fit and finish being outstanding" remark. Of the few Z06's I have seen none of them had outstanding fit and finish. I know it is largely hit and miss for this but GM has to step up and improve this.

 

I also find it funny those comparing this z06 to the zr1 of old. Thats like comparing the new gt mustang against the last gen shelby then whining it doesnt do everything better. How about we compare this c7z06 to c6z06, you know, the car it replaced. It's funny you compare a z06, which is 20k cheaper, than the old zr1, and complaining it doesn't beat it at every single benchmark.

Also, the c7 interior (the part of the car where you'll hopefully spend most of your time driving) is light years better , imo, than the zr1s. This Is ultimately why I went for this car rather than having picked up a zr1.

 

You have no idea how much I have been DREAMING about the Z06. I cannot wait to sell my M5 and start saving money. Please STOP picturing me like a fanboy, I am not. I have no reason to lie. You can talk to my wife, who is sick and tired of listening me talk about corvettes.

 

Completely agree.

Also, for what it's worth, I would much rather have a C7Z06 than a ZR1. The C7Z is an amazing car, I would love to own one. That said, it speaks volumes about the Corvette fanbase that people get their panties in a bunch this much over a few races with a Viper. Talk about insecure.

I guess some of the age-old Corvette owner ***** jokes ring true.

 

It is not me picturing you...look at your avatar and you are the one bringing up M3, etc. I hope you get a corvette in the future. BTW, the local bmw dealer asked me to test drive an m5 twin turbo a few months ago. I drove the **** out of it and came away thinking in was a nice performance sedan, my wife thought it was cramped inside. Not even close to my c751 in any performance measure.

 

Of course it's not even close. One of them weighs 4400 lbs, other is 1000 lbs lighter.

But one can carry 5 adults and has butt massaging and ventilated seats with an entire interior covered in either leather or alcantra the other is well, you don't need me to tell you.

I know compared to a typical american car like a suburban or an explorer an M5 feels "cramped up", but to me it's actually plenty big. It's the perfect family car. I cannot carry my wife and kids in a Z06 and still get some enjoyment.
