Got the car out of storage, fueled it up and was driving by my local co-op that has a weight scale that's always on. Pulled the car onto it and once it settled the weight was exactly 4000#. I'm 260 lbs and I have a few cleaning supplies in the trunk (HTC) but I didn't realize I was cruising in a two ton sports car 🤪

I wouldn't remove anything or reduce the size. The car is amazing just the way it is. I don't want it to feel like a Miata.

too heavy a car in my opinion, did it really need to gain that much weight over a C7

Tadge Juechter (Executive Chief Corvette Engineer) in the 1+ hr interview on Autoline Afterhours when the C8 was released addressed the issue. He said:

Why Heavier:

• DCT inherently heavier as the needed cooling adds weight. More cooling is needed as the clutches require and optimum fluid temp to operate properly.
• Coil springs add weight over single leaf spring.
• The structural support of the coil springs adds weight and higher CD
• The 9mm glass separating the engine is twice the windshield thickness to reduce motor the accessor drives high pitched noise. Found that heavy glass on a Ferrari they stripped and they add noting that increases weight regardless of cost.
• Center structure support helps with rigidity. It has a 5mm aluminum plate held with bolts to close the bottom. (Note that may have been converted to composite since his interview.)
• New crash requirements added weight.

I think we both know how that 4000 pound number can be lightened up a bit. Helium in the tires isn’t it.

good info, good post, still a heavy car,

I was amazed of the weight of the cat-backs being 77 lbs. They could start trimming fat there on the C9.

Surprised too that the weight was 4K lbs. But, all the new stuff on the C8 does add a weight penalty.

JerryU

Thanks my good words and those of Tadge don’t make it any lighter

It is not 4000 lbs. My ERay is darn close but 0 to 60 in 2.5 seconds worth it !

Curb weight = 3647 on the low end. If you're 260, that's only around 90-100 lbs difference between that and what the scale weighed. So assuming that it was tared correctly, I would assert that the difference is purely what stuff you've added/modded, and probably trim/options.

Don't see why 4k pounds is a big deal though. Everyone acts like this is blasphemous, yet cars are over twice as powerful as they were back in the 1990s. The power:weight ratio on modern cars like the C8 SR is far superior to that of their 90s precursors.

MK4 supra was listed (on the low end) as 3214 lbs and 321 hp (conservative). that's about 10 lbs for every pony under the hood. For that 3647 lbs C8, that's about 7.3 lbs each pony is carting around.

And I don't think anyone would argue that an Mk4 Supra (nor a C4, C5, Z32, FD, or Z16) tracks (or likely handles) better than a C8 SR--despite some of them weighing considerably less. Yes, weight is bad, but let's be realistic here. When you factor in power:weight, skidpad (tire contact area, tire grip, etc), etc--the C8 is far and away a clearly superior car....hands down.

p.s.
If the ER is 4100 lbs, it would have a power:weight of 6.26 lbs per pony. That is practically double the ratio of a 1991 3000GT VR4--which is a good AWD performance comparison.

My 1LT Z51 coupe is right where it is suppose to be. GM lists 3577 curb weight and Im within a few pounds of that weighed on Intercomp scales with fuel. Add 260 +100 HTC + 40 trim and options + your supplies and it gets to 4000.

LOL!! Believe me I'm working on that too. Wasn't that long ago I was almost 290 lbs so at least I'm moving in the right direction. I'm not sure how much I've added to the weight of the car with a front splitter and full length side skirts but I can't imagine it'd be that much. Does the factory curb weight take into account various options like front lift or different spoiler options? I was just a bit surprised at the gross weight on the scale.

Lol....anyone see what EVs weigh? Batteries are really heavy....

A 2008 C6 weighed 3,200lbs

Now the C8 is pushing 4,000 lbs. Looks like it's time for some weight loss management

There is a post on this site from july 2014, a member in good standing weighed his car and did the corners as well, 3411 wet and fueled (Z51 car)
Google C7 Z51 they state curb weight 3298

car and driver measured a 23 C8 Z51 at 3747 wet

Acpantera

FWIW, my NY registration for my 24 SR no Z51 says 3465#

My C5 coupe with A4 trans weighs 3350 with me in it. It has upgraded suspension, 305 rear tires and 275 front tires, and I can whip it around a track just fine.
