Corvette C7 Top speed?
 

Hey,

I may have overlooked or something but I just can't seem to get a definite number on whats the top speed of the C7.
I really hope its not limited to 155 mph like the ZL-1 vert and all other stupid cars. I certainly can't bare that, its annoying.


So anyone has the final number ? :/

plus the Auto will come with a launch Control right ?

Wait how does that work?
Like from what I know (not a vette fan) GS is a level above the base right?
So if its lower the base C6 then how can it be equal to the GS. Correct me if I am wrong please :)

And that is based on what?

Let's see the C7 has 25 more HP, better aerodynamics, less drag, and you think it is going to have a lower top speed....

The GS is heavier and less aerodynamic then the base with the same horsepower. It is a simple power to weight ratio thing plus aerodynamics.

How does top speed matter? Does anyone actually do it? If so, where? On a drag strip you don't. At a track you don't. On the street you don't. For the life of me... other than bragging... I have NEVER understood top speed as a meaningful stat.

It's a very important statistic if you're trying to justify to others why you bought a base skinny body C6 instead of the wide body GS. It's FASTER!!!!!!!!!!!!.........top speed, that is.

Because generally a car with a higher top speed has "longer legs" i.e. that 50 -120 jump when you need to pass a couple of cars. It is also indicative of the power of the motor, aerodynamics and weight.

I am thinking about 150 I would lift and not even think about it...that is my top speed.

Good points.

191 ;)

I hope it's higher than 75 :leaving:

:iagree:

Non-z51 may be higher than the Z51 due to gearing.

GS owners who are honest with themselves have no problem with the fact that the base C6 has higher top speed than the GS.

Base C6 owners who are honest with themselves have no problem with the fact that the GS will accelerate quicker than the base C6.

Z06 owners who are honest with themselves will have no problem with the fact that the Z06 has a top speed higher than a base C6 and will also accelerated quicker than a GS.

To be quite honest in all this top speed nonsense I just traded in my '12 coupe for a '13 GS and I could give a rats ass which one was faster. And should I ever decide to get a C7 it would apply there also. Could care less. Never going to use anywhere near the power any of the cars are capable of producing ( at least in my eyes ).

More than 193 if it does not lift off ;-)

A) Where do you come up with only 19hp difference?

B) Where do you come up with higher cd?

Cd is not the same as Cda

And C6 GS owners who are honest with themselves have no problem with the fact that the Base C6 LS3 Z51 will accelerate quicker than the GS.:thumbs:

What causes the extra drag? I thought the GS was pretty much the same in design with the exception of the side fender vents and the hood scoop.

And why would chevy build a mid model that is actually slower the lower model? That doesn't seem to make sense.

When it came out, the GS did 0-60 in 4.2 sec, whereas the Z51 did it in 4.1.

Any engineer will tell you that marketing justifies a lot of apparently nonsensical moves. I know a guy who called it marketengineering. People wanted a wide body, so they got it.

Simply just all the extra weight of the GS. Remember the GS is the replacement for the base LS3 Z51's. They have the same horsepower but with all the goodies GM added to the GS it added weight and the wide body is less aerodynamic the then narrow body car. The power to weight ratio gives the advantage to the Base Z51. And even the old LS2 Z51's might give the GS a good run for the money being they were even lighter then the LS3 Z51's I think that match would be very close.

:iagree:

You forgot to mention more gears… 6th isn't overdrive anymore!!!

(a) C7 is 450 vs. 430-436 in c6 (depending on whom you are listening to).

(b) The GS wide-body is by definition less aerodynamic than the base 'vette. There's a discussion in All Corvettes Are Red about why Dave Hill wanted a 17/18 tire setup (vs. 18/19) for the C5, and aero was a big part of it. He wanted to get the Cd below .30. Keep in mind, a major goal for the C5/6/7 engineering teams is to avoid the gas-guzzler tax, so aero counts big-time.

Correction. The C7 is 455-460hp. Not 450.

