Thanks to CorvetteForum.com member Telepierre for sharing this printout showing the Gross Vehicle Weight Rating for the 2023 Corvette Z06. The chart is broken down into both Coupe (1YH07) and Convertible (1YH67) models, and we can make out some of the options the car was tested with, including the J57 carbon ceramic brakes, Z07 Performance Package, and T0G/T0J aero kits.
The chart lists the EPA’s Gross Vehicle Weight Rating, which is much different than the dry vehicle weight. If you are looking at the lowest weight rating being the 4,021 pounds for the Coupe and thinking that is high, it’s because that weight includes 300 lbs that would simulate the driver, passenger and cargo. Without the mandated 300 lbs, the dry vehicle weight is 3,721 pounds.
The Convertible model comes starting at 4,119 lbs (3,819 lbs dry), with the maximum configuration weighing in at 4,146 lbs (3,846 lbs dry).
It appears that none of the vehicle weights included the carbon fiber wheels, which have a weight savings of 41 lbs over the aluminum wheels.
We go back to our conversation with Vehicle Chief Engineer Josh Holder, who told us at Carlisle that the Corvette team intentionally split the EPA fuel economy testing into the Coupe/Convertibles and those with aero vs non-aero. That resulted in the gas guzzler tax being $2600 for the standard Z06 versus $3000 for the Z07 Aero kits. That would explain why the EPA chart is based on Coupe/Convertible models and aero vs non-aero cars.
As compared to the C8 Corvette Stingray, the dry weight of the Z51 Coupe came in at 3,647 pounds as tested by Car and Driver. That’s only 74 pounds difference from the Z06, which is wider and has larger tires. They came to the conclusion that the switch to the mid-engine platform added an additional 200 lbs over the weight of a similarly equipped C7 Stingray.

Too heavy for a Z06.
300 pounds for Corvette driver AND passenger?? 🙂
I wouldn’t have guessed a nearly 2-ton curb weight based on the Z06 Nurburgring video I’ve seen. I’m really looking forward to a Porsche 992 GT3 vs. Z06 standoff by Road&Track or other… Or, even some Z06 lap times from VIR, Road Atlanta, Nurburgring, etc… Since it’s going to be a while till I have my own, at least I can enjoy the articles…😉
The Corvette blogger is using wrong terminology . There is dry weight, curb weight and gross weight. Dry weight for the stingray coupe is 3366 lbs, for the Z51coupe is 3408 lbs that is with no fluids. Curb weight is 3535 for the coupe, 3577 for the Z51 coupe and the vert is about 100 lbs heavier. You can add 300 lbs to these #s for gross vehicle weight which is for 2 people and luggage. 3721 curb weight lbs for a Z06 is pretty good.
Wow, kind of a friggen tank! It’s going to need all that power to move it past the competition. Speaking of which, when is the ZO6R going to show up to spank some German and Italian entries??? I watched Fuji, what a bum deal. Never moved from last in class, looked like he wasn’t even trying most of the time, I could only stand to watch small parts. They seem to be punishing the Corvette team for being to awesome, it’s bs.
DON BJORKLAND IS CORRECT
CURB WEIGHT IS 3721, CURB WEIGHT IS NOT DRY WEIGHT
AND THAT’S WITHOUT THE CARBON FIBER WHEELS
LOADED WITH PEOPLE AND LUGGAGE IT IS 4021
THE 4 CAM MOTOR, STRONGER TRANS, AND SUSPENSION WEIGH MORE
The Z06 needs to go on a diet.
The C8 ZO7 needed twin turbos. With a base ZO6 curb weight at almost 3,800lbs, the ZO6 is an absolute failure without twin turbos. Then, the $106k is just a ridiculous joke.
The $60k base Stingray is, and will probably remain, the highlight of the C8.
😖 The Europeans Manufacturer are Laughing NOW at this Pig…. As a scientist I would have forgone the Open roof structure of the C8 to return to Coupe Only bird Cage C6 Z06 design. Anything above 3000LBS curb weight is NOT a supercar. Hence the Carbon Fibre Tubs as cockpit environment of the exotics… What happen to the use of Magnesium and Titanium🤔?….
LOOK AT HOW MANY FERRARI, LAMBORGHINI, AND PORSCHE CARS EQUIPPED LIKE THE C8 Z06 WEIGH OVER 3000 LBS.
THE Z06 Z07 WILL DO 0-60 IN 2.6 SEC. AND 1/4 MILE IN 10.6 SEC., DOESN’T THAT COMPETE
WITH MOST OF THE CARS THOSE COMPANIES MAKE.
THOSE COMPANIES WISH THEY COULD SELL AS MANY CARS AS THE CORVETTE.
Showing Gross Weight vs Curb Weight is misleading. Irresponsible of this writer to post GVWR as a headline grabber.
