These charts don't reflect the weight of individual cars! It shows NO differentials for the CCB package (and Z07, which is a wash). I'm sure the CCB shaves a few pounds (where it counts the most) from the standard (iron rotor) car.

I consider the GVWR - (minus) Maximum Load calculations for individual cars MORE accurate than what is listed here. I published those previously for a Coupe, Z07, TOG, J57, 3LZ, CF wheel car (3,714 lbs) in this thread:
https://www.corvetteforum.com/forums...cf-wheels.html

Interestingly, the chart indicates the weight of the aero package to be 27 lbs. Far less than 734 lbs downforce at 186 mph.
The HTC adds 98 lbs to the weight of the coupe.
Bottom line, 99% of the C8 Z06 cars will weigh over 3,700 lbs! This is factual, just learn to accept it.

If that is true, a non CF wheel car with a FAL will weight 3780 lbs. I think thats how vast majority of the people will order the car. I'd categorize largest pool to be Z07, 3LZ, non CF wheels followed by Z06, 2LZ, non CF wheels. That second pool should be 3800 lbs. I am really skeptical that someone will order a 1LZ Z07 car but add CF wheels to it. That'd be a very expensive car without heated or cooled seats, memory function, etc.

They could offer some of the low-hanging fruit for this lightweighting package- lithium starter battery, Lexan rear window and thinned other glass, lighter seats, titanium exhaust, removed sound deadening, etc.

They did many of these things on the C5 Z06 to reduce weight; they can do it again at least as an option package.
i agree. However, GM is a very large company with a bureaucracy steep in tradition. A small change as you describe will receive a nod in time to transition to electric vehicles. I also think you described a C8 ZO6L version. An RS version should include smaller fuel tank, no trunk, manual seats, manual steering wheel controls, hardtop only, and reduction in overall size.

Ongoing constraints will most likely keep Z07 allocations artificially low for some time...Z06 will make up the majority of sales and it won't even be close.

So you are the one that started THAT boondoggle?
The GVWR minus the maximum load calculation 'trick' is quarter mile ten foot clock start on steroid :-)
I get it that you don't understand the EPA chart but c'mon...The import cars use that trick to cheat curb weights by 100 pounds or more. Why do you think the EPA weights cars??
What is the number that counts?

Think about it...two passengers two trunks... whats the maximum load again?

Methodology whooper set aside, I am simply posting weight numbers. As stated by me and others. The chart pegs some HTCs at 3800. The charts pegs the lightest C8 Z06 at 3680 in 3LZ form. Lighter than that if I show up with ten gallons in the tank and a 1LZ.

If you need to understand how it is done just ask.

I am puzzled here. The weight of the car is as it comes from the factory, with full fluids, and full tank of gas. How can there be two interpretations of this mathematical certainty and we are still talking about 100 lbs of difference? Are your posted weights as I stated or is his? I dont care how EPA tests it or door jam sticker is printed. The true weight of the car is its total weight on planet earth that gravity acts on. That is all of its components, all fluids, full tank of fuel, including floor mats but not including other passengers etc.

I give you an object, "mass" from F=ma. How do you measure mass? 99 out of 100 people will put the "mass", lets say for arguments sake its a steel solid cube, on a scale and measure its reading and report it as a result. You dont measure mass with a tiny juicebox on top or box of matches. That would be called "weight of the solid cube plus a juicebox or box of matches". The weight of the car with a passenger and cargo isn't the same as weight of the car. Weight of the car cannot include the weight of the passenger.

So what exactly is the full weight of the car with the fluids, full tank of gas, and floor mats and nothing more?

