Interesting.
At 3455#, that automatic, 3LT Z51 car only weighs 80# more than this non-Z51, 2LT M7 car. I thought Z51's were 146# heavier (plus the additional weight of A6, and in this case, 3LT).

You can't compare a base zero optioned C7 M7 at 3298 pounds curb weight to a Z51 A6 with a higher trim level and other options.

What we don't know is what a base Z51 7m 1Lt with zero options weighs(according to the car's label on the door. That will tell us the difference between a Z51 and a non Z51, both being 1LT's with zero options.

On the C6, the A6 weighted ~122-125 pounds more than the M6, but I suspect that the M7 weighs more than a M6, so the delta would be less on the C7. Why don't you remove a A6 from a C7 and remove a M7 from a C7 and weigh them on your scales and tell us what the delta is.

 

You disputed my claim early in this thread that the weights published by the magazines were for the actual test car (even when I substantiated it with facts on a number of their testing protocols). You even went so far as to claim that the 3444# number in magazines (and there have been three different weights published including 3444#, 3404# and 3386#) did not "surprise" you, even detailing the items that would add up to 146#:
So now, using the GVWR door tag theory, there are 3LT, A6 Z51's with NPP (and I believe at least one with MSRC) that weigh only 11#, 22# and 23# more than a no-option Z51 M7 (or is it the loaded magazine test cars with M7's?)?
The M7 weighs 11# more than the M6. An A6 Z51 car should weigh ~111-114# more than an M7 Z51 car (otherwise similarly optioned, of course). So if A6 3LT Z51 cars with NPP weigh 3455#, then M7 3LT Z51 cars should weigh 3341#-3344#.

A little late in posting this,

But here are the door tags from VIN 648...

Z51
2LT- suede inserts
Auto
NPP
MRC

 

Hard to believe no one knows the weight of a Z51.....is it that bad?

 

I am sure when the brochures come out there will be a weight. I think GM wants to keep it unknown for as long as possible.

 

At first the weight penalty of Z51 was estimated at around 80-90 pounds. Later some people started saying more like 150 pounds and that figure caught on. But based on recent door stickers it looks like Z51 does add more like 80-90 pounds as originally estimated. When we finally find 2 identically optioned 2014s, one with and one without Z51, we can compare door stickers and we'll know the exact weight of Z51

 

That describes the car I have on order. I will put it on my wheel scales and tell you what it weighs, on each corner, when I take delivery.

 

Okay I'm confused, these door tags that are being posted are showing 3900+ lbs??

 

I believe you subtract cargo weight of 525 lbs from that figure.

 

That is true.

I started copying down door sticker GVWR's on CTF cars last June. All were Z51's except the first one, 000032, a base car with 3LT, auto, and chrome wheels:
000032 - 3924#
000031 - 4002#
000012 - 4003#
000011 - 3996#
000085 - 3995#
000134 - 3993#
000099 - 3992#
000181 - 3989#
000063 - 3983#
These Captured Test Fleet cars were all that were available to check until I got my own on 9/23. I haven't seen any more ordered cars to check yet. I'll post my own figures below.

Note that the "Gross" Rating in the door includes the weight of the car as it rolled off the line, + a 525# load, + the fluids the dealer adds (a full 18.5 gallon load of gas and about a gallon of windshield washer fluid).

My "Certificate of Origin for a Vehicle" (MSO) finally arrived at my dealer a week after I took delivery so I picked it up today along with a copy of the invoice. I also had a service advisor print out a copy of my vehicle build. Although I ordered a base car there are some items in 2LT that add weight: the articulated seat features and the cooling motors, HUD, and NPP. Nav shouldn't add much.

Here are the various weights shown:
"3252 SHIP WT" is listed on the invoice
"3252 SHIPPING WEIGHT" is listed on the MSO
"3899 G.V.W.R." is also listed on the MSO
"3900 LB" is on my door sticker
"1769 KG" is on my door sticker
"1,770 Gross Vehicle Weight" is listed on "View Vehicle Build"

The shipping weight listed on the MSO is what GM declares to government agencies and the shipper that the car weighs when built.

Out of curiosity I dug out the MSO and invoice from my 2005 2LT 6-speed Z51 coupe. It shows 3174 shipping weight, only 78 pounds less than my C7. And later C6s gained more weight with the TR6060 trans and beefed up steering. I feel better now knowing that C7s really aren't as porky as I thought. And for what it's worth it has a lighter "feel" when driving than previous Vettes.

As more and more cars' door sticker weights or MSO weights are posted, I think we'll find that Z51 probably adds less than 100 pounds.

Note: When issuing a title some states print the shipping weight from the MSO on the title. Florida does.

 

Please do, that will be interesting
Also please let us know the gross weight rating from the door sticker.
And ask the dealer to tell you the SHIP WT printed on the invoice. Maybe he'll make a copy of the MSO for you, SHIPPING WEIGHT is on there too.

Congrats on your new Stingray, when is it due?

 

The invoice for my C7 indicates SHIP WT: 3339. From other threads, we know that they are shipped without much gas in them at all, so that's pretty much just the car.
