Somewhat hesitant to make this post given the hornets nest the topic has stirred up at another forum site, but here, goes...

How concerned are you folks about the 200+ pound weight increase for the Z over the Stingray?

I know adding a super charger, aero pieces, larger wheels and tires, etc adds weight, but I was hoping they would find ways to minimize it further. I suppose they did such a good job keeping the base car's weight down that there may not have been cost effective methods to add to the Z. And since I wouldn't track my car (at least often or seriously) I also wouldn't want to give up the luxury items (heated seats, improved interior and so on).

The planner in me also says they could be setting up a couple of future editions/changes. Sure, maybe there won't be a ZR1, but down the road in a couple years as a mid cycle refresh they could swap some new lightweight parts, bump up the horsepower a bit and BAM! the car is keeping pace with progress. Built in future progress and enhancements. They could consider a track specific version where they remove some of the comfort items (radio, carpet, sound deadening materials, etc) for those who want a more hard core track vehicle.

Sure the above items were not mentioned in the 3 year plan that was posted, but I'm positive they didn't spell out everything they will or will not be doing over the next few years.

I'm at least a year and a half from possibly ordering a Z, so I might even be able to take advantage or a mid cycle refresh.

It weighs more than I wish, but it is more car than I had hoped it was going to be a year ago. It is just fine, worth about twice what is it will cost.

The extra weight the ZR1 has was not a problem and does very well in racing.
Could be a plus in preventing lift and more weight on tires for traction

Weight concerns? Yep. But to be honest, I need to lose weight more than the Z06!

The car is not a light weight, but it isn't the heaviest go-fast on the street either. I'm not going to lose sleep over it. Frankly, take 200 pounds off the car and for street use I'm not sure I am advanced enough of a driver to extract a meaningful benefit.

650hp? Not concerned at all if any lighter the car might actually fly. :)
Hahaa, nice one red:eek:

I would have liked to see it a little lighter. I was a bit surprised to see the figure. That being said the new Hellcat Charger is 100lbs heavier than the challenger and testers found it 2 tenths quicker in the quarter. Obviously chassis length etc could be a factor and yes I am aware it's not a track car etc etc. Reality is that the Z06 will still be a wrecking machine on straight track or bendy track. With the right suspension (which it has) one won't even notice the weight. Yes lighter would equal better track performance with the same set up etc but as has been stated more than once here, how many of us will have the talent and tackle to be able to unleash the cars full potential.........

Nice to hear that folks here aren't overly concerned with the weight.

I'm not, heck, compared to my daily driver, a G37x, the Z will have over twice the HP and about 3 times the torque if the supercharger helps minimize the high altitude power losses we have here in Denver. And the Z weighs a few hundred pounds less as well. I've read mixed opinions on supercharges and high altitude performance so I'll be interested to see some dyno numbers from around here. Hopefully someone will test it out.

It'll be interesting to see what it actually weighs. If the 3524# number is in fact accurate, it's about 50-75# heavier than I expected. We know a C7 Z51 1LT M7 car is ~3360-3375#, I expected the Z06 to be 75-100# heavier.
IMO, it's not going to hobble the car at all despite all of those who may claim that it's going to make the car hard on consumables when tracked. Look at it this way...the last C6 Z06 tested by MT was a Z07 Carbon Edition and it weighted 3320#.

I'm sure there are already claims that the C7 Z06 is close to 400# heavier than a C6 Z06. But those are invalid comparisons as that 31xx# C6 Z06 went out of production in 2007 as the cars steadily gained weight through 2013.

Of course those that might want to truly race this car and weight is an issue there are things that can be done to get the weight down like starting with the wheels. I'm sure you can find for example a lighter weight set. Also these being run flat tires I'm sure are heavier than regular tires. But for I'm guessing 90% of us weight is the least problem we have since it's just an adult toy. ;)

How many people do you suppose are going to take out a brand new, or even 1-2 year old C7 Z06 and track it to the point that a consumables budget is concern? The answer is: very, very few.
And when you're talking a ~200-300# difference, the claim that the car is going to be substantially harder on tires, brakes, fuel, etc. is completely unfounded unless talking with respect to competitive, wheel to wheel racing where...uhh...exactly nobody is going to be tracking a stock C7 Z06. :lol:

I could lose 50 pounds to help balance things out I guess.:eek:

In doing the math as to weight and HP both the C6 and C7 come out about the same a 6 pounds per every 1 HP so the boost of the C7 Z06 makes up for the added weight

C7 Z06 3524#/650hp = 5.42#/hp
C6 Z06 3320#/505hp = 6.57#/hp (2013 Carbon Edition Z07)
C6 Z06 3175#/505hp = 6.29#/hp (2006 Unicorn Lightweight Z06)

Looks like the C7 Z06 has at least a 16% #/hp advantage over the C6 Z06 (the 9-year old version), which means it must be compared to the C6 ZR1, lol.

Thanks for the clear explanation Snorman! Yowza, comparable to the C6 ZR1:eek:

....and that's just the horsepower.....Don't forget about the TORQUE! The old Z06 had 470, now we will be dealing with 650 lb.-ft !! It also comes one like a train in the low end with 457 just off idle. Can't wait to see some times. I almost forgot! Then factor in the extra gear in the manual or 2 gears in the auto vs the C6. Ohhhhh yeaghhh!

Honestly, the car should be compared to the C6 Z06. But since it's going to be quite a bit faster on-track and at the drag strip, the default comparison is with the ZR1 since...ya' know...they both have blowers.