Hooray!!!!
Another C8 Z06 "How much does it weigh" thread. We certainly needed another one. These numbers have been crunched, pulverized, dismembered ad nauseum over NUMEROUS threads and posts.
And the answer is the same now as it was the FIRST time it was brought up:
ANY C8 Z06 weighs hundreds of pounds more than a GT3/GT3RS/GT4/GT4RS/GT2RS. If the weight of the C8 Z06 bothers you, buy something else.
EVERYONE wishes it was lighter. It's not. But do we really need to keep rehashing this over...and over...and over? Jeez, it is what it is. Porsche GT's are lighter...AND more expensive. Feel free to buy one if the weight is your charlemagne.

I am not here to confirm it weighs hundreds of pounds more. I just want an answer as to what its actual weight is. And what I do with my money isn't for you to decide. I may/will still choose to buy it no matter how heavy it is. But this doesn't mean I should be completely ignorant and not care about its weight.

By you, I'm afraid.
You are right...because none of you seem to be ABLE to take 3,434 POUNDs, figure out what 18.5 gallons of gas, 1 L of brake fluid, 8 quarts of motor oil, 7.5 quarts of DCT fluid, a gallon of washer fluid, 24.8 quarts of coolant WEIGH and ADD it to 3,434 pounds dry weight of a Z07 with CF wheels and CCB's, which will give the WET weight of 1ZL Z07 with CF wheels and CCB's (I am assuming that this is a 1LZ car with NO front lift)
All I hear is how transparent Porsche is..so straight from the Porsche USA website
Curb weight GT3RS: 3,268 pounds
GVWR GT3RS: 3,957 pounds
Maximum load: 689 pounds
Does that "maximum load" number look odd? Does to me. They're telling me a 2 seat sports car can carry 2-200 pound adults PLUS and additional 289 pounds of luggage/stuff? (max load of a Z06 is 423 pounds) Something seems weird but I'm sure you guys have an answer for it.

Now, you and Unhandled Exception want to know what EVERY version of the Z06 weighs, based on options/equipment/etc.
Great...I want to know what a GT3RS weighs with magnesium wheels and CCB's? Nowhere on the Porsche website does it show that, so I have NO idea HOW that 3,268 pound curb weight is equipped.

Same guys bringing up Porsche, Ferrari and McLaren, when comparing cost/value are the same guys complaining about others mentioning them..

FTR, and I said this from the debut, that using the GT3RS in any metric of comparison with the c8z06 is unfair... 992 GT3RS s an active aero car meant for hardcore track enthusiasts. It will annihilate the c8z06/z07++

What's going to interesting is when the Car and Driver Lightning Lap comes out and everyone finally has a track number. What will be the stories if the car does 2:40 or lower?

On this, I agree completely. It is (and always was) an apples to oranges comparison. Two different cars with 2 different purposes in life.

Technically, the 911's are 2+2, so maximum load of 689 lbs sounds spot on. Also, the GT3RS has nearly 1,900 lbs downforce and its springs are sized to deal with it.

I would like to know ANY trim of Z06 but officially its weight. And its weight alone, not cargo, not passenger. Just the car as a magazine would put it on a scale. Thats it. But whats important is that GM tells us what spec that weight is for.

I think a slight complication is 991 GT3RS and 992 GT3RS are very different cars. I personally always meant 991 GT3RS which is a much more apples to apples comparison. I said it numerous times in the other thread trying to compare 992 GT3RS that its a car in a league of its own.

Riddle me this, why does the heaviest most powerful car get better fuel ecomony? It's a small amount better but is it better tuning? I thought smaller size and DOHC engines got better mpg. Not that it matters but Chevy and Ford have almost 1 liter smaller displacements, less hp, significantly less tq, and less weight. You can't tell me they have more drag than Chargers and Challengers, as Challengers are pretty flat across the front end. Maybe push rod engines aren't so bad after all.

Superstock/Redeye 6.2L SC 807 hp 707 tq - 4400 lbs.- 13/21 city hw 10.2 1/4
C8 Z06 5.5L - 670 hp 460 tq - 3700 lbs - 12/19 10.6 1/4
GT500 5.2L - 760 hp 625 tq - 4100 lbs. - 12/18 11.1 1/4