I opened my base 06 C6 up to 150 with ease on the eastern plains of Colorado. Pulled hard to 150, I slowed down only because I was coming up on traffic. Hugged the road and the only way I knew I was going that fast other than the speedometer was the stripes on the road whizzing by. I have to believe the C7 with more power, better aerodynamics, and narrower tires wouldn't run much faster than my C6.

btw I always do the speed limit but when I could see from horizon to horizon, felt the need to open it up!! Gotta love the power of a Corvette!!:auto:

Depends on gearing but 190+mph sounds about right.

It'll be faster than the base C6 and definitely faster than the C6 GS. The widebody design had more downforce and also more frontal area and drag than the base C6.

The C7 won't have that problem. I doubt it hits the high 190's like the C6Z though.

Doesn't really matter IMO. I like the 60-130 sprint much more. For measuring straight line at speed performance.

6th is still an overdrive.

5th, 6th and 7th are overdrives.

Correct. :thumbs:

True, but I didn't mention that as the C6 Z51 hasn't been available since 2009 as the 2010 GS replaced the earlier Z51.

Funny, we have a long causway over two rivers (really more like swaps were they meet) that is over 3 miles long. There are no shoulders on either side of the 2 lane split highway and large trees between opposite directions. When there was no traffic and as the C6 approached about 130 mph and actually was more stabile, the thought of "what excuse do I use if there is a "Bear in the Air" limited my maximum speed! The "I didn't know how fast I was going" doesn't work!! It's go directly to jail and loose your license for 12 months that limits my speed. The 165 mph I reached at the Richard Petty Driving School was fast enough for me! I'll stick with 0 to 60 blasts and off ramp G measurements for the C7 on order!
One last comment re a previous mention that weight is a factor controlling top speed, it is not. Cd and HP are controlling. Weight just defines how long it takes to get there!

:iagree:

This is what limits my speed too. I'm worried about 2 factors:

1) Other drivers appearing out of nowhere or animals stepping out into the road.
2) Johnny Law.

You can do top speed runs on some large dry lake beds in the Western U.S. I've done it, although not in a Corvette yet. Your car is filthy mess afterwards with the dust, but at least it is legal.

If it is less than 186 mph the C7 is a failure on all levels.

Oh, you left out one other one....
Z06/ZR1 owners who are honest with themselves have no problem with the fact that the ZR1 kicks the Z06 in every catagory you mentioned......and more. :lol:

I live in Saudi Arabia and travel a lot.
Every weekend, I visit my parents which 400 kms away from my house. The roads here are just amazing so its pretty easy for me to hit the top speed of my car (GCSRT8). Thats why I wanna know how much it is! :)

This is a joke right? If this is a serious post, then you are :crazy2: If you are joking then.....:thumbs:

It should be a little above the current 186 mph. That's where substantial hp increase is mostly needed, and it didn't happen.

I am hoping it is. I don't want a 155 mph limiter on my car, its really annoying to be honest.

But its really weird they didn't release this number :S

So are you saying that if the C7 tops out at 187 it's a failure on all levels except top speed? Or just havin fun?



.

Because the car isn't done yet.

185-190? Who gives a fk? You aren't going there anyway, are you sport? I don't think you have the ballz, or the $$$$.

I think you didn't read my previous post.

I am from Saudi Arabia and we have miles and miles of open straight highways to drive as fast as we want. I have done 300 Km/h run in a R8 before and its not as scary on 4 lane highways.

Plus how is $$$ related to hitting the top speed ?

In your eyes only. Don't include the rest of us in your delusions.

:rock:

Guys, he's just kidding. It's hard to detect the sarcasm, but he's cracking a joke about all the haters that say dumb things like, "It's heavier so it's a complete failure," or, "only 25HP more, so it's a complete failure."

:thumbs:

My magazine is faster than your magazine.

What magazine do you subscribe to because I want that one too.

Which ever one is at the barber shop the day I get my hair cut.

But, if anyone is really serious about seeing who's got the fastest car, top end, then they should arrange to rent the private 8 mile oval test track in Ohio for a day. Get 100 people at $500 each to show up and we can see if their C6 GS can hit 185 MPH, their C6 LS2 can hit 186 MPH, their C6 LS3 and their C6 427 Convertible can hit 190 MPH and their C7 LT1 can hit 191 MPH(????)and their(my) C6 Z06 can hit 198 MPH and their C6 ZR1 can hit 205 MPH.

