Sorry but that's not accurate with a full tank of gas. A buddy Beretta has one and he weighed it on his scales. It's every bit of 3400lbs filled up.

This is with 3/8 tank of gas. At 6.4 lbs/gallon for fuel and assuming a 19 gallon tank, lets round up to saying 1/2 tank or 9.5 gallons x 6.4lbs = another 60 pounds. 3390 + 60 = 3450.

I've seen other posts and they're all around 3450 fully wet. The ones showing < 3400 don't have a full tank of gas.

RapidC84B

This is false. The auto is only 6lbs heavier than the manual gearbox.

I was thinking you were about right with the 100 lb increase. Filled up c751 are around 3400 and the z's are looking like they are hovering around 3500.

Hi Tony...off topic, but I just wanted to say what's up.

My A6 2LT Z51 with ~3/4 tank of fuel. It took ~5-6 gallons of fuel as I recall after I drove the car across town and back to the bank...so figure ~3410# for an A6 2LT car (which has the subwoofer, heated/cooled seats, etc).

ChucksZ06's M7 1LT Z51 (I was slightly off in my recollection of what Chuck's car weighed).

3 Z06ZR1 weighed his M7 1LT Z51 on a truck scale and it was 3350#, although I'm not sure of the accuracy of those scales at such a low weight.

So I was probably off a couple of pounds regarding the delta between a base 1LT car and a Z51 1LT car. It's probably in the 80-90# range. Maybe a fully loaded 3LT car with who knows what options might hit that 3444#, but it wouldn't be apples-to-apples to a base car.

Seems like good round number are:

3300 base C7
3400 Z51 C7
3500 Z06 C7

PeteZ06

Yup.. Its too bad they wandered away from the idea of the Z06 being a lightweight raw race car.

I have mine down to 2950ish lbs.

stevebz06

I remember someone commenting that they asked Tad Juechter (sp?) about getting a blind spot warning system installed in the car and his response was that they were having a hard time finding room to install it.

I think that says a lot as to why the car is so heavy. And the requests keep coming in for more features, which I find depressing.

Everytime this question is asked on these forums, GM engineers add another 3 pounds to the Z06.

With all the items added to the C7 Z06 the only way they could reduce its weight would be through more Carbon Fiber like door panels, fender panels, trunk lid etc. If they did that, I sure would hate to venture a guess as to how much that version would cost. Be careful what you wish for...

JoesC5

A8 M5U weighs ~213 pounds and the M7 TR6070 weighs 144 pounds.

Then you have to add the weight of the flex plate and the torque convertor and the additional heat exchanger and lines used on the A8 and the dual mass flywheel and the clutch assembly used on the M7, to come up with a final difference in the car's weight.

ChucksZ06

Yup.

Carbon fiber is a cost prohibitive way to reduce weight when you consider how much seats, exhaust systems, etc. weigh.

Greg Quillen

long tubes alone probably drop 30lbs

I love lightweight cars but i do daily drive it so I like my vented seats and all the luxury..
If i really wanted a light weight track car Id be building something like the Factory Five GTM with a LT1 supercharged

OJCrush08

Yep, my 02 Z was probably a bit lighter than my 3LZ '10 Z which, after a few changes weighs in now at a race shop scale bustin' 3090 lbs (with fluids). Original weight was 3161. And, I have the APSIS seats, which are certainly heavier that the original crappy seats (and are much nicer than the new seats). I gotta believe that 625 emission legal h/p and over 600 ft/lbs of torque will move that 3090 lbs at least as well as the new Z - with no significant heat soak issues either.

Numbers don't lie, especially the most important number of all to any corporation - sales numbers. When the C6 GS was introduced, it offered the look of the Z cars in addition to auto trannies, removable tops, and Verts. And, it peeled away most potential buyers, folks who previously bought the Z cars for the "look." GM listened and learned, and I believe this experience set the direction of the new Z. A lot of "mission creep" from the original C5/C6 Z mission to create the lightest, most "pure" performance model.

Yes, the new Viper is lighter, much purer of purpose, but it also sells in quantities so low as to be unacceptable to any GM business case. GM made a business decision, and for them, probably the best one. It would have been nice if they had considered a "club sport" version for those of us who bought these cars based upon their original mission, but realistically, very understandable why they didn't.

It's not personal to GM, just good business. We make it personal...

Over-Rev

It would be nice if posted weights always listed:

1. With or without driver and weight of driver if they are included
2. Amount of fuel in tank (if exact amount is not known then the level on the fuel gauge will suffice)
3. Trim levels

What if one person weighs the car at a half tank and the other weighs full? Some are listing this but not all.

RapidC84B

OJCrush is right... the car makes perfect business sense for GM. They're selling the heck out of these cars. They know the hardcore enthusiast will modify the car on his or her own as they see fit. That's always been their standing reason for now "trackday" variant. However, I'd love to see one.

lt1z

Newer cars keep gaining weight with added electronics and and safety enhancements. It would be nice if they made a stripped down version similar to what the Z28 is with the camaro to drop 200 lbs or so.

JoesC5

I believe that I read that the "safety enhancements" added ~17-18 pounds to the C7. That leaves a lot of weight added for "other reasons" that are not mandated by the federal government, thus not necessary. BYW, the 3130 pound C6 Z06 also met it's required "safety enhancements" as did the 3199* pound 2013 Z06 and the 3333 pound 2013 ZR1.

* a good chunk of that weight increase was due to beefed up drivetrain components over the 2006 Z06, and was also in the 2009 ZR1 and also found in the 2015 C7 Z06.

RapidC84B

Beefed up driveline (but the Z06 has a carbon torque tube vs. steel in the base C7), direct injection fuel system, and heavier interior stuff (especially seats) are the main culprits. It all adds up quickly. Bigger/additional coolers add weight, the E-diff and all that stuff adds weight.

That's part of the reason I'm so disappointed the car has apparent cooling issues. It has separate radiators/coolers for the trans/diff and fans for each and this adds weight. The C6Z/ZR1 pumped the trans/diff fluid to the main radiator up front. Less weight, but more compromised cooling. The C7 with dedicated coolers and vents/ducts for everything should stay way cooler.