I'll be first in line with $500 for that fun filled day. But, if you can't afford to eat your car if you hit the wall, don't show up as your insurance carrier does not cover you when on the track.

Winner gets treated to a Happy Meal at McDonalds.

Can anyone tell me what the 60-100 time of the C7 is?

I heard you were basically bald..............:D

No, but I can tell you that Road & Track said the 1965 396ci/425hp could accelerate 50-70 MPH in 2nd gear in 2.5 seconds.

damn, I thought the 10" long comb over hid that.

I always thought top speed didn't matter until I ended up in Germany with my C5. Then, top speed became a huge factor since I'm basically a very competitive driver. With mods, I saw my 02 at 183 and it had more, but that was enough to beat an AMG on the autobahn and a Ferrari 365GTB on the autostrada.

I know, very few will ever see top speed in their Vettes nor will they drive the autobahn, but there is a bragging factor in knowing that your car would walk away from a Porsche, or BMW at top end. Nah....it won't be the fastest, but it certainly won't be the slowest high American performance car.

totally meaningless for 99.99% of us.

I know the feeling... :thumbs:

The tires will determine if there is a limit. I highly doubt that will be the case, since top speed provides some bragging rights for a sports car (even if there is hardly anyone who comes close to reaching it).

The flat torque curve in the C7 should help the top speed. A peaky engine can have trouble getting up to speed unless the gearing is perfect, while the engine that pulls harder through the rev range can get to that sweet spot where max horsepower and top speed line up. The increased down force will likely provide more drag at high speed. You don't get down force for free, it increases the drag as well as the rolling resistance at speed. Gearing is also a big factor, but it's not likely that GM used top speed as the determining factor for picking ratios (if they did the car would top out right at the top of 7th gear, which it will surely not).

Will it be any faster than the C6, not likely (top speed for the C6 was typically listed at 190mph). But I bet it will be more comfortable at the limit, even though very few people will ever get there to experience it.

I think the C7 will top out at 193

Even when top supposed top speeds are posted it will take a perfect storm to get there. Better yet has anyone on this forum taken a bone stock car to the suggested top speed of said vehicle? I know I haven't and I've tried.

I know I never will. I've seen 165 in a blown C5, and 150 in a stroked and blown c5 with gears. Had no desire to go faster than that even though both cars had ALOT more left in them. :leaving:

With peak power being relatively very similar to the C6 I believe it will come down to drag/aero factors, and whether the C7 is truly more efficient in that regard, at that kind of speed, than the C6. Remember you need exponential-like increases in power to get relatively modest top speed gains the faster you go, as aero becomes the predominant factor to overcome.

I read somewhere that a Veyron is using 500hp to push through the air at 200mph. To get the next 50-60mph requires another 500hp.

As far as "marketing"; if it is faster than the base C6, they will list a number. If it is not, they will take the GS approach, and.. not list a number. :)

Why does it matter? Same reason any of the performance metrics matter, so we can bench race them on the internet of course.

Justin I too have reached low 160's in my ACR on a track and around 182 in my Murcie which is the fastest I've ever gone. Funny that the 182 did not feel as fast as the number makes it out to be, felt more like 150-160 which I've been numerous times. Maybe the Lambo was just so well planted and stable it felt slower I guess.

Joe's in a good mood this morning.

Well if the C6 base Coupe can reach 190, the base C7 with better aerodynamics, more HP and torque.... should exceed 190 by a few mph. Maybe 195?

Can I get some fries with that?

I believe the exact definition of "better aerodynamics" will be the deciding factor. The cd of the base C6 is already very slick.

If they are saying that "better aero" on the C7 is, say, more downforce at 130, it could be quicker around a track, but detract from top speed.

Exactly correct. My ACR produced 1000lbs. of down force at 150mph yet the standard Viper coupe produced only 100. The ACR had a top speed of 182 and the GTS a little over 200, not exactly sure of the number but I think it was 202.

202mph out of the base 450hp GTS? :eek: Would be very impressive considering the similarly powered base C6 is advertized at 190 and is supposed to have less drag than really any of the 90's cars.

Pulled this from Top Speed article.

"While the engine has a dual personality, where one sips fuel and the other fires all eight cylinders like a madman, which — thanks to the weight savings of the new aluminum chassis, and a carbon-fiber hood and roof — warps the ’Vette Stingray from 0 to 60 mph in under four seconds and to an anticipated top speed of 180 to 190 mph. Even in the base trim, the Stingray packs a punch, so imagine the personality of its twin brother, the Corvette Stingray Z51."

You are thinking of the Gen 2 cars, I am referring to a Gen 4 GTS. I was correct, it is
202.

https://en.wikipedia.org/wiki/SRT_Viper

Who cares 99.9 % of the people on this forum will never try it, it will be rated above the base C6 of course.

I'll personally get you a double order of fries if we can pull it off.

All spoofing aside. I would really like the opportunity to see if I could hit the GM claimed top speed of 198 in my Z06. $500 is chicken feed(half the cost of the Museum delivery) and driving your car at it's top speed would make the museum delivery look like attending a cooking class to learn out to make french fries.

He can legally go that speed in his own country.

I was glad to hit 175 mph a couple of times in the California mountains.

I hit 198 MPH on the Tail of the Dragon in North Carolina passing the sport bikes in the switch backs.

First liar always loses.

So you lose. Because I didn't lie. There's nothing incredible about what I did. Will I do it again? Probably not.

I care! I think many others do too! It is not just a matter if you will ever get to do that top speed. It's a matter of knowing that it does have that capability. Call it bragging rights or whatever...

Common Question to Vette Owner: How fast will it go?
Common Answer to Question: It's rated at 186mph by GM.
Next Question: Have you ever done that?
First Lie: Not quite, but I was close!

Oh come on, tell us more. Some of the fastest driving I've seen in the US was when I crossed Iowa some years ago. Do you let these guys throw dust at you? :D

I'll let the manufacturer state the top speed. I think its funny how forum members can even argue over this topic...

Joec5 is of course the man of the hour at 198 mph in his stock z06 ..

Jerri I think Joe said that he would like the opportunity to see if he could hit GM's claim of 198, not that he achieved it.

Of course, nothing could be easier than reaching this level of speed. I knew I was being somewhat of a bad boy for doing it. But I was really shocked when I looked at the law afterwards. That's really what sent shivers down my spine.

Spring Mountain? The All C6's vrs the C6R? April 2012:eek:

If that's the case, then I withdraw post 45.

His mastery of the clutch pedal is such that it doesn't choke in the 19.8 mph trips to the church.

You better be really sure your tires are properly inflated VS the temperature of the air and track. I think one of the major magazines stopped top speed testing when one of their writers died. Things go badly quickly at high speeds.

I would have believed joeC5 did it on a track as he described. Im sorry to hear he was embellishing...I enjoy the fact that these cars are capable of exotic car performance and top speed...

I said very clearly in my post that I would be first in line with $500 for the opportunity to drive my Z06 at it's GM claimed top speed of 198 MPH on the 8 mile oval track in Ohio if 100 people would get together and rent the track for a day..

Now you tell me what I embellished.

I did pay $450 for the opportunity to drive my Z06 on the Daytona International Speedway but a Z06 can't reach the GM claimed speed of 198 MPH on that 2.5 mile oval.

How much have you paid to have the opportunity run your C6 at high speed on a Super Speedway? There are highways that lead to the tracks, so it's not necessary for you to live next door to them. I live 560 miles from Talladega and 1115 miles from Daytona Beach.

ZR1 didn't need the perfect storm, been done numerous times from those who are brave enough, unlike the GT500 which failed again and again and again....

Watching a complete 24 hrs of Le Mans made me think twice with all its safety car interventions for petty things like oil on the track. Yup, what if I hit some oily patch?? Yikes. :willy:

Real world top speed at the Texas mile last spring.


02 Z06 TT ran 216mph
08 Z06 nitrous ran 215
06Z SC/meth ran 208
06Z N/A ran 204
09 ZR1 stock ran 190
2000 coupe N/A ran 181
03Z N/A ran 198


The N/A cars may of had some bolt ons and engine work which weren't listed on results

I'm not sure what to make of this. There's huge acceleration involved here. They start from 0 and have a little less than a mile to reach these figures. Interesting anyway.

The one mile run is not top speed. I would estimate it would take 5 miles or so to top out a stock Corvette. Now a motorcycle, that's a bit different. I could run my bike up to nearly top speed in a stretch of less than two miles. Tough to find a straight stretch long enough, and without possibility of farmers pulling out, to run a car up to top speed. So when we talk about why nobody does it, it's not just about bravery. Very few people have a location that would provide an opportunity to even try.

5 miles?? Lol I don't think you need that distance to top out. I'm not a racer so I haven't a clue.

Point of the post was real speed, we all guess at what a car can do, it's pretty tough to reach 190-200 mph in a stock Vette no matter what the year.

Seems most of the mile runs the vettes never get outta 5th gear, is it really goin to take 4 more miles to redline 6th?

I've got nearly 100 passes thru the Texas Mile split b/n my Z, my ZR and my Callaway.

You won't hit top speed at the mile as you don't have the room. I honestly don't know how much space you'd need, but I will tell you that at 185 mph real estate disappears pretty quickly, and incremental mph gains are tougher to get (i.e. they happen more slowly). So it might very well take a good 4 miles to top one out.

As to gearing, you never see 6th gear in the factory stock vettes at the mile. And depending on the model, you wouldn't use it for top speed. For example the Z tops out in 5th as 6th is too tall of overdrive to use, but the ZRs with the original gear set (in later years was optional gear set) top out in 6th gear.

Yes, it takes quite a distance. Try it and you'll see. It does not take a real long time, but as you can imagine you burn up distance fast at 180mph. Even if it only takes one minute to pull the last few miles per hour, you've already traveled 3 miles! Those who only take their cars up to 160 seem to think that the acceleration will stay constant, but it slows considerably as you reach the top end, and can take quite a while to eeek out those last few miles per hour.

To attain top speed in a C6, you'll only use 5th gear. 6th is too high and you would never pull the shift. The C7 should be the same since everything I hear indicates 7th is just another overdrive over 6th.

The C6 ZR1 is the only one which requires 6th gear to reach its top speed. All other six speed Vettes before it do their top end speeds in fifth....sixth is just a highway gear. Good for loafing along the interstate at low engine rpms once up to speed.

Be my first time there this fall, hope to see you there. Personally never been past 140 and that was on a VR 750 bike.

I'm goin just to experience the high speed and actually see what my car will do in a mile.

I've been told once you hit 150, mph gains are slow. My car is not built for high speed runs or for the best mile time.

You'll have a great time. It is a well run event, and definitely worth doing. The world is a different place past about 160. A good place, just different.

It's fun to run the event, and it's also good to see the machines that roll in for it. You'll see some wild rides - e.g. Lambos with 1600hp to the wheels, etc.

If you like bikes, they also have a motorcycle class, and there are always many top bikes there.

Except for the ZR1, all C6's(M6) reach their terminal speed in 5th gear(and still have some engine RPMs left, but they run out of horsepower).

My Z06 runs out of horsepower at 198 MPH(according to GM) and it will reach that speed at approximately 6100 RPM in 5th gear. The Z06 still has another 1,000 RPM before it hits it's rev limiter. That's equal to 230 MPH in 5th gear. If you shift the Z06 into 6th gear at 198 MPH, the car's speed will decrease, as the engine's 4300 RPM is so low, and the gearing is working against you, that there is not enough torque at the rear wheels to keep the car up to speed it reached in 5th gear.

Once I shift into 5th gear at 6800 RPM (to make sure I don't hit the rev limiter) at 158 MPH, it takes a long time and distance to keep accelerating.

If I had the ZR1's .81:1 5th gear in my Z06 I would still reach the same terminal speed (198 MPH at 6900 RPM) in 5th gear but I would reach it in a shorter distance.
